To use the tree house as the start of the zip line, the cable needs to be attached to the starting tree at a height of 16 feet above the graund. To meet the slope constraints, Vince wants to change the height 7 feet's and end the zip line at a height of 9 feet above the ground. He claims the vertical change meets the slope constraint. Test Vince's claim for tree A and tree B. Use specific numbers from the situations to justify nor refute whether having a vertical change of 7 feet will satisfy the slope constraint for each tree.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
