A)
Vertex:(3,0)
x-intercepts: (3,0)
y-intercepts: (0,27)
B)
Vertex:(0,-9)
x-intercepts:none
y-<span>intercepts:</span> (0,-9)
You have to multiply 972 times 1/3 which would be 324 so your answer is 324πcm³
Answer:
red and blue are not a Selection!!!!!
Given from the question
Vertex
(h,k) = <span>(500, 15900)
One of the points on the graph
(x,y) = (0,8400)
FIRST PART: Find the quadratic function
We can find the quadratic function by this formula
y = a (x - h)</span>² + k
Input the numbers to the formula, to find the value of a
y = a (x - h)² + k
8400 = a(0 - 500)² + 15900
8400 = a (500)² + 15900
8400 = 250000a + 15900
-250000a = 15900 - 8400
-250000a = 7500
a = 7500/-250000
a = 0.03
Submit a to the formula
y = a (x - h)² + k
y = 0.03 (x - 500)² + 15900
<em>(This is the quadratic function)
</em>SECOND PART: Find the linear function
<em />the total cost = cost each helmet × the number of helmet
y = 26x
SO, THE ANSWER IS OPTION B
Answer:
No. It is a constant function.
Step-by-step explanation:
The function f(x) = e^2 is not an exponential functional. Rather, it is a constant function. The reason for this is that in f(x) = e^2, there is no x involved on the right hand side of the equation. The approximate value of e is 2.718281, and the approximate value of 2.718281^2 is 7.389051. This means that f(x) = e^2 = 7.389051. It is important to note that for any value of x, the value of the function remains fixed. This is because the function does not involve the variable x in it. The graph of the function will be a line parallel to the x-axis, and the y-intercept will be 7.389051. For all the lines parallel to x-axis, the value of the function remains the same irrespective of the value of x. Also, the derivative of the function with respect to x is 0, which means that the value of the function is unaffected by the change in the value of x!!!
