Law of Cosine/Sine problem.

1 answer:

4 0

Either or can be used with any triangle...I personally find the law of sines is often more compact as in this case we can just say;

(sin115)/18=(sin40)/c (with no need for b or B as would be needed with the law of cosines...)

c=18(sin40)/(sin115)

c≈12.77

Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)

finlep [7]

Answer:

g(f(x))=x^2 + 14x + 48

Step-by-step explanation:

you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.

A truck driver drove 48 miles in 45 minutes.At this rate,how many miles can the truck drive in one hour?

murzikaleks [220]

Answer:

64 miles

Step-by-step explanation:

Number of miles driven in 45 minutes = 48 miles

We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.

Number of miles driven in 1 minute = miles

Since, 1 hour = 60 minutes, we can write:

The number of miles driven in 1 hour (60 minutes) = miles

This means the truck driver can drive 64 miles in an hour.
