Answer:

f(x)=x²+1

f(f(x))=(x²+1)²+1

=x⁴+1+2x²+1

=x⁴+2x²+2

choose (2)

Use the digits 2,3,and 5 to create a fraction and a whole number with a product greater than 2
mylen [45]

Product is multiplication.

Since the answer needs to be greater than 2 either the fraction needs to be an improper fraction ( meaning the fraction would be greater than 1) or the whole number would need to be greater than 2.


One answer would be 5 x 2/3 = 3 1/3

Solve x in 2|x+ 6| + 9 = 19
xenn [34]
Answer: x=-1

Step by step:

2|x+6|+9=19

Subtract 9 from both sides.

2|x+6|=10

Divide both sides by 2

|x+6|=5

Use the definition of absolute value.

x+6=5

Subtract 6 on both sides

x=-1

Hope this helped! :)

Please help me find the area of each shaded segment and round the answer to the nearest tenth :)
Keith_Richards [23]
Hi there!

In order to solve, we need to use the formula for the area of a circle, and the angle given to find the area of the sector. Then, subtract the area of the triangle to find the area of the segment. We would use the equation : A = x/360 (pi * r^2) - 1/2(b * h). We need to plug in 90 for the angle measurement, 8 for the radius, and 8 for both the base and height. 

WORK:
A = 90/360 (pi * 64) - 1/2(64)
A = 1/4(64pi) - 32
A = 16pi - 32 = ~ 18.3ft^2

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

3/4 ÷ 5 1/2 please explain the steps
Mademuasel [1]
The easiest way to do it is to make the numbers into decimals.  All you need to do is divide them.

To convert 3/4 into a decimal just divide 3 by 4.

3 / 4 = .75

To get 5  1/2 into a decimal just ignore the 5 for now and divide the 1 by 2.

1 / 2 = .5

Now add the 5 back on and you have 5.5

So far you have converted the equation from (3/4) / 5 1/2 to .75 / 5.5

Now just divide .75 by 5.5

.75 / 5.5 = 1.136 with the 36 repeated
