Answer:

x=1

Step-by-step explanation:

Question says to use a graphing calculator or online application to find the solution to 3-x = x^3 + x to the nearest tenth.

So we will create two equations y = 3-x and y = x^3 + x using each sides of the given equation.

Now we graph both equation using some online calculator or graphing calculator. I'm going to use Desmos calculator.

Intersection point of both graphs will give the solution.

From graph we see that intersection point is at (1,2).

We are looking for value of x only.

Hence final answer is x=1

For the function f(x) = -3(x-1) find f(0)
d1i1m1o1n [39]

Answer:

f(0) = 3

Step-by-step explanation:

f(x) = -3( x - 1 )

f(0) = -3( 0 - 1 )

f(0) = -3 ( -1)

f(0) = 3

What is the measure of angle E, in degrees?
Leni [432]

The answer is 84 degrees because d and f both are 48 degrees so that adds up to 96. So that means you add 84 plus 96 which is 180 so the answer is 84 degrees.

What is the volume?<br> 2 mm<br> 8 mm<br> 4 mm<br> cubic millimeters
shutvik [7]

Answer:

64 mm³

Step-by-step explanation:

I am assuming there was a photo to go with this problem

However the general formula to find volume is usually V = l×w×h

  • It does not matter which measurement is which because they all get multiplied together.
  • However assigning a name to each unit of measurement we will denoted the length (l) as 2 mm, the width (w) as 8 mm, and the height (h) as 4 mm
  • Plugging these values into the formula we get: V = (2)(8)(4) = 64 mm³

I need help with question 9
makvit [3.9K]

Answer:

f(x)=0.17x+3.00

f(60)=0.17(60)+3.00

f(60)=10.20+3

f(60)=13.20

1 hour will cost $13.20

Step-by-step explanation:

I found the difference in minutes between the given values and the difference in cost between the given values. Between 8 minutes and 25 minutes is 17, and between 25 and 40 is 15 minutes. The difference of $7.25 and $4.36 is $2.89, and the difference between $7.25 and $9.80 is $2.55. I then divided2.89 by 17 and 2.55 by 15 and both resulted in $0.17/minute. I them multiplied 8 minutes by $0.17 toget $1.36. I subtracted that from the cost given for 8 minutes to get $3.00. The $3.00 is the initial charge, or b in slope-intercept form with m=0.17. Plug in 60 for x to find the cost of an hour.
