P=principal=$6000
t=time period=6 years

Option A
n=4 (compounded 4 times a year, or quarterly)
r=0.075
Future Amount
=P(1+r/n)^(nt)
=6000(1+0.075/4)^(4*6)
=$9370.746

Option B:
e=2.7182818284 (Napier's constant)
r=interest rate = 0.072
Final amount
= Pe^(rt)
=6000*e^(0.072*6)
=9242.011

Therefore option A is more profitable.

If the measures of the angles of a triangle are in the ratio of 19:13:4, then the expressions 19x, 13x, and 4xrepresent the meas
White raven [17]
Well this isn't college math lol

You do 19x + 13x + 4x = 26x

180 divided by 26x =        x = 6.92307...

plug in x then  round to tenth

6.9 x 19 = 131.1 degrees

6.9 x 13 = 89.7 degrees

6.9 x 4 = 27.6 degrees

I'm not too sure on this can i have some help

Welcome to Brainly. We are here to help! 

Similar polygons vary directly with each other. They have the same scale.

Something I notice about the polygons is that both of the sides are decreased by 10.

40-30= 10 and 28-18=10

Try to find the scale.

40/28= 1.42857....

30/18= 1.666666777


I would say these are not similar polygons. They do not share the same scale.

I hope this helps!
