Since the lines a and b are parallel, the corresponding angles <1 and <5 are congruent, therefore angle <5 measures 80°.

Angles <6 and <7 are supplementary angles to angle <5, so we have:

So the sum of <6 and <7 is:

Therefore the answer is 200.

Given:

U = {1, 2, 3, 4, 5, 6, 7, 8, 9}

A = {1,2,3,4,5}

B = {4, 5, 6, 7}

C = {5, 6, 7, 8, 9}

D= {1, 3, 5, 7, 9}

E= {2, 4, 6, 8}

F = {1, 5, 9}

What is the question: Find AUC'.

Recall the following:

A ∩ C (read as A intersection C) - are members that are common to both set A and set C.

A ∪ C (read as A union C) - are members that are in set A or set C or both, combining the members of all sets.

C' (read as C complement) - are members that are not in the universal set.

Since what we are about to find is A ∪ C', let's first determine the members of C'.

We get,

C' = {1, 2, 3, 4}

A = {1,2,3,4,5}

Therefore, AUC' = {1,2,3,4,5}.

The distance between the points where the points are given as [tex](5\frac 78, -\frac 12)[/tex] and [tex](9\frac 34, -\frac 12)[/tex] is 3.875 units

The points are given as

[tex](5\frac 78, -\frac 12)[/tex] and [tex](9\frac 34, -\frac 12)[/tex]

The distance between the points is calculated as

d  = √(x₁ - x₂)² + (y₁ - y₂)²

Where x and y are the coordinate points and d is the distance

Substitute the known values in the above equation

So, we have

[tex]d = \sqrt{(5\frac 78 - 9\frac 34)\² + (-1/2 + 1/2)\²[/tex]

Evaluate the sum in the above equation

So, we have

[tex]d = \sqrt{(5\frac 78 - 9\frac 34)\²[/tex]

Evaluate the exponents in the above equation

So, we have

[tex]d = (-5\frac 78 + 9\frac 34)[/tex]

Evaluate the difference  in the above equation

So, we have

d  = 3.875

Hence, the distance between the points is 3.875 units

The linear equation that passes through (-2, 11) and (1, -4) is:

y = -5*x + 1

The general linear equation is:

y = a*x +b

Where a is the slope and b is the y-intercept.

If the line passes through points (x₁, y₁) and (x₂, y₂) then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Here we know that the line passes through the points (-2, 11) and (1, -4), then the slope is:

a = (-4 - 11)/(1 + 2) = -15/3 = -5

y = -5*x + b

To find the value of b, we use one of the two given points, here i will use (1, -4), it gives:

-4 = -5*1 + b

-4 + 5 = b

1 = b

So the linear equation is:

y = -5*x + 1

Answer:

The probability that you will win the top prize and your best friend wins the second prize is 1/870.

In decimal form, this is 0.001149.

In percent form, this is approximately 0.11%.

Answer:

196 = y

Step-by-step explanation:

If o is 140, the value of y is what? 28 ✕ o = 20 ✕ y

28 ✕ o = 20 ✕ y

28 ✕ 140 = 20 ✕ y

3,920 = 20✕ y

right side: 20 is multiplied by y and can be written back to back:

3,920 = 20y

divide both sides by 20:

3,920/20 = 20y/20

196 = y

First we need to look at the change of signal of the function (it changes from √x to -√x).

This change of signal means the function was reflected over the x-axis.

Then, the value of -3 was added to the function.

An addition of -3 in the function means a translation of 3 units down.

So the transformations from m(x) to p(x) are:

A reflection over the x-axis followed by a translation of 3 units down.

When z = 9 and x = 4, and y = 360. then, with x = 4 and z = 9, we obtain the value of y = 600.

