Answer:
Step-by-step explanation:
Factorize using square root method.
x² - 2x + 2 = (x-a)² + b
x² -2x + 1 + 1 = (x-a)²+b
(x² - 2*x*1 + 1²) + 1 = (x -a)²+ b {Compare with a²- 2ab+b² which is (a - b)²}
(x - 1)² + 1 = (x - a)² + b
a = 1 and b = 1
Answer:
a) 3.375 cents
b) 26 Apples
Step-by-step explanation:
a) Each apple costs .1875 cents, multiply .1875 by 18 to get the cost of 18 apples
b) divide 5 by .1875 to get your 26.6666667 Apples, which would round down because you can't have .6666667 of an apple
OK so where is the weekly math homework!?
Answer:

Step-by-step explanation:
The formula for distance is:

Where (x₁, y) and (x₂, y₂) are the points.
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:
- x₁= -6
- y₁ = 6
- x₂ = -3
- y₂ = 3
Substitute the values into the formula.

Solve inside the parentheses.
- -3 --6 = -3+6 = 3
- 3-6 = -3

Solve the exponents.
- (3)²= 3*3= 9
- (-3)²= -3*-3 =9

Add.


Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.

The distance between the two points is apprximately <u>4.2</u>
