The function f(x) = –x2 + 60x – 116 models the monthly profit, in dollars, a shop makes for repairing windshields, where x is th

Sholpan [36]

Answer:

A. We factor the equation to get: -(x-25)^2+361 In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.

Step-by-step explanation:

f(x)=−(x2−60x+900−900)−116

f(x)=−(x−30)2+784

Maximum Profit=784

Vertex is (30, 784)

maximum profit is when x wind-shields are repaired.

−x2+60x−116=0

x2−60x+116=0

x2−2x−58x+116=0

x(x−2)+58(x−2)=0

(x−2)(x−58)=0

x=2,58

x intercepts are x=2, x=58

at these points there is no profit or loss.

Evaluate the function <br><br> f(x)=−4x^2+6x−4 <br><br> Find f(5)

Tamiku [17]

Hey there!

1. How to find f(5)?

To find f(5) - simply substitute x = 5 in the function. f(5) means the value of f(x) at x = 5.

2. Substitution and Evaluate

$\large{f(5) = - 4( {5})^{2} + 6(5) - 4}$

Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.

$\large{f(5) = - 4(25) + 30 - 4} \\ \large{f(5) = - 100 + 30 - 4} \\ \large{f(5) = - 74}$

3. Final Answer

f(5) = -74

Help Please on this question

Anika [276]

Answer:

See below

Step-by-step explanation:

According to triangle mid-segment theorem:

c) CT = 1/2 EN

Given that EN = 43

=> CT = 1/2 (43)

=> CT = 21.5

a) AE = 2PT

Since PT = 13

=> AE = 2(13)

=> AE = 26

b) AN = 2CP

Given that CP = 29

=> AN = 2(29)

=> AN = 58

d) Perimeter of AEN = AE + EN + AN

P = 26 + 43 + 58

P = 127

$\rule[225]{225}{2}$

Hope this helped!
