Answer:
Step-by-step explanation:
if cot=3/4 and the terminal point determined by is in quadrant 3, then ... cos ((3\pi )/(4)) ... The angle of elevation to the top of a 20-story skyscraper is measured to be 2 ... If the point P(-4/5,y) lies on the unit circle and P is in the third quadrant, what does y equal ...... if z1=5+5i and z2=8(cos(3pi/7)+isin(3pi/7)) then z1 z2=____?
Answer:
33.49cm³
Step-by-step explanation:
Volume of sphere =4/3πr³
diameter = 4cm
radius = diameter/2 = 4/2 = 2
Volume of sphere =4/3πr³= 4/3 x 3.14 x 2³ = 4/3 x 3.14 x 8 = 4/3 x 25.12 = 4x25.12/3 = 100.48/3 = 33.49cm³
Move all terms to the left side and set equal to zero. then set each factor equal to zero .
x = - 6 - y
______
4 + r
Answer:
C
Step-by-step explanation:
-0.2(x-20)=44-x
Divide both sides by -0.2:
x-20=-220+5x
Subtract x from both sides:
-20=-220+4x
Add 220 to both sides:
200=4x
x=50, or answer choice C. Hope this helps!
There are a lot of questions and work here, I can help you get started in the right direction.
On the left, you have the heights for Soil A. On the right, you have the height for Soil B. Looking at the overlap, there are a lot of heights in the 60's and 70's for both.
To calculate the mean, add up all the values and divide by the total.
For the MAD, you have to subtract each value from the mean. Then, take the absolute value of it. Finally, find the mean of those values.
The one with the higher MAD is more variable.
