S(x) = x^3
Make x the subject:-
x = (S(x))^ 1/3 = ∛ S(x)

Inverse  is ∛ S(x)

An inverse function is formed when you replace y with x, and solve backwads. 
s(x)=x^3
x=y^3
3<span>√x=y
</span>Cube root of x=y 
s^-1(x)=3√x

How do I round 8164 to the 4 decimal point?
aalyn [17]

Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:

8164.45678

In this case, the number rounded to the 4th decimal point (ten thousandths) would be

8164.45680

Because the digit after the 7 is 8, we should round the "78" part to "80".

These two rules will help:

5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)

4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)

Hope this helps! :)

What is the domain of (cd)(x)?
viktelen [127]

Answer:

Only option B is correct, i.e. all real values of x except x = 2.

Step-by-step explanation:

Given the functions are C(x) = 5/(x-2) and D(x) = (x+3)

Finding (C·D)(x) :-

(C·D)(x) = C(x) * D(x)

(C·D)(x) = 5/(x-2) * (x+3)

(C·D)(x) = 5(x+3) / (x-2)

(C·D)(x) = (5x+15) / (x-2)

Let y(x) = (C·D)(x) = (5x+15) / (x-2)

According to definition of functions, the rational functions are defined for all Real values except the one at which denominator is zero.

It means domain will be all Real values except (x-2)≠0 or x≠2.

Hence, only option B is correct, i.e. all real values of x except x = 2.

ZAP is a right triangle, with right angle A and cosP = 4/5. What is sin Z?
irga5000 [103]
If you want to find cosP , since angles Z and P are 2 complementary angles then cosZ is the same as cosP so you say the cosP=sinZ=4/5 (property of 2 complement angles in a right triangle)

F(x)=x2+5x-1 is shifted 3 units left the result is g(x) what is g(x)?
Len [333]
Replace the x in  x^2 + 5x - 1 by x+3:-

g(x) =
(x+3)^2 + 5(x+3) - 1

= x^2 + 6x + 9 + 5x + 15 - 1

= x^2 + 11x + 23

- thats  g(x)

15.48 divided by 12 is 1.29


for sales tax 1.24 divided by 12 is .10
