Solve by using the quadratic formula: x^2 - 6x + 7 = 0 Please enter any square root values using "sqrt" or the decimal answer ro

olga nikolaevna [1]

Given parameters:

Quadratic expression:

x² - 6x + 7 = 0

Solve using quadratic formula;

x = $\frac{-b +/- \sqrt{b^{2 } - 4ac} }{2a}$

From the equation;

a = 1, b = -6 and c = 7

Input the parameters and solve;

x = $\frac{-(-6) +/- \sqrt{-6^{2 } + 4 x 1 x 7 } }{2 x 1}$

x = $\frac{6 +/- \sqrt{36} +28 }{2}$

x = $\frac{6 +/- \sqrt{64} }{2}$

x = $\frac{6 + 8}{2 }$ or $\frac{6-8}{2}$

x = 7 or -1

Find the volume of a cylinder with base radius of 3 and height of 2

Lunna [17]

Answer:

Volume equals 56.6 when rounded to the nearest tenth

Step-by-step explanation:

YOU NEED A CALCULATOR TO SOLVE THIS!

To find the volume of a cylinder you need the formula $V = \pi r^{2}h$

Now that you have the formula you plug in the radius and the height

$V = \pi (3^{2}) (2)$

Then solve

$V = \pi (9)(2)$

$V = 18\pi$

$V = 56.548667764616278$

Help please im pretty sure this is called angle sum theory but I could be wrong

DENIUS [597]

y = 25

Step-by-step explanation:

=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}

=> 115 = y + 90 

=> 115-90 =y

=> 115 = y + 90

=> 115-90 =y

=> y = 25
