Edgar ran eee meters per second, and mathieu ran mmm meters per second. the boys ran for ttt seconds.
the expression t(m-e)t(m−e)t, left parenthesis, m, minus, e, right parenthesis describes how many more meters mathieu ran than edgar ran during that time. we can also use the expression tm-tetm−tet, m, minus, t, e to represent the same quantity.
match each amount in the situation with the expression that represents it.\

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

hi how are you doing today, if you need just ask me.

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
