Step-by-step explanation:
Many calculators can perform polar ⇔ rectangular conversion. Attached is the result from one of them. Of course, you can also program a spreadsheet to do it. (The ATAN2( ) function is useful for finding the correct angle.)
If you want to do these calculations by hand, the conversion is ...
<r, θ> ⇒ <r·cos(θ), r·sin(θ)>
In the attached, the rectangular coordinates are shown as complex numbers. The imaginary component is the y-component of the vector.
Answer:
IF TWO VALUES ARE <u>PROPORTIONAL</u> THEY CAN BE CONNECTED IN TERMS OF k BY MAKING THEM IN A STUCTURE OF AN EQAUTION LIKE GIVEN BELOW. HERE AS THE PROPORTIONAL VALUES ARE<u> RADIUS</u> AND <u>CIRCUMFERENCE </u>WE USE THE GIVEN VALUES AND CREATE EQAUTION LIKE BELOW
r=kC
⇒WE CAN TRASNPOSE THIS TO GET
kC/r=0
⇒C/r=1/k
RECIPROCATE IT TO GET
⇒r/C=k
Maybe this will be correct answer
Answer:
Ray = 19 yrs old
Tom = 25 yrs old
John = 57 yrs old
Explanation:
Let x be the years of Tom
R = x - 6
J = 3R = 3(x - 6)
T = x
R + J + T = 101
x - 6 + 3(x - 6) + x = 101
2x - 6 + 3x - 18 = 101
5x - 24 = 101
5x = 125
x = 125/5 = 25
R = 25 - 6 = 19
J = 3(25 - 6) = 57
T = 25
