I hope this helped. I factored everything down, wrote it a different way, and got this.
Hello :
calculate the slope :
<span>2x + 5y = 10
5y = -2x +10
y = (-2/5)x +2
the slope is (-2/5)... (</span><span> parallel so : same slope )
an equation is : y - (-5) = (-2/5)(x-1)</span>
Answer: 9 seconds
Step-by-step explanation:
When the object hit the ground,
Height h = 0
Therefore,
h(x)= -5(x+1)(x-9) = 0
0 = -5(x+1)(x-9)
Open the bracket
0 = (-5x - 5)( x - 9)
0 = -5x^2 + 45x - 5x + 45
0 = -5x^2 + 40x + 45
Divide all by -5
0 = x^2 - 8x - 9
Factorizing the equation gives
(x + 1)(x- 9)
x = -1 or 9
Since Time can't be negative
Therefore, the time seconds after launch the object will hit the ground is 9 seconds

The horizontal distance between the base of the ladder and the wall is 12.6 feet.
<h3>What is t
rigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let d represent the distance between the base of the ladder and the wall.
Using trig ratio:
cos(61) = d/26
d = 12.6 feet
The horizontal distance between the base of the ladder and the wall is 12.6 feet.
