The geometric sequence a_1[/tex] is defined by the formula = - ⅓ = *(-3) Find the sum of the first 75 terms in the sequence.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: need picture of problem

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

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