Answer:
t = -2.566s and -1.169s
Step-by-step explanation:
Given the height of the ball expressed at
h(t) = 5t²+14t+3
The ball will hit the ground at h(t) = 0
Substitute and get t
0 = 5t²+14t+3
Use general formula
t = -14+/- √14²-4(5)(3)/2(5)
t = -14+/- √196-60)/10
t = -14+/- √136/10
t =-14+/- 11.66/10
t = -25.66/10 and -2.338/2
t = -2.566s and -1.169s
Hence the ball will hit the ground at these times
Answer:
1.548 gallons
Step-by-step explanation:
Length of the rectangular wall = 25.1 ft.
Width of the rectangular wall = 18.5 ft.
Area of the rectangular wall = length * width = 25.1 * 18.5
= 464.35 square feet
300 square feet wall can be painted using 1 gallon of paint.
=> 1 square feet wall can be painted using gallon of paint.
=> 464.35 square feet wall can be painted using gallon of paint.
= 1.548 gallons of paint
The expression which represents Daria's total cost is; 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05
<h3>Percentage</h3>
- Amount paid for shoes = $x
- Tax = 5%
Total cost = x + (5% of x)
= x + (0.05 × x)
= x + (0.05x)
Total cost = 1.05x
Therefore, the correct answer is; 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05
