Find (f • g)(2) f(x)= 6x g(x)= 2x + 2 (f • g)(2)=

Mathematics

brilliants [131]3 years ago

Answer:

Step-by-step explanation:

Another way to state the composition of functions is, in this case, f(g(2)).  Which means we will evaluate the g function at an x value of 2, then take that solution and sub it into the f function for x.

g(2) = 2(2) + 2 and

g(2) = 6.  Now take that and sub it into f for x:

f(6) = 6(6) and

f(6) = 36

f(g(2)) = 36

Can someone help me with this ?
Anastasy [175]

Answer:

11 inches

Step-by-step explanation:

We want to work out the radius of the cylinder in inches so we have to utilise the volume of a cylinder formula which is

Volume  = π × r² × h

Where "r" is the radius and "h" is the height

→ First substitute the value into the formula

121 π = π × r² × 1

→ We can divide both sides by π to get rid of it

121 = r² × 1

→ We should divide both sides by 1 to isolate r²

121 = r²

→ Now, we can square root both sides to find the value of the radius

11 = r

→ So the radius of the cylinder is 11 inches

The formula for converting Celsius temperatures to Fahrenheit temperatures is a linear equation. Water freezes at 0°C, or 32°F a
BlackZzzverrR [31]

Answer:

The formula y = mx + b sometimes appears with

different symbols.

For example, instead of x, we could use the

letter C. Instead of y, we could use the letter F.

Then the equation becomes

F = mC + b.

All temperature scales are related by linear

equations. For example, the temperature in

degrees Fahrenheit is a linear function of degrees Celsius.

Water freezes at: 0°C, 32°F

Water Boils at: 100°C, 212°F

Hope this helps!

What is 160,656 round to the nearest hundred thousand
Olegator [25]
We can round <span>160,656 to 200,000.</span>
Because 160,656 is more nearest to 200,000 than 100,000, a the second digit after 1 is 6 which is greater than 5 and close to 10 than 1. if it is less than 5, for example if the number is 140,656 then the number will be rounded to 100,000 as that one is more closest than 200,000.
But here 160,656 is rounded to 200,000.

Omar's gas tank is 1/10 full. After he buys 6 gallons of gas, it is 2/5 full. How many gallons can Omar's tank hold?
castortr0y [4]
1/10x + 6 = 2/5x
6 = 2/5x - 1/10x
6 = 4/10x - 1/10x
6 = 3/10x
6 / (3/10) = x
6 * 10/3 = x
60/3 = x
20 = x <=== the gas tank can hold 20 gallons
