Write the expression in factored form s^2-20s-100

KatRina [158]

Answer:

The factors of given expression are 10+10√2 and 10-10√2.

Step-by-step explanation:

We have given a quadratic expression.

s²-20s-100

We have to find factors of given expression.

We use quadratic formula to find factors.

x = (-b±√b²-4ac) / 2a

From given expression, a = 1 , b = -20 and c = -100

Putting values in above formula, we have

x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)

x = (20±√400+400 ) / 2

x = (20±√800) / 2

x = (20± √400×2) / 2

x = (20±20√2) / 2

x = 10±10√2

Hence, the factors of given expression are 10+10√2 and 10-10√2.

The parent cosine function is transformed to create the function . which graphed function has the same amplitude as function m?

Shkiper50 [21]

Based on the graph given, the option that will show the same amplitude as function m is graph D.

<h3>Which graphed function is this about?</h3>

The cosine function is seen as:

f(x) = A*cos(kx) + M

And the functions are:

A stands for amplitude,
k is angular frequency,
M is the midline.

When the function is m(x) = -2*cos(x+π).

The absolute value of the amplitude will be 2*|-2| = 4

Therefore, the option that can have the requirement above is graph D.

What is -1.1 repeating as a fraction

Thepotemich [5.8K]

$Hey \\ There!$

$\frac{-1.1}{1} ( \frac{10}{10} )\\ \\ -1.1(10) = -11 \\ \\ 1(10)= 10 \\ \\ \\ Fraction: \frac{-11}{10}$ this is also $equal$ to: $-1\frac{1}{10}$

Your answer would probably be: $\frac{-11}{10} = -1\frac{1}{10}$

Good luck on your assignment and enjoy your day!
