The missing ordered pairs that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).

The equation given is y = 2x + 4. To compute the missing x and y values, we need to substitute the given ordered pairs into the equation and solve for the missing variable.

Let's assume we have an ordered pair (x, y) that satisfies the equation y = 2x + 4.

For example, let's say one missing value is x = 3. We can substitute this into the equation:

y = 2(3) + 4

y = 6 + 4

y = 10

So, the missing ordered pair is (3, 10).

Similarly, if another missing value is y = 8, we can substitute this into the equation and solve for x:

8 = 2x + 4

4 = 2x

x = 2

So, the missing ordered pair is (2, 8).

In summary, the missing x and y values that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).

Answer: B

Step-by-step explanation:

The y-intercept is the number that is a constant. It is the "b" in y=mx+b. The y-intercept is the point on the y-axis. That means the x-coordinate is 0. With this information, we can automatically eliminate C and D.

Since we know y-intercept is the "b" on y=mx+b, we know that 6 is the "b" in the given equation. Therefore, B is the right answer.

Using the interpretation of the confidence interval, it is found that:

It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.

What is the perimeter of a rectangle if it is 20 long and 11 wide?

The exact values of cos 2θ and sin(θ/2) are 9/25 and ± 0.955 respectively

Given that: sinθ = (2√2)/5  and π/2 < θ <  π

This implies θ is between angles 90° (π/2) and 180° (π). So θ  is in the 3rd quadrant as shown in the attached image.

Since  sinθ = (2√2)/5, we labeled the sides as shown in the image

Using the attached image:

cosθ =  -√17 / 5 (adj. / hyp.)

Using trigonometry identity:

cos2θ = 1 - 2sin²θ

cos2θ = 1- 2((2√2)/5)²

cos2θ = 1 - 16/25

cos2θ = 9/25

sin(θ/2) = ±√((1-cosθ)/2)

sin(θ/2) = ±√( (1 -(-√17 / 5))/2)

sin(θ/2) = ± 0.955

Therefore, the exact value of cos 2θ is 9/25 while the exact value of sin(θ/2) is ± 0.955

Answer:

  162

Step-by-step explanation:

There are many ways to work this. Perhaps the simplest is to recognize that 45% of the number is the difference between 55% of it and 10% of it.

  0.55n -0.10n = 0.45n

  198 -36 = 0.45n = 162

45% of the number is 162.

_____

If you like, you can find the number as ...

  0.10n = 36

  n = 36/0.10 = 360

Then you can verify (if you like), that 55% of it is 198:

  0.55(360) = 198 . . . . true

Finally, you can figure 45% of it:

  0.45(360) = 162

__

Using proportions, you can determine the number to be ...

  36/0.10 = n/0.45

  n = 0.45(36/0.10) = 4.5(36) = 162

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

The equivalent equation of  r sinθ = 10 in rectangular coordinates is y²  +   y⁴/x² - 100 = 0.

The rectangular coordinates is calculated from the polar equation as follows;

r sinθ = 10

the conversion from polar to rectangular coordinates;

r² = x² + y²

r = √(x² + y²) ----- (1)

y/x = tanθ  ------ (2)

r sinθ = 10

√(x² + y²)(y/x) = 10

The solution to the equation ln {A} = .552 is A = e\(^{0.552}\) = 2.7. In order to calculate eˣ for both sides of the equation ln {A}=.552, one must first understand what the equation signifies.

A logarithmic equation is an equation involving logarithms of different variables. Logarithmic equations are used to solve various types of problems. It uses the logarithmic properties of multiplication and division to simplify the equation.

This equation is a logarithmic equation, in which ln (natural logarithm) is used to represent a number's exponential value.

This means that the equation is actually stating that A is equal to e raised to the power of 0.552 (e\(^{0.552}\) ).

In order to solve for A, one must use the basic rule of logarithms: for any logarithmic equation of the form ln {A} = B, A = e^B.

Therefore, the solution to the equation ln {A} = .552 is

A = e\(^{0.552}\) .

This equation can be solved using basic algebra, as e\(^{0.552}\)  can be replaced with an equivalent expression.

The equation can be rewritten as A = (e\(^{0.5}\))(e\(^{0.052}\)).

