What are the coordinates of the vertex of the graph? is it a maximum or minimum?

Vertex ( 0,1) and it is maximum.

Step-by-step explanation:

Given  : graph of parabola .

To find : What are the coordinates of the vertex of the graph? Is it a maximum or minimum.

Solution : We have given the graph of parabola

Vertex : the highest point ; the top.

Vertex : ( 0 , 1) because it cut at y ,

When the parabola opens down, the vertex is the highest point on the graph is called the maximum, or max.

Therefore, Vertex ( 0,1) and it is maximum.

nope

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
