Answer:

(a) [tex]y = 4.5x + 22[/tex] -- The equation

(b) 31 inches

Step-by-step explanation:

Given

See attachment

Solving (a): The equation of the trend line.

We start  by calculating the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where

[tex](x_1,y_1) = (0,22)[/tex]

[tex](x_2,y_2) = (4,40)[/tex]

So, we have:

[tex]m = \frac{40 - 22}{4 - 0}[/tex]

[tex]m = \frac{18}{4}[/tex]

[tex]m = 4.5[/tex]

The equation is then calculated using:

[tex]y = m(x-x_1)+y_1[/tex]

Where:

[tex](x_1,y_1) = (0,22)[/tex]

[tex]m = 4.5[/tex]

[tex]y = 4.5(x - 0) + 22[/tex]

Open bracket

[tex]y = 4.5x - 0 + 22[/tex]

[tex]y = 4.5x + 22[/tex]

(b) The height of a 2 year old.

To do this, we substitute 2 for x in [tex]y = 4.5x + 22[/tex]

[tex]y = 4.5 * 2 + 22[/tex]

[tex]y = 9+ 22[/tex]

[tex]y = 31[/tex]

The prediction is 31 inches

Answer:

1000

Step-by-step explanation:

The population of the suburb after each decade d is given by the equation as follows :

[tex]P=4000\times 2^d[/tex]

We need to evaluate the expression for d = -2.

Put d = -2 in the above equation. So,

[tex]P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000[/tex]

So, if d = -2, then the population of the suburb is equal to 1000.

From the given triangles RST and TXY, angle R is equal to angle XTY. Therefore, option B is the correct answer.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

Given that, ΔRST≅ΔTXY.

We know that, corresponding parts of congruent triangle are equal

Here, ∠R=∠XTY

Therefore, option B is the correct answer.

x=22

x=23

x=24

Step-by-step explanation:

We are given that

[tex]19<r[/tex]

[tex]r<25[/tex]

We have to find value of x which is a solution to both of the given inequalities.

First we find the solution of given inequalities

[tex]19<r<25[/tex]

The value of r lies between 19 and 25.

Therefore, the possible values of r are

20,21,22,23,24

Hence, the value of x which is the solution of both given inequalities is given by

x=20

x=21

x=22

x=23

Step-by-step explanation:

Given

Shape: Isosceles Triangle

[tex]Perimeter=24\ in[/tex]

[tex]Side = 4\ in[/tex]

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

[tex]x + x + 4 = 24[/tex]

[tex]2x + 4 = 24[/tex]

Collect Like Terms

[tex]2x = 24-4[/tex]

[tex]2x = 20[/tex]

Divide both sides by 2

[tex]\frac{2x}{2} = \frac{20}{2}[/tex]

[tex]x = \frac{20}{2}[/tex]

[tex]x = 10[/tex]

The other sides are 10in each
