Answer:
The constant of proportionality is 1.5 and the value of q is 9.
Step-by-step explanation:
Assume Hours as 'x' and Miles walked = 'y'
Constant of proportionality means the same value of is maintained throughout.
So, note that = 1.5
This means that should also equal 1.5.
= 9.
Therefore, the value of 'q' is 9.
Answer:
p(x) = x^4 - x^3 - 9x^2 - 11x - 4
Step-by-step explanation:
You are saying there are 3 roots of x = -1 and one x = 4 root
so...
p(x) = [(x + 1)^3 ] * (x - 4)
p(x) = (xxx + 3xx + 3x + 1 )*(x- 4)
p(x) = x^4 + 3 x^3 + 3x^2 + x - 4x^3 - 12xx - 12x - 4
p(x) = x^4 - x^3 - 9x^2 - 11x - 4
The answer would be 182
4% of 130 = 5.2
5.2 x 10yrs = 52
130 + 52 = 182
Answer: On the interval [25, 30] the function y = cos x is at it's minimum at x = 9pi or about 28.26.
The graph of y = cos x starts at 1 and moves in the shape of a wave from -1 to 1. It reaches it's first minimum value when x = pi. The period of the wave is 2 pi.
Therefore, it is at its lowest value at the following values, 1pi, 3pi, 5pi, 7pi, 9pi... The value in our given interval is 9pi.
