Answer:
acute
Step-by-step explanation:
Evaluate the angle C = (11x + 85)/3 at x = 13:
C(13) = (143 + 85)/3, or 76 degrees. This is an acute angle (more than 0 and less than 90 degrees).
Answer:
The answer is 9.43 cm.
Step-by-step explanation:
The formula for circumference is πd or 2πr.
The diameter is the radius times 2. 1.5 times 2 is 3.
3 times π is about 9.43.
I hope this helps! :)
Answer:
Step-by-step explanation:
missing angle is 113 degree because the relation between 113 degree and missing angle is that they are alternate interior angle and alternate interior are always equal.
Answer:
<em>The domain of f is (-∞,4)</em>
Step-by-step explanation:
<u>Domain of a Function</u>
The domain of a function f is the set of all the values that the input variable can take so the function exists.
We are given the function

It's a rational function which denominator cannot be 0. In the denominator, there is a square root whose radicand cannot be negative, that is, 4-x must be positive or zero, but the previous restriction takes out 0 from the domain, thus:
4 - x > 0
Subtracting 4:
- x > -4
Multiplying by -1 and swapping the inequality sign:
x < 4
Thus the domain of f is (-∞,4)
