Answer: 233.53 seconds

Step-by-step explanation:

Since we aren't given any further information in the question, the best time for the race based on the information given will be the addition of the top speed for each leg. This will be:

= 56.81 + 59.22 + 57.39 + 60.11

= 233.53 seconds

Therefore, the best time for the race is 233.53 seconds.

Answer:

b. 12π

Step-by-step explanation:

C= 2πr

R= D/2= 12/2= 6

C= 2x3.14x6

2x6= 12

C= 12π

Given :-

Then,

Using Formula

★Circumference of circle = 2πr

Keep Value

==> Circumference of circle = 2π × 6

==> Circumference of circle = 12π

The equation that represents the given situation is 12 + 6x = 30.

The number of additional hours is 3.

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

A trampoline park costs $12 for the first hour and $6 for each additional hour.

Amount paid at the park = $30

Now,

12 + 6x = 30

x is the number of hours.

Solve for x.

12 + 6x = 30

6x = 30 - 12

6x = 18

x = 3

Thus,

The equation is 12 + 6x = 30.

The number of hours is 3.

Answer:

Step-by-step explanation:

when you use elimination you want to set two of the terms, in the different equations,  equal to each other and then subtract the entire equation from the other,  so that the two terms cancel out.    Then you have an equation with one less variable in it.  :)

Answer:

Slope = 1

y-intercept = 3

Step-by-step explanation:

Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through two points (0, 3) and (-3, 0) will be,

Slope = [tex]\frac{3-0}{0-(-3)}[/tex]

Slope = 1

y-intercept of the line = distance between the origin and point of intersection of the line with y-axis

y-intercept = 3

-9x^2+13x+8

Step-by-step explanation:

Combine like terms-

(x^2 + 8x + 8) + (-10x^2 + 5x)

8x+5x = 13x

(x^2 + 8x + 8) + (-10x^2 + 5x)

-10x^2+x^2 = -9x^2

(x^2 + 8x + 8) + (-10x2 + 5x)

and 8 is just left over, so we put that all together and get...

-9x^2+13x+8

Answer:

D is the correct answer

Explanation:

the following function satisfies each output to its input for the set D

f(x)=x/2

let's check each pair:

0/2=0

-1/2=-0.5

-2/2=-1

-3/2=-1.5

-4/2=-2

the reason why A, B, and C can't be pairs of inputs and outputs x and y it's because a variable x can't have more than one y (that's a behaviour of an equation not a function!)

- in A x=-1 | y=2, -2 and this wrong

- in B x=3 | y=9, 16 and this wrong

- in C x=0 | y=0, 1 and this wrong