The value of e\(^{0.5}\) can be calculated using a calculator, and can be rounded to the nearest tenth.

The value of e\(^{0.052}\) can then be calculated, which can also be rounded to the nearest tenth.

Adding the two values together will give the solution to the equation, which is A = 2.7.

Therefore, the solution to the equation ln {A} = .552 is

A = e\(^{0.552}\)

= 2.7.

Answer:

C.  5x(-x + 2)

Step-by-step explanation:

To factor the expression -5x² + 10x, we need to look for a common factor that can be factored out.

Finding a common factor involves identifying a term or expression that can be factored out from each term of a given expression.

Both terms have the common factor of 5x, so we can factor out 5x:

5x(-x + 2)

Therefore, the factored form of -5x² + 10x is -5x(x - 2).

\(\hrulefill\)

Additional notes:

If we expand the expressions in the given answer options, we get:

  A.  −5x(x + 2) = -5x² - 10x

  B.  5(−x² + 10x) = -5x² + 50x

  C.  5x(−x + 2) = -5x² + 10x

  D.  x(5x + 10) = 5x² + 10x

Hence confirming that the correct answer is option C.

To factor \(-5x^2+10x\), we can begin by factoring out the greatest common factor, which is \(-5x\):

We can check our answer by distributing \(-5x\) to the expression inside the parentheses:

\(\therefore\) The answer is \(-5x(x-2)\).

Step-by-step explanation:

the formula of the "relation" is

x² + y² = r²

this is for circle with its center at the origin.

now that gives us

y² = r² - x²

y = ±sqrt(r² - x²)

a. this ± of the square root gives us the 2 functions.

y = sqrt(r² - x²)

y = - sqrt(r² - x²)

as it is a circle, the ranges and domains are the same.

domain is the allowed number interval for x, and range is the number interval for y (the function results).

both are

-r <= x <= r

outside of that range the square root argument becomes negative, and that is undefined for R (the set of real numbers).

b. if we want to see it that way, we can say that

f(x) = r² - x²

g(x) = sqrt(x)

and so

sqrt(r² - x²) = g(f(x))

a function into function.

c. let's pick the "positive" semicircle

y = g(f(x)) = + sqrt(r² - x²)

f(x) = r² - x²

the domain is all x (-infinity < x < +infinity)

the range is (-infinity < y <= r²), as negative and positive larger x will turn f(x) negative. the functional results cannot get bigger than r² (for x=0).

g(x) = +sqrt(x)

the domain is all positive x incl. 0 (0 <= x < +infinity), as sqrt is not defined for negative values. at least not in R.

the range is also all possible positive values incl. 0

(0 <= y < +infinity).

d.

A one-to-one correspondence function is a function between the elements of the two sets of domain and range, where each element of one set is paired with exactly one element of the other set, and each element of the other set is paired with exactly one element of the first set.

that means, every x value creates exactly one y value, and no y value occurs more than once.

this is no true for

f(x) = r² - x²

because for -r <= x <= r we get the same y for -x and +x.

it is true for

g(x) = sqrt(x), as no 2 different numbers have the same square root.

Answer:

The circumference of a circle is calculated using the formula: C = πd, where C represents the circumference and d represents the diameter of the circle.

In this case, the diameter of the circle is given as 24 inches.

Using the formula, we can substitute the values:

C = πd

C = 3.14 * 24

C ≈ 75.36 inches

Therefore, the circumference of a circle with a diameter of 24 inches (and using π = 3.14) is approximately 75.36 inches.

On most days the temperature varied about 4.3 degrees from the mean temperature.

Step-by-step explanation:

The MAD is known as the Mean Absolute Deviation for any given dataset.

The absolute deviation is a measure of dispersion which quantifies the spread of the variables in the dataset from the mean.

It gives the only the positive value of the deviations of each variable from the mean.

The mean absolute deviation now signifies the average of the sum of all of these positive deviations of each variable from the mean.

Hence, the MAD value only gives how much the variables will varubfrom the mean on average.

Looking at the statements, it is evident that the MAD temperature value of 4.3 doesn't directly give the maximum or minimum variation from the mean temperature or the highest variation from the mean, rather it does show that 'On most days the temperature varied about 4.3 degrees from the mean temperature'.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.
