Answer:

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the x-axis and time on the y-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

Step-by-step explanation:

the shape DEF went to the right along the x axis wich increased x and then went down the y axis or decreased y to make D'E'F'

some good way to remember these translations and orders are...
 - x is first when plotting points, then y (x, y)
 - x increases going right, and decreases going left, as well as y increasing going up, then decreasing going down

BONUS FACT:
the symbol ( ' ) is called a prime when refering to transformations and geometry ((as in D' is pronounced D prime))

14 miles

Let "Candler" be known as "C" and "Oteen" as "O"

Given:

3.5 ------> 3.50

Comparing the rate (inches/mile) and the distance:

Multiplying both sides by 100:

Clearly, 350 is divisible by 25 as "50" is divisible by 25.

Divide both sides by 25 to isolate x:

The actual distance between the two cities is 14 miles.

Answer:

14 miles

Step-by-step explanation:

Given:

Let [tex]x[/tex] be the distance between Candler and Oteen in miles.

[tex]\implies \dfrac14:1=3 \frac12:x[/tex]

[tex]\implies \dfrac{\frac14}{1}=\dfrac{\frac72}{x}[/tex]

[tex]\implies \dfrac14x=\dfrac72[/tex]

[tex]\implies x=\dfrac72 \div \dfrac14[/tex]

[tex]\implies x=\dfrac72 \times \dfrac41[/tex]

[tex]\implies x=\dfrac{28}{2}[/tex]

[tex]\implies x=14[/tex]

Remark

The base of the figure is a pentagon

The area of the base of a pentagon is

A=(1/4) * √[5(5+2√5)] * s2

The Formula for the Volume of a "pyramid" of this nature is

Volume = Base * h / 3

Givens

h = 10 feet

s = 8 feet

Base = formula in the remark section

Solution.

Find the base first.

A=(1/4) * √[5(5+2√ 5)] * s2     Find the value of 5 + 2√5

Area = 0.25√[5*(9.47)] * s^2 Find what is under the root sign

Area = 0.25√47.36   * s^2     Take the square root of 47.36. use s = 8

Area = 0.25 * 6.88 * 8^2         Combine.

Area = 110.11

Now find the volume

V = B * h/3

V = 110.11 * 10 / 3

V = 367.04     cubic feet.

The expression that represents the volume of the composite figure is 16/3πr³ + r³

The given parameters are:

The volume of a cube is:

V = l³

So, we have:

V = r³

The volume of a hemisphere is:

V = (2/3)πr³

So, we have:

V = (2/3)π(2r)³

Evaluate

V = (2/3)π * 8r³

This gives

V = 16/3πr³

Add both volumes

Volume = 16/3πr³ + r³

Hence, the expression that represents the volume of the figure is 16/3πr³ + r³

Answer:

Your answer is C, 14ft

Step-by-step explanation:

Your Given Measurements (in feet):

Height = 5 1/2 ; Width = 1 1/2

___________________________________________________

The Perimeter Formula:

L + W + L + W = P

In this case, the "L" which is length going to get substituted as Height.

5 1/2 is 5.5 because if you do 1/2 on the calculator, you get 0.5 which you can add 5 to get 5.5.

1 1/2 is 1.5 which is the same as the 5 1/2.

____________________________________________________

Now do 5.5 + 1.5 + 5.5 + 1.5 = perimeter

5.5 + 1.5 = 7

7 + 7 = 14ft

Your answer is C: 14 ft

Step-by-step explanation:

When a polynomial is shown in factored form, its zeros are the values of x that make the factors zero.

  The factor x is zero when x=0.

  The factor (x+4) is zero when x=-4.

  The factor (x+5) is zero when x=-5.

__

The multiplicity of a zero is the number of times a given factor is a factor of the polynomial. It is the exponent of the factor.

 x = 0 has multiplicity 3.

  x = -4 has multiplicity 2.

  x = -5 has multiplicity 2.

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles

Answer:

Set up an equation using these key terms:

Form the equation by piecing these key terms together:

63/100(63%) ×(of) X(The number being sought) = 792("-is 792)

63/100 × X = 792

(63/100 can be simplified to 0.63)

So, rewrite the equation to:

0.63 × X = 792

Solve for x!

0.63x = 792

Isolate 'x' by dividing 0.63 from both sides because the inverse operation of multiplication is division.

÷0.63 ÷0.63

x = 1,257.14285714 which can be rounded to 1,257.14.

Therefore, the number being sought is 1,257.14.

Hi!

Your answer is [tex]5x^2-7x-8[/tex].

We are asked:

[tex](-3x^2-5x+1)+(8x^2-2x-9)[/tex]

As we are adding them, we can remove the parenthesis.

[tex]-3x^2-5x+1+8x^2-2x-9[/tex]

Now, we can switch the order of the terms around to cause like terms to be by each other:

[tex]-3x^2+8x^2-5x-2x+1-9[/tex]

Finally, add like terms:

[tex]5x^2-7x-8[/tex]

5x² -7x -8 is the result of adding the polynomials -3x²-5x +1 and 8x²-2x-9. The result obtained by combining the like terms.

The two polynomials are  -3x²-5x +1 and 8x²-2x-9.

To add the two polynomials, you simply combine like terms.

Like terms are terms that have the same variable raised to the same power.

In this case, the variables are x² and x.

Let's add the given polynomials:

= -3x²-5x +1 + 8x²-2x-9

Group the like terms:

= -3x²+ 8x²-5x-2x+1-9

Combine like terms:

= 5x² -7x -8

Hence, 5x² -7x -8 is the result of adding -3x²-5x +1 and 8x²-2x-9.
