A country has a total biocapacity of 6.21 ha/person, a biocapacity of grazing land of 0.85 ha/person, and a biocapacity of fores
leonid [27]

Answer:

44.8 %  

Step-by-step explanation:

Let p = the number of people. Then

Total biocapacity     = 6.21p  ha

Grazing biocapacity = 0.85p ha

Forest biocapacity    = <u>2.53p      </u>

Grazing + forest        = 2.78p ha

\text{Percent grazing + forest} = \dfrac{\text{grazing + forest}}{\text{Total}} \times 100 \, \% \\\\= \dfrac{\text{2.78p ha}}{\text{6.21p ha}} \times 100 \, \% = \mathbf{44.8 \,\%}

Write the equation of the parabola in vertex form. <br> vertex (2,1) point (3,-3)
Mariana [72]

first off let's notice that hmmm the vertex is above the point (3,-3), so if we "assume" is a vertical parabola, then it'd be opening downwards.... anyhow that said, let's plug in those values.

\bf ~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}

\bf vertex~~(\stackrel{h}{2}~~,~~\stackrel{k}{1})\qquad \implies \qquad y = a(x-2)^2+1 \\\\\\ \stackrel{\textit{we also know that }}{(3~~,~~-3)} \begin{cases} x = 3\\ y = -3 \end{cases}\qquad \implies -3=a(3-2)^2+1 \\\\\\ -3=a(1)^2+1\implies -3=a+1\implies -4=a \\\\[-0.35em] ~\dotfill\\\\ ~\hfill y = -4(x-2)^2+1~\hfill

Set up an equation that can be used to solve the variable.
sleet_krkn [62]

So sin in math means:

In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.

Con in math means:

In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.

in this case it has to be a sin. So its either A, or B.

NEED HELP!!!
lana [24]

Answer:

We will choose option D.

Step-by-step explanation:

In the given diagram the shown right triangle has Base = 3 units, Perpendicular = 4 and the Hypotenuse = 5 units,

Now, in option A.

The vertices of the triangle are (-3,-3), (-3,4) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 7 units, and 7√2 units.

So, it is not similar to the graphed triangle.

{Since, the ratio of corresponding sides of the similar triangles are the same}

Now, in option B.

The vertices of the triangle are (-3,-3), (-3,5) and (4,-3).

Hence, the side lengths of the triangle are 7 units, 8 units, and 10.63 units.

So, it is not similar to the graphed triangle.

Now, in option C.

The vertices of the triangle are (-3,-3), (-3,4) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 7 units, and 9.21 units.

So, it is not similar to the graphed triangle.

Now, in option D.

The vertices of the triangle are (-3,-3), (-3,5) and (3,-3).

Hence, the side lengths of the triangle are 6 units, 8 units, and 10 units.

So, it is similar to the graphed triangle.  

This is because the ratio of the corresponding sides of the given triangle and the graphed triangle are same and it is 2.(Answer)
