If a=0, then the denominator is equal to 0. Since you cannot divide by zero, you are not allowed to do this.
Hope This helps!
Answer:
b
Step-by-step explanation:
Using the trigonometric identity
sin2x = 2sinxcosx
That is the angle on the right side is half the angle on the left, thus
sinΘ = 2sin(
Θ )cos(Θ ) → b
Answer:
You will put 1220.83ft³ of water in the pool
Step-by-step explanation:
radius = half of diameter
d = 18ft
r = 18ft / 2 = 9ft
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 6ft
π = 3.14
r = radius = 9ft
v = (π * r²) * h
we replace with the known values
v = (3.14 * (9ft)²) * 6ft
v = (3.14 * 81ft²) * 6ft
v = 254.34ft² * 6ft
v = 1526.04ft³
The volume of the cylinder is 1526.04ft³
If it is filled to 80% then we have to multiply the volume by 80/100
1526.04ft³ * 80/100 = 1220.83ft³
You will put 1220.83ft³ of water in the pool
Answer:
58.66 is the radius of the circle
Answer:
Cos x = 
Tan x = 
Step-by-step explanation:
Sin x = 
So, Perp = 1 and hyp = 2
<em>Putting this in Pythagorean theorem to get the base</em>
base ² = 4-1
base² = 3
<em>Taking square root on both sides</em>
Base = 
Now
Cos x =
Tan x =
