Answer:
228.4cm²
Step-by-step explanation:
Find the diagram attached
Total surface area of the prism = Ph + 2B
P is the perimeter of the base (triangle)
h is the height of the prism
B is Base area
P = 5cm + 5cm + 4cm
P = 14cm
h = 15cm
B = 1/2 * base * height
B = 1/2 * 4.6 * 4
B = 4.6 * 2
B = 9.2cm²
Substitute the values into the formula;
Total surface area of the prism = Ph + 2B
Total surface area of the prism = 14(15)+2(9.2)
Total surface area of the prism = 210 + 18.4
Total surface area of the prism = 228.4cm²
Hence the total surface area of the triangular prism is 228.4cm²
Answer:
-3<x<3
Step-by-step explanation:
let y=0
0=x^2-9
0=(x+3)(x-3)
x=-3 and x=+3
The amplitude of this function is 4/5. Be sure you understand why that is so.
Answer:
So information at the bottom:
since every number in a thousand spot needs to have 3 digest, we need to add a zero onto 29,422,33<u>0</u>. If we didn’t add a zero, then the problem wouldn’t make much since. So if we divide 29,422,330 by 2, our answer would be 14,711,165. A whole bunch of numbers, but nothing that can’t be solved!
