where 'a' cannot be zero.

Explanation:
The vertex is (h,k)
The x coordinate of the vertex is h which is found through this formula
For example, if we had the quadratic , then we'll plug in a = 3 and b = -6 to get:
------------
To find the value of k, we plug that h value into the original standard form of the quadratic and simplify.
It's interesting how we end up with the numerator of which is similar to found under the square root in the quadratic formula. There are other ways to express that formula above. We need to avoid dividing by zero. The values of b and c are allowed to be zero.
To find out how many gram the puppy increase each day,here's what we can do:
weight of day 4 - weight of day 2
=365 - 305
=60g
To comfirm,we can use another pair
weight of day 4 - weight of day 2
=485-425
=60g
From the above,we can see that the puppy increase 60 grams each two days,meaning that it would increase 60÷2=30 gram each day.
We can then find its weight of age of 5 days:
365+30
=395g
Thus the answer is D.395
Hope it helps!
Answer:
boxes

Answer:
A. 32.08
Step-by-step explanation:
The figure given is a right triangle. We would apply trigonometric ratios formula to find x.
Reference angle = 58°
Hypotenuse = x
Adjacent length = 17
Thus, we would apply the following:
Plug in the values
Multiply both sides by x
Divide both sides by Cos(58)
