check the picture below.

so as you can see, the box is simply 6 rectangles stacked up to each other at the edges.

so we can simply get the area of each rectangle and sum them up and that's the area of the rectangular prism.

\bf \stackrel{\textit{front and back}}{2(19\cdot 7)}+\stackrel{\textit{left and right}}{2(9\cdot 7)}+\stackrel{\textit{top and bottom}}{2(19\cdot 9)}\implies 266+126+342\implies 734

Use the graph that shows the solution to f(x)=g(x) .
n200080 [17]

Answer:

1.  x=3   x=1

2.  x=0

Step-by-step explanation:

We want f(x) to equal g(x)

f(x)=g(x)

1/(x-2) = (x-2)

Using cross products

1 = (x-2) * (x-2)

1 = x^2 -2x-2x+4

Subtract 1 from each side

1-1 = ^2 -2x-2x+4-1

0 = x^2 -4x+3

Factoring

What number multiplies to 3 and adds to -4

-3*-1 = 3

-3+-1 = -4

0= (x-3) (x-1)

Using the zero product property

x-3 =0     x-1=0

x=3   x=1



2.  f(x)=x^2+4x+2

g(x)=(1/2)^ x+1


From the graph,we can see they intersect at x=0

A cylinder circumference 11 pi in and height 10in. What is the volume of the cylinder?
Fiesta28 [93]

Answer:

950.455in^3

Step-by-step explanation:

Given data

Circumference= 11π

Also, the expression for circumference is

C=2πr

11π=2πr

solve for r

r= 11π/2π

r= 5.5in

Given that the Height h= 10in

The expression for the volume is

V= πr^2h

V=3.142*5.5^2*10

V=3.142*30.25*10

V=950.455 in^3

Hence the volume is

950.455in^3

<h2>D. This is an experiment with blocking </h2><h2 />

For your question: "A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half

of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To

determine who listens and who does not, the teacher identifies the two students who scored highest on the last test

and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-

scoring students and continues in this manner until each student has their instructions. Which of the following best

describes this plan?"

The answer is D
