Answers
Answer:
1. Not Linear
2. Linear
3. Linear
4. Linear
Step-by-step explanation:
Linear means it follows the form y = mx + b
1. The x value increases by 2 each time, but the y value doubles each time. They are increasing at different rates, so they are not linear.
2. The x value is increasing by 3 each time, and the y value is deceasing by 1 each time. Slope (m) of this line would be -1/3
3. The x value is increasing by 4 each time, the y value is increasing by 3 each time. Slope (m) of this line would be 4/3
4. The x value is increasing by 1 each time, the y value is constantly -3. This means that the line is a horizontal line, which is linear with a slope of 0. So the equation of this line would be y = 0x -3 ----> y = -3

The Chu family can hike 3 miles per hour. How long will it take them to hike 15 miles?
A- 3.75 hours
B- 4 hours
C- 4.5 hours
D- 5 hours
Answers
Answer:
D- 5hrs
Step-by-step explanation:
If the family can hike 3 miles per hour,
for 15 miles: 15/3 = 5 hours.
Every hour they cover 3 miles per hour, so to cover 15 miles, they will take 5 hours
Answer:
D. 5 hours
Step-by-step explanation:
3 miles per 1 hour so 3/1
15 miles per x hours so 15/x
3/1 = 15/x or 3 = 15/x
get x by itself so
3 divided by 3 and 15 divided by 3
x = 5 hours

Work out the size of angle x
Answers
Answer:
x = 121°
Step-by-step explanation:
The lower left interior angle of the triangle is adjacent to 115° and are supplementary, thus
interior angle = 180° - 115° = 65°
The angle round a point is 360°
The vertex interior angle = 360° - 304° = 56°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, thus
x = 65° + 56° = 121°
Find the mean median range and mode for 3, 3, 4, 8, 9, 10, and 12
Answers
Answer:
Mean: 7
Median: 8
Range: 9
Mode: 3
Step-by-step explanation:
First, to find the mean of a set of numbers you need to add up all of the numbers and divide that by the total amount of numbers. In this case that makes this equation, \(\frac{3+3+4+8+9+10+12}{7}\), which is \(\frac{49}{7}\), which is 7.
To find a median you need to find the middle number. A handy trick I use for this is to place my fingers on the first and last number, and then move them towards the middle, at the same time by one number until there is just one number left in the middle. If there are no numbers left after doing this, meaning there are an even amount of numbers given, the median is the mean of the last two numbers that were covered. In this case, this is not necessary, so the median is 8.
The range is the difference between the maximum and minimum of a data set. In this case that would give you the equation Range=12-3, which means the range is 9.
Finally, the mode is the number that occurs the most in a given data set. In this case the number that occurs the most is 3, which occurs twice compared to every other number which only occurs once.

what is the repeated-measures t statistic for a two-tailed test using the following scores? i ii 3 7 2 6 8 6 7 5 a. –1.732 b. –0.577 c. 0.577 d. 1.732
Answers
There is no repeated-measures t statistic for this two-tailed test using the given scores.
The repeated-measures t statistic for a two-tailed test can be calculated using the following formula:
t = (mean difference - hypothesized mean difference) / (standard deviation of the mean difference / square root of sample size)
To calculate the mean difference, subtract the first set of scores (i) from the second set of scores (ii) for each pair:
(3 - 7) = -4
(2 - 6) = -4
(8 - 6) = 2
(7 - 5) = 2
The mean difference is the sum of these differences divided by the sample size:
(-4 + -4 + 2 + 2) / 4 = -4 / 4 = -1
To calculate the standard deviation of the mean difference, first calculate the squared differences between the mean difference and each individual mean difference:
(-1 - (-1))^2 = 0
(-1 - (-1))^2 = 0
(-1 - (-1))^2 = 0
(-1 - (-1))^2 = 0
Then, calculate the sum of these squared differences and divide by the sample size minus 1:
(0 + 0 + 0 + 0) / (4 - 1) = 0 / 3 = 0
Finally, calculate the square root of the result:
sqrt(0) = 0
Now, substitute these values into the formula:
t = (-1 - 0) / (0 / sqrt(4)) = -1 / (0 / 2) = -1 / 0 = undefined
Since the standard deviation of the mean difference is 0, the denominator becomes 0 and the t statistic is undefined.
Therefore, there is no repeated-measures t statistic for this two-tailed test using the given scores.

