9 square units
Step-by-step explanation:
Area of a square = base * height
= 3*3
= 9
The answer is -29, hope this helps
Answer:
C, as q = 62.
Step-by-step explanation:
When you have an equation, your goal is to get the letter you are solving for alone. To do this, you employ a simple rule: what you do to one side of the equals sign, you must do the other.
To isolate q in -55 + q = 7, you must add 55 to the left side. q is now alone. However, because we added 55 to the left side, we must also do it to the right! 7 + 55 = 62, so the new right side is 62. Hence, we get to this:
q = 62
The answer is now in plain sight!
Answer:
<em>Answer: F. 1,275% and 12.75.</em>
Step-by-step explanation:
<u>Ratios</u>
Ratios are usually expressed as decimals, fractions, colon notation, and percentages.
For example, if the ratio of two quantities is 2, it can be expressed as:
2, 2/1, 2:1, 200%
To obtain the percentage expression, just multiply by 100%.
The price of the popcorn sold at a movie theatre was marked up as 12 3/4 times the original cost.
The mixed fraction can be converted to a decimal by just adding their parts as follows:
12 + 3/4 = 12.75
Now to express it as a percentage, multiply by 100%:
12.75 * 100% = 1,275%
Answer: F. 1,275% and 12.75.
The roots routine will return a column vector containing the roots of a polynomial. The general syntax is
z = roots(p)
where p is a vector containing the coefficients of the polynomial ordered in descending powers.
Given a vector
which describes a polynomial
we construct the companion matrix (which has a characteristic polynomial matching the polynomial described by p), and then find the eigenvalues of it (which are the roots of its characteristic polynomial)
Example
Here is an example of finding the roots to the polynomial
--> roots([1 -6 -72 -27])
ans =
12.1229
-5.7345
-0.3884
