X is less than -2, so -2 is our largest value of the interval, so it goes on the right. Since there is no lower endpoint (it is ALL values less than -2), we put the negative infinity symbol on the left side. The curved end on -2 indicates an open interval

PLEASE HELP WITH THE FOLLOWING. WILL GIVE BRAINLIEST. THANK YOU
Marina86 [1]

Answer:

<h2>50.8°</h2>

Step-by-step explanation:

First, we need to use the Pythagorean Theorem to find the third side. We will then use the law of cosines to find the angle.

2√15² = 2√6² + b²

60 = 24 + b²

Subtract 24

36 = b²

b = 6

Now, that we have all three sides, we will use the law of cosines to figure out the angle.

c² = a² + b² - 2abCosC°

Substitute the values in.

6² = 2√15² + 2√6² - 2(2√15)(2√6)CosC°

36 = 60 + 24 - 2(37.947331922)CosC°

36 = 60 + 24 - 75.894663844CosC°

36 = 84 - 75.894663844CosC°

Subtract 84

-48 = -75.9CosC°

0.63241106719 = CosC°

Arccos (0.63241106719) = 50.77176844°

The largest acute angle is approximately 50.8°

In a class of 32
Alika [10]

There are 28 right handed students in class

<em><u>Solution:</u></em>

Given that, there are 32 students in a class

The ratio  of left-handed  students to right-  handed students is  1 : 7

Let the number of left handed students be 1x

Let the number of right handed students be 7x

<em><u>To find: Number of right handed students in school</u></em>

Total number of students = 32

number of left handed students + number of right handed students = 32

1x + 7x = 32

8x = 32

x = 4

number of right handed students = 7x = 7(4) = 28

There there are 28 right handed students in class

Which other expression has the same value as (-14 ) - 8? Explain your reasoning
Yakvenalex [24]
D has the same answer. D has the same answer, because a means -14 + 8 which equals -6 which isn’t equal to the answer to the first one (-22). The next one you switch the - to a + and the -8 to 8 so it would equal 22. C equals -6 which also doesn’t equals the first one. So the last one is right because one you add to negative so still end up with a negative.
