Answer:

½ ln 3

Step-by-step explanation:

∫ sec²x / tan x dx

If u = tan x, then du = sec²x dx.

∫ du / u

ln|u| + C

ln|tan x| + C

Evaluate between π/4 and π/3.

ln|tan(π/3)| + C − (ln|tan(π/4)| + C)

ln|√3| + C − ln|1| − C

ln(√3)

½ ln 3

Answer:

The answer is 1st point.

Step-by-step explanation:

You can seperate everything out and multiply together :

(5xy²z³)^2/5

= (5^2/5) × (x^2/5) × (y²^2/5) × (z³^2/5)

= (⁵√25) × (⁵√x²) × (⁵√y⁴) × (⁵√z⁶)

= ⁵√(25x²y⁴z⁶)

Solve for j 6j+16=4j-10
prisoha [69]

\text {Hello! The answer to your problem is j=-13}

\text {Subtract 4j:}\\\text {6j+16-4j=4j-10-4j}\\\text {2j+16=-10}

\text {Subtract 16:}\\\text {2j+16-16=-10-16}\\\text {2j=-26}

\text {DIVIDE both sides by 2:}\\\text {2j/2=-26/2}\\\text {x=-13}

\text {Hope this helps!}\\\\\text {-LimitedX}

Cheryl solved a problem: 84 ÷ 0.01 = 8,400.
Alexandra [31]

Answer:

Cheryl is correct.

Step-by-step explanation:

Cheryl solved a problem : 84 ÷ 0.01 = 8,400.

This is absolutely right.

When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.

To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.

\frac{84\times 10}{0.01\times 10} = \frac{840}{0.1}

to make divisor a whole number we will again multiply both the numbers by 10.

\frac{840\times 10}{0.1\times 10} = \frac{8400}{1} = 8,400

Now answer would be 8400.

Therefore, Cheryl is correct.
