A recycling plant processes an average of 1/3

1 answer:

8 0

The solution to this problem is to convert 1/3 tons/minute to the number of tons/day.

This is done by multiplying 1/3 tons/minute by 60 minutes/hour and by 24 hours/day.

Looking the units of measure, we see that the minutes will cancel and the hours will cancel; and we will be left with tons/day. To determine how many, multiply (1/3) x 60 x 24. I will leave the calculation to you, but you should get 480.

Answer:

Option (2)

Step-by-step explanation:

In an arithmetic progression,

$a_1,a_2,a_3.........a_{n-1},a_n$

First term of the progression,

a = $a_1$

Common difference 'd' = $(a_2-a_1)$

Recursive formula for the sequence,

a = $a_1$

$a_n=a_{n-1}+d$

By applying these rules in the recursive formula,

$a_1=\frac{4}{5}$

$a_n=a_{n-1}+\frac{3}{2}$

Common difference 'd' = $\frac{3}{2}$

Therefore, Option (2) will be the answer.

Quick please help!!!!

From the equation, we have

$h=-20, k =21 , a^2=20^2, b^2=21^2$

To find the vertex and focus, we have to use the following formula

$Vertices =(h, k+-a) \\ Focii = (h,k+-c)$

And

$c = \sqrt{a^2 + b^2} = \sqrt{400+441} = 29$

So, we have

$Vertices=(-21,20+-20) \\ Focii=(-21, 20+-29)$

$Vertices =(-21,0),(-21,40) \\ focii=(-21,-9),(-21,49)$

How do you even solve these?

The equation takes the x coordinate of the vertex and puts it into an equation in vertex form with the y coordinate and the radius. The radius is entered as its squared value. The general form of a circle is (x-h)^2 + (y-k)^2 = r^2. So yours would look like this: (x-3)^2 + (y+2)^2 = 25
