Answer:

<u>The vertical axis will start from 0 inches.</u>

Step-by-step explanation:

  • As data provides information that
  • 28% plant are under 6 inches.
  • 54% are between six and 8 inches.
  • 18% are above 8 inches.
  • So the least height is not mentioned only it is mentioned that below the 6 inches which means from 0 inches to six inches.
  • And in making bar graph vertical axis should start from least value.
  • Hence here possible least value is 0 inches.

<u>Answer:</u>

The vertical axis should begin with 0 inches.

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

The vertical axis must start with 0 inches to ensure accuracy for the measures of every plant since 28% of the plants in the garden are under 6 inches.

If the vertical axis begins with 6 inches or above, we can miss a lot of the gardener's data, especially the plants which are under 6 inches.

Therefore, to ensure that the graph does not mislead any measures of the plant, the vertical axis must begin with 0 inches.

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?
Karo-lina-s [1.5K]

Let us find the co ordinates of each vertex of the triangle .

Vertex A ( in firs second quadrant) = ( -5 ,3)

vertex B in third quadrant = ( -5, -5)

vertex C in fourth quadrant = ( 4, -2)

let us use distance formula AB^2 = ( -5 - 3)^2 + (-5 - -5 )^2 = 64 + 0

AB= 8

BC^2 = ( -2 - -5 )^2 + ( 4 - - 5)^2 = 9 + 81 = 90

BC = 9.48

AC^2 = ( -2 -3)^2 +( 4- -5)^2 = 25 + 81 = 106

AC= 10.29

Perimeter = sum of length of AB+ BC+ Ac = 8 + 10.29 + 9.48= 22.77

6x − y + z = −3<br> 4x − 3z = −13<br> 2y + 5z = 15<br> Find the solutions?
Alla [95]

Answer:

The solution of the equation are x = - 1 , y = 0 and z = 3

Step-by-step explanation:

Given three linear equation as :

6 x - y + z = - 3        ......A

4 x - 3 z = - 13           ......B

2 y + 5 z = 15            ......C

Solving eq A and C

I.e 2× (6 x - y + z ) = -3 ×2

or, 12 x - 2 y + 2 z = - 6

So, ( 12 x - 2 y + 2 z ) + ( 2 y + 5 z) = - 6 + 15

Or,  12 x + 7 z = 9         ......D

Solving eq B and D

I.e 3 × ( 4 x - 3 z ) = - 13 × 3

or, 12 x - 9 z = - 39

So, (   12 x + 7 z ) - ( 12 x - 9 z ) = 9 + 39

or,  16 z = 48

∴   z = \frac{48}{16}

i.e  z = 3

put the value of z in eq D

So, 12 x + 7×3 = 9  

Or, 12 x = 9 - 21

or,  12 x = - 12

∴   x = -  \frac{12}{12}

I.e  x = - 1

Now, Put The value of z in eq C

or, 2 y + 5 z = 15    

or,  2 y + 5 × 3 = 15

Or,  2 y = 15 - 15

or,  2 y = 0  

∴  y = 0

Hence The solution of the equation are x = - 1 , y = 0 and z = 3  Answer

Which graph represents the function f(x)=0.25x+5
ozzi

Answer:

Its the graph at the top left.

Step-by-step explanation:

Take the graph of f(x) = 0.25^x:

when x = 0 , f(x) = 1 so it will pass through the point (0,1). Also as x  increases f(x) will decrease because  the base 0.25 is < 1.  So  the graph will decrease to the right.

The + 5 in the function moves the whole graph up 5 units so the graph will pass through the point (0,  6).
