Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
Answer:
the relation between them are
n(U) = n(X U Y) + n(xūy).
It would be .345% because to change it to a percent all you have to do is move the decimal point two places to the right.
Answer:
(2.5, 4 )
Step-by-step explanation:
Using the midpoint formula
Given endpoints (x₁, y₁ ) and (x₂, y₂ ), then midpoint is
[0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]
Given
(0, 1) and (5, 7), then
midpoint = [ 0.5(0 + 5), 0.5(1 + 7) ] = (0.5(5), 0.5(8)) = (2.5, 4)
Well, 1x5=5 and 2x5=10 so 3x5=15
