Answer:
First one: C. Second One:C.
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?
a) $13,935.76
b) $12,874.57
c) $13,792.99
To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.
A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.
a) $613.98
b) $546.78
c) $592.17
To solve this this is also an exponential function. The price started at $450 and the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.
Answer:
62.41
Step-by-step explanation:
19 7/8= 19.875
C= pie x d
C= 3.14 x 19.875
C= 62.4075
C= 62.41 (if you want 2 decimal places)
Slope = (-12 - 43)/(4 +7) = -55/11 = -5
y = mx + b
43 = -5(-7) + b
43=35+b
b = 8
equation
y = -5x + 8
ANSWER
See attachment.
EXPLANATION
The given inequality is
Divide both sides by 3 to get,
Because the inequality involves '<' we use a hollow circle at 2⅔.
The solution set of this inequality is shown on the number line in the attachment.
3 times 8 is 24 and adding 7 is 31 so 31/1 divided by 19/1
U must flip the 19/1 to 1/19 and make it multiplication sign
31/1 times 1/19 is 31/19 or 1.63157
