Write the quadratic function f(x) = x2 – 2x – 8 in factored form.
IRINA_888 [86]

Answer:

f(x) = (x-4)(x+2)

Step-by-step explanation:

f(x) = x^2 – 2x – 8

What 2 numbers multiply to -8 and add to -2

-4*2 = -8

-4+2 = -2

f(x) = (x-4)(x+2)

Suppose 300 nursing students took a certification test that is worth 100 points.
Alja [10]

Answer:

225 students scored 65 or better and 75 students scored 88 or better.

Step-by-step explanation:

We are given that The five-number summary for the scores of 300 nursing students are given :

Minimum = 40

Q_1 = 65

Median = 82

Q_3 = 88

Maximum = 100

Q_1 is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below Q_1 and about 75% lie above Q_1 .

Q_3 is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie belowQ_3 and about 25% lie above Q_3

i) .About how many students scored 65 or better?

Q_1 = 65

Since we know that 75% lie above Q_1 .

So, Number of students  scored 65 or better = 75\% \times 300 = \frac{75}{100} \times 300 =225

ii)About how many students scored 88 or better?

Q_3 = 88

Since we know that 25% lie above Q_3

So, Number of students scored 88 or better = 25\% \times 300 = \frac{25}{100} \times 300 =75

Hence 225 students scored 65 or better and 75 students scored 88 or better.

A parabola can be drawn given a focus of (6, -7)and a directrix of x=-2. What can be said about the parabola?
Komok [63]

If directrix= -7 and focus = (7,-3) the vertex is the midpoint between (7,-3) and (-7,-3) = (0,-3)

The parabola opens to the right. It's of the form x=a(y+3)^2

to solve for a, plug in another point on the parabola, directly above the focus (7,y) the distance from y to -3 is the same as from 7 to -7 = 14. 14-3 = 11, the point on the parabola is (7,11) plug that in to solve for a

7 = a(11+3)^2= 14^2(a)

a = 7/14^2 = 1/28

the parabola is x = (1/28)(y+3)^2 or

28x = (y+3)^2

the axis of symmetry is y=-3, the line through the focus and vertex and perpendicular to the directrix

the latus rectum is the distance from (7,11) to (7,-17), the two points on the parabola directly above and below the focus.

the parabola opens rightward when the focus is to the right of the directrix

the absolute value of p is the distance from the vertex to the focus or 7

1/4p  = a, the coefficient of y^2  =  1/28.
