Answer:
15 x^8 y^3
Step-by-step explanation:
The area of a rectangle is given by
A = l*w  where l is the length and w is the width
A = ( 5x^6 y^2) *( 3x^2 y)
    = 15 x^(6+2) y^(2+1)
    = 15 x^8 y^3
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
-The locust population grows by a factor and can therefore be modeled by an exponential function of the form:

Where:
 is the population after t days. is the population after t days.
 is the initial population given as 7600 is the initial population given as 7600
 is the rate of growth is the rate of growth
 is time in days is time in days
-Given that the growth is by a factor of 5( equivalent to 500%), the r value will be 5
-The population increases by a factor of 5 every 22 days. therefore at any time instance, t will be divided by 22 to get the effective time for calculations.
Hence, the exponential growth function will be expressed as:

 
        
             
        
        
        
Answer:
D
Step-by-step explanation:
The fourth graph makes sense, and follows Deepak's equation. To check if a graph follows an equation, all you have to do is substitute the values of x and y into the equation and see if they follow the equation.
 
        
                    
             
        
        
        
<span>1x + 2x = 15
3x = 15
3x/3 = 15/3
x = 5
Gemma = 1x, Zak = 2x therefore Gemma = 5 and Zak = 10</span>
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
The correct answer is C, -1. This is because slope formula is y2-y1/x2-x1. When you put that in you get 3-7/2-(-2) which equals -4/4, or -1.
