Answer:

Step-by-step explanation:

1.) y= 1/5x - 2

2.) y = 1x + 2

3.) y = 2x + 4

4.) y = 1x + 4

5.) y = 1/3x - 4

6.) y = 1/2x - 3

1) y=1/5x-2
2) y=-1x+2
3)y=-7/3x+4
4) y=-1x+4
5)y=1/3x-4
6)y=-1/2x-3

Answer:

c = -75/14 OR c = -5.357143

Step-by-step explanation:

Simplify both equations:

1.2x + 7 - 5x =

-3.8x + 7

2.2c - 3 = 2(6 - c) + 7c =

c = −5.357143

Answer:

x= 35° hope this helps!!!

Answer: 35°

Step-by-step explanation: the total of a triangle's angles always equals 180° and we know 2 of the angles so if you add the two (55+90=145) and subtract that from 180 (145-180=35) you get 35°

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50° angle
of elevation. His eyes are 5 feet above the ground. Using cos 50° 0.64, what is the height of the tree
to the nearest foot?

36 feet
29 feet
24 feet
31 feet

Answers

Answer:

[tex] \tan(50) =opp(x) \div adh(20) \\ \tan50 \times 20 = opp(h) \\ = 23.8 [/tex]

therefore the answer is 24

The height of the tree is approximately 26 feet.

What are trigonometric identities?

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Let's denote the height of the tree with 'h'.

Then we can use the trigonometric ratio for cosine as follows:

cos(50°) = adjacent/hypotenuse

cos(50°) = 20/h + 5 (the adjacent side is the distance from the student's eyes to the tree, which is 20 feet, and the hypotenuse is the height of the tree plus the height of the student's eyes, which is h + 5 feet)

Now we can solve for 'h':

0.64 = 20/(h + 5)

0.64(h + 5) = 20

0.64h + 3.2 = 20

0.64h = 16.8

h = 26.25

So the height of the tree is approximately 26 feet (rounded to the nearest foot), which means the closest answer choice is 29 feet.

Therefore,

The height of the tree is approximately 26 feet.

Find the LCM for 6 and 8

Answers

Answer:

24

Step-by-step explanation:

The LCM of 6 and 8 is 24 because 24 is the smallest number that is both a multiple of 6 and a multiple of 8

Answer:

Step-by-step explanation:

To find the least common factor....

Let's list the factors of each number

6: 1, 2, 3, 6

8: 1, 2, 4, 8

So in this case, the '2' is common and the least (after 1 ofc but 1 doesn't count)

can i pls get help on wat 2x - 3 = 15?

Answers

Answer: x = 9

Step-by-step explanation:

Step 1: Add 3 to both sides.

2x − 3 + 3 = 15 + 3

2x = 18

Step 2: Divide both sides by 2.

2x/2 = 18/2

x = 9

The answer is 9.

You’d move all terms that don’t contain x to the right side and solve it.

1. Is the graph proportional?

2. How many feet can a sloth travel in 20 minutes?

Answers

Answer:

1. Yes

2. 60

Step-by-step explanation:

The graph is proportional because it passes an origin point.

The equation of the graph is

[tex]y = 3x \: \: (x \geqslant 0) \: \: (y \geqslant 0)[/tex]

We can find the distance when travelling in 20 minutes by substituting x = 20 in the equation.

[tex]y = 3(20) \\ y = 60[/tex]

Therefore the distance (ft) is 60.
