Answer:
Possible expressions for the radius of the can and the depth of the paint in the can are [tex]r = \sqrt{9\cdot x^{2}+24\cdot x+16}[/tex] and [tex]h = 2\cdot x[/tex], respectively.
Step-by-step explanation:
Let be the initial volumes of the initial cans represented by these expressions:
[tex]V_{1} = (8\cdot x^{3}+31\cdot x^{2}+32\cdot x)\cdot \pi[/tex] (1)
[tex]V_{2} = (10\cdot x^{3}+17\cdot x^{2})\cdot \pi[/tex] (2)
The resulting volume of the paint can is the sum of the two functions:
[tex]V_{3} = (18\cdot x^{3}+48\cdot x^{2}+32\cdot x)\cdot \pi[/tex] (3)
Then, we proceed to factor the polynomial:
[tex]V_{3} = 2\cdot (9\cdot x^{2}+24\cdot x +16)\cdot x \cdot \pi[/tex]
[tex]V_{3} = \pi\cdot (9\cdot x^{2}+24\cdot x + 16)\cdot (2\cdot x)[/tex] (3b)
By direct comparison with the volume formula for the cylinder we have the following expressions:
[tex]r^{2} = 9\cdot x^{2}+24\cdot x + 16[/tex]
[tex]r = \sqrt{9\cdot x^{2}+24\cdot x+16}[/tex]
[tex]h = 2\cdot x[/tex]
Possible expressions for the radius of the can and the depth of the paint in the can are [tex]r = \sqrt{9\cdot x^{2}+24\cdot x+16}[/tex] and [tex]h = 2\cdot x[/tex], respectively.

plz help 30 points will give brainliest
Answer:
Question A)
[tex]=\sqrt{6}x[/tex]
Question B)
[tex]=3a\sqrt{a}[/tex]
Question C)
[tex]=5\sqrt{2}b^2[/tex]
Step-by-step explanation:
A)
We are given:
[tex]\sqrt{6x^2}\, \text{ where } x\geq 0[/tex]
We can rewrite the expression:
[tex]=\sqrt{6}\cdot \sqrt{x^2}[/tex]
The square root and square will cancel each other out. Thus:
[tex]=\sqrt{6}x[/tex]
B)
We are given:
[tex]\sqrt{9a^3}[/tex]
Rewrite:
[tex]=\sqrt{9}\cdot \sqrt{a^3}[/tex]
Note that the square root of 9 is simply 3. We can also factor the second part:
[tex]=3\cdot \sqrt{a^2\cdot a}[/tex]
Rewriting:
[tex]=3\cdot\sqrt{a^2}\cdot\sqrt{a}[/tex]
Simplify:
[tex]=3a\sqrt{a}[/tex]
C)
We are given:
[tex]\sqrt{50b^4}[/tex]
Rewrite. Note that 50 = 25(2):
[tex]=\sqrt{25}\cdot \sqrt{2}\cdot \sqrt{b^4}[/tex]
Simplify. We can rewrite the factor as:
[tex]=5\cdot \sqrt{2}\cdot \sqrt{(b^2)^2}[/tex]
The square and square root will cancel out. Thus:
[tex]=5\sqrt{2}b^2[/tex]

jesse has never used the sliding board at his daycare because he is afraid. His teacher has encouraged him, but he refuses to slide down. one day his mother stands at the bottom And say's Jesse let's go and slides into his mother's arms Laughing The situation is a example of Social referencing. Option (d) is correct.
What do you mean by Situation?Situation refers to a group of conditions or a current state of events.
Social reference is the method through which newborns control their behavior toward surrounding items, people, and circumstances by observing the emotive displays of an adult.
For adaptive social functioning to occur, one must recognize and make use of the emotional communication of others. The ability to negotiate complicated and frequently ambiguous settings is known as social referencing in the developmental literature and social appraisal in adult studies.
Therefore, Option (d) is correct. The situation is a example of Social referencing.

