Step-by-step explanation:---------------
Answer:
37.8metres
Step-by-step explanation:
The arc of the arrow can be modeled by the equation:
y=-0.02x²+0.65x+4
Where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow.
The arrow hits the ground when its height (y) is zero.
Therefore, we determine the value(s) of x for which:
y=-0.02x²+0.65x+4=0
Using a calculator to solve the quadratic equation:
x=37.79 or -5.29
Since the distance cannot be a negative value, we ignore -5.29.
The distance from Linda when the arrow hits the ground is 37.8metres (to the nearest tenth)
2|3x + 5| = -10 . Divide both sides by 2:
|3x + 5| = -5 ===>3x+5=-5 & -3x-5=-5 In both cases x=0
The first one -8-13-18

Answer: 
Step-by-step explanation:
Given
Perimeter of the rhombus is 
Length of one of the diagonal is 
All the sides of the rhombus are equal
Area of the rhombus with side and one diagonal is
Insert the values
Area with two diagonals length can be given by
Thus, the area of the rhombus is 
and the length of the other diagonal is
