Answer 1

Answer:

Each of the domain values, x, should only output a single unique range value, y.

This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.

-1 outputs a 3

and

-1 outputs a 5

If I were to draw a vertical line at the domain value of -1 that vertical line would intersect the points (-1,3) and (-1,5). Which indicates that the relation

Letter b is the right answer {(1, 2), (2, 6), (3, -2), (4, -6), because the first ordered pairs are not repeated.

how do you solve graphs and make an equation from a line on a graph?​

Answers

Ans: To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.

Always start on the y-axis.

rise/run

First things first, you have to know your positives, negatives, zeros, and undefined.

To make an equation from the graph you have to know your formula.

y=mx+b

You do the rise first. The rise on the graph is 3. The run is 2. So, that'll make it 3/2. m=slope.

b=y-axis. b=1.

y=3/2x+1 (Example from the image)

sin70° sin130° sin170°=1/8​

Answers

Sin 10° Sin 50° sin 70° = 1/8
Now we multiply upper & bottom both side 2/2

then

➡ 1/2 (2sin 10° sin50° 70°)

➡ 1/2 sin10°( 2sin70° sin50°)

we know that
2 sinA sinB = cos (A-B) - cos (A+B)

Then

➡ 1/2 sin 10° ( cos 20° - cos 120°)

➡ 1/2 sin 10° ( cos 20° - cos (90°+30°))

➡ 1/2 sin 10° ( cos 20° +1/2)

➡ 1/2 sin 10° cos 20° +1/4 sin 10°

again we multiply both upper & bottom side 2/2 so

➡ 1/4 ( 2 sin 10° cos 20°). + 1/4 sin 10°

we know that
2 sinA cos B = sin (A+B) - sin (A- B)

➡ 1/4 (sin 30° - sin 10°) + 1/4 sin 10°

➡ 1/4 sin 30° - 1/4 sin 10° + 1/4 sin 10°

we know sin 30° = 1/2

➡ 1/4 × 1/2

➡ = 1/8 hence proved

Answers

Answer: 131

Step-by-step explanation:

The angle A inside the triangle is

180-162 = 18 degrees

The measure of angle N inside the triangle is

180 -  149 = 31 degrees

Now, since we have the inside angles we can find ang P

Inside Ang A + Inside Ang N + Ang P = 180

18 + 31 + P = 180

49 + P = 180

P = 180 - 49

P = 131 degrees

Why is 64 a perfect square, but 60 is not?

Answers

Answer:

Step-by-step explanation:

because it needs to be a number times itself to be be a perfect square

Answer:

The square root of 64 gives the original number. If you square 8, you get 64, making it a perfect square. However, 60's square root is only approximate to 60 and very close to it when squared. Therefore, it cannot be a perfect square.

choose the number that is larger than: 1.11 x 10 a.90,000,000,000 b.5.66 x 10 c.1.01 x 10 d.1.01 x 10

Answers

This number is greater than our solution to 1.11 * 10^12.

What are exponent and examples of them?

The number of times a number has been multiplied by itself is referred to as an exponent. For instance, the expression 2 to the third (written as 23) signifies 2 x 2 x 2 = 8. 23 and 2 x 3 = 6 are not equivalent. Keep in mind that any number is itself when raised to the power of 1.

First we need to find the value of 1.11 * 10^12.

We need to solve the exponent first.

10^12 = 1000000000000

Next, we will multiply this by 1.11.

1,000,000,000,000 * 1.11 = 1,110,000,000,000

The value of 1.11*10^12 is equal to 1,110,000,000,000.

We can immediately rule out a), 90,000,000,000 as an answer. We can easily tell that out solution is greater than this answer.

Now we will find the value of option b).

5.66 * 10^11.

We need to solve the exponent first.

10^11 = 100000000000

Next, we will multiply this by 5.66.

100,000,000,000 * 5.66 = 566,000,000,000

This number is not greater than our solution to 1.11 * 10^12. Therefore, option b) is not your answer.

