If you are currently 326 feet in the air, what is the angle of depression from you to your friend?
Answers
The angle of depression from you to your friend is 54.1°
Trigonometric ratios
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let θ represent the angle between me in air and my friend, hence:
tanθ = 326 / 450
θ = 35.9 degrees
The angle of depression = 90 - 35.9 = 54.1°
The angle of depression from you to your friend is 54.1°

2 5/6 + (-1 4/12) =
Answers
Answer:
1.5 as decimal, 1 1/2 as a fraction
Step-by-step explanation:
1. convert 2 5/6 & (-1 4/12) to a improper fraction.
17/6 and -16/12
2. multiply 17/6 by 2 to match -16/12's denominator
17/6 * 2 = 34/12
We now have
34/12 + -16/12
A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.
We have:
[tex]\frac{34}{12}-\frac{16}{12}[/tex]
Now solve. 34-16 = 18
our answer is 18/12

A normal distribution (X) has a mean of 100 and a standard deviation of 10.
What is the probability that X will be smaller than 80?
Use the Normal Table and keep all 4 decimal positions in your answer.
Answers
Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that X will be smaller than 80.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of [tex]\mu = 100[/tex].The standard deviation is of [tex]\sigma = 10[/tex].The probability that X will be smaller than 80 is the p-value of Z when X = 80, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{80 - 100}{10}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% probability that X will be smaller than 80.

Write an equation of the circle with center (-6, 2) and diameter 10.
Answers
Answer:
it something i know that much
Step-by-step explanation:
Solution:
We know that the formula to write the equation of a circle is (x – h)² + (y – k)² = r², where:
h = x coordinatek = y-coordinater = radius of circleCenter of circle: (-6,2)First, let's find the radius of the circle. We know that the diameter of the circle is ten units. The radius is half of the diameter. This means that the radius is five units because it is half the diameter, which is ten units.
Diameter: 10 unitsRadius: 10/2 units = 5 unitsCreating the equation:
(x – h)² + (y – k)² = r²=> (x + 6)² + (y – 2)² = 5²Hence, the equation to form a circle with center (-6, 2) and diameter 10 is (x + 6)² + (y – 2)² = 5².

You Are Graphing Rectangle ABCD In The Coordinate Plane. The Following Are Three Of The Vertices Of The Rectangle A(3,5) B(3,−4) C(−2,−4)
Answers
Answer:
D(-2,5)
Step-by-step explanation:
Point D has the same x coordinate as point C and has the same y coordinate as the point A
Hi!
We want to find the x and y value for point D.
We can see that point C is the same amount to the left as point D. That means they will have the same x-value.
Furthermore, we can see that point A is the same amount up as point D. That means that they will have the same y-value.
We will use the given coordinates, (x, y).
-------------------------------------------------------------------------------------------------------------
The x-value of point C is -2, and the y-value of point A is 5.
That means that the coordinates of point D are (-2, 5).

Find the equation of the line that contains the point (4,-2) and is perpendicular to the line y=-2x+8.
Answers
Answer:
[tex]\frac{1}{2} x - 4[/tex]
Step-by-step explanation:
Perpendicular lines will have slopes that are the multiplicative additive inverse of each other: a line with slope 3/4 is perpendicular to a line with slope -4/3, for example. You need a line that is perpendicular to a line with slope -2 (reading that from the -2 in the -2x portion of the given equation, which is written in slope-intercept form), so your new line must have slope +1/2.
With the slope and a point, we can come up with an equation using this formula:
y - y-coordinate = slope (x - x-coordinate)
So we have y - (-2) = 1/2 (x - 4).
Simplify the equation: y + 2 = 1/2 x - 2
Subtract 2 from both sides: y + 2 - 2 = 1/2 x - 2 - 2
Simplify: y = 1/2 x - 4.
