C
first set up an equation
$52+8n ≥ 144
bacause she can spend 144 or less
solve 144-52=92
92/8=11.5
Answer:
(c).
Step-by-step explanation:
h(t) = - 16 t² + 80 t
Coordinates of the vertex are:
<em>t</em> = -
=
= <em>2.5 sec. </em>
<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
−4 3/7 −4 6/7 −5 3/7 4 2/7 5 1/7
Least to greatest
−5 3/7 −4 6/7 −4 3/7 4 2/7 5 1/7
Answer:
The height of the right trapezoid is 
Step-by-step explanation:
Let
x ----> the height of the right trapezoid in units
we know that
The perimeter of the figure is equal to
we have

---> because is a square
substitute
-----> equation A
<em>In the right triangle CDH</em>


so
Remember that 




so


substitute the values in the equation A
-----> equation A
