8+(3/4w)

Step-by-step explanation:

8 for the miles she's already gone then plus 3/4 times number of weeks to represent how many more she'll go

Step-by-step explanation:

The formula of a volume of a cone:

\(V=\dfrac{1}{3}\pi r^2H\)

r - radius

H - height

We have

\(H=4m;\ 2r=3m\to r=1.5m\)

We have everything we need to calculate the volume of the cone.

\(V=\dfrac{1}{3}\pi(1.5)^2(4)\)

If we want to get the approximate volume, we must use the approximation of the number π.

\(\pi\approx3.14;\ \pi\approx\dfrac{22}{7}\)

\(V=\dfrac{1}{3}\pi(2.25)(4)=\dfrac{9\pi}{3}=3\pi\approx(3)(3.14)=9.42\ (m^3)\)

Cosine and sine rule are used to measure sides and angles. the measure of angle B is 34.6 degrees

According to cosine rule

BC² = 9.3²+15.5² - 2(9.3)(15.5)cos125.5
BC² =326.74 - 288.3cos125.5

BC² = 326.74 +167.41

BC = √494.15

BC = 22.23

Using the sine rule

15.5/sin<B = 22.23/sin125.5
sin<B = 12.62/22.23
sin<B = 0.5676
<B = 34.6 degrees

Estimation involves using a convenient value, close to the actual value, for calculations; especially in the absence of a calculator. The estimated number of gallons she needs to get to the station is 3 gallons.

Given that:

\(Speed= 70mph\)

\(Time = 1.25hr\) ---- equivalent of 1hr 15mins

\(Rate = 30 m/gallon\)

First, she will need to estimate the distance she can cover using:

\(Distance= Speed \times Time\)

An estimate of the calculation is:

\(Distance= 70mph \times 1.5 = 105m\)

The number of gallons is then estimated as follows:

\(Gallons = D ista nce\div Rate\)

Because the estimated distance is 105 m; she can use 35 as an estimate the rate of miles per gallon; instead of 30

\(Gallons = 105m \div 35m/gallon\)

\(Gallons = 3gallon\)

So, the estimated number of gallons she needs is 3 gallons.

We can check if the estimate is true or close by calculating the actual values.

\(Distance= Speed \times Time\)

\(D i s t a n c e= 70mph \times 1.25hr=87.5m\)

\(Gallons = D ista nce\div Rate\)

\(Gallons = 87.5m \div 30m/gallon =2.92m\)

Hence, the estimated number of gallons she needs to get to the station is 3 gallons.

"Your question is incomplete, probably the complete question/missing part is:"

There were approximately 11,000 students enrolled at Western Carolina last year. this figure goes up to about 225 students each year. Write a equation to model this situation.

The equation of the line parallel to 2x - y = 1 and with a y-intercept of 6 is y = 2x + 6.

To find the equation of a line parallel to the line 2x - y = 1 and with a y-intercept (b) of 6, we first need to determine the slope of the given line. The slope-intercept form of a line is y = mx + b, where m is the slope.

To find the slope, we rearrange the given equation in the form y = mx + b:

2x - y = 1

-y = -2x + 1

y = 2x - 1

From this equation, we can see that the slope of the given line is 2. Since a line parallel to this line will have the same slope, our desired line will also have a slope of 2.

Now we can write the equation of the line in slope-intercept form:

y = mx + b

Substituting the given slope (m = 2) and y-intercept (b = 6) into the equation, we get:

y = 2x + 6

Therefore, the equation of the line parallel to 2x - y = 1 and with a y-intercept of 6 is y = 2x + 6.

No, it doesn't show that single individuals under the age of 25 have more insurance claims than the nationwide percent reported by the big insurance firm.

Hypothesis

Null hypothesis : H0: p = 0.68

Alternative hypothesis : Ha: p > 0.68

A random sample of 53 claims showed that 41 were made by single people under the age of 25.

