So let's get k on one side:
2k = 2
Divide by 2:
k = 1

If you want to check your work:
1 + 1 = 3 - 1
2 = 2

Use the graph of the function f to determine the given limit. Picture below

Oduvanchick [21]

Answer:

Option: a is correct.

Limit of the function at x=2 is: 2

Step-by-step explanation:

Clearly by looking at the graph of the function we could observe that the function f(x) is defined as:

f(x)= -x+4 when x≠4

and 8 when x=2

since we could see that the function f(x) is a line segment that passes through the point (4,0) and (0,4).

and the equation of line passing through two points (a,b) and (c,d) is given by:

$y-b=\dfrac{d-b}{c-a}\times (x-a)$

Here a,b)=(4,0) and (c,d)=(0,4)

Hence,

the equation of line is:

$y-0=\dfrac{4-0}{0-4}\times (x-4)\\\\y=\dfrac{4}{-4}\tmes (x-4)\\\\y=-1(x-4)\\\\y=-x+4$

Now the left hand limit of the function at x=2 is:

$\lim_{h \to 0} f(2-h)\\\\= \lim_{h \to 0} -(2-h)+4\\ \\=\lim_{h \to 0} -2+h+4\\\\=\lim_{h \to 0}2+h\\\\=2$

Similarly the right hand limit of the function at x=2 is:

$\lim_{h \to 0} f(2+h)\\\\= \lim_{h \to 0} -(2+h)+4\\ \\=\lim_{h \to 0} -2-h+4\\\\=\lim_{h \to 0}2-h\\\\=2$

Hence, the limit of the function at x=2 is:

Jasmine has taken an online boating safety course and is now completing her end-of-course exam. As she answers each question, th

dsp73

Answer:

There are 60 total questions on the course exam.

Step-by-step explanation:

Given that:

Number of questions finished by Jasmine = 12

Percentage shown on the bar = 20%

The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

Let,

x be the total number of questions on the course exam

20% of x = 12

$\frac{20}{100}x=12\\0.2x=12$

Dividing both sides by 0.2

$\frac{0.2x}{0.2}=\frac{12}{0.2}\\x=60$

Hence,

There are 60 total questions on the course exam.
