712/8=?
First found out what 71/8 is. 71/8 is 8 and 7/8. This tells that there is 7 left so now you add 7 to two which gives you 72. Then you divide 72/8=9 and combine 8 and 9 which gives you 89. So 712/8=89
Answer:
2, 4 ,6 8
Step-by-step explanation:
Given condition y = 2x
When x = 1 , y = 2 *1 = 2
When x = 2 , y = 2 * 2= 4
when x = 3 , y = 2* 3 = 6
When x = 4 , y = 2 * 4 = 8
Hope it will help :)
0.17.
Look at the numbers they have the same. They both start with 0.01...but the next number in the first one is 7, which is greater than 6.
Answer:
C. It means to input a -2 into the function to find the output.
Step-by-step explanation:
f(x) means to the function of x. The question is asking you to input -2 for x and find the answer.
Answer:
For x(θ) = 3cosθ + 2
y² = [9x²/(x - 2)²] - x²
For x(θ) = 3cosθ + 2
x² = [4y²/(y - 1)²] - y²
Step-by-step explanation:
Given the following equivalence:
x² + y² = r²
r = √(x² + y²)
x = rcosθ
cosθ = x/r
y = rsinθ
sinθ = y/r
Applying these to the given equations,
x(θ) = 3cosθ + 2
x = 3(x/r) + 2
xr = 3x + 2r
(x - 2)r = 3x
r = 3x/(x - 2)
Square both sides
r² = 9x²/(x - 2)²
(x - 2)²r² = 9x²
(x - 2)²(x² + y²) = 9x²
(x² + y²) = 9x²/(x - 2)²
y² = [9x²/(x - 2)²] - x²
y(θ) = 2sinθ - 1
y = 2y/r - 1
yr = 2y - r
(y - 1)r = 2y
r = 2y/(y - 1)
Square both sides
r² = 4y²/(y - 1)²
x² + y² = 4y²/(y - 1)²
x² = [4y²/(y - 1)²] - y²
