Point C is between points A and B on Find the missing length. AC = 12, AB = 34, CB = _____ a. 29 c. 28 b. 22 d. 32
JulsSmile [24]
Length of CB = Length of AB -AC
= 34 - 12 = 22
therefore the answer will be b.22

Learning task 1: find the value of the expression given the value of the variables 3x + 5 x = 2 5xy + x - 4 , x = -3 and y = 5
olasank [31]

Step-by-step explanation:

3x+5x=25xy+x-4

8x=25xy+x-4

8(-3)=25(-3)(5)+(-3-4)

-24=25(-15)+(-7)

-24= -375-7

-24= -382

if the question is right that you asked, i mean the = sign then the solution is will be come like this but if there is no = sign then you can get the solution by subtracting -24-382= -406

The following function represents the profit P(n), in dollars, that a concert promoter makes by selling tickets for n dollars ea
Gre4nikov [31]
A) zeroes

P(n) = -250 n^2 + 2500n - 5250

Extract common factor:

P(n)= -250 (n^2 - 10n + 21)

Factor (find two numbers that sum -10 and its product is 21)

P(n) = -250(n - 3)(n - 7)

Zeroes ==> n - 3 = 0  or n -7 = 0
Then n = 3 and n = 7 are the zeros.

They rerpesent that if the promoter sells tickets at 3  or 7 dollars the profit is zero.

B) Maximum profit

Completion of squares

n^2 - 10n + 21 = n^2 - 10n + 25 - 4 = (n^2 - 10n+ 25) - 4 = (n - 5)^2 - 4

P(n) = - 250[(n-5)^2 -4] = -250(n-5)^2 + 1000

Maximum ==> - 250 (n - 5)^2 = 0 ==> n = 5 and P(5) = 1000

Maximum profit =1000 at n = 5

C) Axis of symmetry

Vertex = (h,k) when the equation is in the form A(n-h)^2 + k

Comparing A(n-h)^2 + k with - 250(n - 5)^2 + 1000

Vertex = (5, 1000) and the symmetry axis is n = 5.
