Answer:
21.V=1746.1
22.V=1922.7
23.V=54.4
Step-by-step explanation:
V=h*w*l V=pir^2*h
V=12*8*14 . V=pi*4^2*8
V=1344 . V=402.1
V1+V2=1344+402.1=1746.1
V=pi*r^2*h V=2/3*pi*r^3
V=pi*6^2*13 V=2/3*pi*6^3
V=pi*36*13 V=2/3*pi*216
V=1470.3 V=452.4
V1+V2=1470.3+452.4=1922.7
V=1/3pi*r^2*h V=1/3pi*r^2*h
V=1/3pi*2^2*6 V=1/3pi*2^2*7
V=8pi V=28/3pi
V=25.1 . V=29.3
V1+V2=25.1+29.3=54.4

Solve the equation x^2 - 16x+ 54 = 0 by completing the square.
Fill in the values of a and b to complete the solutions.
Answer:
[tex]x = 8\±\sqrt{10[/tex]
[tex]a =8[/tex] [tex]b = 10[/tex]
Step-by-step explanation:
Given
[tex]x^2 - 16x + 54 = 0[/tex]
Required
Complete the square
[tex]x^2 - 16x + 54 = 0[/tex]
Subtract 54 from both sides
[tex]x^2 - 16x + 54 -54= 0-54[/tex]
[tex]x^2 - 16x = -54[/tex]
--------------------------------------------------
Take half of - 16
[tex](-16/2) = -8[/tex]
Square the result
[tex](-8)^2 = 64[/tex]
Add the squared result to both sides of the equation
--------------------------------------------------
So, we have:
[tex]x^2 - 16x +64= -54+64[/tex]
[tex]x^2 - 16x +64= 10[/tex]
Expand
[tex]x^2 - 8x - 8x + 64 = 10[/tex]
Factorize
[tex]x(x - 8) - 8(x - 8) = 10[/tex]
Factor out x - 8
[tex](x - 8)(x - 8) = 10[/tex]
[tex](x - 8)^2 = 10[/tex]
Take square roots
[tex]x - 8 = \±\sqrt{10[/tex]
Solve for x
[tex]x = 8\±\sqrt{10[/tex]
We have:
[tex]x = a - \sqrt{b}[/tex]
[tex]x = a + \sqrt{b}[/tex]
By comparing the above with: [tex]x = 8\±\sqrt{10[/tex]

Find the volume of a cylinder prism with radius of 3 and height of 11
Answer:
310.86
Step-by-step explanation:
so V=Bh
and B=pi *r^2
so that means 3.14*9 (since 3^2 is 9)
3.14*9=28.26
then 28.26*11= 310.86
A railroad tunnel is shaped like a semiellipse, as shown below.
A semiellipse is shown on the coordinate plane with vertices on the x axis and one point of intersection with the positive y axis.
The height of the tunnel at the center is 35 ft, and the vertical clearance must be 21 ft at a point 8 ft from the center. Find an equation for the ellipse.

A popular internet subscription service for movies, TV series, and documentaries conducts a survey in which it randomly samples 1,000 of its customers. The survey asks the customers which way they use their streaming service the most: (1) watching movies, (2) watching TV series, or (3) watching documentaries. They also ask the level of satisfaction with the service they most often use (on a scale of 0 to 10 with 0 very poor and 10 excellent). Is there statistical evidence for this internet subscription service that the mean satisfaction differs between customers who watch movies, TV series, or documentaries the most?

URGENT!! PLS HELP 16 students are competing an art contest in how many different ways can students finish first second and third
Help plz I would appreciate it so much.
Answer:
B
Step-by-step explanation:
Choose a point from your graph. I chose (2, 1). Then substitute the x value into each of the equations. The second equation says that the y value (1 in the point I chose), is half of the x value (2 in the point I chose). Since 1 is half of 2, B is the correct equation :)
50 POINTS. A ball is thrown into the air from a height of 4 feet at time t = 0. The function that models this situation is h(t)= -16t^2 + 64t + 4, where t is measured in seconds and h is the height in feet. What domain makes sense for this function
Answer:
The domain that makes sense for this function is all values greater than or equal to 0.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time t = 0. It is modeled by the function:
[tex]h(t)=-16t^2+64t+4[/tex]
The domain of the function is time t. The range of the function is the ball's height in the air h.
Since time is our domain, we must restrict our domain to values equal to or greater than 0 since time cannot be negative.
Therefore, the domain that makes sense for this function is all values greater than or equal to 0.
In interval notation, this is:
[tex][0, \infty)[/tex]
And as an inequality:
[tex]t\geq 0[/tex]

Find the median of the set of data. 30, 16, 49, 25
Answer:
16,25,30,49
25+30=55
55÷2=27.5
Step-by-step explanation:
median means the middle value of any set of data so first arrange the data into ascending order.
16, 25, 30, 49
the data is even so we take both the middle value , add it and divide it with 2
25+30=55
55÷2=27.5

Write the equation of a circle whose center is (-2, 0) and has the point (-5,-6) on its circumference.
Answer:
(x+2)^2 + y = √45 ^2
Step-by-step explanation:
this should be right
Answer:
[tex](x + 2)^{2} + y^{2} = 45[/tex]
Step-by-step explanation:
The radius (r) of the circle is the distance between (-2, 0) and (-5, -6)
r = [tex]\sqrt{(-2 + 5)^{2} + (0 + 6)^{2} } = \sqrt{3^{2} + 6^{2} } = \sqrt{9 + 36} = \sqrt{45}[/tex]
[tex]r^{2}[/tex] = 45
[tex](x + 2)^{2} + y^{2} = 45[/tex] is the equation of the circle
