Answer:

8 units

Step-by-step explanation:

» Concepts

Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.

» Application

In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.

» Solving

Step 1: Subtract q from both sides.

Step 2: Add 8 to both sides.

Step 3: Divide both sides by 3.

Step 4: Plug in the value of q for side AB.

Therefore, the answer is 8 units.

Step-by-step explanation:

The area of the region which is inside the polar curve r = 5 sinθ but outside r = 4 will be 3.75 square units.

When the two curves intersect then they bound the region is known as the area bounded by the curve.

The area of the region which is inside the polar curve r = 5 sinθ but outside r = 4 will be

Then the intersection point will be given as

[tex]\rm 5 \sin \theta = 4\\\\\theta = 0.927 , 2.214[/tex]

Then by the integration, we have

[tex]\rightarrow \dfrac{1}{2} \times \int _{0.927}^{2.214}[ (5 \sin \theta)^2 - 4^2] d\theta \\\\\\\rightarrow \dfrac{1}{2} \times \int _{0.927}^{2.214} [25\sin ^2 \theta - 16] d\theta \\\\\\\rightarrow \dfrac{1}{2} \times \int _{0.927}^{2.214} [ \dfrac{25}{2}(1 - \cos 2\theta ) - 16] d\theta \\[/tex]

[tex]\rightarrow \dfrac{1}{2} [\dfrac{25 \theta }{5} - \dfrac{25 \cos 2\theta }{2} - 16\theta]_{0.927}^{2.214} \\\\\\\rightarrow \dfrac{1}{2} [\dfrac{25(2.214 - 0.927) }{5} - \dfrac{25 (\cos 2\times 2.214 - \cos 2\times 0.927) }{2} - 16(2.214 - 0.927]\\[/tex]

On solving, we have

[tex]\rightarrow \dfrac{1}{2} \times 7.499\\\\\rightarrow 3.75[/tex]

Thus, the area of the region is 3.75 square units.

Answer:

Step-by-step explanation:

The  coordinates of E(4a, 0).

A midpoint is a point in the middle of the line connecting two points that lies between them. The midpoint is a point that lies in the middle of the line and is equidistant from the two points if a line is drawn to connect them.

The midpoint between two points whose coordinates are known to us can be found using the midpoint formula. If we know the coordinates of the other endpoint and the midpoint, we can also use the midpoint formula to determine the coordinates of the endpoint.

Given coordinates

A(-3a, -2b),  D(a, -2b), C(5a, -2b) and B(3a, 2b)

to find the coordinates of E,

and E is midpoint of B and C

for coordinates of midpoint is (x, y) = [(x₂ + x₁)/2, (y₂ + y₁)/2]

here B  = (3a, 2b) = (x₁, y₁)

and C = (5a, -2b) = (x₂, y₂)

x = (5a + 3a)/2 = 8a/2 = 4a

y = (-2b + 2b)/2 = 0/2 = 0

E(4a, 0)

Hence coordinates of E are (4a, 0).

Answer:

Z = 1.25

Step-by-step explanation:

[tex]\displaystyle Z=\frac{\text{Observed Value}-\text{Mean of the Sample}}{\text{Standard Deviation of the Sample}}\\\\Z=\frac{x-\mu}{\sigma}\\ \\Z=\frac{87-82}{4}\\ \\Z=\frac{5}{4}\\ \\Z=1.25[/tex]

Hence, Michael's z-score is 1.25, which means that he scored 1.25 standard deviations above the class average.

Answer:

1134

Step-by-step explanation:

Formula for diameter=2 x r

(π is 3.14)

Formula for area= π x r^2

So all you basically have to do is go backwords with the first one then plug the radius into the second one normally

38/2=19

Now just plug it into your second equation

π x 19^2=1134.11494795

Step-by-step explanation:

A  no   = 1/5

B no   = 4

C  no   = 1/3

D   yes

E     no = 17/50

26/104

the correct option is 26/104 because if 26 divides 26/104 it will give 1/4 because

26÷26= 1

104÷26=4

therefore, the correct option is 26/104

The area of the rectangular roof (both sides of the roof) = 1,360 ft²

Cost to cover both sides = $1,020

The area of a rectangle = (length)(width)

Area of both sides of the roof = 2(area of rectangle) = 2(40×17) = 1,360 ft²

Cost to cover both sides = 1,360 × 0.75 = $1,020

Functions can be represented using equations and graphs Both f(x) and g(x) include domain values of [4, ∞) and range values of [0, ∞), and both functions have a y-intercept in common.

The domain of the function is defined as the set of the numbers we are allowed to put in the function while the range is the assumed data put in the function.

The functions are given as:

[tex]F(x)=e^{-x}\\\\\\g(x)=-\sqrt{x-4}[/tex]

Using a graphing calculator:

The domain of g(x) is [4, ∞)

The range of g(x) is  [0, ∞)

The domain of f(x) is  (–∞, ∞),

The range of f(x) is  [0, ∞)

Both functions have positive values for their domains

Answer:

x = 2 ; y = 12

Step-by-step explanation:

2x + 3y = 40

+ -2x +2y = 20

You solve for one of the variables by cancelling out one and making one the subject.

2x + 3y = 40.

+ -2x +2y = 20

5y = 60

5y/5 = 60/5

y = 12

Next, you solve for X by replacing the value of y in any of the equations.

2x + 3y = 40

2x + 3(12) = 40

2x + 36 = 40

2x = 40 - 36

2x = 4

2x/2 = 4/2

x = 2

To prove the equations are set, replace the values of X and Y in one of the equations.

2x + 3y = 40

2(2) + 3(12) = 40

4 + 36 = 40

40 = 40

Answer:

Step-by-step explanation:

Simplifying

2x + 13 = 0

Reorder the terms:

13 + 2x = 0

Solving

13 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + 2x = 0 + -13

Combine like terms: 13 + -13 = 0

0 + 2x = 0 + -13

2x = 0 + -13

Combine like terms: 0 + -13 = -13

2x = -13

Divide each side by '2'.

x = -6.5

Simplifying

x = -6.5

Explanation:

The x coordinates of points A and B are 2 and -2 respectively. Add them up and divide by 2 and we would get (A+B)/2 = (2+(-2))/2 = 0/2 = 0.

The x coordinate of the midpoint is 0.

The y coordinate of the midpoint follows the same idea, but we focus on the y coordinates of course. You should find the y coordinate of the midpoint is 0.

The midpoint is at (0,0) as the diagram shows.

Step-by-step explanation:

the upper (smaller) triangle and the complete triangle are similar.

that means the angles in both triangles are the same. and the lengths of all corresponding pairs of sides correlate with the same scaling factor.

therefore,

(8x - 10) / (8x - 10 + 18) = 25 / (25 + 15)

(8x - 10) / (8x + 8) = 25 / 40 = 5/8

8(8x - 10) = 5(8x + 8)

64x - 80 = 40x + 40

24x = 120

x = 5

They will work 4 hours to get same amount of saving

Answer:

4 hours

Step-by-step explanation:

First, create a linear equation for Carlos using the graph.

Two points on the line:  (0, 2) and (1, 10)

[tex]\implies \sf slope\:(m)=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{10-2}{1-0}=8[/tex]

Use the point-slope equation with the found slope and one of the points:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-2=8(x-0)[/tex]

[tex]\implies y=8x+2[/tex]

Now equate the equations for Mary Ann and Carlos, and solve for x:

[tex]\implies 6x+10=8x+2[/tex]

[tex]\implies 8=2x[/tex]

[tex]\implies x=4[/tex]

Therefore, Mary Ann and Carlos have saved the same amount after 4 hours work.
