The standard form of the equation of a parabola is x = y2 + 10y + 22. what is the vertex form of the equation?

The vertex form of the parabola is  

C is the correct option.

Step-by-step explanation:

The standard form of the parabola is

We can write this equation in vertex form by using the completing square method.

For the expression , the value of b is 10.

Hence, add and subtract to the right side of the equation.

Thus, the equation becomes

Now, the expression

Hence, we have

We can simplify further as

Hence, the vertex form of the parabola is  

C is the correct option.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
