15000e^0.0257t = 10000e^0.028t
ln (15000e^0.0257t) = ln (10000e^0.028t)
ln 15000 + ln e^0.0257t = ln 10000 + ln e^0.028t
ln e^0.0257t - ln e^0.028t = ln 10000 - ln 15000
0.0257t (ln e) - 0.028t (ln e) = - 0.4055
- 0.0023t = -0.4055
t = 0.4055 / 0.0023
t = 176.3

15000(2.718282^0.0257)t = 10000(2.718282^0.0287)

Ok now let's begin the work by simplify

15390.496386t = 10291.158134t

Now what ?

Now we have two Ts that give us trouble so we need to eliminate one of them. How ?

We gonna eliminate the one that on the right side by Adding 10291.158134t to both sides.

15390.496386t- 10291.158134t = 10291.158134t-10291.158134t

5099.338252t = 0 (see? we eliminate one of the T)well done:)

T= 0/5099.338252

T= 0

That is the answer for your question Sir.

I hope that's help.. Please rate ↓↓

Answer:

$(x- \frac{2}{5})^{2} = x^2 -\frac{4}{5}x + \frac{4}{25}$

Step-by-step explanation:

You have two methods to expand this binomial.

Method 1

If you have the expression:

$(x- \frac{2}{5})^{2}$

You can write the expression it in the following way:

$(x-\frac{2}{5})^{2}=(x-\frac{2}{5})(x-\frac{2}{5})$

Then, apply the distributive property:

$(x-\frac{2}{5})(x-\frac{2}{5}) = x^2 -\frac{2}{5}x -\frac{2}{5}x+ (\frac{2}{5})\frac{2}{5}$

Simplify the expression:

$(x-\frac{2}{5})^2= x^2 -\frac{4}{5}x+ (\frac{4}{25})$

---------------------------------------------------------------------------------------

Method 2

For any expression of the form:

$(a-b)^2$

Its expanded form will be:

$(a-b)^2= a^2 -2ab + b^2$

$a = x$

$b =\frac{2}{5}$

$(x- \frac{2}{5})^{2} = x^2 - 2x\frac{2}{5} + (\frac{2}{5})^2$

$(x- \frac{2}{5})^{2} = x^2 -\frac{4}{5}x + \frac{4}{25}$

Which of the tables represents a function? Help please i’ll mark brainliest

Helga [31]

Answer:

Table B

Step-by-step explanation:

If you see any number in the input being used more than once, it is not a function. If all numbers of the input are different, it is a function.

Only Table B is a function since all input numbers are different.
