Answer:
6/35
Step-by-step explanation:
I just used my calculator...
The point slip form would be: y+8=16(x-8). Not sure if that’s what you were looking for.
X+X+2+X+4 = 3X + 6 = 126
3X = 126-6 = 120
X = 120/3 = 40
X = 40
X+2 = 42
X+4 = 44
Assuming the function is
f(x) = x^4 + 3x^3-28x^2
Factorising, we get
f(x) = x^2(x+7)(x-4)
Therefore, there is a double root at x = 0 and singular roots at x = -7 and 4
double roots tend to bounce, kind of like the standard quadratic y = x^2
singular roots tend to cross, kind of like a straight line on a graph, y = mx + b
Therefore, it bounces at x = 0, and crosses at x = -7 and 4
In general, a root raised to an even power bounces, and a root raised to an odd power crosses.
The variation equation when y varies directly as the square of x is y = kx².
The value of y when x = 30 is 900k.
<h3 /><h3>Definition and types of variation:</h3>
Variation establish relationship between variable. Types of variation includes
- Direct variation
- Inverse variation
- Joint variation
- Combined variation
y varies directly as the square of x , Therefore,
where
k = constant of proportionality
Solve for y when x = 30.
Therefore,
y = kx²
y = 30²k
y = 900k
