Answer:
You are correct.
6 in.
Find the volume of this
Cylinder.
10 in.
cubic inches
Volume of Cylinder = ar2 x h
Use 3.14 for a.
Do NOT round your answer.
======================================================
Work Shown:
r = 6 = radius
h = 10 = height
pi = 3.14 approximately
[tex]V = \pi*r^2*h\\\\V = 3.14*6^2*10\\\\V = 1130.4[/tex]
The volume of the cylinder is approximately 1130.4 cubic inches.

This graph is from a publication of the Centers for Disease Control and Prevention (2017). The y-axis shows the percentage living with diabetes.
The Board of Directors of a medical school wants to use the trend to predict the percentage in 2020 so that they can help train enough doctors to handle the growing numbers. Use a visual estimate of the line of best fit to make a prediction. Do you think your estimated line of best fit will be accurate? Explain why or why not.
Answer:
My estimate is around 16 million cases by 2020
Step-by-step explanation:
I used the formula of rise over run
(The "Rise over Run" formula is y2-y1/x2-x1)
I used 2010's total of cases 22 million and 1960's 4 million
Now I subtract 2010 and 1960
Which is 40 or 4 in this case
Then I subtracted 22 million by 4 million which is 5.5
Round 5.5 to 6 (Since it is an estimate)
Divide 6 and 4
6/4= 1.5 which I rounded to 2 million now I start at 1960's 4 million case and add 2 million for 10 year or multiply 6 by 2 which is 12 and add it by 4 which is 16
Hence 16 million

A person places $6520 in an investment account earning an annual rate of 2.5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a nfitural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 3 years.
Given:
Principal value = $6520
Annual rate of interest = 2.5% compounded continuously.
Time = 3 years
To find:
The amount of money after three years.
Solution:
Formula for the value of the amount is:
[tex]V=Pe^{rt}[/tex]
Where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.
Putting [tex]P=6520,r=0.025,t=3[/tex], we get
[tex]V=6520e^{(0.025)(3)}[/tex]
[tex]V=6520e^{0.075}[/tex]
[tex]V=7027.80466[/tex]
[tex]V\approx 7027.80[/tex]
Therefore, the amount of money after three years is about $7027.80.

Find the area of the figure.
Answer:
A) 32.5 *but there's a typo... it's supposed to be 23.5)
Step-by-step explanation:
The area of the whole triangle is 31.5 sq. in. Then, subtracting the area of the cutout (8 sq. in.) from the triangle (31.5 sq. in.) will give you a final answer of 23.5 sq. in. I think the teacher messed up and did 32.5 instead of 23.5
A and B are both positive integers. Which expression is equivalent to - A-(-B)?
B-A
-A-B
A-B
A+B
Help
Answer: B-A
Step-by-step explanation:
We know that it is -A - (-B)
The negative sign on the A stays as it is, eliminating choices A-B and A+B.
For the sign in front of B, a double negative creates a positive. - (-B) is essentially -1 x -B, which is B. You can check this through your calculator.
Therefore, the answer is -A+B, or B-A. Hope it helps!

Answer:
I think 3cosx+2 would be g(x)
if g(x)=11x+3 find g(x+7) and g(x)+g(7).
Answer:
g(x + 7) = 11x + 80
g(x) + g(7) = 11x + 83
Step-by-step explanation:
g(x + 7) = 11(x + 7) + 3 = 11x + 77 + 3 = 11x + 80
g(x) + g(7) = 11x + 3 + 11(7) + 3 = 11x + 3 + 77 + 3 = 11x + 83
Barry's family traveled 5 7 of the distance to his uncle's house on Saturday. They traveled 1 2 of the remaining distance on Sunday. What fraction of the total distance to his uncle's house was traveled on Sunday?
Answer: [tex]\dfrac{1}{7}[/tex]
Step-by-step explanation:
Suppose total distance is [tex]x[/tex]
Distance traveled on Saturday is [tex]\frac{5}{7}[/tex] of total distance i.e.
[tex]\Rightarrow \dfrac{5}{7}\times x=\dfrac{5x}{7}[/tex]
Remaining distance is
[tex]\Rightarrow x-\dfrac{5x}{7}=\dfrac{2x}{7}[/tex]
Distance traveled on Sunday is
[tex]\Rightarrow \dfrac{1}{2}\times \dfrac{2x}{7}=\dfrac{x}{7}[/tex]
Now, the fraction of the total distance traveled on Sunday is one-seventh
[tex]\Rightarrow \dfrac{1}{7}[/tex]

I don’t know what to do
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
