Answer:

x = 20

Step-by-step explanation:

sum of interior angles of 5 sided polygon: 180 x (5-2) = 540

7x + (4x + 5) + (5x - 5) + (6x + 10) + (4x + 10) = 540

26x + 20 = 540

26x = 520

x = 20

Alisiya [41]

Answer:

1) Her final bill: 334,5+ the tax

Her final bill = 334,5+ 26,76= 361,26 $

2) The gift card only has 350$ and the bill is 361,26

therefore she doesn't have enough money to pay for the sound bar

Which of the following represents dy/dx when y = e-2x sec (3x)?
Sindrei [870]
Using the product rule, which states that (uv)' = u'v + uv':
If y = (e^-2x)(sec3x)
y' = (e^-2x)'(sec3x) + (e^-2x)(sec3x)'
y' = -2(e^-2x)(sec3x) + (e^-2x)(3 sec3x tan3x)
y' = 3(e^-2x)(sec3x tan3x) -2e^-2x (sec3x)

This matches choice B.
