O x=0

O x=0 or x = -6

O x= 0 or x = 6

O no solution

**Answer:**

x=0 or x=6

**Step-by-step explanation:**

-4|-2x+6| = -24

|-2x+6| = 6

-2x+6 = 6

-2x = 0

x = 0

-2x+6 = -6

-2x = -12

x = 6

Therefore, x=0 or x=6

Differentiate y = sin^2x - cos^2x

Using the power and chain rules, the derivative of

y = sin²(x) - cos²(x)

is

dy/dx = 2 sin(x) cos(x) - 2 cos(x) (-sin(x))

dy/dx = 2 sin(x) cos(x) + 2 sin(x) cos(x)

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

and using the double angle identity for sine, this is equivalent to

**dy/dx = 2 sin(2x)**

Alternatively, we can first simplify y using the double angle identity for cosine:

cos(2x)= cos²(x) - sin²(x)

so that

y = -cos(2x)

and the derivative is

dy/dx = sin(2x) • 2

dy/dx = 2 sin(2x)

Last week a candle store received $515.90 for selling 30 candles. Small candles sell for $11.25 and large candles sell for $22.40. how many large candles did the store sell?

**Answer:**

16

**Step-by-step explanation:**

x+y=30 solve for x x=30-y

substitute x with 30-y and solve

11.25x+22.4y=515.9

11.25(30-y)+22.4y=515.9

337.5+11.15y=515.9

11.15y=178.4

y=16

**Answer:**

[tex]The \: fraction \: \frac{15}{4} \: is \: equivalent \: to \: 3 \frac{3}{4 } .[/tex]

This fraction is a improper fraction once the absolute value of the top number or numerator (15) is greater than the absolute value of the bottom number or denomintor (4). So, the equivalent fraction is a mixed number which is made up of a whole number (3) and a proper fraction [tex]3 \frac{3}{4} [/tex]

The fraction [tex] \frac{15}{4} [/tex]

is also equal to 15÷4 and can also be expressed as a decimal as 3.75 and expressed as a percentage as 375%.

The **fraction **15/4 is equivalent to 3 3/4.

Here, we have,

To simplify the** fraction** 15/4, you need to find the greatest common divisor (GCD) of the numerator (15) and the denominator (4) and divide both the numerator and denominator by the GCD.

The GCD of 15 and 4 is 1 since there are no **common factors **other than 1.

Dividing both the **numerator **and denominator by 1, we get:

(15 ÷ 1) / (4 ÷ 1) = 15/4

This fraction is a improper fraction once the absolute value of the top number or numerator (15) is greater than the absolute value of the bottom number or denominator (4).

So, the e**quivalent fraction** is a mixed number which is made up of a whole number (3) and a** proper fraction** 3 3/4.

The fraction 15/4 is also equal to 15÷4 and can also be expressed as a decimal as 3.75 and expressed as a percentage as 375%.

A principle at a certain high school claims that the students in her school are above average in SAT. She collects a random sample of 50 students and given an SAT test that provided with a mean score of 541. Is there sufficient evidence statistically to support the principal’s claim? The mean population SAT score is 500 with a standard deviation of 100. SAT scores are normally distributed. Please show all the steps involved in a hypothesis testing including proper statistical symbols, formula used, and report/interpret results in complete sentences.

Using the **z-distribution**, it is found that since the value of the test statistic is greater than the critical value for the right-tailed test, **there is sufficient evidence** to support the principal’s claim.

At the **null hypothesis,** it is tested if they are not above average, that is, their mean is of 500 or below, hence:

[tex]H_0: \mu \leq 500[/tex]

At the **alternative hypothesis**, it is tested if they are above average, that is, their mean is of more than 500, hence:

[tex]H_1: \mu > 500[/tex]

We have the standard deviation for the population, thus, the **z-distribution** is used. The **test statistic** is given by:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

The **parameters **are:

For this problem, the **values **of the parameters are: [tex]\overline{x} = 541, \mu = 500, \sigma = 100, n = 50[/tex]

Hence, the **value **of the test statistic is:

[tex]z = \frac{\overline{x} - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{541 - 500}{\frac{100}{\sqrt{50}}}[/tex]

[tex]z = 2.9[/tex]

The **critical value** for a right-tailed test, as we are testing if the mean is greater than a value, with the standard 0.05 significance level, is of [tex]z^{\ast} = 1.645[/tex].

