Using the completing-the-square method, rewrite f(x) = x2 - 6x + 2 in vertex form.<br>​
sp2606 [1]

Answer:

\large\boxed{f(x)+(x-3)^2-7}

Step-by-step explanation:

\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\\\\f(x)=x^2-6x+2=x^2-2(x)(3)+1=x^2-2(x)(3)+3^2-3^2+2\\\\\text{Use}\ (a-b)^2=a^2-2ab+b^2\to x^2-2(x)(3)+3^2=(x-3)^2\\\\f(x)=(x-3)^2-9+2=(x-3)^2-7

1. Find the distance from point P to QS
12345 [234]

Answer:

5.7 units

Step-by-step explanation:

The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).

Use distance formula to calculate distance between P and R:

PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

P (1, 1) = (x_1, y_1)

R(-3, 5) = (x_2, y_2)

Plug in the values into the formula.

PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2}

PR = \sqrt{(-4)^2 + (4)^2}

PR = \sqrt{16 + 16}

PR = \sqrt{32}

PR = 5.7 units (to nearest tenth)

An investment made in the stock market decreased at a rate of 1.2% per year for 25 years. What is the current value of the $100,
densk [106]

Use A = P (1 + r/n) ^(nt). Assuming that we're dealing with years here, n = 1, so we have


A = P (1 + r) ^(t), where r is the interest rate as a decimal fraction.


The investment decreases in value, so the common ratio r is (1.000-0.012), or 0.988.


Thus, A = $100,000* (0.988) ^25 = $73947.52 is the current value, after 25 years.
