<h3>Answer: Choice B (upper right corner)</h3>

==========================================================

Explanation:

At first the car isn't moving at all. This is at time 0. So this means the graph starts at the origin (0,0). Based on this alone, the answer is either choice B or choice C.

We can rule out choice C because the rates of change won't be constant to give those sharp straight lines. Instead, we have a gradual shift in speeds as the roller coaster progresses. So we'll have more of a curved shape as choice B shows.

Note that each time the car is going downhill, the speed goes up. On the flip side, as the car goes uphill, the speed goes down. So the direction of movement runs counter to the speed graph direction (one goes up, the other goes down).

A car rental company charges $10 a day and 17 cents per mile to rent their cars. If the total charge for a 2-day rental were $61

borishaifa [10]

Answer:

245 miles driven.

Step-by-step explanation:

A car rental company charges $10 a day and 17 cents per mile to rent their cars. 17 cents = 0.17 dollars

Let x be the number of miles and y be the number of days

total change =0.17x + 10y

Given total change is 61.65 and number of days = 2

plug in the values and find out the number of miles

61.65 = 0.17 x + 2(10)

61.65 = 0.17 x + 20

subtract 20 on both sides

41.65 = 0.17x

Divide by 0.17 on both sides

x = 245

245 miles driven.

If a fire engine is traveling down the interstate driving 55 mph and reaches the reported vehicle fire 13 minutes, approximately

sashaice [31]

Answer:

$\large \boxed{\text{12 mi}}$

Step-by-step explanation:

1. Convert miles per hour to miles per minute

$\text{Speed} =\dfrac{\text{55 mi}}{\text{1 h}} \times \dfrac{\text{1 h}}{\text{60 min}}= \text{0.917 mi/min}$

2. Calculate the distance

Distance = speed × time

$d = \text{13 min} \times \dfrac{\text{0.917 mi}}{\text{1 min}} = \textbf{12 mi}\\\text{The engine travelled about $\large \boxed{\textbf{12 mi}}$}$

X+y=3 x-3y= -29 Solve the system by using the elimination method

Sindrei [870]

Answer:

x= 16

y= -13

Step-by-step explanation:

x+y=3

x-3y=-29

Eliminate x and subtract the equations

2y=-26

y= -13

Plug in y for first or second equation

x=16

Csc x - sin x = cot x • cos x

bearhunter [10]

1) expand csc and cotx identity

(1/sinx)-sinx = (cosx/sinx)*(cosx)

2) get common denominator on the left side

(1-sin^2x)/(sinx)= (cos^2x)/sinx

3) using cos^2x+sin^2x=1 you finished
cos^2(x)/sinx= cos^2(x)/sinx

hope that helps<span />
