Type a polynomial with integer coefficients and a leading coefficient of
f(x) = (Simplify your answer.)
Let p(x) be the required polynomial.
we are given that p(x) has a zero 1 with multiplicity 2
in other word, this means that (x-1) occurs twice as a factor of p(x).
How Do Polynomial Functions Work?Expressions with polynomial functions include variables with various degrees, non-zero coefficients, positive exponents (of variables), and constants. A polynomial in "b" of degree 2 is, for instance, f(b) = 4b2 - 6.
Likewise, (x-3) appears as a factor of p(x) once.
we are also given that the degree of p(x) is 3.
So, p(x) can not have more than 3 linear factors.
Altogether,
p(x) = k(x-1)^2 (x-3), where constant k ∈ R - {0}.
We may take k = 1 and get the desired polynomial,
p(x) = ( x-1)^2 ( x-3) = x^3 - 5x^2 +7x -3

The most appropriate choice for velocity and accleration will be given by- Deacceleration of a car of 15 [tex]m/s^2[/tex] is a real world situation for which the rate of change is -15
What is velocity and acceleration?
Velocity
The distance travelled by a body per unit interval of time where the direction of the motion of a body is taken into account is known as velocity.
Velocity is a vector quantity as direction of motion of body is taken into account.
If d is the displacement of body and t is the time,
Velocity = [tex]\frac{d}{t}[/tex]
Acceleration
The rate of change of velocity of a body is called acceleration.
Acceleration is a vector quantity as direction of motion of a body is taken into account.
If [tex]\Delta[/tex]v is the change of velocity and t is the time,
Acceleration = [tex]\frac{\Delta v}{t}[/tex]
If velocity decreases then it is called Deacceleration
Here
Deacceleration of a car is 15 [tex]m/s^2[/tex]
That means rate of change of velocity of a car is -15 [tex]m/s^2[/tex]
This is a real world situation for which the rate of change is -15

Explain in detail with at least two sentences how to represent the difference of z1 and z2 geometrically, given that z1= −7i and z2 = 4+3i. Then, give the difference z1 − z2 in rectangular form.
Given that z₁= −7i and z₂ = 4+3i, the difference z₁ − z₂ in rectangular form is; -4 - 10i
What is the Vector in rectangular form?Addition of complex numbers is basically the same thing as adding two-dimensional vectors that are located on the x-y Cartesian plane.
Now, it is pertinent to note that when doing vector addition, we denote the x-component with i^ and y-component with j^.
We should also not that when adding complex numbers, the x-component is the real part and y-component is the imaginary part.
Geometrically, we can say that the addition of complex numbers can be equated to the addition of vectors in x-y plane.
Thus by the the parallelogram law of vector addition, we will be able to find the resultant vector.
In rectangular coordinates,
z₁ = -7i
z₂ = 4 + 3i
Then, z₁ - z₂ = -7i - (4 + 3i)
= -7i - 4 - 3i
= -4 - 10i

The lottery's anticipated worth is $80.
Given that,
The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.
A) EV=125*.2+100*.3+50*.5=$80
The lottery's anticipated worth is $80.
The expected value is obtained by multiplying each result by its likelihood.
The expected value of the lottery is then calculated by adding up all of these.
This is what we have: ;;
125(0.2) + 100(0.3) + 50(0.5) (0.5)

What is the carpenter's net worth?
$139,450
$145,228
$281,313
$284,678
$139,450
==========================================================
Explanation:
asset = an item that is either cash or can be turned into cash
liability = something that needs to be paid back (eg: truck loan)
A = total assets
A = (homeValue) + (workEquipment) + (carValue) + (investments)
A = ( $175,742 ) + ($3,365) + ($44,346) + ($61,225)
A = $284,678
B = total liabilities
B = (mortgage)+(credit card balance)+(truck loan)
B = ($76,765)+($2,055)+($66,408)
B = $145,228
C = net worth
C = A - B
C = ($284,678) - ($145,228)
C = $139,450 which points us to choice A as the final answer.
The net worth of the carpenter is $144,633.
Given that, Home value = $175,742, Mortgage = $76,765, Credit card balance = $2,055, Owned work equipment = $3,365 and Car value = $44,346.
What is the net worth?Net worth is the value of all the non-financial and financial assets owned by an individual or institution minus the value of all its outstanding liabilities.
Here,
Net worth = Financial assets - Liabilities
= (175,742+3,365+44,346) - (76,765+2,055)
= 223,453 - 78,820
= $144,633
Therefore, the net worth of the carpenter is $144,633.

in a random sample of 45 endangered species, 12 are categorized as vulnerable, 11 are categorized as endangered, and 22 are categorized as critically endangered. what is the probability that a randomly selected species from this sample is vulnerable or critically endangered? group of answer choices
The probability that the randomly selected sample is vulnerable or critically endangered is equal to 0.76
The probability can be determined using the following formula;
probability = number of desired events or outcomes ÷ total number of events or outcomes
The total is known to be 45, the favorable or desired outcomes can be calculated as follows;
number of desired outcomes = number of vulnerable species + number of critically endangered species
number of desired outcomes = 12 + 22
number of desired outcomes = 34
Now we calculate the probability by using the above formula;
probability = 34 ÷ 45
probability = 0.76
Therefore, 0.76 is the probability that the randomly selected species is vulnerable or critically endangered.
