In which A(0) is the initial value and r is the growth rate, as a decimal.
A student get a grant of $10000 a year assuming her grant is increased by 7% each year
This means that 
So



What will her grant be in four years time?
This is A(4). So


Her grant in four years time will be of $13108.
We know the number of all ways to take one marble and then take another marble is: 10x9=90
The first time, Jamie wants to pick a white and the ways is: 3
Now we have only 9 marble with 2 white and 7 blues, she has 7 ways to take a blue . So, she has 3x7=21 ways to take what she wants.
And we do the division 21:90=7/30. and that is the answer

Answer:
Vertex is (4,1)
Step-by-step explanation:
x=-b/2a so you need to first divide the b (second term) by the a (first term) so you should get 1 as your new a and -8 as your new b. Negative (-8) is just 8 then divide that by 2(1) which is just 2 which equals 4. That is your x. To find your y, you plug your x back into the original equation and then solve it. Hope this helps!
