Answer:
slope =6/4
Step-by-step explanation:
you jave to do rise over run,start at the y value which is where the graph of the line goes through the y axis then go up until you see a perfect point now go left or right depending on if it's a positive or negative slope.this is a positive slope so go right until you get to that perfect point
Answer:
A(t) = 676π(t+1)
Correct question:
A rain drop hitting a lake makes a circular ripple. Suppose the radius, in inches, grows as a function of time in minutes according to r(t)=26√(t+1), and answer the following questions. Find a function, A(t), for the area of the ripple as a function of time.
Step-by-step explanation:
The area of a circle is expressed as;
A = πr^2
Where, A = Area
r = radius
From the case above.
The radius of the ripple is a function of time
r = r(t) = 26√(t+1)
So,
A(t) = π[r(t)]^2
Substituting r(t),
A(t) = π(26√(t+1))^2
A(t) = π(676(t+1))
A(t) = 676π(t+1)
Answer:
y = 2x + 3
Step-by-step explanation:
the same slope would be 2x still
the 3rd and 4th choice are the only ones that have the correct slope
and 1 unit lower than 4 is 3
