Answer:

4 × 3 - 3^2 + 1 × 8 = 11/1 = 11

Step-by-step explanation:

Multiple: 4 * 3 = 12

Exponentiation: 3 ^ 2 = 9

Subtract: the result of step No. 1 - the result of step No. 2 = 12 - 9 = 3

Multiple: 1 * 8 = 8

Add: the result of step No. 3 + the result of step No. 4 = 3 + 8 = 11

Answer:

look below

Step-by-step explanation:

y = 2 (x + 3)^2 - 2

Geometric figure:  parabola

Alternate forms:

y = 2 (x + 2) (x + 4)

y = 2 (x^2 + 6 x + 8)

-2 x^2 - 12 x + y - 16 = 0

Expanded form:

y = 2 x^2 + 12 x + 16

Roots:

x = -4

x = -2

<u>Properties as a real function: </u>

Domain - R (all real numbers)

Range - {y element R : y>=-2}

Partial derivatives:

d/dx(2 (x + 3)^2 - 2) = 4 (x + 3)

d/dy(2 (x + 3)^2 - 2) = 0

Implicit derivatives:

(dx(y))/(dy) = 1/(12 + 4 x)

(dy(x))/(dx) = 4 (3 + x)

Global minimum:

min{2 (x + 3)^2 - 2} = -2 at x = -3

How do you convert a mixed fraction to an improper fraction ?
maks197457 [2]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

a\frac{b}{c} ----> a mixed number

a is a integer

b/c < 1

so

a\frac{b}{c}=a+\frac{b}{c}

Adds the integer plus the fraction

\frac{ac+b}{c} ---> an improper fraction

\frac{ac+b}{c} > 1
