Step-by-step explanation:
If we have a function,
[tex]f(x)[/tex]
We can rotate the function across the x axis using the rule
[tex] - f(x)[/tex]
So we have function
[tex]f(x) = 4 {x}^{3} - 3 {x}^{2} + 8x - 6[/tex]
[tex]f(x) = - ( {4x}^{3} - 3 {x}^{2} + 8x - 6)[/tex]
[tex]f(x) = - 4x {}^{3} + 3 {x}^{2} - 8x + 6[/tex]

An airplane left Chicago at 9:50 AM Central Time and arrived in Memphis at 11:30 AM Central Time. How long did the flight take
Considering that both Chicago and Memphis are in the same time zone, the flight took one hour and 40 minutes.
What was the length of the flight?It Chicago at 9:50 AM Central Time and arrived in Memphis at 11:30 AM Central Time. Since they are in the same time zone, we don't have to do anything but subtract, then:
11:30 - 9:50
30 < 50, hence we remove one hour from Memphis and add 60 minutes, thus:
10:90 - 9:50 = 1:40
The flight took one hour and 40 minutes.

Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability. (Round your answer to four decimal places.)
= 8; = 6
P(5 ≤ x ≤ 17) =
Using the normal distribution, it is found that P(5 ≤ x ≤ 17) = 0.6247.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, we are given that [tex]\mu = 8, \sigma = 6[/tex].
The probability is the p-value of Z when X = 17 subtracted by the p-value of Z when X = 5, hence:
X = 17:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{17 - 8}{6}[/tex]
[tex]Z = 1.5[/tex]
[tex]Z = 1.5[/tex] has a p-value of 0.9332.
X = 5:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{5 - 8}{6}[/tex]
[tex]Z = -0.5[/tex]
[tex]Z = -0.5[/tex] has a p-value of 0.3085.
0.9332 - 0.3085 = 0.6247.
Hence, P(5 ≤ x ≤ 17) = 0.6247.

find the area of the given quadrilateral
Answer:
250m^2
Step-by-step explanation:
Area of quadrilateral = ½ × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices
We can substitute the numbers given into the formula shown above.
1/2 * 25 * (8+12)m^2
This can be simplified to 1/2 * 25 * 20 which is 250m squared

Answer:
We can first determine it is not A or C, because these flatly do not equal the expression above.
I believe is it D, because of the commutative property.
The associative property of addition states that you can group the addends in different ways without changing the outcome. While the commutative property of addition states that you can reorder the addends without changing the outcome.
In this case, we are rearranging the addends, not groups of them.
Step-by-step explanation:
a. Find the slope of the line that passes through the points (2,-5) and (-2,3).
b. What are the slope and y-intercept of the equation 2x - 5y = -10?
c. Find the x value so that the line through the points (x,-9) and (0,1) has a slope of -4.
d. Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b.
PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.

Bill and Felicia both bake cookies for a party. Bill bakes 3 times as many as Felicia. Felicia bakes 24 fewer cookies than Bill. Bill bakes b cookies and Felicia bakes f cookies. What pair of equations can be used to determine the number of cookies Bill and Felicia bake?
A. b = 3f
f = b - 24
B. b = 3(f + 24)
f = b - 24
C. b = 3f
f = 24 - b
D. f = 3b
b = f - 24
PLEASE HELP ♡
Answer: Below
Step-by-step explanation:
So we start off with b and f. Our first piece of information, Bill baked 3 times as many as Felicia, gives us the equation:
b = 3f
The second piece gives us the equation:
b = f + 24
We have a 3f, but no b = f + 24 in the possible answers. So:
b = f +24
b - 24 = f
Our answer is A.
Write an equation in slope-intercept form for the following line:
(-17,-4) and (-7,-13)
Linear equations are often organized in slope-intercept form:
[tex]y=mx+b[/tex]
(x,y) = a point that falls on the linem = the slope of the lineb = the y-intercept of the lineSlope (m)The slope of a line is equal to its [tex]\dfrac{rise}{run}[/tex].
"Rise" refers to the number of units the line travels up."Run" refers to the number of units the line travels to the right.Typically, we would solve for the slope by using the following formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]Y-intercept (b)The y-intercept of a line refers to the y-value that occurs when x=0.
On a graph, it is the y-value where the line crosses the y-axis.
Writing the Equation1) Determine the slope of the line (m)
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the two given points, (-17,-4) and (-7,-13):
[tex]m=\dfrac{-13-(-4)}{(-7)-(-17)}\\\\m=\dfrac{-13+4}{-7+17}\\\\m=\dfrac{-9}{10}[/tex]
Therefore, the slope of the line is [tex]-\dfrac{9}{10}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-\dfrac{9}{10}x+b[/tex]
2) Determining the y-intercept (b)
[tex]y=-\dfrac{9}{10}x+b[/tex]
Plug in one of the given points and solve for b:
[tex]-4=-\dfrac{9}{10}(-17)+b\\\\-4=\dfrac{153}{10}+b\\\\b=-\dfrac{193}{10}[/tex]
Therefore, the y-intercept of the line is [tex]-\dfrac{193}{10}[/tex]. Plug this back into our equation:
[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]
Answer[tex]y=-\dfrac{9}{10}x-\dfrac{193}{10}[/tex]
