Think of variable K as number of trees planted and variable J as number of minutes it takes to plant the trees.
K = _J + _
For every 4 trees planted it takes 2 minutes to plant them, so we now have -4/2. 4 is negative because we don't have an unlimited amount of trees to plant. With this being said, we can use this fraction as J.
K = -4/2J + _
We lose 4 trees every 2 minutes, but how many trees did we initially start out with? According to the graph, we started with 28 trees, so K = -4/2J + 28.
Now we can test this equation out by picking a random dot on the graph: 24/2.
24 = -4/2(2) + 28
24 = -4 + 28
24 = 24
This statement is correct, so our equation is correct.
If the result is neither negative nor positive, the simplest option is saying that 0 is neither negative nor positive.
For a number to be subtracted from it's square and equal 0, the only possible number is 1.
1 squared is 1, and 1-1=0.
A=FALSE
B= TRUE (i beleive..not 100% sure)
C= TRUE
D= TRUE( not sure)
<em><u>The surface area of cylinder in standard form is:</u></em>
<em><u>Solution:</u></em>
Given that,
Radius of cylinder = 2x + 3 inches
Height of cylinder = 3 times radius = 3(2x + 3)
Height of cylinder = 6x + 9 inches
<em><u>The surface area of cylinder is given by formula:</u></em>
Where, "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the given values we get,</u></em>
Thus the surface area of cylinder in standard form is found
