Which of the two solids below are similar ?
Pachacha [2.7K]

Answer:  I and II.

Step-by-step explanation:

By definition, two solids are similar if their corresponding sides are in the same ratio.

Knowing this, let's find which solids are similar:

Corresponding sides ratio of solids I and II:

\frac{3}{2}=\frac{2}{\frac{4}{3}}=\frac{5}{\frac{10}{3}}

\frac{3}{2}=\frac{3}{2}=\frac{3}{2}

Corresponding sides ratio of solids I and III:

\frac{3}{\frac{9}{2}}=\frac{2}{3}=\frac{5}{8}

\frac{2}{3}=\frac{2}{3}=\frac{5}{8}

Corresponding sides ratio of solids II and III:

\frac{2}{\frac{9}{2}}=\frac{\frac{4}{3}}{3}}=\frac{\frac{10}{3}}{8}}

\frac{4}{9}=\frac{4}{9}=\frac{5}{12}

 You can observe that the solids  I and II are similar.

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.

If a scalene triangle has its measures 4 m, 11 m and 8 m, find the largest angle.
soldier1979 [14.2K]

Answer:

129.8 approximately

Step-by-step explanation:

So this sounds like a problem for the Law of Cosines. The largest angle is always opposite the largest side in a triangle.

So 11 is the largest side so the angle opposite to it is what we are trying to find. Let's call that angle, X.

My math is case sensitive.

X is the angle opposite to the side x.

Law of cosines formula is:

x^2=a^2+b^2-2ab \cos(X)

So we are looking for X.

We know x=11, a=4, and b=8 (it didn't matter if you called b=4 and a=8).

11^2=4^2+8^2-2(4)(8)\cos(X)

121=16+64-64\cos(X)

121=80-64\cos(X)

Subtract 80 on both sides:

121-80=-64\cos(X)

41=-64\cos(X)

Divide both sides by -64:

\frac{41}{-64}=\cos(X)

Now do the inverse of cosine of both sides or just arccos( )

[these are same thing]

\arccos(\frac{-41}{64})=X

Time for the calculator:

X=129.8 approximately
