A false hypothesis helps to understand what factors are not related to a certain outcome. This helps center experiments around hypotheses that are more relevant.
Answer:
The translation would be just a change in where the vertex would be.
The change in x value would be that it would go to the left 6. The change in y would be that in would go down 9.
Step-by-step explanation:
To find this use the vertex form base to determine the vertex of either equation. Using this equation, the vertex is always (h, k)
y = a(x - h)^2 + k
y = (x - 5)^2 + 7
VERTEX (5, 7)
y = a(x - h)^2 + k
y = (x + 1)^2 - 2
VERTEX (-1, -2)
Knowing these two, we can see that the x value goes back by 6 and the y value goes down by 9
Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
