y=mx+b (-6,-5) and (-4,-4)
Step-by-step explanation:
We will put this in y=mx +b form so first calculate the slope
m= (-4)-(-5)/(-4)-(-6)
m= 1/2. So y= x/2. +b
Now just substitute the x and y values of either given point to calculate b
I will use (-4,-4)
-4= (1/2)(-4) +b
-4= -2 +b
b=-2
So equation is y= x/2 -2

I search it.
Answer:
Step-by-step explanation:
Equation of line in slope- y intercept form:
First find the slope.
[tex]\boxed{Slope= \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf = \dfrac{-4-[-5]}{-4-[-6]}\\\\=\dfrac{-4+5}{-4+6}\\\\=\dfrac{1}{2}[/tex]
Equation:
[tex]y =\dfrac{1}{2}x+b[/tex]
Choose any point and substitute the x and y value in the above equation.
(-6,-5)
[tex]\sf -5=\dfrac{1}{2}*(-6) + b\\\\-5 = -3+b\\\\-5+3=b\\\\-2 = b[/tex]
Equation:
[tex]y = \dfrac{1}{2}x - 2[/tex]
A water sample shows 0.073 grams of some trace element for every cubic centimeter
of water. Anthony uses a container in the shape of a right cylinder with a diameter of
11.4 cm and a height of 16.5 cm to collect a second sample, filling the container all the
way. Assuming the sample contains the same proportion of the trace element,
approximately how much trace element has Anthony collected? Round your answer
to the nearest tenth.
The amount of trace element has Anthony collected, assuming the sample contains the same proportion of the trace element, is 114.6 grams.
What is of volume of cylinder?Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
The volume of cylinder can be given as,
[tex]V=\dfrac{\pi r^2h}{4}[/tex]
Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.
A water sample shows 0.073 grams of some trace element for every cubic centimeter of water. The proportion of element with water is,
[tex]p=\dfrac{0.073}{1}[/tex]
Anthony uses a container in the shape of a right cylinder with a diameter of 11.4 cm and a height of 16.5 cm to collect a second sample, filling the container all the way.
The total volume of the container is,
[tex]V=\dfrac{\pi (11.4)^2\times16.5}{4}\\V\approx1684 \rm\; cm^3[/tex]
The sample contains the same proportion of the trace element. Let the trace element has Anthony collected is x. Thus,
[tex]\dfrac{x}{1684-x}=\dfrac{0.073}{1}\\x=122.932-0.073x\\x+0.073x=122.932\\x=\dfrac{122.932}{1.073}\\x\approx114.6\rm\; gram[/tex]
Thus, the amount of trace element has Anthony collected, assuming the sample contains the same proportion of the trace element, is 114.6 grams.

What is the area of the shaded region below?
Answer:
Step-by-step explanation:
Remark
The triangle with the shaded region makes exactly 1/4 of the entire circle. So the plan is to find the area of the circle and divide by 4. That gives you the area of the triangle and the shaded region. Then you find the area of the triangle and subtract it from what you just found.
Area of the circle
Area of the circle = pi * r^2
r = 12 cm
pi = 3.14
Area of the circle = 3.14 * 12^2
Area of the circle = 3.14 * 144
Area of the circle = 452.16 cm^2
Area of 1/4 of the circle
Area of 1/4 of the circle = (1/4)*452.16
Area of 1/4 of the circle = 113.04
Area of the triangle
b = r
h = r
b = 12 cm
h = 12 cm
Area = 1/2 b * h
area = 1/2 * 12 * 12
area = 72
Area of the shaded part
Shaded part = area of 1/4 of the circle - area of triangle
Area shaded part = 113.04 - 72 = 41.04
Answer area of shaded part = 41.04
Jason is considering two different jobs that he has been offered and he likes the atmosphere and
other employees equally at both companies.
With the first job he would be an apartment property manager for AMLI Company. This job is
offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he
sets a one year lease up with. The company expects Jason to work all 52 weeks of the year and 40
hours per week. He was told he could expect to set up an average of 5 lease agreements for each
week that he works.
With the second job he would work as water treatment facility manager in Gwinnett County. He
would be paid an annual salary of $46,000 a year, there are no bonuses by he gets a week off.
Both companies deduct for Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and
Federal Income Tax (14%).
AMLI's individual health insurance costs $115 per month. Gwinnett County's health insurance is
only $25 per month for an individual.
Part A: Determine how much Jason will receive in one year after all deductions have been taken
for each company. Show your work neatly.
The amount of money that Jason will receive in one year after all deductions have been taken for each company is $30,780.5 and $32562.
What is the final amount?With the first job, he would be an apartment property manager for AMLI Company.
This job is offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he sets a one-year lease-up with.
The company expects Jason to work all 52 weeks of the year and 40 hours per week.
He was told he could expect to set up an average of 5 lease agreements for each week that he works.
The amount after one year will be given by an equation
Let y be the amount, x be the number of hours in a week and z be the number of the week.
y = 19x + 40z
The total number of hours in a year will be
x = 2080
Then
y = 19 × 2080 + 40 × 52
y = $ 41,600
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 41,600 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 32,160.5
The amount after the insurance will be
Amount = 32160.5 - 115 × 12
Amount = $ 30780.5
With the second job, he would work as a water treatment facility manager in Gwinnett County. He would be paid an annual salary of $46,000 a year, there are no bonuses and he gets a week off.
The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be
→ 46,000 × 0.938 × 0.988 × 0.97 × 0.86
→ $ 35,562
The amount after the insurance will be
Let the number of the worker be 10. Then
Amount = 35,562 - 10 × 12 × 25
Amount = 35562 - 3000
Amount = $32562

are the total costs at the
OI two truck rental
two companies equal?
Company A:
Company B:
$20 per day plus $.70 per mile
$45 per day plus S .25 per mile
Set up the equation and solve for miles:
20 + 0.70m = 45 + 0.25m
Subtract 20 from both sides
0.70m = 25 + 0.25m
Subtract 0.25m from both sides
0.45m = 25
Divide both sides by 0.45
M = 55.56 miles
answer: 55.56 miles ( rounded to nearest hundredth’s)

Write f(x)=|x-2| as a piecewise function.
Answer:
Hi! A piecewise function is a function defined by multiple sub-functions, or pieces of different functions over different intervals. Piecewise definition is a way of expressing the function and is not actually integral to the function itself.
f(x) = |x - 2| is an absolute value function. As a piecewise function, it's written like this:
f(x) = {x - 2, x ≥ 2
{-x + 2, x < 2
