Answer:

The radius of the circle is 5 units

Step-by-step explanation:

Given in the question,

centered point = (-3 , 2)

a point in the circle = (1,5)

To find the radius of circle we will use the circle equation

(x – h)² + (y – k)² = r²,

with the centre being at the point (h, k) and the radius being r.

Plug values in the equation

(1 – (-3))² + (5 – 2)² = r²

(1+3)² + (3)² = r²

4² + 3² = r²

25 = r²

r = √25

r = 5

Answer:

The answer is 2.333 yards

Step-by-step explanation:

In every one yard there's thirty-six inches.

84/36= 2.333

Hope this helps :)

To convert 84 inches to yards, first convert inches to feet by dividing by 12, resulting in 7 feet. Then, convert feet to yards by dividing by 3, resulting in approximately 2.33 yards.

To convert 84 inches to yards, we need to use the relationships between inches, feet, and yards.

Start by converting inches to feet, and then convert feet to yards.

1. Convert inches to feet:

There are 12 inches in a foot, so divide the number of inches by 12.
84 ÷ 12

= 7 feet

2. Convert feet to yards:

There are 3 feet in a yard, so divide the number of feet by 3.
7 ÷ 3

= 2.33 yards

Thus, 84 inches is equal to approximately 2.33 yards.

Answer:

The correct option is B.

Step-by-step explanation:

If polar coordinates of point P are

[tex]P=(r,\theta)[/tex]

Where, r is real number and θ is in radian, then all polar coordinates of point P are defined as

[tex]P=(r,\theta+2n\pi)[/tex]

[tex]P=(-r,\theta+(2n+1)\pi)[/tex]

The given coordinates are [tex]P(5,-\frac{\pi}{6})[/tex]. So, all polar coordinates of point P are

[tex]P=(5,-\frac{\pi}{6}+2n\pi)[/tex]

[tex]P=(-5,-\frac{\pi}{6}+(2n+1)\pi)[/tex]

Therefore correct option is B.

Answer:

The slope is .075 and the y intercept is -.125

Step-by-step explanation:

8y = .2(3x -5)

Distribute the .2

8y = .6x - 1

Divide by 8

8y/8 = .6x/8 -1/8

y = .075x -.125

This is in slope intercept form  y= mx+b  where m is the slope and b is the y intercept.

The slope is .075 and the y intercept is -.125

[tex]\bf \textit{arc's length}\\\\ s=\cfrac{\theta \pi r}{180}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ r=6\\ \theta =45 \end{cases}\implies s=\cfrac{(45)\pi (6)}{180}\implies s=\cfrac{3\pi }{2}\implies s\approx 4.7[/tex]

Step-by-step explanation:

Overall without stating all the steps, it'd be 2.

Answer:

x =  ±sqrt(19)

Step-by-step explanation:

x^2-8=11

Add 8 to each side

x^2-8+8=11+8

x^2 = 19

Take the square root of each side

sqrt (x^2) = ±sqrt(19)

x =  ±sqrt(19)

Answer:

See picture attached.

Step-by-step explanation:

To find the solution, graph each equation using the y = mx + b form.

Start by converting to this form.

x + 2y < 4 becomes y < -1/2x +2

3x - y > 2 becomes y < 3x - 2

Then mark each y-intercept. These points are (0,2) and (0,-2).

Using the slope mark the next points at (-1,4) and (1, -1) respectively.

Connect using dash lines since this is not equal to in either inequality.

Test a point no on either line like (-1,-1).

If the inequality holds true, shade the area.

Where the areas overlap is the solution. See picture.

Inequalities are used to represent unequal expressions.

The solution to the inequality is [tex]x \le \frac 87[/tex] and [tex]y < \frac{10}7[/tex]

The inequalities are given as:

[tex]x + 2y \le 4[/tex]

[tex]3x - y > 2[/tex]

Express both inequalities as equations'

[tex]x + 2y = 4[/tex]

[tex]3x -y = 2[/tex]

Make y the subject in [tex]3x -y = 2[/tex]

[tex]y = 3x - 2[/tex]

Substitute [tex]y = 3x - 2[/tex] in [tex]x + 2y \le 4[/tex]

[tex]x + 2(3x - 2) \le 4[/tex]

Open brackets

[tex]x + 6x - 4 \le 4[/tex]

[tex]7x - 4 \le 4[/tex]

Collect like terms

[tex]7x \le 4+4[/tex]

[tex]7x \le 8[/tex]

Divide both sides by 7

[tex]x \le \frac 87[/tex]

Substitute 8/7 for x in [tex]3x - y > 2[/tex]

[tex]3 \times \frac 87 - y > 2[/tex]

[tex]\frac{24}7 - y > 2[/tex]

Collect like terms

[tex]- y > 2 -\frac{24}7[/tex]

Take LCM

[tex]- y > \frac{14 -24}7[/tex]

[tex]- y > \frac{-10}7[/tex]

Divide both sides by -1

[tex]y < \frac{10}7[/tex]

Answer:

The length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Step-by-step explanation:

We are given the length (l) = 8, width (w) = 4 and height (h) = 2.

