Answer:
0.0726mL
Step-by-step explanation:
Let's find the answer by using the following formula:
(subcutaneous dose)=(milliliters of the injection)*(drug concentration)/(child weight)
Using the given data we have:
(0.01mg/kg)=(milliliters of the injection)*(1mg/mL)/(16lbs)
milliliters of the injection=(0.01mg/kg)*(16lbs)/(1mg/mL)
Notice that the data has different units so:
1kg=2.20462lbs then:
16lbs*(1kg/2.20462lbs)=7.25748kg
Using the above relation we have:
milliliters of the injection=(0.01mg/kg)*(7.25748kg)/(1mg/mL)
milliliters of the injection=0.0726mL
Answer:
a = 13 and b = 12-5i
Step-by-step explanation:
We need a common denominator
3+2i 5-i
---------- + ---------
3-2i 2+3i
(3+2i) (2+3i) (5-i)(3-2i)
------------------ + --------------------
(3-2i) (2+3i) (2+3i) (3-2i)
Foil the numerators
6 +4i+9i+6i^2 +15-3i-10i+2i^2
------------------ --------------------
(2+3i) (3-2i)
Combine like terms
21 +8i^2
------------------
(2+3i) (3-2i)
We know that i^2 = -1
21 +8(-1)
------------------
(2+3i) (3-2i)
21 -8
------------------
(2+3i) (3-2i)
13
------------------
(2+3i) (3-2i)
Foil the denominator
13
---------------
6 +9i -4i -6i^2
Combine like terms
13
----------------
6+ 5i -6(-1)
13
----------
12 +5i
We know have
13
-------------
12 + 5i
Multiply by the conjugate
13 ( 12-5i)
------------- * -------------
12 + 5i 12 -5i
13 (12-5i)
--------------
144 +25
13(12-5i)
-------------
169
12-5i
------------
13
The parentheses are (12-5i)/13
We need the reciprocal to make the equation become 1
which is 13/ 12-5i
a = 13 and b = 12-5i
Answer:C
Step-by-step explanation:
For every function; f(x) = y
Each value of 'x' produces only one output 'y'
A,B and D are not functions because this rule is violated. It is observed that on the graphs of A,B and D, there exists a value of x that produces two outputs(y).
Hence, C is the correct option as it produces only one output 'y' for each value of x.
Answer:
5 is your answer
Step-by-step explanation:
Yes, so first plug in 4 for x
2(4)-3
Then multiply 2x4 which is 8
8-3 is 5
