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.
Answer:
GCF(15a; 28b²) = 1
Answer:
3/16 pounds more.
Step-by-step explanation:
It is 1 1/8 - 15/16
= 9/8 - 15/16
= 18/16 - 15/16
= 3/16.
The amount added to the original price of the jewelery is the Markup price. Hence, the amount added is $16.34
- Markup = 57% = 0.57
- Cost of jewellery = c
- Retail price = $45
Retail price = cost of jewellery + Markup
$45 = c + 0.57c
45 = 1.57c
<em>Divide both sides by 1.57</em>
c = 45/1.57
c = $28.66
The Markup price = (Retail price - Original price)
- Markup = $45 - $28.66 = $16.34
Therefore, the amount added to the original price is $16.34
