A new library, L, is to be built at some point along a straight road, R, such that its distance from train station, T, is the sh

andreyandreev [35.5K]

Answer:

Coordinates of the new library is (150, 70)

Step-by-step explanation:

To get the shortest possible distance means that line from point T to point R has to be perpendicular.

Now, the equation of R is given as;

y = x - 80 - - - (1)

For T to be perpendicular, it means it will have a slope equal to the negative reciprocal of line R.

Thus, slope of T is -1/1 = - 1

Thus, using line - slope intercept of y = mx + c, we can find equation of T as;

140 = -1(80) + c

140 = -80 + c

c = 140 + 80

c = 220

Thus, equation is;

y = -x + 220 - - - (eq 2)

Adding equation 1 to equation 2,we have;

y + y = 220 - 80

2y = 140

y = 140/2

y = 70

Putting 70 for y in eq 1 gives;

70 = x - 80

x = 70 + 80

x = 150

Thus;

Coordinate of the new library is (150, 70)

Perform the indicated operation. f(n) = 4n - 5, g(n) = n^2 - 5 Find: (f - g) (n)

Alex777 [14]

Hi there!

$\large\boxed{-n^2 + 4n}$

Begin by evaluating f - g:

4n - 5 - (n² - 5)

Simplify:

4n - 5 - n² + 5 = 4n - n²

Or it can be written as -n² + 4n to match the first answer choice.

Last week Lisa had gross earning of $441.30. Cathy receives a base salary of $375 and a commision on sales exceeding her quota o

vova2212 [387]

Answer:

4.25%

Step-by-step explanation:

Step 1: Calculate the commission paid

Commission = Gross earning - base salary

Commission = 441.3 - 375

Commission = 66.3

Step 2: Calculate the commission sales

Commission sales = Total sales - quota sales

Commission sales = 6560 - 5000

Commission sales = 1560

Step 3: Calculate the rate of commission

x% of 1560 = 66.3

x% * 1560 = 66.3

x% = 0.0425

x = 4.25%

Therefore, the rate of commission was 4.25%.
