Answer:
Step-by-step explanation:
There is a few ways to go about doing this problem. I am going to setup a function.
x = seconds
f(x) = distance = How far
f(x) = (3.0* 10^8) x
Insert 10^5 where x is located
(3.0* 10^8) x
Multiply
(3.0* 10^8) (10^5)
Do the math
(3.0* 10^8) (10^5) = 3 * 10^13
Answer:
-120/119
Step-by-step explanation:
cos α = -5/13 = adj/hyp
using Pythagoras theorem
hypotenuse ² = opposite² + adjacent ²
13² =opp²+ (-5)²
169 = opp² + 25
169-25 = 144 = opp²
opp = √144 = 12
sinα = opp/hyp = -12/13
sin β = -12/13
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ)
cos α = -5/13
sinα = 12/13
tanα= sinα/cosα = 12/13 / -5/13 = 12/-5 = -12/5
sin β = -12/13
cos β = 5/13
tan β = sinβ/cosβ = -12/13 / 5/13 = -12/5
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ)
tanα = -12/5
tanβ= -12/5
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ) = (-12/5+(-12/5))/(1-(-12/5)(-12/5))
(-12/5+(-12/5)) = -12-12/5 = -24/5
(1-(-12/5)(-12/5)) = 1-(144/25) = (25-144)/25 = 119/25
tan(α+β) = (tanα + tanβ)/ (1-tanαtanβ) = (-12/5+(-12/5))/(1-(-12/5)(-12/5)) =-24/5/119/25 = -24/5 x 25/119 = -24x5/119 = -120/119
The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.
As the perimeter lies along the edges of squares and we count 16 sides of squares as we work around the perimeter,
this means that each square is
160 / 16 = 10 ft on a side.
so 10 ft in real life plots to 1 unit on the drawing
If the scale is changed to 20 :1 ,
then the drawing would be exactly the same shape, only each side would have half the original drawing units.
In stead of a 40 ft side being represented by 40 ft / 10 ft/unit = 4 units,
That side would be 40 ft / 20 ft/unit = 2 units
Hence, The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.

In this context, g is the independent variable and u is the dependent variable.
Explanation:
A variable is classified as the independent variable if its value is being controlled or manipulated. Conversely, a variable is classified as the dependent variable if its value is being observed or measured. In this context, based on the given statements, it is clear that g is the independent variable and u is the dependent variable.
Therefore, the correct options are: g is the independent variable and u is the dependent variable.
Answer:
1) g is the dependent variable.(A)
2) u is the independent variable.(D)
Step-by-step explanation:
of angle x?
Answer:
A.) 48°
Step-by-step explanation:
There is a right angle and an angle of 42°
Therefore
x=180-90-42. (sum of int angles of triangle)
x=48°
Answer:
(A) 48
Step-by-step explanation:
Triangles have 180°, so all you have to do is subtract the numbers you already know from 180.
180-42 = 138
The square on the left corner means that degree is a right angle. Right angles are always 90°.
138-90 = 48degrees
