Answer:

Answer:

when you multiply a whole number by itself it will obviously get bigger.

4 to the 2nd power equals 16 because 4x4 = 16

if you were to multiply a smaller number though, it wouldn't get as big.

Each number you put to the same exponent will not get bigger at the same rate since each number isnt being multiplied by the same thing.

ex. 4 and 6 are raised to the second power both dont get multiplied by the same number 4 is multiplied by 4, and 6 by 6, therefore the bigger the number the bigger it grows.

Fractions get smaller for this reason when you have the fraction 2/3 raised to the second, both numbers must be raised. 2 to the second equals 4 while 3 to the second is 9.

1/2 to the second would then equal 1/4 since 1 to the second equals 1 and 2 to the second equals 4.

6.79 * 10 to the 3rd power

It's a written question. Can I have help please?

6.79*10^3

To make this the simplified (or whole) number, we need to move the decimal to the right 3 places.

What is a sampling distribution?

A sampling distribution is a probability distribution of a statistic obtained through a large number of samples drawn from a specific population. The sampling distribution of a given population is the distribution of frequencies of a range of different outcomes that could possibly occur for a statistic of a population.

Step-by-step explanation:

8z = 112

=14

d/14 = 7

=98

f/28 = 24

=672

Write the equation for each transformation of f(x)= |x| described below. a. translate left 9 units, stretch vertically by a factor of 5, and translate down 23 units.

b. translate left 12 units, stretch horizontally by a factor of 4, and reflect over the x-axis.

need steps don't understand how to do!

Okay, original equation of an absolute value function is:

a. f(x) = a |x-h| + k

a is the stretch or shrink

h is horizontal movement (watch the negative!!)

k is vertical shift

Translate left 9 units means horizontal shift so the h changes. When you move to the left, the numbers become negative so y = a|x-(-9)| + k which becomes

y = a|x+9| + k Then the vertical stretch of 5 becomes y = 5|x+9| + k And then a translation down 23 units means a negative shift down (which is your vertical shift) so:

f(x) = 5(x+9) - 23

b. translate left 12 units meaning a negative horizontal shift. y = a|x-(-12)| + k

so then it becomes y = a|x+12| + k

a stretch horizontally by 4 is your a, so y = 4|x+12| (you can just forget about the k since there is no vertical shift so your k = 0)

a reflection over the x-axis means that your horizontal axis is taken and folded and the reflection from the graph is your new graph. So basically, the whole equation becomes negative.

y = -4|x+12|

a. f(x) = a |x-h| + k

a is the stretch or shrink

h is horizontal movement (watch the negative!!)

k is vertical shift

Translate left 9 units means horizontal shift so the h changes. When you move to the left, the numbers become negative so y = a|x-(-9)| + k which becomes

y = a|x+9| + k Then the vertical stretch of 5 becomes y = 5|x+9| + k And then a translation down 23 units means a negative shift down (which is your vertical shift) so:

f(x) = 5(x+9) - 23

b. translate left 12 units meaning a negative horizontal shift. y = a|x-(-12)| + k

so then it becomes y = a|x+12| + k

a stretch horizontally by 4 is your a, so y = 4|x+12| (you can just forget about the k since there is no vertical shift so your k = 0)

a reflection over the x-axis means that your horizontal axis is taken and folded and the reflection from the graph is your new graph. So basically, the whole equation becomes negative.

y = -4|x+12|

If f(x) = 5x, what is f–1(x)?

When you are finding an inverse of a function, you switch the x and the y and solve for the new y. Our y = 5x, when switching x and y will be x = 5y. Now we have to find the new y. Dividing both sides by 5 we get . The really cool thing about functions that are inverses of each other is that their coordinates, (x, y) are switched to. If a point (1, 2) is on f(x), the point (2, 1) is on the inverse. And they always reflect through the line y = x. Just a bit of info.

Function 1: y = 4x + 5 Function 2: The line passing through the points (1, 6) and (3, 10).

Which of these functions has the greater rate of chang

Answer: function 1

Rate of change of function 1:

Following the format of y=mx+c, the rate of change should be m, so, the rate of change for function 1 = 4

To find the gradient (rate of change):

The two points the line passes through are (x1, y1) and (x2, y2), which in this case is (1, 6) and (3, 10)

(Doesn't matter which is which but you need to make sure that once you decide which is which, you stick to it)

To calculate the gradient, you substitute these values following (y1 - y2)/(x1 - x2)

Gradient of function 2 = (10 - 6)/(3 - 1)

= 2

Therefore, since 4 > 2, rate of change of function 1 > rate of change of function 2.

Rate of change of function 1:

Following the format of y=mx+c, the rate of change should be m, so, the rate of change for function 1 = 4

To find the gradient (rate of change):

The two points the line passes through are (x1, y1) and (x2, y2), which in this case is (1, 6) and (3, 10)

To calculate the gradient, you substitute these values following (y1 - y2)/(x1 - x2)

Gradient of function 2 = (10 - 6)/(3 - 1)

= 2

Therefore, since 4 > 2, rate of change of function 1 > rate of change of function 2.
