What graph there is not one
Answer:
1/a+b+c=1/a+1/b+1/c
Step-by-step explanation: I could be wrong but I tried.
Answer:
- 175 radio ads
- 10 television ads
- 595,000 people
Step-by-step explanation:
Radio ads reach 3000/200 = 15 people per dollar.
Television ads reach 7000/500 = 14 people per dollar.
Except for the constraints on the number of TV ads, the best value for the advertising dollar comes from radio ads.
So, we must satisfy the constraint that 10 TV ads are the minimum. Then the remaining 35,000 in advertising budget can be spent on 175 radio ads. The number of people reached by this advertising will be ...
175·3000 +10·7000 = 595,000 . . . people
10 TV ads and 175 radio ads should be used. This campaign will reach 595,000 people.

This graph is drawn so the feasible region is white. Areas outside the feasible region are shaded. (This approach can make identifying the feasible region easier.) The object is to get the objective function line as far from the origin as possible. The feasible region vertex (175, 10) does that.
Answers:
- d) vertical
- c) alternate interior
- f) supplementary
- e) alternate exterior
- g) corresponding
- e) alternate exterior
- f) supplementary
- c) alternate interior
- e) alternate exterior
Letters 'a', b, and h are never used.
Letters c and f show up twice each; e shows up 3 times.
=====================================================
Explanations:
- Angles 1 and 2 are vertical angles because they are opposite one another in this X configuration. Vertical angles are always congruent.
- These angles are alternate interior angles because they are inside the parallel lines (hence the "interior") and they are on alternating sides of the transversal cut.
- The two angles shown here form a straight line, so that's what makes them supplementary. Supplementary angles add to 180 degrees.
- Angle 4 and angle 5 are on alternating sides of the transversal, but this time they are outside the parallel lines. So that's why we go for alternate exterior this time.
- Angles 5 and 6 are in the same southwest corner of each four-corner configuration, which makes them corresponding angles.
- It's the same idea as problem 4
- Same idea as problem 3.
- Same idea as problem 2.
- Same idea as problems 4 and 6.
---------------
None of the angle pairs mentioned are consecutive interior angles. These types of angles are on the same side of the transversal, and inside the parallel lines. So we never use option 'a'. We cross off option h as well for pretty much identical reasoning. Options 'a' and h are the same thing, just slightly different wording.
We cross off option b as well because none of the angles add up to 90 degrees.
first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!
since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1
please mark as brainliest!
