The equation that is equivalent to the considered equation of log is given by: Option E: 2^3 = x+5

When you raise a number with an exponent, there comes a result.

Lets say you get [tex]a^b = c[/tex]

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

[tex]b = \log_a(c)[/tex]

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

Some properties of logarithm are:

[tex]\log_a(b) = \log_a(c) \implies b = c\\\\\log_a(b) + \log_a(c) = \log_a(b \times c)\\\\\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})\\\\\log_a(b^c) = c \times \log_a(b)\\\\\log_b(b) = 1\\\\\log_a(b) \times log_b(c) = \log_a(c)[/tex]

Log with base e = 2.71828... is written as [tex]\ln(x)[/tex] simply.

Log with base 10 is written as [tex]\log(x)[/tex] simply.

The equation given is:

[tex]\log_3(x+5) = 2[/tex]

By using the definition of log, which says [tex]a^b = c \leftrightarrow \log_a(c) = b[/tex], we get:

[tex](x+5) = 2^3[/tex] or [tex]2^3 = x+5[/tex]

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]

(we used the fact that the question is asked in a way that expresses that there is only one equivalent equation. Plus we used the fact that as option E is a sure equivalent version, so it is correct option).

Thus, the equation that is equivalent to the considered equation of log is given by: Option E: [tex]2^3 = x+5[/tex]

Answer:

40 fluid ounces of drink A must be added to 80 oz of drink B to have a drink whose final proportion of water is 30%

Step-by-step explanation:

35% of 80 oz of drink B = 0.35(80) = 28 oz

0.20(A) + 0.35(80) = 0.30(A + 80)

0.20A + 28 = 0.30A + 24

In Rectangle , 16 copies of ABCD fit inside A'B'C'D'.

What is a rectangle, exactly?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral.

                                       The term "parallelogram" can also be used to describe a rectangle because the opposing sides are equal and parallel.

DA = 3

D'A' = 12

Scale factor DA/D'A' = 3/12 = 1/4

The scale factor = 1/4

The scale factor = 1/4

area ratio = 1/16

Answer:

d = 4

Step-by-step explanation:

If (x -2) is a factor of polynomial p(x), then the remainder will be zero.

$4.70

Step-by-step explanation:

First, you need to divide 18.80 by 8.

18.80/8 = 2.35

2.35 is the unit price for one (1) pound bag of flour,

Multiply by 2 to find the price of a two (2) pound bag.

2.35 * 2 = 4.7

$4.70 is the price of a two-pound bag.

Answer: f= [tex]x^2+4x+8+(7/3x-4)[/tex]

Step-by-step explanation:

Careful with simplifying every step.

Answer:

A: y= 3x-4

B: y= -2/4x+3

Step-by-step explanation:

slope intercept form: y=mx+b

m = slope

slope = rise/run

b = y-intercept

Answer:

A: y = 3x - 4

B: y = -1/2x +3

Step-by-step explanation:

First, lets find the slope of line B. We need to find two coordinates on the line that coincide with points on the grid. We see that (2, 2) and (4, 1) are two points that match the criteria, so we can use both points. You can use any two points, I just randomly chose these two. Slope is nothing but the Y coordinate of the first point  subtracted from the Y coordinate of the second point. We do 2 - 4 and get -2. Next, we do the same thing but with the X coordinates to get 2 - 1, which is 1. We do 1 over -2 to get negative 1/2 for our slope. The last variable in the equation is just where the line hits the Y axis, which is 3. So, the final equation is y = -1/2x + 3. Rinse and repeat for the next question.
