Answer:
Step-by-step explanation:
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
Answer:
x₁ > x₂
Step-by-step explanation:
Both actions imply a parable trajectories, since both are projectile shot cases.
Let´s call x₁ maximum distance in the first case
The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.
In the second case, the parable curve is modeled by:
y = x₂*( 0.08 - 0.002x₂) or y = 0.08*x₂ - 0.002*x₂²
A second degree equation, solving for x₂ and dismissing the value x₂ = 0
we get:
y = 0 ⇒ x₂*( 0.08 - 0.002x₂) = 0 x₂ = 0
And 0,08 - 0.002*x₂ = 0
- 0.002*x₂ = - 0.08
x₂ = 0.08/0.002
x₂ = 40 f
Then x₁ > x₂
Answer:
A. The answer is 7.4x10^3
Answer:
£b = £1.68
A = £44.68
Step-by-step explanation:
Given:
A = 5 + 1.9m + b
Where,
A = total cost
m = number of miles travelled
£b = charge for booking online
£5 = fixed charge
A. Harry
A = £29.48
m = 12 miles
£b = ?
A = 5 + 1.9m + b
29.48 = 5 + 1.9(12) + b
29.48 = 5 + 22.8 + b
29.48 = 27.8 + b
29.48 - 27.8 = b
b = 1.68
£b = £1.68
b) If Sue books online and travels 20 miles, what will be
A = 5 + 1.9m + b
= 5 + 1.9(20) + 1.68
= 5 + 38 + 1.68
= 44.68
A = £44.68
