Answer:
Step-by-step explanation:
To find the slope between any two points, we can use the following slope formula:
Let (-7, -1) be (x₁, y₁) and let (3, 8) be (x₂, y₂). Substitute them into the slope formula:
Evaluate:
Therefore, the slope between the two points is 9/10.
The given equation of parabola is
Which can also be written as
Here vertex (h,k) is (1,2)
And value of a is
Formula of focus is
Substituting the values of h,k and a, we will get
Therefore the correct option is the last option .
The price of a painting in the year 2022 will be $ 568,000.
<h3>What is inflation?</h3>A rise in the amount of a certain product or service is known as inflation.
Given data;
Cost of painting in the year 2021, P₁ = $560,000
Cost of painting in the year 2022, P₂ =?
The amount increases every year,x = $8,000
The cost of painting in the year 2022 is found as;
P₂ = P₁ + x
P₂= $560,000 + $8,000
P₂ = $ 568,000
Hence the price of a painting in the year 2022 will be $ 568,000.
