Consider the quadratic function f (x) = x2 - 5x + 6. What does b = ?
2 answers:
Answer:
b is the coefficient of the middle term. In this case, -5
Step-by-step explanation:
In a linear equation, the function is in the form of y=mx+b
In a linear equation <u>m</u> is the slope. <u>b</u> is a constant, and it is the y-intercept.
f(x) represents the "y" value obtained when a given number is plugged in to x.
In a quadratic equation, (and it would be helpful to insert a carat ^ [shift + 6] before the exponent so it is clear)
the form is a and b are the coefficients. if none, "1" is understood.
the exponent will determine the shape of the parabola.
The b will determine how far to the left or right the parent graph is transformed. ( divide by 2 and use the opposite sign)
but the c is a constant and still indicates the y-intercept.

Answer:
Yes the sales manager claims can be refuted based on the calculated percentages
Step-by-step explanation:
<u>From the table attached below </u>
Total number of customers = 200
<em>Calculated percentages</em><em> </em>
customers that prefer whole life insurance = 90 = 90/200 = 45%
customers that prefer universal life insurance = 15 = 15/200 = 7.5%
customers that prefer Annuities = 95 = 95/200 = 47.5
<em>Expected percentages:</em>
whole life = 20%
Universal life = 10%
Life Annuities = 70%

Step-by-step explanation:
Hi there!
We are given the points (2, 7) and (-6, -2). We want to find the distance between them. To do that, we can use the distance formula
The distance formula is given as , where
and
are points
We have 2 points, which is what we need to find the distance, but let's label their values to avoid any confusion
Now substitute those values into the formula:
Simplify the values under the radical:
Raise to the second power:
Add the numbers under the radical together
The answer can be left as that, as the radical cannot be simplified.
Hope this helps!
