explain one of the theorems that you would use to find the zero of higher degree polynomial
Answers
Rational Root Theorem:
If the rational number [tex]x=\frac{b}{c}[/tex] is a zero of a higher degree polynomial:
[tex]P(x)=kx^{n}+...+m[/tex]
where all the coefficients are integers. Then [tex]b[/tex] will be a factor of [tex]m[/tex] and [tex]c[/tex] will be a factor of [tex]k[/tex]
1. Use the rational root theorem to enumerate all possible rational zeroes of the polynomial [tex]P(x)[/tex]
2. Evaluate the polynomial from the first step until you can find a zero. Let’s suppose the zero is [tex]x=r[/tex]. It will be a zero if [tex]P(r)=0[/tex]. Then if this is true, write the polynomial as:
[tex]P(x)=(x-r)Q(x)[/tex]
3. Repeat this process using [tex]Q(x)[/tex] this time rather than [tex]P(x)[/tex]. The process finishes until we reach a second degree polynomial, then solve as it is widely known for a quadratic equation.
The volume of a cuboid is 1404cm3. The length is 9cm and the width is 130mm. Work out the height of the cuboid in cm.
Answers
130mm = 13cm
Formula:
Volume = Length x Width x Height
Substitute known values into the variables:
1404 = 9 x 13 x height
1404 = 117 x height
height = 1404 ÷ 117 = 12 cm
Answer : Height = 12 cm
To calculate the height of the cuboid, we convert the width to centimeters and use the volume formula. After conversion, we find the height by dividing the volume (1404cm³) by the product of the length (9cm) and width (13cm), resulting in a height of 12cm.
To find the height of the cuboid, we can use the formula for calculating volume, which is volume = length x width x height. The question gives us the volume of the cuboid as 1404cm³, the length as 9cm, and the width as 130mm. However, we need to ensure all units are the same, so let's convert the width from millimeters to centimeters: 130mm = 13cm (since 1cm = 10mm).
Now, using the formula for volume:
Volume = length x width x height1404cm³ = 9cm x 13cm x heightTo find the height, we divide the volume by the product of the length and width:
height = Volume / (length x width)height = 1404cm³ / (9cm x 13cm)height = 1404cm³ / 117cm²height = 12cmTherefore, the height of the cuboid is 12cm.

The U-Drive Rent-A-Truck company plans to spend $15 million on 310 new vehicles. Each commercial van will cost $35 comma 000 , each small truck $70 comma 000 , and each large truck
$60 comma 000 . Past experience shows that they need twice as many vans as small trucks. How many of each type of vehicle can they buy?
Answers
x+y+z = 310 ----- (1)
But, the company will spend $15 million. Then,
35000x+ 70000y +60000z = 15,000,000
35x + 70y + 60z = 15000 ---- (2)
Additionally, twice as many van as small trucks will be required. Then,
x = 2y ---- (3).
Substituting for x in (1) and (2);
2y +y +z = 310 => 3y +z =310 ---- (4)
35(2y) + 70y + 60z = 15000 => 70y+70y+60z = 15000 => 140y + 60z = 15000 ---- (5)
Solving (4) and (5)
From (4), z = 310 -3y
Then, using (5)
140y +60(310-3y) = 15000
140y + 18600 - 180y = 15000
-40y = -3600
y = 3600/40= 90
Then, z= 310 -3y = 310 -3(90) = 310 -270 = 40
And, x = 2y = 2(90) = 180
Therefore, the number will be:
Vans (x) = 180
Small trucks (y) = 90
Large trucks (z) = 40
Set the situation up as a system of linear equations based on the information provided in the problem. Then, solve the system to get the number of each type of vehicle that the company can buy.
Explanation:To solve this problem, let's set it up as a system of linear equations. This is a mathematics problem involving problem-solving and linear equations.
Let's denote v as the number of vans, s as the number of small trucks, and l as the number of large trucks.
We know that the total money spent should equal $15 million, and we can express this as:
(35,000v) + (70,000s) + (60,000l) = 15,000,000
We also know that the number of vans is twice the number of small trucks, so we can express this as:
v = 2s
We know also that the total number of vehicles is 310, so we have:
"v + s + l = 310"
Solving these three equations will give us the number of vans, small trucks, and large trucks that the company can buy.

A ladder leans against a building. The angle of elevation of the ladder is 70°. The top of the ladder is 25 ft from the ground.
To the nearest tenth of a foot, how far from the building is the base of the ladder?
20.5 ft
30.5 ft
32.3 ft
39.5 ft
Answers
The distance from the building to the base of the ladder, when the ladder makes an angle of 70 degrees with the ground and the ladder is 25 feet long, can be calculated using the cosine function. The calculated distance is approximately 8.6 feet.
Explanation:To calculate the distance from the building to the base of the ladder, we have to use the trigonometric function cosine given the information in the problem. The cosine of an angle in a right triangle is defined as the adjacent (which is the distance we wish to find) over the hypotenuse (which is given as 25 feet).
Therefore, we write the equation as follows:
cos(70) = Adjacent/25
To find the 'Adjacent', we rearrange the equation:
Adjacent = 25*cos(70)
When you perform the calculation, you get Approximately 8.6 feet as the distance from the building to the base of the ladder.

