After finishing her management degree, jenny started a job with a fixed percentage for an annual raise. jenny’s annual salary is modeled by the equation a = 100,000(1.065)t where t represents the years she’s been working for the company. her friend donald graduated from the same college and started a different job. his annual salary is modeled by the equation a = 85,000(1.07)t. after five years, jenny has an annual salary of $, and the difference of donald’s and jenny’s salaries is $.

After five years, Jenny has an annual salary of $137,008.67

the difference of Donald’s and Jenny’s salaries is $17,791.77

Step-by-step explanation:

Jenny's annual salary =

Donald's annual salary =

We need to find out annual salary for Jenny after 5 years

Here 't' represents the number of years

So we plug in 5 for t  and find out A

Jenny's annual salary =

After five years, Jenny has an annual salary of $137,008.67

Now we find annual salary for Donald after 5 years

So we plug in 5 for t  and find out A

Donald annual salary =

To find the difference of Donald  and Jenny salary we subtract

Jenny's salary - Donald's salary after 5 years

137,008.67 - 119,216.90= 17791.77

the difference of Donald’s and Jenny’s salaries is $17,791.77

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
