Answer:
448m^3
Step-by-step explanation:
volume of pyramid = 1/3*area of base * perpendicular height
12*16=192m^2
1/3*192*7=448m^3
Context please, Idk what your asking.
Answer:
100
Step-by-step explanation:
(0.8)(1,000)/(40,000)(0.0002)
800/8
100
The sequence 1, 3, 6, 10, 15, etc find dy/dx...
dy/dx=2,3,4,5 this is not a constant so find d2y/dx2
d2y/dx2=1,1,1, this is a constant, specifically a constant acceleration, which is a property of a quadratic function of the form ax^2+bx+c and if we use three points of the sequence we can solve for all of the variables...
9a+3b+c=6
4a+2b+c=3
a+b+c=1 getting differences
5a+b=3
3a+b=2 and again
2a=1, so a=1/2, making 3a+b=2 become:
1.5+b=2, so b=1/2, making a+b+c=1 become
1/2+1/2+c=1 so c=0 so our function is:
a(n)=(n^2+n)/2
which can be expressed, if you factor the numerator as:
a(n)=n(n-1)/2
4( y-3) +9y is equal to:
Using ditributive property,
4 * y = 4y
4 * 3 = 12
Its equal to:
4y - 12 + 9y
Its also equal to:
9y + 4y = 13y
13y - 12
