A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year

Andru [333]

Answer:

$y = 18 * 1.15^x$

Step-by-step explanation:

Given

$a = 18$ --- initial

$r =15\%$ -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

$y = ab^x$

Where

$b=1 +r$

Substitute $r =15\%$ in $b=1 +r$

$b = 1 + 15\%$

$b = 1 + 0.15$

$b = 1.15$

Substitute $b = 1.15$ and $a = 18$ in $y = ab^x$

$y = 18 * 1.15^x$

15 POINTS!!!! BRAINLIEST FOR THE FIRST ANSWER!!! Solve 3-x/2≤18

Bumek [7]

Answer:

$x\geq -30$

Step-by-step explanation:

Work to isolate x on one side of the inequality:

$3-\frac{x}{2} \leq 18\\3-18\leq \frac{x}{2} \\-15\leq \frac{x}{2}\\-30 \leq x$

Therefore the answer is all x values larger than or equal to -30

$x\geq -30$

In Exercise, use the properties of logarithms to rewrite the expression as a sum, difference, or multiple of logarithms.

Kamila [148]

Answer:

The simplified expression is:

$\frac{\ln{(x + y)}}{2}$

Step-by-step explanation:

We have those following logarithmic properties:

$\ln{\frac{a}{b}} = \ln{a} - \ln{b}$

$\ln{a*b} = \ln{a} + \ln{b}$

$\ln{a^{n}} = n\ln{a}$

In this problem, we have that:

$\ln{(x + y)^{\frac{1}{2}}$

$\frac{\ln{(x + y)}}{2}$

So the simplified expression is

$\frac{\ln{(x + y)}}{2}$
