find the volume of the cylinder formed when the rectangle in the figure is rotated about the x-axis.
A. 62.83 units
B. 157.08 units
C. 314.15 units
D. 31.42 units
Answer:
A
Step-by-step explanation:
that means the radius of the left and right circles is 2 units.
and the height of the cylinder is 5 units.
the volume of a cylinder is calculated by first standing it upright on one of the circles, and then the volume is ground area times height.
the area of a circle is pi×r².
so the volume here for us is then
pi×2²×5 units = pi×4×5 = pi×20 = 62.83185307... units
and that makes A the correct answer.

Which bowl holds more water if it is filled to a depth of four units?
The hyperboloid z= √(1+x^2+y^2) for 1≤ z ≤ 5
The answer is: The hyperboloid holds more water with a volume of [112π/3]
I just need an explanation!!
5 stars and marked the brainiest if the explanation is done well!!
paraboloid: v = ∫[0,4]πz dz = 8π cone:
v = ∫[0,4]πz^2 dz = 64/3 π
hyperboloid: v = ∫[1,5]π(z^2-1) dz = 112/3 π
when you see that the cone's radius at the top of the water is √8, while the paraboloid's is only 2.
hope it helps.
The lunch lady pushes a 100 kg zombie with 300 N of force. How much is the zombie accelerated? How do you solve is is division or multiplication
Step-by-step explanation:
Use Newton's second law. Force equals mass times acceleration.
F = ma
300 N = (100 kg) a
a = 3 m/s²
My father’s monthly salary is twice what my mother makes in a month. Their combined salary is P27,000
Please help !
Step-by-step explanation:
mother salary: x
father salary:2x
total salary =27000
therefore 3x=27000
so x=900 (divided by 3)
therefore mother salary = 900
father salary=2multiplied by 900=1800
Answer:
Father's monthly salary is P18,000
Mother's monthly salary is P9,000
Step-by-step explanation:
The problem above can be solved by using "algebraic expressions."
Let x be the father's monthly salary
Let y be mother's monthly salary
Formula: x + y = P27,000
If father's monthly salary is twice than what mother makes, then: x = 2y, which means,
2y (father's salary) + y (mother's salary) = P27,000
First step: 2y + y = P27,000
Second step: 3y = P27,000
Third step: y = [tex]\frac{P27,000}{3}[/tex]
Fourth step: y = P9,000
So, mother's salary is P9,000. This means we can get father's salary:
2y = 2 × P9,000 = P18,000 (this is the value of x)
So, father's salary is P18,000.
If we combine both of their salaries, the product is P27,000.
x + y = P27,000
P18,000 + P9,000 = P27,000
So, this explains the answer.

Step-by-step explanation:
M stands for one thousand
C stands for one hundred
C stands for one hundred
C stands for one hundred
XL stands for forty
Answer:
1340
Step-by-step explanation:
M = 1000
C = 100, since he have 3 C's, it becomes 300
L = 50

The first term of geometric series is, a = 363/82
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Give that;
Sum of T₃ and T₇ of geometric series = 3267
And, common ratio(r) = 3
Hence, To find first term (a) we can use formula as;
Tₙ = arⁿ⁻¹
Now, put the value on formula;
T₃ = a(3)³⁻¹
T₃ = (3)²a
And, T₇ = a(3)⁷⁻¹
T₇ = (3)⁶a
Since, T₃ + T₇ = 3267
Hence,
(3)²a + (3)⁶a = 3267
3²(a + 3⁴a) = 3267
(a + 3⁴a) =363
a + 81a = 363
82a = 363
a = 363/82
Thus, The first term of geometric series is, a = 363/82

what is the slope of a line parallel 18x+15y=90
Answer:
-6/5
Step-by-step explanation:
Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
Answer:
[tex]\displaystyle -1\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\displaystyle 18x + 15y = 90 \hookrightarrow \frac{15y}{15} = \frac{-18x + 90}{15} \\ \\ \boxed{y = -1\frac{1}{5}x + 6}[/tex]

Consider the [tex]n[/tex]-th partial sum of a geometric series with first term [tex]a[/tex] and common ratio [tex]r[/tex] between consecutive terms. Then the sum of the first [tex]n[/tex] terms of this series is
[tex]S = a + ar + ar^2 + \cdots + ar^{n-1}[/tex]
Multiply both sides by [tex]r[/tex], then subtract [tex]rS[/tex] from [tex]S[/tex] and solve for [tex]S[/tex].
[tex]rS = ar + ar^2 + ar^3 + \cdots + ar^n[/tex]

3. A playground designer wanted to place a fountain so that it was close to both the slide and the swings.
Refer to the coordinate grid shown. Each unit on the grid represents 5 ft.
(a) Find the distance from the fountain to the slide. Show your work.
Answer:
10ft
Step-by-step explanation:
Hi! Thanks for using Brainly! My work and explanation is shown below!
Equation Used to Solve:
5x
Solve:
5(2)=10
The slide is 10ft away from the fountain since each unit equal 5 ft, each increase by 1 on the y-value is 5ft, and each increase by 1 on the x-axis is 5ft, meaning that if the slide is at (-2, 0) and the fountain is at (-2, -2) there was an increase of 10ft total.
A train ride is 8 hours long every 2/3 hours the conductor checks on the passengers how many times during the trip does he check on the passenger Please show work
Answer:
The conductor checked on the passengers 12 times.
Step-by-step explanation:
To find how many times the conductor checks on the passengers, you must do
8 divided by 2/3
because you have to find how many 2/3 (times checked by conductor) are in 8 hours.
8/1 ÷ 2/3
Switch the two numbers of 2/3 or find the reciprocal which is
3/2
and change ÷ to ×
Now solve.
8/1 x 3/2 = 24/2 (8x3=24 and 1x2=2)
which Simplified is
12/1 or 12
Check your answer:
12/1 x 2/3 = 24/3 = 8
The conductor checked on the passengers 12 times.

Assuming the data is normally distributed, approximately what percent of
customers are willing to pay between $1.30 and $1.70 for a pint of frozen
yogurt?
T
9514 1404 393
Answer:
95%
Step-by-step explanation:
The given limits differ from the mean by ...
1.30 -1.50 = -0.20
1.70 -1.50 = 0.20
These values are 2 × the standard deviation of 0.10. The 68-95-99.7 rule tells you that 95% of the population lies within 2 standard deviations of the mean.
For this question, that means 95% of customers are willing to pay between $1.30 and $1.70.

A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile. If the total cost of hiring a vehicle on one occasion is 170, how many miles were driven
Answer:
85
Step-by-step explanation:
Because 170 divided by 2.
The number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.
Let x be the total number of miles:
From the question:
y be the total cost of hiring
y = 20 + 2x
y = 170
170 = 20 + 2x
150 = 2x
x = 150/2
x = 75 miles
Thus, the number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.
