60 minutes / 18 = 3.3333 repeating That’s how many of his 18-minute intervals are in 1 hour
Multiply that by the 3 miles he can run in each 18 minute interval
3.33333 x 3 = 10mph

For what value of k, -4 is a zero of polynomial x2-x-(2k+2)?
bekas [8.4K]
Hmm
well, um
if -4 is  a zero then if we subsitute -4 for x, we should get 0

so
0=(-4)²-(-4)-(2k+2)
0=16+4-2k-2
0=18-2k
2k=18
divide by 2
k=9

k=9
the value k is 9

Agata [3.3K]

Answer:

Maximum =  756

Minimum =  600

Step-by-step explanation:

A square is a shape that has the large areas of a defined perimeter out of available rectangles. It implies they want the two parentheses to be as similar in value. as a result, to establish the maximum value of P.

And to establish the minimum value, to have the greatest difference for them. 1 + 2 + 3 ... +10=55, which wasn't even but which can be split as similarly as possible into 27 and 28 which have a product of 756. In this question it can be done in a variety of ways, one of which is:

(1 + 3 + 5 + 8 + 10) ×  (2 + 4 + 6 + 7 + 9) = 756

At the very least, the biggest difference can be created if one term is made of the smallest numbers, while the other full of the highest, or:

(1 + 2 + 3 + 4 + 5) × (6 + 7 + 8 + 9 + 10)=600

Create a table and graph y=x+1 demos<br>​
DerKrebs [107]

Answer:

The table will be:

x          y=x+1

1            2

2           3

3           4

4           5

5           6

The graph is shown in figure attached.

Step-by-step explanation:

We need to create table and graph the expression: y=x+1

Table is made, such that we take value of x and find value of y

You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.

So our table will be:

x          y=x+1

1            2

2           3

3           4

4           5

5           6

Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.

The graph is shown in figure attached.
