Answer:
V = 3163.52 cubic foot
Step-by-step explanation:
The formula for volume of a right circular cone
v = πr^2 h/3
V = volume of the cone
π = pie
r = radius of the cone
h = height of the cone
We are provided with
Radius = 16ft
Height = 11.8ft
π - 22/7
Inserting the values
V = πr^2h/3
V = 22/7 * 16^2 * 11.8/3
V = 3.142 * 256 * 3.933
V = 3163.516416
According to the question, we are asked to round off to nearest tenth cubic foot
V = 3163.52 cubic foot
(X+Y+Z)/3=84 X,Y,Z IS THE THREE UNKNOWN SCORES.TO KNOW THE TOTAL , MULTIPLY THE 84 BY 3.
84*3=252
(252+H)/4=87 H IS THE FOURTH GRADE HE SHOULD HE IF HE WANTS HIS AVERAGE TO BE 87
87*4=348
252+H=348
H=348-252
H=96
Answer: 
Step-by-step explanation:
Given: u and v be are the solutions of 
Let 
is the quadratic equation and u and v are the zeroes/solutions then
Sum of zeroes; 
Product of zeroes; 
Comparing to
we get a= 3 , b= 5 and c = 7
Now we have to find
adding and subtracting 2uv in numerator we get
Substituting the values from (i) and (ii) we get
Hence, the value of 
is
So hmm check the picture below
and since you already covered solving system of equations, surely you'll breeze right through B)
W is the X axis so as the X goes back to the origin, the line, H(w) gets larger.
