How to solve shaded regions on a trapezoid is simple.
First find the area of the whole trapezoid, or W but it already gives us that as 21.66 in squared.
Next, find the area of the non shaded region, or NS.
3.8*4.6=17.48 in
Lastly, subtract the NS from the W.
21.66 -17.48 = 
NS= 17.48 in squared.
W= 21.66 in squared.
S= 4.18 in squared.
 
The answer is B- 4.18 in Squared

14c³d²-21c²d³/14cd

= (196c^4d³-21c²d³)/ 14cd

= (196c³d²-21cd²)/14

= (28c³d²-3cd²)/2

What is the domain and range? ex. (-4, infinity) Please this is for a grade
WITCHER [35]

Problem 2

<h3>Answers:</h3><h3>Domain = [-2, 2)</h3><h3>Range = {-2, -1, 0, 1, 2}</h3>

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

Explanation:

The domain is the set of allowed x inputs of a function. We see that the left most point is when x = -2, so -2 is the smallest value allowed in the domain. On the opposite side of the spectrum, we see that x = 2 is the right most value. However, x = 2 is not allowed in the domain because of the open hole here. This is why we use a curved parenthesis for this part. Whereas a square bracket for -2 tells the reader "-2 is part of the domain". The answer you wrote down is very close. Just change the second square bracket to a curved parenthesis.

For the range, we simply have 5 possible y value outputs and they are: -2 -1, 0, 1 or 2. No other y values are possible. Since we have so few items in the range, we just list the values and put them between curly braces to indicate we have a set of values. We cannot do this with the domain as there are infinitely many items in the domain (eg: x = 1.27 and x = 2.339 are in the domain).

V125BC [204]

Answer:

<u>The company needs to sell at least  93 guitars for a total revenue of $  11,160 to start making a profit.</u>

Correct statement and question:

A music company is introducing a new line of acoustic guitars next quarter. These are the cost and revenue functions,  where x represents the number of guitars to be manufactured and sold:

r(x) = 120x

c(x) = 100x + 1,840

The company needs to sell at least  ___________ guitars for a total revenue of $  __________ to start making a profit.

Source:

Question that can be found at e-eduanswers dot com. Can't copy and paste the URL because brainly will block it.

Step-by-step explanation:

Let's recall the formula of the break-even point:

Revenue - Cost = 0

Revenue = Cost

Replacing with the information we know, for solving for x:

120x = 100x + 1,840

120x - 100x = 1,840

20x = 1,840

x = 1,840/20

x = 92

If the company needs to sell at least 92 guitars to reach the break-even point, selling 93 will allow them to start making a profit.

r(93) = 120 * 93 = 11,160

c(93) = 100 * 93 + 1,840 = 11,140

Profit = 11,160 - 11,140 = 20

Change the given quantity to the indicated unit. Round the answer to the nearest tenth of the unit if necessary. 48 qt ≈ _______
Murljashka [212]
The answer is 43.6 liters

Explanation:
So we want to find out how many liters are in 48 quarts. The first step would be to find other how many liters are in 1 qt, which is about 0.95 liters. Now that we know there are 0.95 liters in 1 qt, to solve for 48 qts, we multiply by 0.95. 0.95 x 48 = 45.6. Since 43.6 is closest to our rounded answer, 45.6, there are about 43.6 liters in 48 qts.
