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 rate

From 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]

A dinner cost $28.50 which included a 15% tip. How much was the tip?
Explain the answer please

Answers

I think it’s $1.60. Just the dinner was 26.60

Answer:

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

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.

the answer is 1,466.25
