Use the Pythagorean Theorem:
a² + b² = c²
4² + b² = 8.5²
16 + b² = 72.25
        b² = 56.25
        b = 7.5

 The ladder reaches a height of 7.5 ft on the wall

Answer:

it is 3.00

Step-by-step explanation:

as you can see first we define the variables

1. the y axis(vertical) represents the cost of peaches while the x axis (the bottom one) represents the number of pounds

2. then we find a place where the line crosses the grid but exactly on the corner of the box

3. when we have found our point which is (2,6) it means that every 2 pounds of peaches is 6 dollars

4. divide 6/2 and you get 3 dollars!

A bird releases waste from a height of
shepuryov [24]

Answer:

5secs

Step-by-step explanation:

Given the equation of the height expressed ad;

h(t) = - 16t^2 + initial height

Given that initial height = 400feet

h(t) = - 16t^2 + 400

The waste will hit the ground at when h(t) = 0

substitute

0 =  - 16t^2 + 400

16t^2 = 400

t² = 400/16

t² = 25

t = √25

t = 5secs

Hence it will take the easte 5secs to hit the ground
