Here's how to rewrite cos^4x tan^2x in the first power of cosine.
See the attached image.
First step, find the trigonometric identity of tan^2x.
Then simply everything until you only get cos x.
Remove all the exponents. Simplify.

Answer:
A. 10
Step-by-step explanation:
I found a website that explains that you need 8.3 grams of coffee to make one 5-fl oz cup of coffee.
To make 600 cups, you need 600 * 8.3 g = 4980 g
Now we convert 4980 g to lb.
1 lb = 454 g
4980 g * (1 lb)/(454 g) = 11 lb
The closest answer is A. 10
Answer: A. 10
Answer:
t=3.5 seconds
Step-by-step explanation:
Given
h(t) = −16t^2 + 111t + 0
h'(t)= -32t + 111
Maximum height occurs when h(t) = 0 and the ball begins to fall
h(t)= -32t + 111=0
-32t + 111=0
-32t=-111
Divide both sides by -32
t=3.46872
Approximately, t=3.5 seconds
Recall,
Maximum height occurs when h(t) = 0
h(t)= -32t + 111=0
= -32(3.46872)+111
= -110.99904+111
= 0.00096 ft
