Answer:
71°
Step-by-step explanation:
Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary
since the sum of supplementary angles is equal to 180° :
180 - 109 = 71 is the measure of the co-interior angle
Let R be the region in the first quadrant bounded by the
graph of y = x² and the line y = 4.
(a) Find the area of the region R.
(b) A solid S has base R. Each cross-section of this solid
perpendicular to the y-axis is a semicircle, with its
diameter in R. Find the volume of the solid S.
(c) Another solid is formed by revolving R about the line
y = 7. Find the volume of this new solid.
a) The area within the region is [tex]\frac{16}{3}[/tex].
b) The volume of the solid [tex]S[/tex] is [tex]\pi[/tex] cubic units.
c) The volume of the solid of revolution is [tex]\frac{164}{3}\pi[/tex] cubic units.
How to apply integral formulas to determine areas and volumesa) The region is bounded between [tex](0,0)[/tex] and [tex](2, 4)[/tex], the area of the region is defined by the following integral formula:
[tex]A = \int\limits^{b}_{a} {[g(x)-f(x)]} \, dx[/tex] (1)
Where:
[tex]f(x)[/tex] - Lower function[tex]g(x)[/tex] - Upper function[tex]a[/tex] - Initial value[tex]b[/tex] - Final valueIf we know that [tex]f(x) = x^{2}[/tex], [tex]g(x) = 4[/tex], [tex]a = 0[/tex] and [tex]b = 2[/tex], then the area within the region is:
[tex]A = \int\limits^{2}_{0} {4-x^{2}} \, dx[/tex]
[tex]A = \frac{16}{3}[/tex]
The area within the region is [tex]\frac{16}{3}[/tex]. [tex]\blacksquare[/tex]
b) The volume of the solid [tex]S[/tex] is determined by the following integral formula:
[tex]V = \frac{\pi}{8} \int\limits^2_0 {x^{2}} \, dy = \frac{\pi}{8} \int\limits^2_0 {x^{2}\cdot (2\cdot x)} \, dx = \frac{\pi}{4}\int\limits^2_0 {x^{3}} \, dx[/tex]
[tex]V = \pi[/tex]
The volume of the solid [tex]S[/tex] is [tex]\pi[/tex] cubic units. [tex]\blacksquare[/tex]
c) The solid of revolution around an axis parallel to the [tex]x[/tex]-axis is described by the following formula:
[tex]V = \pi \int\limits^b_a {[[f(x)-k]^{2}-[g(x)-k]^{2}]} \, dx[/tex] (2)
Where [tex]k[/tex] is the y-coordinate of the axis of revolution.
If we know that [tex]f(x) = x^{2}[/tex], [tex]g(x) = 4[/tex], [tex]k = 7[/tex], [tex]a = 0[/tex] and [tex]b = 2[/tex], then the volume of the solid of revolution is:
[tex]V = \pi\int\limits^2_0 {[(x^{2}-7)^{2}-(4-7)^{2}]} \, dx[/tex]
[tex]V = \frac{164}{3}\pi[/tex]
The volume of the solid of revolution is [tex]\frac{164}{3}\pi[/tex] cubic units. [tex]\blacksquare[/tex]

The equation that could be used to find the length of the tomato patch is 0 = 3x² + 17x -160 option (A) is correct.
What is rectangle?It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
From the question:
The area of the vegetable garden = 170 square feet
The quadratic equation:
0 = 3x² + 17x -160
D = 2209
D > 0
The positive root of the quadratic equation is:
x = 5 ft (length of the tomato patch)
Thus, the equation that could be used to find the length of the tomato patch is 0 = 3x² + 17x -160 option (A) is correct.

Jade has $451. 89 in her checking account. After 3 checks, each for the same amount, are deducted from her account, she has $358. 92 left in her account. Assume she makes no other withdrawals or deposits. Which equations represent c, the amount of one check, in dollars? Select three options. 451. 89 minus c = 358. 92 451. 89 minus 3 c = 358. 92 358. 92 3 c = 451. 89 358. 92 c c c = 451. 89 c = 3 (451. 89 minus 358. 92).
The equation from the given equations, representing c, the amount of one check(for the given condition), in dollars is given by: Option C: [tex]358.92 + 3c = 451.89[/tex]
How to interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, [tex]a \div b[/tex] = a divided in b equal parts.
Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]
(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex])
For the given case, the amount those 3 checks together have is the difference in Jade's account's initial and final balance.
Amount deducted by 3 checks = $451.89 - $358.92
Amount of all 3 checks is $c
Thus, total of their amount = $(c + c + c) = 3c
Thus, we get:
[tex]3c = 451.89 - 358.92\\\\\text{Dividing both the sides by 3}\\\\c = \dfrac{451.89 - 358.92}{3} \text{\: (in dollars)}\\or\\\\358.92 + 3c = 451.89[/tex]
Thus, the equation from the given equations, representing c, the amount of one check(for the given condition), in dollars is given by: Option C: [tex]358.92 + 3c = 451.89[/tex]

