BARSIC [14]

Answer:

Purse A will contain 2400 (by magic) and Purse B will have 64 pennies

Step-by-step explanation:

how this happened is, by magic Purse A went up by 200 every day for 7 days a week. 7*200 would be 1400 so you add that to the money from today and get 2400. Purse B somehow got from 1 penny to 64 in 7 days. The rule on this is to multiply by 2 every day. 1,2,4,8,16,32 and 64. have fun with your magic :3

Answer: the area of a figure is 85.13 in²

Step-by-step explanation:

The area of a figure S consists of the area of a semicircle S₁ and the area of a parallelogram S₂

$\displaystyle\\S_1=\frac{\pi D^2}{4*2} \\\\S_1=\frac{\pi (8)^2}{8} \\\\S_1=\frac{64\pi }{8} \\\\S_1=8\pi \\\\S_1\approx25.13\ in^2\\\\S_2=10*6\\\\S_2=60\ in^2\\\\Thus,\\\\S=25.13+60\\\\S=85.13\ in^2$

B(n)=1 (-2)^n-1 What is the 4th term in the sequence

zzz [600]

Answer:

The fourth term of the sequence B(4) =-8

The sequence is 1,-2,4,-8...

Step-by-step explanation:

Explanation:-

Given that the sequence

B(n) = 1(-2)ⁿ⁻¹

Put n=1

B(1) = 1(-2)¹⁻¹ = 2⁰ =1

Put n=2

B(2) = 1(-2)²⁻¹ = (-2)¹ =-2

Put n=3

B(3) =1(-2)³⁻¹ = (-2)² =4

Put n=4

B(4) = 1(-2)⁴⁻¹ =(-2)³ =-8

The sequence

1,-2,4,-8...
