What logarithmic function represents the data in the table?.

baherus [9]

x | f(x)
25 | 2
125 | 3
625 | 4

From my research, the above table belongs to the question. The values in x show increasing exponential values of 5, where:

5^2 = 25
5^3 = 125
5^4 = 625

As for the case of f(x), they are the values of the powers. So the logarithmic function that would explain the values of x and f(x) would be:

A base-5 function:
f(x) = log5 x

Caroline, Krutika and Natasha share some sweets in the ratio 4:3:3. Caroline gets 9 more sweets than Natasha. How many sweets do

vagabundo [1.1K]

Answer:

Krutika gets 27 sweets

Step-by-step explanation:

Let

x ---> number of sweets that Caroline gets

y ---> number of sweets that Krutika gets

z ---> number of sweets that Natasha gets

we know that

$x:y:z=4:3:3$

$\frac{x}{y}=\frac{4}{3}$

$x=\frac{4}{3}y$ ----> equation A

$\frac{x}{z}=\frac{4}{3}$

$x=\frac{4}{3}z$ ----> equation B

$y=z$ ---> equation C

Caroline gets 9 more sweets than Natasha

$x=z+9$ ---> equation D

substitute equation D in equation B

$z+9=\frac{4}{3}z$

solve for z

$\frac{4}{3}z-z=9$

$\frac{1}{3}z=9\\z=27\ sweets$

therefore

Krutika gets 27 sweets

Here is a graph of the function y, both continuous and differentiable. For approximately what values of x between -5 and 5 is th

Law Incorporation [45]

From the graph you can determine the first derivative by looking at the turning points. These are where the first derivative is zero.

$y' = x(x-2)(x+2)(x-5)(x+5) \\ \\ y' = x^5 -29x^3 +100x$

Take derivative to get 2nd derivative and set equal to zero:
$y'' = 5x^4 -87x^2 +100 = 0$

Solve for x:
$x^2 = \frac{87 \pm \sqrt{87^2 -2000}}{10} \\ \\ x = \pm 1.11, \pm 4.02$
