Find the line integral along the curve C from the origin along the x-axis to the point (6, 0) and then counterclockwise around the circumference of the circle x2 y2
Parameterize C by the two vector functions,
r(t) = (1 - t) (0, 0) + t (6, 0) = (6t, 0)
with 0 ≤ t ≤ 1, and
s(t) = (6 cos(t), 6 sin(t))
with 0 ≤ t ≤ π/2.
Then the line integral over C is equal to the sum of the line integrals over each path:
[tex]\displaystyle \int_C dS = \int_0^1 \|r'(t)\| \, dt + \int_0^{\frac{\pi}2} \|s'(t)\| \, dt[/tex]
[tex]\displaystyle \int_C dS = \int_0^1 \sqrt{6^2 + 0^2} \, dt + \int_0^{\frac{\pi}2} \sqrt{(-6\sin(t))^2 + (6\cos(t))^2} \, dt[/tex]
[tex]\displaystyle \int_C dS = 6 \int_0^1 dt + 6 \int_0^{\frac{\pi}2} dt[/tex]
[tex]\displaystyle \int_C dS = 6 + \frac{6\pi}2 = \boxed{6+3\pi}[/tex]
What is the volume, in cubic inches, of a rectangular prism with a height of 7 inches, a width of 10 inches, and a length of 9 inches?
Answer:
Step-by-step explanation:
87
Answer:
630 in.³
Step-by-step explanation:
To find the volume of a rectangular prism, you can multiply the height, times the width, times the length. So, let's go ahead and do that with the values of the given prism.
7 × 10 × 9 = 70 × 9 = 630
So, our volume is 630...but not so fast. We also have to put in our units. Our units are inches × inches × inches, or inches³. So our final value is 630 in.³

Prices are going up in the ratio 6:5 Write a 60% decrease as a ratio.
HELP PLSSSSSSSSSSSSSSSSSSSSS
Answer:
To Decrease an amount in a given Ratio, we need to multiply by a fraction that is less than one. For example, in scaling down a recipe for four people into a recipe for 3 people, we would use the ratio of 3 : 4 which means we would multiply all our recipe amounts.

7. Find the length of AB
please answer will mark brainelist :)
Answer:
A) 17 m B) 20.8 m
Step-by-step explanation:
I cannot mark on the image but you can find the length of A to the bottom of the shape by subtracting 26-11
26-11 = 15
I will label the triangle as ABC (AB the length we trying to find, BC is 15 *it is angle B to the intercept of A and the bottom of the shape, AC is 8 because it is parallel to the given length 8)
AB is the hypotenuse
We can use the pythagorean theorem to find length AB (a^2 + b^2 = c^2)
a and b is the legs which is 8 and 15
8^2 + 15^2 = AB^2
64 + 225 = AB^2
289 = AB^2
√289 = AB (to undo a square, you use square roots)
√289 = 17
AB = 17 m
Now we need to find the hypotenuse of AC
the same thing, we did for problem A, use the pythagorean theorem
17^2 + 12^2 = AC^2
289 + 144 = AC^2
433 = AC^2
√433 = AC
√433 is about 20.808...
round to the tenth as stated in the directions
AC = 20.8 m

A business valued at $96 000 is purchased for a down payment of 25% and payments of $4000 at the end of every three months. If interest is 9% compounded monthly,
what is the size of the final payment?
Write your answer as 2,569.43.
Size of final payment is $6392.43
Given that formula for compound interest is P(1+r/n[tex])^{nt}[/tex]
where P is initial principal
r is interest rate
n is compound times per period
t is time in years
We find all the variables in the formula in order to get our answer.
Initial principal = 96000 less 25%= 72000
interest rate = 9%
number of compound times= 12
time in years =4.25 years (whole period is 4.5 years since number of payments to complete balance will take 54 months)
Hence principal and CI after 4 years and 3 months(the second to last payment)
72000(1+0.09/12)^12x4.25=$105,393.6
We use $105,393.6 as our principal to calculate the whole interest and principal for the period in order to find last payment
105393.6(1+0.09/12)^12x0.25=$107,786.03
interest for the final month = $107786.03-$105,393.6=$2392.43
To get our final payment, we add the principal payment of $4000 to final compounded interest =$6392.43

