The volume of the cylinder is ?
The volume of a cylinder with the same radius and double the height is ?
Answers
Answer:
Step-by-step explanation:
The volume of the original cylinder = pi * r^2 * h
Givens
r = 6 in
h = 3 in
pi = 3.14
Solution
V = pi * r^2 * h
V = 3.14 * 6^2* 3
V = 3.14 * 36 * 3
V = 339. 12
Part 2
If you double the height, you will double the volume
V = 3.14 * 36 * 6
V = 678.24

BAC rounded to 3 SF.
Answers
Step-by-step explanation:
I am not sure if I understand you right about what is needed.
I would understand we need the angle BAC (at A).
first of all, this is a right-angled triangle.
Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (side opposite of the 90° angle).
in our case that means
AC² = x² + y² = 4² + 6² = 16 + 36 = 52
AC = sqrt(52)
now we can use the law of sine to get the other angles.
a/sin(A) = b/sin(B) = c/sin(C)
with the sides and the corresponding angles being opposite.
in our case
y/sin(A) = AC/sin(B) = AC/sin(90) = AC
sin(A) = y/AC = 6/sqrt(52) = 0.832050294...
the angle A = 56.30993247...° ≈ 56.3°

(x2 - 1) - 5(x - 1)
(x2 - 1) - 5x-1

x^2 -1 - 5(x-1)
Step-by-step explanation:
p(x) = x^2 - 1 and q(x) = 5(x - 1)
p(x) - q(x) = x^2 - 1 - ( 5(x-1))

Answers
Radius = 14 : 2 = 7 in.
Area = 7 x 7 x 3.14 = 153.86 (in2)
Answer:
153.86 in²
Step-by-step explanation:
Before finding the area of the circle, first, let us find the radius.
d = 2r14 = 2r
Divide both sides by 2.
7 in = r
And now let us find the area of the circle.
Area = π r²= 3.14 × 7 × 7
= 21.98 × 7
= 153.86 in²

D. Replace y with f1(x).
Answers
Answer:A
Step-by-step explanation:
The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.
What is a Function?A function is a law that relates two variables namely, a dependent and an independent variable.
A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.
The function is f(x) = 2x -1
The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.
Patel replaced f(x) by y, y = 2x -1
He then switched x and y, x = 2y -1
The next step is to solve the equation for y.
2y = x +1
y = (x +1) /2

According to this equation, how much will/did people in the U.S. Spend on statins in the year 2005? Answer: People in the U.S. Will spend billion dollars on statins in 2005.
Answers
Answer:
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.
Step-by-step explanation:
Given:
S − 1.9x = 4.9
Where,
S = sales of statin in billions of dollars
x = years after 1998
how much will/did people in the U.S. Spend on statins in the year 2005?
2005 is a year after 1998
Number of years = 2005 - 1998
= 7
x = 7 years
S − 1.9x = 4.9
S - 1.9(7) = 4.9
S - 13.3 = 4.9
Add 13.3 to both sides
S = 4.9 + 13.3
= 18.2
People in the U.S. Will spend 18.2 billion dollars on statins in 2005.
