Complete the first row of the synthetic division table.
The expression x - 4 is a factor of the polynomial f(x) = 4x³ - 21x² + 26x - 24 as f(4) = 0. And (x - 4)(4x² - 5x + 6) is the product of two factors for f(x).
The factor theorem in polynomialThe factor theorem states that: if f(x) is divisible by x - a if and only if f(a)=0.
We shall evaluate f(4) to know if x - 4 is a factor of the polynomial f(x) as follows;
f(4) = 4(4)³ - 21(4)² +26(4) - 24
f(4) = 256 - 336 + 104 - 24
f(4) = 360 - 360
f(4) = 0
The first row of the synthetic division is derived as follows:
4x³ divided by x equals 4x²
x - 4 multiplied by 4x² equals 4x³ - 16x²
subtract 4x³ - 16x² from 4x³ - 21x² + 26x - 24 will result to -5x² + 26x - 24

Jack's maximum and minimum time to fold his laundry is |x - 30| = 10: option is D.
How to illustrate the equation?Remember that the statement says Jack's time can vary from the average of 30 minutes by 10 minutes. By implication it means that the maximum and minimum time will be 30 minutes plus or minus 10 minutes, or 40 minutes and 20 minutes, respectively. We can represent these values using the variable x.
The maximum time will be represented by x + 10 and the minimum time will be represented by x - 10. We can use the absolute value function to represent the difference between these two values and the average time of 30 minutes.
The absolute value function is represented as |x|. The absolute value of x is the distance between x and 0 on a number line. For example, the absolute value of -5 is 5, because the distance between -5 and 0 on a number line is 5 units.
Using the absolute value function, we can represent the difference between the maximum and minimum times and the average time of 30 minutes as follows:
|x + 10 - 30| = |x - 30| = 10
|x - 20| = 10
|x - 30| = 10

The enrollment of the school each year after 2000 is a linear function and the equation is f(x) = 1200 + 35x
How to describe the enrolmentFrom the question, we have the following parameters that can be used in our computation:
Initial number of students = 1200
Rate of student per year = 35
The above parameters implies that there is a constant increment of 35 students each year since 2000
This means that the scenario is a linear equation
A linear equation is represented as
y = mx + c
In this case, we have
c = Initial number of students = 1200
m = Rate of student per year = 35
Substitute the known values in the above equation, so, we have the following representation
y = 35x + 1200

The critical value for the test would be +/- 1.984
The critical value for a two-tailed t-test with a significance level of 0.05 and degrees of freedom of 99 is the value beyond which we can reject the null hypothesis. This means that if the test statistic (t-value) is greater than or less than this critical value, we can conclude that the null hypothesis is not true and the alternative hypothesis is more likely to be true.
To find the critical value, we can use a t-distribution table or a calculator with t-test functionality. We input the desired significance level (0.05), the degrees of freedom (99), and the type of test (two-tailed). The resulting value is the critical value for this test.
In this case, the critical value for the test would be +/- 1.984. This means that if the t-value calculated from the sample data is greater than 1.984 or less than -1.984, we can reject the null hypothesis and conclude that the mean foam height is not equal to 175 mm. If the t-value is between these two values, we cannot reject the null hypothesis and cannot conclude that the mean foam height is different from 175 mm.

Answer: The graph shows no correlation, and it is neither linear nor exponential.
Step-by-step explanation:
try doing a line of fit you're ALWAYS. gonna be ignoring other dots/points/coorids.
Why it's not a correlation is because nothing is together. You could consider a lot of dots on the edge.
If that doesn't make sense to you lets go through each answer
The graph shows a negative correlation, and it is a linear model.
The coordinates don't form any specific line
None of the coordinates are together
there's no slope since there's no line of fit.

