Two students were asked to find the value of a $1000 item after 3 years. The item was depreciating (losing value) at a rate of 4

Yuki888 [10]

Answer:

Student 2 is incorrect because he didn't use the formula properly

Step-by-step explanation:

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

$C(3)=\$1000\cdot(1-0.4)^3$

$C(3)=\$1000\cdot0.6^3$

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly

On question six find the answer and also explain. On question eight find the answer and also explain. On question nine I already

serious [3.7K]

6. No it is not equilateral because a. All the angles should be congruent (60) and as we can tell, they are not, and b. you should never assume measurements.

8. GF is the longest because the angle for that side (GFH) is smaller than the others, so it means it has a longer side.

Your answer for 9 is wrong. The answer is yes because the largest angle = the largest side.

10. AC because largest angle = largest side

11. Literally the same thing as 9 and 10. Largest angle = largest side
