Jack is learning to play the piano. Which has 88 keys. If there are 12 unique keys in each octave. How many complete octavs are

Anit [1.1K]

To find the amount of complete octaves there are on the piano, you must first divide 88/ 12; which is 7.333. Since the question is asking for the amount of complete octaves, you must round down to 7. Your final answer is 7 complete octaves.

6x+12y=15 -6+2y=c Solve for C

Alekssandra [29.7K]

Answer:

C = - 21 -6x

Step-by-step explanation:

6x + 12y = 15 (1)

- 6 + 2y = C (2)

multiply equation (2) by 6

- 36 + 12y = C (3)

subtract equation (1) from equation (3)

- 36 + 12y = C

6x + 12y = 15

___________

- 36 - 6x = C - 15

now we collect the terms (make C by itself)

- 36 + 15 - 6x = C (to do this we add 15 to both sides)

- 21 -6x = C

That's about as much as you can simplify it.

Hope this helps,

If the substitution u=x/2 is made, the intergal from 2 to 4 1-(x/2)^2/x dx =

stich3 [128]

$\displaystyle\int_2^4\frac{1-\left(\frac x2\right)^2}x\,\mathrm dx$

Setting $u=\dfrac x2$ gives $\mathrm du=\dfrac{\mathrm dx}2$ , or $2\,\mathrm du=\mathrm dx$ . This also makes $2u=x$ .

When $x\to2^+$ , you have $u\to\dfrac22=1$ , while when $x\to4^-$ , you have $u\to\dfrac42=2$ .

Putting everything together, you find that

$\displaystyle\int_2^4\frac{1-\left(\frac x2\right)^2}x\,\mathrm dx=\int_1^2\frac{1-u^2}{2u}(2\,\mathrm du)=\int_1^2\frac{1-u^2}u\,\mathrm du$

which means (B) is the correct answer.
