Megan rounded 366,458 to 370,000. To which place did Megan round the number?

Answers

Megan round the number in ten thousand place.

What is rounding off?

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

Megan rounded number 366,458 to 370,000.

Now,

Since, We know that;

When we round the number in ten thousand place then we look at the position of thousand. If the number is greater than 5 then we add 1 in ten thousand place and if the number is less than 5 then we can not do anything.

So, Megan round the number in ten thousand place.

Solve 8 x -22 = -7 (x+1)

Answers

Answer:

x = 1

Step-by-step explanation:

8x - 22 = -7 (x+1)

8x - 22 = -7x - 7

15x = 15

x = 1

8x - 22 = -7x - 7
Add -7 on both sides and you’ll get 15x - 22 = -7 add 22 on both sides and you’ll get 15x = 15 and you’ll get x= 1

Use the following graph of the function f(x) = 3x4 − x3 + 3x2 + x − 3 to answer this question: graph of 3 x to the fourth, minus x cubed, plus 3 x squared, plus x minus 3. What is the average rate of change from x = 0 to x = 1?

Answers

For this case we have the following function:
$f (x) = 3x ^ 4 - x ^ 3 + 3x ^ 2 + x - 3$
By definition we have that the average rate of change is given by:
$AVR = (f(x2)-f(x1))/(x2-x1)$
We evaluate the function for the given interval:
For x = 0:
$f (0) = 3 (0) ^ 4 - (0) ^ 3 + 3 (0) ^ 2 + (0) - 3f (0) = - 3$
For x = 1:
$f (1) = 3 (1) ^ 4 - (1) ^ 3 + 3 (1) ^ 2 + (1) - 3f (1) = 3$
Substituting values we have:
$AVR = (3-(-3))/(1-0)$
Rewriting we have:
$AVR = (3+3)/(1-0)$
$AVR = (6)/(1)$
$AVR =6$
Answer:
the average rate of change from x = 0 to x = 1 is:
$AVR =6$

Answer:

Average rat of change of function is 6 from x = 0 to x = 1.

Step-by-step explanation:

We are given a function:

$f(x) = 3x^4 - x^3 + 3x^2 + x - 3$

The attached image shows the graph for the given function.

Average rate of change of function =

$\text{Average rate of change} = \displaystyle(\delta y)/(\delta x) = (f(b)-f(a))/(b-a)$

Now we will evaluate f(1) and f(0).

$f(x) = 3x^4 - x^3 + 3x^2 + x - 3\nf(1) = 3(1)^4 - (1)^3 + 3(1)^2 + (1) - 3 = 3\nf(0) = 3(0)^4 - (0)^3 + 3(0)^2 + (0) - 3 = -3$

Putting the values, we get,

$\text{Average rate of change} = \displaystyle(f(1)-f(0))/(1-0)\n\n= (3-(-3))/(1-0) = (6)/(1) = 6$

Thus, the average rat of change of function is 6 from x = 0 to x = 1.

dominique drove home from work at an average speed of 36 miles per hour. if the distance from her house to her workplace is 5.4 miles, how long did her commute take?

Answers

Answer:

Dominique's commute took 9 minutes

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Since we are given 3 values with 1 variable, and this is a ratio problem we can use the Rule of Three technique to calculate how long her commute will take. The technique is shown in the picture attached below, but before we can use this technique we need to change the hours into minutes.

1 hour = 60 minutes

Now we can use the technique...

36 miles ⇒ 60 minutes

5.4 miles ⇒ x

$(5.4*60)/(36) = 9minutes$

Finally, we can see that it to Dominique's commute took 9 minutes.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Putting this into an equation would result:

5.4/x = 36

x = 5.4/36

x = .15 hour

.15 x 60 = 9 minutes

9 minutes is the answer