Since the value of the test statistic is greater than the critical value for the right-tailed test, **there is sufficient evidence** to support the principal’s claim.

c. What is the maximum number of notepads that will fit in 1 closed box

i will give brainliest :)

**Answer:**

a. 810

b. 27

c. 30

**Step-by-step explanation:**

**Part a.**

The volume is 9 * 9 * 10.

9 * 9 = 81, and 81 * 10 = 810.

**Part b.**

The volume of a cube is x^3, where x is the side length of the cube.

If x = 3, then 3^3 = 27.

**Part c.**

If each notebook has a volume of 27, then the maximum amount of notebooks that will fit in a box with volume 810 is 810/27 = 30 notebooks

**a.** The volume of the **rectangular box** is 810 inch³.

**b.** The volume of the notepad is 243 inch³.

**c. **The maximum number of notepads that will fit inside the box is 3.

A cuboid is a three-dimensional closed figure which has volume along with surface area.

The volume of a cuboid is the **product **of its length, width, and height.

The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.

Given, A paper company ships notepads in rectangular boxes that have dimensions measuring 9 inches long, 9 inches wide, and 10 inches tall.

Therefore, The volume of the box is, = (**9×9×10**) inch³.

= 810 inch³.

The dimensions of the notepad are 9 inches by 9 inches with an height of 3 inches.

Therefore, The volume of the notepad is = (**9×9×3**) = 243³ inches.

The maximum number of notepads that will fit inside thebox is,

= (**810/243**).

= 3.33 but it sholud only be 3 notepads.

Melanie is making a piece of jewelry that is in the shape of a right triangle. The two shorter sides of the piece of jewelry are 5 mm and 12 mm. Find the perimeter of the piece of jewelry.

**Answer:**

** 30 mm.**

**Step-by-step explanation:**

The longest side = sqrt(5^2 + 12^2)

= sqrt169

= 13. (Using Pythagoras).

So the perimeter = 5+12+13

=** 30 mm.**

**Perimeter** of the piece of jewelry = 30mm

**Pythagoras** theorem states that “In a **right**-angled triangle, the **square** of the **hypotenuse** side is equal to the **sum** of **squares** of the **other** two sides".

Given,

Shape of jewelry is right angle triangle ABC

length of shorter sides,

AB = 5mm

BC = 12mm

By **Pythagoras** theorem,

AC² = AB²+BC²

AC = √(5² + 12²)

AC = √169

AC = 13 mm

Perimeter of Triangle = AB + BC + AC

= 5 + 12 + 13

Perimeter of Triangle = 30

Hence, 30 mm is the **perimeter** of jewelry.

Q=D(p)=1204−11p, p > 0

Let the market supply of widgets be given by:

Q=S(p)=−3+6p, p > 0

where p is the price and Q is the quantity. The functions D(p) and S(p) give the number of widgets demanded and supplied at a given price.

What is the producer surplus at equilibrium?

Please round the intercept to the nearest tenth and round your answer to the nearest integer.

What is the unmet demand at equilibrium?

Please round your answer to the nearest integer.

**Answer:**

**Step-by-step explanation:**

**I'll use y for quantity and x for price [love my x and y] and rewrite the demand and supply functions:**

**Demand: y=1204−11x**

**Supply: y = -3 + 6x**

**==**

**We want to know the equilibrium price and quantity. The quantities purchased and sold would be equal to the quantities supplied:**

** 1204−11x = -3 + 6x**

**-17x = - 1207**

** x = 71 The price of a widget is 71 units ($, €,£,¥, etc.) at equilibrium**

**A price of 71 would lead to a demand and supply of:**

**y = 1204−11x**

**y = 1204−11(71)**

**y = 423 Widgets**

**We can also plot this to find the point (71,423). See the attachment.**

**At this point, I'm uncertain how to answer the "producer surplus" and "unmet demand" at equilibrium. This is what I did, so please judge if it is correct.**

**The demand line, y=1204−11x, tells us that if the price were 0, the demand would be 1204, which I'll assume in the maximum, since it is stipulated that x > 0 (I imagine it may no longer be a straight line when the price goes into negative territory. I'd be the first in line to accept a widget and $5 if they were priced at -$5).**

**At equilibrium, therefore, we would still have an unmet demand of (1204 - 423) or 781 widgets that customers wanted, but wouldn't pay the price.**

**It seems to me that this would also be the unmet demand: Product that could have been sold, but wasn't, due to the price. I'm unsure, however.**
