Part A would be $75+.$55m and part B would be $165 +$75=$240
Answer:
El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.
Step-by-step explanation:
- First, the data must be taken into account to create the equations:
- Where:
X = Number of polio vaccines and Y = Number of measles vaccines.
- 4X + 2Y = 184; (Equation 2)
Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.
- We clear the variable that we want to find in each equation:
- Y = 60 - X; (And we call it equation 3)
- Y = (184-4X) / 2; (And we call it equation 4)
- Now both equations are equalized in terms of the same variable:
- Then X is cleared to find its value:
- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values of Y
- Finally, both values are used to see if equation 2 gives us the correct data:
- The answer is given:
Dr. Potter gave 32 polio and 28 measles vaccines.
Given that

attains a maximum at

, it follows that

at that same point. So integrating once gives



and so the first derivative is

.
Integrating again, you get


You know that this curve passes through the point (2, -1), which means when

, you have

:


and so
Answer:
= −3
Step-by-step explanation:
Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.
<u>Step 1:</u> <em>Expand.</em>
−40 − 6
− 1 = 7
− 2
<u>Step 2:</u> <em>Simplify −40 − 6</em>
<em> − 1 to −6</em>
<em> − 41.</em>
−6
− 41 = 7
− 2
<u>Step 3:</u> <em>Add 6</em>
<em> to both sides.</em>
−41 = 7
− 2 + 6
<u>Step 4:</u> <em>Simplify 7</em>
<em> − 2 + 6</em>
<em> to 13</em>
<em> − 2.</em>
−41 = 13
− 2
<u>Step 5:</u><em> </em><em>Add 2 to both sides</em>
−41 + 2 = 13
<u />
<u>Step 6:</u> <em>Simplify −41 + 2 to −39.</em>
−39 = 13
<u>Step 7:</u><em> </em><em>Divide both sides by 13.</em>
−
= 
<u>Step 8:</u> <em>Simplify </em>
<em> to 3.</em>
−3 = m
<u />
<u>Step 9:</u> <em>Switch sides.</em>
= −3
