Sarah measures the length of elevation to the top of a tree as 23.6 degree from where she is standing at a point 250 meters from

it's base.Her eye level, where the angle measurement was taken is 1.5 meters above the ground level.assuming the ground is horizontal, fine the height of the tree.

The height of the tree is 110.7  meters.

<u>Step-by-step explanation</u>:

Form a triangle with an angle 23.6  and base 250 meters and height x meters.

From the triangle,

tan (23.6) = Opposite / Adjacent

tan (23.6) = x / 250

x = 250 tan(23.6)

⇒ 250 0.436889

⇒ 109.2 m

x = 109.2 m

The height of the tree = x+1.5

                                     = 109.2+1.5

                                     = 110.7 m

Point A has coordinate A(3, 2). The point is rotated 180° clockwise about the origin. What is the x-coordinate of point A’?
Ivenika [448]

Answer:

Step-by-step explanation:

A 180 degree rotation around the origin would be the same things as a reflection across the x-axis followed by a reflection across the y-axis.

This would result in the new location being (-3, -2)  The x coordinate is -3.

Use what you've learned in this unit to model the population of Western
nekit [7.7K]

The population function of the Western Lowland Gorillas can either represent population growth or population decay

<h3>How to model the population</h3>

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

y = a(1 \pm r)^x

Where:

  • (a) represent the initial value i.e. the initial population of the Western Lowland Gorillas
  • (r) represents the rate at which the population increases or decreases.
  • (x) represents the number of years since 2022
  • (y) represents the population in x years

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

y = 2000 * 0.98^x

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

|2x-8| + 3 = 5 two solutions
Delicious77 [7]

Answer:

The two solutions are 5 and 3

Step-by-step explanation:

The equation of the absolute has two solutions because IxI = a means x = a and x = -a

Let us solve the question using this fact

∵ I2x - 8I + 3 = 5

→ Subtract 3 from both sides

∴ I2x - 8I + 3 - 5 = 5 - 3

∴ I2x - 8I = 2

By using the fact above

→ 1st solution

∵ 2x - 8 = 2

→ Add 8 to both sides

∴ 2x - 8 + 8 = 2 + 8

∴ 2x = 10

→ Divide both sides by 2 to find x

∴ x = 5

→ 2nd solution

∵ 2x - 8 = -2

→ Add 8 to both sides

∴ 2x - 8 + 8 = -2 + 8

∴ 2x = 6

→ Divide both sides by 2 to find x

∴ x = 3

∴ The two solutions are 5 and 3

The teacher separated her class of twenty-eight students into two groups. One group has 4 more than twice as many students as th
wariber [46]
4+2x = x (x = student in smaller group)

4 + 2x + x = 28 (total # of students)
4+ 3x = 28
3x = 24
x = 8
8 students in the smaller group 
4 + 2(8) = 20 students in the larger group
