Your $840 annual bonus increases by 5% each year. you deposit $3000 in an account that earns 2.5% annual interest compounded yearly. write and graph a function that represents this situation. plz its a test

solution: - as given the annual bonus =$840 increases at a rate of 5% be each year .

⇒ r= 5% =0.05

so, the amount function after x years for this situation will be  

=$840 increases at a rate of 2.5% each year .

⇒ r= 2.5% =0.025

so, the compound amount function after x years for this situation will be  

now to plot the graph we have to find points

at x =400,

by taking log on both sides and after solving it we get, y=0

and so

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
