Answer:

Step-by-step explanation:
sub 45 into x
h(x) = h(45)
h(45) = 1/9(90-45)
= 1/9(45)

(-9, -2) and (-3,6)
Answer:
[tex]d = 10[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-3-(-9))^2+(6-(-2))^2}[/tex]
[tex]d = \sqrt{(-3+9)^2+(6+2)^2}[/tex]
[tex]d = \sqrt{(6)^2+(8)^2}[/tex]

What is the slope of the line that passes through the points (0, 7)(0,7) and (8, 7) ?(8,7)? Write your answer in simplest form.
Answer:
0
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the 2 points:
(y2 - y1) / (x2 - x1)
(7 - 7) / (8 - 0)
0/8
= 0
So, the slope is 0.
The slope is 0.
what is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
(0,7) and (8, 7)
slope = (y2 - y1)/ (x2 -x1)
slope = (7-7) / (8-0)
slope = 0/7
slope= 0
Hence, the slope is 0.

1) Alexa Corp acquired several assets from Bonsai Corp. for $4,200,000. Assets acquired included a building, a stamping machine, and a forklift. An appraisal of the assets valued the building at $2,400,000, the press at $1,000,000, and the conveyor belt at $600,000. What is the value that will be assigned to each of these assets?
Answer:
Value assigned for Building = $2,520,000
Value assigned for Press = $1,050,000
Value assigned for Conveyor belt = $630,000
Step-by-step explanation:
Total appraisal value = Building + Press + Conveyor belt
Total appraisal value = 2,400,000 + 1,000,000 + 600,000
Total appraisal value = $4,000,000
Value assigned for Building = (2,400,000/4,000,000)*4,200,000
Value assigned for Building = $2,520,000
Value assigned for Press = (1,000,000/4,000,000)*4,200,000
Value assigned for Press = $1,050,000
Value assigned for Conveyor belt = (600,000/4,000,000)*4,200,000
Value assigned for Conveyor belt = $630,000

If a loading ramp is placed next to a truck, at a height of 3 feet, and the ramp is 17 feet long, what angle does the ramp make with the ground
Answer:
10.16°
Step-by-step explanation:
To solve for this question, we use Sine rule
Sin θ = Opposite/Hypotenuse
θ =??
Opposite = Height of the truck = 3 feet
Hypotenuse = length of the ramp = 17 feet
Hence
Sin θ = 3/17
Sin θ = 0.1764705882
θ = arcsin(0.1764705882)
θ = 10.16424862°
Approximately
10.16°
The angle the ramp makes with the ground is 10.16°
The angle that the ramp makes with the ground is 10.2 degrees
The set-up will give a right triangle.
Given the following parameters:
Length of the ramp = 17feet (hypotenuse)Height of the truck = 3feet (opposite)To get the angle of elevation, we will use the SOH CAH TOA identity as shown:
Sin theta = opp/hyp
Sin theta = 3/17
theta = arcsin(3/17)
theta = 10.2 degrees
Hence the angle that the ramp makes with the ground is 10.2 degrees

What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
We take two points lying on the line representing the best relationship between variables X and Y.
Points are (1, 9) and (2, 8), so the slope will be (y₂ - y₁)/(x₂ -x₁)
Slope = (9- 8)/(1-2) = -1
Since the slope is negative, the Slope of (-1) shows the negative relationship between X and Y which may be represented by Y = (- X), the equation of a line.
thus It is a negative Association for sure.
A perfect negative correlation has a value of -1.0 and indicates that when X increases by z units, Y decreases by exactly z; and vice-versa. In general, -1.0 to -0.70 suggests a strong negative correlation, -0.50 a moderate negative relationship, and -0.30 a weak correlation.
Therefore, the association between variables X and Y can be best described as Option c.) moderate negative association

You need a 40% alcohol solution. On hand, you have a 350 mL of a 15% alcohol mixture. You also have 90%
alcohol mixture. How much of the 90% mixture will you need to add to obtain the desired solution?
You will need
mL of the 90% solution
Submit Question
Let x be the amount of 90% solution you will use.
You have 350 mL of a 15% alcohol solution, so it contains 0.15 • 350 mL = 52.5 mL.
For each mL of the 90% solution that you use, you would add 0.9 mL of alcohol. So in the new mixture, the volume would be (350 + x) mL, and its concentration needs to be 40% so that
((52.5 + 0.9x) mL) / ((350 + x) mL) = 0.4
Solve for x :
(52.5 + 0.9x) / (350 + x) = 0.4
(52.5 + 0.9x) / 0.4 = 350 + x
131.25 + 2.25x = 350 + x
1.25x = 218.75
x = 175
so you will need to use 175 mL of the 90% solution.

