Answer:

C y = 2sin(1/3) x

Step-by-step explanation:

It's a sin function since y = 0 at x = 0

The amplitude is 2

There are 2 cycles in 12π

so the period is 6π

The x coefficent is then 2π/6π = 1/3

Answer

C y = 2sin(1/3) x

Need help with this

blondinia [14]

Answer:

r = √(3V/(πh))
r ≈ 1.78 cm

Step-by-step explanation:

Multiply by the inverse of the coefficient of r², then take the square root.

$V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{\pi h}{3}r^2\\\\r^2=\dfrac{3V}{\pi h}\\\\\boxed{r=\sqrt{\dfrac{3V}{\pi h}}}$

For V=50, h=15, this is ...

${r=\sqrt{\dfrac{3(50)}{\pi(15)}}=\sqrt{\dfrac{10}{\pi}}\approx\boxed{1.78\quad\text{cm}}$

How do you do number 1?

Alla [95]

Answer:

The decimal is not a rational number.

REASON:

A decimal can be a rational number if it fulfills any of the two conditions.

Condition 1:

It must be Terminating. This means that the decimal should have finite number of digits.

Condition 2:

If it is non-terminating decimal it should be Recurring. This means the decimal should repeat itself after some specific digits.

Part 3: Use the information provided to write the standard form equation of each circle

Ber [7]

Answer:

9. $\displaystyle (x - 7)^2 + (y - 15)^2 = 25$

8. $\displaystyle (x - 1)^2 - (y - 10)^2 = 49$

7. $\displaystyle (x + 5)^2 + (y + 19)^2 = 9$

Step-by-step explanation:

$\displaystyle [x - h]^2 - [y - k]^2 = r^2 → Hyperbola\:Equation \\ [x - h]^2 + [y - k]^2 = r^2 → Circle\:Equation \\ [h, k] → Centre$

According to the equations in the exercises, in the parentheses, ALL NEGATIVE SIGNS give the OPPOSITE terms of what they REALLY are, so be EXTREMELY CAREFUL with your translations:

9. [4, 11]

+ 3 + 4

_____

[7, 15] → (x - 7)² and (y - 15)²

8. [−2, 8]

+ 3 + 2

_____

[1, 10] → (x - 1)² and (y - 10)²

7. [−8, −14]

+ 3 - 5

______

[−5, −19] → (x + 5)² and (y + 19)²

** NOTISE THAT THE RADII NEVER ALTER.

I am joyous to assist you anytime.