Transform f(x) to g(x) by translating f(x) 8 units to the left
Transform f(x) to g(x) by translating f(x) 16 units up
⇒ g(x) = f(x + 8)
⇒ g(x) = f(x) + 16
From inspection of the graph, the slope of f(x) is 2 and the y-intercept is -10. Therefore, the equation of f(x) is:
f(x) = 2x - 10
g(x) = f(x + 8)
= 2(x + 8) - 10
= 2x + 6
g(x) = f(x) + 16
= 2x - 10 + 16
= 2x + 6
Therefore, g(x) = 2x + 6
Find equation of f(x)
m=2b=-10Equation in slope intercept form
y=mx+by=2x-10So
x units is shifted 8 units right and y intercept is 16units far

The square of the distance between two points is the sum of the squares of the difference between two coordinates. The value of n can be -13 or 3.
What is the distance between two points?The distance between two points is given by the formula,
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
As it is given that the distance between points R and S is half the distance between points S and T.
\(2(RS) = ST\)
Now, the distance between RS can be written as,
\(RS=\sqrt{[-6-(-2)]^2+[-5-(-5)]^2}\\RS = \sqrt{(-6+2)^2+(0)^2}\\RS = \sqrt{16}\\RS = \pm 4\)
Further, we can write,
\(2(RS) = ST\\\\2(\pm 4) = \sqrt{[-2-(-2)]^2+[-5-n]^2}\\\\\pm 8 = \sqrt{(0)^2+(-5-n)^2}\\\\\pm 8^2=(-5-n)^2\\\\\pm8=(-5-n)\\\\\)
When the value of 8 is positive,
\(+8+5=-n\\\\13=-n\\\\n=-13\)
When the value of 8 is negative,

Answers
Answer:
A. Volume: 819, Surface Area: 598
B. Surface area
C. Volume
Step-by-step explanation:
Sorry I'm late, but here I go.
The volume of a rectangular prism is \(lwh\) or \(bh\). (l being length, w being width, and h being height.)
So if we multiply the 3 values of 13, 9, and 7, we get 819. This is the volume.
To find the surface area, we can take note that 4 sides are the exact same, and the remaining two are the same. Let's find the area of the top/bottom of the prism.
\(13\cdot9=117\)
Since there are two, bottom and top:
\(117\cdot2 = 234\).
Now, there are the remaining 4 sides. Let's find the area of one then multiply it by 4.
\(13\cdot7=91\\91\cdot4=364\)
Adding 364 and 234 gets up 598, so this is the surface area.
If we are painting something, the surface area is being painted, as we can't paint inside the box. However if we fill up the box with something (concrete in this case), it will be the volume.
Hope this helped!
Answer:
a.
v= 819 cm3
sa= 542 cm2
b. surface area
c. volume
Step-by-step explanation:
Volume of a rectangular prism: Length x width x height
Replacing with the values given:
V = 13 x 9 x 7 = 819 cm3
Surface area = S = 2 × (W × L + L × H + H × W)
S = 2 ( [9x13]+ [13 x7] +[7x9]) = 2 ( 117+91+63)= 542 cm2
b . Surface area, because we only have to paint the exterior of the brick.

Problem 1 Consider the plotted functions shown in Fig. 1. Complete the following for each plot: a) Determine an expression for f(t) by shifting and scaling 6(t), u(t), and r(t). b) If f (t) 56 0 V t < 0, time shift f(t) so that f (t) = 0 V t < 0. Determine an expression for the shifted f (t) 0) Determine the Laplace Transform F(s) of the expression obtained in part (b) (or part (a) if f (t) did not need to be shifted). Figure 1: Plotted functions
Answers
a) To scale it, we can multiply it by a constant, let's say B. Therefore, f3(t) = B * r(t) will be scaled.
b) f1(t) = A * 6(t)
f2(t) = u(t - t0)
f3(t) = B * r(t)
f(t) = 56 * u(t - ∞)
c) To determine the Laplace Transform F(s) of the shifted function f(t), we can use the time-shifting property of the Laplace Transform.
a) To determine an expression for f(t) by shifting and scaling 6(t), u(t), and r(t), let's analyze each function:
6(t) is the unit step function, which is 0 for t < 0 and 1 for t ≥ 0. To scale it, we can multiply it by a constant, let's say A. Therefore, f1(t) = A * 6(t) will be scaled.
u(t) is the unit step function, which is 0 for t < 0 and 1 for t ≥ 0. To shift it, we need to introduce a time delay. Let's denote the shifted function as f2(t) = u(t - t0), where t0 is the time delay.
r(t) is the ramp function, which is 0 for t < 0 and t for t ≥ 0. To scale it, we can multiply it by a constant, let's say B. Therefore, f3(t) = B * r(t) will be scaled.
b) The given function f(t) = 56 for t < 0. We need to time shift it so that f(t) = 0 for t < 0. To achieve this, we can introduce a time delay of t0 = ∞. The shifted function f(t) = 56 * u(t - ∞) will be zero for t < 0.
To summarize, the expressions for the shifted and scaled functions are:
f1(t) = A * 6(t)
f2(t) = u(t - t0)
f3(t) = B * r(t)
f(t) = 56 * u(t - ∞)
c) To determine the Laplace Transform F(s) of the shifted function f(t), we can use the time-shifting property of the Laplace Transform. The Laplace Transform of f(t) is given by F(s) = L{f(t)} = L{56 * u(t - ∞)}. Applying the time-shifting property, we have F(s) = 56 * e^(-∞s) / s.
In this problem, we analyzed the given functions and determined their shifted and scaled expressions. We also time-shifted the function f(t) so that it equals zero for t < 0. Finally, we obtained the Laplace Transform F(s) of the shifted function.

