The answer is 56 percent black pens
Answer:
If you mean: y =(lnx)
3
then:
dy
/dx = [3(lnx)
Step-by-step explanation:
First from the information we have, we see that the volume of the cube is 27cm3. So what are the dimensions of its length, width and height? This information will help us to determine the dimensions of the square pyramid.
Volume of a cube is found from the formula V = a3
Where V is volume, and a is the length of one side.
We expand this equation to be:
V= a * a * a
Since all sides of a cube are equal, then this equation will be:
27 = 3 * 3 * 3
Now we know the length width and height of the cube.
Volume of a square pyramid is given by the formula V =1/3ah
Where V is the volume, a is the area of the base of the pyramid, h is the height of the pyramid.
Since it fits perfectly into the cube, then its dimensions are the same as the cube, so:
Area of the base is Length * Width so:
a = 3 * 3 = 9
and height:
h = 3
Now therefore:
V = 1/3 * 9 * 3
V = 1/3 * 27
V = 27/3
V = 9 cm3

Answer:
y = -x + 1
Step-by-step explanation:
you know that it must be y = mx + b form so you know that b is the y-intercept and the only time it touches is on positive one so you know it needs a positive one. then to find the slope you need to use the two points that are given. Rise/Run(rise over run) it only goes up one and over -1 so divide and you get -1 for the slope.
hope this helps!
Answer: If Gregg colored none of the numbers blue, then obviously the chance the of his coloring being factorific would be zero.
If Gregg colored all of his cards blue, then again the chance would be 100%. This is because at least one of the cards is blue and all the divisors are blue.
On the other hand if only some of the cards are blue, then are numerous possibilities for the probability. You would have to create a chart and analyze each option to make sure the divisors were also blue.
