Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below. parabolic func
storchak [24]

Answer:

0

Step-by-step explanation:

The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:

Already with the figure we can solve the question.

We have that the average exchange rate in this case would only take the normal slope between those 2 lines

. Furthermore we know that the slope (m) is given by:

m = (y2-y1) / (x2 - x1)

From the graph we have to:

y2 = 0

y1 = 0

x2 = 5

x1 = 3

we replace:

m = (0-0) / (5 - 3)

m = 0

Therefore the average rate is 0.

A family went out to eat. Below is the number of coen dogs tbat each of the four people ate. Find the mean absolute deviation (m
Alexxandr [17]

Answer:

1.25

Step-by-step explanation:

Give the data:

X : 1 1/2 ___ 0 _____ 4 ______ 2 1/2

Mean absolute deviation (MAD) :

Σ|x - xbar| ÷ n

xbar = Σx/ n

Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8

xbar = 8/4 = 2

|x - xbar| :

|1 1/2 - 2|= 1/2

|0 - 2| = 2

|4 - 2| = 2

|2 1/2 - 2| = 1/2

Therefore,

MAD = (1/2 + 2 + 2 + 1/2) / n

MAD = 5/4

MAD = 1.25

If BD = 12x + 36
And BD = BC +CD = 3 + 1 = 4
BC = (12x + 36)/4 x 3
= 12(x+ 3) /4 x3
= 3(x+3) x 3
= 9x + 27
Likewise,
FE = 12(x + 3) /3 x 1
= 4x + 12

Area = 1/2 x (BC + FE) x DE
= 1/2 x (9x + 27 + 4x + 12)x (x+1)
= 1/2 x (13x + 39) x (x +1)
= 1/2 x 13x2 + 52x + 39


Hope this helps,

You are traveling 160 miles and it takes you 2.5 hours to get there what was your average speed
Anna35 [415]

The speed is 64 miles per hour

Step-by-step explanation:

Lets define speed first.

"Speed is the distance per unit time"

Speed is denoted by s.

Given

Distance = d = 160 miles

Time  = t = 2.5 hours

Speed = \frac{Distance}{Time}\\s = \frac{d}{t}\\\\s = \frac{160}{2.5}\\\\s = 64\ miles\ per\ hour

Hence,

The speed is 64 miles per hour

Keywords: Speed, distance
