(1, 2)
(0, 1)
(0, -7)
(-1, -2)

C. 1080 units 3
D. 360 units 3
hello,
here is your answer:
**********
volume of cylinder = [tex]\pi[/tex]r²h
radius = 12 units
height = 15 units
volume = r² × h × [tex]\pi[/tex]
= 12² × 15 × [tex]\pi[/tex]
= 144 × 15 × [tex]\pi[/tex]
= 2160 × [tex]\pi[/tex]

The volume of cylinder is 2160 [tex]units^{3}[/tex].
What is volume?Volume is the measure of the capacity that an object holds.
What is the formula for the volume of cylinder?The formula for the volume of cylinder is
[tex]v = \pi r^{2}h[/tex]
Where,
V is the volume of cylinder.
r is the radius of cylinder.
h is the height of cylinder.
π = 3.14
According to the given question
Height of the cylinder, h = 15 units
Radius of the cylinder, r = 12 units
Therefore, the volume of the cylinder is given by
[tex]v = \pi (12)^{2}(15)[/tex]
v = π × 144 × 15
V = 2160π [tex]units^{3}[/tex]
Hence, the volume of cylinder is 2160 [tex]units^{3}[/tex].

Determine the angle at the centre of a circle with radius 12.0 cm for an arc length of of 21.0 cm.
A. 4/7 radians
B. 7/π radians
C. 7/4 radians
D. 7 π/4 radians
Answer:
[tex]\theta=\dfrac{7}{4}\ \text{radian}[/tex]
Step-by-step explanation:
We have,
Radius of the circle is 12 cm
Arc length, l = 21 cm
It is required to find the central angle of the circle. The formula for the length of an arc of a circle is :
[tex]l=r\times \theta[/tex]
[tex]\theta[/tex] is central angle
[tex]\theta=\dfrac{l}{r}\\\\\theta=\dfrac{21}{12}\\\\\theta=\dfrac{7}{4}\ \text{radian}[/tex]
So, the angle at the centre of the circle is [tex]\dfrac{7}{4}\ \text{radian}[/tex].
Two people swing a jump rope. The highest point in the middle of the jump rope is 76 inches above the ground, and the lowest point is 4 inches. The rope makes 4 revolutions per second. Write a model for the height of the rope in inches as a function of time in seconds given that the rope starts at its lowest point.
Answer:
h(t) = 36sin(1440x)+ 40
Step-by-step explanation:
Given the information:
highest point: 76 inches=>lowest point: 4 inches => 4 revolutions per second => period: [tex]\frac{1}{4}[/tex] per second = [tex]\frac{360}{\frac{1}{4} } =1440[/tex]y = a sin (bx+c) + k for different values of a, b, and c
=> Amplitude (a) = (highest point - lowest point) / 2 = 36
=> asymptom (k) = (highest point - lowest point) / 2 = 40
=> model for the height of the rope in inches as a function of time in seconds given that the rope starts at its lowest point is:
h(t) = 36sin(1440x)+ 40
Hope it will find you well.

Marco needs to make a five letter password, without repeating any letters. How many different passwords could Marco make?
A.) 120
B.) 5,640,000
C.) 7,893,600
D.) 11,881,376
Answer:
7,893,600
Step-by-step explanation:
Permutations
n = possible things used (26 letters)
r = how many at a time (5 at a time - this is without repeating)
nPr = n! / (n - r)!
26P5 = 26! / (26 - 5)!
26! = 26 x 25 x 24 x 23 x 22... = 403291461126605635584000000
(26 - 5)! = 21! = 51090942171709440000
An easy hack for solving division of large factorials is to use canceling.
26!/21! = 26 x 25 x 24 x 23 x 22 (because 21 down to 1 is cancelled by 21!)
= 7,893,600

Answer:
y = -3
Step-by-step explanation:
-3(y-5) = 24
Divide each side by -3
-3(y-5)/-3 = 24/-3
y - 5 = -8
Add 5 to each side
y-5+5 = -8+5
y = -3
Answer:
y= -3
Step-by-step explanation:
-3(y-5)= 24
Do distributive property so, -3y + 15= 24
Subtract 15 from both sides so, -3y + 15 - 15= 24 - 15
Divide -3 from both sides to leave y on one side so, -3/-3y= 9/-3
The answer would be y= -3.

Set up an equation to solve for y
Answer:
The red answer choice
Step-by-step explanation:
Since the sine of an angle is the length of the opposite side divided by the length of the hypotenuse:
[tex]\sin 43=\dfrac{y}{25}[/tex]
Therefore, the correct answer is red. Hope this helps!
Answer:
sin 43 = y / 25
Step-by-step explanation:
sin theta = opposite / hypotenuse
sin 43 = y / 25
Multiply each side by 25
25 sin 43 = y
Samantha sells two types of wristbands, rope or beaded. She charges more for beaded wristbands than for rope wristbands. The amount of money, in dollars, that she collects from selling x wristbands of one type and y wristbands of the other type can be modeled by the expression 5x+8y.
What does the variable y represent in this situation?
A. the selling price of one rope wristband
B. the number of rope wristbands sold
C. the number of beaded wristbands sol
D. the selling price of one beaded wristband
Answer:
C
Step-by-step explanation:
Because the beaded wristbands cost more than the regulars, the 5 and 8 must refer to how much each type of wristband costs. And because y has the greater coefficient of 8, y must represent the number of beaded wristbands sold, or C. Hope this helps!

The length of a rectangle is 1 less than twice the width. Write the equation that could represent the area of the rectangle in terms of the width
Answer:
(W2-1)xW
Step-by-step explanation:
The beginning of the equation represents the length as the question states it is one less than twice the width. Because you need to multiply width and length to get area, you place the length equation and parentheses and multiply the answer to the equation by the width :) Hope this helps!
Based on the problem statement, we have a word problem before us, that is solving for the area of a rectangle with given sides.
Area = 2y^2-y
Given data
Let the Length of the rectangle be x
and let the width be y
From the statement "The length of a rectangle is 1 less than twice the width"
the length can we re-written as
x = 2y-1
We know that the area of a rectangle is
Area = Length*Width
Area = (2y-1 )* y
Area = 2y^2-y
hence the expression for the area is given as 2y^2-y

Find the value of x in each case:
Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ FEB and ∠ DEB are adjacent angles and supplementary, thus
∠ FEB = 180 - 4x , so
180 - 4x + x = 147, that is
180 - 3x = 147 ( subtract 180 from both sides )
- 3x = - 33 ( divide both sides by - 3 )
x = 11

Josh wanted to buy a new shirt for a school dance. At the store, he couldn't decide between a
purple plaid shirt and a scarlet striped shirt. Since the shirts were on sale for $19.95 each,
Josh decided to buy them both. He saved a total of $9.10. If he saved the same amount on
each shirt, what was the original price of each one?
Answer:
$24.50
Step-by-step explanation:
9.10/2=4.55
4.55+19.95=24.50
Answer:
24.5
Step-by-step explanation:
divide 9.10 to get half/2 numbers which is 4.55 then add 4.55 to 19.95 which is 24.5. which means each shirt was $24.5

-3x + 4 = -8
Does anyone know what x is?
Answer:
x = 4
Step-by-step explanation:
-3x + 4 = -8
-3x = -8 - 4
-3x = -12
x = -12/-3
x = 4
Answer: x = 4
Step-by-step explanation: Move all terms that don't contain x to the right side and solve.
-3x +4 = -8
-4 -4
Subtract four from the four to cancel out and the -8.
That makes the equation -3x = -12
Then, divide by -3 by -3, then -12 divide by -3, to equal 4
