Answer:
(6,-31)
Step-by-step explanation:
f(x) = (x-6)^2 -31
This is in the form
f(x) = (x-h)^2 +k
where (h,k) is the vertex
(6,-31) is the vertex of the parabola
Its a this is not hard you need to know this
Answer:
9. By every 10 seconds, the meters traveled increase by a constant of 8.5 meters.
10. (1,2), (2,4), (5,10), (8,16)
Step-by-step explanation:
For question 9, here is an example. You can find the constant of proportionality by dividing 85 by 10, which is 8.5. So every 10 seconds, the distance traveled in meters by the object will have multiplied by 8.5. You can also do 170 divided by 20, which is also 8.5 thus verifying our answer. Hope this helps you, sorry I couldn’t explain it better.
Answer:
• new garden area = 2x^2
• new side length = 8√2 ft
Step-by-step explanation:
We are given that the area of a square of side x is ...
A = x^2
We want to double that area, so we can multiply by 2:
2A = 2x^2
___
The original formula tells us that the side length x is the square root of the area:
√A = x . . . . . square root of original formula
Then the side length of the square with doubled area will be
new side length = √(new area) = √(2x^2) = x√2
For an original side length of 8 ft, the new side length will be ...
new side length = (8 ft)√2 = 8√2 ft.
