Find the coefficient of the t4
term in the expansion of
(4t– 3)^5

-4320t^2

Step-by-step explanation:

Use Pascal's triangle to figure out the variables.

In the 5th expansion, we see that the 4th term is:

10x^2 y^3

Plug in the values,

10*(4)^2 * (-3)^3 = -4230.

However, since the -3 in the original expression does not have a variable next to it, we do not include it in our answer.

Therefore, the 4th term is -4230t^2

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

0 is its x and y coordinate
