Answer:

x-coordinates of point B = 3

Step-by-step explanation:

If the extreme ends of a segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], coordinates of the midpoint of the given segment will be = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Coordinates of the extreme ends of segment AC are A(-2, -3) and C(8, -3).

Since B is a point that bisects the segment AC, coordinates of point B will be,

= [tex](\frac{-2+8}{2},\frac{-3-3}{2})[/tex]

= (3, -3)

Therefore, x-coordinates of the point B will be = 3

Answer:

the answer is 57.12

Step-by-step explanation:

so the area of the rectangle is 74.24, thats where you get the 8 x 9.28, which is important. so next we're going to go is 9.28-5 which equals 4.28, and that is what the total bottom of 2 triangles would be, (if you drew a rectangle around it). the you would divide 4.28 by 2 to get 2.14, which is the value of 1. next you do 2.14 x 4 and get 8.56. then divide 8.56 by 2 and get back to 4.28. you take 4.28 and multiply it by 4 to get 17.12. from there on you do, 74.24 - 17.12 and get 57.12.

Step-by-step explanation:

Answer:

B. No solutions

Step-by-step explanation:

y= -3x + 9

3y = -9x + 9

Rewrite the first equation below. Then, divide both sides of the second equation by 3 and write it below the first equation.

y = -3x + 9

y = -3x + 3

Now look at the two equations. They are both written in the slope-intercept form, y = mx + b, where m = slope, and b = y-intercept. They have the same slope (m = -3) and different y-intercepts (9 and 3), so they are equations of two different lines, but since the slopes are the same, the lines are parallel. Since the lines never intersect, there is no solution.

Answer:

7/10

Step-by-step explanation:

20 balls.

10 even, 10 odd.

4 numbers less than 5.

That is 14/20 --> 7/10

Most likely.

Probability that the ​number on the ball drawn will be even or less than 5

= 3/5

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Given,

Total no. of balls = 20

All balls are numbered with numbered 1 through 20.

Balls with even numbers or less than five:

1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20

No. of balls with even numbers and less than five = 12

Probability that the ​number on the ball drawn will be even or less than 5 = No. of balls with even numbers or less than five/Total balls

                  = 12/20

Probability = 3/5

Hence, 3/5 is the probability that the ​number on the ball drawn will be even or less than 5.

Answer: The sales tax is $36.79  

Step-by-step explanation:

Multiply the sales tax percent by the money to find how much the sale tax is.

7% * 525.50 = 36.785  which rounds to 36.79  to the nearest penny.

The required amount of sales tax for the refrigerator is $36.785.

As mentioned in the question, a refrigerator is priced at $525.50. There is a 7% sales tax rate. The sales tax for the refrigerator in dollars and cents is to be determined.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
The total price of the sales tax = $525.50
Sales tax is 7%,

sales tax= 525.50 × 7%
sales tax = $36.785

Thus, the required amount of sales tax for the refrigerator is $36.785.

Answer:

750 rupees is used to make shirt

250 rupees is profit

Step-by-step explanation:

If the retailer sold the shirt for 1000 rupees and got 25% profit then that means 1/4 is profit and 3/4 is how much the retailer spent to make the shirt.

So 1000 times 3/4 is 750 which is how much the shirt really cost and

1000 times 1/4 is 250 and that is the retailers profit.

g(x) = 7x + 13.

Find g(f(3))

Find f(3) = 3^2+4 = 9+4 = 13

Then find g(13) = 7*13 + 13 = 91+13 = 104

Answer:

The correct value is 720 ft of fencing.

Answer:

Max Area = 64800 sq.ft

Step-by-step explanation:

A square will always give us the maximum area.

Thus, one side would be;

720/4 = 180 feet

So, we want a square 180 ft by 180 ft

however, from the question, we are to use the creek as one side. So, we'll take the 180 ft that we don't need because of the creek and then add it to the opposite side to get 180 + 180 = 360 ft.

Thus,we now have a rectangle with dimensions: 180 ft by 360 ft

Area is given by;

area = length × width

Maximum Area = 180 × 360

Max Area = 64800 sq.ft

When you create the number line, put 0 in the middle. Basically you put all the numbers you got from least to greatest on the number.

Since -3/2 is less than 0, it will go to the left of 0.

Since 3/2 and 5/2 are greater than 0, it will go to the right of 0.

Remember to use sub points of 1.

According to cofunctions identities:

[tex]\boxed{\sin(90\º - \theta)=\cos(\theta)}[/tex]

[tex]\boxed{\cos(90\º - \theta)=\sin(\theta)}[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{ \tan(\theta)}{1+ \tan^2(\theta)}$[/tex]

Once

[tex]$\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)} $[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{1+ \frac{\sin^2(\theta)}{\cos^2(\theta)}}$[/tex]

Take

[tex]$1+\frac{\sin^2(\theta)}{\cos^2(\theta)}}=\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} $[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{ \frac{\sin(\theta)}{\cos(\theta)}}{\frac{\sin^2(\theta) + \cos^2(\theta)}{\cos^2(\theta)} }}$[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)}{\cos(\theta)} \cdot \frac{\cos^2(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)\cos(\theta)}{\sin^2(\theta) + \cos^2(\theta)} }$[/tex]

Once

[tex]\boxed{\sin^2(\theta) + \cos^2(\theta)=1}[/tex]

[tex]$\cos(\theta) \sin(\theta) = \frac{\sin(\theta)\cos(\theta)}{1 }$[/tex]

[tex]$\cos(\theta) \sin(\theta) = \sin(\theta)\cos(\theta)$[/tex]

The correct option are;

On a coordinate plane, a cubic function has an x-intercept of (0, 0)

On a coordinate plane, an oval is in quadrant 1

Step-by-step explanation:

Rotational symmetry of a shape is a shape that when it is rotated on its axis to a given angle less than one complete revolution, the shape looks exactly like the pre-image or original appearance of the shape

For a cubic function that has x-intercept = (0, 0) we have;

y = f(x) = a·x³ + b·x² + c·x

Has the shape f a fan blade and therefore, looks the sane when rotated when rotated through 180°

The shape of an oval looks the same when rotated through 180°
