Answer:
h = 5 or h = 3
Step-by-step explanation:
f(x)=(x-h)^2 is a parabola
The vertex of a parabola is its lowest or highest point.
So (4,1) is a point on f(x)
substituting into the new equation, 1 = (4-h)^2
4-h = 1 or 4-h = -1
h = 5 or h = 3

Step-by-step explanation:
x² + 16x + 64 = (x + 8)². Hence p = 8.
Since (x + 8) is a factor of 4x² + 37x + k,
4(-8)² + 37(-8) + k = 0. (by Factor Theorem)
=> 256 - 296 + k = 0
=> k - 40 = 0
=> k = 40.
The value of k is 40.
Answer:
One marble (other than red)
Step-by-step explanation:
The total number of marbles is 15 + 18 + 6 + 10 = 49. The probability of drawing a red marble is 10 out of 49. We want to change those odds to 10 out of 50 (or 20%). Therefore, we need to add <em>one</em> marble; any color other than red will work.
