Mr. Peterson sold a parcel of land and decided to share half of the amount he got among his three children Jane, Peter and martha in the ratio 4:5:7 respectively and according to their ages. the youngest child, who is 12 years old, received a$2000. how much money did peter and martha received?

$6,000

Step-by-step explanation:

If is the amount of money a child receives, and is the total amount being divided among the children, then

Jane's share:  

Peter's share:  

Martha's share:  

We know Jane got $2000, so we can use that to solve for :

Plug this x value in to find how much Peter and Martha received:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