A rectangle is 12cm longer than its wide. It's perimeter is 68m, how do you find it's length and width?
HELP!!
Answer:
Width: 1694 cm or 16.94 m
Length: 1706 cm or 17.06 m
Step-by-step explanation:
1. Write out the known equations:
First, the equation for the perimeter of a rectangle:
[tex]Perimeter = 2(Width) + 2(Length)[/tex]
We also know that the rectangle is 12 cm longer than it is wide. This leads to the second equation:
[tex]Length=Width+12[/tex]
2. Solve the system of equations for width:
Since we know the length in terms of width, and we know the perimeter, we can plug these values into the equation for the perimeter. First, let's rearrange the equation for perimeter to solve for width:
[tex]Perimeter = 2(Width) + 2(Length)\\Perimeter-2(Length)=2(Width)\\2(Width)=Perimeter-2(Length)\\Width=\frac{Perimeter-2(Length)}{2}[/tex]
Now, plug in the known values (since there are 100 cm in one metre, I'm multiplying the perimeter of 68 m by 100 to convert to centimetres--the perimeter of 68 m is equal to 6800 cm):
[tex]Width=\frac{6800-2(Width+12)}{2}[/tex]
Now, solve the equation for width:
[tex]Width=\frac{6800-2(Width+12)}{2}\\2(Width)=6800-2(Width+12)\\2(Width)=6800-2(Width)-24\\2(Width)+2(Width)=6800-24\\4(Width)=6800-24\\4(Width)=6776\\Width=1694cm[/tex]
3. Solve for length using width:
Now that we know the width, we can easily solve for the length using our previously established equation for length, [tex]Length=Width+12[/tex], as shown:
[tex]Length=Width+12\\Length=1694+12\\Length=1706cm[/tex]
4. Convert to metres.
If you want to know the answer in metres, you can convert from centimetres by dividing by 100:
1694/100 = 16.94 m
1706/100 = 17.06 m

The capacity of the square base can is 5 x 5 x 14 (bottom face area x height) = 350 (cm3).
The capacity of the circular base can is 3.5 x 3.5 x pi x 12 = 461.814120078.. (round to 462)
So, the circular base can has a greater capacity and by 462-350 = 112 cm3
The total of a number and -15 is at most -10?
Answer:
This sounds like you're trying to find the average of a group of numbers. For instance, suppose you want to find the average age of a group of people whose ages are 16, 18, 23, and 28. First, you sum the numbers: 16 + 18 + 23 + 28. You get 85. Then you divide 85 (the sum) by how many numbers you added together (4). So you divide 85 by 4, which gives you 21.25. Hope this helps!

Find the area of the square
The radius is 10
Since half of the diagonal of the square is 10, that means the whole diagonal is 20.
Area of the square = [tex]\frac{1}{2} *(20)^{2} =200[/tex]
Thus the area is 200. Hope that helps!
Solution:
Given:
Half of diagonal: 10 unitsTo find the diagonal, multiply half the diagonal by 2.
=> Diagonal = 2(Half of diagonal)=> Diagonal = 2(10) = 20 unitsWe also know that the sides of the square are equal. Let's use Pythagoras theorem to solve for the side length (c).
=> 20² = c² + c²=> 400 = 2c²=> 200 = c²=> c = √200 = 10√2Square the side length to obtain the area of the square.
=> (10√2)² = Area of square=> (10√2) x (10√2) = Area of square=> 100 x 2 = Area of square=> 200 units² = Area of squareThe area of the square is 200 units²

Answer:
6 dollars a week for every week she saved.
She already has 20 dollars so 10 weeks would be
20 + 10*6 = 10 weeks of saving
20+60=80
$80 would be saved up after 10 weeks.
