skelet666 [1.2K]

Answer:

13,000ml

Step-by-step explanation:

1000ml = 1L.

We can rewrite this forumla as:

yL x 1000=ml. y=the number of liters.

In this problem, y=13. Thus:

13Lx1000= 13,000ml

I hope this helps!

If f(x) = 3x to the 2nd+ 1 and g(x) = 1-x, what is the value of (f-g)(2)?

melisa1 [442]

$\displaystyle\\f(x)=3x^2+1\\g(x)=1-x\\\\(f-g)(x)=f(x)-g(x)=3x^2+1-(1-x)=3x^2+1-1+x=\boxed{3x^2+x}\\\\(f-g)(2)=f(2)-g(2)=3\cdot2^2+2=3\cdot4+2=12+2=\boxed{14}$

DESPERATELY NEED HELP

In-s [12.5K]

Remark

You must use the sin law to find this.

$\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}$

Multiply through by 12

12 * $\dfrac{Sin(75)}{22} = \dfrac{Sin(x)}{12}$ *12

$\dfrac{12*sin(75)}{22} = \text{sin(x)}$

0.5269 = sin(x)

Now you have to use the inverse of the sine function.

Use your calculator for that

2nd F

sin-1

(0.5269)

= 31.79 degrees. <<<<<< Answer.

There sometimes is a second answer. I don't think there is in this case.
