Answer:
(x - 3) is not a factor
Step-by-step explanation:
If (x - h) is a factor of f(x) then f(h) = 0
here
f(x) = x³ - 5x² - 4x + 6 , then
f(3) = 3³ - 5(3)² - 4(3) + 6 = 27 - 5(9) - 12 + 6 = 27 - 45 - 6 = - 24
since f(x) ≠ 0 then (x - 3) is not a factor of f(x)

Identify a value of k that transforms f into g, where g(x) = f(x) + k.
Answer:
The transformation that maps f into g is a translation transformation,
involving the addition of k to the value of f(x).
The value of k that transforms f into g is; k = -5
Reasons:
Points on the graph of g(x) are; (0, -3) and (0, 1)
The equation of g(x) is; y - (-3) = 4·x, which gives;
y = 4·x - 3
The y-intercept = -3
Points on the graph of f(x) are; (-1 -2) and (0, 2)
The equation of f(x) is; y - (-2) = 4·(x - (-1)), which gives;
y = 4·x + 4 - 2 = 4·x + 2
The y-intercept = 2
The slopes of the graphs of f(x) and g(x) are equal, therefore, f(x) ║ g(x)
The difference or the transformation that takes the y-intercept of f(x) to the
y-intercept of g(x) is; k = y-intercept(g(x)) - y-intercept(f(x)) = -3 - 2 = -5
Therefore, k = -5
Which gives;
g(x) = f(x) - 5
The value of k that transforms f into g is; k = -5

A movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total cost for a reward program member to see 5 movies is $40 and the total cost for 12 movies is $75. Assume the relationship is linear. Write the equation of the function in the form y=mx+b , where x represents the number of movies and y represents the total cost.
Hint: Treat this information like ordered pairs. (5, 40) and (12, 75)
Answer:
[tex]y=5x+15[/tex]
Step-by-step explanation:
Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs [tex](x_1,y_1)\rightarrow(5,40)[/tex] and [tex](x_2,y_2)\rightarrow(12,75)[/tex]:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5[/tex]
Thus, our equation so far is [tex]y=5x+b[/tex]. Next, we need to find our y-intercept, [tex]b[/tex], which represents our flat fee. We do so by using one of our original given ordered pairs:
[tex]y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b[/tex]
Therefore, our final equation for the function is [tex]y=5x+15[/tex]

Answer:
Option C is correctThe initial value of the exponential function shown on the graph is, 2Step-by-step explanation:A function is a mathematical relation in which we input values of a domain that generate output values of a range. Initial value of a function is the output value of the function when the input value is 0.As shown in the graph: the exponential function cut through the point (0,2) , where y=2 when x=0.therefore, the initial value of the given exponential function shown on the graph is, 2.

Answer:
Surface Area = [tex]530yd^2[/tex]
Step-by-step explanation:
*This answer is for the problem on the left that seems unanswered*
Firstly, you must understand that the surface area of an irregular polygon like the one in the problem must be found by dividing its faces into rectangles and finding the sum of the areas of those rectangles.
Another way to say this is that the surface areas of these solids can be found by adding up the areas of the rectangles that make their faces.
You will see that I attached a picture that divides the solid's faces into subsections, labelled a through i, including faces that are not visible in the diagram.
If you divided the solid's faces in the same way as the picture, the surface area is found as follows:
[tex]Area_A=12*7=84yd^2\\Area_B=12*4=48yd^2\\Area_C=12*4=48yd^2\\Area_D=4*4=16yd^2\\Area_E=11*3=33yd^2\\Area_F=12*3=36yd^2\\Area_G(notVisible)=12*11=132yd^2\\Area_H(notVisible)=12*7=84yd^2\\Area_I(notVisible)=Area_E+Area_D=33+16=49yd^2[/tex]
By the way, [tex]yd^{2}[/tex] is the same as "square yards".
After finding the areas of each rectangle, add them all up to get your final answer:
[tex]SurfaceArea=530yd^2[/tex]

Question: Quadrilateral GABE is a square. Assume that point A is the centre of the circle. If the circumference (perimeter of a circle) is 201 ft., find AE.
Solution:
πd = C
πd = 201
3.14(d) = 201
diameter = 64.01
radius is half of the diameter.
radius = 64.01/2
radius = 32
GA = 32
As its sqaure, all sides are equal
GA = AB = GE = EB = 32
using Pythagoras theorem:
32² + 32² = AE²
AE = √2048.8
AE = 45.3 ft
Answer:
Step-by-step explanation:
C = πd = 2πr
201 = 2*3.14*AB
AB = 201 / (2*3.14) = 32
AE is the diagonal of square ABEG
Using Pythagoras theorem,
AE^2 = AB^2 + BE^2 = 2*AB^2
AE^2 = 2*32^2
AE = sqrt(2*32^2)
= 45.255
= 45.3 ft

the price of a coffee increases to £3.37 by 7%. how much was it for a coffee before the increase?
Answer:
£3.15 (nearest pence)
Step-by-step explanation:
If the price of a coffee has increased by 7% then the final price of the coffee is: 100% + 7% = 107% of the original price.
Therefore, to find the original price of the coffee:
original price ÷ 107 × 100
= 3.37 ÷ 107 × 100
= £3.15 (nearest pence)
A parallel line has a y-intercept of 12.
Write down the equation of this line.
Answer:
Using the equation form y = MX + b where a is the slope of the line and b is the y-intercept.
The line that is parallel this the line with equation 5x + y = 11 will have the SAME SLOPE as this line BUT the y-intercept will be -8 (as stated in the problem.)
Rewrite 5x + y = 11 to the standard form to yield the slope of that line.
So 5x + y = 11 becomes y = -5x + 11 where the slope is -5.
So the equation of the line that you want is then...y = -5x - 8. It satisfies both conditions.

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes. Let µ represent the average number of minutes to fill an order. Z = StartFraction x overbar minus mu Over (StartFraction sigma Over StartRoot n EndRoot EndFraction) EndFraction To the nearest hundredth, the z-statistic is z =.
By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19
What is standard deviation?Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value

Barbara used the distributive property to write an expression that is equivalent to 7 d 63. Her work is shown below. The greatest common factor is 7 so 7 d 63 = 7 (d 63) What was Barbara’s error? Barbara wrote (d 63) instead of 63 d). Barbara wrote (d 63) instead of (d 9). Barbara wrote (d 63) instead of (d 56). Barbara wrote (d 63) instead of (10 d).
The error that Barbara's made is that Barbara wrote (d+63) instead of (d+9).
What is Distributive property?The distributive property of multiplication is that when two numbers are added such as (a+b) and multiplied by a third number such as x, then the result will be the sum of multiplication of the third number with the first number (xa) and the third number with the second number (xb).
x(a+b) = xa + xb,
