Okay. I'll use a formula that my math teacher taught me.

3400(1-0.07)^15
3400(0.93)^15
3400(0.33670086205)
1144.78293098 ( which rounds to about 1145 square km )

Answer:

1144.78 Km^2

Step-by-step explanation:

If the forest covers an area of 3400 km^2 and it decreased by 7%, the new area covered after a year will be equal to 3400 less the product of 3400 and 7%

= 3400 - 7% * 3400

= 3400 (1 - 0.07)

After the second year, the area becomes

= 3400 (1 - 0.07) - 7% * 3400 (1 - 0.07)

= 3400 (1 - 0.07)(1 - 0.07)

= 3400 (1 - 0.07)²

Following this pattern, the area after 15 years

= 3400 (1 - 0.07)^15

= 1144.782931 km^2

(3,y) (1,4) m= -2 what is the value of y if the line through the two given points is to have indicated slope

riadik2000 [5.3K]

Answer:

y=0

Step-by-step explanation:

The equation for the slope is

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

-2 = (4-y)/(1-3)

-2 = (4-y)/-2

Multiply each side by -2

4 = 4-y

Subtract 4 from each side

4-4 = 4-y-4

0 = -y

0=y

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "

Nikitich [7]

The table is proportional and the constant of proportionality is 1.5

Step-by-step explanation:

Proportional relationships are relationships between two variables

where their ratios are equivalent

One variable is always a constant value times the other
The relation between the two variables represented graphically by a line passes through the origin point

The table:

→ x : 0 : 2 : 4 : 6

→ y : 0 : 3 : 6 : 9

To prove that y ∝ x find the ratio between each value of y with corresponding value of x

∵ $\frac{3}{2}=1.5$
