Answer: 2, 6

<u>Step-by-step explanation:</u>

Triangle Inequality Theorem states that the sum of two sides must be GREATER than the third side.

RS + ST > RT and RS + RT > ST and ST + RT > RS

2x + 4x > 12 2x + 12 > 4x 4x + 12 > 2x

6x > 12 12 > 2x 12 > -2x

x > 2 6 > x -6 < x

2 < x x < 6 invalid

Answer: 2 < x < 6

Graph: O----------------------O

2 6

<em> Note: -6 is invalid because you cannot have a negative length. </em>

What is the maximum number of relative extrema contained in the graph of this function f(x)=3x^3-x^2+4x-2

Sergeeva-Olga [200]

The maximum number of turning points in a cubic function is 2.

In this case,

$f(x)=3x^3-x^2+4x-2\implies f'(x)=9x^2-2x+4$

The discriminant is $(-2)^2-4(9)(4)=-140$ , which means the derivative has no real roots. This means there are no critical points and thus no turning points/relative extrema.

Please any help is necessary

Answer:

Option D. 50 ft

Step-by-step explanation:

we know that

The area of the figure is equal to the area of three rectangles

so

$A=18x+(48-36)(32-11)+(18)(32)$

$A=18x+(12)(21)+(18)(32)\\A=18x+828$

Remember that the area is given

$A= 1,728\ ft^2$

so

$18x+828=1,728$

solve for x

$18x=1,728-828\\18x=900\\x=50\ ft$

Answer:

C is correct

Step-by-step explanation:

Given: System of linear inequality

$y$

$y\geq 2x+3$

First we will draw the graph of system of equation and then see the correct option.

Equation 1: $y$

We will make the table.

x : -2 0 2

y : 1 0 -1

Test Point: (0,4)

0<-2 ( False )

Shaded area away from (0,4)

Equation 2: $y\geq 2x+3$

We will make the table.

x : -2 0 2

y : -1 3 7

Test Point: (0,4)

4≥3 ( True )

Shaded area towards (0,4)

Please see attachment for graph.

Hence, C is common shaded area (region)
