<em>x = 4</em>
<em>Here is why:</em>
When adding up all angles of a triangle, they will be equal to 180.
Let's add ∠B and ∠C together.
Let's subtract it from 180, that will be the value of ∠A.
Now we can set ∠A equal to 49.
Subtract 9 from both sides.
Divide.
<u>x = 4</u>
If the discriminant is positive,that means that there are roots that are real and therefore, when y=0, the roots are there and for the quadratic to meet it has to go down (or up if in ax²+bx+c a is negative). If the discriminant is 0, that means that since the x value of the vertex is -b/2a and if you have
x=
and b^2-4ac=0, we're left with 0 and we are therefore left with -b/2a as the vertex and the vertex being the x intercept. If the discriminant is negative, that means that there is no y intercept and the vertex therefore has to be over y=0
Answer:
$93.33 per dose
Step-by-step explanation:
$1.4×10⁶/(7.5 kg) × (1 kg)/(1000 g) × (0.5 g)/(1 dose)
= (1.4×10⁶×0.5)/(7.5×10³) $/dose = 700/7.5 $/dose ≈ $93.33/dose

Converting dollars per kilogram to dollars per dose involves units conversion from kilograms to doses. We have done it in two steps, first to grams, then to doses.
