Answer:

a & b.    in 1 sec the object reaches a maximum height of 16 feet

c.      2 sec. the object will hit the ground

Step-by-step explanation:

h = -16t^{2} +32t.

When graphed, you would get a parabola that opens down.  The vertex is the key to the problem.  The vertex (t, h) will give you the maximum height and the time to reach that height.

So,  t = -b/2a = -32/-16(2) = 1

      h(1) = -16(1^{2}) + 32(1) = -16 + 32 = 16

Therefore, the vertex is (1, 16)

So, in 1 sec the object reaches a maximum height of 16 feet

let h = 0 for when the object hits the ground

-16t^{2} +32t = 0

-16t(t - 2) = 0

t = 0  or t = 2

After 2 sec. the object will hit the ground

Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?​
Serga [27]

Answer:

No, They are not equivalent

Step-by-step explanation:

The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.

The variable in this question is x.

To prove this, we equate both expressions:

10x + 6 = 5x + 11

10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1

This shows that they have the same value ONLY when x is 1.

This is why Andre says that they are equivalent, but they are not.

Find the area of the trapezoid by decomposing it into other shapes. A) 48 cm2 B) 55 cm2 C) 66 cm2 D) 96 cm2
snow_tiger [21]

Answer:

The answer is B.

Step-by-step explanation:

You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :

area =  \frac{1}{2}  \times (a + b) \times h

let \: a = 6,b = 16,h = 5

area =  \frac{1}{2}  \times (6 + 16) \times 5

area =  \frac{1}{2}  \times 22 \times 5

area = 11 \times 5

area = 55 \:  {cm}^{2}
