Answer:

A function is a relation that is either

  1. one-to-one, meaning each output only has one input
  2. many-to-one meaning some outputs can have more that one input, but all inputs only have one output

So, That pic is cramped, don't even know what functions are being referenced but

from the a, b, c, d relation

  • It is not a function because some inputs have more that one output, which fails our man-to-one rule

From the equations

  • -3x = 15 is not a function, because it only has one input but more than one output breaking rule 1
  • 2y=10 is a function because every input x has only one output y, it is many-to-one
  • 3x-0.25y=3 is a function, it is one to one

From the graph

  • the line is a function, since it is many-to-one

From the points

  • the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a function

When rounded to the nearest 100 I am the smallest number that becomes 5000
SIZIF [17.4K]

Answer:

4950

Step-by-step explanation:

The smallest number when rounded to the nearest 100 that becomes 5000 should be between the range of 4950 and 4999.

To the round any figure to the nearest hundred, the \bold{tens digit} of the number should be considered. If the number ranges from 1 to 49, it should be rounded to previous hundred, but if the number is between the range of 50 to 99, it should be rounded to the next 100.

Therefore the smallest number when rounded to the nearest 100 that becomes 5000 is 4950

3 plss help <br> Solve for x<br> ...........
Delicious77 [7]

They are alternate interior angles so they add up to 90.

8x-4+60 = 90 would be the equation.

Now, just combine the like terms.

8x+56 = 90

8x = 34

x = 4.25

in Haritha haram,108,84 and 60 saplings of mango guava and sapota are supplied .find the minimum number of rows in which they ca
pishuonlain [190]

Answer: 21

Step-by-step explanation:

Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.

Since, 108 = 2 x 2 x 3 x 3 x 3

84 =  2 x 2 x 3 x 7

60 = 2 x 2 x 3 x 5

HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]

= 12

Greatest number of plants in each row = 12

Number of rows for mango = \dfrac{108}{12}=9

Number of rows for guava = \dfrac{84}{12}=7

Number of rows for sapota = \dfrac{60}{12}=5

Total rows = 9+7+5= 21

Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted​ = 21

What is the equation of the circle with center (1, 1) that passes through the point (−3, 4)?
Alex_Xolod [135]

Answer:  (x - 1)² + (y - 1)² = 25

<u>Step-by-step explanation:</u>

The formula for a circle is     (x - h)² + (y - k)² = r²     where

  • (h, k) is the center
  • r is the radius

Typically, you are given the center and the radius.  In this problem, you are given (x, y) so you must plug that into the equation to find r².

Given: (x, y) = (-3, 4)   and   (h, k) = (1, 1)

                       (-3 - 1)² + (4 - 1)² = r²

                         (-4)²    +   (3)²   = r²

                          16      +    9     = r²

                                  25         = r²

Next, input (h, k) and r² into the equation

                  (x - 1)² + (y - 1)² = 25

Simplify the ratio 40cm:2m
kakasveta [241]
First, convert 2m into cm by multiplying by 100 so the ratio is now 40:200, then 40 goes into 200 5 times so the ratio is 1:5. Hope that helped!
