Solve the following equation, using the Bhaskara formula: x² - 5x + 6 = 0

kramer

$x^2-5x+6=0$

$x=\frac{-(-5)\pm\sqrt{(-5)^2-4\times1\times6}}{2\times1}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{25-4\times6}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{25-24}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{1}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm1}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5-1}{2}\;\;\;\vee\;\;\;x=\frac{5+1}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{4}{2}\;\;\;\vee\;\;\;x=\frac{6}{2}\Leftrightarrow$

$\Leftrightarrow x=2\;\;\;\vee\;\;\;x=3$

Answer: $x\in\{2\;;\;3\}$

25. To produce the graph of the function y=0.5cos(0.5x), what transformations should be applied to the graph of the parent funct

soldi70 [24.7K]

Answer:

C. A horizontal stretch to produce a period of $2\pi$ and a vertical compression.

Step-by-step explanation:

We are given the parent function as $y= \cot x$

It is given that, transformations are applied to the parent function in order to obtain the function $y=0.5\cot (0.5x)$ i.e. $y=\frac{1}{2}\cot (\frac{x}{2})$

That is, we see that,

The parent function $y= \cot x$ is stretched horizontally by the factor of $\frac{1}{2}$ which gives the function $y=\cot (\frac{x}{2})$ .

Further, the function is compressed vertically by the factor of $\frac{1}{2}$ which gives the function $y=\frac{1}{2}\cot (\frac{x}{2})$ .

Now, we know,

If a function f(x) has period P, then the function cf(bx) will have period $\frac{P}{|b|}$ .

Since, the period of $y= \cot x$ is $\pi$ , so the period of $y=\frac{1}{2}\cot (\frac{x}{2})$ is $\frac{\pi}{1/2}$ = $2\pi$

Hence, we get option C is correct.

The current, I, varies inversely to the resistance, R. If the current is 250 milliamperes when the resistance is 5 ohms, find th

Arturiano [62]

Answer:

c) 62.5 mA
c) 9 seconds

Step-by-step explanation:

1. resistance is multiplied by 20/5 = 4, so current is multiplied by 1/4.

(1/4)(250 mA) = 62.5 mA . . . . matches choice C

2. distance is multiplied by 144/16 = 9, so time is multiplied by √9 = 3. The time it takes to fall 9 times as far is ...

3 × 3 seconds = 9 seconds . . . . matches choice C
