Answer:

10 = C

<em>Let's Find Angles :</em>

<em>sin BCA = 6/10 = 0.6 => 37 degree</em>

<em>90 degree + 37 degree = 127 degree</em>

<em>Angle BAC = 180 degree - 127 degree = </em>53 degree

You want 40% of 140 gallons to be methane,

so 60% of 140 gallons is water

methane: 0.4(140) = 56 gallons

water: 0.6(140) = 84 gallons

1. Consider f(x) = 3x - 5

Rzqust [24]

Answer:

Step-by-step explanation:

Here we have the function

$f(x)=3x-5$

We want to find the following ratio:

$\frac{f(x+h)-f(x)}{h}$

Note that the limit of this for $h\rightarrow 0$ is equivalent to the derivative of the function.

Here we have:

$f(x+h)=3(x+h)-5=3x+3h-5$

And

$f(x)=3x-5$

Therefore we have

$f(x+h)-f(x)=3x+3h-5-(3x-5)=3h$

And therefore,

$\frac{f(x+h)-f(x)}{h}=\frac{3h}{h}=3$
