Determine two pairs of polar coordinates for the point (5, 5) with 0Á _ _ < 360Á
Answers
5=rsin(Pi/4)=r . sqrt(2)/2, so r =10/sqrt(2)=10sqrt(2)
finally the polar coordinates are (r, teta) = (10sqrt(2), Pi/4)

BCDE is rotated 180° clockwise to form PQRS.
JKLM is rotated 180° clockwise to form BCDE.
JKLM is rotated 180° counterclockwise to form BCDE.
Answers
The transformations that took place are;
A: BCDE is rotated 180° counterclockwise to form JKLM.
B: BCDE is rotated 180° clockwise to form PQRS.
What is the transformation that took place?
We can see that the coordinates of Rectangle BCDE are;
B(2, 1); C(2, 2); D(4, 2); E(4, 1)
Now, for Rectangle JKLM, we see that the coordinates are;
J(-2, -1); K(-2, -2); L(-4, -2); M(-4, -1).
Now, for Rectangle PQRS, we see that the coordinates are;
P(-2, 1); Q(-2, 2); R(-4, 2); S(-4, 1).
We see the transformation from BCDE to JKLM as (x, y) → (-x, -y) and this is reflection over the x-axis which is 180° counterclockwise.

county X?
A a parallelogram with a base of 25 miles and a height of 25 miles
B a rectangle that is 15 miles long and 45 miles wide
C a right triangle with a leg that is 30 miles long and a hypotenuse that is
50 miles long
D a trapezoid with base lengths of 10 miles and 30 miles and a height of
25 miles
Answers
Answer:
Option C. is the correct option.
Step-by-step explanation:
County X has a population density of 250 people per square mile.
Total population of the county is 150000.
Total area which represents the population = =
square mile.
So geometric model which has the same area as 600 square miles will be the answer.
A). Area of a parallelogram = Base × height
= 25×25
= 625 square miles
which is not equal to 600 square miles so it's not the correct option.
B). Area of a rectangle = Length×width
= 15×45 = 675 square miles ≠ 600 square miles
Therefore, not the correct option.
C). Area of a right triangle =
Since length of hypotenuse is given so we will find the length of height.
Height = √[(Hypotenuse)²- (Base)²] =
=
=
= 40 miles
So area of the right triangle =
=
= 600 square miles
Which matches the area of County X, so it's a correct option.
D). area of trapezoid =
=
=
= 20×25
= 500 square miles ≠ 600 miles
Therefore, this option is not correct.

Step-by-step explanation:
1) I know that the equation for slope is y2-y1/x2-x1. For number one I first found two points of the graph which is (0,3) and (2,4) (not sure if I see it correctly, its kind of blurry). I decided that (0,3) would be my y1 and x1 and (2,4) will be my y2 and x2. I later plugged the number in the equation and got 4-3/2-0 which the answer turns out to be 1/2.
2) For the rest of the questions it is kinda the same business as question 1. For question two I chose two points out of the table which wrer (-1, -12) and (1,-8) and plugged them into the equation and got -8-(-12)/1-(-1) which the answer turns out to be 2.
3) similar to question 2. The two points(2,-6) and (-4,-3) are given to you. so I plugged them in again and got -3-(-6)/-4-2 which the answer turns out to be 3/-6 into 1/-3.
4) Same with question 1 find two points of the graph. I chose (0,3) and (1,1) (again might not be accurate it's kind of blurry) I plugged them into the equation again and got 1-3/1-0 which equals -2.
Just always remember y2-y1/x2-x1=m is the equation for slope.
(m is the variable for slope)

The amount of sales tax is $1.90. Since sales tax is found by multiplying the tax rate (in decimal form) times the original cost, we have this equation:
Sales tax = rate * original cost.
We know that sales tax is $1.90 and the original cost is $38.
Plug these numbers into the equation:
1.90 = r * 38
Solve for r by dividing both sides by 38:
r = 0.05
This is in decimal form, so convert it to percent form by moving the decimal 2 places to the right.
Sales Tax rate = 5%
