FACTS TO KNOW BEFORE SOLVING :-

Circumference of a circle with radius 'r' is = [tex]2\pi r[/tex]

⇒ Circumference of half-circle with radius 'r' = [tex]\frac{2\pi r}{2} = \pi r[/tex]

SOLUTION :-

Radius = [tex]\frac{Diameter}{2} = \frac{8}{2} = 4[/tex]

Answer:

A = $560.00

Step-by-step explanation:

I = A - P = $60.00

Formula:

[tex]A = P(1 + rt)[/tex]

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:

A = 500(1 + (0.06 × 2)) = 560

A = $560.00

The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

Answer:

P = 131 degrees

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180 degrees

The exterior angles shown form a straight line with the corresponding interior angle

So the two interior angles can be calculated

The sum of two angles on a straight line is 180 degrees

By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180

Thus;

P + (180-162) + (180-149) = 180

P + 18 + 31 = 180

P = 180-31-18

P = 131

Answer:

- 1 ≤ x ≤ 2

Step-by-step explanation:

Given

- 3 ≤ 5x + 2 ≤ 12 ( subtract 2 from each interval )

- 5 ≤ 5x ≤ 10 ( divide each interval by 5 )

- 1 ≤ x ≤ 2

Answer:

expanded:

y = sin(4x)*sin(4x)*cos(3x)

need to use the product rule and chain rule

look at individual derivatives, use chain rule

d/dx sin(4x) = 4cos(4x)

d/dx cos(3x) = -3sin(3x)

put it together using product rule

dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)

simplify

dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)

answer is A.

The total cost of the tent is 409.86

------------------------------------------------------

explanation:

230×0.65=149.50

230+149.50=379.50×.08=30.36

379.50+30.36=409.86

(Hope this helps :) )

============================================================

Explanation:

65% = 65/100 = 0.65

65% of 230 = 0.65*230 = 149.50

When applying markup, the store increases the cost by $149.50 to get the retail price of 230+149.50 = 379.50, which is the price the customer sees. This is the price before tax.

As a shortcut, we can say 1.65*230 = 379.50 because 1.65 = 1 + 0.65 = 100% + 65%. So 1.65 effectively means "increase the value by 65%"

Similarly, the multiplier 1.08 means "increase by 8%". The cost after tax would be 1.08*379.50 = 409.86 which is the answer

----------

As an even quicker shortcut, we can do both increases at once to say:

1.65*1.08*230 = 409.86

The order of multiplication doesn't matter. The two multipliers 1.65 and 1.08 can be combined into 1.65*1.08 = 1.782 which represents a 78.2% increase overall. After the mark up and tax are considered, the jump from $230 to $409.86 is 78.2%

We can apply the percent change formula to confirm this

A = old value = 230

B = new value = 409.86

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (409.86-230)/230 ] * 100%

C = 0.782 * 100%

C = 78.2%

So it might be tempting to say 65% + 8% = 73%, but as you can see above, that calculation is not true.

Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.

Total Revenue = Number of Units Sold X Cost Per Unit

According to the question

a> The company wants to reduce total expenses to $1,300.

Then expenses would i cut is from

Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.

b>After the decision the impact will be on profit is

It will increase our profit by $1,300 as

Profit = Sales - Expenses  

c>if the company increases prices 20%

i.e

If price will be increases then revenue will also increase by 20%

As  Total Revenue = Number of Units Sold X Cost Per Unit

Therefore ,

Total Revenue = 356500 * 1.2

                         = 427800

d> If the cost of supplies (inputs) decreases,

The impact on profit is it will increase

as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .

e> If the supply of a product goes down,

It will lower the revenue or sales also

as Total Revenue = Number of Units Sold X Cost Per Unit  

But if supply of a product goes down and price per unit  increase it will maintain the sales or revenue  .

Hence, The answers of questions given are explained .

Answer:

No

Step-by-step explanation:

Linear values will increase by a common difference. For example, a linear function might increase by 6 every time or -4. However, this table does not; each time it increases by a different factor. Since there is no common difference and it does not follow an arithmetic function it is not linear.

Answer:

Step-by-step explanation:

Not linear.

If the inputs were 1, 2, 3, 4 and we wanted a linear function, one such function would be 1, 2, 3, 4 or 10, 20, 30, 40, and so on.

The given table shows that y increases faster and faster as x increases.

From x = 1 to x = 2, y increases from 1 to 2 (an increase of 1).

From x = 2 to x = 3, y increases from 2 to 6 (an increase of 4).

From x = 3 to x = 4, y increases from 6 to 24 (an increase of 18)

No, the table does not represent a linear function.

Step-by-step explanation:

Dave + 6 friends = 7 friends in total

84 ÷ 7 = 12

Each friend paid $12

Each of them paid $12 for the Meal.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Dave and 6 friends went to dinner.

Total amount of meal= $84

So, each of them paid

= 84/ 7

= 12

Thus, each of them paid $12.
