Answer:

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Step-by-step explanation:

The amount is given by

$V = Pe^{rt}$

Given P = $6520

r = 2.5%

t = 3 years

Substituting the given values, we get -

$V = 6520 * e^{2.5*3/100 }\\V = 6520 * 1.078\\V = 7028.56$

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Geometry, please answer question ASAP

Aleks [24]

Magnitude of angle D = 170
Because,
Sum of interior angles of a pentagon = 540 degree
That is,
Angle A + angle B + angle C + angle D + angle E = 540 degree
87degree + 125 degree + 63 degree + 95 degree + angle D = 540 degree

So that gives angle D = 170 degree

Hope this helps.
