Three roots of a fifth degree polynomial function f(x) are -2, 2, and 4 + i. Which statement describes the number and
nature of all roots for this function?
A) f(x) has two real roots and one imaginary root.
B) f(x) has three real roots.
C) f(x) has five real roots.
D) f(x) has three real roots and two imaginary roots.
Answer:
D.
Step-by-step explanation:
Its a fifth degree function so it will have 5 roots.
One of the 3 roots is complex ( imaginary):- 4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.
The fifth root must be real because you cant have just one imaginary root.

what percent is 18 of 20
Answer:
90%
Step-by-step explanation:
[tex]\frac{18}{20} = \frac{90}{100}[/tex] [tex]\frac{90}{100} =[/tex] 90%I hope this helps!
Answer:
90%
Step-by-step explanation:
% itself means out of 100 so yea:
18/20 times 100
1800/20
90/100
90%
Another way u could do is just multiply a number that would make 20 into 100, so:
(18/20)5/5
90/100 = 90%

Given data,
The square on the right is a scaled copy of square on left
Here, we want to get the scale factor
Define Scale factor :
Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures.
To get the scale factor, we divide corresponding sides by each other
That, we have that,
= (19/2) / 19
= 9.5 / 19
= 0.5 (see image)
Therefore,
The scale factor is 1 to 0.5

Answer:
1/4
Step-by-step explanation:
o=area of first square
t=area of second square
o=19*19
o=361
t=19/2 * 19/2
t=19*19/(2*2)
t=361/4
t=o * x
361/4=361*x
x=1/4 ==> scale factor

The number of ducks swimming In a lake decreased by 1/4 between last year and this year. last year there were 60 ducks in the lake. What is the population this year? If you get stuck consider drawing a diagram.
Answer:
Given: Population of ducks in lake, last year is 60.
Also, the population of ducks this year decreased by 1/4 th over the last year.
So, the population of ducks this year is = 60*(1-1/4)
= 60*(3/4)
= 45
Therefore, the population of ducks this year is 45 ducks.

Write a function in any form that would match the graph shown below.
Answer:
f(x) = 2x^3 + 3x^2 - 4x - 6
Step-by-step explanation:
The graph that we can see above is the graph of a cubic equation
A cubic equation is one in which the highest polynomial power is 3
An example of this can be seen below;
f(x) = 2x^3 + 3x^2 - 4x - 6

Which polynomial function has a leading coefficient of 2, root -4 with multiplicity 3, and root 10 with multiplicity 1?
O f(x) = 2(x-4)(x-4)(x - 4)(x + 10)
O fx) = 2(x + 4)(« + 4)(« + 4)(-10)
O f) =3K – 4)(«-4)0x + 10)
O f()= 3(x + 4)(x + 4)(K- 10)
Answer:
f(x) = 2(x+4)(x+4)(x+4)(x-10)
Step-by-step explanation:
Here, we want to write a polynomial function with leading coefficient of 2, root - 4 with multiplicity 3 ( meaning it appears 3 times);
and root 10 with multiplicity 1
If x = -4
Then in linear form, we have x + 4
if x = 10, in linear form, we have x -10
So the polynomial is;
f(x) = 2(x+4)(x+4)(x+4)(x-10)
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line is m = 14 / 17
The slope of a line is that the magnitude relation of quantity the quantity the number that y will increase as x will increase some amount. Slope tells you ways steep a line is, or what proportion y will increase as x will increase. The slope is constant (the same) anyplace on the road.Slope = rise/runIf y represents the vertical direction on a graph, and x represents the horizontal direction, then this formula becomes:Slope = (Change in y)/(Change in x)The line representing "rise" and " run" is given below
The vertical distance is said to be "rise" and from the graph it is equal to 14.
The horizontal distance is said to be "run" and from the graph it is equal to 17 .
According to the slope formula , we get
m = 14 / 17

Nancy's morning routine involves getting dressed, eating breakfast, making her bed, and driving to work. Nancy spends ⅓ of the total time in the morning getting dressed, 10 minutes eating breakfast, 5 minutes making her bed, and the remaining time driving to work. If Nancy spends 35 ½ minutes getting dressed, eating breakfast, and making her bed, how long is her drive to work?
Answer: 26 minutes
Step-by-step explanation:
Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.
Time getting dressed = ¹/₃x
Eating breakfast = 10 mins
Making bed = 5 mins
¹/₃x + 10 + 5 = 35 ½
¹/₃x + 15 = 35 ½
¹/₃x = 35 ½ - 15
¹/₃x = 20 ½
x = 20 ½ / ¹/₃
= 61.5 minutes
Total morning routine is is 61.5 mins
Time taken to drive to work is;
= 61.5 - 35 ½
= 26 minutes
If the height of Mount Everest is about 8.8 time 10 to the third power meters and the height of the Empire State Building is about 3.8 times 10 to the second power meters which of these statements is a true
Answer: C. Mount Everest is about 23 times as tall as the Empire State Building
Step-by-step explanation:
The options are:
A.There is no way to compare these heights
B.Mount Everest is about 40 times as tall as the Empire State Building
C.Mount Everest is about 23 times as tall as the Empire State Building
D.The Empire State Building is about 23 times as tall as Mount Everest
Mount Everest = 8.8×10^3 meters = 8800 meters
Empire State Building = 3.8×10^2 = 380 meters
Mount Everest is (8800 / 23) = 33 times as tall as the Empire State Building. Therefore, the correct option is C.
