Can someone help me with this real quick!

Answer:

D. The graph is symmetric about the origin.

Step-by-step explanation:

got it right on edge :)

The correct option is Option D: The graph is symmetric about origin.

The function f(x) = arctan x is the inverse of tangent function y=tanx.

Checking all the options

Option A: This option is incorrect as the domain of arctan x is real number R i.e. (-∞,∞). arctan x is valid for all values of x between -∞ to ∞.

Option B: This option is incorrect as the range of the function arctan x is (-π/2, π/2) which is the restricted domain of the tan x.

Option C: This option is incorrect as the graph is continuous in R and also bounded in (-π/2, π/2) so it has no vertical asymptotes. But tan x has vertical asymptotes.

Option D: This option is correct as from the graph it is also clear that this function arctan x is symmetric about the origin. Also, function arctan x is an odd function. As odd functions are symmetric about origin, arctan x is symmetric about the origin.

Therefore The correct option is Option D: The graph is symmetric about origin.

Answer:

A, .54

Step-by-step explanation:

The number line ranges from .542 up until .611, giving you three options below. For .6, it can be translated into .600 which is in bounds of the number line. Next for .604, it is still in bounds of the number line. For .54 it would be translated to .540 which is not in bounds, being before .542.

Answer:

8 + X

Step-by-step explanation:

Using Cos formula of a triangle

let BA be x

x² = a² + b² -2abCos(90°)

x² = 64 + 196

x = √260

To find <B using Cos again

b² = a² + c² - 2acCos(B)

196 = 64 + 260 - 2 * 8 * √260 * cosB

196=324 - 16√260 *cosB

324-196=16√260CosB

8 = √260CosB

CosB = 8/√260

B = cos-¹(8/(√260))

C.No,because he used the incorrect value for it.

Answer:

x=80

Step-by-step explanation:

This is really simple especially since you have a right triangle, you can easily determine x using trigonometry.

The cosine of an angle in a right triangle is defined by it's adjacent side divided by the hypotenuse.

[tex] \cos(50) = \frac{51}{x} [/tex]

The angle in question is 50, the hypotenuse is the side facing the 90° angle and the adjacent side is the one next to it.

By cross multiplication i can rewrite this as:

[tex]x = \frac{51}{ \cos(50) } [/tex]

[tex]x = \frac{51}{0.64278} [/tex]

[tex]x = 79.34[/tex]

Round to the nearest ten

[tex]x = 80[/tex]

Answer: No

Step-by-step explanation:

Cherries costs $5.68 per pound so to find the price of 4.1 pounds, multiply them both together.

$5.68 x 4.1 lb. = $23.3

It costs about $23.3 to purchase 4.1 pounds so you can not buy it with $20.

Answer:

The $20 estimate is too low. $5.68 was incorrectly rounded down; it should have been rounded up to $6. The correct estimate should have been $24, so $20 will not be enough to buy 4.1 pounds of cherries

Answer:

[tex]y=4.5t+20\\\\t=20\\y=4.5*20+20\\y=90+20\\y=110[/tex]

Step-by-step explanation:

So when t=0 in the first equation y=20 which is the length as you are just born. How I calculate 4.5 is that I assume:

y=xt+20

for t=10 we have y=65

65=10x+20

10x=45

x=4.5

the equation becomes y=4.5t+20.

Answer:

  4/7 = $7.04/x

Step-by-step explanation:

You can write the proportion 4 different ways. Any way you write it, you want markers in corresponding positions and prices in corresponding positions.

Here the best choice is ...

  (reference quantity)/(different quantity) = (reference price)/(different price)

  4/7 = $7.04/x

Additional comment

Many people might choose to put the unknown in the numerator:

  x/$7.04 = 7/4

or

  x/7 = $7.04/4

Answer:  None of the above

Step-by-step explanation:

The easiest way to get the cost is to get the cost per unit times the number needed.

x  = 7($7.04/4 )  To make that into a proportion it would look like

x/7 = $7.04/4

[tex]\frac{x}{7} =\frac{7.04}{4}[/tex]
