2. A highway makes an angle of 6 with the horizontal. This angle is maintained for a horizontal distance of 5 miles. To the nearest hundredth of a mile, how high does the highway rise in this 5-mile section? Show the steps you use to find the distance.

Answers

given:
angle of 6 : i'm assuming this is 6 degrees.
distance of 5 miles.

tan(6) = rise/5 mi
rise = 5 mi * tan(6)
rise = 5 mi * 0.10510423526
rise = 0.52552117632

rise = 0.53 miles.

Solve each of the following equations for x.a) 3x - 8 =29 b) 3 ( x - 8 ) = 28

c) 3 (x - 8) + 17 =29 d) 7x + 12 = 3x - 8

Answers

3x - 8 =29 \n \n 3x = 29 + 8 \ / \ add \ 8 \ to \ each \ side \n \n 3x = 37 \ / \ simplify \n \n x = (37)/(3) \ / \ divide \ each \ side \ by \ 3 \n \n Answer: \fbox {x = 37/3} \ or \ \fbox {x = 12.3333}

7x + 12 = 3x - 8 \n \n 7x + 12 - 3x = -8 \ / \ subtract \ 3x \ from \ each \ side \n \n 4x + 12 = -8 \ / \ simplify \n \n 4x = -8 - 12 \ / \ subtract \ 12 \ from \ each \ side \n \n 4x = -20 \ / \ simplify \n \n x = - (20)/(4) \ / \ divide \ each \ side \ by \ 4 \n \n x = -5 \ / \ simplify \n \n Answer: \fbox {x = -5}

Geoff planted dahlias in his garden. Dahlias have bulbs that divide and reproduce underground. In the first year, Geoff’s garden produced 8 bulbs. In the second year, it produced 16 bulbs, and in the third year it produced 32 bulbs. If this pattern continues, how many bulbs should Geoff expect in the sixth year?A. 64
B. 512
C. 128
D. 256

Answers

1st = 8, 2nd = 16, 3rd = 32, doubling each time so 4th = 64, 5th = 128,

6th = 256

A scientist uses a submarine to study ocean life.• She begins at sea level, which is an elevation of o feet.
She travels down 31.6 feet.
• She then ascends 19.2 feet.
Next, she travels down a second time, 89.5 feet.
How many feet must she now ascend to get back to sea level?

Answers

since she is now 101.9 below sea level she will now need to ascend/go up 101.9 to reach sea level