find the mean median mode, round to the neaerest tenth. 60,70,75,78,80,80,83,85,87,90.90,90,90,93,95,95,98,100.
Answer:
Mean: 84.6
median:85
mode:90,80
range:40
minimum:60
maximum:100
Step-by-step explanation:
Answer:
mean = 85.5
median = 88.5
mode = 90
Step-by-step explanation:
Okay, so the mean is the sum of the terms divided by the total number of term so basically:
60 + 70 + 75 + 78 + 80 + 80 + 83 + 85 + 87 + 90 + 90 + 90 + 90 + 93 + 95 + 95 + 98 + 100 = 1,539
1,539 ÷ 17 = 85.5
Now, the median is just the number in the middle so we already have our numbers in order so the middle numbers are 87 and 90, so we just have to add them together and then divide by 2:
87 + 90 ÷ 2 = 88.5
and the mode is just the number that's repeated most, and that number is 90

According to the Chronicles of Contrived Statistics (March, 2016), the probability that Elon Musk will offer you a free trip into space in the next month is 41%. The probability that scientists from Area 51 will start selling pet aliens next month is 27%. Finally, the probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 24%. What is the probability that both Elon Musk will offer you a free trip into space and scientists from Area 51 will start selling pet aliens in the next month?
Answer:
[tex]P(A\ and\ B) = 44\%[/tex]
Step-by-step explanation:
Given
Represents the event as follows:
A = [tex]Elon\ Musk[/tex] will offer you a [tex]free\ trip[/tex] into space in the next month\
B = Scientists from [tex]Area\ 51[/tex] will [tex]start\ selling[/tex] pet aliens next month
So, we have:
[tex]P(A) = 41\%[/tex]
[tex]P(B) = 27\%[/tex]
[tex]P(A\ or\ B) = 24\%[/tex]
Required
Determine [tex]P(A\ and\ B)[/tex]
This is calculated as:
[tex]P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)[/tex]
So, we have:
[tex]P(A\ and\ B) = 41\% + 27\% - 24\%[/tex]
[tex]P(A\ and\ B) = 44\%[/tex]
If function g is a quadratic function that contains the points (-3,5) and (0,14), which statement is true over the interval [-3,0]?
Your answer for this question is B
The average rate of change of f(x) is less than average rate of change of g(x). Then the correct option is C.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function f(x) is given in the table, then the rate of change of the function f(x) will be
Rate of change of f(x) = (-2 + 4.5) / (-2 + 3)
Rate of change of f(x) = 2.5
If function g is a quadratic function that contains the points (-3,5) and (0,14).
Then the rate of change of the function g(x) will be
Rate of change of g(x) = (14 - 5) / (0 + 3)
Rate of change of g(x) = 9/3
Rate of change of g(x) = 3
Thus, the average rate of change of f(x) is less than average rate of change of g(x).
Then the correct option is C.

You are making a fence for your garden. The length is five less than two times
the width
a. Write a polynomial that represents the perimeter of the garden.
b. Write a polynomial that represents the area of the garden
c. Find the perimeter and area of the garden when the width is 8 feet.
Answer:Answer: (a) = P = 2(x + 2x-5) = 2(3x-5) = 6x - 10.
Step-by-step explanation:
Part a : Polynomial represents the perimeter of the garden is 6W-10
Part b : Polynomial represents the area of the garden is [tex]2w^{2}-5w[/tex]
Part c : Perimeter = 38 feet and area = 88 feet square
What is polynomial?A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables
What is perimeter?A perimeter is a closed path that encompasses, surrounds
What is area?Area is the quantity that expresses the extent of a region on the plane or on a curved surface
Given,
Length is five less than two times the width
Consider
L is the length and W is the width
Then,
L=2W-5
Part a
Perimeter = 2(L+W)
Substitute the value of L
P=2(L+W)
P=2((2W-5)+W)
P=2(2W-5+W)
P=2(3W-5)
Perimeter= 6W-10
Part b
Area of the garden = L×W
Area = (2W-5)W
Area = [tex]2w^{2}-5w[/tex]
Part c
Given width W = 8 feet
Perimeter = 6W-10
P=6×8-10
Perimeter =38 feet
Area = [tex]2w^{2}-5w[/tex]
Area=[tex]2(8^{2})-5(8)[/tex]
Area = 88 feet square
Hence,
Part a : Polynomial represents the perimeter of the garden is 6W-10
Part b : Polynomial represents the area of the garden is [tex]2w^{2}-5w[/tex]
Part c : Perimeter = 38 feet and area = 88 feet square
