Answer:
aₙ = 2*n*n - n -1
Step-by-step explanation:
a₁ = 0
a₂ = 5 = 2*2*2 -2-1 = 8-3 = 5
a₃ = 2*3*3 -3-1 = 18-4 =14
a₄ = 2*4*4 - 4-1 = 32-5 =27
......
aₙ = 2*n*n - n -1

Identify the initial amount a and the rate of decay r (as a percent) of the exponential function h (t) = 1250(0.865)'. Evaluate the
function when t 3. Round your answer to the nearest tenth.
Answer:
809.0
Step-by-step explanation:
Given the exponential function h (t) = 1250(0.865)^t
When t = 3
h(3) = 1250(0.865)^3
h(3) = 1250 (0.6472)
h(3) = 809.0
Hence the value to the nearest tenth is 809.0

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters. What is the probability of drawng a quarter, replacing it, and drawing another quarter.
Given:
A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.
To find:
The probability of drawing a quarter, replacing it, and drawing another quarter.
Solution:
A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.
Total number of coins = 8+5+1+7 = 21
Probability of getting a quarter is
[tex]P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}[/tex]
[tex]P(Quarter)=\dfrac{7}{21}[/tex]
[tex]P(Quarter)=\dfrac{1}{3}[/tex]
After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., [tex]P(Quarter)=\dfrac{1}{3}[/tex].
The probability of drawing a quarter, replacing it, and drawing another quarter is
[tex]P=\dfrac{1}{3}\times \dfrac{1}{3}[/tex]
[tex]P=\dfrac{1}{9}[/tex]
Therefore, the required probability is [tex]\dfrac{1}{9}[/tex].

Maria used one bag of flour to bake some bread and muffins. First, she baked two loaves of bread. Then she used the remaining flour to make muffins. If the bag contained 15 cups of flour, how many muffins did Maria make?
recipe - amount of flour needed
bread - 1 1/2 cups per loaf
muffin - 1/3 cup per muffin
rolls - 1/4 cup per roll
a
12 muffins
b
4 muffins
c
36 muffins
d
45 muffins
Answer:
c
Step-by-step explanation:
1 1/2 cups x 2 bread = 12
12 cups x 3 for 1/3 per recipe =36
Answer:
C.
Step-by-step explanation:
2 loaves of bread: 1 1/2 (flour per one loaf) * 2 (amt of loaves) = 3 (total flour used)
15 (total amt of flour) - 3 (flour used to bake bread) = 12 (remaining flour)
12 (remaining flour) / 1/3 (flour per muffin) = 36 (muffins able to be made)
If there are 5,280 feet in a mile and 3,600 seconds in an hour, then a speed of 26 feet per second is closest to which of the following
Answer:
17.72[tex]\frac{miles}{hr}[/tex]
Step-by-step explanation:
If you are trying to take 26 ft/s to being miles per hour this is how you do it.
26 [tex]\frac{ft}{s}[/tex] * [tex]\frac{mile}{5280ft}[/tex] *[tex]\frac{3600s}{hr}[/tex]
so
17.72[tex]\frac{miles}{hr}[/tex]

Someone plz help me show your work!
Answer:
1/6
Step-by-step explanation:
We know that 1/2 are apples and 1/3 are bananas
we also know that
apples+bananas+oranges=1
Which means that
1/2+1/3+oranges=1
Add 1/2 + 1/3 by getting the denominators equal
3/6+2/6=5/6
Which means that 5/6+oranges=1
1-5/6=1/6
1/6
write everything below this
1/2+1/3+oranges=1
1/2+1/3=5/6
5/6+oranges=1
oranges=1-5/6
oranges=1/6

It took 9 gallons of gas for a car to travel 216 miles. What is the rate of the car in miles per gallon of gas? help me quick
Answer:
24 miles per gallon
Step-by-step explanation:
To find the rate of miles per gallon divide the miles (216) by the gallons (9). 216/9 is 24. So the answer is 24 miles per gallon.
*Miles per gallon is underlined because it gives a hint on how to solve this. Miles per (divide) gallon.
Hope it helps!
Answer:
The rate is 24 miles per 1 gallon
Step-by-step explanation:
If 9 gallons = 216 miles, divide both sides by 9
so 1 gallons is 24 miles
The rate should be 24 miles per 1 gallon
Remember: Rate equals distance divided by time

Limone's Lemonade Corp. Has a savings plan for its employees. If an employee makes an initial contribution of $1,000.00, the company pays 8% interest compounded quarterly. What is the value of the account after 5 years?
Answer:
$1485.95
Step-by-step explanation:
The formula to be used is :
FV = PV (1 + r/m)^mn
FV = Future value
PV = Present value
R = interest rate
N = number of years
m = number of compounding
1000x (1 + 0.08/4)^5x4 = $1485.95
