<span>1.2312 x 10^13
A million is 10^6
A Billion is 10^9
A trillion is 10^12
12.312 trillion is 12.312 x 10^12 which is the same as 1.2312 x 10^13</span>

12.312 trillion.

A trillion has 12 zeros.

12.312 * 10¹²

1.2312*10¹*10¹²

= 1.2312 * 10¹⁺¹²

= 1.2312 * 10¹³

In scientific notation.

I hope this helps.

Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20
Kipish [7]

Answer:

Step-by-step explanation:

I think the below is your full question:

<em>Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20 hours per week. Graph two inequalities that Kishi can use to determine how many hours he needs to work at each job if she wants to earn at least $90 per week.</em>

Here is my answer:

Let x is the number of hours he works at the grocery store

Let y is the number of hours he works at the newspapers

We have two inequalities:

1/ x + y \leq 20 <=> y \leq 20 - x

2/ 7x + 10y \leq 90 <=> y \geq 3/4x + 12.5

Please look at the attached photo

The red line is y \leq 20 - x

The blue line is:  y \geq 3/4x + 12.5

Find the equation for the circle with a diameter whose endpoints are (3,-1) and (-2,-1)
cricket20 [7]

Answer:

The equation for the circle is: (x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2

Step-by-step explanation:

Here, let us assume the two end points of the diameter are:

P (3,-1) and Q (-2,-1)

Now, as we knew diameter is the chord that passer through the center of the circle.

⇒ Mid point of DIAMETER  = Center coordinates  of the Circle

Let us assume O(x,y) is the center of the line  segment PQ.

So, by MID POINT FORMULA:

(x,y)= (\frac{3 -2}{2}  , \frac{-1-1}{2} )  =( \frac{1}{2},\frac{-2}{2})  \\\implies (x,y) =( 0.5  , -1)

⇒ The center coordinates of the circle  = O(0.5,-1)   ...... (1)

Now, RADIUS = Half of DIAMETER

Using DISTANCE FORMULA:

PQ  = \sqrt{(3-(-2))^2 + (-1 - (-1))^2}   = \sqrt{(5)^2 + 0}  = 5

So, Radius  = 5/2  = 2.5 units

Now, the  equation of circle with radius r and center coordinate ( h,k) is given as: (x-h)^2 + (y-k)^2 = r^2

Substitute r = 2.5 and (h,k)  = (0.5,0) we get:

(x-0.5)^2 + (y-0)^2 = (2.5)^2\\\implies (x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2

Hence the equation for the circle is: (x-\frac{1}{2} )^2 + y^2 = (\frac{5}{2} )^2

Functions h and k are inverse functions, and both are defined for all real numbers using this relationship, what is the value of
mestny [16]

Answer:

(h o k)(3) = 3

(k o h)(-4b) = -4b

Step-by-step explanation:

If f(x) and g(x) are inverses, then (f o g)(x) = (g o f)(x) = x

(h o k)(3) = 3

(k o h)(-4b) = -4b
