2 answers:

8 0

R=4
theta=pi/2

x= r cos(theta) = 4 cos(pi/2) = 4(0) = 0
y = r sin(theta) = 4 sin(pi/2) = 4(1) = 4

(0,4) is the answer.

Answer:

$\dfrac{x}{4}-\dfrac{7}{12}$

Step-by-step explanation:

The fraction is the equivalent of ...

$\dfrac{1}{12}{(3x-7)$

and the distributive property applies.

$=\dfrac{1}{12}(3x)-\dfrac{1}{12}(7)\\\\=\dfrac{3\cdot x}{3\cdot 4}-\dfrac{7}{12}\\\\=\dfrac{x}{4}-\dfrac{7}{12}$

Solve the system of equations. Show ALL your work. Put your answer in the form of an ordered pair (x, y)

stiv31 [10]

This should be easy because we just have to use substitution method. Substitute the value of x from the second equation into the x of the first equation.
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15 ; y = 5
Substitute this value of y to either the first or second equation.
x = 2(5) = 10
The ordered pair is therefore (10,5).

Solve the following proportion for v. V/13=11/13

NeX [460]

Answer:

V = 11

Step-by-step explanation:

All you have to do here is to multiply both sides of this equation by 13. This will eliminate the fractions. You'll be left with V = 11.
