I know I'm in middle school but i can help you.The answer is 12 your correct.
Answer:
15/2
Step-by-step explanation:
Hello,
the area of a triangle is b*h/2
we can set BC as the base because AC is harder to calculate.
Then we draw an imaginary height.
There's no way to really explain, but the height would be 5 here, since 3 - -2 = 5
The base is 3
3*5/2 = 15/2

The value of constant of variation "k" is
Solution:
Given that the direct variation is:
y = kx ----- eqn 1
Where "k" is the constant of variation
Given that the point is (5, 8)
To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1
Thus the value of constant of variation "k" is k = 8/5 or 1.6
I hope this is correct and helps!
Answer:
48 miles.
Step-by-step explanation:
A bus travels 36 miles in 45 minutes
In 60 minutes, travelling at this rate, the bus would cover:
× 36 miles = 48 miles
Not going to do (1), (2), (3) since they are implicit from (a) and (b) and require graphs (which aren't supported on brainly).
We have 
, that means, if plug in 
we get

Doman of cosine is ![x\in[0,1]](https://tex.z-dn.net/?f=x%5Cin%5B0%2C1%5D)

Hope this helps.
