C = - 1/2t + 6
The equation usually looks like this
C = k*t + n
If t = 0 than
C = n (from the table we see that C is 6 if t = 0) than
N = 6 too
For t = 2 and c = 5 we have the equation
5 = 2k + 6
2k = -1
K = -1/2
Answer:
72f+40
Step-by-step explanation:
Y = ax² + bx + c is the equation of a parabola:
y = 4x² -8x -6 is our equation.
The axis of symmetry in a parabola is x = -b/2a
x = -(-8)/(2.4) = - 8/8 and x = - 1 (axis of symmetry
Given:
Alexis has a rectangular backyard that is 50 yards by 55 yards.
She wants to build a fence that stretches diagonally from one corner to the opposite corner.
To find:
The length of the fencing she needs.
Solution:
We have,
Length = 50 yards
Width = 55 yards
We know that, the diagonal of a rectangle is




On further simplification, we get


Therefore, the length of the required fencing is 74.3 yards.
