question:
1. Use the Pythagorean theorem to find AD.
2. Find AC. Show your work.
3. Is ΔABC a right triangle? Explain.
SHOW YOUR WORK

Answers

Problem 1

Answer: AD = 9

-------------------------------------------------

Work Shown:

Focus on triangle ADB, which is the smaller triangle on the left.

We have these side lengths

AD = unknown leg

BD = 12 = known leg

AB = 15 = known hypotenuse

Let's apply the Pythagorean Theorem to find the unknown leg

a^2 + b^2 = c^2

(AD)^2 + (BD)^2 = (AB)^2

(AD)^2 + (12)^2 = (15)^2

(AD)^2 + 144 = 225

(AD)^2 = 225-144

(AD)^2 = 81

AD = sqrt(81)

AD = 9

Side AD is 9 units long.

========================================================

Problem 2

Answer: AC = 25

-------------------------------------------------

Work Shown:

AC = AD + DC .... segment addition postulate

AC = 9 + 16 ..... substitution; refer to problem 1

AC = 25

========================================================

Problem 3

Answer: Triangle ABC is a right triangle.

-------------------------------------------------

Work Shown:

The Pythagorean Theorem Converse says "if a^2+b^2 = c^2 is a true equation, then the triangle with sides a,b,c is a right triangle". Keep in mind that c is always the longest side (hypotenuse). The order of 'a' and b doesn't matter. Convention has us usually do [tex]a \le b[/tex] but again the order isn't important.

We have these three sides

a = 15 (length of side AB; leg #1)b = 20 (length of BC; leg #2)c = 25 (length of AC; hypotenuse)

Plug those values into the equation below. Simplify each side.

a^2+b^2 = c^2

15^2 + 20^2 = 25^2

225 + 400 = 625

625 = 625

We get a true equation. Therefore, triangle ABC is a right triangle.

Answer:

Step-by-step explanation:

Pythagorean = c^2 =a^2 + b^2

we are given c and a so solve for b

c^-a^2 = b^2

15^2- 12^ = b^2

81= b^2

[tex]\sqrt{81}[/tex]=b

9=b

AD=b

AC = AD + 16

AC =9 + 16 =25

if it's a right triangle then Pythagorean will work with the sides to make 25

AC^2 = 15^2+20^2

AC = [tex]\sqrt{625}[/tex]

AC = 25

What is the composition of white light and how is it related to solar radiation?

Answers

Answer:

The spectrum of white light consists of six basic colours arranged in a specific order: red, orange, yellow, green, blue and violet. Although Newton understood that a beam of light of a particular colour is always deviated by the same amount, he did not appear to understand why this is so.

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Answers

Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.

Answer:no

Step-by-step explanation:

Because u can not subtract a denominator from numerator u must subtract the denominator by the denominator

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol.

Given that the phrase "add 3 to 6, then multiply the result by 5"

Then first add 3 and 6 = 3 + 6

To indicate the multiplication sign we will use x.

Now multiply the result by 5;

(3 + 6 ) x 5

Hence, the expression for the sequence of operations would be; (3 + 6 ) x 5.

A school club sold 300 shirts. 31% were sold to fifth graders, 52% were sold to sixth graders, and the rest were sold to teachers. How many shirts were sold to each group-fifth graders, 6th graders, and teachers? Explain or show your reasoning. Please help I'm late on turning in homework!

Answers

Answer:

5th graders = 93 people 6th graders = 156 teachers = 51

Step-by-step explanation:

93 5th graders bought shirts, 156 6th graders bought shirts, 51 teachers bought shirts

300x0.31 = 93 shirts sold to 5th graders
300x0.52 = 156 shirts sold to 6th graders
156+93 = 249 shirts sold to students
300-249 = 51 shirts sold to teachers

The dot plot shows predictions for the winning time in the 200-meter sprint. The winner finished the race in 22.3 seconds. What is the greatest percent error among the predictions?

Answers

Answer:

3.2%

Step-by-step explanation:

Answer:

The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Step-by-step explanation:

Given that,

The dot plot shows predictions for the winning time in the 200-meter sprint.
The winner finished the race in 22.5 seconds.

We have to determine,

What is the greatest percent error among the predictions.

According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds.

Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)

Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).

Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

The US controlled trade in much of the Western Hemisphere, and used their immense military power to police trade in the region. The phrase, as depicted in the cartoon, speak softly and carry a big stick, means that America should negotiate, but also show that they have a lot of military strength, without actually doing anything, unless absolutely necessary. B) One similar way trade was organized in the same time period to benefit Europe was that European powers used their military strength to pressure other countries into trading with them. This was similar to the big stick policy, but they established colonies and controlled trade through that. European powers also forced Asian countries to establish ports so that they could trade there. The fundamental principles of both the American big stick policy and its European counterpart are the same, as they control trade in the regions they want to trade in with their military strength and influence. C) One consequence of this for one of the examples used in problem A is that American merchants and companies were able to have a lot of economic control in other regions, and their profits increased as they gained more control of trade in the regions they aimed to control. With economic control of a region, also comes a certain degree of political control, so many US companies used their control to influence political decisions in their favor. For example, the United Fruit Company used their economic control over some portions of South America, and inhibited the development of countries in South America like Guatemala. 2 box plots.
