Answer:
1) c/d = pi
Step-by-step explanation:
since c= pi x d
divide both sides by d
c/d = pi
ANSWER
y=x
y=x³
EXPLANATION
A function, f(x) has an inverse if and only if
Thus, the function is one to one.
For y=x or
Hence this function has an inverse.
For the function y=x² or f(x)=x².
This function has no inverse on the entire real numbers.
For the function y=x³ or f(x)=x³
This function also has an inverse.
For y=x⁴ or f(x) =x⁴
This function has no inverse over the entire real numbers.
Answer: f(-3) = -27 & f(3) = 27
Step-by-step explanation:
(-3)^3
-27
(3)^3
27
Answer:
12
Step-by-step explanation:
12 beacuse We assume, that the number 48 is 100% - because it's the output value of the task.
x is the value we are looking for
Now we have two simple equations:
1) 48=100%
2) x=25%
48/x=100%/25%
Now we just have to solve the simple equation, and we will get the solution we are looking for.
Solution for what is 25% of 48
48/x=100/25
(48/x)*x=(100/25)*x - we multiply both sides of the equation by x
48=4*x - we divide both sides of the equation by (4) to get x
48/4=x
12=x
x=12
now we have:
25% of 48=12
Answer:
C. It is an angle that has its vertex at the center of a circle.
Step-by-step explanation:
That's the definition.
A. is wrong. An angle with a measure greater than 180° is an obtuse angle,
B. is wrong. An angle that has its vertex on the circle is an inscribed angle.
D. is wrong. Part of the circumference of a circle is an arc.