Now we will find the value of option c).

1.01 * 10^13.

We need to solve the exponent first.

10^13 = 10,000,000,000,000

Next, we will multiply this by 1.01.

10,000,000,000,000 * 1.01 = 10,100,000,000,000

This number is greater than our solution to 1.11 * 10^12. Therefore, option c) is your answer.

Three different coins are tossed. What is P(tail, head or tail, head, or tail)

Answers

Answers:

Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]

Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]

Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]

Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]

Step-by-step explanation (Read Carefully):

-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:

-A way to organize this is to have:

H = heads

T = tails

-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):

HHH

HHT

HTH

HTT

THH

THT

TTH

TTT

Now, let’s apply some questions:

Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].

Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].

Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].

Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]

Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

Step-by-step explanation:

I'm not 100% correct, but you set the other two angles to add to each other then set it equal to angle QRS and i got x=6.

Your equation should be like this: 3x + 17 + 2x +21 = 10x -1

than you solve form there

I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps

Answer:

59°

Step-by-step explanation:

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]

So, by exterior angle property of a triangle, we have:

[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\

(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\

(10x - 1)\degree = (3x +17+2x +12)\degree\\\\

(10x - 1)\degree = (5x +29)\degree\\\\

(10x - 1)= (5x +29)\\\\

10x - 5x = 29 + 1\\\\

5x = 30\\\\

x = \frac{30}{5}\\\\

x = 6\\\\

\because m\angle QRS = (10x - 1)\degree \\\\

\therefore m\angle QRS = (10\times 6- 1)\degree \\\\

\therefore m\angle QRS = (60- 1)\degree \\\\

\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\

B. 10x + 2 = (10 + 2)x - 2x
C. 10x + 2x = (10 + 2)x
D. 10x + 2 = (10 + 2)x

Answers

Answer:

We conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

Step-by-step explanation:

A.

10x + 2x = (10 + 2)x - 2

Checking the equation in Part A

10x + 2x = (10 + 2)x - 2

10x + 2x = 10x+2x-2

10x + 2x - 10x - 2x = -2

0 = -2

The sides are not equal.

Hence, NO SOLUTION!

B.

10x + 2 = (10 + 2)x - 2x

Checking the equation in Part B

10x + 2 = 10x+2x - 2x

10x + 2 - 10x - 2x + 2x = 0

2 = 0

The sides are not equal.

Hence, NO SOLUTION!

C.

10x + 2x = (10 + 2)x

Checking the equation in Part C

10x + 2x = 10x+2x

10x + 2x - 10x - 2x = 0

0 = 0

Both sides are equal.

It is true for all x.

D.

10x + 2 = (10 + 2)x

Checking the equation in Part D

10x + 2 = 10x+2x

10x - 10x - 2x = -2

-2x = -2

Divide both sides by -2

x = 1

Hence, 10x + 2 = (10 + 2)x has only 1 solution.

Therefore, we conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

Based on the map, what is the shortest distance, to the nearest tenth, from the Library to the Gas Station if each unit represents one mile?

Answers

It is found that location of Sam's house is at a distance of approximately 8.062 meters far from the gas station.

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Sam's house S(x, y) = (2, -4)

Library L(x, y) = (-5 , 2)

Gas station  G(x, y) = (3, 4)

The distance d, in miles, is determined by the line segment distance formula:

D = √[(x-p)² + (y-q)²]  

It is used in an operation known as dot product.

Then the distance between Sam's house and the Gas station is:

D = √[(2 - 3)² + (-4 -4)²]  

D = 8.062 meters

Hence, The location of Sam's house, is at a distance of approximately 8.062 meters far from the gas station.

Answer:

-1 5/6

Step-by-step explanation:

-2/3 + (-1 1/6)

Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.

Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.

-2/3 * 2/2 = -4/6

-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.

Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.

Answer: -2/3 + (-1 1/6) = -1 5/6
