Use differentials to estimate the amount of material in a closed cylindrical can that is 60 cm high and 24 cm in diameter if the metal in the top and bottom is 0.1 cm thick, and the metal in the sides is 0.05 cm thick. Note, you are approximating the volume of metal which makes up the can (i.e. melt the can into a blob and measure its volume), not the volume it encloses. The differential for the volume is
Answer:
dV ≈ 927.4 cm³
Step-by-step explanation:
Formula for volume of a cylinder is;
V = πr²h
Using differentials, we have;
dV = (dV/dr)dr + (dV/dh)dh
Now, dV/dr = 2πrh
dV/dh = πr²
Thus, at r = 24/2 = 12 cm
And at h = 60 cm, we have;
dV/dr = 2π(12 × 60)
dV/dr = 4523.89 cm²
Also;
dV/dh = π(12)²
dV/dh = 452.39 cm²
the metal in the top and bottom is 0.1 cm thick. Thus, dr = 2 × 0.1 = 0.2
the metal in the sides is 0.05 cm thick. Thus; dh = 0.05
Thus;
dV = (4523.89 × 0.2) + (452.39 × 0.05)
dV ≈ 927.4 cm³
Find the perimeter of the figure.
Answer:
Well I’m not sure what you want but I’ll give you both,
The perimeter is 25 units
The area is 28.5 units ^2
Step-by-step explanation:
Well to find perimeter just count every unit which is what I did and got 25 units.
To find the area jsut split them into two shapes and find the area for both.
Triangle formula: bh/2
Rectangle: Lw
Well we have 3 for base and 3 for height.
3*3=9
9/2=4.5
4.5 is the triangle
We got 3 for width and 8 for length
3*8=24
24 is the rectangle
Add them up
24+4.5= 28.5
28.5 units

28.5?

Questions:
1. Write the fitted regression equation (30 points).
2. Write the estimated intercepts and slopes, associated with their corresponding standard errors (30 points).
3. Interpret each coefficient (40 points).
Answer:
Kindly check explanation
Step-by-step explanation:
Given the summary output :
_______ Coeff___ StdError__ t-stat
Intercept 1283.000_ 352.000 _ 3.65
X1 _____ 25.228 ____8.631
X2 _____0.861 _____0.372
General form of a multiple regression model:
Y = B1X1+B2X2 +E
The fitted regression equation is :
y = 25.228X1 + 0.861X2 + 1283
Intercept and slope corresponding to the standard error :
Intercept = 352
Slope 1 = 8.61 ; slope 2 = 0.372
'B' coefficient represents the change in the mean response, Y, per unit increase in a version predictor variable when all the other predictors are held constant.
B1 represents the change in the mean response, U, per unit increase in x1 when x2, x3, ..., xk are held constant
B2 represents the change in the mean response, U, per unit increase in x2 when x1, x3, ..., xk are held constant

I need help with Algebra 2. Thank you! :)
Answer:
B: 6.0
Step-by-step explanation:
-3t^2+9t+54 = 0
This is the equation that needs to be solved
Divide both sides by -3
t^2 - 3t - 18 = 0
The factors of 18 are: (1 18) (2 9) (3 6)
3 - 6 = -3 and 3 x -6 = -18
So: (t + 3) (t - 6) = 0
t = -3, 6
It can't be negative so the answer is 6

A shelf is built on a wall, as shown below. What is the value of x?
(2x+1) + (3x-1)
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.
Nick is making bread.
He needs 103 cups of flour to make one whole loaf of bread.
He has 53 cups of flour.
Use the drop-down menus to complete the statements below about the bread that Nick can make.
Answer:
Well, I can't see the drop-down options but with that amount of flour, I suppose he could make one half of a loaf but he can't make an entire loaf.
Edit:
The answers for the drop-down options:
1.) Nick can make less than one whole loaf of bread.
2.) Nick can make exactly 1/2 loaf of bread with the flour he has.

Step-by-step explanation:
The exact quotient is 876.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
21,900 / 25

What is angle LKM? I need help right away please!!
Answer:
Angle LKM is 110
Step-by-step explanation:
Since all the angles in a triangle equal 180, and 60 is one angle you can see its an equilaterial triangle.
so x=60
Then 3(60)-70=110
So LKM=110
Answer:
125, i don't know if I'm right though so try it? :)
Step-by-step explanation:
Well an exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of exterior angle and interior angle is equal to 180 degrees
180-60=120
120=x+(180-(3x-70))
x=65
3*65=195
