Answer:

She is not correct

Step-by-step explanation:

An array (in context of multiplication) is the representation of objects in rows and columns with same number of elements in each row and in each column.

e.g

0 0 0

2 2 2

3 3 3

is an array.

The total numbers(number of objects) in an array must be divisible by the number of rows and by number of columns.

According to the statement:

Paula can draw an array with a total of 17 counters placed in 3 rows. According to the definition of array, the total number of counters must be divisible by number of rows/columns to form the array. Since, in this case, the total number of counters(17) is not divisible by number of rows(3), the array cannot be formed.

Thus we can conclude that Paula is not correct. An array could have been formed if there were 18 counters in total.

For the graph x = -42 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your
tamaranim1 [39]
X - 42 is a straight vertical line passing through  -42 on the x-axis ( point -42,0)
so the slope is infinite .
Another line with same slope  and parallel to it would be x = 36.

A horizontal like with slope 0  is perpendicular to it  It would have equation y  any number  so y = 6 would be an example.

Factor each trinomial.<br>1. x2 + 7x + 10​
Pani-rosa [81]

Answer:

I dont know about you, but my teacher taught me to use MAN

M= 10 (the c value)

A= 7 (the b value)

N= +5, +2 (two numbers that multiply and add to give you 10 and 7. For example, 5 times 2= 10 and 5 plus 2 = 7)

ANSWER: (x+5)(x+2)

if you have any questions let me know.

Estimate the rate of change of the graphed function over the interval -4 &lt;_ x &lt;_ 0
dezoksy [38]

Answer:

  0.2071

Step-by-step explanation:

It looks like the graph is of the function ...

  y = √(x +8) -2

We know that (-4, 0) is one point on the graph. The other point of interest is at x=0, where y = √8 -2 ≈ 0.8284.

The average rate of change on the interval is then ...

  m = (0.8284 -0)/(0 -(-4)) = 0.2071

The average rate of change on the interval is about 0.2071.

_____

<em>Rougher estimate</em>

The graph goes through the points (-4, 0) and (1, 1), so has a slope of 1/5 = 0.2 on the interval [-4, 1]. We know the graph does not go through (0, 1), so the slope is not as high as 1/4 = 0.25. The curve is concave downward, so the average slope will be higher than 0.2, but we aren't sure how much higher.

A reasonable estimate of the rate of change on the interval is "a little more than 0.2, but less than 0.25."
