If you would like to know what is the constant for the quadratic equation 9 * y = 4 * x^2, you can calculate this using the following steps:
<span>9 * y = 4 * x^2 /9
</span>y = 4 * x^2 / 9
y = 4/9 * x^2
The correct result would be B. 4/9.
Answer:
2 y x
Step-by-step explanation:
By definition of average acceleration,
<em>a</em> (average) = (3.7 m/s - 14.3 m/s) / (2.0 s) = -5.3 m/s²
Difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
25=5^2
x^2-5^2=(x-5)(x+5)=0
set to zero
x-5=0
x=5
x+5=0
x=-5
x=5 or -5
A
