Answer:

20 m

Step-by-step explanation:

The maximum height is given by the vertex form of the equation, that is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

h(t) = - 5t² + 20t ← factor out - 5 from each term

      = - 5(t² - 4t)

Using the method of completing the square

add/subtract ( half the coefficient of the t- term)² to t² - 4t

h(t) = - 5(t² + 2(- 2)t + 4 - 4 )

      = - 5(t - 2)² + 20 ← in vertex form

with vertex = (2, 20 )

The maximum height is at the value of k = 20

That is the maximum height is 20 m

Find the area of a polygon with vertices at (1, 3), (7, 3), (7, 7), and (4, 7). a. 24 units2 b. 10 units2 c. 12 units2 d. 18 uni
maria [59]

Answer:

Option D

Step-by-step explanation:

Vertices of the polygon are A(1, 3), B(7, 3), C(7, 7), D(4, 7)

Measure of AB = 7 - 1 = 6 units

Measure of BC = 7 - 3 = 4 units

Measure of CD = 7 - 4 = 3 units

From the figure attached,

Area of the trapezoid = \frac{1}{2}(AB+CD)(BC) [Here, AB and CD are the parallel bases and BC is the height of the trapezoid]

                                    = \frac{1}{2}(6+3)(4)

                                    = 18 square units

Therefore, Option D will be the correct option.

HELP asap pls. <3
zimovet [89]

Step-by-step explanation:

I have no idea if I'm doing it right but my guess would be to take the values that we get from f(x) and g(x) when x = 1.  Therefore we get that f(x) is equal to 4 and g(x) is equal to -1.  We than just do f/g which is 4/-1 which gives us the final answer of -4 which is option B.

Answer:  Option B, -4
