MODELING REAL LIFE You jump off a diving board
into a pool. You reach a maximum height of 25 feet
after traveling 1 foot horizontally, and hit the water
6 feet from the diving board. The path of your dive
can be modeled by a parabola, where y is the height
(in feet) and x is the horizontal distance traveled (in
feet). What is the height of the diving board?

The given statement is completely true.

This is because the definition of slant height is the altitude of the lateral face of a pyramid or cone which is true.

There are three dimensions of a cone.

The vertical height (or altitude) is the perpendicular distance from the top down to the base.

The radius of the circular base slant height is the distance from the top, down the side, to a point on the base circumference.

Given statement 'To find the length of the hypotenuse of a right triangle, take the square root of the difference of the squares of the legs.' is False.

In given question,

We have been given a statement 'To find the length of the hypotenuse of a right triangle, take the square root of the difference of the squares of the legs.'

We know that a hypotenuse is the largest side of a right triangle.

According to Pythagoras theorem,

in a right triangle c² = a² + b²

where c is the hypotenuse of a right triangle

a, b are perpendicular sides of the right triangle

This means, to find the length of the hypotenuse of a right triangle, take the square root of the sum of the squares of the legs.

Therefore, given statement 'To find the length of the hypotenuse of a right triangle, take the square root of the difference of the squares of the legs.' is False.

It takes the object about 26/49 minutes to travel 5 1/5 miles.

A mixed fraction is a non-integer that consists of a whole number and a proper fraction. An example of a mixed fraction is 1 1/2.

Speed measures how fast an object is moving with respect to time. Speed is the total distance travelled per time.

Speed = total distance / total time

In order to determine the total time it would take the object to travel the distance, divide the distance travelled by the speed.

Time = distance / speed

The simplification by combining like terms of b -2(1 + c - b) is 3b -2c - 2.

According to the given question.

We have an expression b -2(1 + c - b).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression b -2(1 + c - b).

Here b and 2b both are the like terms.

So, we add and subtract coeffcients of b to simplify the given expression.

Therefore, the simplification of the expression b -2( 1 + c - b) is given by

b - 2( 1+ c - b)

= b - 2 -2c + 2b

= 3b -2c - 2

Hence, the simplification by combining like terms of b -2(1 + c -b) is 3b -2c - 2.

We can use the formula for the sum of a geometric series as Summation.

What is Geometric Series:

A geometric series is the sum of finite or infinite terms of a geometric sequence. For the geometric sequence a, ar, ar2, ..., arn-1, ..., the corresponding geometric series is a + ar + ar2 + ..., arn-1 + .... We know that "series" means "sum". In particular, the geometric series means the sum of the terms that have a common ratio between every adjacent two of them. There can be two types of geometric series: finite and infinite.

Now, Solution of the given problem

We can write

0.999...=9/10+9/100+9/1000+⋯

=9/10+9/10(1/10)+9/10(1/10)2+⋯

=∞∑n=0 9/10(1/10)n,

which is a geometric series

with a=9/10and r=1/10

The fundamental geometric shapes are lines and angles. Infinite points that stretch infinity in both directions make up lines, which are geometric objects. Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines. A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints. The most useful area of mathematics is the study of geometric shapes and their characteristics. As we've already mentioned, the foundation of any geometric shape is made up of lines and angles. Without employing lines and angles, it is impossible to draw a two-dimensional to three-dimensional shape. Consequently, it is imperative to discover the meanings of the two terminologies. Here, the fundamental definitions and characteristics of lines as well as angles are provided. A line is a simple, one-dimensional shape that can go on forever in opposing directions. A line may be vertical or horizontal. It can be drawn either top to bottom or left to right. When the ends of two rays collide at a single location, an angle is a geometry that results. They are expressed as radians or degrees (°). A 360-degree angle is the same as a whole rotation.

Let the angle m2 be x

so, according to the question m1= 2m2=2x

The two towns will be 15 centimeters apart on the map.

Here, we are given that a map has a scale factor of 1:24 000.

This means that if the distance between two points on the map is say 1 meter then in reality, these two points will be 24,000 meters apart.

Now, we are given that two towns are 3.6 kilometers apart

That is in reality, they are 3.6 km away

Let them be x kilometers away on the map

The ratio of the distances on map and in real life must be equal to 1/24,000

⇒ x/3.6 = 1/24,000

x = 3.6/24,000

x = 0.00015 kilometers

or x = 15 centimeters

The distance between the coordinates is 2+√19.

According to the question, the given problem can be solved by using the standard distance formula.

Now, the coordinate values are:

p(a, 2a); q(4, 3) and Distance = 10 units

Therefore, from the given parameters we can write:

x1 = a; y1 = 2a; x2 = 4; y2 = 3

Now,

Distance^2 = (x1 - x2)^2 + (y1 - y2)^2

Substituting the given values, we get:

Distance^2 = (4 - a)^2 + (3 - 2a)^2 = 16 +a^2 - 8a + 9 +4a^2 - 12a

100 = 25 + 5a^2 - 20a

5a^2 - 20a - 75 = 0

a^2 - 4a - 15 = 0

a = 2+√19

Hence, the distance between the coordinates is 2+√19.

If a/b = c/d then a and d are the extremes.

Ratio is defined as the comparison of two quantities. The ratio between quantities a and b can be expressed as a : b or a/b.

On the other hand, proportion is defined as the equality between two or more ratios.

a : b = c : d

Two ratios are equivalent if their cross-products are equal. Cross products are the products of the extremes and means. The 1st and and 4th terms of a proportion is called the extremes, while the 2nd and 3rd is the means of a proportion.

1 unit left,2 units down and 90° clockwise rotation is the transformation of figure Q to make figure R.

Transformation is rearranging a graph by a given rule it could be either increment,decrement, reflection, or rotation.

Reflection is a mirror image of a graph about any axis.

It seems that figure R is the rotation of Q clockwise by 90°.

In figure Q,

The Coordinate of the bottom left point of it is (3,1) if we rotate by 90° then it will remain at (3,1).

The coordinate of the same point in figure R is (2,-1)

So,

3 + x = 2 → x = -1 (1 unit left)

1 + y = -1 → y = -2 (2 units down)

Using the values of the first term and the sum of the first 40 terms of the given series, a(40) = 300

Suppose we are given a series:

  a(1) + a(2) + a(3) + ....+ a(n)

Then, the sum of the first n terms is given by:

S(n) = n/2 [a(1) + a(n)]

Parameters given in the problem:

a(1) = 4

S(40) = 6080

To find a(40), substitute n = 40, a(1) = 4, and S(40) = 6080 into the formula:

S(n) = n/2 [a(1) + a(n)]

S(40) = 40/2 [4 + a(40)]

6080 = 20 . [4 + a(40)]

Divide both sides by 20

304 = 4 + a(40)

Subtract 4 from both sides:

304 - 4 = 4 + a(40) - 4
