Answer:
The answer is 18/40
Step-by-step explanation:
18/40 = 9/20 = 0.45 = 45 percent
V=hpir^2
so
A:B=
4pi1^2:4pi2^2=
4pi1:4pi4=
4pi:16pi=
4:16=
1:4
the ratio of volume of A to B is 1:4
Answer:
Step-by-step explanation:
Synthetic division is one way to determine whether or not a given number is a root of the quadratic. x^2 − 12x − 20 can be rewritten as x^2 - 12x + 36 - 36 - 20, or (x - 6)^2 - 56, which does not have integer solutions:
(x - 6)^2 - 56 = 0 becomes (x - 6)^2 = 56, which works out to x - 6 = ± 2√14.
None of the possible roots suggested in this problem turns out to be an actual root.
correct response: PRIME
Answer:
(0, 3 ) and (2, 0 )
Step-by-step explanation:
To find the y- intercept let x = 0 in the equation and solve for y
y = - 1.5(0) + 3
y = 3 ← y- intercept ⇒ (0, 3 )
To find the x- intercept let y = 0 in the equation and solve for x
0 = - 1.5x + 3 ( subtract 3 from both sides )
- 3 = - 1.5x ( divide both sides by - 1.5 )
x = 2 ← x- intercept ⇒ (2, 0 )
It would have 3 solutions
if you solve the equation how it is, it give 1 solution but if you make the 1 negative you get 2 more possibilities
