6^5x=20 round to the nearest ten-thousands
natulia [17]
Ok so 6^5
6x6x6x6x6 = 7776

7776x=20

Then we divide each side by 7776

7776x = 20
——— ———
7776 7776


X= 0.00257202

If f(x)=4arctan(7x), find f'(x). Find f'(4).
Pachacha [2.7K]

f'(x) = (4 arctan(7x))'

f'(x) = 4 (arctan(7x))'

By the chain rule,

f'(x) = 4/(1 + (7x)^2) * (7x)'

f'(x) = 28/(1 + 49x^2)

and hence

f'(4) = 28/(1 + 49*16) = 28/785

In case you're not sure about the derivative of arctan: If y = arctan(x), then x = tan(y). Differentiating both sides with respect to x gives

1 = sec^2y y' = (1 + tan^2y) y' = (1 + x^2) y'

==>  y' = 1/(1 + x^2)

Which fraction represents the decimal 0.8888
GrogVix [38]
<span> For this case we have the following decimal number:
 0.8888
 Since the number has 4 decimal places, then the first thing to do is multiply  and divide the number by 10000.
 We have then:
</span> 0.8888 * (10000/10000) = 8888/10000&#10;
<span> Simplifying we have:
</span> 8888/10000 = 4444/5000&#10;&#10;4444/5000 = 2222/2500&#10;&#10;2222/2500 = 1111/1250<span>
 Answer:
 A fraction that represents the decimal 0.8888 is:
 1111/1250</span>
