Answer:

<h2> decreasing: (-2, -1)∪(-1, 0) </h2>

Step-by-step explanation:

From x = -2 to x = 0 function is decreasing, but for x= -1 function doesn't exist, so we need to exclude x = -1 from (-2, 0)

Convert from Decimal Notation to Scientific Notation

umka21 [38]

Answer:

Hence, 0.026 can be expressed as $2.6 \times 10^{-2}$ .

Step-by-step explanation:

- Given 0.026

- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .

- Then count n and write in scientific notation.

Step 1 of 1

Consider 0.026

$\Rightarrow 2.6$

Decimal has moved 2 places to right.

The power will be negative as original no. is less than 1 .

$\begin{aligned}&2.6 \times 10^{-2} \\&0.026=2.6 \times 10^{-2} .\end{aligned}$

If the discriminant is positive how many solutions are there

ddd [48]

Answer:

$b^2-4ac>0$ yields 2 real roots

Step-by-step explanation:

To find the number of real roots for a quadratic, we apply the discriminate. The discriminate is the inside portion of the square root from the quadratic formula.

• $b^2-4ac>0$ yields 2 real roots

• $b^2-4ac=0$ yields 1 real root

• [tx]b^2-4ac<0[/tex] yields no real roots

Example:

$4x^2-7x+2=0$ where a=4, b=-7, and c=2

$b^2-4ac=(-7)^2-4(4)(2)=49-32=17$ .

It has 2 real roots
