Answer:

f(-2) = 3

Step-by-step explanation:

Given that,

f(x) = x + x + 7

We need to find the value of f(-2).

Put x = -2 in the given function.

f(-2) = (-2) + (-2) + 7

= -2-2+7

= -4+7

= 3

Hence, the value of f(-2) is equal to 3.

Answer:

For the part that contains organic matter your answer is, 35 negative result

For the part that does not contain organic matter your answer is, 60 positive result

Step-by-step explanation:

If we pay attention to the part that contains organic matter the total amount 700 and 665 is positive, so subtract them 700-665 to get 35 negative result

For the part that does not contain organic matter the total amount is 300, and 240 of it is negative, so subtract 240 from 300 to get 60 positive result

In this circle, the area of sector COD is 50.24 square units. The radius of the circle is units , and units.
maks197457 [2]

Let angle be alpha

\\ \rm\Rrightarrow Area=50.24

\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24

\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4

\\ \rm\Rrightarrow \alpha r^2=5760

\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}

\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer
