Answer:

\frac{3\±\sqrt{3}}{3}

Step-by-step explanation:

Whe have the function 3x^2-6x+2=0

To solve this equation we must factor.

To factor, we need to find the points where the function is equal to zero. So we use the quadratic formula

\frac{-b\±\sqrt{b^2-4ac}}{2a}

Where:

a = 3

b = -6

c = 2

Then

\frac{-(-6) + \sqrt{(-6)^2-4(3)(2)}}{2(3)} = \frac{3+\sqrt{3}}{3}\\\\and\\\\\frac{-(-6) - \sqrt{(-6)^2-4(3)(2)}}{2(3)}= \frac{3-\sqrt{3}}{3}

finally the correct answer is  \frac{3\±\sqrt{3}}{3}

Answer:

Step-by-step explanation:

the formula for a cylinder  is πr^2 x H

if it equals 10 to find the others you just need to do algebra

\pi r^{2} *h = 10

h =\frac{10}{\pi r^{2} }

r =\sqrt{\frac{\frac{10}{h} }{\pi }  }

WHAT IS THE STEPS FOR 13+[9x(3x2)-12]x4
kolbaska11 [484]

Answer:

181

Step-by-step explanation:

Assuming that the 'x's' all symbolize multiplication, follow these steps.

First, begin with the innermost set of parenthesis: 3x2

This will give you the answer of six, this will now give you the new equation of:

13+[9x(6)-12]x4

Following the rules of PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction), it is inferable that you must multiply before subtracting the twelve.

Perform this step: 9x6 to get the answer of 54.

13+[54-12]x4

Now, as there are still brackets, perform the bracketed information:

54 - 12 = 42

This now gives you: 13+[42]x4

Yet again, following the rules of PEMDAS, you multiply 42x4 then add the result of that to 13.

42x4 = 168

168 + 13 = 181

Therefore, this expression provides the answer of 181.

Hope this helps!

Tan 25.5 = h/x

Tan 20.5 = h / x+1

x tan 25.5 = (x+1) tan 20.5

x 0.476975532 = (x+1) 0.373884679

0.476975532x = 0.373884679x + 0.373884679

Deduct both sides by .373884679

0.103090853x = 0.373884679

x = 3.6267 is the first person.

Add one to get for the second person

X = 4.6267
