If m/8 =57, find m/1.​
Valentin [98]

Answer:

696

Step-by-step explanation:

\frac{m}{8}  = 87

First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).

m=87*8\\m = 696

Because any number divided by 1 would just be itself, 696/1 is just 696.

- Please help this is a Rational Inequality problem
Katyanochek1 [597]

1. The solution for the equation is -16t² + 64t > 0

2. The interval notation for the equation is (0, 4)

Given,

The height of the building = 400 feet

A ball is thrown straight up from the top of the building.

The initial velocity of the ball = 64 feet/second

The height of the object is modeled by, s(t) = -16t² + 64t + 400

1. Solution for the equation:

s(t) > 400

So,

-16t² + 64t + 400 > 400

Add -400 to both sides

ie, -16t² + 64t + 400 - 400 > 400 - 400

We get,

-16t² + 64t > 0

2. Now find the interval notation for the equation:

-16t² + 64t > 0

Here, 64/16 = 4

So,

-16t (t - 4) > 0

Now,

t = 0 and t - 4 = 0  

The interval notation for the equation is (0, 4)

SOLVE USING THE QUADRATIC FORMULA <br><br> 1) y=3x^2-x-6<br><br> 2) y=-5x^2+7x+3
kondor19780726 [428]

1) x=\frac{1+\sqrt{73}}{6}\,\,and\,\,x=\frac{1-\sqrt{73}}{6}

2) x=\frac{-7+\sqrt{109}}{-10}\,\,and\,\,x=\frac{-7-\sqrt{109}}{-10}

Step-by-step explanation:

Solving the equations using quadratic formula.

1) y=3x^2-x-6

The quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

where a =3, b = -1 and c= -6

Putting values:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-1)\pm\sqrt{(-1)^2-4(3)(-6)}}{2(3)}\\x=\frac{1\pm\sqrt{1+72}}{6}\\x=\frac{1\pm\sqrt{73}}{6}\\so, x=\frac{1+\sqrt{73}}{6}\,\,and\,\,x=\frac{1-\sqrt{73}}{6}

2) y=-5x^2+7x+3

The quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

where a =-5, b = 7 and c= 3

Putting values:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(7)\pm\sqrt{(7)^2-4(-5)(3)}}{2(-5)}\\x=\frac{-7\pm\sqrt{49+60}}{-10}\\x=\frac{-7\pm\sqrt{109}}{-10}\\So, x=\frac{-7+\sqrt{109}}{-10}\,\,and\,\,x=\frac{-7-\sqrt{109}}{-10}
