Answer:

The y-intercept is 4

Step-by-step explanation:

You find the y-intercept by finding where x is zero. In the table, when x=0 the y=4. The y-intercept is 4. The graph of the function crosses the x-axis at the point (0,4).

Find K by evaluating Limit
Lubov Fominskaja [6]

Answer:

4

Step-by-step explanation:

\lim_{x \to \infty}\frac{1-cos4x}{1-cos2x}= \lim_{x \to 0} \frac{(1-cos4x)'}{(1-cos2x)'}= \lim_{x \to 0}\frac{4sin4x}{2sin2x}= \lim_{x \to 0}\frac{2*2sin2xcos2x}{sin2x}\\ = \lim_{x \to 0}4cos2x\\ =4

explain why a graph that fails the vertical-line test does not represent a function. Be sure to use the definition of a function
miss Akunina [59]
A function is defined as a relation in which  each element of a given set (the domain of the function) is associated with an element of another set ( the range of the function).

Note that it is ' an element' in the second set  NOT more than one element.

If a graph fails the vertical line test ( the line passes through the graph more than once) it means that there is more than one element in the range  associated with the element in the domain - so it is not a function.

What percent of 29 is 3?
Dominik [7]
You can put this in proportion form. 29 is the whole, so you would have 29 / 100. 3 is only part of it, and you want to know what is the percent for 3, so you would have 3 / x (Or any other variable is fine.)

29 / 100 = 3 / x

Cross multiply and you would get 29x = 300. Divide 300 by 29, and you would get the answer, which is 10.35. The answer would be x = 10.35.

What is the area of the figure below?
fgiga [73]

Answer:

Option a 26 inches square

Step-by-step explanation:

Given in the picture is a triangle with 3 sides as 10.8 inches, 5 inches and base =10+3 = 13 inches

The altitude for base 13 inches is shown as 4 inches.

We know that for any triangle area

=1/2 * base * height

Here base = 13 and height = 4

Hence area = 1/2 (13)(4) = 26 inches square

Answer is option a

---

This can be done in another way also

There are two triangles one with base 10 inches and height 3 inches and another with base 3 inches and height 4 inches

Area of combined figure = sum of area of two triangles

= 1/2 (10)(4) +1/2(3)(4) =

20+6

=26 square inches
