Answer:
y= - 4/6x+1.66
Step-by-step explanation:
To get the slope you subtract y2-y1 / x2-x1. This gives the slope. Then you need to get the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Write the equation of the parabola in vertex form.
vertex (4.1), point (3,-4)
Answer:
[tex]\boxed{\bold{y=-5(x-4)^2+1}}[/tex]
Step-by-step explanation:
[tex]y=a(x-h)^2+k[/tex] - vertex form of equation of a parabola where vertex is (h,k)
[tex]y=a(x-4)^2+1[/tex] - vertex form of equation of a parabola where vertex is (4,1)
The parabola goes through point (3, -4) so if x=3 then y=-4
[tex]-4=a(3-4)^2+1\\\\-4-1=a(-1)^2+1-1\\\\-5=a\cdot1\\\\{}\ \ a=-5[/tex]
Therefore the equation of the parabola in vertex form with vertex (4,1), going through point (3,-4):
[tex]y=-5(x-4)^2+1[/tex]

On a windmill, the tip of one blade moves in a circular motion. The maximum height is 18 feet and the minimum height is 4 feet. The height of the tip of the blade (in feet) can be modeled by the function h(x)=−14sinx+18 h(x)=−14sinx+18 where x is time in seconds. Use the inverse function to determine how many seconds it will take to make a full rotation for one blade.
A 0.3 second
B 0.6 second
C 1.6 seconds
D 3.2 seconds
Answer:
The correction is D
Step-by-step explanation:
From the question we are told that
The maximum height is [tex]h_m = 18 ft[/tex]
The minimum height is [tex]h_i = 4 ft[/tex]
The function that models the height of the blade is [tex]h(x) =- 14 sin(x) + 18[/tex] here x is time in seconds
Now at maximum height
[tex]18 = - 14 sin(x) + 18[/tex]
=> [tex]-14 sin(x) =0[/tex]
=> [tex]sin(x) =0[/tex]
=> [tex]x =sin^{-1}[0][/tex]
=> [tex]x =0 \ s[/tex]
Now at minimum height
[tex]4 = -14 sin(x) + 18[/tex]
=> [tex]-14 = -14 sin(x)[/tex]
=> [tex]sin (x) = 1[/tex]
=> [tex](x) = sin^{-1}[1][/tex]
=> [tex]x = 1.6 \ s[/tex]
Now this values is the time taken to move from the higher position of the blade to the lower position of the blade
Now it will take this same amount of time to complete the circle
So the total time take is
[tex]x_t = 2 * |x|[/tex]
=> [tex]x_t = 2 * 1.6[/tex]
=> [tex]x_t = 3.2 \ s[/tex]

An airplane flies from Minneapolis to Chicago in 58 minutes.
If it is 572,000 meters from Minneapolis to Chicago, what is the plane's average speed?
20 points and Brainliest.
Answer:
9862.069 meters per minute
or
591724.138 meters per hour
Step-by-step explanation:
572000 meters ÷ 58 minutes = 9862.069 meters per minute
If you need this in meters per hour, multiply by 60 as there are 60 minutes in 1 hour.
60 * 9862.069 = 591724.138 meters per hour
If you need to convert to miles per hour:
1 meter = 0.0006213712 miles
591724.138 * 0.0006213712 = 367.68 miles per hour
Patricia jumped 5 times in 12 minutes. At that rate, how many times
would she jump in 8 hours?
Tahol nntinnal
Answer:
200
Step-by-step explanation:
Change 8 hours to minutes so the units are the same. 8(60) = 480. Using a proportion the equation is 5/12 = j/480. [jumps/minutes] To solve the equation, cross multiply: 12j = 5(480) ; 12j = 2400; j = 2400/12; j = 200.

9 4/5 KPH is about 6.1224489795918 Kilometers per minute
Multiply by 2 1/5 KPM
6.1224489795918 x 2 1/5 = 13.4693877551 Minutes
Answer: 13.469 or about 13.5 minutes
Step-by-step explanation:
Estimating part:
The first number can be rounded to 10, and second number to 2
You can set up a proportional equation
[tex]\frac{10 kilometers}{60 minutes} = \frac{2 kilometers}{x}[/tex]
then cross multiply to get 10x=120, then divide to get x = 12 minutes
Exact answer:
I like making fractions into decimals to make it easier to see
The first number as a decimal is 9.8, and the second is 2.2
Set up another proportional equation
[tex]\frac{9.8 kilometers}{60 minutes} = \frac{2.2 kilometers}{x}[/tex]
cross multiply to get 9.8x = 132
divide by 9.8 on both sides to get x = 13.5 minutes

