7+7+1=15 hopefully it helps :)
Since we have to solve the given formula for h(height) so, the correct option is (a)
Answer:
8,297.741÷0.529=16876.63
to the nearest whole number it is 16877
Step-by-step explanation:
since 5-9 are rounded up
90:18
divide using 3 on both sides
90:18
30:6
10:2
now lets use 2
10:2
5:1
5:1 is the equal ratio to 90:18
Answer:
see explanation
Step-by-step explanation:
I will begin with part two, first.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius.
Given
x² - 18x + y² - 10y = - 6
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is
(x - 9)² + (y - 5)² = 100 ← in standard form
with centre = (9, 5 ) and r = = 10
