Answer:
Option (1)
Step-by-step explanation:
We need a recursive formula.
The common ratio is 2.
- Eliminate options 2 and 4.
So, the answer is option 1.
 
        
             
        
        
        
Given:
The expression is  .
.
To find:
The shows the correct way to use the rule ""multiply by the reciprocal"" for the given expression.
Solution:
According to the rule "multiply by the reciprocal", if a,b,c,d are four number, then

We have,

It can be written as

Using the rule "multiply by the reciprocal", we get



Therefore, the correct option is D.

Answer:
   d.  45
Step-by-step explanation:
You can check the offered answers. You will find that the difference from reversing the digits will only be 9 if the digits differ by 9/9 = 1. 
The original number is 45.
__
<em>Check</em>
   45 + 9 = 54 . . . with the digits reversed
 
        
             
        
        
        
Answer:
   1,778
Step-by-step explanation:
Let C and S represent the cost and salvage value of Truck B, respectively. Let X represent the number of miles per year that answers the question.
Truck A's cost for 10 years is ...
   A = C+600 +(0.06)(2.25)(10X) -(S+200)
Truck B's cost for 10 years is ...
   B = C +(0.07)(2.25)(10X) -S
We want to find X such that Truck A's cost is lower, so ...
   C -S +1.35X +400 < C -S +1.575X
   400 < 0.225X
   1777 7/9 < X
1778 miles driven per year (or more) makes Truck A a better option.
 
        
             
        
        
        
Here, Given
h= 8ft
a=144 * ft^2
then,
A=L*H
144=L*8 or 144/8 =L
L=18
now, P=2(L+H)
P=2(18+8)
P=52m
Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.
The perimeter of a 2D shape is the distance around the shape. You can imagine wrapping a string around a triangle. The length of this cord is around the triangle. Or, if you're traveling outside the park, take a route that goes around the edge of the park.
