The height of the ball after 1.5 seconds is 15.5 meters so option (C) will be correct.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the function as the height of ball f(x) and time x

f(x) = -10x² + 20x + 8

At x = 1.5

f(1.5) = -10(1.5)² + 20(1.5) + 8

f(1.5) = 15.5

Hence "The height of the ball after 1.5 seconds is 15.5 meters".

The distance AD is 49 miles.

As per the given values of speed and time, we will calculate the distance AC. Firstly equalising the units.

As per the known fact, 60 minutes = 1 hour

30 minutes = (1/60)×30

30 minutes = 0.5 hour

Now, speed, distance and time are related as -

Speed = distance ÷ time

Distance = speed × time

Distance = 62 × 0.5

Distance = 31 miles

So, AC = 31 miles and BC = 25 miles.

Therefore, AB = AC - BC

AB = 31 - 25

AB = 6 miles

The distance AD = AC + CD

AD = 31 + 3 × AB

AD = 31 + 3 × 6

AD = 31 + 18

AD = 49 miles

Therefore, the distance between AD is 49 miles.

The possible dimensions of the rectangle having a perimeter 10 are

1)length= 4 and bredth= 1

2)length= 3 and bredth= 2

The perimeter of rectangle=2( length of rectangle + breadth of rectangle)

Given that the perimeter of rectangle=10

10=2( length of rectangle + breadth of rectangle)

5=length of rectangle + breadth of rectangle

For a rectangle, length must be always greater than the breadth

The possible values of length of rectangle= 4 and 3

As a result,the Breadth of the rectangle will be 1 if length =4

As a result,the Breadth of rectangle will be 3 if length =2

Therefore, The possible dimensions of the rectangle having a perimeter 10 are

It is found that Ken will have run 3 laps and Hamid will have run 4  around a track.

Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.  Prime factorization is when all those factors are prime numbers.Thus, prime factorization expresses an integer in terms of multiples of prime numbers.

Prime factorization is unique for each integer.

To determine the number of seconds that will have passed when they meet again.  We will use the LCM, or least common multiple, for this.

Thus the prime factorization of each number:

80 = 10(8)

10 = 5(2)

8 = 2(4)

4 = 2(2)

80 = 2(2)(2)(5)(2)

60 = 10(6)

10 = 5(2)

6 = 2(3)

60 = 2(2)(3)(5)

For the LCM,

2(2)(5)(2)(2)(3) = 240

This means every 240 sec; they will both be at the start line.

Since Ken completes a lap in 80 seconds, then he will completes

240/80 = 3 laps in 240 seconds.

Since Hamid completes a lap in 60 seconds, then he will completes 240/60 = 4 laps in 240 seconds.

Hence, It is found that Ken will have run 3 laps and Hamid will have run 4.

Scientific notation:

Scientific notation is a method of presenting very large or very small numbers in a more simplified format. We know that whole numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers found after the decimal point needed to be represented in a more straightforward manner.

(1.8x10⁹) (6.7 x 10¹²) = 120.6×[tex]10^{20}[/tex]

Given (1.8x10⁹) (6.7 x 10¹²) =a x [tex]10^{b}[/tex]

The telephone pole is 35ft tall .

The height of any object is define as the distance measurement of that object from the top to its base. In geometry it is also called as altitude.

Height can be measured in various quantities such as feet, inches, centimeters etc.

Some of measurements are as below.

          1 feet = 12 inches

          1 feet = 30.48 cm

          1 inch = 2.54 cm

          1 feet = 3.28 feet

In the given question,

Convert 60 inches to feet ,

60 inches = 60/12 feet = 5 feet

Given, pole shadow = 50ft

child height =3.5ft

now, Set up  proportion between the ratios of the child and his shadow and the telephone pole and its shadow.

[tex]\frac{child \ height}{child \ shadow \ length} =\frac{pole \ height}{pole \ shadow \ length}[/tex]

Let, x be pole height

=> [tex]\frac{3.5}{5} =\frac{x}{50}[/tex]
