$y=-1.5 x^{2} +6 \\ \\ x=-3 \Rightarrow y=-1.5*(-3)^2+6 =-1.5*9+6=-13.5+6=-7.5\\ \\x=-2 \Rightarrow y=-1.5*(-2)^2+6 =-1.5*4+6=-6+6=0\\ \\x=-1 \Rightarrow y=-1.5*(-1)^2+6 =-1.5*1+6=-1.5+6=-4.5\\ \\x=0 \Rightarrow y=-1.5*0^2+6 =6$

$x=1 \Rightarrow y=-1.5*(1)^2+6 =-1.5+6=-4.5\\ \\ x= 2 \Rightarrow y=-1.5*2^2+6 =-1.5*4+6=-6+6=0\\ \\x=3 \Rightarrow y=-1.5*3^2+6 =-1.5*9+6=-13.5+6=-7.5$

Answer:

Table 3; Blue graph; y = -4; 2x-3y = 7.

Step-by-step explanation:

Table 3 is a linear relationship because the y-coordinates, or outputs, change by the same rate throughout the table. A constant rate of change defines a linear function.

The blue graph is linear because it is a straight line.

The equation y = -4 is linear because it is the equation of a horizontal line at -4. A function with a line for a graph is linear.

The equation 2x-3y = 7 is linear because it is written in standard form of a linear function, Ax+By = C (in this case A = 2, B = -3 and C = 7).

A right rectangular prism with square bases has a height of 20 centimeters and a volume of 800 cubic centimeters. Which statemen

slamgirl [31]

Answer:

The diagonal of the base is 4√5 centimeters.

The area of a base is 40 square centimeters.

The area of a lateral side between the bases is about 126.5 square centimeters.

Step-by-step explanation:

The volume of any rectangular prism can be found by the formula

volume =B.h

where B = area of base and h is the height of the prism.

It is given the volume of prism is 800 cubic centimeters and height is 20 centimeters.

Substituting these values in the volume formula :

800= B(20)

Or B= 800÷20=40.

Hence area of base is 40 square centimeters.

The diagonal of base = $\sqrt{80}$ = $4\sqrt{5}$

The Volume of prism is 800 cubic unit and base area is 40 square units .Lateral area = area of all sides except the base = 126.5 square centimeters.
