Answer:
23.6
Step-by-step explanation:
<u><em>Finding AC:</em></u>
Cos 61 = 
0.48 × 10 = Adjacent
AC = 4.8
<u><em>Now, CB:</em></u>
Cos 29 =
0.87 × 10 = CB
CB = 8.8
<u><em>The perimeter:</em></u>
=> 10+4.8+8.8
=> 23.6
The inequality is TRUE because when you substitute 4 into each variable (p), you will have this:
3(4) > 5 + 4
12 > 9
12 is greater than 9, so the inequality is definitely true.

The domain of a function is the set of all possible inputs for the function.
What are the domain and range?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Let y = f(x) be a function with an independent variable x and a dependent variable y.
If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of the function.
The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x).
Hence, the domain of a function is the set of all possible inputs for the function.

Answer: 1.9166
Step-by-step explanation:
Let 
be the population mean.
By considering the given description, we have
n=20
s=7
Since, the population standard deviation is unknown , so we use t-test.
Test statistic : 
i.e . 
[Rounded to four decimal places.]
Hence, the value of the t-test statistic : 1.9166
Answer:
7b^3 + 9b^2 + 8b
Step-by-step explanation:
Combine like terms
My teacher taught me a few years ago to put like terms in the same format so they're easier to combine:
b^3 + <em>7b </em>+ <u>9b^2</u> + <em>b </em>+ 6b^3
Here I have all terms to the 3rd power bolded, all terms to the 2nd power underlined, and all terms to the 1st power italicized. That makes it easier to combine those that are similar
b^3+ 6b^3 = 7b^3
<u>9b^2</u> - remains the same
<em>7b </em>+ <em>b = 8b</em>
Now just reorder them to where the exponents are listed from greatest to least:
7b^3 + 9b^2 + 8b
