If 2x – 1 is a factor of 16x4<br> 24x3 + 2x + f, find f.
Nastasia [14]

Answer:

f = -5

Step-by-step explanation:

If 2x – 1 is a factor of 16x4 + 24x3 + 2x + f, find f.

If 2x - 1 = 16x⁴ + 24x³ + 2x + f, find f.

2x - 1 = 0

2x = 1

x = 1/2

Hence

f(1/2) = 16(1/2)⁴ + 24(1/2)³ + 2(1/2) + f

= 16(1/16) + 24(1/8) + 1 + f

= 1 + 3 + 1 + f

= 5+ f

f = -5

What is the difference between the mean and the median of the following distribution?
natulia [17]
The definition of mean, is to add up all the numbers and divide it by how many numbers there are. So, in this case the mean would be 1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9 = 86. You would then take 86 and divide that by 21, and you would get 4.0
The definition of median states to find the middle of the numbers. So the median would be 4. 
So you would just take 4 - 4 = 0. 

0 would be correct.

Using the graph provided, find f(x)=2
natali 33 [55]

Answer:

so x=3

Step-by-step explanation:

f(x) = 2

We want to find the x value when y =2

Going across where y = 2

Then go down to find the x value x=3 when y = 2

f(3) =2

so x=3

Solve each problem using a formula for perimeter or area<br> ill give brainliest!!!!!
Karolina [17]

Answer:

12) s=\frac{p}{5}

13) A=wh

14) p=a+b+c

15) A=\frac{bh}{2}

16) p-b-c=a

Step-by-step explanation:

12) \frac{p}{5} =\frac{5s}{5}

13) \frac{A}{h}=W (multiply both sides by h)

14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value

15) Divide both sides by 2

16) take b + c to the other side of the equation where it becomes -b-c
