The equation of the polynomial is P(x) = 1/27(x + 3)(x + 2)(x - 1)(x - 3)^2
How to determine the equation of the polynomialFrom the question, we have the following parameters that can be used in our computation:
The graph
On the graph, we have the following readings:
A root of multiplicity 1 at x = -3 A root of multiplicity 1 at x = -2A root of multiplicity 1 at x = 1A root of multiplicity 2 at x = 3y-intercept = 2A polynomial is represented as
P(x) = a * (x - zero)^multiplicity
Using the above as a guide, we have the following:
P(x) = a * (x + 3)(x + 2)(x - 1)(x - 3)^2
The y-intercept is 2
So, we have
a * (0 + 3)(0 + 2)(0 - 1)(0 - 3)^2 = 2
This gives
a = -1/27
Hence, the expression is P(x) = 1/27(x + 3)(x + 2)(x - 1)(x - 3)^2

Last year Kristen had $ 20 , 000 to invest. She invested some of it in the first account that paid 7 % simple interest per year, and she invested the rest of it in a second account that paid 8 % simple interest per year. After one year, she received a total of $ 1 , 540 in interest. How much did she invest in each account?
Answers
The amount invested in the account that earns 7% interest is $6,000 and the amount invested in the account that earns 8% interest is $14,000.
How much is invested in each account?The system of equations that represent the information in the question is:
a + b = 20,000 equation 1
0.07a + 0.08b = 1540 equation 2
Where:
a = amount invested in the account that earns 7% interest
b = amount invested in the account that earns 8% interest
The elimination method would be used to solve the equations.
Multiply equation 1 by 0.07
0.07a + 0.07b = 1,400 equation 3
Subtract equation 3 from equation 2
0.01b = 140
Divide both sides of the equation by 0.01
b = 140/ 0.01
b = 14,000
Substitute for b in equation 1:
a + 14,000 = 20,000
a = 20,000 - 14,000
a = 6,000

In the critical value method, we find the area in the tail end and compare it to alpha to determine whether to reject or fail to reject the null hypothesis.
Answers
The critical value strategy entails deciding whether or not the observed test statistic is more extreme than would be anticipated if the null hypothesis were true in order to determine whether something is "likely" or "unlikely."
How do you determine the rejection zone and the crucial value?
The rejection zone is the area in which we have sufficient data to reject the null hypothesis if our test statistic falls within it. The rejection area, for the right-tailed test, for instance, is any value bigger than the critical value, or c 1 .
To execute any hypothesis test, the critical value technique entails four specific phases, which are as follows:
The null and alternative hypotheses should be specified.Calculate using the sample data and the null hypothesis as the default. the test statistic's value Using the t-statistic t=m−μ÷s/√n which follows a t-distribution with n - 1 degrees of freedom, we may test the population mean hypothesis.By determining the value of the known distribution of the test statistic such that the likelihood of making a Type I mistake is low, also known as the "significance level of the test," or (greek letter "alpha"), the crucial value can be found (typically 0.01, 0.05, or 0.10).Assess the critical value against the test statistic.

The linear equation that passes through the two given points is:
y = (5/8)*x + 19/8
How to write the linear equation?We want to find the equation of a line that passes through (1, 3) and (9, 8).
Remember that the slope of a line that passes through two points (x₁, y₁) and (x₂, y₂) is given by the equation:
slope = (y₂ - y₁)/(x₂ - x₁)
Here we know the two points (1, 3) and (9, 8).
Then the slope is:
slope = (8 - 3)/(9 - 1) = 5/8
We can write the line as:
y = (5/8)*x + b
To find the value of b,we can evaluate in one of the given points, for example, if we use (1, 3) then we will get:

When solving similar triangles, you must set up a proportion. We do not know what the other two lengths are for side AB, but we can still solve another way. For side AC, we can set up a proportion of 33/44. We're going to take AM and put that over the total. The total length of side AB is 24, and we're going to use x for AL.
33/44 = x/24
Once finished solving the proportion, you are left with 18
The missing length of triangle is 18.
What exactly is a triangle?
Triangles are polygons in geometry that have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.
A triangle is categorised into three categories based on its sides, namely:
Scalene Triangle - Each side has a distinct length.Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.Equilateral Triangle - A triangle has three sides that are of the same length.A triangle is categorised into three categories based on its angles, namely:
Acute Angle Triangle - A triangle with all of its angles smaller than 90°.Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.Triangle with a Right Angle - A triangle with one of its angles equal to 90°.Now,
As these triangles are similar that means
we can find the proportion of sides from given sides and
from that find x.
So, here AC/AM=AL/AB

