To identify high-paying jobs for people that do not like stress, the following data were collected showing the average annual salary ($1000) and the stress tolerance for a variety of occupations (Business Insider, November 8, 2013). The stress tolerance for each job is rated on a scale from 0 to 100, where a lower rating indicates less stress.

Answer:
First point: -4 on y axis.
Second point: (2, -5)
Step-by-step explanation:
When graphing, we always set the equation as y=mx+b where m = slope and b = y intercept
y = mx + b
y = [tex]-\frac{1}{2}x-4[/tex]
Then we plot by starting with the y intercept going four units down, one unit below and two units to the right.
If f(x)=x^3−5x^2−2x+24 and (x+2) is a factor, what are the remaining factors?
Factor 1:
Factor 2:
Factor 3:
Answer:
(x+2), (x-4), (x-3)
Step-by-step explanation:
Use the rational root theorem to get started, then factor the remaining quadratic to find:
x^3 − 5x^2 − 2x + 24 = (x + 2)(x − 4)(x − 3)
Explanation:
Let f(x) =x^3 − 5x^2 − 2x + 24
By the rational root theorem, any rational zeros of f(x) must be expressible in the for p/q for integers p, q with p a divisor of the constant term 24 and q a divisor of the coefficient 1 of the leading term.
That means that the only possible rational zeros are the factors of 24, namely:
± 1, ± 2, ± 3, ± 4, ± 6, ± 12, ± 24
Try each in turn:
f(1) = 1 − 5 − 2 + 24 = 18
f(−1) = −1 − 5 + 2 + 24 = 20
f(2) = 8 − 20 − 4 + 24 = 8
f(−2) = −8 − 20 + 4 + 24 = 0
So x = −2 is a zero and (x + 2) is a factor.
x^3 − 5x^2 − 2x + 24 = (x + 2)(x^2 − 7x + 12)
We can factor
x^2 − 7x + 12 by noting that 4 × 3 = 12 and 4 + 3 = 7, so:
x^2 − 7x + 12 = (x − 4)(x − 3)
Putting it all together:
x^3 − 5x^2 − 2x + 24 = (x + 2)(x − 4)(x − 3)
What is the midline of this function? y=
What is the amplitude of this function? Define a function, g, to represent the behavior of the graphed function. g(a)=
NO LINKS.
Answer:
Midline is at y = 0
Amplitude is; A = 1.5
g(a) = 1.5 sin 0.5x
Period = 4π
Max value; y = 1.5
Min value; y = -1.5
Step-by-step explanation:
From the graph, we know that amplitude is highest point of the graph which is 1.5.
Thus, A = 1.5
Now,period from the graph is distance between where the graph repeats which in this case is 2π + 2π = 4π
Now, equation of this curve is;
y = A sin(B(x + C)) + D
Where;
A is amplitude
B is 2π/period = 2π/4π = ½
C is phase shift
D is vertical shift
The function g(a) that will represent the behavior of the graphed function would be gotten by Plugging in the relevant values but in this case, there are no phase shifts or vertical shifts. Thus, C = D = 0
g(a) = 1.5 sin 0.5x
Midline is the point between the maximum and minimum values.
Max value is at y = 1.5
Min value is at y = -1.5
Midline of both from the graph is at x = -π/2 which is at y = 0
is this true or false
Answer:
False

You spend some time in the kitchen making sure the recipe is just right for
the cooking show. You spend 2 3/4 hours baking and half of an hour
cleaning up the kitchen. How much time were you in the kitchen?
Answer: 3¼ hours
Step-by-step explanation:
Number of hours used in baking = 2¾ hours
Number of hours used in cleaning up the kitchen = ½ hour
Therefore, the time used in the kitchen will be the addition of the time used in baking plus the time used in cleaning the kitchen which will be:
= 2¾ + ½
= 2 3/4 + 2/4
= 2 5/4
= 2 + 1¼
= 3¼ hours
Therefore, 3¼ hours was used in the kitchen.

Answer:
thers no question
Step-by-step explanation:
A tank contains 40 gallons of a solution composed of water and bleach. At the start there are 4 gallons of bleach in the tank. A second solution containing half water and half bleach is added tothe tank at the rate of 4 gallons per minute. The solution is kept throughly mixed and drains from the tank at the rate of 4 gallons per minute.
(a) How much blcach is in the tank after t minutes?
(b) Will there be at least 14 gallons of bleach in the tank after 10 minutes?
(c) How much bleach will there be in the tank after a very long time has passed?
Answer:
a) x* e∧ t/10 = 20 *e∧ t/10 + 2
b) x = 14,2 gall. In 10 min. we get 14,2 gallons of bleach in the tank
c) After a very long time we will find 20 gallons of bleach in the tank
Step-by-step explanation:
The variation of bleach in water in the tank is Δ(x)t:
Δ(x)t = [Amount of x added to the tank - Amount of x drain out of the tank]*Δt
Now the amount of x added to the tank is:
Rate of adding* the concentration
Rate of adding = 4 gallons per minute
Concentration half and half ( water + bleach) = 0,5
Rate of draining = 4 gallons per minute
Concentration of draining: Unknown but can be expressed as:
x(t)/40. According to this
Δ(x)t = [4 * 0,5 - 4 * x(t)/40]*Δt
Dividing by Δt on both sides of the equation and tacking limits we get
dx/ dt = 2 - x / 10
dx/dt + x/10 =2
Multyiplying by e∧ t/10 on both sides
e∧ t/10* [ dx/dt + x/10 ] = 2 *e∧ t/10
To solve it, integrating the first member is
x* e∧ t/10 = 20 *e∧ t/10 + C
for initial condition t = 0
4 = 20 + C
C = -16
a) x* e∧ t/10 = 20 *e∧ t/10 - 16
b) in 10 minutes
x* e∧ t/10 = 20 *e∧ t/10 - 16
x *e = 20*e - 16
x = 20 - 16/e
x = 20 - 16/2,718
x = 20 - 5,88
x = 14,2 gallons.
c) After a very long time we will find 20 gallons of bleach in the tank

If f(x) = x2, and
g(x) = x – 1, then
g(f(x)) = x[? ] +[ ]
Answer:
[tex]g(f(x)) = x^{[2]} +[-1][/tex]
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) =x -1[/tex]
Required
[tex]g(f(x))[/tex]
We have:
[tex]g(x) =x -1[/tex]
Replace x with f(x):
[tex]g(f(x)) = f(x) -1[/tex]
Substitute [tex]f(x) = x^2[/tex]
[tex]g(f(x)) = x^2 -1[/tex]
Hence:
[tex]g(f(x)) = x^{[2]} +[-1][/tex]

- 10; for y.
Answer:
[tex]y=80-\frac{8x}{7}[/tex]
Step-by-step explanation:
15). Given equation is,
[tex]\frac{x}{7}+ \frac{y}{8}=10[/tex]
Multiply the equation by 8,
[tex]8(\frac{x}{7}+ \frac{y}{8})=10\times 8[/tex]
[tex]\frac{8x}{7}+y=80[/tex]
Subtract [tex]\frac{8x}{7}[/tex] from both the sides of the equation,
[tex]\frac{8x}{7}+y-\frac{8x}{7}=80-\frac{8x}{7}[/tex]
[tex]y=80-\frac{8x}{7}[/tex]
Therefore, value of the variable 'y' will be,
[tex]y=80-\frac{8x}{7}[/tex]

Find the area of the regular polygon with the given apothem a and side length s.
pentagon, a = 12.4 cm, s = 18 cm
The area is
cm2
Answer:
496 cm²
Step-by-step explanation:
Area of polygon :
A = 1/2(p * a)
P = perimeter
a = apothem
Perimeter = 5s (pentagon)
s = side length = 18
P = 5 * 18 = 80 cm
a = 12.4
A = 1/2(80 * 12.4)
A = 1/2(992)
A = 496 cm²

A study has been done to determine to see if the level of education determines how often people move between different states in America.

No High School Diploma 6 2 8
High School Diploma 14 16 30
College Degree 2 18 20
Total 22 36 58
Options;
a) 0.111
b) 0.310
c) 0.500
d) 0.900
Answer:
The required probability is 0.9
Option d) 0.900 is the correct answer.
Step-by-step explanation:'
Given the data in the question;
Total number of people in the survey or sample size n = 58
Number of people with college degree who live in 2 or more state = 18
P(2 states or more and college degree) = Number of people with college degree who live in 2 or more state / Total number of people in the survey
P(2 states or more and college degree) = 18 / 58
Also, Total number of people with college degree = 2 + 18 = 20
so, P( College Degree ) = Total number of people with college degree / Total number of people in the survey
P( College Degree ) = 20 / 58
Therefore, P(2 state or more | College Degree) will be;
⇒ P(2 states or more and college degree) / P( College Degree )
⇒ ( 18 / 58 ) / ( 20 / 58 )
⇒ ( ( 18 / 58 )58 ) / 20
⇒ (( 18 × 58 ) / 58 ) / 20
⇒ 18 / 20
⇒ 0.9
Therefore, The required probability is 0.9
Option d) 0.900 is the correct answer.
