Answer:
-26/8+7=15/4 or 3 3/4
Step-by-step explanation:
The tangent line to the curve has slope equal to 
at the point (2, -1). We have, by implicit differentiation,
At the point (2, -1), the slope is then 2/9, so the tangent line has equation
Answer:
125=12x+40
Step-by-step explanation:
Let the number of hours be x
And the total amount be =$125
We already have $40
Hence the expression is
125=12x+40
If we solve for x, the answer gotten is the number of hours
Answer:
3x+18
Step-by-step explanation:
6+3(x+4)=6+3x+12
=3x+18
To solve this we use the
equation,
<span> M1V1 = M2V2</span>
<span> where M1 is the
concentration of the stock solution, V1 is the volume of the stock solution, M2
is the concentration of the new solution and V2 is its volume.</span>
<span>
</span>
<span>M1 = .80 g H2SO4 / g solution (1018 g solution / L solution ) (1 mol / 98.08) = 8.30 M</span>
<span>
</span>
<span>8.30 (V1) = (5.0 M) (1.5 L)</span>
<span>V1 = 0.9036 L or 903.6 mL of the stock needed</span>
