Answer:
486 - 160l
Step-by-step explanation:
m = 90 - 32l
s = -48 + 18l
l = stationary
Combine like-terms, evaluate, then you will arrive at this crazy answer.
Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
Answer:
15 miles
Step-by-step explanation:
pythagorean theorem
9²+12²=x²
x=15 miles
Y intercept of a function can be obtained by evaluating the value of the function when x=0, i.e.
y-intercept of f(x) = f(0)
Here, f(x) = 4^(x)
so y-intercept = f(0) = 4^0 = 1
