Step-by-step explanation:
Carly buys t play tickets at $14.50 per ticket and t choir concert tickets at $5.50 per ticket. What is the cost for play tickets and choir concert tickets.
The cost of the play tickets is the number of play tickets multiplied by the cost of each ticket.
Play tickets: number of tickets: t; cost of each ticket: $14.50
Cost of play tickets: 14.50t
The cost of the choir tickets is the number of choir tickets multiplied by the cost of each ticket.
Choir tickets: number of tickets: t; cost of each ticket: $5.50
Cost of choir tickets: 5.50t
Total cost of play tickets and choir tickets:
14.50t + 5.50t = 20t
Answer:
Step-by-step explanation:
- Total weight = 200 lb
- Rotted weight = 45 lb
<u>Rotted %</u>
Differentiate implicitly using the power rule:
<span>12x^2 + 15y^2y' = 0 </span>
<span>Make y' the subject: </span>
<span>15y^2y' = -12x^2 </span>
<span>y' = -(4x^2) / 3y^2 </span>
<span>Differentiate again using the quotient rule: </span>
<span>y'' = [-8x(3y^2) - 6yy'(-4x^2)] / 9y^4 </span>
<span>y'' = (-24xy^2 + 24x^2yy') / 9y^4 </span>
<span>Simplify: </span>
<span>y'' = (-8xy + 8x^2y') / 3y^3 </span>
<span>Substitute (4x^2) / 3y^2 back for y': </span>
<span>y'' = (-8xy + 8x^2 * 4x^2 / 3y^2) / 3y^3 </span>
<span>y'' = (-24xy^3 + 32x^4) / 9y^5</span>
