Harmony earns 42,000 salary in the first year of her career. Each year, she gets a 4% raise. Which expression gives the total am

kiruha [24]

Answer:

$A=42000(1.04)^n$

Step-by-step explanation:

This is a compound interest formula expressed as:

$A=P(1+i)^n$

Where

$n$ is time in years
$i$ is the rate of interest
$A$ is the accumulated amount after n years
$P$ is the initial amount.

#We substitute the given values to determine amount after n years as follows:

$A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n$

Hence, the amount earned after n years of her career is given by $A=42000(1.04)^n$

A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours. A)Express the total distance travel

erik [133]

Answer:

$12.5x-285$ .

Step-by-step explanation:

We are told that a man drove x miles per hour for 3 hours, so he traveled 3x miles in three hours.

We are also told that he drove (2x-60) miles per hour for the next 4.75 hours. So The distance traveled by in next 4.75 hours will be:

$4.75\cdot (2x-60)=9.5x-285$

To find the total distance traveled by man we will add distances traveled by him in first 3 hours and next 4.75 hours.

$\text{The total distance traveled}=3x+9.5x-285$

Upon combining like terms we will get,

$\text{The total distance traveled}=(3+9.5)x-285$

$\text{The total distance traveled}=12.5x-285$

Therefore, the total distance traveled in terms of x will be $12.5x-285$ .
