Help plz! Evaluate the following definite integral:<img src="https://tex.z-dn.net/?f=%5Cint%5Climits%5Ea_%7B-a%7D%20%7B%28a%5E%7
s344n2d4d5 [400]

Just use the power rule:

\displaystyle\int_{t=-a}^{t=a}(a^2-t^2)\,\mathrm dt=a^2t-\dfrac13t^3\bigg|_{t=-a}^{t=a}

We also could have use the fact that the integrand is even to write

\displaystyle\int_{t=-a}^{t=a}(a^2-t^2)\,\mathrm dt=2\int_{t=0}^{t=a}(a^2-t^2)\,\mathrm dt=2\left(a^2t-\dfrac13t^3\bigg|_{t=0}^{t=a}\right)

I'll continue with this expression since it's easier to evaluate (if only a little):

2a^3-\dfrac23a^3=\dfrac43a^3

Suppose we want to choose 5 objects,without replacement from 16 distinct objects
lesya692 [45]

Answer:

4368 ways

Step-by-step explanation:

We want to choose 5 objects,without replacement from 16 distinct objects.

We can use combination in this case. The formula for the combination is given by :

_{n}C_r=\dfrac{n!}{r!(n-r)!}

We have, n = 16 and r = 5

So,

_{16}C_5=\dfrac{16!}{5!(16-5)!}\\\\_{16}C_5=\dfrac{16!}{5!11!}\\\\=4368

So, there are 4368 ways in which we want to choose  5 objects,without replacement from 16 distinct objects.

A bedroom measures 9 feet long and 11 feet wide. A scale drawing is made using a scale factor of 112.
bazaltina [42]

Given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

<h3>What is the length of the bedroom in the scale drawing?</h3>

Scale factor is simply a measure for similar figures, who look the same but have different scales or measures.

To get new dimension;

New dimension = scale factor × current dimension

Given that;

  • Current length of the bedroom = 9ft
  • Current width of the bedroom = 11ft
  • Scale factor = 112
  • New length of the bedroom = ?

New dimension = scale factor × current dimension

New length of the bedroom = 112 × 9ft

New length of the bedroom = 1008ft

Therefore, given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.
