Answer:

2

Step-by-step explanation:

The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.

So we are going to need to corresponding y coordinates.

What y corresponds to x=1? y=3

What y corresponds to x=2? y=5

So we have the ordered pairs (1,3) and (2,5).

Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.

(2 , 5)

-(1  , 3)

-----------

1      2

The average rate of change is 2/1 or just 2.

Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.

Answer: Fourth option

m=2

Step-by-step explanation:

If we call m the average change rate of a function between x_1 and x_2, then, by definition:

m=\frac{f(x_2)-f(x_1)}{x_2-x_1}

In this case the function is the line shown in the graph. Then we look for the values of y = f (x) for x = 1 and x = 2

When x=1 then f(x)=3

When x=2 then f(x)=5

Therefore

m=\frac{5-3}{2-1}

m=\frac{2}{1}

m=2

a weather balloon is released and reaches a maximum altitude of 5000 meters.A week later, the balloon is recovered at 3750 metwr
dsp73

The change in altitude between the maximum height and the height at which the balloon was recovered is 1300 meters

<h3>How to determine the change</h3>

It is important to note that the maximum height is the peak altitude the balloon reached

To find the difference, we use the formula

Change = Maximum height - recovery height

Maximum height = 5000 meters

Recovery height = 3700 meters

Substitute the values

Change = 5000 - 3700

Change = 1300 meters

Thus, the change in altitude between the maximum height and the height at which the balloon was recovered is 1300 meters

For the function f(x) = 8x7, find f-¹(x).
Zanzabum

Answer:

f^-1(x)= \sqrt[7]{x} /8

Step-by-step explanation:

f(x)=8x^7

x^7=f(x)/8

x=\sqrt[7]{x} /8

f^-1(x)= \sqrt[7]{x} /8

Answer:

For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:

A = (1/2)*H*(X + Y)

with this we can complete the table.

a)

Here we know:

X = 7cm

Y = 11cm

H = 6cm

Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2

b)

Here we know:

X = 8 m

Y = 10 m

A = 126 m^2

Then:

126 m^2 = 0.5*H*(8m + 10m)

126 m^2 = H*9m

126 m^2/9m = H = 14m

Then the height of this trapezoid is 14m

c)

Here we know:

X = 5mm

H = 8mm

A = 72 mm^2

Then:

72 mm^2 = 0.5*8mm*(5mm + Y)

72 mm^2 = 4mm*(5mm + Y)

72mm^2/4mm = 5mm + Y

18 mm = 5mm + Y

18mm - 5mm = Y

13 mm = Y

Then the parallel side 2 is 13 mm long.
