Answer:

Step-by-step explanation:
From the question we are told that:
Mass 
Amount of NaCl IV 
Rate 
Generally the equation for fluid rate be for your IV pump is mathematically given by

Since
Rate is
30ml/kg/hr at 1kg patient Weight
Therefore


For the first point, remember this simple rule: every exponential function
always returns
when evaluated at
. In fact,
for every possible base
.
So, we can see that the graph of the exponential passes through the point
where
appears to be between 1 and 2. So, the only feasible option would be
, because it passes throught the point
because
.
The other functions are wrong because:
would pass through
, which would be between 0 and 1 on the y axis
would pass through
, which would be between 2 and 3 on the y axis
would pass through
, which would be between 0 and 1 on the y axis
As for the second question, you simply have to plug in the values: the function

means that you have to choose an input, x, and use it as exponent for 7. So, if you choose x=2, it means that you have to give exponent 2 to 7, i.e. you replace the x with the specific value, 2.
So, the expression becomes

Answer:
1:5
Step-by-step explanation:
For this problem, you just have to evaluate the proportion of the length of the sides between triangles nmo and kml.
So LM = 12, which corresponds to OM = 60 (12 X 5 = 60)
KM = 10, which corresponds to NM = 50 (10 X 5 = 50)
Answer:
0.4375
Step-by-step explanation:
To find the decimal equivalent you have to divide the numerator by the denominator.
7 ÷ 16 = 0.4375
