IntegralsArea of a Region Formula: [tex]\displaystyle A = \int\limits^b_a {[f(x) - g(x)]} \, dx[/tex]
Step-by-step explanation:
We know that by definition, an integral is an antiderivative.
Also by definition, an integral is also the area under the curve. This can be extended to area between 2 curves.
We have a formula specifically to find an area under a curve (region), as listed above.
∴ our answer is D.

On opening night of the play "The Music Man" at the Lewiston Civic Theater, 946 tickets were sold. The total receipts for the performance was $10,588. Children tickets cost $10 apiece, adult tickets cost $14 aplece, and senior citizen tickets
cost $6 apiece. If the combined number of children and adult tickets exceeded twice the number of senior citizen tickets by 334, determine how many tickets of each typo were sold.
There were children tickets, adult tickets, and senior citizen tickets sold.
Answer:
The number of tickets sold are
Children = 256
Adults = 486
senior citizen = 204
Step-by-step explanation:
let
x = children ticket = $10 per piece
y = adult ticket = $14 per piece
z = senior citizen = $6 per piece
x + y + z = 946 ( total tickets sold ) ---------- ( 1 )
Total receipt for performance
10x + 14y + 6z = $10588 --------------- ( 2 )
since the combined number of children and Adult tickets exceeded twice the number of senior citizen tickets by 334
x + y - 2z = 334 --------- ( 3 )
substract equation 3 from equation 1
3z = ( 946 - 334 ) = 612 therefore Z = 204
next we multiply equation (1) by 14
14x + 14y + 14z = 13244 ---------- ( 4 )
substract equation (2) from ( 4 )
4x + 8z = 2656
= 4x + 8(204) = 2656
= 4x = 2656 - 1632
therefore : x = 256
back to equation 1
256 + y + 204 = 946
y = 946 - ( 256 + 204 ) = 486
Hence the number of tickets sold are
Children = 256
Adults = 486
senior citizen = 204

During photosynthesis, plants take in carbon dioxide causing its concentration in the atmosphere to ___________.
a) increase
b) decrease
If more airplanes and cars are used (both of which burn fossil fuels), carbon levels will increase.
Group of answer choices
True
False
Answer:
A
False
Step-by-step explanation:
Answer:
1) increase
explanation: In most plants, the uptake of CO2 through photosynthesis is reduced by a side reaction called photorespiration. The research group has now found that the CO2 increase in the atmosphere over the 20th century has shifted the balance between photosynthesis and photorespiration toward photosynthesis.
2) think its false

Which expression is equivalent to (4 + 6i)2? –20 + 48i 8 + 12i 16 – 36i 20 + 48i
========================================
Work Shown:
x = (4+6i)^2
x = (4+6i)(4+6i)
x = y(4+6i) ...... let y = 4+6i
x = 4(y)+6i(y) ..... distribute
x = 4(4+6i)+6i(4+6i) .... plug in y = 4+6i
x = 16+24i+24i+36i^2 ..... distribute again
x = 16+24i+24i+36(-1) .... use the fact that i^2 = -1
x = 16+24i+24i-36
x = 16-36+24i+24i
x = -20+48i
Answer:
A -20+28i

Answer:
[tex] x = \sqrt{189} [/tex]
Step-by-step explanation:
Use pythagorean theorem to solve for x.
Thus:
[tex] a^2 + b^2 = c^2 [/tex]
Where,
a = 6
b = x = ?
c = 15
Plug in the values into the equation
[tex] 6^2 + x^2 = 15^2 [/tex]
[tex] 36 + x^2 = 225 [/tex]
Subtract 36 from each side
[tex] x^2 = 225 - 36 [/tex]
[tex] x^2 = 189 [/tex]
Take the square root of both sides
[tex] x = \sqrt{189} [/tex]

Answer:
11/30 or 0.36
Step-by-step explanation:
Answer:
11/30
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(1/5, 1/6) = 30
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(1/5×6/6)+(1/6×5/5)=?
Complete the multiplication and the equation becomes
630+530=?
The two fractions now have like denominators so you can add the numerators.
6+5/30=11/30
The fraction cannot be simplified, final answer 11/30

ane Windsor financed a $5,900 ski boat with a 12% add-on interest installment loan for 12 months. Given the loan required a 10% down payment, determine the following:
The amount of the finance charge?
The amount of the finance charge rebate if the loan were to be paid after the 10th payment?
Answer:
Jane must pay $ 5,947.2 over 12 months. Of that amount, $ 637.2 will correspond to interest generated by the loan, which will be paid in 12 installments of $ 495.6.
Step-by-step explanation:
Jane Windsor acquired a ski boat for $ 5,900, paying a down payment of 10% and financing the remainder of the price at an annual interest rate of 12%.
Thus, since 5,900 x 0.1 is equal to 590, the financed amount arises from the subtraction between 5,900 minus 590, which yields a financed amount of $ 5,310.
Therefore, the amount to be paid monthly arises from the following calculation:
5,310 x 1.12 = Amount with interest
5,947.2 = Amount with interest
5,947.2 - 5,310 = Interest
637.2 = Interest
5,947.2 / 12 = Monthly payments
495.6 = Monthly payments
Therefore, Jane must pay $ 5,947.2 over 12 months. Of that amount, $ 637.2 will correspond to interest generated by the loan, which will be paid in 12 installments of $ 495.6.
The length of a rectangle is four times its width.
If the perimeter of the rectangle is 50 cm, find its area.
Answer:
width=25/3
Length=75/3
Step-by-step explanation:
Given
Perimeter=50
Let width=x
Length=4x
So perimeter =2(length+width)
2(length+width)=50
2(X+2x)=50
3x=25
X=25/3
So width=25/3
Length=75/3
