Answer: First.

Step-by-step explanation:

Let's find the speed of the first airplane:

2800 ÷ 5 = 560 (miles per hour)

Let's find the speed of the second plane:

3885 ÷ 7 = 555 (miles per hour)

Thus, the first plane flies faster than the second.

The first plane is faster.

The first plane travels at 560 miles per hour. The comparisons are 2 hours apart. Add 560 2 times to 2800 and you get 3,920 which is greater than 3,885, the original number of MPH for the second plane.

Meaning the first plane is faster.

Identify the function that is exponential.

den301095 [7]

Please, for clarity, indicate exponentiation using the " ^ " symbol.

y = - 3x^5 ("Negative three times the 5th power of x")

y = 3x^8

y - -3(0.5)^x

y = -2^4

An exponential function has an exponent which is variable, where the base stays constant; the base cannot be a negative number or a zero. The third answer choice is the correct one, as we raise the constant 0.5 to the power x:

y = -3(0.5)^x

To visit his grandmother, Michael takes a motorcycle 3.853.853, point, 85 kilometers and a horse 3.323.323, point, 32 kilometers

liq [111]

Answer: $7.17\ kilometers$

Step-by-step explanation:

<h3> The exercise is: "To visit his grandmother, Michael takes a motorcycle 3.85 kilometers and a horse 3.32 kilometers. In total, the journey takes 50.54 minutes. How many kilometers is Michael's journey in total?"</h3>

To solve this exercise you must pay attention to the data given.

According to the information provided in the exercise, Michael's journey is divided into two parts:

Part 1: $3.85\ kilometers$ (Traveling in a motorcycle)

Part 2: $3.32\ kilometers$ (Traveling in a horse)

Based on the given data, you can conclude that the the total distance in kilometers of Michael's journey to the house to his grandamother, is the sum of those distances ( $3.85\ kilometers$ and $3.32\ kilometers$ )

Therefore, you need to add them in order to solve the exercise.

So, You get that the result is:

$Total=3.85\ kilometers+3.32\ kilometers\\\\Total=7.17\ kilometers$

Is it true that the integral LaTeX: \int x^2e^{2x}dx ∫ x 2 e 2 x d x can be evaluated using integration by parts? If so, state t

Marysya12 [62]

Answer:

Yes the integral can be evaluated by integration by parts as solved below.

Step-by-step explanation:

$\int x^{2}e^{2x}dx$

Taking algebraic function as first function and exponential function as second function we have

$\int x^{2}e^{2x}dx=x^{2}\int e^{2x}dx-\int (x^{2})'\int e^{2x}dx\\\\=x^{2}\frac{e^{2x}}{2}-\int 2x\times \frac{e^{2x}}{2}dx\\\\\frac{x^{2}e^{2x}}{2}-\int xe^{2x}dx\\\\Now\\\\\int xe^{2x}dx=x\int e^{2x}dx-\int 1\cdot \int e^{2x}dx\\\\=\frac{xe^{2x}}{2}-\int \frac{e^{2x}}{2}dx\\\\\frac{xe^{2x}}{2}-\frac{e^{2x}}{4}\\\\\therefore \int x^{2}e^{2x}dx=\frac{x^{2}e^{2x}}{2}-\frac{xe^{2x}}{2}+\frac{e^{2x}}{4}$
