Answer:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k). This makes sense, if you think about it.

step by step:

1. Get the equation in the form y = ax2 + bx + c.

2.Calculate -b / 2a. This is the x-coordinate of the vertex.

3.To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

Answer:

neither exponential nor linear

Step-by-step explanation:

A linear relationship will show a common difference between adjacent value. Here, the first differences between the first three values are 5 and 33. They are not the same, so the relation is not linear.

An exponential relationship will show first differences that are continuously increasing or decreasing by increasing or decreasing amounts (respectively).

As we showed, the difference between May 28 and May 27 is 33. This is more than the previous difference. However, the difference between May 30 and May 31 is only 28, which is less than a previous difference.

The relation is not exponential.

A graph points up the non-linearity of the relation.

A car can travel 476 miles on 14 gallons of gas.Write an equation relating the distance d to the number of gallons of gas does t

bazaltina [42]

Mpg = 476/14 = 34 mpg

d = 578 miles = (34 mpg)(x gallons)

578 = 34x

x = 578/34 = 17 gallons

Solve the following quadratic equations using factoring. C. X^2-10=9x

boyakko [2]

we can easily solve this one by splitting theiddle term

x2 - 9x -10

x2 -10x + x - 10

x(x - 10) 1( x - 10)

(x + 1) (x-10)

x = -1 or 10

Answer:

(x-1) is a factor of the polynomial.

Step-by-step explanation:

Given:

f(x) = x³ + 6x² + 3x - 10

It is required to find which option is a factor of the given polynomial.

Factor the term (-10):

-10 = 1 * -10

= -1 * 10

= 2 * -5

= -2 * 5

As the given options are: (x+1) , (x-1) , (x-2) , (x-10)

So, the possible roots are: -1 , 1 , 2 , 10

So,

we will Check the values -1 , 1 , 2 , 10 to find which of them will make f(x)= 0

If x = -1 ⇒ f(x) = (-1)³ + 6*(-1)² + 3*(-1) - 10 = -1 + 6 - 3 - 10 = -8

So, x = -1 is not one of the roots ⇒ (x-1) is not one of the factor.

If x = 1 ⇒ f(x) = 1³ + 6*1² + 3*1 - 10 = 1 + 6 + 3 - 10 = 0

So, x = 1 is one of the roots ⇒ (x-1) is one of the factor

The other values { 2 , 10} also are not the roots of the function

So, the answer is the second option

(x-1) is a factor of the polynomial.
