Answer:
1a - reduction
2a- enlargement
3a- reduction
4a- enlargement
Step-by-step explanation:
when the scale factor is greater than 100% it is making it larger, when less than 100% size it is making it smaller. for every answer do the original number (ex #1 would be 48 inches) and multiply it by the scale factor in decimal form, by moving the decimal over two places (ex #1 the 25% would become .25 or 1/4). therefore #1 would be an equation like 48 x 0.25= 12
For every 2 days the weight increases by 60 grams. So for just one day you would half it and get 30 grams. So on day 4 if it is 365 grams you would add 30 grams to get 395 grams.
Therefore the answer would be D
Hope this helps! :)
I don't know if I am correct or not, but I believe that you have to multiply the perimeter of your base and then multiply that by the height of your cube.
So in this case, you would do 4 x 4, since a cube is basically 6 squares, and a square has 4 sides.
4 x 4 = 16
Then the height is 4 as well.
16 x 4 = 64² (I believe you have to square the total as well, so don't forget that.)
If I am incorrect, please let me know. But I really do hope this helped. :)
<h2>
The all roots are equation are 1, - 1 and - 2.</h2>
Step-by-step explanation:
The given cubic polynomial:
k(x) = 
+ 2
- x -2
To find, the all roots are + 2 - x -2 = ?
∴ k(x) = + 2 - x -2
⇒ + 2 - x -2 = 0
⇒ (x + 2) - 1(x + 2) = 0
⇒ ( - 1)(x + 2) = 0
⇒ - 1 = 0 and x + 2 = 0
⇒ - 1 = 0
⇒ = 1
⇒ x = ± 1 = 1, - 1
or, x + 2 = 0
⇒ x = - 2
Thus, the all roots are equation are 1, - 1 and - 2.
Find the total ways that people can be seated with no restrictions;
6! ways but you know that marcia and jan will not sit together.
Write out this, as: G, (M, J), B, P <-- M and J (Marcia and Jan are grouped together to find the ways they will be sat together, so we can subtract this away).
In this combination, considering M and J as one, you have 5! ways. Then you see that M and J can switch position, so there would be added 2! ways.
In total, possibility of J and M to sit together is 5!2!
6!-5!2!
=720-240
= 480 possible ways of seating the friends so that Jan and Marcia are not together.
Hope I helped :)
