Step-by-step explanation:
Simplifying
x + -5y = 3v
Solving
x + -5y = 3v
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
x + -5y + 5y = 3v + 5y
Combine like terms: -5y + 5y = 0
x + 0 = 3v + 5y
x = 3v + 5y
Simplifying
x = 3v + 5y

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?
Answer:
118°
Step-by-step explanation:
When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.
Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.
Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.
(5x + 17) + (15x - 17) = 180
5x + 15x + 17 - 17 = 180
20x = 180
20x/20 = 180/20
x = 9°
Nkw let's substitute x = 9 into the equations
5x + 17 =
5(9) + 17 =
= 62°
15x - 17 =
15(9) - 17 =
= 118°
Both equations should add up to be 180°.
Therefore the measure of the largest angle is 118°.
(-3x^2)*(2x^2-3x^3y+5x^3y)
Answer:
-36x+134xy
Step-by-step explanation:
-3x to the power of 2 is -9x
2x to the power of 2 is 4x
now you have -9x times 4x-3x^3y+5x^3y
3x to the power of 3y is 9xy
5x to the power of 3y is 125xy
now you have: -9x times 4x-9xy+125xy
which is: -36x+9xy+125xy
which is: -36x+134xy

63 is what percent of 66?
Answer:
63 is 95.45% of 66
Step-by-step explanation:
In order to determine the percentage of 63 relative to 66, we could simply divide 63 by 66 (which represents 63 as a percentage of a whole, 66):
[tex]\frac{63}{66}[/tex] = (63 ÷ 66) × 100 = 0.9545 × 100 = 95.45%
Therefore, 63 is 95.45% of 66.

Select the correct answer. What are the roots of the quadratic equation Y =x^2-10x+125 A x=5+-5√6 B x=-5+-10i C x=-5+-5√6 D x=5+-10i
Answer:
Option D: x = 5 ± 10i
Step-by-step explanation:
Given the quadratic equation, y = x² - 10x + 125,
where:
a = 1, b = -10, and c = 125:
Use the following quadratic formula to solve for the roots:
[tex]\displaystyle\mathsf{x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}}[/tex]
[tex]\displaystyle\mathsf{x=\frac{10\pm\sqrt{(-10)^2-4(1)(125)}}{2(1)}}[/tex]
[tex]\displaystyle\mathsf{x=\frac{10\pm\sqrt{100-500}}{2}\:=\:\frac{10\pm\sqrt{-400}}{2}}[/tex]
Apply the imaginary unit rule, where it states that: [tex]\displaystyle\mathsf{\sqrt{-a}\:=\:i\sqrt{a}}[/tex] :
[tex]\displaystyle\mathsf{x=\frac{10\pm\:20i}{2}}[/tex]
[tex]\displaystyle\mathsf{x=\frac{10\:+\:20i}{2}\:=\frac{10(1\:+\:2i)}{2}\:=\:5(1+2i)}\:=5+10i}[/tex]
[tex]\displaystyle\mathsf{x=\frac{10\:-\:20i}{2}\:=\frac{10(1\:-\:2i)}{2}\:=\:5(1-2i)}\:=5-10i}[/tex]
Therefore, the correct answer is Option D: x = 5 ± 10i .

0.1z = 0.2(z + 2)
z=?????????????????
Answer:
-4
Step-by-step explanation:
0.1z = 0.2(z + 2)
0.1z = 0.2z + 0.4
-0.1z = 0.4
z = -4
Answer:
z = -4
Step-by-step explanation:
Distributive Property: a(b + c) = ab + ac
1. Distribute
0.1z = 0.2(z) + 0.2(2)
0.1z = 0.2z + 0.4
2. Subtract 0.2z from both sides
0.1z - 0.2z = 0.2z - 0.2z + 0.4
-0.1z = 0.4
3. Divide both sides by -0.1 to isolate the variable
-0.1z ÷ -0.1 = 0.4 ÷ -0.1
z = -4

