I believe the answer is.

f(x) is a fancy way of saying y. So for now I will refer to y.

f(x)

y=3x+2+7x

g(x)

y=2x2-x-1

3x+2+7x+(2x2)-x-1 = f(x)+g(x)

Now lets add

10x+2+4-x-1=f(x)+g(x)

9x+5=f(x)+g(x)

A sports ball has a diameter of 27 cm. Find the volume of the ball. cm.) Round your answer to the nearest tenth if necessary.​
Anestetic [448]
To calculate the volume of a sphere you must use the formula
v=4/3pir^3

The radius (r) is half of the diameter
r=13.5

v=4/3pi13.5^3
v=10305.99

Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)

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.

A train is traveling at a constant speed of 90 miles per hour. How many feet does it travel in 10 seconds? Remember that 1 mile
Flauer [41]

Hi

1 mile = 5280 feet  

at  90 mile per hour, you have  5280 *90  = 475 200 feets  

an hour is  60*60 = 3600 second  

so in 1 second the train travel  :  475 200 /3600 = 4752 /36 = 132 feets

so in 10 seconds  :  132*10 = 1320 feets.
