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.

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.
What is the sum of the first 50 terms in the arithmetic sequence 5, 8, 11, 14,...?
Answer:
3925
Step-by-step explanation:
We can use the formula [tex]an=a1+(n-1)d[/tex] to find 50th term where:
[tex]an[/tex] is the nth term in the sequence
[tex]a1[/tex] is the first term in the sequence
[tex]d[/tex] is common difference between terms
[tex]5+(50-1)*3=152[/tex]
We also use the formula [tex]Sn=n*(a1+an/2)[/tex] to find the sum
[tex]50*(\frac{5+152}{2})=3925[/tex]

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.
Answer:
Mount Everest is about 23 times as tall as the Empire State Building. Hope that helps!
Garden soil costs $5.00 per a 2 cubic foot bag at lows. You have raised rectangular garden thag is 8 feet by 4 feet and you wish the depth of the soil to be 6 inches deep. How much will it cost to buy the bags of soul for your garden
Answer:
$40
Step-by-step explanation:
Step one:
given data
Garden soil costs $5.00 per a 2 cubic foot bag
dimension of rectangular garden raised
8 feet by 4 feet , depth is 6 in
6 in to feet= 0.5ft
the volume of the soil in the garden is
volume= 8*4*0.5= 16ft^3
Step two:
now if 2ft^3 cost $5
16ft^3 will cost x
cross multiply
x*2=16*5
divide both sides by 2
x= 16*5/2
x=80/2
x=$40

Elisa withdrew $27 at a time from her bank account and withdrew a total of $216. frances withdrew $46 at a time from his bank account and withdrew a total of $184. who made the greater number of withdrawals?
Using the concept of division we can find the number of times Elisa and Frances withdraw the money.
What is division?Division is one of fundamental mathematical operations, which breaks a bigger number into smaller groups with the same number of components.
The amount withdrawn by Elisa at a time =$27 The amount withdrawn by Elisa in total =$216
The number of times Elisa withdrew
=[tex]\frac{total amount withdrawn}{amount withdrawn per time}[/tex]
=[tex]\frac{216}{27}[/tex]
=8
The amount withdrawn by Frances each time=$46
The amount withdrawn by Frances in total=$184
The number of times Frances withdrew
=[tex]\frac{total amount withdrawn}{amount withdrawn per time}[/tex]
=[tex]\frac{184}{46}[/tex]
=4
The number of times Elisa withdrew is 8 while the number of times Frances withdrew is 4.This implies Elisa has made withdrawals than Frances.

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

Adding 7 to both sides.
Subtracting 5 from both sides.
Subtracting 7 from both sides.
Dividing by 5 on both sides.
Answer:
The answer is adding 7 to both sides.
Step-by-step explanation:
5x-7=18
+7 +7
5x= 25
x=5
Answer:
Answer: Adding 7 to both sides.
Step-by-step explanation:
You always do the "inverse" of the number without the variable next to it and either "add" or "subtract" it to the other side.
Ex: 7x - 3 = 18
In this case, you would add the 3 to the other side.
7x - 3 = 18
+ 3 +3
7x = 21
7x 7x
x = 3

1. Order the numbers from least to greatest. 66 V21, 5.38 3
Answer:
3, 5.38, 66, V21
Step-by-step explanation:
I assumed that V was the roman numeral V, which is equivalent to the number 5. I then multiplied 5 by 21 which is 105. If this is not the case and they simply wanted us to replace the v with a 5, then the answer would still be correct because 521 is greater than all the numbers in this set. Hope this helps.

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
Then the slope of the line through C(2, 5) and D(4,7) will be given as,
m = (y₂ - y₁) / (x₂ - x₁)
m = (7 - 5) / (4 - 2)
m = 2 / 2
m = 1
Thus, the slope of the line through C(2, 5) and D(4,7) will be 1.

How to find the voluume of the sphere?The volume of a sphere of radius R is given by the formula:
V = (4/3)*3.14*R³
Here we know that the diameter is 6 inches, and the radius is half of that, then the radius is:
R = 6in/2 = 3in
Replacing that in the formula we will get:
V = (4/3)*3.14(3in)³