Step-by-step explanation:
Using polar coordinates, evaluate the integral which gives the area which lies in the first quadrant between the circles x2 y2=64 and x2−8x y2=0.
You mention circles, so I assume the missing symbols are plus signs.
The first circle has equation x² + y² = 64 = 8², so it's centered at the origin and has radius 8. In polar coordinates, we take x = r cos(θ) and y = r sin(θ). Then this circle's equation is
(r cos(θ))² + (r sin(θ))² = 64
r² (cos²(θ) + sin²(θ)) = 8²
r = 8
Complete the square in the second circle's equation to determine its center and radius:
x² - 8x + y² = x² - 8x + 16 + y² = 16 ⇒ (x - 4)² + y² = 4²
so the second circle is centered at (4, 0) with radius 4. In polar coordinates, this equation becomes
(r cos(θ) - 4)² + (r sin(θ))² = 16
r² (cos²(θ) + sin²(θ)) - 8r cos(θ) + 16 = 16
r² - 8r cos(θ) = 0
r - 8 cos(θ) = 0
r = 8 cos(θ)
Determine where these two circles intersect:
8 = 8 cos(θ)
cos(θ) = 1
θ = arccos(1) + 2nπ
θ = 2nπ
where n is any integer. So both circles intersect once at (8, 0), which means they are tangent to one another, and since the second circle's radius is smaller, it must lie completely within the larger one.
The region between the two circles is the set
R = {(r, θ) : 0 ≤ θ ≤ π/2 and 8 cos(θ) ≤ r ≤ 8}
The area of R is given by the double integral,
[tex]\displaystyle \iint_R dA = \int_0^{\frac\pi2} \int_{8\cos(\theta)}^8 r \, dr \, d\theta[/tex]
or the single integral
[tex]\displaystyle \iint_R dA = \frac12 \int_0^{\frac\pi2} \left(64 - 64\cos^2(\theta)\right) \, d\theta[/tex]
Recall the half-angle identity for cosine:
cos²(x/2) = (1 + cos(x))/2
Then the area is
[tex]\displaystyle \iint_R dA = 16 \int_0^{\frac\pi2} \left(1 - \cos(2\theta)\right) \, d\theta[/tex]
[tex]\displaystyle \iint_R dA = 16 \left(\theta - \frac12 \sin(2\theta)\right) \bigg|_0^{\frac\pi2}[/tex]
[tex]\displaystyle \iint_R dA = \boxed{8\pi}[/tex]

A worker at a cabinet shop is cutting out pieces of wood for a dresser. He needs pieces that are 4 1/4inches long. Each saw cut wastes 1/8 inch of wood. The board he has is 7 feet long. How many pieces can he make from this board?
Answer: he will be able to make 19 full pieces
Step-by-step explanation:
1. Start off by making 7 feet into 84 inches so the measurements can match.
2. Add 4/14 inches and the 1/8 a inch together so you know how much is being taken off 84 inches. The amount will be 35/8 inches.
3. Divide 84 inches by 35/8 inches = 19 1/5
4. The whole number of the answer will be how many boards you can make from the board.
Some school students are raising money for a charity. Their goal is to raise $1000. They already have $232 from bake sales. To raise the remainder, they are planning a walk-a-thon. If each person walking raises $24, how many walkers will the students need to reach their goal?
Answer:
It will be needed 32 walking students to reach the goal
Step-by-step explanation:
1000 - 232
768/24= 32
Answer:
32 walkers.
Step-by-step explanation:
$1000 minus the $232 we have already raised from the bake sale to determine the amount we need to raise from the walk-a-thon.
1000 - 232 = 768.
So in order to raise 768, and we are raising $24 per person we will divide to figure out how many people we need.
768 / 24 = 32.
You can check this answer by multiplying 24 and 32, and then adding the 232 to the product.
24 x 32 = 768
768 + 232 = 1000

Answer:
hope it helps you.......
The required slope of the line passing through the points is m = 9/2. Option A is correct.
Given that,
To determine the slope of the line that passes through the points (2, −3.5) and (4, 5.5).
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the line passing through two points is given by,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute value in the above equation
m= 5.5 +3.5 / 4 - 2
m = 9 / 2
Thus, the required slope of the line passing through the points is m = 9/2. Option A is correct.

The function f(t)=^ - 16t^ 2 +84t models the height of a ballt seconds after it was kicked straight up into the air. How many seconds does it take the ball to hit the ground ?
Answer:
5.25 seconds
Step-by-step explanation:
When the ball hits the ground the height is zero
Equate f(t) to zero and solve for t , that is
- 16t² + 84t = 0 ← factor out - 4t from each term
- 4t(4t - 21) = 0
Equate each factor to zero and solve for t
- 4t = 0 ⇒ t = 0
4t - 21 = 0 ⇒ 4t = 21 ⇒ t = [tex]\frac{21}{4}[/tex] = 5.25
t = 0 is the time when the ball is kicked
t = 5.25 is the time taken for the ball to hit the ground
