Which of the following rotations will produce a 12-sided polyhedron? ANSWERS: Rotating a 12-gon about a vertical axis running along one side Rotating a 12-gon about a vertical axis passing through the center No rotation will produce a polyhedron. The solids of rotation are non-polyhedral. Rotating a 12-gon about a horizontal axis passing through the center

Answers

Answer 1

Answer:

Answer:

No rotation will produce a polyhedron. The solids of rotation are non-polyhedral.

Step-by-step explanation:

Solids of rotation will always have a curved face, so they’re always non-polyhedral.

PLS HELPPPP Write a linear equation in point slope form for the line that goes through (-1,3) and (1,-9) 15 pts

Answers

Solution:

First find the slope

$Slope=(y2-y1)/(x2-x1)\nSlope=((-9)-(3))/((1)-(-1))\nSlope = (-12)/(2)\nSlope=-6\n$

Secondly, write the equation

$y=m(x-xo)+yo\ny=-6(x-1)+(-9)\ny=-6x+6-9\ny=-6x-3$

Answer:

$y=-6x-3$

Check:

$(-1,3)\ny=-6(-1)-3\ny=6-3\ny=3$

$(1,-9)\ny=-6(1)-3\ny=-6-3\ny=-9$

What is 3/5 of 6,000

Answers

we have to find what is 3/5 of 6000
so basically of means in mathematically multiply.. ( of = multiply )
So now let's solve the problem
$(3)/(5)$ of 6000
i.e $(3)/(5)$ * 6000
= 3 * 1200
= 3600

So your correct answer is 3600

Hope this helped you :)

for this question the only thing you should do is to multiply 3/5 by 6000 so you will have:
3/5 * 6000 = 3,600 :)))
i hope this is helpful
have a nice day

Calvin and Mike do sit-ups when they work out. They start with 64 sit-ups for the first set and do half as many each subsequent set. A. What representation can you use to show the relationship between the set number and the number of sit-ups?

Answers

To represent the relationship between the set number and the number of sit-ups, you can use a simple verbal description: "The number of sit-ups in each set is half of the number in the previous set". The relationship between the set number and the number of sit-ups can be represented as a geometric sequence, where each set has half the number of sit-ups as the previous set. This can be calculated using the formula for a geometric sequence.

To represent the relationship between the set number and the number of sit-ups that Calvin and Mike do, you can use a mathematical expression or formula. In this case, the number of sit-ups in each set decreases by half compared to the previous set. You can express this relationship using an exponential decay formula:

$S_(n) = S_(1) . ((1)/(2)) ^(1-n)$

Where:

$S_(n)$ represents the number of sit-ups in the nth set.

$S_(1)$ is the initial number of sit-ups in the first set (which is 64 in this case).

$(1)/(2)$ represents the reduction factor, as each subsequent set has half as many sit-ups.

n is the set number.

Using this formula, you can easily calculate the number of sit-ups in any set. For example, to find the number of sit-ups in the 4th set (n = 4), you would substitute n = 4 into the formula:

$S_(4) = 64 . ((1)/(2)) ^(4-1) = 64.((1)/(2)) ^(3) = 64 .(1)/(8) =8$

So, in the 4th set, Calvin and Mike do 8 sit-ups. This formula allows you to determine the number of sit-ups for any set without manually calculating each time.

alice baked a certain number of pies. she gave 1/8 of the pies to her friends and 1/4 of the remainder to her neighbor. she was left with 63 pies. how many pies did alice bake at first?

Answers

if she was left with 63 then you do 63 divided by 3 times 4 which is 21 times 4
so u get 84
then u do
84 divided by 7
which is 12
and multiply by 8
which is 96

Answer: if she was left with 63 then you do 63 divided by 3 times 4 which is 21 times 4

so u get 84

then u do

84 divided by 7

which is 12

and multiply by 8

which is 96