(Terms and Equations in Factual Problems) The Smith family consists of four people. Anna is three years older than Matthias. Miss Smith is four times as old as Anna. Mr Smith is five years older than his wife. Together they are 72 years. How old are the family members?
Given:
Anna is three years older than Matthias.
Miss Smith is four times as old as Anna.
Mr Smith is five years older than his wife.
Together they are 72 years.
To find:
The age of each family member.
Solution:
Let age of Matthias be x years.
Anna is three years older than Matthias.
Anna's age = x+3
Miss Smith is four times as old as Anna.
Miss Smith's age = 4(x+3)
Mr Smith is five years older than his wife Mrs Smith.
Mr Smith's age = 4(x+3)+5
Together they are 72 years.
[tex]x+(x+3)+4(x+3)+[4(x+3)+5]=72[/tex]
[tex]x+x+3+4x+12+4x+12+5=72[/tex]
[tex]10x+32=72[/tex]
Subtract 32 from both sides.
[tex]10x=72-32[/tex]
[tex]10x=40[/tex]
Divide both sides by 10.
[tex]x=4[/tex]
Now,
Matthias's age = 4 years
Anna's age = 4+3
= 7 years
Miss Smith's age = 4(4+3)
= 4(7)
= 28 years
Mr. Smith's age = 4(4+3)+ 5
= 28+5
= 33 years
Therefore, the ages of Matthias, Anna, Miss Smith and Mr Smith are 4, 7, 28 and 33 respectively.

The total amount of weight on an elevator cannot exceed 1,800 pounds. a delivery person is on the elevator delivering packages. together, the delivery person and the packages weigh 520 pounds. if the average weight of a person is 160 pounds, set up and solve an inequality to determine how many additional people, p, the elevator can hold.
Answer:
p ≤ 8
Step-by-step explanation:
Given the following :
Maximum weight elevator can hold ≤ 1800
Weight of delivery person and packages = 520 pounds
Average weight of a person = 160 pounds
Inequality to show how many additional people elevator can hold?
(weight of delivery person and packages + average weight of persons * number of persons) ≤ 1800
Let p = number of persons
(520 + 160p) ≤ 1800
160p ≤ 1800 - 520
160p ≤ 1280
p ≤ 1280 / 160
p ≤ 8

Key: 24 is a student who grabbed
24 snacks.
Answer:B
Step-by-step explanation:
The distribution of the number of snacks grabbed is skewed right with a centre around 18 and varies from 12 to 45. There are possible outliers at 38, 42, and 45. Therefore, option B is the correct answer.
What is the stem plot?A stem and leaf plot also called a stem and leaf diagram is a way of organizing data into a form that makes it easy to observe the frequency of different types of values. It is a graph that shows numerical data arranged in order. Each data value is broken into a stem and a leaf.
A stem and leaf plot is represented in form of a special table where each first digit or digit of data value is split into a stem and the last digit of data in a leaf. This " | " symbol is used to show stem values and leaf values and it is called as stem and leaf plot key.
First, we can see if the graph is symmetric. A symmetric graph is even on both sides of the centre. As there are a lot more students that grabbed a small number of snacks, the data is not even around the centre (which is somewhere around 20 or 30 snacks). This means that the graph is not symmetric, making the second answer incorrect.
Next, we can check if the graph is skewed right or left. If the left of the graph represents a smaller amount of snacks and the right of it represents a higher number of snacks, we can see that most of the data is on the left of the graph. There are a few values to the right, but the overwhelming amount of data is on the left, making the distribution skewed to the right. This keeps the first and last answers possible,
Moreover, we can find the centre of the distribution. This is generally equal to the median, which is 18, so the centre is around 18.
After that, we can see what values vary. The lowest tens value is 1, and the lowest value in that is 2, making the lowest value 12. Similarly, the highest tens value is 4, and the highest value there is 5, making the range 12 to 45. This leaves the last answer, but we can check the outliers to make sure.
With the data, we can calculate the first quartile to be 15, the third quartile to be 21.5, and the interquartile range to be 21.5-15 = 6.75. If a number is less than Q₁ - 1.5 × IQR or greater than Q₃ + 1.5 × IQR, it is a potential outlier. Applying that here, the lower bound for non-outliers is 15 - 6.5 × 1.5 = 5.25, and the upper bound if 21 + 6.5 × 1.5 = 30.75. No values are less than 5.25, but there are four values greater than 30.75 in 32, 38, 42, and 45. There are possible outliers at 38, 42, and 45, matching up with the last answer.
Therefore, option B is the correct answer.

From your house, Joe's mechanic shop is 25 miles away. At what rate must you travel to
go 25 miles to make your appointment in 0.27 hours?
Answer:
rate = 92.6 miles/hours
Step-by-step explanation:
Here rate means speed
formula for speed = distance/time
since distance here is 25 miles
and time taken is 0.27 hours
thus,
speed = distance to be traveled/time in which this distance is covered
speed = 25 miles/ 0.27 hours = 92.6 miles/hours
thus, rate should be 92.6 miles/hours to make the appointment in time.
