Answer:
d So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered
Step-by-step explanation:
When we have an equation of the form
y = ab^x
a is the initial value at time x=0
b is the growth (or decay ) factor
and x is the time
So y = 10 (.5)^x the 10 is the initial amount of the sample at the time it was discovered
Answer:
its the last one tell me if im right
Step-by-step explanation:
Answer:
y = 3x -4
Step-by-step explanation:
point slope form:
y - y1 = m(x-x1)
y-(-5) = 3(x-(-3))
y+5 = 3x + 9
y = 3x -4
To find the length of a line between two points with known x- and y- coordinates, use:
sqrt((change in x)^2 + (change in y)^2),
which I know may look confusing but it isn't really:
sqrt((5 - -3)^2 + (4 - -1)^2)
= sqrt(8^2 + 5^2)
= sqrt(64 + 25)
= sqrt(89)
A point of any shape or polygon is called a vertex
