Answer:
Step-by-step explanation:
Area of a rectangle = Length x Breadth.
Area= L x B
We are told the length is twice the breadth.
You can write this as :
Length = 2 x Breadth
L = 2B
If you put that into the area formula at the beginning, we get:
Area = L x B
Area = 2B x B = 
They also told us that the area of the field is 3200 square meters. So,
Area = = 3200
Divide both sides by 2
= 
Now to solve for B we need to square root both sides.
= 40
So now we know the Breadth is 40meters
Remember earlier we said Length = 2 x Breadth
Cost of fencing the field = 2L + 2B
Cost of fencing the field = 2 x 80 + 2 x 40 = $240
The domain of the exponential function is -∞0 < x < ∞
<h3>What is the domain of a function?</h3>
The domain of the function is the set of input values of the graph
<h3>How to determine the domain of the function?</h3>
The function is represented by the set of relation or ordered pairs on the graph
The graph is given as an attachment
From the attached graph, we have the following observation:
The curves of the exponential function end with arrows at both end
This means that the input values of the function extend indefinitely
i.e. from negative infinity to positive infinity
Hence, the domain of the function is -∞0 < x < ∞

Answer:
Step-by-step explanation:
(7+4)/2 = 11/2 = 5.5
(1-1)/2 = 0/2 = 0
(5.5, 0)
answer is C
I'm not 100% sure but I'm going to go with 12 as my answer. Because if you look at it, it's being multiplied by twos 7x2=14, 8x2=16 also if you look at it the rest of the numbers go the same way 2x2=4 2x4=8 2x3=6 but I'm not sure about the 7... but my answer will still be 12.
Simple,
x+7= 18-2x
you want isolate the variable, x, to find what it's value is...
x+7=18-2x
+2x +2x
Making it..
3x+7=18
still not done...finish isolating the variable...
3x+7=18
-7 -7
3x=11
=
Thus, your answer is, x=
.
