A UFO is coming in to pick up some test subjects. Their elevation above the ground is 60,000 feet. Their laser sights tell them that a direct (diagonal) path to the nearest landing area is 90,000 feet away. What is the angle of depression as they come in to land?
Answer:
41.83°
Step-by-step explanation:
It is given that :
The vertical distance of the UFO from the ground = 60,000 feet
The diagonal distance of the landing area to the UFO = 90,000 feet
In order to find the angle of depression, we have to use the trigonometric ratios, i.e.,
[tex]$\sin \ \theta = \frac{\text{perpendicular distance}}{\text{hypotenus}}$[/tex]
[tex]$\sin \ \theta = \frac{60,000}{90,000}$[/tex]
[tex]$\sin \ \theta = \frac{2}{3}$[/tex]
[tex]$\sin \ \theta = 0.667$[/tex]
∴ [tex]$\theta = \sin^{-1 }(0.667)$[/tex]
= 41.83°

Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
Answer:
Step-by-step explanation:
Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
THIS IS THE COMPLETE QUESTION BELOW;
1. Explain how you calculate the net force in any direction on the box.
2. Suppose an upward force of 15 N is added to the box. What will be the net vertical force on the box?
3. What force could be applied to the box to make the net force in the horizontal direction zero? Explain.
4. Suppose a force of 25 N to the right is added to the box. What will be the net force to the right?
CHECK THE ATTACHMENT FOR THE FIQURE.
1)since the given horizontal forces are acting on the box at opposite direction then
NET FORCE= (100- 50)N
= 50N( this is because the 100N and 50N acting Horizontally will cancel each other, then the remaining force is 50N.
✓Since, the two vertical forces also acted on the box in opposite direction, then
NET FORCE= (25 25)N
= 0N
Note: horizontal forces are one acting from right to left and vice versa, while vertical forces are ones acting from up to down and vice versa.
HENCE, NET FORCE = 50N + 0N= 50N
2) since the net vertical force was 0N, if
15N force is added then we still have NET FORCE OF 15N
3) if force of 50N is applied to horizontal forces moving from left to right then NET HORIZONTAL FORCES= 0N
4) since, the net force for the box is 50N, if Horizontal force of 25N is added moving left to right then NET FORCE = 25N for whole box.

An African elephant weighed 209 lbs when it was born. Baby elephants gain an average of 38 lbs per week.
Part A
Write an equation that could be used to calculate the number of weeks, w, it would take a baby elephant to weigh 1197 lbs.
Part B
How many weeks will it take for the baby elephant to weigh 1197lbs?
Enter your equation, your answer, and your work or explanation in the space provided.
Answer:
Part A: W= (1197- 209)/ 38
Part B: 26 Weeks
Step-by-step explanation:
Part A:
We first need to subtract the 209lbs from the goal of 1197lbs. Now we have how many pounds we need to gain. Then we need to divide it by how many pounds we are gaining a week. Now we have how many weeks it will take
Part B:
W= (1197- 209)/ 38
W= 988/ 38
W= 26

The ratio of two number is 4:9.When 5 is subtracted from each of them,the new ratio becomes 3:8. Find the numbers.
Answer:
The numbers are 20 and 45
Step-by-step explanation:
Let the two numbers be a and b
The ratio of the two is 4:9
That means;
a/b = 4/9
9a = 4b •••••(i)
secondly;
Subtracting 5 from each gives a ratio of 3:8
(a-5)/(b-5) = 3/8
8(a-5) = 3(b-5)
8a - 40 = 3b - 15
3b - 15 + 40 = 8a
3b + 25 = 8a
a = (3b + 25)/8 •••(ii)
Insert this into 1
9(3b + 25)/8 = 4b
27b + 225 = 32b
32b - 27b = 225
5b = 225
b = 225/5
b = 45
From i;
9a = 4b
9a = 4 * 45
a = 4 * 45/9
a = 20

Find f(x) and g(x) so that the function can be described as y = f(g(x)).
y = Four divided by x squared. + 9
a) f(x) = x + 9, g(x) = Four divided by x squared.
b)f(x) = x, g(x) = Four divided by x. + 9
c)f(x) = One divided by x., g(x) = Four divided by x. + 9
d)f(x) = Four divided by x squared., g(x) = 9
the answer is Y/g
y=fgx
y/g=fx,which mines f(x)=y/g

When two angles of an isosceles triangle are given in the form of x, then the value of a single angle can have two possible outcomes those are:
X can be [tex]56.66^\circ[/tex]X can be [tex]53.33^\circ[/tex]Given,
Two angles: X and [tex]\rm{X}+10[/tex]
As we know in an Isosceles triangle, the sum of all the angles is equal to[tex]180^\circ[/tex] and any of the two angles can be equal.
There can be two possible outcomes:
Case 1. When the two equal angles are X
[tex]\begin{aligned}\text{X}+\text{X}+(\text{X+10})&=180\\3\text{X}+10&=180\\3\text{X}&=180-10\\\text{X}&=\dfrac{170}{3}\\\text{X}&=56.66^\circ\end{aligned}[/tex]
Case 2: When the two equal angles are [tex]\rm{X}+10[/tex]
[tex]\begin{aligned}\text{X}+(\text{X}+10)+(\text{X}+10)&=180\\3\text{X}+20&=180\\3\text{X}&=180-20\\\text{X}&=\dfrac{160}{3}\\\text{X}&=53.33^\circ\end{aligned}[/tex]
Therefore, the two possible values of X can be [tex]56.66^\circ[/tex] and [tex]53.33^\circ[/tex]

Can someone please check my answer for this function???
Answer:
You're wrong, it's the bottom left
Step-by-step explanation:
x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.
