ok, i will help you.
For the first equation, we have points
(-1, -4)
and
(1, -1)
we also know the y-intercept is
(0, -2)
we can make systems of equations to solve for the equation of this exponiental function
y=ab^x
-1=ab
-2=a*1
a=-2
-1=-2(b)
b=1/2
The exponiental fufnction here is y=(-2)(1/2)^x
2nd equation
(0, 6)
(1, 12)
12=ab
6=a*b^0=6
a=6
12=6(b)
b=2
2nd equation is
y=6(2)^x
Answer:
Ashton read 62 pages over the three days
Step-by-step explanation:
Given;
Ashton read 12 pages on Friday
He read 3 times as many pages on Saturday = 3 x 12 pages = 36 pages
He read 14 more pages on Sunday
The total number of pages read Ashton over the three days can be calculated as follows;
Total pages read by Ashton = 12 pages + 36 pages + 14 pages
Total pages read by Ashton = 62 pages
Therefore, Ashton read 62 pages over the three days
Answer:
The amount Tobie invests in a bank, P = $25
The annual compound interest rate, i = 4%
a. The principal is amount invested in the bank, P = $25
The annual interest rate, i = 4%
b. The function that represents Tobie's account balance, <em>A</em>, after <em>t</em> years is given as follows;
Where;
A(t) = The amount in the account after <em>t</em> years
P = The principal amount
i = The annual compound interest rate
t = The number of years
c. The values to place in the table are found as follows;
At t = 0, 
= 25
At t = 10, 
= 37
The given table is presented as follows;
Step-by-step explanation:
Answer:its the second fourth and fifth
Step-by-step explanation: just did it on edge
Answer:
Height=28
Step-by-step explanation:
You have to work backwards using the formula for a triangle, A=1/2bh
Plug your values in, 126=1/2 9 h
126=4.5 h
126 divided by 4.5 is 28
