Answer:
Maggie's answer is going to be approximately 2 miles.
Step-by-step explanation:
Limitation: They may be more expensive and time consuming than lab experiments. Limitation: There is no control over extraneous variables that might bias the results. This makes it difficult for another researcher to replicate the study in exactly the same way.
Answer: Third option is correct.
Step-by-step explanation:
Since we have given that
The graph of the derivative of f(x) , say, y = f'(x), is symmetry about the origin.
so, it is an odd function.
So, f(x) must be an even function.

So, the value of f(-2) is equal to 8.
Hence, Third option is correct.
Answer:
The answer is d.
Step-by-step explanation:
As we know, sin x= cos (90°-x)
sin 18° = cos (90°-18°)
= cos 72°.
Similarly, sin 72°= cos (90°-72°)
= cos 18°
But, sin 55°= cos (90°-55°)
= cos 35°
Answer:
v + u
Step-by-step explanation:
Using the rule of logarithms
log x + log y ⇔ log xy
Given
ln yx, then
ln yx = ln y + ln x = v + u
