The equivalent expression to Daryl's expression is -5 + 7d ⇒ d

Step-by-step explanation:

In a regular polygon of n-side

  • All sides are equal in lengths
  • All angles are equal in measures
  • Its perimeter is n × the length of one side

∵ The polygon is a pentagon

∴ n = 5

∵ The pentagon is regular

∴ The lengths of its 5 sides are equal

∵ Its perimeter = 5 × length of one side

∵ Its perimeter = 35d - 25

- Equate the two sides of the perimeter

∴ 5 × length of one side = 35d - 25

- Divide both sides by 5

∵ 35d ÷ 5 = 7d and 25 ÷ 5 = 5

∴ The length of one side = 7d - 5

Daryl's expression is 7d - 5

Now lets check the answers

a. 35d - 25 ⇒ No

b. 7d - 15 ⇒ No

c. 5(35 - 25) ⇒ No

d. -5 + 7d ⇒ Yes

e. (35d - 25) ⇒ No

The equivalent expression to Daryl's expression is -5 + 7d

25. An apple is launched directly upward at 64 feet per second from a platform 80 feet high. The equation for this
Viktor [21]

Answer:

a. 144 ft

b. 5 s

Step-by-step explanation:

h = -16t² + 64t + 80

a. This is a parabola, so the maximum height is at the vertex.

t = -64 / (2 × -16)

t = 2

h = -16(2)² + 64(2) + 80

h = 144

The apple reaches a maximum height of 144 ft.

b. 0 = -16t² + 64t + 80

0 = t² − 4t − 5

0 = (t + 1) (t − 5)

t = -1 or 5

t must be positive, so it takes 5 seconds to reach the ground.
