simply multiply the speed by the fraction of time
23 × 1/5 = 23/5 = 4 3/5 = 4.6
simply multiply the speed by the fraction of time

The graph of f(x) = 6(0.25)x and its reflection across the y-axis, g(x), are shown.
2 answers:
<u>Answer-</u>
The domain of g(x) is all real numbers.
<u>Solution-</u>
The given function is,
The reflection across y-axis of a point (x, y) will be (-x, y)
So, the reflection of the given function across y-axis will be,
It is an exponential function. The domain of exponential functions is all real numbers and the range is all real numbers greater than zero.
Therefore, first option is correct.

Answer:
d) 87
Step-by-step explanation:
to solve this lets set up the equation
then we multiply 4 on both sides
253+x=340
and subtract 253 on both sides
x=87
to double check take the averages
(87+85+70+98)/4=85
Answer: Choice A
============================================================
Explanation:
Recall that and
. The connection between tangent and cotangent is simply involving the reciprocal
From this, we can say,
In the second to last step, a pair of sine terms cancel. In the last step, a pair of cosine terms cancel.
All of this shows why is identical to
Therefore, is an identity. In mathematics, an identity is when both sides are the same thing for any allowed input in the domain.
You can visually confirm that is the same as
by graphing each function (use x instead of alpha). You should note that both curves use the exact same set of points to form them. In other words, one curve is perfectly on top of the other. I recommend making the curves different colors so you can distinguish them a bit better.
