Answer:
Hes correct with number 1 aka answer A
Step-by-step explanation:
Its talking abt in the middle hes suppose to divide the six bc at the end it will have 1/8-1/8-1/8 and 2 negatives make a positive meaning it would be 2/8-1/8=1/8 there for number 1 aka A is right btw i want brainiest for explanation thx :)
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
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.

1. Is the graph proportional?
2. How many feet can a sloth travel in 20 minutes?
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.

ASAP Please answer. Three students sit in the first row. In the second row, 3 students sit behind each of those students, and so on. Write an expression with exponents to show how many students sit in the third row? How many total students are seated?
Answer:
3^2, 9 students.
Step-by-step explanation:
I'm not 100 percent sure about this but I'm pretty sure that because there are 3 rows you can just do 3^2 which is 9.
Answer:
3^x. 39
Step-by-step explanation:
To find the expression, we know the first row is 3 and the next row is 9. So the pattern is multiply by 3. That means the expression is 3^x. Following that, we know the third row is 27. 3 + 9 + 27 = 39
