Answer:
Step-by-step explanation:
Only one of them has a < b in ax² + by² = c formula, making its graph horizontal
All the rest are vertical, see attached
B bsbdhdbhhdjddjdjdndhdhdhdgdggdhdhdhdhdhdhdhdhdhdhd
3 √10
I think since a^2+b^2=c^2
Answer:
h = 1.403733341286
Step-by-step explanation:
17.
the triangle of sides ‘l’ and ‘l-h’ is a right angled triangle.
Then

Then

Then

18.
For l = 6 and θ = 40 :

= 6-6cos(40)
= 1.403733341286
What do you mean, "solve"?
y = -4(x-2)² + 4
the line is a parabol with a maximum (2;4)
it's roots are -4(x-2)² + 4 = 0 => (x-2)² = 1 => x-2 = 1 => x = 3
=> x-2 = -1 => x = 1
symetrical axe: x = 2
is that all you need?
