We make the composition of both functions:
f (x) = x ^ 2-1
g (x) = 2x-3
Then:
f (g (x)) = (2x-3) ^ 2-1
Rewriting:
f (g (x)) = 4x ^ 2-12x + 8
The domain of this function is all real numbers.
Equivalently
x: (-inf, inf)
answer:
x: (-inf, inf)
option 1.

If $300 is invested at a rate of 6% per year and is compounded quarterly, how much will the investment be worth in 12 years?

MAXImum [283]

Answer:

$613.04

Step-by-step explanation:

<em>Compound Interest Formula:</em>

$A = P(1+\frac{r}{n})^{nt}$

n = number of compounds

t = time

r = interest rate

P = principle amount (original amount)

A = final amount

Since it's compounded quarterly, that means there will be 4 compounds per year, so n=4. The interest rate has to be converted to the decimal value, and this is done by simply dividing it by 100 to get r=0.06.

Plug Values into equation:

$A = 300(1+\frac{0.06}{4})^{12*4}$

Simplify inside parenthesis

$A = 300(1.015)^{48}$

Calculate exponent

$A \approx 300(2.043478)$

Multiply values

$A \approx 613.04348$

Round

$A = 613.04$

Help please if i get it wrong i have to start over :(

Ksenya-84 [330]

Answer:

18 square units

Step-by-step explanation:

To find the area of a rectangle, we just need the length and height.

3 vertices of a rectangle are given, which is enough here to figure out the length (x-axis distance) and the height (y-axis distance).

From (0,0) origin to (3,0) would be 3 - 0 = 3 units in the x-axis. That is length:

Length = 3 units

Now, a point is given (0,6), that is in the y-axis. This is from origin. So, the height is:

6 - 0 = 6 units

Height = 6

Now, the area would be:

Area = Length * Height

Area = 3 * 6

Area = 18 square units

Inga [223]

Answer:

1. New balance on July 1=1,484.962

2. New finance charge=97.1362

Step-by-step explanation:

The initial unpaid balance=1753.05 by June

Amy paid 365.39 on June

The unpaid balance after paying 365.39=Initial unpaid balance-amount paid on June

where;

Initial unpaid balance=1753.05

Amount paid on June=365.39

replacing;

The unpaid balance after paying 365.39=(1753.05-365.39)

The unpaid balance after paying 365.39 =1,387.66

The interest will be charged on the unpaid balance of 1,387.66

Interest=Principal×rate×time

Principal=1,387.66

Rate=7% per month

Time(in months)=Early June to early July=1 month

replacing;

Interest=1,387.66×(7/100)×1=97.1362

New balance on July 1=Unpaid balance after paying+Interest

where;

Unpaid balance after paying=1,387.66

Interest=97.1362

replacing;

New balance on July 1=(1,387.66+97.1362)=1,484.962

New balance on July 1=1,484.962

New finance charge=97.1362
