Answer:
The answer is D, h=3Vπr2. The height of the cone is 6 cm
Step-by-step explanation:
The Height of the Cone is 6 cm.
What is Volume of Cone?The shape's volume is equal to the product of its area and height. = Height x Base Area = Volume.
The formula for the volume of a cone is V=1/3hπr².
Given:
Volume of Cone= 1/3 πr²h
where r is the radius and h is the height.
Now, if V= 32π cm³ and r= 4 cm
Then, Volume of Cone = 1/3 πr²h
32π = 1/3 π(4)²h
32 = 1/3 (4)²h
32= 1/3 (16)h
h/3 = 2
h= 6cm
Hence, the height is 6 cm.

Internet Usage The number of hours people in the United States
spent using the Internet each year from 1998 to 2001 can be
modeled by the function f(x) 5 26.4x 1 54.4 where x is the number
of years since 1998.
a. Graph the function and identify its domain and range.
b. Find the number of hours that people spent on the Internet
in 2000. Explain how you found your answer.
c. When did people spend about 120 hours per year on the
Internet? Explain how you found your answer.
Answer:
Look in picture
Step-by-step explanation:
Functions can be represented on graph and as equation.
The domain and the range of the function are [0,3] and [54.4,133.6]The number of hours spent in 2000 is 107.2People spend about 120 hours per year in 2001The function is given as:
[tex]f(x) = 26.4x + 54.4[/tex]
(a) The graph, domain and range
See attachment for the graph of [tex]f(x) = 26.4x + 54.4[/tex]
The function represents years from 1998 to 2001.
This means that:
[tex]x = 0[/tex] in 1998 and [tex]x =3[/tex] in 2001
So, the domain is: [tex][0, 3][/tex]
From the graph;
[tex]x = 0 \to f(x) = 54.4[/tex]
[tex]x = 3 \to f(x) = 133.6[/tex]
So, the range is [tex][54.4,133.6][/tex]
(b) Number of hours spent in 2000
First, we calculate x.
[tex]x = 2000 - 1998[/tex]
[tex]x =2[/tex] i.e. 2 years since 1998
So, we have:
[tex]f(x) = 26.4x + 54.4[/tex]
[tex]f(2) =26.4 \times 2 + 54.4[/tex]
[tex]f(2) =107.2[/tex]
(c) When people starts to spend 120 hours.
We have:
[tex]f(x) = 26.4x + 54.4[/tex]
Substitute 120 for f(x)
[tex]120 = 26.4x + 54.4[/tex]
Collect like terms
[tex]26.4x = 120 - 54.4[/tex]
[tex]26.4x = 65.6[/tex]
Solve for x
[tex]x = \frac{65.6}{26.4}[/tex]
[tex]x = 2.48[/tex]
Round 2.48 to the smallest integer greater than 2.48
[tex]x = 3[/tex]
This represents the number of years, since 1998.
So, the actual year is:
[tex]Year =1998 + 3[/tex]
[tex]Year = 2001[/tex]
Hence, people spend about 120 hours per year in 2001

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?
Answer:
20
Step-by-step explanation:
7+4=11
11*5= 55
4*5=20 :)
The number of children and adults will be 35 and 20, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.
7x / 4x = constant
Then the equation is given below.
7x + 4x = 55
11x = 55
x = 11
Then the number of adults is given as,
7x = 7 (5) = 35
Then the number of children is given as,
4x = 4 (5) = 20
The number of children and adults will be 35 and 20, respectively.

Maya claims that 8n is the number of dots in figure n. Kiana claims that the number of dots in figure n is given by 4(n+1)
Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number.
Determine whether Maya, Kiana or both girls are correct in their given expressions. Justify your response.
The evaluation of your response will be based on the following criteria.
Answer:
Answer:
Kaya's answer is correct.
Step-by-step explanation:
The number of dots in successive figures are
8, 16, 24.
So Kaya's solution 8n is correct.
When n = 1, first square = 8*1 = 8 dots
n = 2: second square = 8*2 = 16
n = 3, 3rd square = 8*3 = 24.
If I have interpreted Kianna's formula correctly
for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2
= 0.

Write sec 325° in terms of the secant of'a positive acute angle.
Answer:
sec35°
Step-by-step explanation:
sec325° = sec(360 - 325)° = sec35°
The secant of a positive acute angle of sec 325° = sec 35° = 1.22077
What are Trigonometric Ratios?
Trigonometry values are all about the study of standard angles for a given triangle with respect to trigonometric ratios.The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given data ,
The trigonometric ratio is = sec 325°
Now , to express the ratio in terms of a positive acute angle , we take the four quadrants of the graph and express the angle in the first quadrant.
And , 325° lies on the 4th Quadrant , where all cosines and secants are positive.
Therefore , sec 325° = sec ( 360° - 35° )
= sec ( 35° )
=1.22077
Hence , the secant of a positive acute angle of sec 325° = sec 35° = 1.22077

a.
tons
b.
pounds
c.
kilograms
d.
grams

4x+1+3=8 ayuden manden paso a paso
Answer:
x = 1
Step-by-step explanation:
Solve for x:
4 x + 1 + 3 = 8
Hint: | Group like terms in 4 x + 1 + 3.
Grouping like terms, 4 x + 1 + 3 = 4 x + (1 + 3):
4 x + (1 + 3) = 8
Hint: | Evaluate 1 + 3.
1 + 3 = 4:
4 x + 4 = 8
Hint: | Isolate terms with x to the left hand side.
Subtract 4 from both sides:
4 x + (4 - 4) = 8 - 4
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
4 x = 8 - 4
Hint: | Evaluate 8 - 4.
8 - 4 = 4:
4 x = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 4 x = 4 by 4:
(4 x)/4 = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
x = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
