Answer:
Hi.
Step-by-step explanation:
Because this question is asking how much water the water tower can hold, it's asking for the volume of a cylindrical figure. Let's use this formula:
V
=
π
r
2
h
First, let's find our variables by plugging in our information.
r
=
(
1
2
)
d
r
=
(
1
2
)
20
r
=
10
h
=
24
V
=
π
(
10
2
)
(
24
)
Following PEMDAS (Parentheses, Exponents, Multiply, Divide, Add, Subtract), we'll find
(
10
2
)
first.
V
=
π
(
100
)
(
24
)
Now, multiply (100) and (24):
V
=
π
(
2400
)
V
=
2400

Answer:
55
Step-by-step explanation:
Lucas went to the bank the first time with $55 and the second time with $55, when you add those togeother you get $110. Then he wrote a check for $116 and ended up having -$6...basically if you have $110 in all then you write a check for $116 you would have -$6 in your balance. 110-116 = -6
Vertex: V=(-2,-3)=(h,k)→h=-2, k=-3
The parabola is horizontal, then its equation has the form:
x=a(y-k)^2+h
x=a(y-(-3))^2+(-2)
x=a(y+3)^2-2
When the y-value is -2, the x-value is -5:
-5=a(-2+3)^2-2
-5=a(1)^2-2
-5=a(1)-2
-5=a-2
-5+2=a-2+2
-3=a
a=-3
Answer: The coefficient of the squared term in the parabola's equation is a=-3
Answer: Option D. -3
