Answer:

Quadrant IV or D

Step-by-step explanation:

It is Quadrant IV or D, since it is a positive x (meaning it must be 1 or 4) and it has a negative y (so 3 or 4). You then find the common answer which is 4 or IV.

Answer:

57 + x = 360

-57         -57

X = 303 degrees

Step-by-step explanation:

Full circle equals 360 degrees

Given degree is 57

Unknow value will be replaced as x

Unknown value(x) and given degree added together willl equal 360 degrees in total:

57 + x = 360

Answer:

$34.56

Step-by-step explanation:

First, find the discount price.

20% of 40

20/100 x 40= $8

Deduct the discount from the original price.

40 - 8 = $32

This is the discount price.

Now, find 8% (tax) of the price.

8/100 x 32 = $2.56

Add it to the price.

32 + 2.56 = $34.56

Hope this helps!

Answer:

C) [tex]\sqrt{106}[/tex] units

Step-by-step explanation:

The Pythagorean Theorem is [tex]a^2+b^2=c^2[/tex] where [tex]a[/tex] and [tex]b[/tex] are side lengths of a right triangle and [tex]c[/tex] is the hypotenuse, the longest side of the right triangle.

The distance formula is similar to that of the Pythagorean Theorem which is [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points that you wish to find the distance between them in an (x,y) coordinate plane.

Here, we are given that [tex](x_1,y_1)[/tex] is [tex]P(-4,-6)[/tex] and [tex](x_2,y_2)[/tex] is [tex]Q(1,3)[/tex]. So, we can use the distance formula as described previously to find the positive distance between the two points:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]d=\sqrt{(1-(-4))^2+(3-(-6))^2}[/tex]

[tex]d=\sqrt{(1+4)^2+(3+6)^2}[/tex]

[tex]d=\sqrt{(5)^2+(9)^2}[/tex]

[tex]d=\sqrt{25+81}[/tex]

[tex]d=\sqrt{106}[/tex]

[tex]d \approx 10.295630141[/tex]

Since all of the given answer choices are in radical form, then C is the correct answer. The distance between the two points is [tex]\sqrt{106}[/tex] units.

Answer:

193

Step-by-step explanation:

Let's "cheat" a little on this one

We know that the numbers are consecutive

so lets take the square root of 9312 to get close

√9312 = 96.4987046545

Consecutive numbers around 96.4987046545

96 * 97 = 9312

96 + 97 = 193

-------------------------------

The "correct" method would be to set up an equation

x(x + 1) = 9312

x² + x = 9312

x² + x - 9312 = 0

Then use the quadratic equation to solve for x

Which you can do if you're so inclined.

Me, I'm happy to have "cheated"

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

In order to calculate the slope of a line, we must plot two points on the line.

One point will be [tex](-3,2)[/tex] and another point will be [tex](1,4)[/tex]

Then use the slope formula to identify the slope of the line.

[tex]m=\frac{y^1-y^2}{x^1-x^2}[/tex]

[tex]m=\frac{2-4}{-3-1}[/tex]

[tex]m=\frac{-2}{-4}[/tex]

[tex]m=\frac{2}{4}[/tex]

[tex]m=\frac{1}{2}[/tex]

The slope of the line is [tex]\frac{1}{2}[/tex]

You have the right idea so far, but you forgot to finish it up.

Point slope form is

y - y1 = m(x - x1)

where m is the slope, and (x1,y1) is the point the line goes through. As you can see, we have infinitely many choices for (x1,y1). If you use the y intercept point (0,5), then

y - y1 = m(x - x1)

y - 5 = -1(x - 0) ..... this is one of infinitely many possible answers

OR

If you use the point (2,3), then we'd say

y - y1 = m(x - x1)

y - 3 = -1(x - 2) ..... which is another possible answer

There are infinitely many other choices, but I'm only picking the points in which your teacher has shown as big dots.

By the way, nice work on getting the correct answer for the slope-intercept form.

Step-by-step explanation:

(0,5)and (2,3)

[tex] m = \frac{y1 - y2}{x1 - x2} \\ = \frac{5 - 3}{0 - 2} \\ = - 1 \\ \\ m = - 1 \\ substitude (0,5)or (2,3) \\ substitude \: (0,5)for \: convenience \\ y = - 1x + b \\ 5 = b \\ y = - x + 5[/tex]

Answer:

$455.4 For The Year

Step-by-step explanation:

Kevin  pays $ 37.95 per month for his cell phone with unlimited minutes

First, We know that there are 12 months in 1 year.

Therefore, 1 year = 12 months

The cost per month = $ 37.95

So, have to find the cost for 12 months

Cost for 12 months = 12 x 37.95

Cost for 12 months = 455.4

So your solution to the problem is $455.4 Cost for the year.

Answer:

Step-by-step explanation:

If AB is tangent to the circle, the AB makes a right angle with the radius BC. That means that triangle ABC is a right triangle and we need Pythagorean's Theorem to find the missing side which is the hypotenuse.

[tex]AC^2=AB^2+BC^2[/tex] and filling in:

[tex]AC^2=14^2+9^2[/tex] and

[tex]AC^2=196+81[/tex] and

[tex]AC^2=277[/tex] so

[tex]AC=\sqrt{277}[/tex] ≈ 16.64

AC = 16.64

"It states that a line is a tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency."

From given diagram,

tangent AB = 14 units

radius BC = 9 units

Using tangent theorem,

AB is perpendicular to BC.

This means ΔABC is right triangle with ∠B = 90°

Using Pythagoras theorem,

[tex]AC^2=AB^2+BC^2[/tex]

⇒ [tex]AC^2=14^{2}+9^{2}[/tex]

⇒ [tex]AC^2=196+81[/tex]

⇒ [tex]AC^2=277[/tex]

⇒ [tex]AC=\sqrt{277}[/tex]

⇒ [tex]AC=16.64[/tex]

Therefore, AC = 16.64

Answer:

opción D

Step-by-step explanation:

El número más bajo es -2

Número mayor que -2 es -1

Número mayor que -1 es 0

Número mayor que 0 es 4

Entonces, el orden de mayor a menor es 4> 0> -1> -2

Por tanto, la opción D es correcta

Step-by-step explanation:

for the perimeter...

18-6=12

that's to get the slant side

perimeter=10+6+12+12+20

=60

for the area I'm not sure how to solve it sorry!!

Answer:

10 x 6 = 60

20 + 10 = 30, 30 x 12 x 1/2 = 180

180 + 60 = 240 cm2 is your area

6 + 6 = 12, 12 + 10 = 22, 22 + 20 = 42

Now lets find hypotenuse:

10 - 20 = 10, 10 divided by 2 = 5

5^2 + 12^2

25 + 144 = 169

Square root of 169 is 13

Add perimeters:

42 + 13 = 55 cm is your perimeter.

Answer:

[tex]Change = \$36[/tex]

Step-by-step explanation:

Given

See attachment for line plot

[tex]Amount = \$100[/tex]

Required

Determine the change

First, we calculate the amount represented by the line plot

[tex]Amount (Plot) =10+12+12+14+16[/tex]

[tex]Amount (Plot) =64[/tex]

The change from $100 is then calculated as:

[tex]Change = Amount - Amount (Plot)[/tex]

[tex]Change = \$100 -\$64[/tex]

[tex]Change = \$36[/tex]
