3x-30=0why does it equal 0 and how would I solve for it

Mathematics
1 answer:
agasfer [191]2 years ago
5 0

Answer: the reason why 3x - 30 = 0 is because x = 10

Step-by-step explanation:

3x - 30 = 0

first we try to get the value of x

so

3x = 30

x = 30/3

x = 10

so the reason why 3x - 30 = 0 is because x = 10

to confirm this

we substitute the value of x=10 into the equation

3x - 30 = 0

3*10 - 30 = 0

30 - 30 = 0

Use Newton’s method to approximate the indicated root of the equation correct to six decimal places. The positive root of 3 sin
MAXImum [283]

Answer:

x \approx 2.278863

Step-by-step explanation:

Required

The positive root of 3\sin(x) = x

Equate to 0

0 = x -3\sin(x)

So, we have our function to be:

h(x) = x -3\sin(x)

Differentiate the above function:

h'(x) = 1 -3\cos(x)

Using Newton's method of approximation, we have:

x_{n+1} = x_n - \frac{h(x_n)}{h'(x_n)}

Plot the graph of h(x) = x -3\sin(x) to get x_1 --- see attachment for graph

From the attached graph, the first value of x is at 2.2; so:

x_1 = 2.2

So, we have:

x_{n+1} = x_n - \frac{h(x_n)}{h'(x_n)}

x_{1+1} = x_1 - \frac{h(x_1)}{h'(x_1)}

x_{2} = 2.2 - \frac{2.2 -3\sin(2.2)}{1 -3\cos(2.2)} = 2.28153641

The process will be repeated until the digit in the 6th decimal place remains unchanged

x_{3} = 2.28153641 - \frac{2.28153641 -3\sin(2.28153641)}{1 -3\cos(2.28153641)} = 2.2788654

x_{4} = 2.2788654 - \frac{2.2788654 -3\sin(2.2788654)}{1 -3\cos(2.2788654)} = 2.2788627

x_{5} = 2.2788627 - \frac{2.2788627-3\sin(2.2788627)}{1 -3\cos(2.2788627)} = 2.2788627

Hence:

x \approx 2.278863

What does x equal? Plz hurry. First to answer correctly will be marked brainliest ASAP.
svet-max [94.6K]

Answer:

6.0

Step-by-step explanation:

This involves using SOH CAH TOA.

we use Sin as we want to find x (which is side O, and we are given H).

So we get sin37 = O/H

                          = x/10

so x = 10 sin 37 = 6.018... = 6.0 to the nearest tenth.

What is the soulution of -(-5-6x) = 4(5x+3)?
Fynjy0 [20]
You have to distribute the parentheses first. Since there is a negative sign in front of the parentheses, it counts as a negative 1. After you distribute you should get: -5+6x=20x+12, but that is not your final answer. After you add like terms: 17x=-17. Divide 17 on both sides: x=-1. X=-1 is your final answer.
