The point nearest to the origin on a line is at (4, -4). Find the standard form of the equation of the line.
Scrat [10]

Just did a specific one of these; let's do the general case.


The point nearest the origin is (a,b).


The line from the origin through the point is


bx - ay = 0


The line we seek is perpendicular to this one. We swap the coefficients on x and y, negating one, to get the perpendicular family of lines. We set the constant by plugging in the point (a,b):


ax + by = a^2 + b^2


ax + by -( a^2 + b^2) = 0


That's standard form; let's plug in the numbers:


4 x - 4 y - 32 = 0


x - y - 8 = 0

A spinner has three unusual sections: red, yellow, and blue.. The table shows the results of Nolan’s spins. Find the probability
Anika [276]

Answers:

  • Red = 1/3
  • Yellow = 7/15
  • Blue = 1/5

====================================================

Explanation:

Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.

  • Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3
  • Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15
  • Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5

A car salesman had $65,100 in total monthly sales last month. He made $1,953 in commission from those sales.
vitfil [10]

Answer:

Find out the what is the salesman's commission as a percent of his total monthly sales .

To prove

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

A car salesman had $65,100 in total monthly sales last month. He made $1,953 in commission from those sales.

Here

Part value = $1953

Total value = $ 65100

Put in the formula

Percentage = \frac{1953\times 100}{65100}

Percentage = \frac{195300}{65100}

Percentage = 3%

Therefore the salesman's commission as a percent of his total monthly sales is 3% .
