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>
Answer:
The width is 3 yds
Step-by-step explanation:
Area = length * width
18 = 6*w
Divide each side by 6
18/6 = 6w/6
3=w
The width is 3 yds
Answer:
7. b
8. a
Step-by-step explanation:
Part a:-
7.15 rands = 1 dollar
So we are going to MULTIPLY to find out how many rands there are going to be.
1000 × 7.15 = <span>7150
<span>So, 7150 rands is your answer.
Part b:-
To do this first we will DIVIDE.
6274 </span></span>÷ 7.15 ≈ <span>877.482.......
So, 6274 rands is ABOUT $878.
Par a:- 7150 rands
Part b:- about $878.
Hope I helped ya!!!!!</span>
