Answer: D. 9.4 units

Explanation: We use the Pythagoras theorem because we know that it’s a right triangle and we have 2 lengths.

8^2+5^2= c^2

89=c^2
c= sqrt 89
c≈9.4 units

The maximum number of batches in the table is 9
So, 6 more batches than the maximum number of batches is 9+6=15
Also, we must see that there is a trend in the total number of cookies
As the batch increases by one, we can see that the total number of cookies increases by 16
Hence, the total number of cookies when she bakes 15 batches is
229+ 15x6 = 319

Need Help Finding average rate of change on a graph? I have a screenshot of the graph and the question
Katen [24]

Answer:

-3

Step-by-step explanation:

The average rate of change is the slope of the line that connects the points of interest. At x=-6, the point is (-6, 8). At x=-5, the point is (-5, 5).

I find it easy to refer to the graph to see that the point at x=-5 is 3 units down and 1 unit to the right of the point at x=-6. So the slope of the connecting line is -3/1 = -3.

If you want to find the same result analytically, you can compute ...

... ∆y/∆x = (y2 -y1)/(x2 -x1)

... = (5 -8)/(-5 -(-6))

... = -3/1 = -3

. Evaluate each expression given that X = -2, Y = 8 and Z = 4
Liula [17]
Hello:-
this(*)is counted as multiplication
1. 4*2 + (-2+8)
=8+(6)
=14
2. (-2)*2 + 4
= -4+4
=0
3. 8*4/-2
= -32/2 (as -ve sign cannot be in denominator)
= -16
4. -2*4/8
= -8/8
= -1
5. -2*8/4
= -16/4
= -4
therefore it is a. -4
I hope it will help u !!!!!!!!!
