Answer:
circumference=2πr=2×π×12.5=78.5cmis your answer
1/3 x 1/5 = 1/15 in its simplest form
Range for the given Exponential function
is f(x) > 0.
the correction option is a). f(x) > 0
The function given in, the question is exponential function is given by
Which is an exponential function. The domain of the give function is (-∞, ∞).
<h3 /><h3>what is exponential function?</h3>
The function which is in format f(x) =
where, a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
the Question seems to be incomplete. And options could be
a) f(x) > 0 c) f(x) ≤ 0
b) f(x) < 0 d) f(x) ≥ 0
Simplification of the given equation


clearly, the range of the exponential function is f(x) > 0.

Answer:
x=84
Step-by-step explanation:
We know that the angles in a triangle are equal to 180.
39+57+x=180
96+x=180
x=84
