Answer:
(4, - 4 )
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply the original coordinates by the scale factor, that is
(1, - 1 ) → (4(1), 4(- 1)) → (4, - 4 )
Yo sup??
This question can be solved by using the property
a²-b²=(a-b)(a+b)
Here a=A
b=C
plugging in the values
A^2-C^2=(A-C)(A+C)
Hope this helps
Answer:
11/15
Step-by-step explanation:
In this kind of problem, it is cool to always have a value for the total number of students. We can choose any arbitrary value for this. So let’s say the total number of students is 120.
Now we were told 3/5 left for the field trip. The number that left corresponds to 3/5 of 120 = 72 students. The number that didn’t go on the field trip is thus 120 - 72 = 48 students.
Now what do we know again? 1/3 of those who stayed behind didn’t want to go. The number that didn’t want to go is thus 1/3 of 48 = 16. The number that wanted to go but didn’t leave with the first batch is thus 48 - 16 = 32
Now, a bus came along and half of those who wanted to go but were left behind joined. This is equal to a value of 1/2 * 32 = 16
Now the question is what fraction of the class left for the field trip. All we need do is add the first batch to the second batch and divide the result by the total number of students. The addition of both yields = 72 + 16 = 88 students.
The fraction that left was thus 88/120 = 11/15
200/100=2
2*3=6
6=1 month’s interest earnings
6*12=72
72=one year’s interest earnings
200*12=2400
2400=one year’s deposit
72*15=1080
1080=15 year’s interest earnings
2400*15=36000
36000=15 year’s deposit
36000+1080=37080
the answer is $37,080.00
