Answer:

6^2

Step-by-step explanation:

It is written as a division problem. When dividing exponents with the same base you subtract the exponents. in this class, 7-5=2. So now you write the new exponent:

$6 ^{2}$

The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the cor

vredina [299]

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is option C.

Answer:

x(log(x) - 1) + C

Step-by-step explanation:

The formula for the derivative of a logarithm function is:

$\frac{d}{dx} log_{a}(x) = \frac{1}{xlog(a)}$

For your case, the base is 10. Now that we have the derivative, lets use integration by parts. I will be differentiating log(x) and integrating 1:

u = log(x)

du = dx/xlog(10)

dv = 1

v = x

You get:

log(x)x - integral(dx/log(10))

Therefore the answer is:

log(x)x - x/log(10) + C

x(log(x) - 1) + C

Answer:

you are unwilling to predict the proportion value at your school = 0.90

b)

The large sample size 'n' = 864

Step-by-step explanation:

Given estimated proportion 'p' = 10% = 0.10

Given Margin of error M.E = 0.02

Level of significance α = 0.05

you are unwilling to predict the proportion value at your school

q = 1- p = 1- 0.10 =0.90

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} } \sqrt{p(1-p)} }{\sqrt{n} }$

$0.02 = \frac{1.96 X \sqrt{0.10 (0.90)} }{\sqrt{n} }$

Cross multiplication , we get

$\sqrt{n} = \frac{1.96 X \sqrt{0.10 (0.90)} }{0.02 }$

√n = 29.4

Squaring on both sides , we get

n = 864.36

Conclusion:-

The large sample size 'n' = 864

If alpha and beta are the roots of a quadratic polynomial 3x^2-6x-1 find the values of (Alpha-beta)

Murrr4er [49]

Answer:

Either $-4\sqrt{6}$ or $4\sqrt{6}$ , depending on whether $\alpha$ is larger than $\beta$ .

Step-by-step explanation:

The two roots (might necessarily be distinct or real) of the quadratic equation

$ax^{2} + bx + c = 0$ , where $a$ , $b$ , and $c$ are constants and $a\ne 0$ are

$\displaystyle x_1 = \frac{-b+\sqrt{\text{b^{2} - 4ac}}}{2a}$ , and
$\displaystyle x_2 = \frac{-b-\sqrt{\text{b^{2} - 4ac}}}{2a}$ .

The difference between the two will be either:

$x_1 - x_2 = 2\sqrt{b^{2} - 4ac}$ or

$x_2 - x_1 = -2\sqrt{b^{2} - 4ac}$ .

For this question,

$a = 3$ ,
$b = -6$ , and
$c = -1$ .

$x_1 - x_2 = 2\sqrt{(-6)^{2} - 4\times 3\times (-1)} = 4\sqrt{6}$ , or

$x_1 - x_2 = -2\sqrt{(-6)^{2} - 4\times 3\times (-1)} = -4\sqrt{6}$ .