What is an arithmetic progression?
Every term following the first is derived by adding a constant value, known as the common difference, in an arithmetic progression.
We have,
4 + 7 + 10 + 13 + 16 + 19 + 22 + 25 + 28 +31 + 34 + 37 + 40
Arithmetic progression formula:
[tex]a_{n}=a_{1}+(n-1)d[/tex]
where
[tex]a_{n}[/tex] = the nᵗʰ term in the sequence
[tex]a_{1}[/tex] = the first term in the sequence
[tex]d[/tex] = the common difference between terms
By using arithmetic progression formula we can find last term of an Arithmetic series.
[tex]a_{n}=a_{1}+(n-1)d[/tex]
[tex]a_{n}[/tex]= 4 + (n-1)3
[tex]a_{n}[/tex] = 4 + (13-1)3
[tex]a_{n}[/tex] = 40.
we have calculated the last term by using arithmetic progression formula which is 40.
Hence, This expression 40=4+(n-1)3 represents the correct arithmetic progression.

write the standard form of the equation of the circle with the given characteristics end point of diameter (-4,-1) , (4,1)
Answer:
x² + y² = 17
Step-by-step explanation:
The standard equation of a circle is :
(x -h)² + ( y -k) ²= r², where (h, k) are the a coordinate of the center of the circle and r is the radius of the circle
If the end point of diameter has the coordinates (-4,-1) and (4,1) then the center is at the origin so we have (h= 0, k= 0)
The radius is half of the diameter so is the distance form (0,0) to (4, 1).
We can use Pythagorean Theorem to find r²
r ² = 4²+1² = 17
(x -h)² + ( y -k) ²= r², substitute what we found out
(x -0)² + ( y -0) ²= 17
x² + y² = 17
This is the equation of the circle given characteristics end point of diameter (-4,-1) , (4,1)

a.
Employee #1.
b.
Employee #2
c.
Employee #3
d.
They each had the same dollar amount in sales.
The employee who did not have the same dollar amount in sales for the month of February as the other two employees is (a) Employee 1.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Earnings of three employees in the month of February are :
Employee 1 = 4.7 = $4700
Employee 2 = 4.9 = $4900
Employee 3 = 4.4 = $4400
Earnings of employee 1 = $2,000 + 3% on all sales
Let the amount of all sales be x.
2000 + (3% x ) = 4700
2000 + 0.03x = 4700
0.03x = 2700
x = 90,000
Earnings of employee 2 = 7% on all sales
Let the amount of all sales be x.
0.07x = 4900
x = $70,000
Earnings of employee 3 = 5% on the first $40,000 + 8% on anything over $40,000
Let the amount of sales be 40,000 + x.
(0.05 × 40,000) + (0.08 x) = 4400
2000 + 0.08x = 4400
0.08x = 2400
x = $30,000
Amount of sales = $40,000 + $30,000 = $70,000
Hence employee 1 did not have the same amount as the other 2 in February.

Find the equation of the line with slope m = 2 that contains the point (8,19).
Answer:
y = 2x + 1
Step-by-step explanation:
Pls mark as brainliest
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line with slope m = 2 and point (8, 19) is
y = 2x + 3
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope:
m = 2
Point = (8, 19) = (x, y) _____(A)
Now,
The equation of a line is given as,
y = mx + c ______(B)
Substitute (A) into (B)
From (A) we get,
19 = 2 x 8 + c
19 = 16 + c
c = 19 - 16
c = 3
Now,
The equation of the line with slope m = 2 and point (8, 19) is
y = 2x + 3
Thus,
The equation of the line with slope m = 2 and point (8, 19) is
y = 2x + 3
