What is 4 over the quantity of 3 to the negative 2nd power?
1 answer:
If I've understood your question, you're asking about this:
A number raised to a negative power is the same as the inverse of that number raised to the positive power. Basically the number moves from the numerator to the denominator or the denominator to the numerator. So 1/(3^-2) is the same as 1 / (1/3^2), which is the same as 3^2. That means what you have here is 4 x 3^2, which is 36.

Answer:
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
substitute
apply distributive property
see the attached figure to better understand the problem
