What is the surface area for this triangular prism?

Mathematics
1 answer:
malfutka [58]3 years ago
7 0

Answer:

52 cm^2

Step-by-step explanation:

To find the rectangular area on the bottom you multiply 3 by 5 = 15 cm^2.

To find the triangular area on the sides you multiply 4 by 3 = 12 cm^2 then divide by 2 = 6 cm^2, but since there are 2 of them you multiply by 2 again and end up with a surface area of 12 cm^2.

To find the square area on the top you multiply 5 by 5 = 25 cm^2.

So the total surface area is 25+15+12 = 52 cm^2.

<em>Note: cm^2 represents cm squared</em>

The equation that is represented by the graph below is y = e^x - 4.

<h3>How to illustrate the graph?</h3>

From the graph, it can be seen that the only exponential function n to hat intercept the function at equal to 3 is y = e^x - 4.

Let's equate y to 0.

y = e^x - 4.

e^x - 4 = 0

e^x = 4

In(e^x) = In(4)

x = 1.386

The x intercept is located at (1.386, 0).

In conclusion, the correct option is D.

Reggie, Alvin, and Jose are member of a relay running team. Reggie finished his leg of the race 2.45 seconds faster than Alvin a
lorasvet [3.4K]
From the given, we expressed the time that each of the team members ran in mathematical expression.
 
                Reggie = 57.12 seconds
                 Alvin = 57.12 + 2.45 seconds = 59.57 seconds
                 Jose = 57.12 - 3.81 seconds = 53.31 seconds
We then sum up all the time we calculate to determine the total time for the team. The answer is therefore 170 seconds.
