: Discuss the continuity of the function f(x)=xtan(1/x) at x = 0 given that x≠0 and f(0)=0.

Answers

Answer 1

Answer:

Left hand Limit = Right Hand Limit = f(a)

it is a continuous function.

Step-by-step explanation:

Solution:

In order to find out the continuity of the function, we need to keep in mind following things:

Left hand Limit = Right Hand Limit = f(a)

Where, f(x) = exists and f(a) = defined.

Data Given:

f(x) = x tan(1/x)   x [tex]\neq[/tex] 0 (this function is used when x > 0  and x<0)

f(x) = 0 when x = 0

First we have to check the Left hand Limit.

L.H.L = f(0-h) (x<0)

Lim[tex]_{x-->0^{-} }[/tex] f(x)

Lim[tex]_{x-->0^{-} }[/tex] x tan (1/x)

Put x = 0-h

Lim[tex]_{x-->0^{-} }[/tex] (0-h) tan (1/(0-h))

Lim[tex]_{x-->0^{-} }[/tex]  h tan (1/h)

Putting h = 0

(0) x  (tan(1/0)))

As we know, for tanx value is a finitely oscillatory between -∞ to +∞  

Hence, 0 x finite number then,

L.H.L = 0

Similarly,

R.H.L = f(0+h)

Lim[tex]_{x-->0^{+} }[/tex] (0+h) tan (1/(0+h))

Lim[tex]_{x-->0^{+} }[/tex] (h) tan (1/(h))

R.H.L = 0

Now, as we know, when x = 0

f(x) = 0

f(0) = 0

Left hand Limit = Right Hand Limit = f(a)

Hence, it is a continuous function.

Make the following statement an equations (3,-3) m=3

Answers

Answer:

We conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:

[tex]y=3x-12[/tex]

The graph of the line is also attached.

Step-by-step explanation:

Given

The point (3,-3)The slope m = 3

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line (x₁, y₁) is the point

substituting the values m = 3 and the point (x₁, y₁) = (3,-3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-3\right)=3\left(x-3\right)[/tex]

Apply rule: -(-a) = a

[tex]y+3=3\left(x-3\right)[/tex]

subtract 3 from both sides

[tex]y+3-3=3\left(x-3\right)-3[/tex]

simplify

[tex]y=3x-12[/tex]

Therefore, we conclude that the line of equation containing the point (3, -3) with the slope m =3 will be:

[tex]y=3x-12[/tex]

The graph of the line is also attached.

At the beginning of the year Monica puts a set amount of money into her health benefit account. Every month she withdraws $15 from this account for her contact lenses. After 3 months she has $255 left in her account.


Write an equation in slope-intercept form to represent the relationship between the time that has passed and the amount of money left in Monica's account. Let x represent the time in months and y represent the amount of money remaining in the account.

Answers

Answer:

An equation in the slope-intercept form is:

[tex]y = 15x+210[/tex]

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where  m is the rate of change or slope and b is the y-intercept

Given

Let x represent the time in months Let y represent the amount of money remaining in the account.

Given that every month Monica withdraws $15 from this account for her contact lenses

so, the rate of change or slope = m = 15

Given that after 3 months she has $255 left in her account.

i.e. (3, 255)

substituting [tex]m = 15[/tex], [tex]x = 3[/tex] and [tex]y = 255[/tex] in the slope-intercept form to determine the y-intercept

[tex]y = mx+b[/tex]

[tex]255 = 15(3) + b[/tex]

switch sides

[tex]15(3) + b = 255[/tex]

[tex]45 + b = 255[/tex]

[tex]b = 255 - 45[/tex]

[tex]b = 210[/tex]

Thus, the y-intercept b = 210

Now, substituting [tex]m = 15[/tex] and [tex]b = 210[/tex] in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y = 15x+210[/tex]

Hence, an equation in the slope-intercept form is:

[tex]y = 15x+210[/tex]

How many 1/3 inch cubes does it take to fill a box with width 2 213 inches, length 3 1/3
inches, and height 2 1/3 inches?

Answers

Answer:

560 cubes

Step-by-step explanation:

Is 2 213 supposed to read 2 1/3? First calculate the volume of the box

V_box = 8/3 * 10/3 * 7/3 = 560/27 cubic inches

Now calculate the volume of your 1/3 inch cube:

V_cube = 1/3 * 1/3 * 1/3 = 1/27 cubic inches

Now divide the V_box by V_cube:

Number of boxes = (560/27) / (1/27) = (560/27) * (27/1) = 560 cubes

Answers

Answer:

-1/2

Step-by-step explanation:

In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.

If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.

The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:

incorrectly calculates the unit price as $13.92 per pair for the expense report What is the correct unit
price? What is the error?
The correct unit price is $ per pair

Answers

Answer:

The correct unit price is $1.16 per pair.

The contractor calculated the unit price in terms of per dozen.

Step-by-step explanation:

Given that:

Cost of 5 dozen pairs = $69.60

Unit price per dozen = [tex]\frac{69.60}{5} =\$13.92[/tex]

Unit price means the price of one pair of padded work gloves, so we will convert dozens into unit.

1 dozen = 12 pairs

5 dozen = 60 pairs

Unit price = [tex]\frac{69.60}{60}[/tex]

Unit price = $1.16 per pair

Hence,

The correct unit price is $1.16 per pair.

The contractor calculated the unit price in terms of per dozen.

Answers

Answer:

Slope of XZ = -5/9

Slope of YZ  = 2/7

Slope of XY  = -7/2

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

For XZ

X(−5, 5), and Z(4, 0)

Slope of XZ = 0-5/4-(-5)

Slope of XZ = -5/4+5

Slope of XZ = -5/9

For YZ

Y(−3, −2), and Z(4, 0).

Slope of YZ = 0-(-2)/4-(-3)

Slope of YZ = 2/4+3

Slope of YZ  = 2/7

For XY

X(−5, 5), Y(−3, −2)

Slope of XY = -2-5/-3-(-5)

Slope of XY = -7/-3+5

Slope of XY = -7/2

For two lines to be perpendicular, the product of their slope must be -1

Taking the product of XY and YZ

mXY * mYZ = -7/2 * 2/7

mXY * mYZ  = -1

since the product of mXY and mYZ is -1. this shows that line XY is perpendicular to YZ and showing that the triangle XYZ is right triangle
