A 16" × 16" square tray can hold at most 9 bagels placed side by side, as shown below. At most how many bagels can a 32" × 32" s
vodka [1.7K]

Answer:

At most it can hold 18 bagels

Step-by-step explanation:

So we can make this an equation

16 · 16 square tray = 9 bagels on top of it

We just doubled both sides of it

giving us 32 · 32 square tray = 18 bagels can be held.

Chose parameters h and k such that the system has a) a unique solution, b) many solutions, and c) no solution. X1 + 3x2 = 4 2x1
AysviL [449]

Answer:

a) The system has a unique solution for k\neq 6 and any value of h, and we say the system is consisted

b) The system has infinite solutions for k=6 and h=8

c) The system has no solution for k=6 and h\neq 8

Step-by-step explanation:

Since we need to base the solutions of the system on one of the independent terms (h), the determinant method is not suitable and therefore we use the Gauss elimination method.

The first step is to write our system in the augmented matrix form:

\left[\begin{array}{cc|c}1&3&4\\2&k&h\end{array}\right]

The we can use the transformation r_0\rightarrow r_0 -2r_1, obtaining:

\left[\begin{array}{cc|c}1&3&4\\0&k-6&h-8\end{array}\right].

Now we can start the analysis:

  • If k\neq 6 then, the system has a unique solution for any value of k, meaning that the last row will transform back to the equation as:

(k-6)x_2=h-8\\x_2=h-8/(k-6)

from where we can see that only in the case of k=6 the value of x_2 can not be determined.

  • if k=6 and h=8 the system has infinite solutions: this is very simple to see by substituting these values in the equation resulting from the last row:

(k-6)x_2=h-8\\0=0 which means that the second equation is a linear combination of the first one. Therefore, we can solve the first equation to get x_1 as a function of x_2 o viceversa. Thus,  x_2 (x_1) is called a parameter since there are no constraints on what values they can take on.

if k=6 and h\neq 8 the system has no solution. Again by substituting in the equation resulting from the last row:

(k-6)x_2=h-8\\0=h-8 which is false for all values of h\neq 8 and since we have something that is not possible (0\neq h-8,\ \forall \ h\neq 8) the system has no solution
