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>
Yes because the unit rate would be 1:2 and that's the rate of change in which 3:5 has.
HOPE IT HELPS!!
Question 1 might be B. 0.3
Question 2 might be D.TW, TM, CW, CM, HW, HM
I'm not 100% sure though
Answer:
c) 28
explanation :
In this sequence:
a1 = 2
a2 = 4
a3 = 6
a4 = 8
a5 = 10
and so on...
then
the sum from a2 to a5 is:
a2 +a3 + a4 + a5 = 4 + 6 +8 + 10 = 28
