For a Cosine function with amplitude =0.75 and period =10 , what is y(4) ?

frez [133]

We need to find a cosine function:

$y(x)=acos(bx) \\ \\ where: \\ \\ \left|a\right|=Amplitude \\ \\ Period=\frac{2\pi}{b}$

The amplitude represents half the distance between the maximum and minimum values of the function and the period goes from the x-value of one peak to the x-value of the next one. Therefore:

$a=0.75 \\ \\ b=\frac{2\pi}{10}=\frac{\pi}{5}$

Finally:

$\boxed{y(x)=0.75cos(\frac{\pi}{5}x)}$

And y(4) is:

$y(4)=0.75cos(\frac{\pi}{5}\times 4) \\ \\ \therefore \boxed{y(4)=-0.60}$

Plz help I need it now <br>plz answer directly without files or links

vivado [14]

1 L = 1000 mL
1 kg = 1000 g

You can use this to convert the equations.

200 mL of paint x 5 = 1000 mL (1 liter)
40 g x 5 = 200 grams of paint powder
200 g x 20 = 4000g of paint powder for 20 liters of paint
4000g/600g = 6 2/3

You’ll need 7 packets of paint powder.
