Answer:
Step-by-step explanation:
x_0=0
x_1 = $40
so delta change is $40. Now we can write the equation as
y = 40x, where y is the total saving account amount.
So after the 6th deposit, her total saving is $240.
y = 40(6) => 240
Answer:
points (2,3) and (-2,9)
Step-by-step explanation:
5(0.85)t < 1.5 is 15% decay
50(1.05)t < 100 is 5% growth
150(1.50)t > 500 is 50% growth
50(1.15)t < 150 is 15% growth
Hello :
f'(7) = the slope of the tangent line : let A(7,4) B(0,3)<span>
<span>the slope is : (YB - YA)/(XB -XA)= (3-4)/(0-7) = -1/-7 = 1/7=f'(7)
the equation of the tangent line is :
y-3 = 1/7 (x-0)
y = (1/7)x+3
the line tangent and the graph of : f </span></span><span>passes through the point A(7, 4)
x= 7 y=4 so : f(7) =4</span>
