Answer:

no

Step-by-step explanation:

it was slower the way there and if he was going 40 it would have taken the same time to get there as it would have to go back

Answer:

Yes.

Step-by-step explanation:

Reiko's average speed was 80 miles per hour. That is more than 40 miles per hour. Even if it took him longer to drive from A to B, his speed would still be more than 40 miles per hour to have the average speed be 80 miles per hour.

Hope this helps!

Evaluate the function f (x)  4 • 7x for x  1 and x = 2. Show your work
SashulF [63]
The function and the first value stated for x are confusing.

Doing some research, I found that the problem is to evaluate the function   f(x)=4.7^x    for x = - 1 and x  2.

The solution is:

1) For x = - 1

f(-1)=4. 7^{-1} =4. (1/7)=4/7

2) For x = 2

f(2)=4.7^2=4(49)=196

What the answer is and how?
sladkih [1.3K]

Answer:

PerimeterFigure= pi*DIameter/2= 1.5*pi ft.

Step-by-step explanation:

The perimeter is the length of the figure, since we are dealing with an semi-circle, we can use the perimeter equation for a full circle and divide it by half.

Perimeter= 2pi*R= pi*Diameter.

Since Our figure is a semi circle, as we say earlier, we now will divide the above result by half.

PerimeterFigure= pi*DIameter/2= 1.5*pi ft.
