Answer:
1200 in²
Step-by-step explanation:
The surface area of the prism is the sum of the lateral area and the areas of the bases.
__
<h3>lateral area</h3>
The lateral area is the total area of the three rectangular faces. It can be computed from ...
LA = Ph
where P is the perimeter of the triangular base, and h is the height of the prism (the distance between triangular bases).
The perimeter is the sum of the edge lengths of the base:
P = 30 in + 17 in + 17 in = 64 in
Then the lateral area is ...
LA = (64 in)(15 in) = 960 in²
__
<h3>base area</h3>
The two bases are congruent triangles, so have a total area of ...
A = 2(1/2bh) = bh
where b is the base of the triangle, and h is its height.
A = (30 in)(8 in) = 240 in²
__
<h3>total surface area</h3>
The sum of lateral area and base area is ...
total area = (960 in²) +(240 in²) = 1200 in²
The surface area of the triangular prism is 1200 square inches.
Answer:
0.73 yrs
Step-by-step explanation:
if t is time in years
quarterly
600 = 200(1 + 0.06625/4)^4t
3 = (1 + 0.06625/4)^4t
ln3 = 4tln(1. + 06625/4)
t = ln3 / (4ln1.0165625)
t = 16.7198 yrs
continuously
600 = 200e^(0.06875t)
3 = e^(0.06875t)
ln3 = 0.06875t
t = ln3 / 0.06875
t = 15.9798 years
Δt = 16.7198 - 15.9798 = 0.73 yrs
A.
2.718... between 2 and 3
2 = √4 and 3 = √9
So, 2.718... between √4 and √9 [√4 < e < √9]
b.
π = 3.1415...
3.1415... between 3 and 4
3 = √9 and 4 = √16
So, 3.1415... between √9 and √16 [√4 < π < √9]
