Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Answer:
The value of r will be 0.043
Step-by-step explanation:
Firstly, we need to write the exponential decay formula
the general form of the formula is;
A = P(1-r)^t
where A is the price after a certain year t
P is the initial value
r is the decay rate
t is the time
From the question, we have that;
r = 4.3%
4.3% in decimal will be 4.3/100 = 0.043
The enrollment at a nearby college was 28,000 in 2010. It is decreasing at a rate of 1.1% each
year. What will the enrollment be in 2030
Answer:
22443
Step-by-step explanation:
formula: ab^x
a= starting amount b=exponential decrease x= amount of years
r= rate b= 1-r
a= 28000 b=1-0.011= 0.989 x= 2030-2010= 20 (years)
r= 1.1%= 0.011
Plug into formula:
ab^x
28000(0.989 )^20
= 22443.152645
= 22443

=$28.62jim invested in a savings bond for 6 years and was paid simple interest at an annual rate of 3%. the total interest that he earned was $540. how much did he invest?
Answer:
the principal or invested amount is $457.63
Step-by-step explanation:
The computation of the invest amount is given below:
As we know that
Principal = AMount ÷ (1 + rate × time)
= $540 ÷ (1 + 0.03 × 6)
= $540 ÷ 1.18
= $457.63
Hence, the principal or invested amount is $457.63
Basically we have applied the above formula so that the same would be calculated
how do you find the scale factor in enlargement
Answer/Step-by-step explanation:
Scale factor is the ratio of the corresponding side lengths of two similar figures or shapes.
For an enlargement, divide the length of the new figure over the length of the original figure.
The scale factor of an enlargement should give you a whole number or mixed fraction.
For example, if the length an original figure is 2, and the length when enlarged is 6, the scale factor = 6/2 = 3

Answer:
v = 120
Step-by-step explanation:
The right angle is egual to 180-39-v, so it is: v-141
U now that the sum of the internal angles of a triangle is 180°.
180 = (v-48)+(v)+(v-141)
180 = 3v - 180
3v = 360
v = 360/3
v = 120
Answer:
89 = v

not completely sure how i got it

The amount of money in a bank account increased by 18.5% over the last year. If the amount of money at the beginning of the year is represented by n, which expression represents the amount of money in the bank account after the increase? Select all that apply.
A
n + 0.185n
B
n + 18.5n
C
1.185n
D

E
18.5n
F
19.5n
Answer:
A)n+0.185n C) 1.185n
Step-by-step explanation:
the formula for simple interest is [tex]I=P(1+rt)[/tex]
if the interest rate is 18.5% and the time is 1 year, it would look like:
[tex]P(1+0.185(1))[/tex] or [tex]P(1.185)[/tex]

9000 dollars Is places in an account with an annual interest rate of 7.75%. How much will be in the account after 18 years, to the nearest cent?
Answer: $21555
Step-by-step explanation:
First, we need to know the interest generated on the money saved. This will be:
= Principal × Rate × Time
= $9000 × 7.75% × 18
= $12555
The amount in the account after 18 years will then be:
= Principal + Interest
= $9000 + $12555
= $21555
