Base on my calculation and also by the sue of the data you give where as the triangle ABC is rotated by 100 counter clockwise about point P to create triangle A'B'C' the possible value of angle C'A'B is 70 degrees. I hope you are satisfied with my answer and feel free to ask for more

Answer:

d

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , then

$\frac{2^{12} }{2^{3} }$ = $2^{(12-3)}$ = $2^{9}$

Suppose customers in a hardware store are willing to buy N(p) boxes of nails at p dollars per box, as given by the following f

AleksAgata [21]

Answer:

a) -15 unites per dollar

b) -12 units per dollar

c) -18 units per dollar

Step-by-step explanation:

We are given the following in the question:

$N(p) = 100-3p^2, 1\leq p \leq 4$

where N(p) is the number of boxes of nails at p dollars per box.

a) average rate of change of demand for a change in price from $2 to $3.

Average rate of change =

$\displaystyle\frac{N(3) -N(2)}{3-2}\\\\=\frac{100-3(3)^2-(100 - 3(2)^2)}{1}\\\\= -15\text{ units per dollar}$

b) instantaneous rate of change of demand when the price is $2

Instantaneous rate =

$N'(p) = \displaystyle\frac{d(N(p))}{dp} = -6p$

$N'(2) = -6(2) = -12$

The instantaneous rate of change of demand when the price is $2 is decreasing at 12 units per dollar.

c) instantaneous rate of change of demand when the price is $3

Instantaneous rate =

$N'(3) = -6(8) = -18$

The instantaneous rate of change of demand when the price is $3 is decreasing at 18 units per dollar.
