Three arithmetic means between 3 and negative 13

Answers

Answer 1
Answer:

Answer:

- 9, - 5, - 1

Step-by-step explanation:

Calculate the mean of 3 and - 13, that is

(3-13)/(2) = (-10)/(2) = - 5

That is

- 13, - 5, 3

Now find the mean of - 13 and - 5, and - 5 and 3

(-13-5)/(2) = (-18)/(2) = - 9

(-5+3)/(2) = (-2)/(2) = - 1

Thus

- 13, - 9, - 5, - 1, 3

create three different drawings showing a number of circles and triangles in which the ratio of circles to triangles is 2:3

Answers

Answer:

The required drawings is shown in figure 1, 2 and 3.

Step-by-step explanation:

Consider the provided information.

Let say x is the number of circles in the drawing.

y is the number of triangles in the drawing.

we know that

r= (x)/(y)

r= (2)/(3)

See the figure 1

In the figure 1  we have  2 circles and 3 triangles:

 x=2  and  y=3

The ratio will be :

r= (2)/(3)

See the figure 2

In the figure 2  we have  4 circles and 6 triangles:

 x=4  and  y=6

The ratio will be :

r= (4)/(6)=(2)/(3)

See the figure 3

In the figure 2  we have  6 circles and 9 triangles:

 x=6  and  y=9

The ratio will be :

r= (6)/(9)=(2)/(3)
o= circle and ^= triangle

WILL GIVE BRAINLIEST ANSWER! Given the parent function f(x)=|x|, which equation would occur if the function is vertically compressed by 13, shifted down 6 units, and shifted right 5?


f(x)=3|x+5|−6



f(x)=13|x−5|−6



f(x)=13|x+5|−6



f(x)=13|x−6|+5

Answers

f(x)=13|x-5|-6 is the equation represented by all the operations.

Step-by-step explanation:

The given function is

f(x)=|x|

It is vertically compressed by a factor of 13 then the function becomes,

f(x)=13|x|

It shifted down 6 units, then the function becomes,

\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}

It shifted right by 5 units then the function becomes,

f(x)=13|x-5|-6

Thus the resultant equation thus obtained is  f(x)=13|x-5|-6

8000 pounds is 4 tons then what is 7000 equal to?

Answers

Steps:
1. Do a proportion
8000 pounds/4 tons= 7000 pounds/ x
2. Do 7,000 times 4 which equals 28,000
3. Do 28,000 divided by 8,000
4. Your answer is
3.5 tons

Create a proportion: 8000/4 = 7000/x

8000x = 28000

then divide

8000x/8000 = 28000/8000

that equals x = 3.5 tons

---------------------------------------------------------OR---------------------------------------------------

Create a proportion 8000/4 = 7000/x

then simplify to 2000/1 = 7000/x

7000 = 2000x

then divide

7000/2000 = 2000x/2000

3.5 tons = x
