<h3>
Answer: 112</h3>
=========================================================
Explanation:
The angle adjacent to the 146 degree angle is 180-146 = 34 degrees.
In other words, the angles 34 and 146 combine to 180. These angles are supplementary.
The tickmarks on this triangle tell us it is isosceles. The angles opposite the congruent sides are congruent angles. So the unmarked interior angles (not marked x) are 34 degrees each.
Now use the fact that any triangle has its interior angles always add to 180
x+34+34 = 180
x+68 = 180
x = 180-68
x = 112
For this case what we must do is find a quadratic function that is already factored.
This is because in the factored quadratic equations, it is easier to observe the zeros of the function.
In this case, the zeros of the function represent the time at which the company did not make any profit.
We have the following equation:
p (t) = 40 (t - 3) (t + 2) (t - 5) (t + 3)
We observed that there was no gain in:
t = 3
t = 5
The other roots are discarded because they are negative
Answer:
a.p (t) = 40 (t - 3) (t + 2) (t - 5) (t + 3)
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.
Blue: 6/20 or 1/5
Red: 3/20
Yellow: 2/20 or 1/10
