Answer:

f(-1) is undefined.

Step-by-step explanation:

We are given:

$f(x) = \left\{ \begin{array}{ll} -3x-11 & \quad x \leq -5\\ 2 & \quad x > 5 \end{array} \right.$

And we want to find f(-1).

The piecewise function only gives us values for x-values less than or equal to -5 or greater than 5.

Since -1 is fits neither of those conditions, it is not defined.

Our answer is undefined.

Which sets of ordered pairs represent functions from A to B? (Select all that apply.) A = {a, b, c} and B = {3, 4, 5, 6}

sesenic [268]

Answer:

See Explanation

Step-by-step explanation:

The question has mission options; However, the question is still solvable.

Given

$A = \{a,b,c\}$

$B = \{3,4,5,6\}$

Required

Determine possible ordered pairs of A to B

A function is of the form (x,y)

Let A be the range of the function and B, the domain

Let (x,y) be a function of A to B, where x represents any of the values in A sets and y represents any of the values in B

A ordered pair can only be regarded as a function if and only if it has unique y-values

Hence, a possible ordered pair is:

$(A,B) = \{(a,3),(b,4),(c,5)\}$

Another possible ordered pair is

$(A,B) = \{(a,4),(b,5),(c,6)\}$

Note that there as as many as possible ordered pair as long as the y-values are unique

AngleB = Round your answer to the nearest hundredth. А 5 ? B С 4.

Zarrin [17]

Answer:

$B=36.87$

Step-by-step explanation:

As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.

Recall that $cos(B)=\frac{a}{h}$

This means that in order to find B, we need to take the inverse of cosine

This gives us

$B=cos^{-1} (\frac{4}{5} )$

From a calculator, we find that the answer of this is

$B=36.869$

When this is rounded to the nearest hundredth, we get

$B=36.87$
