Answer:

see explanation

Step-by-step explanation:

Using the tangent ratio in the lower right triangle.

tan25° = $\frac{opposite}{adjacent}$ = $\frac{h_{1} }{300}$ ( multiply both sides by 300 )

300 × tan25° = h₁ , then

h₁ ≈ 140 m ( to the nearest metre )

Using the tangent ratio in the outer right triangle

tan60° = $\frac{opposite}{adjacent}$ = $\frac{h_{1}+h_{2} }{300}$ ( multiply both sides by 300 )

300 × tan60° = h₁ + h₂ ≈ 520 m ( to the nearest metre )

Thus

h₁ + h₂ = 520

140 + h₂ = 520 ( subtract 140 from both sides )

h₂ = 380 m

In conclusion

h₁ = 140 m and h₂ = 380 m

Find the indefinite integral. (Use C for the constant of integration.) e2x 25 e4x dx.

Sladkaya [172]

Answer:

The solution is $\frac{1}{10} * tan^{-1}[\frac{e^{2x}}{5} ] + C$

Step-by-step explanation:

From the question

The function given is $f(x) = \frac{e^{2x}}{ 25 + e^{4x}} dx$

The indefinite integral is mathematically represented as

$\int\limits {\frac{e^{2x}}{ 25 + e^{4x}}} \, dx$

Now let $e^{2x} = u$

=> $\frac{du}{dx} 2e^{2x}$

=> $2 e^{2x}dx = du$

$\int\limits {\frac{e^{2x}}{ 25 + e^{4x}}} \, dx = \int\limits {\frac{1}{ 2(25 + u^2)} } \, du$

$= \frac{1}{2} \int\limits {\frac{1}{ 25 + u^2)} } \, du$

$= \frac{1}{2} \int\limits {\frac{1}{ 5^2 + u^2)} } \, du$

$= \frac{1}{2} \frac{tan^{-1} [\frac{u}{5} ]}{5} + C$

Now substituting for u

$\frac{1}{10} * tan^{-1}[\frac{e^{2x}}{5} ] + C$

trasher [3.6K]

Answer:

D. 30

Step-by-step explanation:

6 ÷ 1/5 -given expression

6 x 5 -use the keep, change, flip method, where you keep the first number, change the division sign to a multiplication sign, and flip the fraction that comes after the symbol.

6 x 5 = 30

30 is the answer
