the table represent some points on the graph of an exponential function which function represents the same relationship (see image attached)
Answers
Answer: Is the second
Step-by-step explanation:
I took the result of the tables of values with the calculator and it gave me the result I regret not being able to give you an explanation
The exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]
An exponential function is represented as:
[tex]y = ab^x[/tex]
Where:
a represents the initial valueb represents the rateFrom the table we have the following ordered pair
(x,y) = {(0,18) (1,21.6)}
So, we have:
[tex]y = ab^x[/tex]
[tex]18 = a \times b^0[/tex]
[tex]a= 18[/tex]
Also, we have:
[tex]y = ab^x[/tex]
[tex]21.6 = a \times b^1[/tex]
[tex]21.6 = 18 \times b[/tex]
Divide both sides by 18
[tex]b = 1.2[/tex]
So, we have:
[tex]y =18 \times 1.2^x[/tex]
Rewrite as:
[tex]y =18 (\frac 65)^x[/tex]
Hence, the exponential function that represents the table is [tex]y =18 (\frac 65)^x[/tex]

Given the speeds of each runner below, determine who runs the fastest.
Stephanie runs 12 feet per second.
Liz runs 306 feet in 38 seconds.
Will runs 1 mile in 491 seconds.
Brooke runs 851 feet in 1 minute.
Answers
Answer:
Brooke
Step-by-step explanation:
We can solve this by figuring out how far each person runs a second
Stephanie runs 12 feet a second so nothing needs to be done here
Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet
Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75
Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18
Brooke obviously runs the furthest in one second and therefore she's the fastest runner

Braxton puts $1,275 into a savings account that earns 3% simple interest per year. How much total money will be in his account after 5 years?
A) $191.25
B) $1,466.25
C) $19,125.00
D) $20,400.00
Answers
Answer:
The answer would be B) 1,466.25
Step-by-step explanation:
The formula we'll use for this is the simple interest formula, or:
I= P x r x t
Where:
P is the principal amount, $1275.00.
r is the interest rate, 3% per year, or in decimal form, 3/100=0.03.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1275 × 0.03 × 5 to get that:
The interest is: $191.25
Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),
or 1275.00 + 191.25 = 1466.25.
