Answer: The amount of carbon-14 remaining after 4 years is 99.95 grams.
Step-by-step explanation:
Hi, to answer this question we simply have to substitute t=4 in the equation given and solve for c.
c= 100 (0.99988)^t
c =100 (0.99988)^4
c = 100 x 0.999520086
c= 99.95200864 ≅99.95 grams (rounded)
The amount of carbon-14 remaining after 4 years is 99.95 grams.

Rotation and reflection are instances of transformation
See attachment for the new position of  
From the question, we have:


The rule of 90 degrees clockwise rotation is:

Using the above transformation, the new points would be



The next transformation is reflection over the x-axis
The rule of this transformation is:

So, the new points would be:

Answer:
a
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint 
b
The number is  
c
The price is 
Step-by-step explanation:
From the question we are told that 
    The ratio of  the number of cups of blue paint to the number of cups of red paint is  
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint 
Given that  1 cup of  red paint  =>   3 cups of blue paint 
                  x cup of  red paint  =>  1  cup of  blue paint 
So 
          
=>      
Generally the unit price of a cup of blue paint is mathematically represented as 
      
 =>  
      
 
        
             
        
        
        
Answer:
B. 66.0
Step-by-step explanation:
The formula for circumference is 2*π*r where r is the radius. MS and MR are both radii, so we can plug in 10.5 to the formula to get 2* π*10.5, which would be about 65.97, which rounds to 66.0. Hope this helps!
