and since it goes thru the origin, the y int is 0
so ur equation is : y = 2x <==
Answer:
The equation of line is y = 2x.
Step-by-step explanation:
Consider the provided information.
A coordinate grid is shown. The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line, and the y axis values are from negative 10 to positive 10 in increments of 2 for each grid line.
The slope intercept form of an equation of line is: y = mx + c
Where m is the slope and c is the y intercept.
[tex]Slope = m = \frac{Rise}{Run}[/tex]
Increments or decrements in x axis value represent the Run. Increments or decrements in y axis value represent the Rise.
It is given that "y axis values are from negative 10 to positive 10 in increments of 2 for each grid line."
Thus the Rise is 2 unit.
The x axis values are from negative 5 to positive 5 in increments of 1 for each grid line,
Thus the Run is 1 unit.
Hence the slope is: [tex] Slope=m=\frac{Rise}{Run}=2[/tex]
It is given that line passing through (0,0) it means the y intercept is 0.
Now substitute the value of m and y intercept in slope intercept form..
y = 2x + 0
y = 2x
Hence, the equation of line is y = 2x.

Jim spends 3 1/2 days a month away from home if he does this for 6 1/2 months how many days would Jim be away from home
Answers
Jim would be away from home for approximately 23 days.
Explanation:To find out how many days Jim would be away from home, we need to multiply the number of days he spends away from home in a month by the number of months he does this for:
3 1/2 days x 6 1/2 months = (7/2) x (13/2) = 91/4 = 22.75 days
Since we can't have a fraction of a day, we round up the decimal to the nearest whole number. So, Jim would be away from home for approximately 23 days.

y = mx + b (b) Your answer: b = y - mx b = x- ym b = y + mx b = mx-y
Answers
You would subtract b from both sides, giving you y-b=mx. You have to get b isolated, so you'd subtract y from both sides, giving you -b=mx-y. The b is positive, so you'd multiply -1 to both sides, giving you b=-mx+y. By rearranging the letters you get b=y-mx.

The number 'N' of cars produced at a certain factory in 1 day after 't' hours of operation is given by N(t)=100t-5t^2, 0< or equal t < or equal 10. If the cost 'C' (in dollars) of producing 'N' cars is C(N)=15,000+8000N, find the cost 'C' as a function of the time 't' of operation of the factory
Then Interpret C(t) when t=5 hours as a new function.
Answers
Answer:
We know that:
[tex]C_{(N)}=15000+8000N[/tex]
So first we need to substitute the next equation in the C(N) equation
[tex]N_{(t)} = 100t-5t^{2}[/tex]
And therefore we have:
[tex]C_{(t)}=15,000 + 8000*(100t-5t^{2})\\C_{(t)}=15,000 + 800000t-40000t^{2}[/tex]
Finally we replace at t = 5 in the equation above and we have:
[tex]C_{(5)}=15,000 + 800000*5-40000*5^{2}\\C_{(5)}= 3015000[/tex]
The interpretation is that after 5 hours of operation, we have wasted 3015000 dollars producing cars.
To calculate the cost of production as a function of time, substitute the production function N(t) into the cost formula C(N). After simplifying, the cost function is C(t) = 15,000 + 800,000t - 40,000t². At 5 hours, the cost is 3,015,000 dollars.
Explanation:To find the cost C as a function of the time t of operation of the factory, we first use the formula for the number of cars produced N(t) = 100t - 5t². Then we substitute the expression for N(t) into the cost function C(N) = 15,000 + 8000N.
Substituting N(t) into C(N), we get:
C(N(t)) = 15,000 + 8000(100t - 5t²)C(t) = 15,000 + 8000(100t) - 8000(5t²)C(t) = 15,000 + 800,000t - 40,000t²This is the cost C as a function of time t.
When t = 5 hours, the function becomes:
C(5) = 15,000 + 800,000(5) - 40,000(5²)C(5) = 15,000 + 4,000,000 - 1,000,000C(5) = 3,015,000 dollarsThis result means that the cost of production after 5 hours of operation is 3,015,000 dollars.