Now we have to find the diagonal of the base.

The given figure is a rectangle box. The base of the rectangular box is a rectangle with the length (l) = 8 and the width(w) = 4

The length of the diagonal (d) = [tex]\sqrt{l^2 + w^2}[/tex]

d = [tex]\sqrt{8^2 + 4^2}[/tex]

d = [tex]\sqrt{64 + 16}[/tex]

d = [tex]\sqrt{80}[/tex]

d = [tex]\sqrt{16} \sqrt{5}[/tex]

d = 4[tex]\sqrt{5}[/tex]

So, the length of the diagonal (d) = 4[tex]\sqrt{5}[/tex] units.

Answer:

The Answer is 156

Step-by-step explanation:

A=(B1+B2)H/2

1) to find the area of a trapezoid you must First add the 2 bases

20+32= 52

2) Then Multiply the 2 bases sum by the Height

52 x 6 = 312

3) divide the product 312 By 2

312/2= 156

That is Your answer!

Hopes this helps!

For the area of a trapezoid use formula: Area = (BaseX+BaseY) times Height divided by 2.

so for this problem you’d plug in (20+32) times 6 then divide it by two.

20+32=52 times 6 equals 312

Divide by 2 and you get 156.

Answer:

Step-by-step explanation:

x - 5 = 7

⇒ x = 7 + 5 = 12

To solve for x, add 5 to both sides of the equation and then determine the absolute value of x.

To solve for x in the equation |x| – 5 = 7, we need to isolate x on the left side of the equation. To do this, we can add 5 to both sides:

|x| – 5 + 5 = 7 + 5

|x| = 12

Now, we have an absolute value equation. The absolute value of a number is its distance from zero. Therefore, we have two possible solutions: x = 12 or x = -12.

Answer:

$2.50

Step-by-step explanation:

Let's take a look at the 4 orders and check the price per pup cake in each order:

Order 1: $5 for 2 cakes, so $2.50 per cake.

Order 2: $7.50 for 3 cakes, so $2.50 per cake.

Order 3: $12.50 for 5 cakes, so $2.50 per cake.

Order 4: $20.00 for 8 cakes, so $2.50 per cake.

Jake has a very consistent pricing of his cakes... they're always $2.50 each.

That price is the relation between the price asked and the number of cakes sold, that's the constant of proportionality in this case.

Answer:

Option 3rd is correct

$2.5 is the constant of proportionality in cost per pup cake

Step-by-step explanation:

The direct proportionality states that:

[tex]y \propto x[/tex]

then the equation is in the form of :

[tex]y = kx[/tex]              ....[1]

where, k is the constant of proportionality.

As per the statement:

The table shows how much Jake charged for the last 4 orders of pup cakes.

Let y represents the cost  and x represents the pup-cakes

Consider any values of x and y from the given tables.

x = 3 and y = $7.5

To find constant of proportionality in cost per pup cake.

Substitute these in [1] we have;

[tex]7.5 = 3k[/tex]

Divide both sides by 3 we have;

2.5 = k

or

k = 2.5

Therefore, $2.5 is the constant of proportionality in cost per pup cake

The answer to this is B, because supplementary angles sum up to 180 degrees, which means it is a straight angle.

Answer:

Option B and D

Step-by-step explanation:

Given are four options and we have to select the one which form a straight angle.

The given options are

A. Vertical Angles  ... Vertical angles are formed when two lines intersect and hence cannot combine to form a straight angle.  Incorrect option.

B. Supplementary Angles ... Supplementary angles are a pair of angles which add upto 180 degrees and hence they form a straight angle. Correct option

C. Complementary Angles  ... These pair add up to 90 degrees and cannot combine to form a straight angle.  ..  Incorrect

D. Linear Pair ... A linear pair is a pair of angles formed on a straight line and hence correct option.

Three times two equals six

Another factor of 6, besides 6 and 1, is 3. Factors are numbers that divide into another number without leaving any remainder. Both 2 and 3 are factors of 6 since 2 multiplied by 3 equals 6.

Besides 6 and 1, another factor of 6 is 3.

Factors are whole numbers that divide evenly into another number. For the number 6, the factors are 1, 2, 3, and 6. The process of factoring involves finding all numbers that you can multiply together to get the number in question. In this case, 2 multiplied by 3 equals 6.

We can also verify this by noting that dividing 6 by 3 gives us 2 with no remainder, confirming that 3 is indeed a factor of 6.
