And of course, I must thank despicable me 1,2, and 3 for teaching me everything i know.

I really appreciate this. Honestly, this really warmed my heart to be able accept this award from you today.

Find the interval(s) over which the function is decreasing

son4ous [18]

Answer : (0,3) U (3, ∞)

We need to find the interval(s) over which the function is decreasing

We look at the intervals of x where the graph is decreasing

Decreasing interval of the graph is the part where the graph goes down

We look at the part where the graph changes direction

In the middle inverted U shaped graph , the graph changes direction and start decreasing at x=0

the graph is decreasing till x=3

so first decreasing interval is x=0 to 3. we write it as (0,3)

After x=3 the graph starts decreasing and it goes to infinity

So the second decreasing interval is 3 to infinity . We write it as (3, ∞)

Now combine both intervals by a 'U' union

(0,3) U (3, ∞)

Graph this function: y = 2x

77julia77 [94]

Graph is attached below.

Step-by-step explanation:

We have to graph function y = 2x,

From equation, we can see a linear relationship between the values of x and y. This equation shows that the value of y is double than the value of x.

For example,

x = 0

y = 2(0)

y = 0

So, point would be (0,0)

x = 1

y = 2(1)

y = 2

So, point would be (1,2)

x = 3

y = 2(3)

y = 6

So, point would be (3,6)

x = -1

y = 2(-1)

y = -2

So, point would be (-1,-2)

x = -3

y = 2(-3)

y = -6

So, point would be (-3,-6)

By matching these points, a linear graph can easily be drawn. I have also attached the graph pic below.

For a recent season in college football, the total number of rushing yards for that season is recorded for each running back. Th

TiliK225 [7]

Answer:

Step-by-step explanation:

From available information

Mean = 790

1 running back = 1637 yards

Standard deviation above mean = 2.42

Using formula

z =( x - mean)/sd

2.42 = (1637-790)/sd

2.42 = 847/sd

We cross multiply

2.42sd = 847

Divide through by 2.42

Sd = 847/2.42

Sd = standard deviation = 350

So our answer is 350 and therefore option c.
