A cliff diver strikes the water with a velocity of 32 square root 5 feet per second. Find the height which the diver dove. V=square root 2gh

80

Step-by-step explanation:

equation

v = feet/s

g = 32 feet/s^2

plug in values

=

32 * 5 = 2h

h = 32 * 5 / 2

h = 80

expression #3 is not equivalent. the others are.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
