Let t be the time passed in years and y be the value of baseball card.
You know that
- when x=0, then y=2;
- when x=5, then y=25;
- when x=10, y=8.
The equation in standard form is
Substitute given data into the equation:

Solve the system of equations:


Then the parabola equation is

Step 1: Simplify both sides of the equation.
x−7=15+3x
x+−7=15+3x
x−7=3x+15
Step 2: Subtract 3x from both sides.
x−7−3x=3x+15−3x
−2x−7=15
Step 3: Add 7 to both sides.
−2x−7+7=15+7
−2x=22
Step 4: Divide both sides by -2.
−2x/−2=22/−2
x=−11

Answer:
Fv = 79.63 lb
The total upward force Fv is 79.63 lb
Step-by-step explanation:
We need to determine the total upward force, the y component of force;
Given;
Force F1 = 60.5 lb, 82.4° above horizontal
Force F2 = 37.2 lb, (82.4-50.5)° above horizontal
The vertical component of Force F1 and F2 is;
Fv = 60.5sin(82.4) + 37.2sin(82.4-50.5)
Fv = 79.63 lb
The total upward force Fv is 79.63 lb
