Answer: 1 unit

Step-by-step explanation:

The formula for calculating the distance between two points is given as :

D = $\sqrt{(x_{2}-x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}}$

$x_{1}$ = - 7

$y_{1}$ = 7

$y_{2}$ = 8

substituting into the formula , we have

$\sqrt{(-7-(-7))^{2}+ (8-7)^{2}}$

D = $\sqrt{1}$

D = 1 unit

Find the x-coordinates where f '(x) = 0 for f(x) = 2x + sin(2x) in the interval [0, 2π]. so far I found f'(x)=2cos(2x)+2 cos(2x)

From there, you simply need algebra and a calculator that works in radians.

Take the inverse cos of both sides to get 2x = arccos(-1)

Then divide both sides by 2 to get x = arccos(-1) / 2

Put that into a calculator and you get π/2. But because your bounds are 0 to 2π, you have to add π your solution to get the solution on the other side of the unit circle, which would be (3π/2).

Now that you have the x value, put (π/2) and (3π/2) into f(x) to get the y coordinate.

f(π/2) = 2(π/2) + sin(2(π/2) = π, which means this solution is just (π/2, π)
f(3π/2 = 2(3π/2) + sin(2(3π/2) = 3π, which means this solution is (3π/2, 3π)

In Seattle, the tax on a property assessed at $570,000 is $12,540. If tax rates are proportional in this city, how much would th

marta [7]

12,540 / 570,000 = x / 460,000
cross multiply
570,000x = 5768400000
x = 5768400000 / 570,000
x = 10,120 <=== tax on 460,000
