(x + 8)^2 + (y - 15)^2 = 17^2

Equation of a circle
Midpoint at (a,b)

(x - a)^2 + (y - b)^2 = r^2

You know what the circle’s center is so you can substitute those values in

(x + 8)^2 + (y - 15)^2 = r^2

But you don’t know what the radius is. To find the radius, we know that the circle passes through the origin (0,0) so you just use the distance formula to figure out the radius length.

Distance formula:

Square root of (x1 - x2)^2 + (y1 - y2)^2

So...

Square root of (-8 - 0)^2 + (15 - 0)^2
Square root of 64 + 225
Square root of 289
r=17

So you substitute 17 into the equation of a circle formula and the result is:

(x + 8)^2 + (y - 15)^2 = 17^2

~~hope this helps~~

Continuous functions f, g are known to have the properties z 4 1 f(x) dx = 19, z 4 1 g(x) dx = 12 respectively. use these to fin
Ahat [919]

I guess this reads

\displaystyle\int_1^4f(x)\,\mathrm dx=19

\displaystyle\int_1^4g(x)\,\mathrm dx=12

You want to compute

I=\displaystyle\int_1^4(8f(x)-g(x)+7)\,\mathrm dx

By linearity of the definite integral,

I=\displaystyle8\int_1^4f(x)\,\mathrm dx-\int_1^4g(x)\,\mathrm dx+7\int\mathrm dx

I=8\cdot19-12+7(4-1)=\boxed{161}

Jim washes 2/3 of his car with 1/2 a bottle of soap. What fraction of the soap will he use to clean his entire car?​
Sunny_sXe [5.5K]

Answer:

if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash

so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap

the entire car needs <u><em>3/4 of a bottle of soap</em></u>
