Answer : f(5) = 75

We use the given graph

From the graph we can see that when x=5  the value of y is 75

So h(5) = 75. It means at 5 second the height of the ball is 75 ft

Also when x=0  the value of y is 5

so f(0) = 5. This means at 0 second the height of the ball is 5 ft

Hence, option 1  is correct

$252

Step-by-step explanation:

The TV, which cost $400, is on sale for 30% off. So, let's find the price.

0.30 × 400 = 120

400 - 120 = 280

The TV is on sale for $280. But, there is also 10% off the sale price since it was a floor model. So,

0.10 × 280 = 28

280 - 28 = 252

The price of the TV before taxes is $252.

This is not the same as 40% off because that would make the price of the TV $240.

0.40 × 400 = 160

400 - 160 = 240

Hope that helps.
