Answer 1

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

1)

Fact :: Reason

∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE

∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles

∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°

∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°

△CDE ⁓ △ABC :: Same angles (AAA)

2)

Let's solve for AB

sin 30° = 1/2

sin 30° = BC/AB = 15/AB

1/2 = 15/AB ⇒ AB = 30

AB = 30 in

Let's solve for AC (using another way)

AC/12 = 15/8

AC = 12 * 15 / 8   = 22.5

AC = 22.5 in

Graph the inequality x>13.

Answers

———0———13——> was hard to wire on a keyboard but it would be put so 13 is greater then zero and the line would continue to the right side because X is greater and it would be a closed dot on 13 because there is no greater then or equal to nor a less then or equal to im pretty sure haven’t done with in a while but i hope this helps bro

Answer:

The graph is attached.

Step-by-step explanation:

The open circle is because the inequality sign is >. If the sign is > or <, the circle is plotted open. If the sign is [tex]\geq[/tex] or [tex]\leq[/tex], the circle is plotted closed.

The sign is greater than, so the arrow is pointed to the right (where the numbers are going up).

The circle is plotted between 12 and 14 because that is point 13, like the inequality says.

ABCD is a parallelogram.
AD = 12 cm.
DC = 9 cm.
The perpendicular distance of
from CD is 8 cm.
What is the perpendicular distance of AD from BC?

Answers

9514 1404 393

Answer:

  6 cm

Step-by-step explanation:

The area of the parallelogram is the same, either way you figure it.

  A = bh

  A = CD(length ⊥ to CD)

  A = (9 cm)(8 cm) = 72 cm²

__

  A = AD(length ⊥ AD)

  72 cm² = (12 cm)(length ⊥ AD)

  (length ⊥ AD) = (72 cm²)/(12 cm) = 6 cm

The perpendicular distance of AD from BC is 6 cm.

Step-by-step explanation:

The function F represents the revenue in dollars the school can expect to receive if it sells 220-12× coffee mugs for dollars each.

Answers

Options B,D, and E are correct as per the given Function of the revenue.

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

A. At $2 per coffee mug, the revenue will be $196.

This statement is incorrect.

If the price per mug is $2, then the revenue would be (220 - 12x) * 2. If x = 12 (i.e. 12 mugs are sold), then the revenue would be (220 - 12(12)) * 2 = $176.

B. The school expects to sell 160 mugs if the price is $5 each.

This statement is correct.

To find the number of mugs sold at a given price, we need to solve the equation (220 - 12x) * x = revenue, where revenue is the expected revenue at that price.

However, the graph does not provide enough information to determine the number of mugs sold at a price of $5.

C. The school will lose money if it sells the mugs for more than $10 each.

This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases, up to a maximum revenue of about $1,000 when the price is $10 per mug. Therefore, the school will not lose money if it sells the mugs for more than $10 each.

D. The school will earn about $1,000 if it sells the mugs for $10 each.

This statement is correct. The graph shows that the maximum revenue occurs when the price per mug is about $10. At this price, the revenue is approximately $1,000.

E. The revenue will be more than $700 if the price is between $4 and $14.

This statement is correct.

The graph shows that the revenue is increasing in this price range, and the minimum revenue occurs when the price per mug is about $18. Therefore, the revenue will be more than $700 if the price is between $4 and $14.

F. The expected revenue will increase if the price per mug is greater than $10.

This statement is incorrect. The graph shows that the revenue is increasing as the price per mug increases up to $10, but then it starts to decrease. Therefore, the expected revenue will decrease if the price per mug is greater than $10.

The complets table of values for the function rule

x   1    2    4   6

y  22  18   10  2

Completing the table of values for the function rule

From the question, we have the following parameters that can be used in our computation:

y = 26 - 4x

The missing y values are at x = 1, 2, 4 and x = 6

Substitute the known values in the above equation, so, we have the following representation

y = 26 - 4(1) = 22

y = 26 - 4(2) = 18

y = 26 - 4(3) = 10

y = 26 - 4(6) = 2

So, the missing values are 22, 18. 10 and 2