Mike drew p pictures. Rick drew 41 fewer pictures than Mike. Choose the expression that shows how many pictures Rick drew.
(A.) p
(B.) 41 + p
(C.) p - 41
(D.) 41 - p
Answer:
It's p - 41.
Step-by-step explanation:
We're trying to find how many pictures Rick drew, which is 41 less than how many Mike drew, p. To find the expression in situations like these, always take how many fewer was drawn from the amount the other person drew, which would be 41 - p. But this would most likely give us a negative answer, which isn't possible. Switch them around and you have p - 41.

What is the distributive property 3(50.15)
Using the distributive property, 3(50.15) can be simplified to 150.45 by multiplying 3 with each term inside the parentheses.
The distributive property is a fundamental concept in mathematics, explains how multiplication distributes over addition or subtraction. It says that you can distribute or apply the multiplication to each term inside the parentheses separately when you multiply a number by a sum or difference enclosed in parentheses.
expression: 3(50.15)
apply the distributive property, which states that a number outside parentheses can be multiplied by each term inside the parentheses.
Multiply 3 by 50.15.

calculate the rate of change in your neighborhood population of squirrels based on the data from a june 2015
The question is incomplete. Here is the complete question.
Scenario: You are bored during quarantine. However, you have been observing a bird feeder in your backyard and wow... do there seem to be a lot of squirrels in your neighbourhood. You begin to wonder how many squirrels are actually in your neighbourhood and devise an experiment to track their population.
Part 1. Using the data below, estimate the population of squirrels in your neighbourhood as if you employed the Mark-and-Recapture method. Please be sure to include any units in your final answer.
#captured on 06/01/20 10
#captured on 06/30/20 6
#recaptured on 06/30 from 06/01 3
Part 2. Calculate the rate of change in your neighbourhood population of squirrels based on the data from a June 2015 report that indicated a population of 40 squirrels.
Part 3. Calculate the intrinsic growth rate (r) for this population of squirrels based on the data you have acquired so far.
Part 4. Interpretations: In 1-2 sentences, summarize what's happening here (e.g. is the population growing or shrinking or staying the same?) and propose one plausible explanation for this change.
Answer: Part 1: Population of 20 squirrels
Part 2: Rate of change 50%
Part 3: r = -0.1386 anos
Step-by-step explanation: The Mark-and-Recapture method is a method to estimate a population when counting each individual is impractical. The method consists in capture a small population of individuals, mark them and released them back to the population. After a while, you catch another group and record the ones with the mark.
The calculations are made following this formula:
[tex]N=\frac{M*C}{R}[/tex]
N is the estimated population
M is marked individuals
C is total number of captured individuals (with and without the mark) the second time
R is recaptured individuals with the mark.
Part 1: Population of squirrels will be:
[tex]N=\frac{10*6}{3}[/tex]
N = 20
Population of squirrels in 2020 is 20 squirrels.
Part 2: Rate of change is calculated by the change in the population divided by the original population:
rate = [tex]\frac{20-40}{40}[/tex]
rate = - 0.5 or 50%
Part 3: The model for a population growth is exponential:
[tex]N=N_{0}e^{rt}[/tex]
N is population at that moment
N₀ is initial population
r is growth rate
t is period of time
Growth rate will be:
[tex]N=N_{0}e^{rt}[/tex]
[tex]20=40e^{5r}[/tex]
[tex]e^{5r}=0.5[/tex]
[tex]5r=ln(0.5)[/tex]
[tex]r=\frac{ln0.5}{5}[/tex]
[tex]r=-0.1386[/tex]
Growth rate (r) for the population of squirrels after 5 years is [tex]r=-0.1386[/tex] years.
Part 4: The growth rate has a negative sign, which means population is decreasing along the 5 years, so population is shrinking.
One possible explanation is the environment the population are in is lacking the squirrels primary need, i.e., squirrels' food source is diminishing, causing the population to decrease.
