Approximately 1.9 grams per cubic centimeter.
First you calculate the size of the cylinder in centimeters by taking the area of the base and multiplying it by the height, and then you divide the mass of the cylinder by the volume.
Given
f(x) = −5x9 − x8 + 3x3 − 8
and
g(x) = −5x9 − 5x3 − 5x2 + 5,
find and simplify

X+5 Y-6 means that the figure is
Answer:
The figure is translating right 5 and down 6
Step-by-step explanation:
X and Y both represent axis on a coordinate grid. x+5 simply means adding 5 to a value. In other words, on a coordinate grid, an increase in the value means you are going right, the lower the farther left. Same for the y axis, the higher the more you are increasing vertically, the lower the value the lower the point is.

Suppose you roll a fair die. Let X be the value of the roll. What is the Moment Generating Function of X?
Answer:
μ₁`= 1/6
μ₂= 5/36
Step-by-step explanation:
The rolling of a fair die is described by the binomial distribution, as the
the probability of success remains constant for all trials, p.the successive trials are all independent the experiment is repeated a fixed number of times there are two outcomes success, p, and failure ,q.The moment generating function of the binomial distribution is derived as below
M₀(t) = E (e^tx)
= ∑ (e^tx) (nCx)pˣ (q^n-x)
= ∑ (e^tx) (nCx)(pe^t)ˣ (q^n-x)
= (q+pe^t)^n
the expansion of the binomial is purely algebraic and needs not to be interpreted in terms of probabilities.
We get the moments by differentiating the M₀(t) once, twice with respect to t and putting t= 0
μ₁`= E (x) = [ d/dt (q+pe^t)^n] t= 0
= np
μ₂`= E (x)² =[ d²/dt² (q+pe^t)^n] t= 0
= np +n(n-1)p²
μ₂=μ₂`-μ₁` =npq
in similar way the higher moments are obtained.
μ₁`=1(1/6)= 1/6
μ₂= 1(1/6)5/6
= 5/36

A substance with a half life is decaying exponentially. If there are initially 12grams of the substance and after 70 minutes there are 7 grams, after how many minutes will there be 2 grams remaining?
Answer:
Step-by-step explanation:
Use the half life formula
[tex]N=N_0e^{kt}[/tex] where N is the amount after decay, No is the initial amount, e is Euler's number, k is the decay constant, and t is the time in minutes. For us, the first equation looks like this:
[tex]7=12e^{k(70)}[/tex] and we will solve that for k and then use that value of k in the second equation to find time.
Begin by dividing 7 by 12 to get
[tex]\frac{7}{12}=e^{k(70)}[/tex] Now take the natural log of both sides since the natural log and that e are inverses. The e then disappears:
[tex]ln(\frac{7}{12})=k(70)[/tex]
Plug the left side into your calculator and then set it equal to the right side, giving us:
[tex]-.5389965007=70k[/tex]
Divide both sides by 70 to get the k value of
k = -.00769995
Now the second equation looks like this:
[tex]2=12e^{(-.00769995)t[/tex] where t is our only unknown now that we know k.
Begin by dividing both sides by 12 to get
[tex]\frac{1}{6}=e^{-.00769995t[/tex] and take the natural log of both sides again to eliminate the e:
[tex]ln(\frac{1}{6})=-.00769995t[/tex]
Take care of the left side on your calculator to get
-1.791759469 = -.00769995t and divide both sides by -.00769995 to get
t = 232.697 minutes

A child fills a bucket with sand so that the bucket and sand together weigh 10 lbs, lifts it 2 feet up and then walks along the beach, holding the bucket at a constant height of 2 ft above the ground. How much work is done on the bucket after the child has walked 100 ft?
Total weight, w = 10 lbs.
Height of the bucket, h = 2 feet.
Distance walked, d = 100 ft.
Now, work done in moving the bucket at a height of 2 feet.
W = mgh
W = 2× 32.17×100
W = 6434 lbs ft²/s²
Work done in moving bucket in horizontal direction is zero because it is perpendicular to the force.
Therefore, work done is 6434 lbs ft²/s² .
Hence, this is the required solution.

Answer:
So now D would be at (-4 , 2)
Step-by-step explanation:
From D, you can calculate every other letter’s location. Yeah.
Answer:
Please mark me as brainliest!
Step-by-step explanation:
The coordinates:
D: ( 2,6 )
A: ( 2, 1 )
B: ( 5, 1 )
C: ( 5, 6 )
You want to translate this down 4 units and left 6 units.
So what you would do is this:
Formula = ( x - 6 , y - 4 )
D: ( -4, 2 )
A: ( -4, -3 )
B: ( -1, -3 )
C: ( -1, 2 )

Answer:
Horizontal component = 9.6
Step-by-step explanation:
Recall that the horizontal component is given by the cosine projection;
[tex]v_x=|v_0| * cos(\theta)[/tex]
which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:
[tex]v_x=12.6 * cos(40.5^o)=9.5811[/tex]
And rounding to the nearest tenth as requested, we have:
[tex]v_x=9.6[/tex]
Find an equation of the plane that passes through the point (1, 3, 4) and cuts off the smallest volume in the first octant.
Answer:
12x +4y + 3z=36
Step-by-step explanation:
The equation of plane is given by
z-zo = a(x-xo) + b(y-yo)
pass through (1,3,4)
Z -4 = a(x -1) +b(y-3)
The question is asking us to optimize a and b. To minimize the volume V both a and b should be negative as the normal vector should be towards the negative x and y direction so that a finite tetrahedron can be formed in the first octant.
we need x , y and z intercepts o define volume
x intercept( y, z =0) = [tex]\frac{a+3b-4}{a}[/tex]
y intercept (x, z =0) = [tex]\frac{a+3b-4}{b}[/tex]
z intercept ( x, y =0) = -(a+3b-4)
Base = [tex]\frac{(a+3b-4)^2}{2ab}[/tex]
Volume = [tex]\frac{1}{3}*base*height[/tex]
Volume(a, b) = [tex]\frac{-(a+3b-4)^3}{6ab}[/tex]
now we differentiate partially in terms to a and b the volume to minimize and get a and b.
ΔV(a, b) = [tex]\frac{-1}{6}(\frac{3(a+3b-4)^2ab-b(a+3b-4)^3}{a^2b^2}[/tex] ,[tex]\frac{-1}{6}(\frac{9(a+3b-4)^2ab-a(a+3b-4)^3}{a^2b^2}[/tex] = 0
Taking the first part of differential it will give
b(a+3b-4) [3a -(a+3b -4)] =0
(a+3b-4) [tex]\neq 0[/tex] because the volume will become zero if this becomes true
2a -3b = -4 ..................(1)
similarly the second part of the differential will give
a-6b=4 ................(2)
on solving 1 and 2 we get
a = -4 and b = -4/3
so the equation will be
Z -4 = -4(x -1) - 4/3*(y-3)
final equation
12x +4y + 3z=36
Jenny makes food for her hummingbird feeders
the sum of 5th and 9th terms of AP is 72 and the sum of 7th and 12th term is 97 find AP
Answer:
The AP is 6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61 ....
Step-by-step explanation:
The nth term = a1 + d(n - 1)
Sum of 5th and 9th terms
= a1 + 4d + a1 + 8d = 72
2a1 + 12d = 72.............(1)
Similarly:
a1 + 6d + a1 + 11d = 97
2a1 + 17d = 97..............(2)
Subtracting equation (1) from equation (2):
5d = 25
d = 5.
and , using equation (1), the first term
a1 = (72 - 12(5)) / 2
= 12/2
= 6.
