Find the surface area of the right rectangular prism shown below. units²
faust18 [17]

Answer:

67 units^2

Step-by-step explanation:

The surface area of the prism is found by

SA = 2 ( lw+lh + wh)

     = 2 ( 5*1.5+ 4*1.5 + 5*4)

     = 2 ( 7.5+6+20)

     = 2 (33.5)

Hi!

To solve this, we must make an equation in y = mx + b form, where m is the slope and b is the y-intercept.

Since we are looking at a graph with points, it saves us a TON of work, and all we have to do is simply look at the graph. We only need to find m and b, that's it!

M is the slope, and the slope can be represented by the change between points on a line, also known as <em>rise/run. </em>

If we start at point (-4, -1), and go to point (-2, 0), we can see that it goes up 1 and right 2, which would be represented as 1/2.

B is the y-intercept, and that is simply the point that is on the y-axis, which is the point (0, 1), so our number would be 1.

Therefore, plugging these numbers into the equation, our equation is y = <em>1/2</em>x + <em>1</em>

<em></em>

Hope this helps! :D

Which is the midpoint of the segment joining (12, 2) and (-5, – 7)?
Rainbow [258]

Answer:

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )

Step-by-step explanation:

Midpoint of line segment is calculated as

m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )  -----------(1)

Here

(x_1, y_1) = (12,2) \ \  and \ \ (x_2, y_2) = (-5, -7)

Substituting values in equation (1)

m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )

m(x, y)=(\frac{7}{2} , -\frac{5}{2} )