Thus; p^ = 41/53 = 0.7736

The test statistic is

z = (p^ - p_o)/√(p_o(1 - p_o)/n)

z = (0.7736 - 0.68)/√(0.68(1 - 0.68)/41)

z = 0.0936/0.07285

z = 1.28

The p-value from z-score calculator, using z = 1.28, one tail hypothesis and significance level of 0.05,we have;

P(z > 1.28) = 0.100273

Answer: 131.95 cm

Step-by-step explanation:

The diameter of the semicircle is 42 cm, which means the radius is half of that:

r = d/2 = 42/2 = 21 cm

The circumference of a full circle with radius "r" is given by the formula:

C = 2πr

Since this is a semicircle, we need to divide the circumference by 2:

C/2 = πr

Substituting the value of "r" we found above, we get:

C/2 = π(21)

Simplifying:

C/2 = 21π

C = 2(21π)

C ≈ 131.95

Rounding to the nearest hundredth, we get:

C ≈ 131.95 cm

Therefore, the circumference of the semicircle is approximately 131.95 cm.

Answer: x=85

Step-by-step explanation:

you want to isolate the variable, so:

Answer:

2

Step-by-step explanation:

One property of a triangle is that the sum of any two sides of a triangle is greater than the third side. Therefore, if the third side was represented by x, this would mean that :

17 + x > 16

16 + x > 17

17 + 16 > x

Since 17 is already greater than 16, there is no limit on x there. However, because 16 is 1 less than 17, x must be greater than 1. Furthermore, since 17+16 is 33, x must be less than 33. Therefore, the smallest whole number that fits these conditions is 2.

What is square root?

A value known as the square root of a number is one that, when multiplied by itself, yields the original number. An alternative to square rooting a number is to use it. Therefore, the concepts of squares and square roots are connected. The original number is equal to the square root of any integer, which is equivalent to a number.

Let's assume that m is an integer that is positive, such that (m.m) = (m2) = m.

This seems to be true because:

-2*-2 = 2*2 = 4

So √4 = 2 and -2

But particularly the square root of zero is:

√0 = 0

Answer:

\(f(x)=\begin{cases}x^2 + 3; & \text{ } x<1 \\ -2\cdot x+5; & \text{ } x\geq 1 \end{cases}\)

Step-by-step explanation:

The y-intercept (when x = 0) on the quadratic graph is 3, the upper quadratic graph does not intersect the x-axis, and the endpoint of the function has an open circle that stops at x = 1. The starting point extends to the boundaries of the graph

Therefore, the piecewise function shown in the quadratic graph is given as follows;

f(x) = x² + 3; x < 1

The straight line graph has a negative slope and starts at x = 1, with a closed circle, extending to higher values of x to the boundaries of the graph

Two points on the straight line graph are (1, 3) and (5, -5), therefore, the slope is (-5 - 3)/(5 - 1) = -2

The equation of the function is y - 3 = -2·(x - 1)

∴ y = f(x)  -2·x + 2 + 3 = -2·x + 5

f(x) = -2·x + 5; x ≥ 1

The function R(x) has one vertical asymptote at x = 0. (Choice A)

The function R(x) has one horizontal asymptote at y = 1/13. (Choice A)

The function R(x) does not have any oblique asymptotes. (Choice C)

Vertical asymptotes:

To find the vertical asymptotes, we need to determine the values of x for which the denominator becomes zero.

Setting the denominator equal to zero, we have:

13x = 0

Solving for x, we find

x = 0.

Therefore, the function R(x) has one vertical asymptote, which is x = 0. (Choice A)

Horizontal asymptote:

To find the horizontal asymptote, when the degrees of the numerator and denominator are equal, as they are in this case, the horizontal asymptote can be determined by comparing the coefficients of the highest power of x in the numerator and denominator. Therefore, as x approaches positive or negative infinity, the function approaches a horizontal asymptote at y = 1/13. (Option A)

Oblique asymptotes:

Since the degree of the numerator is less than the degree of the denominator (degree 1 versus degree 1), there are no oblique asymptotes in this case.

Hence, the function has no oblique asymptotes. (Choice C)
