Answer:
A
Step-by-step explanation:
Use the formula for continuous compound interest:
where p is the principal, r is the interest rate, and t is the time
We know that 10,000 is the principal, the interest rate is 7%, and the time is 8 years, so we can substitute these values in. First, convert 7% to a decimal by dividing by 100
7/100=0.07
Multiply the numbers in the exponent
Multiply
a=17506.725003
Rounded to the nearest cent/hundreth
a=17506.72
So, choice A is correct

Answer:
y=-3x+5
Step-by-step explanation:
concepts: y=mx+b is slope intercept equation formula
m=slope
b= y intercept
Therefore we need to find the slope and y intercept
first find slope
m=
let y2 be 2
let y1 be -4
let x2 be 1
let x1 be 3
6/-2 = -3
m=-3
slope is -3
y= -3x+ b
we need find y intercept now
just plug in (1,2) into that equation
2=-3(1)+b
b=5
y=-3x+5
