check if given set of numbers 6,8,10 forms pythagorean triplet or not?
Answers
[tex] \LARGE{ \underline{ \tt{Required \: answer:}}}[/tex]
We know that,
Pythagoras theoram is given by : p² + b² = h²In a Pythagoras triplet, the longest side represents the hypotenuse of the triangle.Then,
We should check that, whether the sum of squares of the smaller sides will be equal to the square of the third side or not. Then, we can determine the above easily.
Sum of squares of smaller sides:
= 6² + 8²
= 36 + 64
= 100
Square of longer side:
= 10²
= 100
Sum of squares of smaller sides = Square of longer side. Hence, 6,8,10 are Pythagorean triplets.
And we are done! :D

e. Find the length of sides of the triangle whose vertices are A (7,4), B (-8, 6) Ć(1, -3).
Answers
Answer:
Length of sides of triangle are: AB = 15.13, BC = 12.72, AC = 9.21
Step-by-step explanation:
We need to find the length of sides of the triangle whose vertices are A (7,4), B (-8, 6) C(1, -3).
We have three sides of triangle AB, BC and AC
The length of side can be calculated using distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Now finding lengths of sides AB, BC and AC
i) Length of side AB
We have A (7,4), B (-8, 6)
and [tex]x_1=7, y_1=4, x_2=-8, y_2=6[/tex]
Putting values in formula and finding length
[tex]Length \ of \ side \ AB \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ AB \ =\sqrt{(-8-7)^2+(6-4)^2}\\Length \ of \ side \ AB \ =\sqrt{(-15)^2+(2)^2}\\Length \ of \ side \ AB \ =\sqrt{225+4}\\Length \ of \ side \ AB \ =\sqrt{229}\\Length \ of \ side \ AB \ =15.13[/tex]
So, Length of side AB is 15.13
ii) Length of side BC
We have B (-8, 6) and C(1, -3)
and [tex]x_1=-8, y_1=6, x_2=1, y_2=-3[/tex]
Putting values in formula and finding length
[tex]Length \ of \ side \ BC \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ BC \ =\sqrt{(1-(-8))^2+(-3-6)^2}\\Length \ of \ side \ BC \ =\sqrt{(1+8)^2+(-9)^2}\\Length \ of \ side \ BC \ =\sqrt{(9)^2+(-9)^2}\\Length \ of \ side \ BC \ =\sqrt{81+81}\\Length \ of \ side \ BC \ =\sqrt{162}\\Length \ of \ side \ BC \ =12.72[/tex]
So, Length of side BC is 12.72
iii) Length of side AC
We have A (7,4)and C(1, -3)
and [tex]x_1=7, y_1=4, x_2=1, y_2=-3[/tex]
Putting values in formula and finding length
[tex]Length \ of \ side \ AC \ =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\Length \ of \ side \ AC \ =\sqrt{(1-7)^2+(-3-4)^2}\\Length \ of \ side \ AC \ =\sqrt{(-6)^2+(-7)^2}\\Length \ of \ side \ AC \ =\sqrt{36+49}\\Length \ of \ side \ AC \ =\sqrt{85}\\Length \ of \ side \ AC \ =9.21[/tex]
So, Length of side AC is 9.21
So, length of sides of triangle are: AB = 15.13, BC = 12.72, AC = 9.21

A 14-ounce energy drink contains 10 1/2 teaspoons of sugar. How much sugar is in one ounce of the drink?
Answers
Answer:
0.75 or 3/4
Step-by-step explanation:
10 1/2 teaspoons of sugar ÷ 14 oz energy drink = ?
10.5 teaspoons of sugar ÷ 14 oz energy drink = 0.75 teaspoons of sugar per drink
OR (fraction way):
10 1/2 ÷ 14 = ?
First, Convert any mixed numbers to fractions. Then your initial equation becomes:
21/2 ÷ 14/1 = ?
Apply the fractions formula for division (just flip the second fraction and multiply):
21/2 x 1/14 = 21/28 = 3/4 = 0.75

What is the equation of the line perpendicular to y=-1/5x -2 and contains the point (2, -10)?
Answers
Answer:
y= 5x-20
Step-by-step explanation:
I didn't understand if I had to find the perpendicular line or parallel haha.
You’re welcome :)
Answer:
y = 5x -20
Step-by-step explanation:
for the line to be perpendicular it must have the inverse slope
therefore m = 5
no substitute the point (2, -10) in for (x, y) respectively to find the y intercept
-10 = 5(2) + b
-10 = 10 + b
b = -20
the equation will be y = 5x -20

Question 2 answer: The value of the angles is 76.
Question 3 answer: The value of the angle is 36.
Question 4 answer: all angles in the figures are classified as acute angles
Step-by-step explanation:
First all of, using one of the triangle rules, both the angles are congruent. Then, because both 1 and 2 are the same and the triangle in 1 already have the other two angles, use 180 - 85 - 19 and get 76. Lastly moving on to the other triangle, same method, 180 - 76 -68 and get 36. Because all these angles are less than 90 degrees and anything less than 90 is considered to be acute.

Answers
Answer:
slope intercept form: y=mx+b
y+3=2(x+5)
step 1: use distributive property
y+3=2(x)+2(5)
y+3=2x+10

Dynamic equilibrium
Step-by-step explanation:
Dynamic equilibrium in the human body is achieved when there is an internal control which tends to oppose certain outside forces which could affect the body. It's known to be the ability to detect and respond to stimuli by living organisms. When these stimuli occur, there are feedbacks or responses that are sent or received by the body to maintain stability. This dynamic equilibrium of the internal environment can also be seen as homeostasis.

Step-by-step explanation:
For example the third croses at 5 thats the y-intercept. Know notice how you go up once and run two blocks for the slope. So the slope is 1/2x.
Answer for #3 y=1/2x+5
Note. Anytime you are running down the slope will be negative. If the line points up then its positive.
Answers should be in this form: 1) positive 2. negative 3. positive 4. negative 5. positive 6. negative
Answer:
1. slope = 4 over 2(2), y int = -8
2. slope = 2 over 3 , y int = 2
3. slope = 3 over 6(1/2), y int = 5

Answers
Answer:
G
Step-by-step explanation:
The expression that expresses her purchasing restrictions is:
13c + 10d = 150.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given, Cheyenne is deciding between the ways she has to buy music. Albums on CD cost $13 but downloads of an album only cost $10. If she can spend up to $150 on music purchases.
Let "c" be the CDs she bought
and "d" be the albums she downloads
Price of total CD = 13c
price of total download = 10d
Thus, an equation that satisfies the situation:
13c + 10d = 150
therefore, Her purchasing limitations are expressed in the following way:
13c + 10d = 150.
