Answer:

A-2, B-5, C-1, D-6, E-3, F-4

Step-by-step explanation:

The A would be the function x^3, so it would be the volume of a cube which is #2

B is probably the temperature graph, because it is warmest in the middle of the day and cooler at both ends, so that is #5

C is probably the age of an oak tree because it starts at 0, and grows linearly. #1

E is #3 because it is decreasing and so is the fuel in the tank.

F is the area of a triangle one, because that would be a quadratic function (half of a parabola)#4

D is the car wash, it doesn't start at 0 because the x-axis is the time of day. #6

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 $A=42000(1.04)^n$

Multiply and divide from left to right
