Answer:
See explanation
Step-by-step explanation:
Assuming the given polynomial is
We then rewrite in decreasing powers of u, to get:
The leading term is
The leading coefficient is the coefficient of the leading term.
The leading coefficient is -7.
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
Vcone=(1/3)hpir^2
Vcylinder=15*pi*5^2=375pi in^3
Vsphere=(4/3)*pi*6^3=288pi in^3
Vcone=(1/3)*15*pi*8^2=320pi in^3
greatest is Vcylinder at 375pi in^3
answer is A (cylinder)
Answer:
A diver can descend 2 feet every minute. If the diver descends for four minutes, where will the diver be in relation to the surface?
Step-by-step explanation:
If the surface is 0 and the diver descends a total of eight feet, then the diver would be at a position of -8 feet.
Hello!
To find the surface area you can divide the prism into the 2D shapes it is made of
First list out all the shapes
2 triangles with bases of 18 and heights of 15.6
3 rectangles with side lengths of 20 and 18
First find the area of the triangles
The equation to find the area of a triangle is
A is area
h is height
b is base
Put in the values you know
Solve
A = 140.4
The triangles have an area of 140.4 units
Next we find the area of a the rectangles
To do this we multiply the sides
18 * 20 = 360
The rectangles have areas of 360 units
Now we add all the areas
There are 2 triangles and 3 rectangles
140.4 + 140.4 + 360 + 360 + 360 = 1360.8
The answer is B) 1360.8cm squared
Hope this helps!
