126b + 67
Product is multiplication, so multiply 126 and b. Then 67 more, aka add
Answer:
Step-by-step explanation:
We have been given two functions as 
and 
. We are asked to show that both functions are inverse of each other algebraically and graphically.
Let us find inverse function of as:
Interchange x and y values:
Using log property 
, we will get:
Using log definition; If 
, then 
, we will get:
Therefore, we can see that function is inverse of function .
We can see that both functions are symmetric about line 
, therefore, both functions are inverse of each other.
Answer:
y-intercept: (0,-4)
x-intercept: (-16,0)
Step-by-step explanation:
To solve for X, Substitute 0 for Y and continue.
To solve for Y, Substitute 0 for X and continue.
Step-by-step explanation:
use the midpoint formula
-3+-7/2, 8+-6/2
(-5, 1)
<span>Let each side perpendicular to the river be
"x".
Then the side parallel to the river is "2400-2x".</span>
The function would be:
<span>A(x) = x(2400-2x)
</span>
And it would be: A(x) = 2400x - 2x^2
To solve the equation:
<span>
You have a quadratic with a = -2 and b = 2400
</span>
Maximum Area happens where:
x = -b/2a
= -2400/(2*-2)
<span>= 600 ft. (width)
</span>
To find the length it will be:
<span>= 2400-2x = 2400-2*600 = 1200 (length)</span>