The base of the ladder is approximately 8.5 feet from the building. This is determined using trigonometry and the cosine of the ladder's angle of elevation.
Explanation:This is a trigonometry problem where we have to find the base of the triangle formed by the ladder, the ground, and the distance from the building. The question gives us the length of the ladder (hypotenuse in the right triangle) and the angle of elevation. We can thus use cosine of the angle (base/hypotenuse) to find the base.
We know that Cosine of 70° is equal to the (base / Hypotenuse). And in the present case, the hypotenuse is given to be 25 ft.
Therefore, calculation will be as follow:
Base = Cosine (70°) * Hypotenuse.
Base = Cosine (70°) * 25 ft.
After calculating, this gives a base length of approximately 8.5 feet. So, the base of the ladder is approximately 8.5 feet from the building.

It would take an hour for plane A to meet plane B which is flying towards it. If the distance between them will be 200 miles after 45 minutes, how far apart are they now?
Answers
(Assume that the net effect of the wind is negligible.)
From the first sentence, the distance between A and B after each travels for 1 hour is a + b miles. From the second sentence, after 45 minutes, or 0.75 hour, the distance between A and B is 200 miles. Plane a has traveled 0.75a, while plane B has traveled 0.75b.
Hence a + b = 0.75a + 0.75b +200
==> 0.25(a + b) = 200.
==> a + b = 800.
Therefore planes A and B are 800 miles apart now.
Answer:
800 miles apart
Step-by-step explanation:
0.75a+0.75b=200
0.25(a+b)=200
a+b=800 miles apart

A lab worker monitors the growth of a bacteria colony starting at 9:00 a.m. At that time, there are 100 bacteria. According to the exponential function f(x) = 100(4)x, the bacteria quadruple every hour. Which equation could you use to determine the number of bacteria in the colony after 6 hours?
Answers
[tex]f(x)=100(4)^x[/tex]
[tex]f(6)=100(4)^6[/tex]
[tex]f(6)=409600[/tex]
We can conclude that the we should use the equation: [tex]f(6)=100(4)^6[/tex] to find the number of bacteria in the colony after 6 hours. Evaluating the function we get that the number is 409,600.
The equation to determine the number of bacteria in the colony after 6 hours is [tex]f(x) = 100(4)^x[/tex] and after 6 hours, there will be 409,600 bacteria in the colony.
To find the number of bacteria after 6 hours, one would substitute x with 6 in the exponential function [tex]f(x) = 100(4)^x[/tex].
This function models the growth of the bacteria colony, where the initial number of bacteria is 100 and they quadruple every hour.
The variable x represents the number of hours that have passed since the initial measurement at 9:00 a.m.
By substituting x = 6 into the function, we get:
[tex]f(6) = 100(4)^6[/tex]
Now, calculate the value of [tex](4)^6[/tex]:
[tex](4)^6 = 4 \times 4 \times 4 \times 4 \times 4 \times 4 = 4096[/tex]
Then, multiply this by the initial number of bacteria, which is 100:
f(6) = 100 [tex]\times[/tex] 4096
Finally, calculate the total number of bacteria after 6 hours:
f(6) = 409600

Answers
__,__,__,(Q1 is here)__,__,__,(median is here)__, __,__,(Q3is here)__,__,__
A. The first 3 lines are 3 pieces of data in the first quartile.
B. here are 6 pieces of data between the 1st and 3rd quartiles.
D. There are 3 pieces of data in the upper quartile.
The correct answer is C.) There are 9 pieces of data that are greater than the median. The statement that is NOT TRUE is C.) There are 9 pieces of data that are greater than the median.
To understand why option C is not true, let's review some basic concepts about quartiles and the median in a set of data:
- 3 pieces of data are less than Q1.
- 3 pieces of data are in the first quartile (Q1).
- 6 pieces of data are between Q1 and Q3 (the interquartile range, IQR).
- 3 pieces of data are in the third quartile (Q3).
- Including the median itself, 4 pieces of data are greater than or equal to the median.
This breakdown correctly accounts for all 12 pieces of data. As a result, the statement that is NOT TRUE is indeed option C:
C.) There are 9 pieces of data that are greater than the median.
Since there are 4 pieces of data that are greater than or equal to the median, option C, which asserts there are 9 such pieces, is false. The correct understanding aligns with your analysis of quartiles and the median in this dataset.