According to question, given that

x = 4, z = 9 , y = 360

The value of y varies jointly with the values of x and z then

Joint variation ⇒ y = k. x. z , where k is constant. In all cases when k ≠ 0

360 = k (4) (9)

360 = 36 k

k = 360/36

k = 10

y = k. x. z

y = 10 .x . z

when x = 5 and z = 12 then

y = 10 .x . z

y = 10 (5) (12)

y = 600

Therefore,  When x=4 and z=9, and the value of y is 360. then we get the value of y = 600, when x=4 and z=9 using joint variation.

Any number of issues involving rates, times, and work can be resolved rationally. Rational formulas include direct, inverse, and joint variation equations. In direct variation, the variables are directly related to one another; as one quantity rises, the other will as well.

Then, the stock lose $1 in value ($-1)

Answer:

your answer is C

Step-by-step explanation:

by elimination B is not possible as the graph shows a cubic shape B has no cubic terms, D is not possible because the graph shows a translation on X axis and D represents a translation in Y axis, and A is not possible because when X=0 the value of Y must be -64 and A doesn't comply to that.

Answer:

C

Step-by-step explanation:

the graph has 3 zero solutions (values of x with y = 0).

therefore it has to be of 3rd degree (3 is the max. exponent of x).

that eliminates B, because it is only of 2nd degree.

when x = 0, y is a little bit below -60 but above -80.

but y is negative.

that eliminates A, because when x = 0, y = +64.

for x = -8, y has to be 0 too.

that eliminates D, because for x = -8, y = -8³ - 64 = -512 - 64 = -576

and not 0.

so, C must be correct.

for x = 0, y = -64

for x = -8, y = -8³ + 6×-8² - 24×-8 - 64 =

= -512 + 6×64 + 192 - 64 =

= -512 + 384 + 192 - 64 = 0

for x = -2, y = -2³ + 6×-2² - 24×-2 - 64 =

= -8 + 6×4 + 48 - 64 =

= -8 + 24 + 48 - 64 = 0

for x = 4, y = 4³ + 6×4² - 24×4 - 64 =

= 64 + 6×16 - 96 - 64 =

= 64 + 96 - 96 - 64 = 0

all fits.

F(x) = K• (b)^x

The value of cos (A - B) will be 33/65.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The values are;

cos A = 24/25

And, sin B = 63/65

Now,

cos (A - B) = cos A cos B + sin A sin B

Since, cos A = 24/25

So, sin A = 7/25

And, sin B = 63/65

So, cos B = 16/65

Substitute all the values, we get;

cos (A - B) = cos A cos B + sin A sin B

               = 24/25 x 16/65 + 7/25 x 63/65

              = 384/1625 + 441 / 1625

              = 825 / 1625

              = 33/65

Angle A = 19°

Explanation

Vertical angles are angles that are directly opposite each other at a point where two lines intersect or cross each other. Vertical angles are known to be equal to each other.

So, Angle A = Angle B

Angle A = 3x + 13

Angle B = 5x + 9

3x + 13 = 5x + 9

We can rewrite this as

5x + 9 = 3x + 13

5x - 3x = 13 - 9

2x = 4

Divide both sides by 2

(2x/2) = (4/2)

x = 2

Angle A = 3x + 13 = 3(2) + 13 = 6 + 13 = 19°

The number of cheeseburgers sold was three times the number of hamburgers sold then 79 hamburgers and 237 cheeseburgers were sold on Sunday.

Let h be the number of hamburgers

c be the number of cheeseburgers

A local hamburger shop sold a combined total of 316 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold.  

h + c = 316

c = 3h

h + 3h = 316

simplifying the above equation, we get

⇒ 4h = 316

Dividing both sides of the equation by 4, we get

⇒ 4h / 4 = 316 / 4

⇒ h = 79

Therefore, hamburgers were sold on Saturday is 79.

The number of cheeseburgers sold was three times the number of hamburgers sold then

c = 3h

substitute the value of h in the above equation, we get

⇒ c = 237

Therefore, 79 hamburgers and 237 cheeseburgers were sold on Sunday.
