Let the coordinate of P be (x, y), then
(x, y) = ((44(8) + 11(3))/(11 + 44), ((44(0) + 11(-2))/(44 + 11)) = ((352 + 33)/55, -22/55) = (7, -0.4)
The coordinates of P are (7, -0.4)
The inverse of F(X) is a function.
For something to be a function, a vertical line must not intersect the graph more than once. Since, the horizontal line doesn't intersect the F(X) graph twice, this means that the vertical line won't intersect with the inverse of the graph
Answer:
- √7
Step-by-step explanation:
√63 = √9*7 = √9*√7
Sqrt(9) = 3
3√7 - 4√7 = -1√7= -√7
Answer:
New height = 6
Step-by-step explanation:
The water is going to be the same volume no matter how the tank is orientated.
So you can do this 2 ways.
First way
Find the volume in the tank when the water goes up 24 cm on the height.
V = L*W*h
L = 8
W = 10
H = 24
V = 1920 cm^3
Now do it using the
L = 40
W = 8
h = ?
1920 = L * W * h
1920 = 40 * 8 * h
1920 = 320 * h
h * 320 = 1920
h = 1920/320
h = 6
Or you can do it without finding the 1920
L*W*h = L1 * w1 * h1
8*10*24 = 40 * 8 * h The 8's cancel
10*24 = 40*h Divide both sides by 10
24 = 4h Divide by 4
h = 6
Same as you got before.
