The leading coefficient will always be the number multiplied to the highest degree variable.

Our highest degree term is 2x. Our leading coefficient would then be 2.

Answer:

It’s actually choice 4) -0.04

Step-by-step explanation:

You can see that as the years increase (when getting older), the size of the pupil decreases. So with that information, you can already eliminate choice 1 and 2 because they both show the rate of change increasing (which is wrong) and choice 3 and 4 shows the rate of change decreasing (which is right). To solve and find the right number, you can take any two numbers, subtract them, and divide them by 10. They reason why you do this because to want to find the difference in 10 years, and you divide it by 10 because the question wants us to find it per year (1 year).

Steps:

You can take 4.3 and 4.7, subtract to get -0.4, and divide it by 10 to get -0.04

You can also take 3.1 and 3.5, subtract to get -0.4, and divide it by 10 to get -0.04

Answer: -0.04

The diagonals of the rhombus bisect each other at right angle. The expression in terms of [tex]n[/tex] can be used to represent AD in rhombus ABCD is,

[tex]AD=\dfrac{1}{2} \sqrt{(2n+5) ^2+(4n-3) ]^2\\}[/tex]

The diagonals of the rhombus bisect each other at right angle.

Given information-

The length of the one diagonal of the rhombus is,

[tex]AC=(2n+5)[/tex]

The length of the another diagonal of the rhombus is,

[tex]BD=(4n-3)[/tex]

Let the center point of the rhombus is O as shown in the figure.

In [tex]\Delta AOD[/tex] the [tex]\angle AOD[/tex] is the right angle triangle. Thus by the Pythagoras theorem,

[tex]AD^2=AO^2+DO^2[/tex]

Suppose the above equation as equation number 1.

As the diagonals of the rhombus bisect each other thus,

[tex]AO=\dfrac{1}{2} AC\\DO=\dfrac{1}{2} BD[/tex]

Put the values in equation 1,

[tex]AD^2=(\dfrac{1}{2}AC) ^2+(\dfrac{1}{2}BD) ^2[/tex]

Put the values,

[tex]AD^2=[\dfrac{1}{2}(2n+5)] ^2+[\dfrac{1}{2}(4n-3) ]^2\\AD^2=\dfrac{1}{4}[(2n+5) ^2+(4n-3) ]^2\\AD=\sqrt{\dfrac{1}{4}[(2n+5) ^2+(4n-3) ]^2}\\AD=\dfrac{1}{2} \sqrt{(2n+5) ^2+(4n-3) ]^2\\}[/tex]

Hence the expression in terms of [tex]n[/tex] can be used to represent AD in rhombus ABCD is,

[tex]AD=\dfrac{1}{2} \sqrt{(2n+5) ^2+(4n-3) ]^2\\}[/tex]

Answer:

Step-by-step explanation:

Answer:

(6-1) = 5 Because Obio 6 minus 1 equals 5

Answer:

(i) 1/2x + 1/3y = 2 (ii) 2/x^0.5 + 3/y^0.5 = 2

1/3x + 1/2y = 13/6 4/x^0.5 - 9/y^0.5 = -1

(iii) 4/x + 3y = 14 (iv) 5/(x-1) + 1/(y-2) = 2

3/x - 4y = 23 6/(x-1) - 3/(y-2) = 1

(v) (7x-2y) / xy = 5 (vi) 6x+3y=6xy

(8x+7y) / xy = 15 2x+4y=5xy

(vii) 10/(x+y) + 2/(x-y) = 4 (viii) 1/(3x+y) + 1/(3x-y) = 3/4

15/(x+y) - 5/(x-y) = -2 1/[2(3x+y)] - 1/[2(3x-y)] = -1/8

Answer:

Step-by-step explanation:

Supplementary angles are two or more angles whose the addition of their measures add up to [tex]180^{o}[/tex].

Given: <1 and <2.

<1 + <2 =  [tex]180^{o}[/tex] (supplementary angles)

If <1 ≅ <2 (congruent property), then we have;

<1 + <1 =  [tex]180^{o}[/tex]

2<1 =  [tex]180^{o}[/tex]

<1 = [tex]\frac{180}{2}[/tex]

   = [tex]90^{o}[/tex]

<1 = [tex]90^{o}[/tex]

So that since <1 and <2 are congruent, then;

<1 ≅ <2 ≅ [tex]90^{o}[/tex]

Therefore if <1 and <2 are supplementary and congruent, then they are right angles.
