How to find the diameter of a circle with the area of 1134.1?
Alex17521 [72]
Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38

HELP!!!!!! please<br> by substitution integrates<br> <img src="https://tex.z-dn.net/?f=%20%5Cint%5C%20Sen%5E%7B3%7DxCosx%20%5C%2
Elza [17]
Hello,

I suppose you means

As (sin(x))'=cos(x)

\int\limits{sin^3(x)*cos(x)x} \, dx
=1/4*sin ^4(x)+C
since
\int\limits{u^3} \, du=u^4/4+C

to solve the system of equations below, Becca isolated x^2 in the firs equation and then substituted it into the second equation
bija089 [108]

The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1

<h3>Equation</h3>

x² + y² = 9

x²/25 - y²/36 = 1

From (1)

x² = 9 - y²

substitute x² = 9 - y² into (2)

x²/25 - y²/36 = 1

(9-y²) / 25 - y²/36 = 1

Therefore, the resulting equation is option C; (9-y²) / 25 - y²/36 = 1

The equation of the line that goes through the point (1,5) and is parallel to the line 3x+5y=2 can be written in the form y=Mx+b
Llana [10]

Answer:

y=-\frac{3}{5}x+\frac{28}{5}

Step-by-step explanation:

step 1

Find the slope of the given line

we have

3x+5y=2

isolate the variable y

5y=-3x+2\\\\y=-\frac{3}{5}x+\frac{2}{5}

The slope of the given line is

m=-\frac{3}{5}

step 2

Find the equation of the line that goes through the point (1,5) and is parallel to the given line

Remember that

If two lines are parallel then their slopes are equal

therefore

we have

m=-\frac{3}{5}

point\ (1,5)

substitute in the equation of a line in slope intercept form

y=mx+b

5=-\frac{3}{5}(1)+b

solve for b

b=5+\frac{3}{5}\\\\b=\frac{28}{5}

substitute

y=-\frac{3}{5}x+\frac{28}{5}
