Answer:

489 × 10-11.5

Step-by-step explanation:

In order to write number 0.00000000004589 in scientific notation we need to move the decimal point from its current location (black dot) to the new position (red dot).

0.00000000004.589

So, we need to move decimal point 11 places to the left.

This means that the power of 10 will be negative 11.

Now we have that the

Number part = 4.589 and

Exponent part = -11

So, the solution is:

489 × 10-11.5

Please help, i can't figure this out and im ready to pull my hair out!!!

Answer:

I'm sorry I don't know the equation, but she walks 3 mph.

Step-by-step explanation:

We know that the answer is asking for speed, which needs both distance and time, so we also need both. Which is where the 9 mph is used. 9 mph means its a difference. b means biking mph, w means walking mph, sooo ----->>> b=w+9, and the difference in the 1st equation is 36, which means the first equation is 4 times larger than the b=w+9, so she walked 48 miles, as well as walked 12 miles in 4 hours. Divide then distances by 4, and you get 12 miles and 3 miles in one hour. Or 12 mph & 3 mph, which fits into 12=3+9. So she walks 3 miles per hour.

3, 9, 10, 5, 8, 5, 9, 11, 10, 3, 10 Find the mean of the data.
slava [35]

Answer:

7.55

Step-by-step explanation:

An arithmetic mean is the average value of all the data points.

In order to find the average value, you add all the data points then divide the resulting sum by the number of data points there are.

The sum of all data points:

3 + 9 + 10 + 5 + 8 + 5 + 9 + 11 + 10 + 3 + 10 =

83

The number of data points:

3, 9, 10, 5, 8, 5, 9, 11, 10, 3, 10

1,2,3,4,5,6,7,8,9,10, 11 = 11 data points

Average value/ Mean:

83 / 11 = 7.545454545454 = rounded to 7.55

Which of the following accurately shows the range of the function defined below?
il63 [147K]

Answer: The answer is (b) (2, ∞)

Step-by-step explanation:  We are given a function f(x) in the figure and we are to select out of the given options that accurately shows the range of the function defined.

\textup{For }x < 0, \textup{we have}~f(x)=3.

\textup{For }0\leq x

\textup{For }x\geq 2,\textup{ we have }f(x)=\dfrac{1}{2}x+5\geq 5.

Therefore, the range of the function f(x) will be greater then or equal to 2. So, the range will be [2, ∞).

Thus, the correct option is (b) (2, ∞).

Zarrin [17]

if y=367

then you need to figure out this:

367=5x+287

so remove 287 from 367

367-287=80

Then divide by 5

80/5=16

so, x=16
