Answer:
Step-by-step explanation:
We have the conversion from polar coordinates to cartesian as
x =rcost and y = rsint where (r,t) are the polar coordinates
Also all trignometric functions are periodic with period = 2pi
Using this we find out

Thus we converted polar to rectangular coordinates.
Reverse would be
from (x,y) to (r,t) as

Answer:
Yes The triangles are similar by SAS Similarity Theorem
Step-by-step explanation:
we know that
<u>Side-Angle-Side Similarity,</u> states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar
In this problem
Angle L is congruent with Angle Z
so
Verify if the included sides are proportional
so

substitute the values

-----> is true
therefore
The triangles are similar by SAS
Estimation: 500×7=3,500
Product: 503×7=3,521
Answer:
C
Step-by-step explanation:
Because 3 * 3/6 or 3* 1/2 equals 1.5 or 1 and 1/2 and that is what is shown on the graph!
Hope this Helps!
A. 6n+3n+10= 9n+10. Jordan is 9n+10 years old.
B. 6n+9n+10= 15n+10. The total age of Prince and Jordan is 15n+10.
C. 6n-9. Kimberly is 6n-9 years old.
D. (6n+9n+10)+6n-9 = 15n+10+6n-9 = 15n+6n+10-9 = 21n+1. The total age of Prince, Jordan and Kimberly is 21n+1
E. 21•(4)+1=84+1=85. The total age of Prince, Jordan and Kimberly is 85 years.
