Oil is leaking from an oil tanker, and an expanding circle of oil is spreading on the ocean. The radius, r, of the circle measured in inches is modeled by the function r(s)=3 sqrt s, where s is time in seconds. The area of the spill when s=5 seconds is ___ pi square inches.
Answer:
[tex]Area=45\pi$ square inches[/tex]
Step-by-step explanation:
The radius, r of the expanding circle of oil is modeled by the function:
[tex]r(s)=3\sqrt{s}[/tex], where s is time in seconds.
When s=5
Radius, [tex]r(5)=3\sqrt{5}$ inches[/tex]Area of a circle[tex]=\pi r^2[/tex]
Therefore, area of the oil spill when s=5 seconds is:
[tex]Area=\pi (3\sqrt{5})^2\\=\pi *3^2*(\sqrt{5})^2\\=\pi *9*5\\$Area=45\pi$ square inches[/tex]
The area of the spill when s=5 seconds is 45pi square inches.

Answer:
Part A would be B, and Part B would be C
Step-by-step explanation:
With the graph that B shows, the distance to time ratio is cut very sharply, indicating that there wasn't a constant speed throughout the entire time, up until where the graph went from shooting upwards to slightly inclining.
With the graph that C shows, out of all of the graphs, it is the only graph that shows the fact that the person went back to their starting point, indicating that they did return home because they forgot something.

Anthony has a combination of 104 nickels and quarters totaling $22. Which system of linear equations can be used to find the number of nickels?
Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21

Step-by-step explanation:
h(x) = x2 – 3
If the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g.
Find the expression for g(x).
Answer:
[tex]g(x)=x^2+1[/tex]
Step-by-step explanation:
The given function is
[tex]h(x)=x^2-3[/tex]
If a function translated vertically upward by p units, then we need to add p in the function value to get the new function.
It is given that if the graph of h is translated vertically upward by 4 units, it becomes the graph of a function g. So,
[tex]g(x)=h(x)+4[/tex]
[tex]g(x)=x^2-3+4[/tex]
On simplification, we get
[tex]g(x)=x^2+1[/tex]
Therefore, the required function is [tex]g(x)=x^2+1[/tex].
David correctly factored the expression m^2-12m - 64.
Which expression did he write?
(1) (m - 8)(m - 8) (3) (m - 16)(m +4)
(2) (m - 8)(m + 8) (4) (m +16)(m - 4)
Explain why
Answer:
(m-16)(m+4)
Step-by-step explanation:
To factor a quadratic expression
First write the variable in each parentheses, then put negative/ positive, after that ask yourself what numbers have the product of the coefficient of x^0 and the sum of x^1.
David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4).
How to factor an equation?An equation can be factored into its factors by splitting the middle term of the equation.
The given expression can be factored as shown below:m^2 - 12m - 64 = 0
⇒ m^2 - 16m +4m - 64 = 0
⇒ m(m - 16) + 4(m - 16) = 0
⇒ (m + 4)(m - 16) = 0
The factors of the equation m^2 - 12m - 64 = 0 are (m - 16)(m + 4).
Therefore, we have found that David correctly factored the expression m^2 - 12m - 64 and got (m - 16)(m + 4). The correct answer is option C or (3).

The value of an antique can be predicted by the expression 250 * (1.12) ^ t where is the number of years since 2014. What does the value 250 represent?
Answer:
mark brainlyest and I will
The value 250 represents the predicted value of antique in year 2014.
Given Expression,
[tex]250\times(1.12)^{t}[/tex]
Here [tex]t[/tex] represents the no. of years since 2014.
Now clearly 250 shows here the predicted price of the antique in year 2014 and [tex](1.12)^t[/tex] shows how much percent the product is increasing over the year.
Hence the value 250 represents the predicted value of antique in year 2014.

Variable b is 7 more than variable c. Variable b is also 1 less than variable c. Which pair of equations best models the relationship between b and c? (1 point)
a
b = c + 7
b = c − 1
b
b = c − 7
b = c + 1
c
c = b + 7
c = b − 1
d
c = b − 7
c = b − 1
Answer:
First one
Step-by-step explanation:
Variable b is 7 more than variable c:
b = c + 7
Variable b is also 1 less than variable c:
b = c - 1
Answer:
B:
b = c + 7
b = c - 1
Step-by-step explanation:
"Variable b is 7 more than variable c" can be expressed mathematically as
b = c + 7
"Variable b is 1 less than variable c" can be expressed mathematically as
b = c - 1
So the second pair,
b = c + 7
b = c - 1
best models the relationship between b and c

Find the value of x. Will mark brainliest.
Answer:
3.625
Step-by-step explanation:
Line segment IK = 35.
This is a parallelogram, in which:
LJ is a line bisector of IK; line Imidpoint = line segment kmidpoint.
IK = (4x + 3) + (4x + 3)
35 = (4x + 3) + (4x + 3)
Simplify. Combine like terms:
35 = 8x + 6
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents & Roots
Multiplication
Division
Addition
Subtraction.
First, subtract 6 from both sides:
35 (-6) = 8x + 6 (-6)
35 - 6 = 8x
29 = 8x
Divide 8 from both sides:
(29)/8 = (8x)/8
x = 29/8
x = 3.625
3.625 is your answer.

Answer:
X= 8
The reason why X equals 8 is because the gave you the measurement of points I and K. They have created an expression to find points I and K and all they ask you to do is find the value of x.
To find the value of x, think about the measurement of points I and K. The measurements of point I and K equals 35. So we have to substitute a number for x that would make the expression equal 35. This is how I did it, so I thought 4 times what would get me close to 35. Then 4*8 came to my head and that automatically equals 32 and then when you add the three you get 35!
