Answer:
A
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the base radius and h the height )
Here r = 6 and h = 8, then
V = π × 6² × 8 = π × 36 × 8 = 288π cm³ → A
The partition point is (-7/2, 23/4)
<h3>How to determine the
partition point?</h3>
The given parameters are:
(x1,y1) = (-6,-1)
(x2,y2) = (4,8)
a = 1 and b = 3
The partition point is calculated as:
(x, y) = ((bx1 + ax2)/(a + b) ,( by1+ay2)/a+b)
So, we have:
(x, y) = ((3 * -6 + 1 * 4)/(1 + 3) ,(3 * 8 + 1 * -1)/1+3)
Evaluate
(x, y) = (-14/4, 23/4)
Simplify
(x, y) = (-7/2, 23/4)
Hence, the partition point is (-7/2, 23/4)

Answer:
Model used is
Step-by-step explanation:
To find the product of 0.8x0.6 using the known identities
We find that both numbers are near to 1.
Hence x can be taken as 1
We know that
can be used here making x = 1 and a =-0.2 and b=-0.4
The product becomes
THus we find easily using the mdoel that answer is 0.48
F(x) = (x + 1)(x - 2)
f(x) = x(x - 2) + 1(x - 2)
f(x) = x(x) - x(2) + 1(x) - 1(2)
f(x) = x² - 2x + x - 2
f(x) = x² - x - 2
