Is the function given by f(x)equalsleft brace Start 2 By 2 Matrix 1st Row 1st Column one fourth x plus 1 comma 2nd Column for x

MArishka [77]

Answer:

C. The given function is continuous at x=4 because the limit is 2.

Step-by-step explanation:

Given the function:

$f(x)=\left\{\begin{array}{ccc}\frac{1}{4}x+1 &x\leq 4\\4x-11&x>4\end{array}\right$

We are to determine if the function is continuous at x=4.

For a function to be continuous at some value c in its domain:

f(c) must be defined.

$Lim_{x \to c}$ f(x)$ must exist.

$f(c)=Lim_{x \to c}$ f(x)$

Now: at x=4

$f(4)=\dfrac{1}{4}*4+1=2$

$Lim_{x \to 4}f(x)=2$

Since the two values are the same, we say that f(x) is continuous at x=4.

The correct option is C.

60 is what percent of 72

tatuchka [14]

If you would like to solve 60 is what percent of 72, you can calculate this using the following steps:

60 is what percent of 72
60 = x% of 72
60 = x% * 72
60 = x/100 * 72
60/72 = x/100
x = 60/72 * 100
x = 83.33%

The correct result would be 83.33%.

What is the sum of the matrices below ?

Vanyuwa [196]

Answer:

$\left[\begin{array}{ccc}4&19&-5\\7&0&-14\end{array}\right] + \left[\begin{array}{ccc}-8&7&0\\-1&17&6\end{array}\right] = \left[\begin{array}{ccc}-4&26&-5\\6&17&-8\end{array}\right]$

Step-by-step explanation:

To add two matrices you just need to add the corresponding entries together. In this case, we have that:

$\left[\begin{array}{ccc}4&19&-5\\7&0&-14\end{array}\right] + \left[\begin{array}{ccc}-8&7&0\\-1&17&6\end{array}\right]=\left[\begin{array}{ccc}4-8&19+7&-5 + 0\\7-1&0+17&-14+6\end{array}\right] = \left[\begin{array}{ccc}-4&26&-5\\6&17&-8\end{array}\right]$

Then, we conclude that the sume of the two matrices is:

$\left[\begin{array}{ccc}4&19&-5\\7&0&-14\end{array}\right] + \left[\begin{array}{ccc}-8&7&0\\-1&17&6\end{array}\right] = \left[\begin{array}{ccc}-4&26&-5\\6&17&-8\end{array}\right]$

5/6-(2/3-4/9)= (5/6-2/3)-4 is this equal

Agata [3.3K]

This equation is False.

5/6-(2/3-4/9) = 11/18

(5/6-2/3)-4 = -23/6

Showing two different answers, so no they are not equal.
