Answer:
The coefficient of the squared expression in the parabola equation is 
Step-by-step explanation:
The equation of a parabola in its vertex form is:

Where the vertex of the parabola is the point (h, k)
a is the ceoficiente of the term to the square.
We need to find the equation of a parabola that has its vertex in the point:
(-5, -2)
So:

Therefore the equation is:

We know that the point (-4, 2) belongs to this parable. Then we can find the value of a by replacing the point in the equation of the parabola

Finally the coefficient is a = 4
Answer:
50.41 minus 1.71 is 48.70 divided by 5 is 9.74
Answer: Trapezoidal prism
A figure with 4 sides and a parallel side is called a trapezoid, this is a 3 dimentional trapezoid which is called a trapezoidal prism.
Answer:
Step-by-step explanation:
Find, find the total increase in salary for 7 years;
If 1 year = $4,000
7 years = ?
=7*4000
=28,000 in total
Original salary = $169,300
Add the total increase in salary to the original salary;
169,300 + 28,000 = 197,300
Therefore, in 7 years, the salary would be $197,300
