The amount generated by the invested amount of $500 which is compounded quarterly will be $610.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]
Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
If $500 had been invested at an annualized rate of 8%, the money would have after 2.5 years. For the quarterly, the value of n will be 4. Then the amount will be
[tex]\rm A = 500 \left (1 + \dfrac{0.08}{4} \right)^{4 \times 2.5}[/tex]
Simplify the equation, then the amount is given as,
A = 500 (1 + 0.02)¹⁰
A = 500 (1.02)¹⁰
A = 500 x 1.22
A = $610
The amount generated by the invested amount of $500 which is compounded quarterly will be $610.

How can you use the
Product of Powers, Power of a Product, and
Power of a Power Laws to evaluate and write
equivalent numerical expressions with whole-
number exponents?
Answer:
An equivalent numerical expression with whole-
number exponent using these laws can be written as:
1) 2² × 2³ = 2^5 => using product of Powers
2) 2² × 3² = (2×3)² = 6² => using power of a Product
3) (2²)³ = 2^6 => using power of a power
Step-by-step explanation:
First of all, let us understand some terms like;
1) Exponentiation: It is the mathematical process of raising one integer to the power of another. The base is the first integer, while the exponent is the second.
2) Power: A power is a phrase that depicts the same component being multiplied repeatedly.
3) Exponent: The number of times the base is used as a factor is represented by the exponent.
Now, let us understand the 7 Laws of Exponents;
1) a^m × a^n = a^(m+n) => Product With the Same Bases
2) a^m / a^n = a^(m-n) => Quotient with Same Bases
3) (a^m)^n = a^(m×n) => Power Raised to a Power
4) a^n × b^n = (ab)^n => Product to a Power
5) a^n / b^n = (a/b)^n => Quotient to a Power
6) a^0 = 1 => Zero Power
7) a^(-m) = 1/a^m => Negative Exponent Rule
Furthermore, an equivalent numerical expression with whole-
number exponent using these laws can be written as:
1) 2² × 2³ = 2^5 => using product of Powers
2) 2² × 3² = (2×3)² = 6² => using power of a Product

A baseball coach spent $118.25 on 11 pizzas. Estimate ate the cost of each pizza using numbers with one nonzero digit. Then find the exact cost per pizza. Show all work
The baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.
What is are the approximate and exact cost of each pizza bought by a baseball coach?
In this problem we know that a baseball coach spends a total of $ 118.25 on buying 11 pizzas. First, we need to estimate the amount of money spent per each pizza bought, which is found by means of multiplication tables and the supposition of truncation, that is, finding the maximum integer less than or equal to the real total cost.
By direct inspection we find that 10 times the 11 pizzas is equal to $ 110, which is the maximum integer less than or equal to the real total cost. Then, we estimate a cost of $ 10 per each pizza bought. Second, the exact unit cost is found by dividing the total by the number of pizzas:
c = $ 118.25 / 11
c = $ 10.75
In a nutshell, the baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.

Here,
As of the mentioned data,
Cost of making an iPhone = $193.8
The selling price of the iPhone = $660
Profit is meant how much money is generated from the product besides the product cost price.
Profit = selling price - cost price
Profit= 660 - 193.9

Benjamin has papayas and pears in a ratio of 50:94. How many pears does he have if he has 25 papayas? On the double number line below, fill in the given values, then use multiplication or division to find the missing value. delta math
If Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.
What is the ratio?The ratio is the numerical relationship that one variable has when compared with another.
The ratio has the same meaning as proportion.
Ratios are represented in percentages, decimals, fractions, or with the ratio sign (:).
How is the number determined?Another way to calculate it is to examine the ratio against the number of papayas he has.
Benjamin has 25 papayas, which is half of 50 (25/50). This means he has half of the pears, which is 47 (94/2).
Data and Calculations:Papayas = 25
The ratio of papayas to pears = 50:94
For every 50 papayas Benjamin has, he has 94 pears.
The number of pears he has = 47 (25/50 x 94)
Thus, if Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

