Thus, the two root of the given quadratic equation is 2 and -3 .
Step-by-step explanation:
Consider, the given Quadratic equation,
This can be written as ,
We have to solve using quadratic formula,
For a given quadratic equation we can find roots using,
...........(1)
Where, is the discriminant.
Here, a = 1 , b = 1 , c = -6
Substitute in (1) , we get,
and
and
and
Thus, the two root of the given quadratic equation is 2 and -3 .
Answer:
The tree is 17.5 ft tall
Step-by-step explanation:
We can use proportions to solve this.
Notice that Emily (5 feet tall) and her shadow (8 feet long) constitute the two legs of a right angle triangle (see attached image).
The nearby tree (unknown height H), will also cast a shadow (28 ft long) with the same inclination as Emily does due to the unique position of the sun relative to them.
Then we can use the proportion associated with the sides of similar triangles:
Then, we can solve for H in the equation:
