17) What Is The Difference Between A Keystone And An Indicator Species And Why Are They Impofor Scientists

Answers

Answer 1

Answer:

See explanation

Explanation:

A keystone species is a species important to the environment such that when eradicated, much of its surrounding ecosystem will take a long time to recover from the drastic changes.  For example, sea otters are a keystone species of the kelp forests in the east part of the Pacific Ocean.  When they were almost hunted to extinction for the fur trade, the ecosystem suffered kelp loss as a result of overpopulation of sea urchins, which eat kelp.

An indicator species is a species that helps scientists measure the overall health of its ecosystem.  For example, scientists have used wood stork populations in the Everglades to measure the health of it, determining whether the habitat is suitable for many other species of wading birds.

Write a quadratic equation in standard form with the given roots. 3/2, 1/4

Answers

Answer:

The quadratic equation in standard form is  [tex]y= x^{2}-\frac{7}{4}\cdot x +\frac{3}{8}[/tex].

Explanation:

From Algebra, we remember that the order of the polynomial indicates the number of roots contained within. The factorized form of a second order polynomial (quadratic equation) is now introduced:

[tex]y = (x-r_{1})\cdot (x-r_{2})[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]r_{1}[/tex], [tex]r_{2}[/tex] - Roots of the polynomial.

And the standard form of the quadratic equation:

[tex]y = a\cdot x^{2}+b\cdot x +c[/tex] (2)

Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are the coefficients of the polynomial.

Lastly, we proceed to perform algebraic operations until standard form is found:

1) [tex]r_{1} = \frac{3}{2}[/tex], [tex]r_{2} = \frac{1}{4}[/tex] Given

2) [tex]y = \left(x-\frac{3}{2}\right)\cdot \left(x-\frac{1}{4} \right)[/tex] By 1)/Definition of factorized form

3) [tex]y = \left[x+\left(-\frac{3}{2} \right)\right]\cdot \left[x+\left(-\frac{1}{4} \right)\right][/tex] Definition of subtraction

4) [tex]y = \left[x+\left(-\frac{3}{2} \right)\right]\cdot x +\left[x+\left(-\frac{3}{2} \right)\right]\cdot \left(-\frac{1}{4} \right)[/tex] Distributive property

5) [tex]y = x\cdot x +\left(-\frac{3}{2} \right)\cdot x +\left(-\frac{1}{4}\right)\cdot x +\left(-\frac{3}{2}\right)\cdot \left(-\frac{1}{4} \right)[/tex] Distributive and commutative properties

6) [tex]y = x^{2} + \left[-\left(\frac{3}{2}+\frac{1}{4}\right)\right]\cdot x +\left(-\frac{3}{2} \right)\cdot \left(-\frac{1}{4} \right)[/tex] Distributive and associative properties/[tex](-1)\cdot a = -a[/tex]

7) [tex]y = x^{2}+\left(-\frac{7}{4} \right)\cdot x + \frac{3}{8}[/tex]  [tex]\frac{a}{b}\times \frac{c}{d} = \frac{a\cdot c}{b\cdot d}[/tex]/[tex](-a)\cdot (-b) = a\cdot b[/tex]

What is a Parallelogram?

It is a polygon with four sides. The total interior angle is 360 degrees. A Parallelogram's opposite sides are parallel and equal. Its diagonals intersect in the center.

If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6. The equation is given as,

BD = 2BE

5x - 3 = 2(2x + 2)

5x - 3 = 4x + 4

x = 9

Then the value of the line segment AE is given as,

AE = 4(9) - 6

AE = 36 - 6

AE = 30 units

Then the value of the line segment AC is given as,

AC = 2AE

AC = 2(30)

AC = 60 units

The value of the variable 'x' is 9 units. Then the length of the line segment will be 60 units.
