Answer:
Think of it as the perimeter of the circle
Answer:
Since it's increasing add 3.5% to 100%
= 103.5% of £16470.45
= 103.5/100 × 16470.45
= 17046.92
= £17046.92
Hope this helps.
Answer:
100
Step-by-step explanation:
10 x 10 = 100
The domain of the function would be -5
Th answer is would be D
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
