Find the coefficient of t to the 4th power in the expansion of (-9t-9) to the 7th power select one: a. -25,515

b. -100,442,349

c. -167,403, 915

d. -4,782, 969

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

is there a graph

step-by-step explanation:

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