Find the area of rectangle PLUMP

Answers
Step-by-step explanation:
we need to remember 2 things for right-angled triangles (which we need to use to find the sides of the rectangle, so that we then can calculate the area) :
1. Pythagoras
a² + b² = c²
with c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs.
2. geometric mean theorem
height = sqrt(p×q)
with p and q being the segments of the baseline the height is splitting it into. in our case MA and AL.
so, to get the length of the rectangle (PL) we use Pythagoras :
PL² = 6² + 8² = 36 + 64 = 100
PL = 10 units
to get PM we first need to get ML. and for that we need to get MA.
6 = sqrt(MA × 8)
36 = MA × 8
MA = 36/8 = 4.5 units
that means ML = 8 + 4.5 = 12.5 units
and again Pythagoras
ML² = PL² + PM²
12.5² = 10² + PM²
156.25 = 100 + PM²
56.25 = PM²
PM = 7.5 = 7.5 units
so, the area of the rectangle is
10 × 7.5 = 75 = 75.00 units²

Calculate the total number of water loads that were supplied to the project on the constitution site by the water tanker in March 2022
Answers
Note that in order to solve the above, we had to assume a start date for the construction. Hence, by March 2022, a total number of liters supplied is 3,380,000 liters.
What is the rationale for the above response?
To solve the problem, we need to know how many weekdays are in March 2022. March 2022 has 23 weekdays (31 days - 4 Saturdays - 4 Sundays).
Since the company has to supply a minimum of 12 water tankers and a maximum of 16 water tankers to the construction site on weekdays, we can assume an average of 14 water tankers per weekday. Therefore, the total number of water tankers to be supplied on weekdays in March 2022 would be:
14 water tankers/day x 23 weekdays = 322 water tankers
On Saturdays, the company has to supply a minimum of 4 water tankers. Since there are 4 Saturdays in March 2022, the total number of water tankers to be supplied on Saturdays in March 2022 would be:
4 water tankers/day x 4 Saturdays = 16 water tankers
Therefore, the total number of water tankers to be supplied in March 2022 would be:
322 water tankers (weekdays) + 16 water tankers (Saturdays) = 338 water tankers.
Assuming each water tanker carries a load of 10,000 liters, the total volume of water supplied to the construction site in March 2022 would be:

The figure below shows a rope that circles the Earth. The radius of the Earth is
6371
63716371 kilometers.
Assuming the rope makes a perfect circle, what is the length of this rope?
Give your answer in terms of pi.
Answers
Answer:
The circumference of a circle can be calculated using the formula:
Circumference = 2πr
Where r is the radius of the circle.
Plugging in the value for the radius of the Earth, we have:
Circumference = 2π(6371 km) = 12,742 km
So the length of the rope, assuming it makes a perfect circle around the Earth, would be 12,742 km = 2π(6371) kilometers.
Step-by-step explanation:
18 What is the solution to the system of equations x - y = -1 and x-3y = - 13?
A. (5, 6)
B.
(6,5)
C. (7,8)
D.
(8,7)
Answers
Using elimination, subtract EQ.2 from EQ.1
When we subtract, we change the sign of EQ.2 and add
x - y = -1 Equation 1
- (x - 3y = -13) Equation 2
x - y = -1 Equation 1
-x + 3y = 13 Equation 2
__________
2y = 12
Divide both sides by 2 to solve
2/2 y = 12/2
y = 6
Substitute y value of 6 into EQ.1
x -6 = -1
Add 6 to both sides to solve for x
x -6 +6 = -1 +6
Simplify
x = 5
Solution: ( 5, 6 )
A 10-ft board is cut into 2 pieces so that one piece of 6 feet longer than 3 times the shorter piece. If the shorter piece is x feet long find the lengths of both pieces
Answers
The lengths of the pieces are 1ft and 9ft
How to determine the length of sides
From the information given, we have that;
The shorter side = x
The longer side of the board = 6 +3x
The total length = 10
Substitute the values, we have;
x + 6 + 3x = 10
collect the like terms
x + 3x = 10 -6
Add or substract the like terms, we have;
4x = 4
Now, make 'x' the subject of formula by dividing by 4, we get;
4x/4 = 4/4
x = 1 ft
The longer side = 9ft
Hence, the values are 1 and 9
