Step-by-step explanation:

1) Angles opposite congruent sides in a triangle are congruent, so angle H is congruent to angle D.

2) For the same reason as the first problem, angle D is congruent to angle NSD.

3) Since sides opposite congruent angles in a triangle are congruent, segment AH is congruent to segment AS.

4) For the same reason as the third question, segment SA is congruent to segment SN.

A bag contains 5 red apples and 4 yellow apples. 4 apples are selected at random. Find the probability of selecting 2 red apples

Oksi-84 [34.3K]

Assuming that the apples are not tossed back into the bag after drawing them.

Total of 9 apples.

1st draw yell, 4/9

2nd draw yell, 3/8

3rd draw red, 5/7

4th draw red, 4/6

$\frac{4}{9} * \frac{3}{8} * \frac{5}{7} * \frac{4}{6} = \frac{240}{3024} \\ \\ = \frac{5}{63}$

Please Help? For the function f(x) = 2|x – 1|, what is the average rate of change over the interval –1 ≤ x ≤ 1?

lesya692 [45]

<h3>Answer: -2</h3>

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

Explanation:

Plug in x = -1 to find that

f(x) = 2|x-1|

f(-1) = 2|-1-1|

f(-1) = 2|-2|

f(-1) = 2*(2)

f(-1) = 4

If you repeat for x = 1, you should find that f(1) = 0

--------

Now use the average rate of change formula below. Effectively, we're using the slope formula more or less.

$m = \frac{f(b)-f(a)}{b-a}\\\\m = \frac{f(1)-f(-1)}{1-(-1)}\\\\m = \frac{0-4}{1+1}\\\\m = \frac{-4}{2}\\\\m = -2\\\\$

The average rate of change on this interval is -2

This is the same as finding the slope through the points (-1, 4) and (1, 0).

Last semester Jacob spent 1/3 of an hour doing math homework on each evening that he had math homework.he calculated that he spe

Marina CMI [18]

Jacob had math homework on 81 evenings.

Step-by-step explanation:

Time spent of each evening = 1/3 of an hour

Time spent in minutes = $\frac{1}{3}*60 = 20\ minutes$

Total time spent = 27 hours

Total time spent in minutes = 27*60 = 1620 minutes

Let,

x be the number of evenings spent doing math homework.

Time spent each day* Number of evenings = Total time spent

$20x=1620$

Dividing both sides by 20

$\frac{20x}{20}=\frac{1620}{20}\\x=81$

Jacob had math homework on 81 evenings.