during the summer you work 30 hours per week at a gas station and earned $8.75 per hour. You also work as a landscaper for $11 per hour and your work as many hours as you want. You want to earn a total of $400 per week. How many hours mostly work as a landscaper?
Answers
To earn a total of $400 per week, considering you already earn $262.50 working 30 hours a week at a gas station, you need to make up the rest ($137.50) working as a landscaper. This equates to approximately 12.5 hours of work a week at an hourly rate of $11.
Explanation:The nature of the question is mathematical, specifically relating to linear equations. Initially, we know you're earning $8.75 per hour from your job at the gas station, working 30 hours a week, which gives you a total of $8.75 * 30 = $262.50 per week. Your goal is to earn $400 in total per week. Therefore, your earnings from the landscaping job need to make up the difference, which is $400 - $262.50 = $137.50.
Next, to find out how many hours you need to work as a landscaper, we divide that by the landscaper's hourly wage of $11, so $137.50 / $11 = 12.5 hours approximately. Hence to meet your target of $400 per week, you need to work about 12.5 hours as a landscaper, in addition to your 30 hours at the gas station each week.

how many 5 3/4 inch pieces of yarn can be cut from a roll that has 60 inches of yarn?
Answers
Find the number if 5/3% of it is 4.75
Answers
To find the number when 5/3% of it is 4.75, you can set up the equation (5/3%) x N = 4.75 and solve for N.
Explanation:To find the number when 5/3% of it is 4.75, we can set up the equation:
(5/3%) x N = 4.75
To solve for N, we need to convert the percentage to a decimal:
5/3% = 5/3 x 1/100 = 5/300 = 1/60
Now we can rewrite the equation:
(1/60) x N = 4.75
To isolate N, we can multiply both sides of the equation by 60:
N = 4.75 x 60 = 285
Therefore, the number is 285.

The grass in the outfield of a professional baseball stadium is trimmed to a height of 5.08 * 10^-5 miles. Which unit of measurement is most appropriate to measure in height?
Answers
The height is given as 5.05 x 10⁻⁵ miles.
Because this is in English units, we should reduce the height to inches.
Note that
1 mile = 5280 ft
= 5280*12 = 63360 in
Therefore the height is
(5.08 x 10⁻⁵ miles)*(63360 in/mile) = 3.219 in
Answer:
3.2 in (nearest tenth)
The given measurement is in English units, so the conversion stays in English units.
A falling stone is at a certain instant 250 feet above the ground and 3 seconds later it is only 10 feet above the ground. From what height was it dropped?
Answers
Assume that g = 32 ft/s² and ignore air resistance.
At time t seconds, the stone is 250 ft above ground. Therefore
(1/2)gt² = h - 250 (1)
After another 3 seconds, the stone is 10 ft above ground. Therefore
(1/2)g(t+3)² = h - 10 (2)
Subtract (1) from (2).
(1/2)g[(t+3)² - t²] = 240
32(t+3)² = 480
(t+3)² = 15
t = 0.873 s
From (1), obtain
16*(0.873)² = h - 250
12.194 = h - 250
h = 262.194 ft
Answer: 262.2 ft (nearest tenth)
Final answer:
By applying the equations of motion for an object in free fall, it's determined that the stone was dropped from 404 feet above the ground, considering its positions at two separate times and using the acceleration due to gravity.
Explanation:
To find the original height from which the stone was dropped, we can use the equations of motion under constant acceleration due to gravity. Since we are dealing with a vertical motion and we are given the stone's positions at two different times, the most appropriate equation to use is:
h = h0 + v0t - ½gt²
Where:
h is the final height of the object above the ground,h0 is the initial height of the object above the ground,v0 is the initial velocity (which is 0 for a dropped object),g is the acceleration due to gravity (approximately 9.8 m/s², but since we are using feet, we use 32 ft/s²), andt is the time in seconds.We know that the stone is 250 feet above the ground at a certain instant and 10 feet above the ground 3 seconds later. Thus, we can use these values to solve for h0 in two steps. Firstly, convert the given heights to the same unit of measurement if necessary (in this case, they are already in feet). Then, substitute the given values into the equation:
At t = 3 seconds, h = 10 feet:
10 = h0 - ½(32)(3)²
Solving this equation gives us:
h0 = 10 + ½(32)(3)² = 10 + 144 = 154 feet
However, this calculation only accounts for the latter part of the fall. To find the total height from which it was dropped, we need to consider the height above the 250 feet mark.
Since we initially observed the stone at 250 feet and then at 10 feet above the ground, it implies the stone was dropped from 250 feet + 154 feet = 404 feet above the ground.
