Answer:

22/7 is not pi

Step-by-step explanation:

22/7 is just a close approximation for pi, not pi itself.

If you put 22/7 into a calculator, you get:

3.142857...

While the number pi itself is:

3.1415926...

You can notice that pi is actually different than 22/7, even though the two numbers start out the same and are close to each other. Frequently in geometry, you use 22/7 as pi because it's so close and makes calculation easier.

Hope this helps!

Given the function f(x) = -2c+cx-x^2, and f^-1(5) = -1, find c
AnnZ [28]

Answer:

c=-2

Step-by-step explanation:

We are given the function:

f(x) = -2c + cx - x^2

And that:

\displaystyle f^{-1} (5) = -1

And we want to determine the value of <em>c</em>.

Recall that by definition of inverse functions:

\displaystyle \text{If } f(a) = b, \text{ then } f^{-1}(b) = a

So, since f⁻¹(5) = -1, then f(-1) = 5.

Substitute:

f(-1) = 5 = -2c + c(-1) - (-1)^2

Simplify:

5 = -2c - c - (1)

Combine like terms:

6 = -3c

And divide. Hence:

c = -2

In conclusion, the value of <em>c</em> is -2.

1. If 4.75x = 12.35, what is the value of x? 2. What is 3x +2+ 4x - 1 after combining like terms?
eimsori [14]

Answer:

1. x = 2.6

2. 7x + 1

Step-by-step explanation:

1.

Given:

4.75x = 12.35

Find x

4.75x = 12.35

Divide both sides by the coefficient of x, that is 4.75

4.75x / 4.75 = 12.35 / 4.75

x = 2.6

Check

4.75x = 12.35

4.75(2.6) = 12.35

12.35 = 12.35

2.

Given:

3x + 2 + 4x - 1

Combine like terms

3x + 4x + 2 - 1

7x + 1
