Answer:

4. 480.38m² 6. 3.35

Step-by-step explanation:

Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.

From there. for no. 4:

You subtract 87 from 360 to find the angle of the major arc.

360-87=273

From there you must also know the formula to find the area of a sector which is:

(x/360)×pi×r²

In our case 273 is x and 14.2 is r so

(273/360)×pi×14.2²= 480.38

Do the same steps to find 6

Answer: norm of reaction

Step-by-step explanation:

norm of a reaction which is the capacity of a genotype to produce different phenotypes in response to the environment. The group of phenotypic expressions under different environmental conditions. A organism can own all the genetic complements necessary to fully development. However, if there is no suitable nutricion, the development does not occur. The environment only changes the phenotypic characteristics within certain limits ruled by the genotype (norm of reaction). The genotype do not determine a phenotypes, but a amount of possible phenotypes, a norm of reaction. A certain phenotype will  materialize itself depending on the interaction of a certain genotype with the environment.

Answer:

Not a right triangle

Step-by-step explanation:

We can figure out if it is a right triangle or not by using the pythagorean theorem.

a^2 + b^2 = c^2

In this case a and b are 16 and 18

In order for it to be a right triangle, c has to equal 34, in this problem.

16^2 + 18^2 = c^2

= 580^2

= \sqrt{580} = 24.0832

Since 24.0832 does not equal 34, this is not a right triangle

SoIve the system of equations by elimination. (Addition)<br> 1)-2x + 4y = -22<br> 2x + 8y = –26
Rufina [12.5K]

Answee:

We have these two equations:

-2x +4y =-22

2x + 8y -26

We need to try to get the same number multiplying both x or y, I think we can make the 2 of the first equation negative, for that, we multiply all the equation by -1:

2x + 8y =-26  ---- -2x - 8y =26

Now we have this:

-2x +4y = -22

-2x -8y = 26

Now e substract both equations:

-2x - (-2x) +4y -(-8y) = -22-26

12y = -48

Y = -48/12 = -4

And we replace to get x

-2x + 4y = -22

-2x +4*(-4)=-22

-2x - 16 = -22

x= -6/-2 =3
