We first need to write the function in standard form.

y = -x^2 - 7x + 18

To find the axis of symmetry, we do -b/2a

The a and b are the coefficients of the x values.

So a would be -1 since -x is same as -1x

Follow that, b would be -7.

Then just plug the values in. - (-7)/2(-1) = -7/2

The axis of symmetry is -7/2

Clint wants to keep a young tree from blow- ing over during a high wind. He decides that he should tie a rope around the tree at

Sergio039 [100]

Answer:

No, the 270 cm rope Clint has is not enough to do the job.

Explanation:

The height of tree where rope has to be tied = 180 cm

The distance of the stake from the base of the tree = 200 cm

We can say that the arrangement makes a right angle triangle, with the right angle situated at the base of the tree. The figure is attached below. Consult it for better understanding.

Length of the rope can be found by using Pythagoras theorem.

(Length of rope)² = 180² + 200²

Length of rope = 269 cm

As it is stated the additional 30cm of rope is required for tying from both ends. Total length of rope required is:

Total length of rope = 269 + 30

Total length of rope = 299 cm

As length of rope required is 299cm, the 270 cm rope Clint has is not enough to do the job.

The benefits of thinning a forest over other methods of forestry management

galben [10]

Answer:

III. The understory growth and remaining trees are healthier.

Explanation:

Forestry can be defined as the art and science of creating, development, management, conservation and analysis of the living organisms such as plants, trees and woodlands existing in the forest. This is usually done so as to tap into the environmental benefits associated with the forests and to ensure the continuous existence of wildlife, plant growth and development.

Forest Management is a branch of forestry. The field of forest management typically deals with legal, administrative, financial, economical, technical and social aspects of a forest so as to facilitate the smooth running and operation of the forest reserve.

Thinning is a forest management process which typically involves removing full rows of trees so as to increase the space between them and to reduce competition among trees for resources such as moisture, nutrients and sunlight.

Hence, the benefits of thinning a forest over other methods of forestry management include the understory growth and remaining trees are healthier.
