Answer:
Problem 1 = 9
Problem 2 = 260
Step-by-step explanation:
Answer:
V = 19.625h
Step-by-step explanation:
Volume of a cylinder V = πr²h
r is the radius
h is the height
Given
r = base/2
r= 5/2
r= 2.5
Substitute into the formula
V = π(2.5)²h
V = 3.14*6.25h
V = 19.625h
hence the required expression is V = 19.625h
Hi
5x²-x-4 = 0
Δ= (-1)² - 4*5*(-4)
Δ = 1 -4*-20
Δ = 1 +80
Δ = 81
√Δ= 9
as Δ ≥ 0 , so 2 solutions exist in R
S1 is : ( 1+9) /2*5 = 10/10 = 1
s2 = (1 -9)/2*5 = -8/10 = -4*2 /2*5 = -4/5
Corrects answers are A and D
Answer:
9
Step-by-step explanation:
the line hits the y-axis at the point (0, 9) where x=0 meaning this point is the y-intercept being 9