Dry concrete can be made by mixing sand gravel and cement. The ratio of 1:2:4 if you want 14,000 kg of dry concrete how much would you need?
Step-by-step explanation:
Add up 1,2,4 which is 7. Then do 14,000/7 which gives you 2,000kg. Then multiply the 2,000kg with each number in the ratio. It can be tricky to grasp this method at first, but believe me when I say that after practice it becomes almost second nature.
Answer:
2,000kg X 1 = 2,000kg
2,000kg X 2 = 4,000kg
2,000kg X 4 = 8,000kg
2,000kg X 1 = 2,000kg
2,000kg X 2 = 4,000kg
2,000kg X 4 = 8,000kg

Step-by-step explanation:
214,000,000
+ 907,000
Answer:
Answer Below
Step-by-step explanation:
Let us take the variables as x,x+1
x+x+1 = 214907000
2x+1 = 214907000
2x = 214906999
x = [tex]\frac{214906999}{2}[/tex]
x = 107453499.5
1st number = x = 107453499.5
2nd number = x + 1 = 107453499.5 + 1 =107453500.5
Hence , the number that need to be added to get 214,907,000 are 107453499.5 and 107453500.5
Write an equation in the form y=mx+b. Then solve each problem.
1. A contractor's crew can frame 3 houses in week. how long will it take them to frame54 houses if they frame the same number each week?
2. A water tank holds 18,000 gallons. How long will it take for the water level to reach 6000 gallons if the water is used at an average rate of 450 gallons per day?
Answer:
1) y = 3x + 0
54 houses = 3 houses/week * x weeks
x = 18 weeks
2) y = -450x + 18000
6000 gallons = -450 gallons/day * x days + 18000
x = 10 days
A company can choose to package 12 cans into 3rows of 4 or in rows 6 rows of 2 which packaging uses more material? Why would a company choose to package 12 cans one way instead of another
The packaging that will use more material would be the 6 rows in 2.
What is packaging?Packaging is a method used by companies to present a finished product to the population in such a way that their products can be easily accessed.
The first choice of packaging= 3 rows in 4 which means that it's only three packages that would be used.
The second choice of packaging = 6 rows in 2 which means that it's up to six packages that would be used.
Therefore, it would be better for the company to chose the 3 rows in 4 which is the first choice as it will save up materials for them.

find the gradient vector field ∇f of f and sketch it. f(x, y) = x2 − 5y
The gradient vector field ∇f of f(x,y) = x^2 -5y is <2x, -5>
The gradient vector field is a vector-valued function that is used to describe the direction of the steepest ascent of a scalar field. The gradient vector field of a scalar field f is given by ∇f = <∂f/∂x, ∂f/∂y>
In this case, the gradient vector field of f(x, y) = x^2 − 5y is <2x, -5>.
To sketch the gradient vector field, we can start by plotting a few points on the x-y plane and then drawing the gradient vector at each point.
For example, the gradient vector at the point (1,0) is <2, -5>; at the point (0,1) is <0, -5>; at the point (-1, 0) is <-2, -5>; at the point (0, -1) is <0, -5>.
The vector field will be pointing towards the direction where the function increase the most, in this case, the vector field will be pointing upwards and to the right in the x-y plane.

Emma is training for a 10-kilometer race. She wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. Emma has already run for 55 minutes. Which inequality can be used to find how much longer she can run and still beat her previous time
The inequality 1.10 < 1+ (55/60) can be used to find how much longer Emma can run and still beat her previous time. This inequality is formed by taking her previous 10-kilometer time of 1 hour and 10 minutes and adding the number of minutes she has already run (55 minutes) divided by 60. If the result is greater than 1.10, she will beat her previous time.
1.10 < 1 + (55/60)
1.10 < 1.9166667
0.79166667 < 0.9166667
Therefore, Emma can run for up to 0.79166667 more hours and still beat her previous time.
The inequality 1.10 < 1+ (55/60) can be used to find how much longer Emma can run and still beat her previous time. This inequality is formed by taking her previous 10-kilometer time of 1 hour and 10 minutes and adding the number of minutes she has already run (55 minutes) divided by 60. The equation can be written as
1.10 < 1+(55/60).
If the result is greater than 1.10, she will beat her previous time. To calculate, we first divide 55 minutes by 60 to get 0.91666667 and then add 1 to get 1.91666667. We then compare this value to 1.10 and see that 1.10 is less than 1.91666667, so Emma can run for up to 0.79166667 more hours and still beat her previous time. This is equivalent to 47 minutes. Therefore, if Emma runs for a total of 1 hour and 42 minutes, she should beat her previous time.

J(2,-4),K(3,7),L(6,-1) reflection over x-axis
To reflect a point over the x-axis, we need to negate the y-coordinate. So the reflections of points J, K, and L over the x-axis are:
J'(2,4)
K'(3,-7)
L'(6,1)
Note that the x-coordinates are unchanged because the x-axis is the line of reflection.
