The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer:
f(x) - when referring to a function - means that x is the input value that you substitute into an equation.
For example, if f(x) = 2x + 3 and you were asked to find f(2), you could substitute x = 2 into the equation 2x + 3 to get 7.
Hope this helps!
Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
Answer:
A c = -4 2/3
Step-by-step explanation:
5c +4 = 2(c-5)
Distribute
5c+4 = 2c - 10
Subtract 2c from each side
5c-2c+4 = 2x-2x-10
3c+4 = -10
Subtract 4 from each side
3c+4-4=-10-4
3c = -14
Divide each side by 3
3c/3 = -14/3
c = -14/3
Changing to a mixed numbers
c = -4 2/3
