Answer:

1.) P = 8g + 50

2.) Find the attached file for the graph.

Step-by-step explanation:

Let the profit = P

And g = good sold.

Given that each yo-yo sells for $8.00

The rate or the slope of the equation will be 8

Also, it is given that they must pay a clerk $50.00 a day to sell them. A flat rate of 50 dollars is an intercept of the equation.

Using the general linear equation of

Y = mX + C

The equation for the profit the store will make in a day will be.

P = 8g + 50

Please find the attached file for the graph

The solution for b could really be any answers as long as when that number is divided by 4.3 it is less than 11.3

1 possible answer though could be 11.3

Because when 11.3 is divided by 4.3 it is less then 11.3

Sorry if I'm missing something and the answer is wrong!

One of the angles of a triangle is 8 deg more than 5 times another angle. If the third angle is 4 deg larger than the difference

Mars2501 [29]

Answer:

$16^\circ, 88^\circ, 76^\circ$

Step-by-step explanation:

Given a triangle.

One of the angles is $8^\circ$ more than 5 times of one angle.

Third angle is $4^\circ$ more than the difference of two angles.

To find:

The angles.

Solution:

Let the first angle = $x^\circ$

As per question statement, second angle = 5 $x^\circ$ + $8^\circ$

And third angle = 5 $x^\circ$ + $8^\circ$ - $x^\circ$ + $4^\circ$ = $(4x+12)^\circ$

Using triangle sum property that the sum of all the internal angles of a triangle is always equal to $180^\circ$ .

$x+5x+8+4x+12 = 180\\\Rightarrow 10x+20=180\\\Rightarrow 10x = 160\\\Rightarrow x = 16$

Therefore, the first angle = $x^\circ = 16^\circ$

The second angle = $5x+8 = 5 \times 16 + 8 = 80+8 = 88^\circ$

The third angle = $4x+12 = 4\times 16 + 12 = 76^\circ$

Therefore, the angles are $16^\circ, 88^\circ, 76^\circ$ .

What is the surface area of the square pyramid?<br> (Figure is not drawn to scale.)

Reil [10]

Area of the base = 8^2 = 64

area of 1 traingle = 1/2 * 8 * 5.4 = 21.6

there are 4 triangular sides so their area = 4 * 21.6 = 86.4

Total surface area = 64 + 86.4 = 150.4 cm2

The manager of a company uses the function shown to model the company’s daily profit based on the price of a product in dollars,

just olya [345]

Answer: 1) The minimum price, in dollars, to avoid a loss = 22,

2) the maximum price in dollars , to avoid a loss = 53,

3) The price that results the maximum profit = 37.5 dollars

Step-by-step explanation:

Since the given function that shows the total profit,

$f(x) = (x-22)(53-x)$

Where x is the price of the product.

Since for avoiding the loss,

$f(x) \geq 0$ ,

⇒ $(x-22)(53-x)\geq 0$

If $(x-22)\geq 0 \implies x\geq 22$

If $53 - x \geq 0 \implies 53 \geq x$

Thus, 53 ≥ x ≥ 22,

Therefore, the minimum price to avoid the loss = $ 22

And, the minimum price to avoid the loss = $ 53

$f'(x) =\frac{d}{dx}[(x-22)(53-x)] = (x-22)\frac{d}{dx} (53-x)+(53-x) \frac{d}{dx}(x-22)$

⇒ $f'(x) = - (x-22)+(53-x) = -x+22+53-x =-2x+75$

Now, For maximum or minimum,

$f'(x) = 0$ ,

⇒ $-2x+75 = 0$

⇒ $-2x = -75$

⇒ $x = 37.5$

$f''(x) = \frac{d}{dx}(-2x+75)=-1$

For x = 37.5, f''(x) is negative,

Thus, For the price of $ 37.5 dollars the company has the greatest profit.
