The vertex of the given quadratic polynomial function is (6, 8)
A quadratic polynomial function is the one which can be represented in the form ax² + bx + c = y where a, b and c are coefficients and x, and y are independent and dependent variables respectively. A parabola is formed when the quadratic polynomial is plotted on graph. The x coordinate of the vertex can be found using formula (-b/2a) and y coordinate can be found by putting the value of x in the equation.
Given polynomial function x² - 12x + 44
Now, x = (-b/2a)
x = (12/2)
=> x = 6
Now, y = 6² - 12×6 + 44
y = 36 - 72 + 44
=> y = 8
Therefore, Vertex = (6, 8)

Answer:
t=9
Step-by-step explanation:
All we need to do is to find out how much is 3/8 of 3424. We can do it in at least two ways:
1. Divide 3424 by 8 and then multiply the result by 3
2. Just multiply 3424 by 3/8
So:
3424 / 8 = 428
428 * 3 = 1284
or:
3424 * 3/8 =
= 428 * 3/1 =
= 428 * 3 =
= 1284
Answer: Manfred hiked 1284 miles.
Answer:
<u>The correct answer is G. $22,436.40</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Jelena's average annual salary = $ $53,420
Expected annually pension to receive from Social Security = 42% of her average annual salary
2. How much can Jelena expect to receive from Social Security annually if she were to retire today?
Expected annually pension to receive from Social Security = 42% of her average annual salary
Expected annually pension to receive from Social Security = 53,420 * 0.42 = $ 22,436.40
<u>The correct answer is G. $22,436.40</u>
