Answer:
62.2° (or 1.1 rad)
Step-by-step explanation:
Let’s call the three points A Allen’s house, B Bob’s house, T the traffic light and α “angle of depression”.
Since we have a right triangle BTA, let’s first find out the angle ∡BTA based on its opposite side AB = 7 km and the hyponenuse TA = 15 km.
∡BTA = arcsin(AB/TA) ≈ arcsin(0.4667) ≈ 0.4855 rad or 27.82°
Now since the text says the connecting line TA “is vertical to the road”, α is the rest of the right angle when ∡BTA subtracted.
α ≈ 90° - 27.82° = 62.18°
or α ≈ 0.5 π rad - 0.4855 rad ≈ 1.09 rad
See above for properly rounded values.

A = 76.8 yd²
Step-by-step explanation:
The area (A) of a regular polygon is calculated as
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
Here p = 8 × 4 = 32 yd and a = 4.8 yd , then
A = [tex]\frac{1}{2}[/tex] × 32 × 4.8 = 16 × 4.8 = 76.8 yd²

X+y=12
Get the y alone, so subtract x by each side to get y= -x+12
Then fill in the equation: 4x + (-x+12)=33, remove the parenthesis and solve to get 3x+12=33. Then subtract 12 from both sides to get 3x=21. Now divide 3x from both sides to get x=7 now, use this x answer for the previous equation, x+y=12. Fill in the x so now it’s (7) + y=12
And then subtract 7 from both sides to get y=5. So for the first slide, x=7 and y=5
For the next slide, you already have y= -x+15. Fill this in for the equation 3x+2y=36. 3x+2(-x+15)=36 distribute to get 3x+-2x+30=36. Subtract the x’s to get an equation of x+30=36. Subtract 30 from both sides to get x=6 and use this for the other equation, y= -x+15 to get y= -6 + 15, which equals y=9. x=6 and y=9

Step-by-step explanation:
Answer: C x-int: 0.5. y-int: 1
Step-by-step explanation:
We first see the y-int of the graph, where x equal to 0.
Based on the graph, y is passed the y-axis on the positive sign, which means that y-int is (0,1), only b and c fits.
And we can clearly see the x-int is on the positive sign also, which is (0.5,0), c is the answer.

Alex got a iPhone 11 for Christmas as a present. After spending 3 hours on the iPhone Alex decided to walk down the stairs to get a snack in the kitchen, but then he fell down the stairs because he was paying attention to the iPhone.

Answer:
The difference between iPhone 11 and Spinal cord repairence is 99,300$.
Step-by-step explanation:
To be honest, this is a really weird question. But a spinal cord injury can cost up to 100,000$ a year. And an iPhone 11 cost around 700$. It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol. And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.

Leann works at a restaurant for dinner there is a choice of three main dishes and two sides main dish Burger chicken pasta sides Apple fry Rena list possible ways a person could order your main dinner see this these combination is in the correct you to drop down menu to explain your reasoning
Answers
Answer:
(a) Leann is incorrect
(b) For every main dish, there are 3 sides
(c) 6 selections
Step-by-step explanation:
See attachment for complete question
Given
Main Dish: Burger (B), Chicken (C), Pasta (P)
Sides: Apple (A), Fries (F)
Solving (a): Is Leann list correct?
From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP
This list is incorrect because:
AB is the same BA, BF is the same as FB and so on
Solving (b): Number of sides for each Main dish
From the question:
[tex]Main\ dish = 2[/tex]
[tex]Sides = 3[/tex]
This implies that:
For every main dish, there are 3 sides
Solving (c): Total number of selection
In (b), we have:
[tex]Main\ dish = 2[/tex]
[tex]Sides = 3[/tex]
So: the total is:
[tex]Total = Main\ dish * Sides[/tex]
[tex]Total = 2 * 3[/tex]
[tex]Total = 6[/tex]
