a line passes through the points (14,5) and (19,15) determine and equation for a perpendicular line that passes through the poin

PSYCHO15rus [73]

The equation of the line thru <span> (14,5) and (19,15) is found as follows:

15-5 5
slope = m = ----------- = ------ = -1
19-14 5

Thus, the slope of any line perpendicular to this first line has the slope

m = -1/1 = -1.

Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>

Ash company report sales of $430,000 for year 1, $480,000 for year 2 and $530000 for year 3. Using year 1 as the base year, what

TiliK225 [7]

Answer:

12% increase

Step-by-step explanation:

Each year the sales increase by $50,000.

430,000 + 50,000 = 480,000

480,000 + 50,000 = 530,000

To find the percent change, write a proportion using 2 of the years.

$\frac{480,000}{430,000}=\frac{x}{100}$

To solve for x, cross multiply the numerator with the denominator of each fraction.

480,000(100) = 430,000(x)

48,000,000 = 430,000x

111.62 = x

Rounded this is 112% or 12% above 100%.

A square garden has sides that are 17 meters long. Fencing costs $9.00 per meter. How much would it

Papessa [141]

Answer:

$612

Step-by-step explanation:

Each side of the square garden is 17 meters, and fencing costs $9 per meter. "Around" is the key word, as it indicates perimeter. So, we just need to account for each side of the garden, and not the entirety of the garden. So,

17 · 9 = 153

This means that to cover one side of the garden, it would cost $153. Now, we just need to account for all sides of the garden.

153 x 4 = 612
