Let us Verify Option - B
If Option - B is the Solution it should satisfy the Equation.
Given Equation : 7x - 5y = 28
Substituting x = 4 and y = 0 in the Equation, We get :
⇒ 7(4) - 5(0) = 28
⇒ 28 = 28
⇒ Ordered pair (4 , 0) is the Solution of the Equation 7x - 5y = 28
⇒ Option B is the Answer
The height of the ball at ground level would be 0 feet.
Set h to 0 and solve for t:
Rewrite the equation as
-5t^2 -2t +49 = 0
Factor -1 out of the equation to get:
5t^2 + 2t -49 = 0
Use the quadratic formula:
-b +/- sqrt(b^2 -4(ac) / 2a
Where a = 5, b = 2 and c = -49
The quadratic formula becomes:
-2 +/-sqrt(2^2 – 4(5*-49) / (2*5)
Simplify to get :
T = -2 +/-sqrt246 / 10
T = 2.936 and – 3.336
Since the time has to be a positive value t = 2.936 seconds.
Rounded to the nearest hundredth = 2.94 seconds.
divide 23 by 3= 7 and 2/3
so ur answer will be 7 2/3
