For this case it is observed that the "zeros" are to the left of the expression, therefore the exponent, to be expressed in scientific notation, will be negative. That is to say:
This means that by running the decimal 6 spaces to the left we will get the initial expression.

Answer:
∠ f = 33°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin f = =
, thus
∠ f = (
) = 33° ( to the nearest degree )
Answer:
This question is clearly incomplete, so i will answer it in a really general way.
Suppose that for a quadratic function, we know that the x-intercepts are a and b.
And we also know that this function passes through the point (c, d).
First a definition, for a n-degree polynomial with the x-intercepts {x₁, x₂, ...,xₙ} and a leading coefficient K, we can write this polynomial in the factorized form as:
p(x) = K*(x - x₁)*(x - x₂)*...*(x - xₙ)
Now let's do the same for our quadratic function, we can write it as:
f(x) = K*(x - a)*(x - b)
(where a and b are known numbers)
Now we also know that this function passes through the point (c, d)
This means that:
f(c) = d
then:
d = K*(c - a)*(c - b)
With this equation we can find the value of K,
K = d/( (c-a)*(c - b))
Then the quadratic function is:
Where again, it is supposed that you know the values of a and b, and also the point (c, d)
