Answer:

1 solution

Step-by-step explanation:

y =  - 3 \\ y =  -  x - 4 \\  =  >  - 3 =  - x - 4 \\  =  >  - x - 4 + 3 = 0 \\  =  >  - x - 1 = 0 \\  =  >  - x = 1 \\  =  > x =  - 1

Which of the following statements would be correct to use when proving that limx→4(3x−4)=8?
Fudgin [204]

Answer:

Option c

Step-by-step explanation:

given that limit x tending to 4 of the function (3x-4) is 8

This implies for all values of x such that for epsilon >0 arbitrary small ,

||x-4||, we get

|f(x)-8|<3epsilon

this is equivalent to the option c.

Proof:

Consider

||x-4||

Hence it follows that option C is right.

2. The volume of both of these trapezoidal prisms is 24 cubic units. Their
Valentin [98]

Answer:

area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively

Step-by-step explanation:

Let us first be aware of formula of volume for any regular geometrical figure.

Fundamental formula for  volume for any regular geometrical figure is.

volume = area of cross section of object*  height of object (A)

In the problem stated area of cross section of object will be  area of a trapezoidal base.

Given in the question is

Volume of both the trapezoidal prisms = 24 cubic units

*************************************************************************************

For prism with height 6 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 6 * area of a trapezoidal base

=> area of a trapezoidal base = 24/6 = 4 square units

*************************************************************************************

For prism with height 8 unit

Substituting the value of height and volume in formula for trapezoidal prisms

24 = 8 * area of a trapezoidal base

=> area of a trapezoidal base = 24/8 = 3 square units

*************************************************************************************

Therefore area of a trapezoidal base  of each prism with heights  6 and 8 units are 4 square units and 3 square units respectively.
