Answer:
7,8,9
Step-by-step explanation:
You just need the other ones together to be greater than 13
Example: 7+7=14, it is greater.
Answer:
Circumference=16pi
Arc Length=8pi
Step-by-step explanation:
Circumference formula=2(pi)(r), or d(pi)
The arc is only half of that in this case, therefore you would only pi(r) or 1/2(d)(pi).
Answer:
Equation of axis of symmetry is x = 2
Step-by-step explanation:
The equation of the parabola is given as;
y = -2x² + 8x - 7
The equation of the axis of symmetry is given by;
x = -b/2a
In the parabola equation given and using letters of quadratic equation, we can say that;
a = - 2
b = 8.
c = -7
Thus;
x = -b/2a = -8/(2 × - 2)
x = 8/4
x = 2
Equation of axis of symmetry is x = 2
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
