Consider the expressions 4t+t and 1t+4t .

1 answer:

5 0

So the full equation would be

4(3)+3 and 1(3)+4(3)

12+3 and 3+12

15 and 15

So your answer is 15 for both problems

Hope this helped. Have a great day!

Answer:

y=3/4m

Step-by-step explanation:

All proportional relationships have the form y=mx where m is the rate of change from the families donations x to the business donations y. We can find the rate of change m by substituting values we already know. We know when x=$12 then y=$9.

9=m*12

We solve for m by dividing by 12 on both sides.

m=9/12

This simplifies to 3/4 so

m=9/12=3/4.

The equation is y=3/4m

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.
