F(-2) means the value of x is -2

Replace x with -2 and solve:

3^-2 = 1/9

5 x 1/9 = 5/9

Answer:

5/9

Step-by-step explanation:

f(x) = 5 * 3^x

Let x = -2

f(-2) = 5 * 3^-2

We know a^-b = 1/a^b

     = 5 * 1/3^2

    = 5/9

miv72 [106K]

Answer:

4/5x+2/5 = y

Step-by-step explanation:

(-3, -2) & (2,2) - given points

1. Find Slope

2-(-2) / 2-(-3) = 4/5

m=4/5

2. plug in points to find b

4/5(x)+b=y : mx+b=y (slope intercept form)

4/5(2)+b=2

8/5+b=2

2 - 8/5 = b

10/5 - 8/5 = b

b=2/5

Therefore: 4/5x + 2/5 = y

I need this TONIGHT!!! Three years ago, Jolene bought $750 worth of stock in a software company. Since then the value of her pur
Paul [167]

Answer:

A\approx\$880.68

Step-by-step explanation:

So, we know that Jolene bought an initial $750.

We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.

So, we can use the compound interest formula, which is:

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

Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.

So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:

A=750(1+0.055)^t

Add:

A=750(1.055)^t

Since the stock was bought 3 years ago, the value <em>now</em> is t=3. So, substitute 3 for t and evaluate:

A=750(1.055)^3

Evaluate. Use a calculator:

A\approx\$880.68

And we're done!

What is the value of g^-1(9)
mars1129 [50]
Hi there!

• g(x) = 6x - 3

Then,
if g(x) = y :-

y = 6x - 3

⇒6x = y + 3

⇒x = \dfrac{\text{y} + 3}{6}

According to th' question :-

g⁻¹(x) = \dfrac{\text{x} + 3}{6}

g⁻¹(9) = \dfrac{9 + 3}{6}

g⁻¹(9) = \dfrac{12}{6}

g⁻¹(9) = 2

Hence,
The required answer is g⁻¹(9) = 2

~ Hope it helps!
