Answer:
The Volume of Cone is V=1/3hπr².
V = 1/3 × h × π × r²
V = 1/3 × 12 × 3.14 × 5cm
V = 1/3 × 12 × 15.7
V = 4 × 15.7
V = 62.8cm³ ANS
→ we need to find the radius so r = d/2 = 10/2 = 5cm

Answer:
A=259.43
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r=R/100
r=2.5/100
r=0.025 rate per year,
then solve the equation for A
A=P(1+r/n)
A=250.00(1+0.025/1)
A=250.00(1+0.025)
A=$259.43

Answers
Answer:
324 cm^3
Step-by-step explanation:
Volume = l x w x h / 2
V = 12 x 6 x 9 / 2
V = 648 / 2
V = 324 cm^3
Answer:
V = 324 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = area of triangular end × length
A of triangle = [tex]\frac{1}{2}[/tex] × 6 × 9 = 3 × 9 = 27 cm² , then
V = 27 × 12 = 324 cm³

36x + 324 = 720 find x
Answers
Answer:
x = 11
Step-by-step explanation:
First, subtract 324 from both sides:
36x + 324 = 720
36x = 396
Divide each side by 36:
x = 11
So, the answer is x = 11
Answer:
x=11
Step-by-step explanation:
first get rid of the 324 so we can leave x by itself.
324-324=0
to keep it balanced subtract it from 720
720-324=369
that leaves us with
36x=369
lastly, we have to divide both sides by 36.
36/36=0
369÷36=11
Therefore, x=11

The volume of a rectangular box with a square base remains constant at 500 cm3 as the area of the base increases at a rate of 6 cm2/sec. Find the rate at which the height of the box is decreasing when each side of the base is 15 cm long.
Answers
Answer:
the rate at which the height of the box is decreasing is -0.0593 cm/s
Step-by-step explanation:
Given the data in the question;
Constant Volume of a rectangular box with a square base = 500 cm³
area of the base increases at a rate of 6 cm²/sec
so change in the area of the base with respect to time dA/dt = 6 cm²/sec
each side of the base is 15 cm long
so Area of the base = 15 cm × 15 cm = 225 cm²
the rate at which the height of the box is decreasing = ?
Now,
V = Ah
dv/dt = 0 ⇒ Adh/dt + hdA/DT = 0
⇒ dh/dt = -hdA/dt / A
we substitute
dh/dt = [ -( 500 / 225 ) × 6 ] / 225
dh/dt = [ -(2.22222 × 6) ] / 225
dh/dt = [ -13.3333 ] / 225
dh/dt = -0.0593 cm/s
Therefore, the rate at which the height of the box is decreasing is -0.0593 cm/s

There has to be a minimum level of at least 1 subset with much more subgroups than possible, which equals at least two sets. Call for two main sub, S' and T' equivalent.
Let

What is a formula for the nth term of the given sequence? 250, 100, 40...
Answers
Answer:
The formula for the nth term of the sequence is [tex]A_n =250(\frac{2}{5})^{n-1}[/tex]
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient of consecutive terms is always the same, called common ratio.
The equation is given by:
[tex]A_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term and r is the common ratio.
250, 100, 40
First term is 250, so [tex]a_1 = 250[/tex]
Common ratio is [tex]r = \frac{40}{100} = \frac{100}{250} = \frac{2}{5}[/tex]
So
[tex]A_n = a_1q^{n-1}[/tex]
[tex]A_n =250(\frac{2}{5})^{n-1}[/tex]
The formula for the nth term of the sequence is [tex]A_n =250(\frac{2}{5})^{n-1}[/tex]

The following scatter plot represents the number of views a video gets each day.
(b) Use a graphing calculator or other technology to write a regression equation to model the data.
(c) A video is considered viral if it receives more than three million views by the time it has been posted for 10 days. Use the model from Part (b) to determine if the video will receive enough views to be considered a viral video. Show your work.
Answers
Answer:
y = 1.0535(4.9512)^x
It can be considered a viral video
Step-by-step explanation:
Using the exponential regression calculator, the regression model obtained is :
y = 1.0535(4.9512)^x
Using the model, we can determine if a video can be considered viral ;
Number of days, x = 10
y = 1.0535(4.9512)^10
y = 1.0535(8853290.1338)
y = 9,326,941.15
Hence, video will receive way over 3 million reviews, a review of about 9,326,941, hence, it can be considered a viral video.
