Find the values of a and b such that x2 - 2x + 2 = (x -a) + b LOADS OF POINTS ON THE LINE!!!
Hitman42 [59]

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

Given the diagram below, what is the length of segment EF
bekas [8.4K]
Let x = length of segment EF.

Assume that
(a) line segments AD,  EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.

Then from similarity between geometric shapes, we can write
\frac{2.2}{x} = \frac{x}{4.8}
x^{2} =(2.2)(4.8)=10.56
x=3.2   (nearest tenth)

Answer: B. 3.2

Parvana record's the transactions for her bank account for the week . On Monday, she made a deposit of $45. On Tuesday she used
Andrews [41]

Answer:

The correct answer is +45; -18; -7.

Step-by-step explanation:

Parvana records the transactions for her bank account for the week .

On Monday, Parvana deposited $45. Thus Parvana made an addition of $45 in her account. Therefore a +45 integer is used to represent this transaction into her account.

On Tuesday she used her debit card to $18 for a new shirt. Thus Parvana made a deduction of $18 from her account. Therefore a -18 integer is used to represent this transaction into her account.

On Thursday she withdrew $7 from an ATM. Thus Parvana made a deduction of $7 from her account. Therefore a -7 integer is used to represent this transaction into her account.

Thus the integers +45; -18 and -7 are used to represent transactions in Parwana's account.
