Answer:
Step-by-step explanation:
The answer is c.
Proportional means a relationship of y = a constant multiplied by x
In this case, the constant is 7.
i.e. y = 7x
So if
x is 3, y is 21
x is 5, y is 35
x is 7, y is 49
and so on...
And there you have it.
2.5x + 4x = 39
6.5x = 39
x = 39 / 6.5
x = 6
Well first you multiply 5 times 3 which is 15 then you add 4 which is 19 and 19 times 3 is 57 57-5 is 52
Polar form: (r,θ)
Using these formulas:
x²+y²=r²
tan(θ)=y/x
We have the point (1,1) in cartesian coordinates. We need to find r and θ to get it in polar form.
r²=1²+1²
r²=2
r=±√2
tan(θ)=1/1
tan(θ)=1
θ=π/4 radians or 45 degrees
Polar coordinates: (√2,π/4)
Those answer choices look strange. Are you sure these are the right answer choices?
