Answer:
8/15
Step-by-step explanation:
H=-16t² +v(0)t+h(0)
v(0)=192
h=-16t² +192t+h(0)
h(0) should be 0, because the mortar sits on the ground.
h= - 16t²+192t
This function will have maximum because it has minus before x², and parabola is looking down.
h=-(16t²-192t)=-(16t² -2*4t*24+24²)+24²
h=-(4t-24)²+24²
h=-(4t-24)²+576
vertex (24 feet, 576 feet)
24 feet horizontally from the mortar and 576 feet up
The value of the expressions (-0.3)⁴ equal to 0.0081.
<h3>What is a mathematical expression?</h3>
A mathematical expression is the representation of numbers in the form of powers or mathematical signs.
Here we have the (-0.3)⁴
Now by evaluating the expression we will get:
(-0.3)⁴=(-0.3x-0.3x-0.3x-0.3)
Hence the value of the given expression will be 0.0081
