Answer:
-0.7548
Step-by-step explanation:
1. In this solution , I found out the approximation values of x by using the Newton's Method.
The initial value i.e x0=-1.
by using the x0 value find the next approximation x1 value.
Here two functions f(x) and g(x) are given.
we have to calculate h(x) = f(x) - g(x)
we know
Xn+1 = Xn - [ f(Xn) / f'(Xn) ]
by using above formula we will get the x1 value as
x1 = -0.83333

2. we have to find the approximate values of x until their successive values differ by less than 0.001.
By following the above steps,we get
x2 = -0.7643988
x3 = -0.755026
x4 = -0.7548
the difference of x3 and x4 is i.e = 0.000148
Hence x value is = -0.7548

Answer:
what do u need help with?
Step-by-step explanation:
Answer:
-21 < 3x < -6
OR -6 > 3x > -21
Step-by-step explanation:
Take a part each section of the word form. Translate each section into algebraic form (numbers and symbols) and put the sections back together.
"Three times x": 3x A number and variable together multiply
"is less than -6": < -6
"and greater than -21": > -21
When writing that a number is > or <, you can also write the number on the other side, change the symbol, and it will mean the same thing.
< -6 is the same as -6 >
> -21 is the same as -21 <
<u>The number remains on the same open or closed side of the symbol.</u>
The problem tells use that "3x" is between -21 and -6. Put the sections back together, but write 3x in the middle.
-21 < 3x < -6
You can also write:
-6 > 3x > -21
You can write them either way, but some teachers prefer smaller number to bigger number from left to right.
Answer:
About 36%.
Step-by-step explanation:
The formula for the rate of return on investment is the total value minus the initial cost divided by the initial cost.
The total value is $1,500. The initial cost is $1,100.
(1,500 - 1,100) / 1,100 = 400 / 1,100 = 4 / 11 = 0.363636363636
So, Dean's rate of return on investment is about 36%.
Hope this helps!
No. It’s A. There are 8 km per 5 miles. How many Miles are in 120 km? In other words, 120 km/ x miles. Find x. You cross multiply giving you 8x=600. Divide by 8 on each side. Giving you x=75. So your answer is A
