Can you help me with these questions​

Mathematics
1 answer:
dlinn [17]3 years ago

Answer:

see below (I hope this helps!)

Step-by-step explanation:

41. √20 = √4 * 5 = √4 * √5 = 2√5

43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.

45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x

47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.

An electronics store has two options for liquidating televisions that have not sold.
Oksanka [162]
Answser: first option <span>350(0.95)^x + 30x - 350

Explanation:

You can figure out the </span><span>function that shows the difference in price between option 1 and option 2 if you make a table simulating the behavior for a few months:

month                 price as per option 1          price as per option 2

start                     350                                     350

1                          350 - 5% (350) =                350 - 30
                            = 350 (0,95)

2                          350 (0,95)×(0,95) =
                            350 (0,95)²                         350 - 30(2)

3                           350 (0,95)³                        350 - 30(3)

So now you can figure out the price with each option after x months:

                             350 (0.95)ˣ                        350 - 30x

And the difference is 350 (0.95)ˣ - [350 - 30x]

Which, expanding the square brackets, is 350 (0.95)ˣ + 30x - 350 ↔ the first option.