On which interval(s) is the function f(x) = x^3+3x^2−4x−12 increasing?
The interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).
We have,
x³ + 3x² - 4x - 12
We need to draw a graph to see at which interval the graph is increasing.
The graph is given below.
We see that the graph is increasing from x = -∞ to x = -2.5 and from x = -2.5 it decreases till x = 0.5 and again from x = 0.5 it increases to x = ∞.
So we can write the interval as:
x ∈ (- ∞, - 2.5) and x ∈ (0.5, ∞)
We can write it as one single interval as:
S = (- ∞, - 2.5) ∪ (0.5, ∞)
Thus the interval at which the function x³ + 3x² - 4x - 12 increases is
x ∈ (- ∞, - 2.5) ∪ (0.5, ∞).

8 halls would be required to accommodate 520 people in the hall.
As we know that a hall can accommodate 65 people.
To determine the number of hall required for 520 people,
first we need to find that how many halls would be required for one person,
So, we will divide the 1 by 6 to find :
The number of one person accommodate = 1/65 Hall

Part A: Write an equations for EACH company that represents the total charges for renting a car for a certain number of days. For both questions (one for Hertz and one for Enterprise), define the variable used.
Part B: Use the equations you made in Part A. Which company charges more for renting a car for 6 days? Show your work and justify your answer.
Part C: If Avery decides to rent the car for only 4 days, which company is less expensive? How much money will Avery save? Show your work and explain your reasoning.
The total cost functions are:
total charges for Hertz=32+42x
total charges for Enterprise=24+46x
What does the total rental cost of each company entails?
The total rental cost of each company consists the fixed service charges and the daily charge which can be multiplied by the total of number of days of rental to determine total charges overall.
Hertz:
total charges=32+42x
when x=6 days
total charges=32+(42*6)
total charges=$284
Enterprise:
total charges=24+46x
when x=6 days
total charges=24+(46*6)
total charges=$300
Renting for 4 days:
total charges(Hertz)=32+(42*4)
total charges(Hertz)=$200
total charges(Enterprise)=24+(46*4)

for the two given fractions 3/4 and 1/6 we have:
sum = 11/12product = 1/8quotient = 9/2How to work with fractions?Here we have two fractions, 3/4 and 1/6, and we want to find the sum, product, and quotient between them.
First let's do the sum:
3/4 + 1/6
We just need to find a common denominator, which can be 12, so we can rewrite it as:
9/12 + 2/12 = 11/12
The sum of the two fractions is 11/12
Now the product, it is, we multiply denominator with denominator and numerator with numerator, we will get:
(3/4)*(1/6) = (3*1)/(4*6) = 3/24 = 1/8
The product between the two fractions is equal to 1/8.
Finally, the quotient, this is:
The product between the first numerator and second denominator, and between the first denominator and second numerator, so the quotient becomes:
(3/4)/(1/6) = (3/4)*(6/1) = (3*6)/(4*1) = 18/4 = 9/2

Find the average rate of change of
g(x)=-2x^3+5 from z=-4 to x=3
The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.
How to Determine the Average Rate of Change of a Function?The formula for determining the average rate of change across a given interval of a function is expressed as:
Average rate of change = g(b) - g(a)/b - a.
Given the function, g(x) = -2x³ + 5 to find the average rate of change from x = -4 to x = 3, do the following:
a = -4
g(a) = g(-4) = -2(-4)³ + 5 = -2(-64) + 5 = 128 + 5 = 133
b = 3
g(b) = g(3) = -2(3)³ + 5 = -2(27) + 5 = -54 + 5 = -49
Substitute the values into g(b) - g(a)/b - a:
Average rate of change = (-49 - 133)/(3 - (-4))
Average rate of change = -182/7
Average rate of change = -26
Thus, the average rate of change of the function from x == -4 to x = 3 is calculated as: -26.
