What is the constant of variation for the quadratic variation?x 2 3 4 5 6
y 20 45 80 125 180
A.5
B.10
C.15
D.25

Answers

Answer 1
Answer: Given:
x  =   2     3     4      5     6
y  = 20 ; 45 ; 80; 125;180

The constant variation for the quadratic variation is 5.

y = 5x²
y = 5(2²) = 5(4) = 20
y = 5(3²) = 5(9) = 45
y = 5(4²) = 5(16) = 80
y = 5(5²) = 5(25) = 125
y = 5(6²) = 5(36) = 180

Describe how f(x)=2 cos (πx) and g(x)=2 cos (2πx) are related.

Answers

The derivative of the natural log is 1/x, therefore the derivative is 1/cos(x). However, since the value of cos(x) is submitted within the natural log we must use the chain rule. Then, we multiply 1/cos(x) by the derivative of cos(x). We get the answer: -sin(x)/cos(x) which can be simplified into -tan(x) i

Javier has a job installing windows. He earns a rate of $75 per day plus $8 per window installed. He also receives a stipend of $25 for snacks. Javier knows his weekly earnings can be shown with the following expression:75d + 8w + 25

Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points)

Part B: If Javier works for 5 days and installs 48 windows, how much does he earn? Show your work to receive full credit. (4 points)

Part C: If Javier gets an increase in his stipend and receives $40 for snacks, would the coefficient, variable, or constant in the equation change? Why? (3 points)

Answers

Part B is 784
75 multiplied by 5 is 375
8 multiplied by 48 is 384
375 plus 384 is 759
759 plus 25 is 784
