\\ \sf\longmapsto {\displaystyle{\int}}(1-x^3)^2dx

\\ \sf\longmapsto {\displaystyle{\int}}(1-x^6+2x^3)dx

\\ \sf\longmapsto x-\dfrac{x^{6+1}}{6+1}+2\dfrac{x^{3+1}}{3+1}

\\ \sf\longmapsto x-\dfrac{x^7}{7}+2\dfrac{x^4}{4}

\\ \sf\longmapsto x-\dfrac{x^7}{7}+\dfrac{x^4}{2}

Answer:

Start off by expanding the square:

x^6 -2x³ + 1.

Now, we can integrate it in dx:

∫x^6 - 2x^3 + 1 dx = ∫x^6 dx - 2∫x^3 dx + ∫1 dx = (x^7)/7 - 2((x^4)/4) + x = (x^7)/7 - (x^4)/2 + x.

That's the result!

Investment A 50 increases each year by 8% investment B 60 increases by 3 each year what year will investment A be bigger than be
UkoKoshka [18]

Answer:

After 10 years the investment A will be bigger than investment B.

Step-by-step explanation:

In Investment A, 50 increases each year by 8% and in investment B, 60 increases by 3 each year.

If after x years the investment A will be equal to investment B, then we can write the equation as

50(1 + \frac{8 \times x}{100}) = 60 + 3x

⇒ 50 + 4x = 60 + 3x

⇒ x = 10

Therefore, after 10 years the investment A will be bigger than investment B. (Answer)

Lita has a coin with heads on one side and tails on the other side. She is going to flip it in the air three times. What is the
inysia [295]

Answer:

The probability is 1/8

Step-by-step explanation:

In this question, we are tasked with calculating that if a coin is flipped three times, we have the outcome in the question; THH

Now before we go on to calculate this probability, we need to understand some technicalities. Flipping a coin can only result into two outcomes as there are only two sides of a coin. These are the head and the tail. What this means is that if a coin is flipped, we should only expect landing on the head and on the tail.

Now these opposite sides have equal probability. This means the probability of landing on the head = probability of landing on the tail. These probabilities are equal as they are the only two options we have. Hence, the probabilities are 1/2 each

Hence, P(H) = P(T) = 1/2

Now, we proceed to calculating the probability of HTT

this mathematically means P(H) * P(T) * P(T) = 1/2 * 1/2 * 1/2 = 1/8
