On mike's 1st birthday, a savings account is opened for him containing $10,000. on his 5th birthday the account has grown to $13,500 and $1,000 is added. on his 13th birthday, the account has grown to $17,000 and $2,000 is added. on his 16th birthday, he withdraws $5,000 to buy a car, leaving balance of $15,000. on his 18th birthday, his account contains $16,500, which he will use for college. no other deposits or withdrawals are made. calculate the time-weight ed rate of return over the 17-year period. (a) less than 0.05 (b) at least 0.05, but less than 0.30 (c) at least 0.30, but less than 0.55 (d) at least 0.55, but less than 0.80 (e) at least 0.80

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

it is only things thain can be deafeated

step-by-step explanation:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
