Jordan spends 50 minutes on his homework.

Step-by-step explanation:

Given,

Time spent on Maths homework = 11 minutes

This represents the 22% time of his total homework.

Let,

x be the total time spent on homework.

22% of x = 11

\frac{22}{100}*x=11\\0.22x=11

Dividing both sides by 0.22

\frac{0.22x}{0.22}=\frac{11}{0.22}\\x=50

Jordan spends 50 minutes on his homework.

Answer:

a_n=-3(3)^{n-1} ; {-3,-9, -27,- 81, -243, ...}

a_n=-3(-3)^{n-1} ; {-3, 9,-27, 81, -243, ...}

a_n=3(\frac{1}{2})^{n-1} ; {3, 1.5, 0.75, 0.375, 0.1875, ...}

a_n=243(\frac{1}{3})^{n-1} ; {243, 81, 27, 9, 3, ...}

Step-by-step explanation:

The first explicit equation is

a_n=-3(3)^{n-1}

At n=1,

a_1=-3(3)^{1-1}=-3

At n=2,

a_2=-3(3)^{2-1}=-9

At n=3,

a_3=-3(3)^{3-1}=-27

Therefore, the geometric sequence is {-3,-9, -27,- 81, -243, ...}.

The second explicit equation is

a_n=-3(-3)^{n-1}

At n=1,

a_1=-3(-3)^{1-1}=-3

At n=2,

a_2=-3(-3)^{2-1}=9

At n=3,

a_3=-3(-3)^{3-1}=-27

Therefore, the geometric sequence is {-3, 9,-27, 81, -243, ...}.

The third explicit equation is

a_n=3(\frac{1}{2})^{n-1}

At n=1,

a_1=3(\frac{1}{2})^{1-1}=3

At n=2,

a_2=3(\frac{1}{2})^{2-1}=1.5

At n=3,

a_3=3(\frac{1}{2})^{3-1}=0.75

Therefore, the geometric sequence is {3, 1.5, 0.75, 0.375, 0.1875, ...}.

The fourth explicit equation is

a_n=243(\frac{1}{3})^{n-1}

At n=1,

a_1=243(\frac{1}{3})^{1-1}=243

At n=2,

a_2=243(\frac{1}{3})^{2-1}=81

At n=3,

a_3=243(\frac{1}{3})^{3-1}=27

Therefore, the geometric sequence is {243, 81, 27, 9, 3, ...}.

Explain why kilobytes and terabytes would not be descriptive measurements for the amount of space on an average USB storage devi
bonufazy [111]

Answer:

The storage capacity of the USB is far greater than Kilobytes, but less than a Terabyte.

Step-by-step explanation:

The USB storage device has a capacity of (8 - 256) GB. This implies that the USB has the capacity to store files size from 8 Gigabytes to 256 Gigabytes.

8 Gigabytes ≅ 8 000 000 000 bytes

256 Gigabytes ≅ 256 000 000 000 bytes

Kilobytes would not be an appropriate descriptive measurement of the storage capacity of the USB because 1 kilobyte ≅ 1 000 bytes. Thus;

8 Gigabytes ≅ 8 000 000 kilobytes

256 Gigabytes ≅ 256 000 000 Kilobytes

The storage capacity of the USB is far greater than Kilobytes.

Terabytes can not be used to describe the measurement f the USB because; 1 Terabyte ≅ 1 000 000 000 000 bytes

Thus, the storage capacity of the USB is less than 1 Terabyte.
