Figure 1 shows the curve = ! and a point (−1,0). The point (, 0) is a variable point on the axis and increases at a rate of 10 units "#. The line is parallel to the axis.
a) Express the area of PQR in terms of .
b) Calculate the rate of change in the area when = 2.
c) Calculate the rate of change in the length when = 1.

Figure 1

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

i think it is 70

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
