Answer:

Step-by-step explanation:

Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Answer:
C)265
Step-by-step explanation:
To find the median you list all the numbers in order from least to greatest. The number in the middle is the median.
In this case there are two middle number so you have to add them together then devide them by 2.
700, 740, <u>810, 900</u>, 1050, 1120.
810 + 900 = 1,710
1,710/2 = 855.
Your median is 855.
To find the difference you just subtract the two numbers.
1,120-855= 265.
Answer:
(0, 0)
Step-by-step explanation:
The graph of y = tan x passes through the origin, (0, 0).
Answer:
v = ± 
Step-by-step explanation:
Given
E =
( multiply both sides by 2 to clear the fraction )
2E = mv² ( divide both sides by m )
= v² ( take the square root of both sides )
v = ± 
Answer:
Divide your interest rate by the number of payments you'll make in the year (interest rates are expressed annually). ...
Multiply it by the balance of your loan, which for the first payment, will be your whole principal amount.
Step-by-step explanation:
The ending balance, or future value, of an account with simple interest can be calculated using the following formula: Using the prior example of a $1000 account with a 10% rate, after 3 years the balance would be $1300. This can be determined by multiplying the $1000 original balance times [1+(10%)(3)], or times 1.30.
