ANSWER
(C)38.16
EXPLANATION
The acute angle given in the right triangle is 27°.
The side length adjacent to the 27° angle is 34 units.
The side length we want to find is x units, which is the hypotenuse of the right triangle.
We use the cosine ratio to obtain:
Solve for x,
to the nearest hundredth.
Answer:
It is unlikely to have thunderstorms tomorrow
Step-by-step explanation:
20% chance mean 20/100 = 0.2
The probability of having the even is 0.2
Remember of the probability of having an even is 0 -0.5 then the event is unlikely to happen
if the probability is 0.5 we have a 50% chance of the even happening
If the probability is 0.5 to 1 then the event is likely to happen
If the probability is 1, that event will happen
Answer: 42
explanation : 90-48=41
A good estimate for a door in a public setting is about 4 feet
Answer:
Step-by-step explanation:
cos^2+sin^2 = 1 ( rule)
cos^4x-cos^2x simplify
- cos^2( -cos^2 +1 ) -cos^2 common
or -cos^2 ( 1-cos^2)
since cos^2 + sin^2 = 1
substitute : -cos^2 ( sin^2 )
substitute : -(1-sin^2 ) ( sin^2)
multiply : -sin^2 + sin^4 or sin^4 - sin^2
it is verified that sin^4 -sin^2= cos^4-cos^2
