Hiya, you didn't post a picture of the triangular prism. If you don't know how, you can just give me the measurements of each side and I'll help solve it for you :)
A and C
Step-by-step explanation:
Im sorry I've got homework too
Answer:
a.) Between 0.5 and 3 seconds.
Step-by-step explanation:
So I just went ahead and graphed this quadratic on Desmos so you could have an idea of what this looks like. A negative quadratic, and we're trying to find when the graph's y-values are greater than 26.
If you look at the graph, you can easily see that the quadratic crosses y = 26 at x-values 0.5 and 3. And, you can see that the quadratic's graph is actually above y = 26 between these two values, 0.5 and 3.
Because we know that the quadratic's graph models the projectile's motion, we can conclude that the projectile will also be above 26 feet between 0.5 and 3 seconds.
So, the answer is a.) between 0.5 and 3 seconds.
The surface area of the prism is the sum of surface areas of 3 rectangles and 2 triangles.
The surface area of rectangles are
.
The sum is
.
The are of each triangle is .
The sum of areas of 2 triangles is .
The surface area of the prism is
.
OH DONT COPY THIS M8
THIS IS WRONG
