Answer:

Step-by-step exAnswer:(-2, 2)

Step-by-step explanation:

7q² - 28 = 0

Add 28 to bothside

7q² - 28 + 28 = 0+ 28

7q² = 28

Divide bothside by 7

7q² / 7 = 28/7

q² = 4

Take the square root of bothside

√q² = ±√4

q = ± 2

q = -2 or q =2

q = (-2, 2)

A cab driver drove west 2.4 miles. He then drove 6.83 miles east. How far and in which direction did he end up from his starting
frosja888 [35]
Because the cab driver drove west and then east, it must be east for the direction he ends up in. We then see that the answer is A because the west is negative so you subtract from the number of miles he drove east, instead of adding. So, once again, the answer is A:+4.43

Solve for x. Round your answer to the nearest hundredth.
vlabodo [156]

Step-by-step explanation:

sin 53° = x/26

0.7986 = x/26

=> x = 26×0.7986

= 20.76

Tan 39° = 52/x

0.8098 = 52/x

=> x = 52/0.8098

= 64.21

cos x = 7/15 = 0.4667

x= arc cos 0.4667 = 62.18°

sin x = 27/46 = 0.5870

x = arc sin 0.5870 =35.94°
