Answer: =3 x 2 − 12x −15

Step-by-step explanation:

=(3x + 3)(x+−5)

=(3x)(x) + (3x)(−5)+(3)(x)+(3)(−5)

=3x2 − 15x+ 3x − 15

Therefor, the answer is = 3x 2 − 12x − 15

Complete the addition. 7/15+1/3+3/5 Please show work.And explain all reasoning.

stellarik [79]

$\frac{7}{15} + \frac{1}{3} + \frac{3}{5} = \frac{7}{15} + \frac{5}{15} + \frac{9}{15} = \frac{21}{15} = \frac{7}{5} = 1.4$

What is m,y-intercept and the y

amid [387]

Answer: The slope is 500 and the y intercept is 0.

Step-by-step explanation:

To find the slope we need to find the rise and divide it by the run. The y intercept will be when x is equal to 0. And when x is 0 y is also zero because it cuts through the origin meaning that the y-intercept is 0.

The line rises up by 1000 and run by 2 to the right.

Slope : 1000/2 = 500

The slope is 500.

Answer:

Calculate the Macaulay duration of Annuity B at the time of purchase is 1.369.

Step-by-step explanation:

First, we use 0.93 to calculate the v which equals 1/(1+i).

$\frac{0+1*v+2v^{2} }{1+v+v^{2} }$ = 0.93

After rearranging the equation, we get 1.07 $v^{2}$ + 0.07v - 0.93=0

So, v=0.9

Mac D: $\frac{0+1*v+2*v^{2}+ 3*v^{2} }{1+v+v^{2}+ v^{3} }$

After substituting the value of v, we get Mac D = 1.369.
