Julie has a large red apple in her hand that is 4 ft off the ground. A blue bird sees the apple at an
angle of depression of 55°. If Julie is 15 ft from the tree, how tall is the tree?
Answers
Answer:
Step-by-step explanation:
so from the silly drawing, you can see that the triangle is 4 feet off the ground, and that we want to find the Opp side from our angle of 15 °
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
use TOA to find the Opp side of the triangle .. which is labeled X
Tan(15) = X / 15
15* Tan(15) = X
4.019 = X
so the bird is up 4 feet in the tree.. not very high up, plus the 4 feet that the apple is already off the ground, soo
the tree... to where the bird is, at least, is 8.019 feet..
did this make sense? :/
hope the drawing helped :P

Adj = x
Apply trigonometry ratio TOA:
Tan 47 = Opp/Adj
Tan 47 = 25/x
x*Tan 47 = 25
x = 25/Tan 47

If f(1)=6 and f(n)=f(n-1)+2 then find the value of f(6)
Answers
Answer:
Step-by-step explanation:
Answer:
f(6) = 16
Step-by-step explanation:
In the next steps we use this formula : f(n)=f(n-1)+2
Since f(1)=6 then f(2)=f(2-1)+2 = f(1)+2 = 6+2 = 8
f(2)=8 then f(3)=f(3-1)+2 = f(2)+2 = 8+2 = 10
f(3)=10 then f(4)=f(4-1)+2 = f(3)+2 = 10+2 = 12
f(4)=12 then f(5)=f(5-1)+2 = f(4)+2 = 12+2 = 14
f(5)=14 then f(6)=f(5-1)+2 = f(4)+2 = 14+2 = 16.

Charnika has $500 in a savings account at the beginning of the summer. She wants to have at least $200 in the account by the end of the summer. She withdraws $25 each week for food, clothes, and movie tickets. How many weeks can Charnika withdraw money from her account?
A: –10 or less
B: –10 or greater
C: 12 or less
D: 12 or greater
Answers
ANSWER:
D) 12 or greaterStep-by-step explanation:
Total money Charnika has = $500
The money she wants to save = $200
Amount of money she can spend = $ (500 - 200)
= $300
Amount of money withdrawn in every week = $25
The number of weeks the money can be withdrawn = $ (300÷25)
= $ 12

ONM has vertices O (-4, 2), N (3, 6) and M(0,3). What are the coordinates of the
vertices of O' N' M' if ONM is first translated (x, y)+(x + 3, y) followed by a
reflection across the line y = 1?
Answers
Answer:
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].
Step-by-step explanation:
Previously, we have to define a vectorial equation for a reflection across the line [tex]y = 1[/tex]:
Reflection across the line y = 1:
[tex]P'(x,y) = P(x,y) -2\cdot [P(x,y) -(x_{P},1)][/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]x_{P}[/tex] - x-Coordinate of the original point.
[tex]P'(x,y)[/tex] - Resulting point.
Translation:
[tex]P'(x,y) = P(x,y) + (3,0)[/tex] (2)
If we know that [tex]O(x,y) = (-4,2)[/tex], [tex]N(x,y) = (3, 6)[/tex] and [tex]M(x,y) = (0,3)[/tex], then the resulting points are, respectively:
Point O'
Translation
[tex]O'(x,y) = O(x,y) + (3,0)[/tex]
[tex]O'(x,y) = (-1,2)[/tex]
Reflection
[tex]O''(x,y) = O'(x,y) -2\cdot [O'(x,y) -(x_{O'},1)][/tex]
[tex]O''(x,y) = (-1,2) -2\cdot [(-1, 2)-(-1,1)][/tex]
[tex]O''(x,y) = (-1, 0)[/tex]
Point N'
Translation
[tex]N'(x,y) = N(x,y) + (3,0)[/tex]
[tex]N'(x,y) = (6,6)[/tex]
Reflection
[tex]N''(x,y) = N'(x,y) -2\cdot [N'(x,y) -(x_{N'},1)][/tex]
[tex]N''(x,y) = (6,6) - 2\cdot [(6,6)-(6,1)][/tex]
[tex]N''(x,y) = (6,-4)[/tex]
Point M'
Translation
[tex]M'(x,y) = M(x,y) + (3,0)[/tex]
[tex]M(x,y) = (3,3)[/tex]
Reflection
[tex]M''(x,y) = M'(x,y) -2\cdot [M'(x,y) -(x_{M'},1)][/tex]
[tex]M''(x,y) = (3,3) - 2\cdot [(3,3)-(3,1)][/tex]
[tex]M''(x,y) = (3,-1)[/tex]
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].

How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
[tex]A = h*tan(60\°)*/2 = tan(60\°)*h^2/2[/tex]
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Dado que un taxi viaja a una velocidad de 48 mph para llegar a un destino en 2 horas y media, para determinar cuál seria su velocidad si se tarda dos horas para llegar se debe realizar el siguiente cálculo:
48 x 2.5 = 120
120 / 2 = X
60 = X
Así, su velocidad, si se tardase dos horas en llegar, sería de 60 millas por hora.
