(r,θ) = (x,y)
x = r * cosθ
y = r * sinθ
Since your θ is 5π3, set your calculator to radians before taking the sine and cosine.

(3* 1 / 2, 3 * - sqrt(3) / 2)

if r = -3, then x is negative, y is positive.

Which of the following is NOT equivalent to 78 ÷ 6? (72 + 6) ÷ 6 (72 ÷ 6) + (6 ÷ 6) (60 ÷ 6) + (18 ÷ 6) (72 ÷ 6) + 6

Answers

Answer:

(72 divided by 6) + 6

Step-by-step explanation:

78 divided by 6 is 13. The question (72 divided by 6) + 6 does not equal to 13, it equals to 14, therefore (72 divided by 6) + 6 is not equivalent.

Answer:

(72 divided by 6) + 6

What would you multiply to make the y variable cross out?

-5x + y = -3

3x - 8y = 24

Answers

Answer:

Step-by-step explanation:

-40x + 8y = -24

3x - 8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24 (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

simplify and find each side

2.23606798 x 2 = 4.47213596

-------

4.47213596

4.47213596^2 + 4.47213596^2 = 8.94427192^2

Order from least to greatest.
68%, 0.687, 20

Answers

Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

What is the slope of this line?

Answers

Answer:

A line is increasing if it goes up from left to right. The slope is positive, i.e. m > 0 {\displaystyle m>0} .

A line is decreasing if it goes down from left to right. The slope is negative, i.e. m < 0 {\displaystyle m<0} .

If a line is horizontal the slope is zero. This is a constant function.

If a line is vertical the slope is undefined (see below).

x = 4

y = 5

Step-by-step explanation:

4x = x + 12

^(subtract x from both sides)^

3x = 12

^(divide both sides by 3)^

x = 4

3y = 15

(divide both sides by 3)

y = 5

13 ,85

Answers

Answer:

Step-by-step explanation:

I just use an online calculator.-

www.calculator.net/triangle-calculator

Let perpendicular = x and base = 13
So, P² = H² - B²
Or, x² = 85² - 13²
Or, x² = 7225 - 169
Or, x² = 7056
i.e x = = 84

What is rotation?

Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.

Given:

LMNP is rotated 90° clockwise around the origin.

If we rotate the figure in LMNP about 90 degrees then the coordinates will change into

(x, y) to (y, -x).

As, x= 3, y=4

Hence, the coordinates of M is M’(4,-3).

Answer:

15.08 m

Step-by-step explanation:

You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.

Angle XZW is 180° -108° = 72°

The circumference is C=πd, so the arc of interest is ...

XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m

XW ≈ 15.08 m

_____

If you use π = 3.14, then your answer will be 15.07 m.
