Find the area of the shaded region in the figure below, if the radius of the outer circle is 10 and the radius of the inner circle is 8. Keep your answer is terms of pi.
Answer:
I assume that the figure your figure is like this:
The Area of the shaded Region is 36π .
What is a Circle ?A circle is a round shaped figure whose all the point lie in the same plane.
It is given that Area of the shaded region needs to be found in the figure attached
Radius of the outer circle is 10
and Radius of the inner circle is 8
The area of the shaded region = Area of the outer circle - area of the inner circle
Area of a circle = πr²
r is the radius of the circle.
Area of the outer circle = π(10)²
Area of the outer circle = 100π
Area of the inner circle = π (8)²
Area of the inner circle = 64 π
Area of the shaded Region = 100π - 64 π
Area of the shaded Region = 36π
Therefore the Area of the shaded Region is 36π .
The missing figure is attached with the answer.

B. 2 + 0.15m = 3 + 0.25m
C.2m +0.25 = 3m +0.15
D.2 + 0.25m = 3 + 0.15m
Answer:
So i beiieve the answer is B
Step-by-step explanation:
Because if you thinl about the ride for A is $2 plus 25 cents so its 2 plus 25m thats per mile and b 3 dollars and 15 so u keep adding up until u get the same from both equations if u need further explanation let me know

Step-by-step explanation:
Please help me find the value of z.
====================================================
Work Shown:
Plug (x,y) = (3,2) into the F(x,y) function
[tex]F(x,y) = 2x^2 + 4y^2\\\\F(3,2) = 2(3)^2 + 4(2)^2\\\\F(3,2) = 34\\\\[/tex]
Next, find the gradient and plug in (x,y) = (3,2)
[tex]F(x,y) = 2x^2 + 4y^2\\\\\\\nabla F(x,y) = \Big< \frac{dF}{dx}, \frac{dF}{dy}\Big>\\\\\\\nabla F(x,y) = \Big< 4x, 8y \Big>\\\\\\\nabla F(3,2) = \Big< 4*3, 8*2 \Big>\\\\\\\nabla F(3,2) = \Big< 12, 16 \Big>\\\\\\[/tex]
This means,
[tex]z = \nabla F(3,2) \cdot \left(\vec{x} - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \left(\big< x,y \big> - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \big< x-3,y-2 \big> + F(3,2)\\\\\\z = \big< 12,16 \big> \cdot \big< x-3,y-2 \big> + 34\\\\\\z = 12(x-3)+16(y-2) + 34\\\\\\z = 12x-36+16y-32 + 34\\\\\\z = 12x+16y-34\\\\\\[/tex]
As a way to help check, note how plugging (x,y) = (3,2) into the last equation for z leads to z = 34. This helps confirm that we have the correct equation because the point (3,2,34) must be on F(x,y) and also on z since the plane is tangent to the F(x,y) curve at this point.

Which of the following is closer to 8
√61
√62
√65
√66
Answer:
√65
Step-by-step explanation:
We know that √64 is 8
So, the square root of the number closest to 64 in the list will be the closest to 8
In the List, √62 = √(64-2) [difference of 2]
√65 = √(64 + 1) [difference of 1]
Since √65 has the least difference from √64, we can say that √65 will be the closest to 8 in the given list

A city sets up 14 rows of chairs for an outdoor concert. Each row has 2 more chairs than the previous row. If the first row has 10 chairs, how many chairs are in the 8th row?
Answer:
24 chairs in the 8th row
Step-by-step explanation:
row 1 = 10 chairs
row 2 = 12 chairs
row 3 = 14 chairs
row 4 = 16 chairs
row 5 = 18 chairs
row 6 = 20 chairs
row 7 = 22 chairs
row 8 = 24 chairs
If A city sets up 14 rows of chairs for an outdoor concert. Each row has 2 more chairs than the previous row. If the first row has 10 chairs then 8th row has 24 chairs.
What is Sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The first row has 10 seats,
Each row has 2 more chairs than the previous row.
10,12,14.....
a=10,d=2,n=8
The nth term of Arithmetic sequence is aₙ=a+(n-1)d
an equal to a plus n minus one times of d
a₈=10+(8-1)2
=10+7(2)
=10+14
=24
Hence If the first row has 10 chairs, then the 8th row has 24 chairs.

The population of Laredo, Texas, was about 215,500 in 2007. It was about 123,000 in 1990. If we assume that the population growth is constant and t represents the number of years after 1990, write a linear equation
Answer:
y=5441t+123,000
Step-by-step explanation:
5441 is the population increase per year and 123,000 is when we start added the population increase. to get this equation i found the population increase between 2007 and 1990 which is 215,500-123,000 which is 92,500. to find the population increase per year you divide that by 17 which is the difference between 2007 and 1990 and you would get 5441.176. but since you can have part of a person i rounded it to 5441.
Answer: y=5441t+123000
We know the population was 215500 in 2007
We also know the population was about 123000 in 1990
So first we want to find the slope (m=y2-y1/x2-x1), we subtract those two numbers 215500-123000 and subtract 2007-19990. Leaving us with 92500/17, once you divide that you’ll get 5441.17647 . But since we are talking about people you round to the nearest whole number leaving us with 5441.

Questions – Impulse and Momentum
A 6.00 N force acts for 5.00 seconds on a 1.50 kg mass. Find:
A) The impulse which acted upon the mass.
B) What change in momentum is produced?
The value of the impulse will be 30 Newton-second. And the value of the momentum will be 30 kg-m/s.
What are impulse and momentum?A strong and ignorant passion or drive to act is known as an impulse.
A traveling body's momentum is measured as the combination of its mass and velocity.
A 6.00 N force acts for 5.00 seconds on a 1.50 kg mass.
Then the impulse is given as
Impulse = Force x Time
Impulse = 6 x 5
Impulse = 30 N-sec
Then the value of the momentum will be
P = m x dv
We know
F = ma
6 = 1.5a
a = 4 m/s²
Then the velocity will be
dv = a x t
dv = 4 x 5
dv = 20 m/s
Then the momentum will be
P = 1.5 x 20
P = 30 kg-m/s

The baby gains 3.25lbs in the last 4 months.
This problem can be solved by simple subtraction. Take the total amount and subtract the 4 month increments in order to find the find 4 months.
Total = 1st 4 months + 2nd 4 months + 3rd 4 months
11 = 4.25 + 3.5 + 3rd 4 months
