B. D(x) = 0.002x3 + 0.99x2 + 4x - 13
C. D(x) = 0.002x3 - 1.01x2 + 4x - 13
D. D(x) = 0.002x3 - 0.99x2 - 4x + 13
(0.002·x^3 - 0.01·x^2) - (x^2 - 4·x + 13) = 0.002·x^3 - 1.01·x^2 + 4·x - 13
Answer: 9.8 percent
Step-by-step explanation:
It increased by 25 cents
25 out of 2.55 is .098 and turned to a percent is 9.8
Answer: 11
Step-by-step explanation:
2.30 ---- 100%
2.55 ----- x
x= 2.55* 100/2.30= 110.87
111-100 =11
Answer: He will need to assemble 12 bikes, because 12 x 15.50 = $186 and $186 + 150 = $336
Step-by-step explanation: Don't need one :)) it's basic math
building?
A man of mass of 80 kg standing at the top of a tall building has 96000 J of G.P.E. so, the height of the building would be 122 m.
The gravitational potential energy is defined as the product of mass, acceleration due to gravity, and height.
PE = mgh
Given PE = 96000 J and m = 80 kg
PE = mgh
96000 J = (80 kg) (9.8 m/s²) h
h = 96000 / (80 kg) (9.8 m/s²)
h ≈ 122 m
Thus, The height is 122 m approximately.

Step-by-step explanation:
Gravitational potential energy is:
PE = mgh
Given PE = 96000 J and m = 80 kg:
96000 J = (80 kg) (9.8 m/s²) h
h ≈ 122 m
Round as needed.
False in a triangle 2 sides are the same and one is different.
A triangle can be formed with side lengths 2 in, 3 in, and 6 in.
According to the question
A triangle can be formed with side lengths 2 in, 3 in, and 6 in.
For three line segments to be able to form any triangle you must be able to take any two sides, add their length and this sum be greater than the remaining side.
The sum of two smaller sides is
So, 5 inches < 6 inches
Hence, False in a triangle 2 sides are the same and one is different.
