Please Help! For Each Of The Following Relations, Identify Whether Its A Function Or Not And Why, Then

Answers

Answer 1

Answer:

The first one is a function, the second one is a function, and the third one is not a function.

Domain for the first one, just list the x values. Same for range.

Domain and range for the second one are both all real numbers.

For the last one, solve the quadratic, and find the vertex. The range will be all numbers greater than the y on the vertex, while the domain is all real numbers.

Step-by-step explanation:

An easy way to tell if something is a function or not is to check that each input (or x-value) has a different output (or y-value.) The first one is not a function because in the table, we see that 1 gives an output of 9, but later on you see 1 also gives an output of 20.

If you're ever given a graph and asked this question, do the vertical pencil test. Start at the left of the graph, and slide your pencil over the graph (vertically) and if your pencil ever hits more than one point at a time, it's not a function. Hope this helped!

The scale of a map is 4 ft = 13 mi. If the actual distance between two cities is 45.5 miles, what is that

Answers

14 feet because 13 times 3 is 39 4 times 3 is 12 and half of 13 is 6.5 and 39+ 6.5 is 45.5 so 12+2 (half of 4) is 14 so it’s 14 feet

64° because the equation would be everything added equal to 360 so 180+90+26+x=360 so when you solve 296+x=360 , then you subtract 297 from both sides so you end up with x=64

Answer: x=64°

Step-by-step explanation:

According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.

26+x+90=180            [combine like terms]

116+x=180                  [subtract both sides by 116]      

x=64°

Now, we know that x=64°.

On the other hand, we can see that 26+x=90. We can also use that to solve for x.

26+x=90                    [subtract both sides by 26]

x=64°

Please please help asap!!!! Solve for the indicated variable. 3a + 6b = 4 for b

Answers

Answer:

b = (4/6) - a/2

Step-by-step explanation:

6b + 3a = 4

6b = 4 - 3a

b. = (4 - 3a)/6

b. = (4/6) - a/2

The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

In the provided expression, variable and constant are there

It is given that:

The equation in a and b, where a and b are the variables:

3a + 6b = 4

Here the indicated variable is b.

To find the value of b in terms of a make the subject as b:

Subtract 3a on both the sides in the equation 3a + 6b = 4:

The equation becomes:

3a + 6b -3a = 4 - 3a

6b = 4 - 3a

Divide by 6 on both sides:

The equation becomes:

6b/6 = (4 - 3a)/6

b = (4 - 3a)/6

Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

in this you basically just isolate the variable which means that you get rid off all the numbers that are applied to the varible by preforming the opposite opperation. In this case if you subtract 2 from both sides, the 2 on the left gets cancelled out and the -2 on the right turns into -4, so your equation would look like y=-4

What is the greatest number that will divide 307 and 330 having the reminder 3 qnd 7

Answers

Answer:

19.

Step-by-step explanation:

Answer:

The required number  = 19

Step-by-step explanation:

307 - 3 = 304

330 - 7 = 323

Find GCF of 304 & 323

304 =  2* 2 *2 * 2 * 19

323 = 17 *19

HCF = 19

The required number  = 19

When you divide 307 by  19, you will get an remainder 3

When you divide 330 by  19, you will get an remainder 7

Answer: (1) -3/4   (2) 7     (3) y = (-3/4)x + 7     (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

   from (0, 7) to (4, 4) is: down 3 and right 4   →   m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

   The line crosses the y-axis at (0, 7)    →   b = 7    

3) Slope-Intercept form is y = mx + b

   m = -3/4  and b = 7     →      y = (-3/4)x + 7

4)  COUNT the number of spaces from one point to the other point.

 from (-2, -4) to (2, -2) is: up 2 and right 4   →   m = 2/4  = 1/2 when simplified

Answers

Answer:

See below.

Step-by-step explanation:

We have:

[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]

And we want to find two different angles between 0 and 180 that satisfy this equation.

First, let's get our sine out of the denominator. Notice that this is the same as:

[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]

Cross-multiply:

[tex]2\sin(\theta)=\sqrt{3}[/tex]

Divide both sides by 2:

[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]

Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!

#2 is correct. However, double check #3. The answer's down there too... :)

[Blank space...]

[More blank space...]

[And more...]

Answer for 1)

We have:

[tex]\sin(\theta)=\sqrt{3}/2[/tex]

So, at what points between 0 and 180 does sine equal √3/2?

If we refer to the unit circle, we can see that this happens twice: at 60.

Thus, the second time it occurs will be at 180-60 or 120.

So:

[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]

Answer for 3)

So you are correct for the first three. So:

[tex]\sin(54)=t[/tex]

However, sine stays positive. So, our angle must be between 0 and 180.

So, instead of 180+54, it should be 180-54, giving us:

[tex]\sin(54)=\sin(126)=t[/tex]
