Answer:
A is the answer to your question
Step-by-step explanation:
To do this, just distribute the 3 to each of the coefficient and see if it would result in the same coefficients in the original expression.
C
Step-by-step explanation:
15/16-3/8 is equal to 0.5625. One half is 0.5 answer C is closest.
Using simpler trigonometric identities, the given identity was proven below.
<h3>
How to solve the trigonometric identity?</h3>
Remember that:

Then the identity can be rewritten as:

Now we can multiply both sides by cos⁴(x) to get:

Now we can use the identity:
sin²(x) + cos²(x) = 1

Thus, the identity was proven.

Answer:
7³
Step-by-step explanation:
You could answer this after a quick inspection. 7 remains constant as t approaches 8. Each of the (t -1) terms will approach 7. So, multiplying these factors together, you'll get 7(7)(7) = 7³3 as your answer, the limit as t approaches 8 of the given expression.
44 inches.
All you have to do is find out what 10% of 40 is then add it back to 40. In the case of finding 10% of something you just “chop” of the back number (or move the decimal place forward) so 10% of 40 is 4. The. 40+4=44.
You can also multiply fractions to find the percent of a number but that is not necessary in this case.
