Answer:
1. 8
2. -1/2
i dont know how to do the other problems, but i did know how to solve the 1st 2 questions. hope it helped :)
Step-by-step explanation:
Answer:
let's use c as circumference, d for diameter
lets say c increases, d is related to c, d will also increase
if c decreases, d will too.
Let's put in this way.
Pretend you're at a store,
The more you spend, the more points you get in their loyalty program
C is going to be the amount you spend
D will be how many points you get
Spend more, more points
spend less, less points
P.S
C is the independent variable, D is the dependent variable. (I think that's the right way, if not ignore the postscript aka P.S)
a. The gradient is
b. The gradient at point P(1, 2) is
c. The derivative of at P in the direction of is
It looks like
so that
Then
4,3,6,1
(a) multiple of 5 : 4(3 + 6 + 1) = 4(10) = 40
(b) factor of 36 : (4)(3) + (6)(1) = 12 + 6 = 18
