Answer 2

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

What is the arctan function?

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.

yogurt?

Answers

9514 1404 393

Answer:

  95%

Step-by-step explanation:

The given limits differ from the mean by ...

  1.30 -1.50 = -0.20

  1.70 -1.50 = 0.20

These values are 2 × the standard deviation of 0.10. The 68-95-99.7 rule tells you that 95% of the population lies within 2 standard deviations of the mean.

For this question, that means 95% of customers are willing to pay between $1.30 and $1.70.

Use the given conditions to write an equation for the line in point-slope form and general form.
Passing through (-7,9) and parallel to the line whose equation is 7x - 4y - 9 = 0
The equation of the line in point-slone form is

Answers

Answer:

(y - 9) = 7/4(x + 7)

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope slopes.

The first line is 7x - 4y - 9 = 0.

First let's convert this to y = mx + b form.

7x - 4y - 9 = 0

Add 4y to both sides.

7x - 9 = 4y

Divide each term by 4.

y = 7/4x - 9/4

The slope is 7/4. A line parallel to this one will also have a slope of 7/4.

The standard point-slope form is:

(y - y₁) = m(x - x₁)

For the point-slope form, you need two things: a point and a slope.

point: (-7, 9)slope: 7/4.

Plug in our given information.

(y - 9) = 7/4(x - (-7))

Simplify.

(y - 9) = 7/4(x + 7)

Learn with another example.

Hope this helps!

Let's consider the information given:

line passes through (-7,9)line is parallel to 7x - 4y - 9 = 0

What do we want to solve: put the equation of the line in point-slope form

 ⇒ point-slope form ⇒ [tex]y-y_{0}=m(x-x_{0} )[/tex]

[tex](x_{0} ,y_{0} )[/tex] : any point on the linem: slope

 Find the slope of 7x - 4y = 9

              ⇒ first put it into slope-intercept form [tex]y = mx +b[/tex]

                         -where m is the slope and b is the y-intercept

                                 [tex]7x-4y-9=0\\7x-4y=9\\-4y=-7x+9\\y=\frac{7}{4}x-\frac{9}{4}[/tex]

               ⇒ Slope is 7/4

     2. When two lines are parallel, their two slopes are equal, and since

         the line passes through (-7,9), use point-slope form

                [tex]y-9=\frac{7}{4}(x+7)[/tex] <== point-slope form

What do we also want: find the general form ⇒ Ax + By = C

A: coefficient of xB: coefficient of yC: constant

To find the general form, move all the variables to one side and the  constant to the other, using the point-slope form

               [tex]y-9=\frac{7}{4}(x+7)\\ y-9=\frac{7}{4}x+\frac{49}{4} \\-\frac{7}{4}x+y=9+\frac{49}{4} =\frac{36}{4} +\frac{49}{4} =\frac{85}{4} \\-\frac{7}{4}x+y=\frac{85}{4}[/tex]<== general form

A. 62.83 units
B. 157.08 units
C. 314.15 units
D. 31.42 units

Answers

Answer:

A

Step-by-step explanation:

that means the radius of the left and right circles is 2 units.

and the height of the cylinder is 5 units.

the volume of a cylinder is calculated by first standing it upright on one of the circles, and then the volume is ground area times height.

the area of a circle is pi×r².

so the volume here for us is then

pi×2²×5 units = pi×4×5 = pi×20 = 62.83185307... units

and that makes A the correct answer.

Answers

Answer:

32%

Step-by-step explanation:

too lazy to type it out.

Answer:

32%.

Step-by-step explanation:

Value in 2019 = 800 + 10% of 800

= 800 + 0.1*800

=  $880.

In 2020 , value

=  880 + 0.2*880

Increase in value over 2 years = 1056 - 800 = $256.

% increase = 100 * 256/800

My father’s monthly salary is twice what my mother makes in a month. Their combined salary is P27,000


Please help !

Answers

Step-by-step explanation:

mother salary: x

father salary:2x

total salary =27000

therefore 3x=27000

so x=900 (divided by 3)

therefore mother salary = 900

father salary=2multiplied by 900=1800

Answer:

Father's monthly salary is P18,000

Mother's monthly salary is P9,000

Step-by-step explanation:

The problem above can be solved by using "algebraic expressions."

Let x be the father's monthly salary

Let y be mother's monthly salary

Formula: x + y = P27,000

If father's monthly salary is twice than what mother makes, then: x = 2y, which means,

2y (father's salary) + y (mother's salary) = P27,000

First step: 2y + y = P27,000

Second step: 3y = P27,000

Third step: y = [tex]\frac{P27,000}{3}[/tex]

Fourth step: y = P9,000

So, mother's salary is P9,000. This means we can get father's salary:

2y = 2 × P9,000 = P18,000 (this is the value of x)

So, father's salary is P18,000.

If we combine both of their salaries, the product is P27,000.

x + y = P27,000

P18,000 + P9,000 = P27,000

So, this explains the answer.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

Let x be the total number of miles:

From the question:

y be the total cost of hiring

y = 20 + 2x

y = 170

170 = 20 + 2x

150 = 2x

x = 150/2

x = 75 miles

Thus, the number of miles is 75 miles if the vehicle hire firm charges $20 as a flat fee for renting a vehicle plus $2 per mile.

what is the slope of a line parallel 18x+15y=90

Answers

Answer:

-6/5

Step-by-step explanation:

Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.

Answer:

[tex]\displaystyle -1\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]\displaystyle 18x + 15y = 90 \hookrightarrow \frac{15y}{15} = \frac{-18x + 90}{15} \\ \\ \boxed{y = -1\frac{1}{5}x + 6}[/tex]
