Answer:
y = 2·2^x
Step-by-step explanation:
When the exponential function is of the form ...
y = a(b^x)
The value of 'a' is the value of y when x=0. The table tells us a = 2.
The value of 'b' is the ratio between values of y when their corresponding x-values differ by 1. The table tells us b = (4/2) = 2.
Then the exponential function describing the table is ...
y = 2(2^x)
Perform the indicated operation. Reduce to lowest terms if possible.

A women buys a coat through the mail for $250 plus 9% sale tax. If another 10% is added onto this total for shipping and handling, what is the total cost of the coat ?
Answer:
Find 9% of 250 by turning 9% into a decimal.
.09 x 250 gives you 22.50
add 22.50 to 250
now you have 272.50
now find 10% of 272.50 by converting 10% into a decimal.
.10 x 272.50 gives you 27.25
Add that to 272.50 and you total cost is

Suppose that the value of a stock varies each day from $12.82 to $33.17 with
a uniform distribution.
Find the third quartile; 75% of all days the stock is below what value?
Answer:
$28.08
Step-by-step explanation:
$33.17 - $12.82 = $20.35
75% of $20.35 = $15.26
$15.26 + $12.82 = $28.08

After training for and running a marathon, an athlete wants to reduce her daily run
by half each day. The marathon is about 26 mi. How many days will it take after the
marathon before she runs less than a mile a day? Show your work.
Answer:
6 days
Step-by-step explanation:
This question becomes much easier when written out per day (shown below). The question tells us that she is reducing her run by half every day, so all we need to is divide the previous day by 2 to get the current day. She starts out with 26 miles so this is our day 1 value.
Day 1 = 26 miles
Day 2 = 13 miles (26÷2=13)
Day 3 = 6.5 miles (13÷2=6.5)
Day 4 = 3.25 miles (6.5÷2=3.25)
Day 5 = 1.625 miles (3.25÷2=1.625)
Day 6 = 0.8125 miles (1.625÷2=0.8125)
We can see that by day 6, her total running amount is less that 1 mile, so the final answer is 6 days.

(−1/5)÷(−4/5)
What is the quotient?
Enter your answer as a simplified fraction in the box.
The quotient from the expression (−1/5) ÷ (−4/5), in the simplified fraction is 1/4.
We have,
To calculate the quotient of the expression (−1/5) ÷ (−4/5), you can follow these steps:
- Invert the second fraction (divisor): (-4/5) becomes (-5/4).
- Multiply the first fraction (dividend) by the inverted second fraction: (-1/5) * (-5/4).
- Simplify the result if possible.
(-1/5) * (-5/4)
= (1 * 5) / (5 * 4)
= 5 / 20
Both the numerator and denominator have a common factor of 5, which can be cancelled out:
5 / 20 = 1 / 4
Thus,
The quotient in the simplified fraction is 1/4.

First four terms
f(n)=n^3-n^2+1
Answer:
The function of this equation is: [tex]F(n)=\frac{1}{4}n^4-\frac{1}{3}n^3+n+C[/tex]
Step-by-step explanation:
Answer:
1, 5, 19, 49
Step-by-step explanation:
To obtain the first 4 terms substitute n = 1, 2, 3, 4 into f(n)
f(1) = 1³ - 1² + 1 = 1 - 1 + 1 = 1
f(2) = 2³ - 2² + 1 = 8 - 4 + 1 = 4 + 1 = 5
f(3) = 3³ - 3² + 1 = 27 - 9 + 1 = 18 + 1 = 19
f(4) = 4³ - 4² + 1 = 64 - 16 + 1 = 48 + 1 = 49
The first 4 terms are 1, 5, 19, 49
