Answer:
C
Step-by-step explanation:
Exponential decay should be in this format A = Ao × e^(-kt)
Answer:
y = 3 (4)^x
Step-by-step explanation:
quadruples means multiplies by 4
This equation is in the form
y = ab^x where a is the initial amount and b is the amount we multiply by
y = 3 (4)^x
Answer:
6x-y = -18
Step-by-step explanation:
Answer:
Step-by-step explanation:
Give the data
198 sq.yd × 8 sq ft ×7
Note that we have two unit of measurement which are yd and ft and 7 is just a constant
So we need to convert them,
Then, 1 yd = 3ft
Also notice that they are square.
Then square both sides of the comparison
(1 yd)² = (3 ft)²
1 sq.yd = 9 sq.ft
Then, back to our question,
198 sq.yd × 8 sq ft ×7
Let covert to ft
198 sq.yd× (9 sq.ft/1 sq.yd) ×8 sq.ft×7
sq.yd cancels out
99,792 sq.ft × sq.ft
99,792 ft⁴
Let convert to yd
198 sq.yd × 8 sq ft ×7
198 sq.yd×8 sq.ft (1 sq.yd / 9sq.ft )×7
1,232 sq.yd × sq.yd
1,232 yd⁴
Answer:
y = -1/3x -2
Step-by-step explanation:
Slope intercept form of a line is
y= mx+b
We need to solve for y
1/3x +y = -2
Subtract 1/3x from each side
1/3x -1/3x +y =-1/3x -2
y = -1/3x -2
