what is the meaning of ^ this sign
The surface area of triangular prism is 117.12 mm²
<u>Explanation:</u>
Base side, a = 9 mm
Base side, b = 6.6 mm
Base side, c = 5.2 mm
Height, h = 4 mm
Total surface area = ?
We know,
Surface area, A = 2 Ab ( a+b+c) h
Ab = √s(s-a) (s-b) (s-c)
s = a+b+c/2
Solving for A
A = ah + b h + ch + 1/2 √ -a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2 (b c)² - c⁴
A = 9.4 + 6.6 X 4 + 5.2 X 4 + 1//2 √ -9⁴ + 2(9 X 6.6)² + 2(9 X 5.2)² - (6.6)⁴ + 2 (6.6 X 5.2)² - (5.2)⁴
A = 117.12 mm²
Therefore, the surface area of triangular prism is 117.12 mm²
Answer:
it is 2, 4, AND 5:)
Step-by-step explanation:
Your answer would be:
596.64 = 596.640
Reasoning= If you just take away the zero from 596.640 you would have the same answer as 596.64. Now if you add a zero to 596.64 you still would have the same answer, therefore they are equal.
Hope this helps! (:
Answer:
A = 2
D = 1
B = 4
C = 3
Step-by-step explanation:
Height of water in bathtub is a function of water in bathtub.
P(t) = w ; t = time ; w = height of water.
A: P (0)=0 ; At time, t = 0 ; height of water = 0, there is no water on bathtub
2: The bathtub starts out with no water.
D: P (20) = 0 ; At time, t = 20 ; w = 0 ;the tub is empty.
1: After 20 minutes, the bathtub is empty.
B:P (4)= 10 `; At t = 4, w = 10 ; height of water in bath tub is 10
4: The height of the water is 10 inches after 4 minutes
C:P (10) = 4 ; At t = 10, w =4, height of water in bathtub = 4 inches
3: After 10 minutes, the height of the water is 4 inches.
