Step-by-step explanation:
Answer:
616 square centimeters
Step-by-step explanation:
Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.
Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.
Multiply 14 squared by 22/7:
(22/7)(14^2)
This gives us (22/7)(196); (4312/7); 616.
Therefore, the area of the circle is approximately 616 square centimeters.
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2 + k, where (h, k) is the vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>
Answer:
x > 28/3
Step-by-step explanation:
34 > 3(2 − x)
simplify the bracket
34 > 6 -3x
combine the like terms
34 - 6 > 3x
28 > 3x
divide by 3
x > 28/3
Sorry I don't know how to graph here, but I can graph it by writing the way it can be graphed.
It is in slope intercept form; y = mx + b
where mx is the slope and b is the y-intercept;
x>28/3; where 28/3 is the slope which means; at the y-intercept, go up 28 times and to the right 3 times
And b is 0; which means at 0 where the slope will be applied, go up 28 times and to the right 3 times.
Hope this helps!
Good luck.
