Answer:
20
Step-by-step explanation:
if you divide 50 from 2.5 you get 20
then take 20x2.5 and you get 50.
Area of triangle = (1/2)*base*height
20.335 = (1/2)*base*8.3
2*20.335 = base*8.3
(2*20.335) / 8.3 = base Use your calculator.
4.9 = base
base = 4.9cm
Our parabola open downward and therefore a is negative.
Explanation:
As value of a changes from positive to negative or from negative to positive, the direction of opening changes. For negative values of a we got negative parabolas that open downward. As the original formula y = x^2 we see that x^2 will always be positive because when you square a number it always gives positive value. Therefore the direction for which it will open, depends on value of a.
Answer:
3.6 x 10^6
Step-by-step explanation:
(4 ×10^10)(9×10^-5)
= (4 x 9) x 10^(10 - 5)
= 36 x 10^5
= 3.6 x 10^6 <-------in scientific notation
