Make the u substitution
u=x^2
du=x dx
it should simplify the problem
Answer:
<em>Answer: C</em>
Step-by-step explanation:
<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:

Both the amplitude A and the angular frequency w of a cosine can be modeled by the function

The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:

Thus:

Therefore, the equation of the sinusoid is:

Answer: C

cause I say so.
Answer:
D
Step-by-step explanation:
It says she spent $7.53 at the store and she bought (SOME) cereal for $3.67
so we have to find how much the 6 peaches cost. To find it out we are going to have to subtract the cereal she bought from $3.67 and the money she wasted total so its going to be D.
Answer:
Step-by-step explanation:
Use Pythagoras theorem
a = √ 8² + 5² = 9.4
b = √ 17² - 12² = 12.0