hi CO-ARMY
The first term of the AP is 4.522 and the common difference is 2.261.
What is the formula to calculate the nth term of an Arithmetic Sequence ?The formula to calculate the nth term of an Arithmetic Sequence is aₙ = a + (n - 1)dThe common difference [d] can be obtained as → d = a – a₁ = a₃ – a₂ or d = aₙ – aₙ ₋ ₁The Arithmetic Sequence can also be written in terms of common differences → a, a + d, a + 2d, a + 3d, a + 4d.The sum of [n] terms of an Arithmetic sequence will be :
Sₙ= n/2[2a + (n − 1) × d]
We have the sum of the first terms of an AP is 520. If the 7th term is double of the 3rd term.
We can write -
a[7] = 2a[3]
a + 6d = 2{a + 2d}
a + 6d = 2a + 4d
2d - a = 0
{2x - y = 0}
and
S[20] = (20/2)[2a + 19d]
52 = 2a + 19d
2a + 19d = 52
{19x + 2y = 52}
On solving, we get -
x = 2.261
y = 4.522
Hence, the first term of the AP is 4.522 and the common difference is 2.261.

the perimeter of square is 2. two cars start from and simultaneously and drive clockwise on the perimeter of square in the same speed. a drone maintains its location as the midpoint of the two cars. how far did the drone fly after both cars get back to where they started?
Answers
The distance the drone has flown after both cars get back to where they started is equal to the length of the diagonal of the square, which is approximately 0.7071.
Since the perimeter of the square is 2, each side of the square has a length of 0.5. Therefore, the total distance around the square is 2 x 0.5 = 1.
Both cars start at the same time and drive clockwise on the perimeter of the square, so they will meet each other exactly halfway around the square. At this point, the drone at the midpoint of the two cars will have flown a distance equal to half the perimeter of the square, which is 0.5.
After the cars complete one full lap around the square and return to where they started, they will have each traveled a distance of 1. Therefore, the distance the drone has flown at this point is equal to the distance between the two cars, which is also equal to the diagonal of the square. Using the Pythagorean theorem, we can calculate the length of the diagonal as follows:
d^2 = 0.5^2 + 0.5^2
d^2 = 0.25 + 0.25
d^2 = 0.5
d = sqrt(0.5)
Therefore, the distance the drone has flown after both cars get back to where they started is equal to the length of the diagonal of the square, which is approximately 0.7071.

For his long distance phone service, Ali pays a 7 monthly fee plus 7 cents per minute. Last month, Ali's long distance bill was 19.53 . For how many minutes was Ali billed?
Answers
Answer:

Step-by-step explanation:
From the information given, you know that the total cost of the long distance service is equal to 7 plus the result of multiplying 0.7 for the number of minutes:
Total cost=7+0.07x, where x is the amount of minutes.
Now, you can replace the total cost with 19.53 that is the amount Ali was billed and solve for x:
19.53=7+0.07x
19.53-7=0.07x
12.53=0.07x
x=12.53/0.07
x=179
According to this, the answer is that Ali was billed for 179 minutes.

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the line y = 5. y = x. y = 4. x = 0.
Answers
The volume of the solid generated by revolving the region bounded by the graphs of the equations y = x, y = 4, and x = 0 about the line y = 5 is (32π/3) cubic units.
To find the volume of the solid, we can use the method of cylindrical shells. The region bounded by the given equations is a trapezoidal region with vertices (0, 4), (0, 0), (4, 4), and (4, 0). When revolved about the line y = 5, it forms a solid with a cylindrical shape.
The height of each cylindrical shell is given by the difference between the y-coordinate of the line y = 5 and the equation y = x, which is 5 - x. The radius of each cylindrical shell is the distance from the x-axis to the line x = 0, which is simply x.
Integrating the volume of each cylindrical shell from x = 0 to x = 4, and using the formula for the volume of a cylindrical shell, we obtain:
V = ∫[0 to 4] 2πx(5 - x) dx
Evaluating this integral gives V = (32π/3) cubic units.
Therefore, the volume of the solid generated by revolving the given region about the line y = 5 is (32π/3) cubic units.
