A plane is moving north st 120 km/h
Answer:
D. cosine
Step-by-step explanation:
As it can be seen in the figure, the triangle ABC is a right-angled triangle with Angle C = 90 degree.
In a right angle triangle, there is a formula as following:
<em>cosine (of an acute angle) = length of adjacent side/ length of hypotenuse</em>
In the figure, the point of angle B and length of hypotenuse AB are given.
We have to calculate x - length of the given side. As BC is the adjacent side of angle B
=> we can use the above formula to calculate x
So that we can use cosine
If we double the costs, then we are going to stretch the graph vertically (B). Here is why. If the cost was $6 in 2010 then it doubles in 2011 the new cost would be $12 for the same amount of refrigerators in 2010. Thus the stretch vertically
Answer:
-3.73
Step-by-step explanation:
solution:
Given:
Angle between two lines=60⁰
slope of first line=1
Or, tanA=1
Or, A= tan inverse (1)
so, A=45⁰
so, angle of inclination of first line=45⁰
Now,
angle of inclination of second line= A+ 60⁰
= 45⁰+60⁰
=105⁰
so, slope of second line = tan105.
= -3.73
Answer:
1.2
Step-by-step explanation:
Gradient = y2-y1/x2-x1
Coordinates = (4,6), (-16,-18)
-18 - 6/-16 - 4
-24/ -20
= 1.2
Hope it helps.
