The inverse of this would be
Answer:
9.3 is 5.8125% of 160
Step-by-step explanation:
This equation of the circle is in a center-radius form which is more generally written as,
(x - h)² + (y - k)² = r²
From the equation, the center of the circle is (h,k) and r is the radius. From the given equation above, the center of the circle is (-2,5).
Answer:
area: 64
perimeter: 32
Step-by-step explanation:
8*8=64
8+8+8+8=32
Answer:
(3, - 9)
Step-by-step explanation:
Differentiate using the power rule
y = a
, then
= na
Given
y = x² - 6x
= 2x - 6
Equate to zero since the measure of gradient is
, that is
2x - 6 = 0 ( add 6 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into y for corresponding value of y
y = 3² - 6(3) = 9 - 18 = - 9, thus
(3, - 9 ) are the coordinates of the point where the gradient is zero
