Note that
sin(30°) = 1/2
cos(30°) = √3/2
tan(30°) = 1/√3
cos(45°) = 1/√2
tan(45°) = 1
Therefore
5 sin²(30°) + cos²(45°) - 4 tan²(30°)
= 5*(1/4) + 1/2 - 4*(1/3)
= 5/12
= 0.4167
2 sin(30°) cos(30°) + tan(45°)
= 2(1/2)(√3/2) + 1
= 1.866
Answer: 0.223
Answer:
that would be 5 inches
Step-by-step explanation:
if you measure five ft that would be really big, 5 yards is way too big for a cd to be and five miles is 5,280 feet so 5 inches would be the only logic answer
hope this helps!
Hey there! I'm happy to help!
Let's call our percent p. The word is means equals when working with percents. This means we can make the following equation.
10337.6=56.8p
Let's flip the equation so p is on the left.
56.8p=10337.6.
We divide both sides by 56.8.
p=182
To turn a decimal into a percent, you multiply it by 100, so our percent is 18200%.
Have a wonderful day! :D

Hooe that helps!
Answer:
6
Step-by-step explanation:
The correct notation is: Summation from n = 1 to infinity of the expression:
If we expand this notation, we will find that the given summation represent the terms of a G.P and we have to find the sum of infinite terms of a G.P. By placing n=1,2,3,4,... we can find the first few terms as shown below:
Its obvious from the above result, that the given summation represent a G.P with first term equal to 4 and common ratio of 1/3. The formula of infinite G.P is:
Using the value of a1 = 4 and r = 1/3 we can calculate the given summation
Therefore, the given summation is equal to 6.
