Ok, so the first thing you should do is collect like-terms.


7x+3+6x+11

Combine 7x and 6x ---> You'll get 13x.


So it'll be 13x + 3 + 11

Now you'll combine 3 + 11 and you'll get 14.

The answer should be 13x + 14


I hope this helped ^^*

Combine like terms.

Since 7x and 6x both have a variable of x, you can combine them.

7x + 6x = 13x

After that, you are left with:

13x + 11 + 3

You also have two numbers without variables; 11 and 3. You can also combine those.

11 + 3 = 14

So, your final answer would be:

13x + 14

To which interval would we restrict f(x) = cos (x-π/4) so that f(x) is invertible?
nadezda [96]

Answer:

The range of x values for which y is unique is 2·π

Step-by-step explanation:

For a function j: X → Y to be invertible, we have that for every y in Y, there is associated only one x which is an element of x

Hence, f(x) = cos(x - π/4) gives

the x intercept at two penultimate points of the graph of cos(x - π/4) are;

x = 2.36, and x = 8.64

x = 3/4·π, and x = 2.75·π = 2\tfrac{3}{4}\cdot \pi

Hence the range of x values for which y is unique is presented as follows

2\tfrac{3}{4}\cdot \pi - \frac{3}{4}\cdot \pi = 2}\cdot \pi

The range of x values for which y is unique = 2·π.

/viewform?hr submission=Chclk4feKBIQ.
Gennadij [26K]

Answer:

c) .22

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

In this question:

\sigma = 2.5, n = 500

Then

M = z*\frac{\sigma}{\sqrt{n}}

M = 1.96*\frac{2.5}{\sqrt{500}}

M = 0.22
