Answer:
2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Step-by-step explanation:
b = 640
r = 5.3% = 0.053
t = 25
y = 640 ( 1 + 0.053)^25
y = 640 ( 1.053)^25
y = 2327.49 ---> 25 hrs
starting plot points (0,640) and ending (25, 2327.49)
Answer:
a.
b.
Step-by-step explanation:
Given
<em>Direct Variation</em>
D = 264 cm when T = 11 s
Calculating (a)
First, the constant of variation (k) as to be calculated;
Since, there exist a direct proportion; then,
Make k the subject of formula
<em>D = 264 cm when T = 11 s; So</em>
<em /><em />
<em /><em />
So: Solving for (a)
Substitute 408 for D and 24 for k in
Divide both sides by 24
<em>Hence, time to move a distance of 408cm is 17s</em>
Calculating (b)
Substitute 3 for T and 24 for k in
<em>Hence, distance covered in 3 seconds is 72cm</em>
