Which of the following is a solution to 3x^2 = 36?

Answers

Answer 1

Answer:

x = √12

Step-by-step explanation:

Easy:

3x^2 = 36

Cancel out the 3 so it is only x^2; you can do this by dividing each side by 3 which gives you:

x^2 = 12

Square root the entire thing to get rid of the square and you get the answer

x = √12

Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.

Multiply 2x^2 by 4 (A times C)

Find what numbers multiply to give you 8 and add to give you 7.

When you do this, you will notice that there are no numbers that do this. That makes your answer D. NONE OF THESE.

x=1/3

Step-by-step explanation:

Factor out 5^3x

5^3x(1-1/5)=4

Combine the fractions

5^3x(4/5)=4

Multiply both sides by 5/4

5^3x=5

Now we have the same base of 5 so we can set the exponents equal to one another (the exponent of 5 is 1)

What is the present value of an ordinary annuity having semi-annual payments of 8000 for 12 years with an interest rate of 12%compound semi- annually?

Answers

Answer:

PV= $100,402.86

Step-by-step explanation:

To calculate the present value, first, we need to determine the future value using the following formula:

FV= {A*[(1+i)^n-1]}/i

A= semiannual deposit

n=12*2= 24 semesters

i= 0.12/2= 0.06

FV= {8,000*[(1.06^24) - 1]} /  0.06

FV= $406,524.62

Now, the present value:

PV= FV / (1+i)^n

PV= 406,524.62 / 1.06^24

PV= $100,402.86

solve for 65+5x and show work !!!

Answers

Answer:

x = -13

Step-by-step explanation:

65 + 5x = 0

65 = -5x

divide by -5

-13 = x

Answer:

x = 13

Step-by-step explanation:

You have to get x by itself

so you divide 5 by 65

Then X is by itself and your answer is 5/65

Answers

Answer:

z = 100°

x = 40°

Step-by-step explanation:

Triangle CBD is isosceles so there are two 50°

DBC = 50°

That means BDC = 80° because 180(sum of angles in triangle) - 50 - 50 = 80

Z = 100° bc angle of straight line is 180° and 180 - 80 = 100

Now triangle ADB is also isosceles because there are two sides of equal length

So there will be 2*x + 100 = 180

x = 40°
