Answer:
11
Step-by-step explanation:
We evaluate W(x)=3•3^x+3 + 2 at x = -2 by substituting -2 for each instance of x:
But first note that we must enclose x + 3 inside parentheses:
W(x)=3•3^(x+3) + 2.
Substituting -2 for x, we get:
W(-2)=3•3^(-2+3) + 2, or
W(-2)=3•3^(1) + 2, or
W(-2)=9 + 2 = 11
The equation of the volume of a cone is,
V = (1/3)Bh
where B is the area of the base and h is the height. The solid that we are looking for is that which has an equation of
V = Bh
for the volume. The answer is <em>CYLINDER. </em>
Answer:
The safe dose for the child is:
Step-by-step explanation:
We know that the conversion factor is 40 mg/kg/day
The child weighs 16 kg. This means that 40 mg per day corresponds to each kilogram of the child.
So to know how many milligrams per day correspond per day we must multiply 16 kg by the conversion factor
