Which of the following is the independent variable of F(G(x))?
O A. V
• B. x
• C. F(x)
• D. F(G(x))

Answer:

x = 36

The measure of the exterior angle is 114°

The remote interior angles are 24° and 90°.

Step-by-step explanation:

The angle marked 3x + 6 is the exterior angle. The other two marked angles are called "remote interior angles"

The two remote interior angles added together equals the exterior angle.

3x+6 = 24° + 2x + 18

Combine like terms.

3x + 6 = 2x + 42

Subtract 2x from both sides.

x + 6 = 42

Subtract 6 from both sides.

x = 36

If required, use the x=36 to find the measure of the exterior angle.

3(36) + 6

= 108 + 6

= 114°

Or find the measures of the remote interior angles.

2(36) + 18

= 72 + 18

= 90°

The remote interior angles are 24° and 90°.

Answer:

Step-by-step explanation: You want to figure out how much it costs per ounce. You’ll divide $4.50/18 ounces to get $0.25 per ounce for the 18 ounce bag and $8.80/40 ounces to get $0.22 per ounce for the 40 ounce bag. The 40 ounce bag is cheaper per ounce.

Answer:

$24.50

Step-by-step explanation:

In order to predict the cost of an order with 6 boxes, x has to be equal to 6.

So we have to use the function 3.25x + 5 for [tex]x\geq 6[/tex].

Then, plug in 6 for x and solve.

3.25(6) + 5 = 19.50 + 5 = 24.50

The total amount given the original price and tax rate is $33.59

From the question, we have the following parameters:

Original price = $31.69

Sales tax rate = 6%

In order to determine the total sales amount, we make use of the following total sales equation

Total sales = original price + original price * sales tax rate

Substitute the known values in the above equation

So, we have the following equation

Total sales = 31.69 + 31.69 * 6%

Evaluate

Total sales = 33.59

Hence, the total amount is $33.59

The shortest total length of fence this can be done with will be 440 m as the total area is 2000 m².

The length of a shape's outline is its perimeter. You must add the lengths of all four sides of a rectangle or square to determine its perimeter. In this instance, x represents the rectangle's length and y its width. The distance around an object is called the perimeter. For instance, the yard of your home is fenced in. The fence's length serves as the perimeter. Your fence is 200 feet long if the yard is 50 feet by 50 feet.

Here,

The area=2000 m²

xy=2000

x=2000/y

p=4x+2y

p=4*(2000/y)+2y

The sides of the triangle are 150m, 200m and 250m.

What is distance?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Given: The sides of a triangle are in the ratio of 3:4:5. A man jogged around it 5 times and cover a distance of 3000m.

As man jogged around triangle  5 times and cover a distance of 3000m.

So, the distance for one round is 3000/5 = 600m.

The covered distance is nothing but the perimeter of the triangle.

So, the perimeter of the triangle is 600m.

Let, 3x, 4x, 5x are the sides of the triangle.

⇒ 3x + 4x + 5x = 600

                 12 x = 600

                      x = 50

Therefore,

3x = 3(50) = 150

4x = 4(50) = 200

5x = 5(50) = 250

Hence, the sides of the triangle are, 150m, 200m and 250m.

What is Kinetic energy?

Kinetic energy is the energy possessed by the body by virtue of its motion

If m is the mass of the body and v is the velocity of the body, then kinetic energy is given by the formula

Kinetic energy = [tex]\frac{1}{2} \times m \times v^2[/tex]

Let the mass of the airplane be m kg

Velocity = 220 m/s

Kinetic energy = [tex]\frac{1}{2} \times m \times (220)^2[/tex]

By the problem,

[tex]\frac{1}{2} \times m \times (220)^2 = 10890\times 10^6[/tex]

[tex]m = \frac{10890\times 10^6\times 2}{220\times 220}[/tex]

m = [tex]0.45 \times 10^6[/tex] kg

The length and width of a rectangle that maximises the enclosed area are 800 yards. The maximum area is 640,000 square yards.

In the given question we have to find the maximum area of the rectangular area.

Liana has 3200 yards of fencing to enclose a rectangle.

As we know that the perimeter of rectangle

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 3200

Divide by 2 on both side we get

x+y = 1600................(1)

From the area of rectangle is

A = xy

From the equation the value of y is 1600-x.

Now putting the value of y

A = x(1600-x)

A = 1600x-x^2

On differentiating

dA/dx = 1600-2x

Putting dA/dx=0

1600-2x=0

Subtract 1600 on both side we get

-2x= -1600

Divide by -2 on both side we get

x = 800 yards

Now putting the value of x in the y=1600-x

y=1600-800

y=800 yards

So the maximum area is

A= 800*800

A= 640,000 square yards

Hence, the length and width of a rectangle that maximises the enclosed area are 800 yards. 640,000 square yards is the maximum area.

The likelihood that the measured distance will be shorter than the actual distance is equal to 0.3085.

In this case, the chance that the measured distance will be less than the true distance will be determined using the z-score formula. The z score is a normal score that adheres to a normal distribution with a mean and standard deviation of 0 and 1, respectively.

Given that,

Mean, μ = 50

Standard deviation, σ = 100

Less than 0% of the time, the overestimation is likely.

Consequently, the necessary probability is P (X ≤ 0)

Now,

P (X ≤ 0) = P [(X − μ) / σ ≤ (0 − μ) / σ]

P (X ≤ 0) = P [Z ≤ (0 − 50) / 100]

P (X ≤ 0) = P [Z ≤ − 0.5]

Excel formula for the probability mentioned above:

The values of a and b are 8 and - 9.

Given that:

f(x) = x + a/x + b ........ (1)

f(1) = 0, f(2) = - 3

Putting the value of x = 1 in equation (1). We get,

f(1) = 1 + a/1 + b

f(1) = 1 + a + b ....... (2)

Putting the value of x = 2 in equation (1). We get,

f(2) = 2 + a/2 + b

f(2) = (4 + a + 2b)/2 ........ (3)

Putting the value of f(1) = 0 in equation (2). We get,

a + b = - 1 ......... (4)

Putting the value of f(2) = -3 in equation (3). We get,

=> -3 = (4 + a + 2b)/2

=> -6 = (4 + a + 2b)

=> a + 2b = - 10 ......... (5)

To find the value of a and b we have to solve equations (4) and (5) by elimination method.

So, for that subtract equation (4) from (5).

We got the value of b = - 9.

Then put the value of b in equation (4).

We got the value of a = 8.

A rate of change is a rate that describes how one quantity changes in relation to another quantity. If x is the independent variable and y is the dependent variable, then. rate of change = change in y / change in x. Rates of change can be positive or negative.

h(t) = -16[tex]t^{2}[/tex] +40t + 7

at maximum height the rate of change of h(t) with respect to t is zero.

so [tex]\frac{dh(t)}{dt}[/tex] = 0
