Answer:

0.609 / week ( to nearest thousandth)

or you can state it as 60.9% of a book per week

Step-by-step explanation:

That would be 14/23 = 0.609 / week

Select the solution(s) of log2x=1−log(x+4).

mart [117]

Step-by-step explanation:

log2x = 1 - log(x+4)

log2x = log10 - log(x+4)

log2x = log[10/(x+4)]

2x = 10/(x+4)

2x(x+4) = 10

2x² + 8x - 10 = 0

÷2 both sides of equation

x² + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5, 1

x isn't be -5 because logA, A need to be > 0

So, x value is 1

Please answer this correctly.

Ganezh [65]

Answer:

The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.

Step-by-step explanation:

The given function is

$y=2x^2-5$

To find the points which lie on the function, put difference values of x in the given function and find the values of y.

Put x= -2

$y=2(-2)^2-5=2(4)-5=8-5=3$

Put x= -1

$y=2(-1)^2-5=2(1)-5=2-5=-3$

Put x= 0

$y=2(0)^2-5=2(0)-5=-5=-5$

Put x=1

$y=2(1)^2-5=2(1)-5=2-5=-3$

Put x= 2

$y=2(2)^2-5=2(4)-5=8-5=3$

The table of values is shown below.

Plot these points on a coordinate plane and connect them by a free hand curve.

The given function is a nonlinear function because the degree of the function is 2 and we get same value of y for more than one values of x.

How many times greater is The total area of Russia than the total area of Finland? Finland total area is 3.4 x 10 to the 5th pow

Luden [163]

Answer:

The answer to your question is Russia is 50 times greater than Finland.

Step-by-step explanation:

Data

Finland area = 3.4 x 10⁵ km²

Russia area = 1.7 x 10⁷ km²

Proportion = ?

Process

1.- Just divide the Russia's area by the Finland's area.

Proportion = $\frac{Finland's area}{Russia's area}$

Proportion = $\frac{1.7 x 10^{7} }{3.4 x 10^{5} }$

Porportion = 50

If g (x) = 1/x then [g (x+h) - g (x)] /h

lys-0071 [83]

Answer:

$\dfrac{-1}{x(x+h)}, h\ne 0$

Step-by-step explanation:

If $g(x) = \dfrac{1}{x}$ , then $g(x+h) = \dfrac{1}{x+h}$ . It follows that

$\begin{aligned} \\\frac{g(x+h)-g(x)}{h} &= \frac{1}{h} \cdot [g(x+h) - g(x)] \\&= \frac{1}{h} \left( \frac{1}{x+h} - \frac{1}{x} \right)\end{aligned}$

Technically we are done, but some more simplification can be made. We can get a common denominator between 1/(x+h) and 1/x.

$\begin{aligned} \\\frac{g(x+h)-g(x)}{h} &= \frac{1}{h} \left( \frac{1}{x+h} - \frac{1}{x} \right)\\&=\frac{1}{h} \left(\frac{x}{x(x+h)} - \frac{x+h}{x(x+h)} \right) \\ &=\frac{1}{h} \left(\frac{x-(x+h)}{x(x+h)}\right) \\ &=\frac{1}{h} \left(\frac{x-x-h}{x(x+h)}\right) \\ &=\frac{1}{h} \left(\frac{-h}{x(x+h)}\right) \end{aligned}$

Now we can cancel the h in the numerator and denominator under the assumption that h is not 0.

$= \dfrac{-1}{x(x+h)}, h\ne 0$
