(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
Answer:34p+16g=208
47p+16g=208
Step-by-step explanation:
Let p=the price of each pound of peaches.
Let g=the price of each pound of grapes.
Each pound of peaches sells for $p, so 34 pounds of peaches will bring in 34p dollars. Each pound of grapes will bring in 45g dollars. Therefore, the total amount 34p+45g=192.25
Likewise, if 47 pounds of peaches and 16 pounds of grapes brought in $208 then
47p+16g=208
34p+45g=192.25
47+16g=208
Answer:
x = 4
Step-by-step explanation:
(5x2 - 2x + 1) = (x - 1)
Simplify by multiplying 5 and 2.
(10 - 2x + 1) = (x - 1)
Combine like terms. Remove parentheses.
11 - 2x = x - 1
Cancel out - 2x to get the variable on one side.
- 2x + 2x = 0 x + 2x = 3x
11 = 3x - 1
Do the same with the 1.
12 = 3x
Divide.
x = 4
I would definitely use a calculator for this one. Multiply each set of numbers to get an answer for each, then subtract the two I believe. I got 6288547912.
