Answer:

72.25 ft

Step-by-step explanation:

The function that models the height of the ball is

$h(t) = 68t - 16 {t}^{2}$

The maximum height occurs at:

$t = - \frac{b}{2a}$

$t = - \frac{68}{2 \times - 16} = \frac{68}{32} = 2.125$

We substitute t=2.125 to get:

$h(2.125) = 68(2.125) - 16(2.125) ^{2}$

$h(2.125) = 72.25$

The maximum height is 72.25 feet

△ABC△ABC is similar to △XYZ△XYZ.

luda_lava [24]

Yo, im doing the same CR right now. haha
I think i have an idea on what to do.
triangles have to equal 180 degrees.
if A = 45
and C = 60
then B = 75
45 + 60 + 75 = 180.

it says the ABC is SIMILAR to XYZ.
I think they are both congruent, so ABC and XYZ have the same measurements.
that means is B = 75
then Y = 75.

i could be wrong, but thats what i think the answer would be.

A parallelogram with an equal base and height and an area greater than 64 square meters can you give me the answer please

Roman55 [17]

8
if the base and height are equal
and the formula equals b x h = A^2
then u can make a formula b x b = 64
then u take the square root of 64
