calculate the length of AD give your answer to three signifcant figures

Answer:

Step-by-step explanation:

we have a right triangle,

to find out the hypotenuse, h

H^2=13^2+4^2

H^2=169+8=177

The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building

As per the condition, We have a right triangle.

To find out the hypotenuse x

By Pythagoras theorem,

⇒ x² = 13² + 4²

⇒ x² = 169 + 8

Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.

Hence, the correct answer would be an option (A).

Look at the picture below. Sorry if its hard to understand.

The results for the addition operation are obtained as  84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The given problem can be solved as follows,

(a) 45²/₉ + 39³/₉

⇒ 45 + 2/9 + 39 + 3/9

⇒ (45 + 39) + (2/9 + 3/9)  = 84⁵/₉

(b) -24⁵/₉ + 30⁷/₉

⇒ -24 - 5/9 + 30  + 7/9

⇒ (-24 + 30) + (7/9 - 5/9)

⇒ 6²/₉

(c) 28.98 + (-52.22)

⇒ 28.98 - 52.22

⇒ -23.24

(d) 56.75 + 75.12

⇒ 131.87

The given arithmetic operation can be matched in the form of table as,

    Sum                                    Result

45²/₉ + 39³/₉                             84⁵/₉

-24⁵/₉ + 30⁷/₉                            6²/₉

28.98 + (-52.22)                     -23.24

56.75 + 75.12                           131.87  

Hence, the given numbers are added to give result as 84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

Step-by-step explanation:

The lines are parallel to one another.

A linear system of equations has no solution if the graphs are parallel and the two lines never meet.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

There can be one solution to a system of two linear equations, an infinite number of solutions, or no solutions at all. The number of solutions to a system of equations can be used to categorize it.

A system is deemed consistent if there is at least one solution to the problem. A consistent system is said to be independent if it only has one possible outcome.

Thus, a linear system of equations has no solution if the graphs are parallel and the two lines never meet.
