Answer:
44,000 shares in a blue-chip company
Step-by-step explanation:
So since Johnson had 22,000 shares in a blue-chip company and it split 2:1, we multiple the beginning number of shares by 2 because they split into 2 different shares.
22,000*2=44,000
(x+5) is a factor of R(x)=x^4+5x^3-16x^2-80x. What are the zeros of the function R(x)?
A) 2, 3, -4, -5 B) 0, 3, -3, -5
C) 0, 3, 4, -5 D) 0, 4, -4, -5 E) 0, 16, -16, -5
The zeros of the function R(x) will be 0 , 4 , -4 , -5.
The equation given to us is
[tex]x^{4}[/tex] + 5[tex]x^{3}[/tex] - 16[tex]x^{2}[/tex] - 80x = 0
Take x common
x( [tex]x^{3}[/tex] + 5[tex]x^{2}[/tex] - 16x - 80 ) = 0
from here we get one factor of x as 0.
Now
[tex]x^{3}[/tex] + 5[tex]x^{2}[/tex] - 16x - 80 = 0
It is given that x + 5) is a factor of this equation. so we will divide the equation by (x + 5).
After dividing it by (x + 5) we get [tex]x^{2}[/tex] - 16
Which can be written as [tex]x^{2}[/tex] - [tex]4^{2}[/tex] = (x + 4) (x - 4)
From here we get rest of the two roots of the equation.
Therefore four zeros of the function will be 0 , 4 , -4 , -5.

Answer:
D) 0, 4, -4, -5
Step-by-step explanation:
Given polynomial:
[tex]R(x)=x^4+5x^3-16x^2-80x[/tex]
Given (x + 5) is a factor of R(x), use long division to find the other factor:
[tex]\large \begin{array}{r}x^3-16x\phantom{)}\\x+5{\overline{\smash{\big)}\,x^4+5x^3-16x^2-80x\phantom{)}}}\\{-~\phantom{(}\underline{(x^4+5x^3)\phantom{-b))))))))))))}}\\-16x^2-80x\phantom{)}\\-~\phantom{()}\underline{(-16x^2-80x)\phantom{}}\\0\phantom{)}\\\end{array}[/tex]
Therefore:
[tex]R(x)=(x^3-16x)(x+5)[/tex]
Factor out x from the first factor:
[tex]R(x)=x(x^2-16)(x+5)[/tex]
Apply the Difference of Two Square Formula: a²-b²=(a-b)(a+b)
[tex]\begin{aligned}\implies x^2-16&=x^2-4^2\\&=(x-4)(x+4)\end{aligned}[/tex]
Therefore:
[tex]R(x)=x(x-4)(x+4)(x+5)[/tex]
Zero Product Property
If a ⋅ b = 0 then either a = 0 or b = 0 (or both).
To find the zeros of the function, apply the zero-product property by setting each factor equal to zero and solving for x:
[tex]\implies x=0[/tex]
[tex]\implies x-4=0 \implies x=4[/tex]
[tex]\implies x+4=0 \implies x=-4[/tex]
[tex]\implies x+5=0 \implies x=-5[/tex]
Therefore, the zeros of the function R(x) are:

As per the reference document attached thereby along with the question statement, if (∠SOX = 160°), [∠1 = (x + 14)], and [∠2 = (3x – 10)], then the measure of ∠2 in degrees will be 113°
As per the reference document attached thereby along with the question statement, (∠SOX = 160°), and it's constituent angles
[∠1 = ∠SOW = (x + 14)], and [∠2 = ∠WOX = (3x – 10)],
And we are required to determine the measure of ∠2.
Since, [(∠SOW + ∠WOX) = ∠SOX],
Therefore, [{(x + 14) + (3x – 10)} = 160°]
Or, [{(x + 3x) + (14 - 10)} = 160°]
Or, [(4x - 4) = 160°]
Or, [4x = (160 + 4)°]
Or, (4x = 164°)
Or, [x = (164/4)°]
Or, (x = 41°)
Or, [(3x – 10) = {(3 * 41) - 10}°]
Or, [∠2 = (123 - 10)°]
Or, (∠2 = 113°)
That is, if (∠SOX = 160°), and it's constituent angles (∠1) and (∠2) measure as [∠1 = ∠SOW = (x + 14)], and [∠2 = ∠WOX = (3x – 10)], then the measure of ∠2 in degrees will be 113°

a fair coin is tossed five times, and each time the coin lands tails up. if the coin is then tossed 1990 more times, how many tails are most likely to appear for the 1990 additional tosses?
Probability of getting tails are most likely to appear for the 1990 additional tosses will be 1/32.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Answer: h = 19, c = 132
Step-by-step explanation:
Oooh! This is a toughie!
Okay, first of all, there's a straight line on top. A straight line is 180 degrees.
This means we have to subtract 48 from 180.
180 - 48 = 132.
This means both a and b are 132.
F is equal to 151.
180 - 151 = e
e = 29
d = 29
g = 29
132 + 29 = 161
180 - 161 = 19
h = 19
19 + 29 = 48
180 - 48 = 132
c = 132

Given:
An ostrich farmer wants to enclose a rectangular area and then divide it into six pens with fencing parallel to one side of the rectangle (see the figure below). there are 900 feet of fencing available to complete the job.
Let L and W be the length and width.
900 = L + 6W
L = 900 -6W
Area = A = LW = (900-6W)W = 900W -6W^2
A' = 990-12W = 0
W = 900/12 = 75 feet wide
L = 900 -6W = 900 - 6(75)
L = 900 - 450 = 450 feet.

The sum of all their ages is x + (x + 2) + (x + 4) + (x + 6) = 4x + 12 = 60.
Solving for x, we get 4x + 12 = 60, and subtracting 12 from both sides gives 4x = 48.
