Answer:
The fossil is 1860 years old.
Step-by-step explanation:
The equation for the amount of fossil has the following format:
In which Q(t) is the amount after t years, Q(0) is the initial amount and r is the rate of change.
Half-life of c-14 is 5730 years.
This means that 
So
So
How old is the fossil?
This is t for which
So
The fossil is 1860 years old.
We start with the equation y-y1 =m (x-x1) because we have m the slope = 1/4 and a point on the line with the coordinates (x1=-20, y1=-6) so,
y+6=1/4 ( x+20);
y=(1/4)x + 20/4 -6;
y= (1/4)x -1 and this is the equation in slope intercept form y=mx +b where the lope m= 1/4 and b= -1 the y-intercept
Answer <span>y= (1/4)x -1 </span>
Answer:
217miles is how far he travels
Step-by-step explanation:
I did 62mph * 3 1/2 and got 217.
I'm unsure if this is correct but I tried my best in solving this!
Answer:
Angle A = 53
Step-by-step explanation:
All triangles add up to 180 so...
Lets use x to describe angle A
100+27+x=180
127+x=180
x=53
I'm confused what its asking about b and c but hope this helps a bit :)
