Find the amount if $500 was invested at 8% which compounded quarterly after a period of 2½ years. (please show workings)​

for the two given fractions 3/4 and 1/6 we have:

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

Then we conclude that for the two given fractions 3/4 and 1/6 we have:

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

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

Then, 520 people required to accommodate = 1/65 × 520

                                                                      = 8 Halls.

The average rate of change of the function from x == -4 to x = 3 is calculated as: -26.

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.

Answer: $466.

Step-by-step explanation:

Add all the numbers in the graph together, you get 194.

Now, subtract 194 from 660, you get 466. That's how much profit the company makes.

The required generated profit on iPhone 4s is given as $466.2.

The cost price is defined as the is the price of producing something while the selling price is the amount that the buyer pays.

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
Profit = $466.2

Thus, the required generated profit on iPhone 4s is given as $466.2.

The baseball coach bought each pizza at an approximate cost of $ 10 or an exact cost of $ 10.75.

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.

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

3) (2²)³ = 2^6      => using power of a power

Answer:

p=2

Step-by-step explanation:

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, ∞).

Answer:(0,4)

Step-by-step explanation:

If Benjamin has 25 papayas, given the ratio of papayas to pears as 50:94, he has 47 pears.

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 (:).

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).

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.

7 in 7.8 is 100 times greater than 7 in 23.97.

As the name suggests place value is where the digit is being placed in decimal number system.

We can multiply both these numbers by 100 in that way we'll get rid of the decimal and it doesn't effect our answer.

Now 7.8 and 23.97 multiplied by 100 becomes 780 and 2397.

We can observe that 7 in 780 is in hundreds place and 7 in 2397 is in ones place.

∴ If we divide (100/1) = 100.
