Answer:
sin(2*36.86989765) and get .96 or 24/25
7/25
Step-by-step explanation:
Start by solving for P
sinP=3/5
take the arcsin or sin^-1 and get
p=36.86989765
Then multiply by 2 and take the sin and get
sin(2*36.86989765) and get .96 or 24/25
Then take cos(2*36.86989765)=.28 or 7/25
Answer:
1. a^3/6 (15)^{1/2}
2.
a. a = 12 cm
b. V = 384 cm^3
Step-by-step explanation:
1. The volume of rectangular pyramid is given by:
b: base area = a^2
h: height
c: side edge = 2a
"h" can be calculated by using the Pitagora's theorem:
The, the volume is:
2.
a. The side base is calculated by using the Pitagora's theorem again:
b. The volume is given by:
I think it’s the second answer but just look at the inequality
Answer 9
The first value behind the decimal point is 0.
When rounding if the value is 0-4 then the value you are rounding to remains the same.
If the value is 5-9 then the value would round up.
However, because it is a 0 it remains a 9.
Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
