1 square meter is 0.01 decameter in the table
So, 490 X 0.01 = 4.9 decameters

Hope I helped :)

The answer will be 4.9. =)

Since we know 1 metre is 0.01 dekametres, we can use this to answer the question!

We simply multiply 490 by 0.01. =)

The minimum and maximum temperature on a cold day can be modeled by the equation 2[x-6]+14=38 What are the min and max temperatu

SashulF [63]

Here are the steps to calculating the given equation:

Distribute 2 to x and 6: 2x-12+14=38
Group like terms: 2x+(-12+14)=38
Combine like terms: 2x+2=38
Subtract number on 'x' side: 2x+2-2=38-2
Simplify: 2x=36
Divide: 2x/2=36/2
Simplify: x=18
Label with correct terms:
I cannot do this because you did not provide sufficient information, I would need to know what the difference between the two, or if 'x' stood for one particular temperature. Hope that helped enough with what you provided.

Answer:

(4, 0)

Step-by-step explanation:

The circumference of a circle is $2 \pi r$ where r is the radius.

In this case, $2 \pi r = 10 \pi$ . Divide both sides of the equation by $2\pi$ to get

$r=5$

The center of the circle is on the x-axis, so the intercepts are 5 units to the left of the center and 5 units to the right of the center. The two intercepts are (-1-5, 0) and (-1+5, 0). The point that is on the positive x-axis is (4, 0).
