Step-by-step explanation: you have to use the formula base times height divided by 3 please mark me the branliest
Answer:
9feet
Step-by-step explanation:
Given the path of the toy modeled by the function f(x)=−x^2+4x+5, where x is the number of feet the toy is from Emmy and f(x) is the height of the toy.
AT maximum height, the velocity of the toy will be zero. Hence;
df(x)/dx = 0
-2x + 4 = 0
-2x = -4
x = -4/-2
x = 2
Get the maximum height;
Substitute x = 2 into the given function;
f(x)=−x^2+4x+5
f(2)=−2^2+4(2)+5
f(2) = -4+8+5
f(2) = 9feet
Hence the maximum height of the toy is 9feet
Can you please explain what question you have?
8 and 9 because 8 x 8= 64 and 9 x 9 = 81. Between 64 and 81 is 75.
Answer:
- t = 2.7 seconds
- t = 4.9 seconds
Step-by-step explanation:
<h3>Given </h3>
Function
<h3>To find</h3>
- Value of t when s(t) = 213
<h3>Solution</h3>
- 213 = -16t^2 + 122t
- 16t^2 - 122t + 213 = 0
- t = (122 ± √(-122)² -4*16*213)/2*16
- t = (61 ± √313)/16
- t = 2.7 seconds, t = 4.9 seconds
