Midpoint
x = (x1 + x2)/2
y = (y1 + y2)/2
19)
x = (x1 + x2)/2 = (5 + 4 )/2 = 4.5
y = y = (y1 + y2)/2 = (-6 + 3)/ 2 = -3/2= -1.5
Answer: Midpoint (4.5, -1.5)
20)
x = (x1 + x2)/2 = (-3 -2 )/2 = -2.5
y = y = (y1 + y2)/2 = (7 + 5)/ 2 = 6
Answer: Midpoint (-2.5, 6)
21)
x = (x1 + x2)/2 = (-2 + 8 )/2 = 3
y = y = (y1 + y2)/2 = (9 + 0)/ 2 = 4.5
Answer: Midpoint (3, 4.5)
22)
x = (x1 + x2)/2 = (-4 - 13/2 )/2 = -5.25
y = y = (y1 + y2)/2 = (1 - 6 )/ 2 = -2.5
Answer: Midpoint (-5.25, -2.5)
Answer:
just saying I'm hosting a google meet if you wanna join lol
13.7 is 100% I like to divide by 100 to get the 1%, then multiply by the percent i am trying to find, lets see if I'm right.
13.7/10 = .137
.137= 1/100
.137 x 160 = 21.92
Your answer is 21.92, 21.92 is 160%
Hope this helped!
Answer:
A, B and D are true statements.
Step-by-step explanation:
We are given a binomial expansion
Now we will check each option
Option A: The coefficients of 
and 
both equal 1.
If we see first and last term of the expansion, This statement is true.
Option B: For any term 
in the expansion, a + b = n.
Let we take 3rd term of expansion 
Here, a=n-2 and b=2
If we do a+b = n-2+2=n
a+b=n is true statement.
Option C: For any term x^ay^b in the expansion, a - b = n.
Let we take 3rd term of expansion
Here, a=n-2 and b=2
If we do a-b = n-2-2=n-4≠n
a-b=n is false statement.
Option D: The coefficients of x^ay^b and x^by^a are equal.
If we take second term from beginning and last of the expansion.
This statement true.
1/12c = 0.6
To remove a fraction you simply multiply it by its inverse fraction (take the original fraction and flip it! So, multiply it by 12/1 (which is the same as saying 12).
12(1/12c) = 0.6*12
The 12 cancels out leaving this:
c = 0.6 * 12
c = 7.2
If you don't have or are allowed to use a calculator. To compute that you simply make 0.6 into a fraction then multiply the numerator by 12. .6 is in the tenths place so you can write it like this:
6/10 simplifying it becomes, 3/5
3/5 * 12 = 36/5
Now! That was assuming 1/12c was written like this:
(1/12)c = 0.6
If it was actually written like this:
1/(12c) = 0.6 then you'll do this.
Multiply 0.6 by 12c. Which will get you 7.2c. After that you need to get c alone, so you divide both sides by 7.2. Yielding the result:
1/7.2 = c
c = 0.1389...
