Since area is found by radius, we must decide what should have been used. Take half of 6 and you have 3.

Now squaring 3, using the formula gives us 9. Hoshi squared 6 giving him 36. This is 4 times greater. That's because his value was 2 times greater and when we squared it that made it 2 more times greater, or 4 times greater.

Pi cancels itself and does not affect the outcome.

Find the value of the variable and YZ if Y is between X and Z. XY= 11, YZ=4c, XZ=83
svet-max [94.6K]
So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:

11+4c=83
4c=72
c=18

c=18 and YZ=72

Which two values of x are roots
FrozenT [24]
The answer is C. 

To solve these types of equations you first need to make sure that you equation is equal to 0. In this case all of the numbers are already on the same side so no work needs to be done there. Then we can get a, b and c values for the quadratic equation by looking at the coefficients. 

a = 4 (number attached to x^2)
b = -6 (number attached to x)
c = 1 (number with no variable attached)

Now we can put this into the quadratic equation. 

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

\frac{6 +/- \sqrt{ -6^{2} -4(4)(1)} }{2(4)}

\frac{6 +/- \sqrt{20} }{8}

Based on the information below, choose the correct answers.
lozanna [386]

Since there are 120 payment and the total interest paid was $ 14,644.95. so the average monthly interest can be calculated by:

Average monthly interest = $ 14,644.95 / 120

Average monthly interest = $ 122.04

 

% total interest = ($ 14,644.95) / $ 39,644.95 x 100

% total interest =36.94 %
