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
Answer:
<u>The correct answer is B. 9</u>
Step-by-step explanation:
Let's solve for y in the equation below, given that x = 2
y = 6x - 3
Substituting x in the equation, this way:
y = 6 * 2 - 3
y = 12 - 3
y = 9
The value of y is 9 when x is 2
<u>The correct answer is B. 9</u>
The answer is the second answer choice, an = -13 + 5(n - 1)
