Answer:

YES

Step-by-step explanation:

use pythagorean theorem

15^2 + 36^2 = 39^2

225 + 1296 = 1521

1521=1521

Answer:

Yes

Step-by-step explanation:

$As\ we\ know\ that,\\The\ sides\ of\ a\ right\ triangle\ are\ pythagorean\ triplets\ in\ the\ form:\\a^2+b^2=c^2\\Here,\\39\ is\ the\ hypotenuse\ as\ it\ is\ the\ longest\ side.\\Hence,\\a^2+b^2=c^2\\Substituting\ a=15,b=36\ on\ the\ LHS,\\15^2+36^2\\=225+1296\\=1521\\On\ the\ RHS\ ,lets\ substitute\ c=39.\\Hence,\\c^2=39^2\\c^2=1521\\As\ LHS=RHS,\ The\ given\ triangle\ is\ a\ right\ triangle.$

A marketing company had a profit of 5625.14 in January a loss of 4250.35. In February and a profit of 1475.55 in March did the c

timofeeve [1]

Jan. profit..... 5625.14
feb..loss... - 4250.35
march..profit...1475.55

add the profits and subtract the losses...if the result is positive, then the company made a profit....if the result is negative, then the company had a loss.

(5625.14 + 1475.55) - 4250.35 = 7100.69 - 4250.35 = 2850.34.....as u can see, the result ended in a positive number....so, in the 3 month period, the company made a profit of $ 2850.34 <==

Y= 4/5 x-7 what are the y and x intercepts?

solmaris [256]

The x intercept is (8.75, 0) and y - intercept is (0, -7)

Solution:

Given that we have to find the x and y intercepts

Given equation is:

$y = \frac{4}{5}x - 7$

The x intercept is the point where the line crosses the x axis

The y intercept is the point where the line crosses the y axis

Finding x - intercept:

To find the x-intercept of a given equation, plug in 0 for 'y' and solve for 'x'

Substitute y = 0 in given equation

$0 = \frac{4}{5}x - 7\\\\\frac{4x}{5} = 7\\\\4x = 35\\\\x = \frac{35}{4} = 8.75$

Thus x intercept is (8.75, 0)

Finding y - intercept:

To find the y-intercept, plug 0 in for 'x' and solve for 'y'

Substitute x = 0 in given equation

$y = \frac{4}{5} \times 0 - 7\\\\y = 0 - 7\\\\y = -7$

Thus y - intercept is (0, -7)
