Determine whether each relation is a function and give a reason?
1. {(24, 1) , (21 , 4 ) , (3 , 22) , (24 ,5)}
2. y= x + 3

Answer:

f(-10) = -2

Step-by-step explanation:

[tex] y =\frac{20}{x}[/tex]

[tex]\implies f(x)=\frac{20}{x}[/tex]

[tex]\implies f(-10)=\frac{20}{-10}[/tex]

[tex]\implies f(-10)=-2[/tex]

Answer:

-2

Step-by-step explanation:

sub -10 in place of x and divid to give you -2

Answer:

2*2*3*5

Step-by-step explanation:

Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.

I think its 71, but I am not 100% sure. Take this as a secondary answer.

Answer:

C. 71°

Step-by-step explanation:

If angles 4 and 12 are equal and complementary, then they measure 45°

There is a triangle formed by angles 3, 11 and 12

the angle 3 = 64°, angle 12 = 45°

Then by the property of triangles:
angle 11 = (180 - 64 - 45)° = 71°

Answer:

123 more muffins

Step-by-step explanation:

To find out how many to box in total you would do 14 x 12 = 168

168 - 45 = 123

Since 45 were already boxed, 123 more would be needed to make 14 boxes.

Answer:

One cubed shape block volume = 0.125 cubic feet

Step-by-step explanation:

Since the edge length of each block is 1/5 the edge length of the storage container, we do this:

1/5 x 2.5 = 0.5

Now we know that the edge length of each block is 0.5 feet. To find the volume of it, we do this:

0.5^3 = 0.125

The volume of one cubed shape block is 0.125 cubic feet.

Answer:

[tex]\longrightarrow: \boxed{\sf{x=-6}}[/tex]

Step-by-step explanation:

Isolate the term of x from one side of the equation.

First, you subtract by 19 from both sides.

⇒ x+19-19=13-19

Solve.

Add/subtract the numbers from left to right.

⇒ 13-19=-6

⇒ x=-6

I hope this helps! Let me know if you have any questions.

Answer:

Step-by-step explanation:

In the question we're given with an equation that is x + 19 = 13 and we have asked to find the solution of equation that means we have to find the value of x .

Solution :

[tex] \longmapsto \: x + 19 = 13[/tex]

Subtracting 19 on both sides :

[tex] \longmapsto \: x + \cancel{19} - \cancel{19 }= 13 - 19[/tex]

On further calculations we get :

[tex] \longmapsto \: \blue{ \boxed{x = - 6}}[/tex]

Verifying :

We are verifying our answer by substituting value of x in the given equation .

Therefore our value for x is correct .

[tex]36^6[/tex] postcodes

Step-by-step explanation:

Think of the post code as a combination lock

[?] [?] [?] [?] [?] [?]

If letters a numbers are allowed, each character can be A-Z and 0-9.

There are 26 letters, and 10 different digits

26 + 10 = 36 characters

Each block (I illustrated above) can be any of the 36 characters

If you have 2 blocks, you have a combination of

36 x 36 characters — which is the same as [tex]36^2[/tex]

With 3 blocks: [tex]36^3[/tex]

and so forth...

If your post code is made of 6 'blocks' it can be any combination of

Answer:

ρ =45% or 0.45

ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%

Step-by-step explanation:

ρ represents the population proportion of the bus riders, with a monthly pass, who are students.

The population proportion is simply the percentage of the entire population with a particular characteristic. We have been informed that in a city, 45% of the bus riders with a monthly pass are students. This means that 45% of the whole population of bus riders with a monthly pass are students. Therefore, our ρ is simply 45% or 0.45.

ρ with ^ represents the sample proportion of the bus riders, with a monthly pass, who are students. This is a statistic or an estimator as it is normally used to estimate the value of ρ, the population proportion. It is calculated using the formula;

ρ with ^ = [tex]\frac{x}{n}[/tex]

where n represents the size of the sample and x the number of individuals in the sample with a certain desired characteristic. We have been informed that;

in a random sample of 50 bus riders with monthly passes, 18 are students.

Using the above formula and the values given we have;

ρ with ^ = [tex]\frac{18}{50} =0.36[/tex] or equivalently 36%

10n² + 3n + 7

Step-by-step explanation:

2A - 3B = 2.( -1 + 5n² + 9) - 3.(3 - n)

= -2 + 10n² + 18 - (9 - 3n)

= 10n² + 16 -9 + 3n

= 10n² + 3n +7

Answer:

210

Step-by-step explanation:

126 is 60% of What Number? - 126 is 60% of 210. 100% of 210 is 210, therefore 60 percent of 210 equals 126.

Formula = Number x 100

Percent = 126 x 100

60 = 210

Following shows the steps on how to derive this formula and find out 60% of what number is 126.

Step 1: If 60% of a number is 126, then what is 100% of that number? Setup the equation.

126

60% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

60Y = 126 x 100

60Y = 12600

Y = 12600

100 = 210

What is  126 % of 60 ? = 210

Answer: …

Step-by-step explanation:

Well, 126 is 60% of 210. 100% of 210 is 210, therefore 60 percent of 210 equals 126

The time it will take to roll from the top of the ramp to the bottom by the ball when acceleration of it a = 2 ft/s2, is 4 seconds.

The equation of motion is the relation between the distance, velocity, acceleration and time of a moving body.

The equation which gives the distance d of an object starting at rest travels given acceleration a and time t is,

[tex]d = \dfrac{1}{2}at^2[/tex]

Suppose a ball rolls down the ramp shown at the right with acceleration a = 2 ft/s2. The ramp is 12 feet long. Thus, the distance travel by ball to roll from the top of the ramp to the bottom is 12 feet. Thus, we have,

[tex]a=2\rm\; ft/s^2\\d=12\rm\; feet[/tex]

Put the values in the above equation,

[tex]d = \dfrac{1}{2}at^2\\12 = \dfrac{1}{2}(2)t^2\\t^2=12\\t=\sqrt{12}\\t=3.46\\t=\approx 4\rm\; s[/tex]

Thus, the time it will take to roll from the top of the ramp to the bottom by the ball when acceleration of it a = 2 ft/s2, is 4 seconds.
