What is the surface area of this triangular prism rounded to the nearest tenth?

finlep [7]

Answer:

The surface area of the triangular prism is $145.3$ $ft^2$

Step-by-step explanation:

Step 1: Finding the two area of two triangles

Area of the triangle = $\frac{1}{2} (base \times height})$

Area of the triangle = $\frac{1}{2} (9.8\times 5.33})$

Area of the triangle = 26.117

Area of 2 triangles = $52.234$

Step 2: Finding the area of the side rectangles

Area of the rectangle = $length \times breadth$

Area of the rectangle 1 = $6.2 \times 3.8$ = 23.56 $ft^2$

Area of the rectangle 2 = $8.5 \times 3.8$ = 32.3 $ft^2$

Area of the rectangle 3 = $9.8 \times 3.8$ = 37.24 $ft^2$

Step 3: surface area of the triangular prism.

Surface area of the triangular prism = 52.234 + 23.56 + 32.3 + 37.24

Surface area of the triangular prism = 145.334 $ft^2$

What is the slope of the line through (1,0)(1,0)left parenthesis, 1, comma, 0, right parenthesis and (3,8)(3,8)left parenthesis,

Lemur [1.5K]

Answer: The slope is $4$

Step-by-step explanation:

The following formula is used to find the slope of a line:

$m=\frac{y_2-y_1}{x_2-x_1}$

You know that that line passes through these points:

$(1,0)\ and\ (3,8)$

Then you can identify that:

$y_2=0\\y_1=8\\\\x_2=1\\x_1=3$

Knowing these values you can substiute them into the formula $m=\frac{y_2-y_1}{x_2-x_1}$ and evaluate, in order to find the slope of this line.

This is:

$m=\frac{0-8}{1-3}\\\\m=\frac{-8}{-2}\\\\m=4$
