Mathematics

rusak2 [61]3 years ago
3 0

Step-by-step explanation:

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

A=2\pi rh

or

A=2\pi \times r\times h

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.

Let f(x)=x^2+2 and g(x)=2x,find (fog)( x)
Artist 52 [7]

Answer:

<h2>(fog)( x) = 4x² + 2</h2>

Step-by-step explanation:

f(x) = x² + 2

g(x) = 2x

To find (fog)( x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)

We have

(fog)( x) = ( 2x)² + 2

We have the final answer as

<h3>(fog)( x) = 4x² + 2</h3>

Hope this helps you

Answer:

  all real numbers greater than or equal to –3

Step-by-step explanation:

|x| has a range of all real numbers greater than or equal to zero, so f(x) = |x|-3 will have a range of ...

In the 75th Congress (1937−1939) there were in the Senate 75 Democrats, 17 Republicans, and 4 members of other parties. Suppose
ira [324]

Answer:

42 Democrats members

12 Republicans members

2 other parties members

Step-by-step explanation:

We know that there are a total number of voters of

  • 75 (democrats)+17 (Republicans)+ 4( Other parties)=  96 voters

And we know that the bill has passed with 16 nore votes in favor that against, so let's calculate how many votes in favor of the bill we have:

  • 96 Votes = F (votes in Favor)+ A (votes against)

also: F= A+16= A = F-16, so:

  • 96= F+A= F+F-16 => F= 56 votes in favor of the bill

Thos 56 votes are the sum of the votes in favor from all the parties:

56 = D (votes in favor of democrats)+R ((votes in favor of Republicans)+OTH (votes in favor of other parties)

=> 56= D+R+OTH (A)

also democrat's votes in favor are three times the sum of non-democrat's votes in favor:

  • D= 3*( R+OTH) => OTH= D/3-R

and we have 30 more democrats thar republicans voting in favor:

  • D= R+30 => R=D-30

if we replace in the (A) formula:

56 = D+R+OTH => 56= D+D-30+D/3-D+30 =>

  • 56=4/3*D => D=42 (DEMOCRATS VOTES IN FAVOR)
  • R= D-30 => R= 12 (REPUBLICAN VOTES IN FAVOR)
  • OTH= D/3-R= 14-12= 2 (OTHER PARTIE'S VOTES IN FAVOR)

what is the function rule for the transformed with vertical stretch by a factor of 2 and translated down 6
SCORPION-xisa [38]

Answer: Thus, the equation of a function stretched vertically by a factor of 2 and then shifted 3 units up is y = 2f (x) + 6, and the equation of a function stretched horizontally by a factor of 2 and then shifted 6 units left is y = f ( (x - 6)) = f ( x - ). Example: f (x) = 2x2.
