Answer:
0
Step-by-step explanation:
slope= gradient
Gradient= Y2 - Y1 / X2 - X1
= -15-(-15)/-7-19 , = -15+15/-7-19
= 0
Answer:
The amount of interest earned after a year is $32.25
Step-by-step explanation:
In this question, we are asked to calculate the amount of interest generated by depositing a sum into an account.
To calculate the interest earned, we use the simple interest formula.
Mathematically;
I = PRT/100
where I is the interest earned
R is the rate which is 6.25% according to the question
T is the time taken which is 1 year
P is the amount of money deposited also know. as the principal which is $516
Plugging these values we have
I = (516 * 6.25 * 1)/100 = $32.25
Answer:
B - P=11.8(1.02)^t
Step-by-step explanation:
An exponential function is defined as:
.
Recall, a is the starting value, b is the rate, and x is the input (often time).
We will substitute a=11.8 million, b=1.02, and x=t for years. Notice b=1.02 and not 0.02. Because the population is increasing, we multiply by 1+r to add the growth onto the current population.
We write: 
where y is population in millions.
3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.
