The garden area is maximum when the enclosure is a square.
If a is the length of the side of the square then the length of the building is also a.
The perimeter length is 4a made up of 81+a feet, so 81+a=4a and 3a=81 making a=27 feet.
If the line that goes through (9, 6) is perpendicular to y = -1/3x + 7, then their slopes will be opposite reciprocals. The slope of the line given is -1/3. The opposite reciprocal of -1/3 is +3. If we have our new line passing through point with x coordinate 9 and y coordinate 6, we will use that x and y and the slope of 3 to solve the slope-intercept equation for b. Like this: 9 = 3(6) + b. 9 = 18 + b and b = -9. That means that the new equation, the one that is perpendicular to the given line, is y = 3x - 9.
To the right of the inaginar axis means the real part of a+bi is positive
below real axis means the inaginary part of a+bi is negative
a is real part
bi is imaginary part
so it should look like
a-bi
answer is B
The value of a, b and c can be calculated using the inverse function.
The calculated the value of a= 2, b=1 and c= -2.
Given:
The function is and its inverse is .
<h3>What is an inverse function?</h3>
- The inverse function of a function is defined if is a function that undoes the operation of .
- The inverse of exists if and only if is bijective, and if it exists, is denoted by .
Substitute the value of x= -1 in a given inverse function and calculate the value of a.
Substitute the value of x is 0 in given inverse function.
Substitute the value of x is 2 in given inverse function.
Therefore, the value of a= 2, b=1 and c=-2.
