Answer:
25 meters below the edge; 6.25 seconds
Step-by-step explanation:
We can represent this with a linear function in slope-intercept form.
We know the rate of change is 4, since he climbs up at 4 meters per second. We do not know the value of b, the y-intercept.
This gives us
y = 4x + b
We know that he is 13 meters below the edge after 3 seconds. Using -13 for y and 3 for x,
-13 = 4(3) + b
-13 = 12 + b
Subtract 12 from each side:
-13-12 = 12+b-12
-25 = b
This gives us the equation
y = 4x - 25
He started out 25 meters below the edge of the volcano.
To find how long it took him to reach the edge, substitute 0 in for y:
0 = 4x - 25
Add 25 to each side:
0+25 = 4x-25+25
25 = 4x
Divide both sides by 4:
25/4 = 4x/4
6.25 = x
It takes him 6.25 seconds to reach the edge.
Answer:
$4.5
Step-by-step explanation:
The previous balance method is a method in which the creditor charges the interests according to the balance the consumer had at the beginning of the billing cycle and the operations that you do during the cycle don't affect your finance charges. Because of that, to find the aswer you have to calculate your finance charges using the previous balance that was $300:
Monthly interest: 18/12=1.5%
Previous balance: $300
$300*1.5%= $4.5
According to this, the finance charges would be $4.5 if the creditor uses the previous balance method.
Answer:
5, 2 1/2, -2/3, -1, -6, -20
The answer is 105 students.
A=50000(1.025^t), B=50000+3000t
A(10)=$64004.23, B(10)=$80000
So Brock will be earning $15995.77 more than Adam in the tenth year.
