Write a quadratic equation with the given roots. Write the equation in the form ax2 + bx + c = 0 where a, b, and c are integers.

Vikki [24]

A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20

In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.

x = -2 ----> add 2 to both sides

x + 2 = 0

We can do the same for the other zero.

x = -10 ----> add 10 to both sides

x + 10 = 0

Now that we have both of these, we can multiply these two things together. This will give us the function we need.

f(x) = (x + 2)(x + 10)

f(x) = x^2 + 10x + 2x + 20

f(x) = x^2 + 12x + 20

What is the common ratio of the geometric sequence below?

Vadim26 [7]

Answer:

$\textbf{Option C - $0.1$}\\$

Step-by-step explanation:

$\textup{A geometric series is given by}\\$ a, ar, ar^2, ar^3,. . . , ar^{n-1}, ar^n $ \\\textup{\textbf{Geometric progression or GP is a sequence of numbers in which the next number in the sequence is obtained by multiplying a number to the previous number in the sequence.}}\\$

$\textup{This number is constant through out the sequence and is denoted by $r$. it is given by $r = \frac{ar^n}{ar^{n-1}}$} \\$

$\textup{Here, the given sequence is: $70, 7, 0.7,...$}\\$

$$i.e., a = 70, ar = 7$\\$

$\textup{Hence, $r = \frac{ar}{a} = \frac{7}{70}$ }\\$

$= \frac{1}{10} = 0.1$

6 and 1 over 6 as a decimal

Tema [17]

The numerator in a fraction represents the number of pieces selected. If the numerator is larger than the denominator, the number is larger than one.

The denominator in a fraction represents the total number of equal size pieces that make up a whole.

In the given fraction,the numerator is 1 and the denominator is 6. We have to convert the mixed fraction into an improper fraction.

Therefore, multiply the number of wholes (the whole number) by the number of parts in each whole (the denominator) and then add this product to the number of leftover parts (the numerator).

Now to Convert to a decimal divide the number of parts (the numerator) by the number of parts needed to complete a whole (the denominator).

$6 \dfrac{1}{6}$ as an improper fraction, can be written as $6*6+1$ which is $\dfrac{37}{6}$
37 ÷ 6 = decimal
