<h2>Answer:</h2>

Collinear points are two or more points that lie on the same line.

<h2>Step-by-step explanation:</h2>

<u>Collinear Points--</u>

Two or more points are said to be collinear if they lie on the same line and if they don't lie on the same line then they are called non-collinear points.

( for example--

In a triangle all the three points do not lie in the same line.

Hence, they are non-collinear points)

( similarly we use the definition of coplanar.

Two or more points are said to be coplanar if they lie on the same plane)

Eva8 [605]

Answer:

The side lengths of the image after the dilation = 13.5 cm and 20.25cm

Step-by-step explanation:

A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.

Dilation can also be referred to as scale factor

6cm × 2.25 = 13.5 cm

9 cm × 2.25 = 20.25 cm

The side lengths of the image after the dilation = 13.5 cm and 20.25cm

The population of Kings County, New York, has increased 0.53% each year, over several years. The population in 2000 was 2,465,32
Deffense [45]

We have been given that population of Kings County, New York, has increased 0.53% each year, over several years. The population in 2000 was 2,465,326.    

Formula to find population growth: N=N_0(1+r)^{t}

Now we will find expected population of year 2015 by substituting t=15 in our given formula.  

2,465,326(1+0.0053)^{15}

2,465,326(1.0053)^{15}

2,465,326\cdot 1.0825182787557597

2668760.45809\approx 2668760

Therefore, expected population in year 2015 will be 2668760.

Solve the following equation for 0° ≤ θ &lt; 360°. Use the "^" key on the keyboard to indicate an exponent. For example, sin2x w
never [62]

<u>Answer-</u>

\boxed{\boxed{x=90^{\circ},270^{\circ}}}

<u>Solution-</u>

The given equation-

\Rightarrow 2\sin^2 x-\cos^2 x-2=0

As

\sin^2 x+\cos^2 x=1\ \ \Rightarrow \cos^2 x=1-\sin^2 x

Putting this,

\Rightarrow 2\sin^2 x-(1-\sin^2 x)-2=0

\Rightarrow 2\sin^2 x-1+\sin^2 x-2=0

\Rightarrow 3\sin^2 x-3=0

\Rightarrow 3\sin^2 x=3

\Rightarrow \sin^2 x=1

\Rightarrow \sin x=\sqrt1

\Rightarrow \sin x=\pm 1

\Rightarrow \sin x=1,\ \sin x=-1

\Rightarrow x=\sin^{-1}(1),\ x=\sin^{-1}(-1)

\Rightarrow x=90^{\circ}+n360^{\circ},\ x=270^{\circ}+n360^{\circ}

Where n=0, 1, 2, ......

As given 0° ≤ x < 360°, so putting n = 0

\Rightarrow x=90^{\circ},\ x=270^{\circ}

When an object falls freely, the formula for the distance it falls is d= 4.9t^2 where d is
german

Answer:

a) 122.5 m ; b) 10 s

Step-by-step explanation:

Just use the given equation and plug in what you know.

a)

d = 4.9t^2

d = 4.9(5^2)

d = 4.9 * 25

d = 122.5 m

b)

d = 4.9t^2

490 = 4.9t^2

100 = t^2

t = 10 s
