Please help me on this question???

Step-by-step explanation:

Hey there!

According to the question;

Mass of an object (m) = 630 kg

Volume of an object (v) = 7m³

We know that;

[tex]density = \frac{mass(kg) \: }{volume( {m}^{3} )} [/tex]

or, density = (630/7) kg/m³

Therefore, density of the substance is 90kg/m².

Hope it helps!

Answer:

C) 140

Step-by-step explanation:

First find x by setting your formula up as

4x+20=5x-10

4x+20+10=5x

30=x

Now substitute 30 in place of x

Answer:

8800 is the amount before she buys her own instrument

Step-by-step explanation:

350 x 25 = 8750

8750 + 50 = 8800

Answer:

b

Step-by-step explanation:

this equation can be derived from the question :

95,000 - 250x = 75,000

where x is the equal amount of shares purchased for each client

given the amount of shares that remains after the shares has been purchased, we can determine the amount of shares bought by dividing the difference between 95,000 and 75,000 by 250

the price of each share was not made reference to in the question, thus it is not an important variable

Answer:

x = 0

Step-by-step explanation:

From the intersecting secants theorem, If from an exterior point, we draw two secant segments to a circle, then the product of the length of one secant segment and its external secant part will be equal to the product of the length of the other secant segment and its external secant portion.

Thus, applying it to this question;

(x + 27 + 48) × (x + 27) = (x + 45)²

(x + 75)(x + 27) = x² + 90x + 2025

x² + 102x + 2025 = x² + 90x + 2025

Like terms will cancel put to give;

102x - 90x = 0

12x = 0

x = 0/12

x = 0

Answer:

The correct answer is D. The financial analysis component of a business plan is to describe where the funds to start and operate your business will come from, when you expect to see profit, and how much profit you expect to see.

Step-by-step explanation:

Financial analysis is a type of economic analysis associated with the study of the financial results and financial condition of an organization.

Answer:

sqrt = square root of

Cosecant of 0 = (sqrt 41) / 5

Cos of 0 = 4/(sqrt41)

Tan of 0 = 5/4

Step-by-step explanation:

In this case, the opposite is 5, the adjacent is 4 and the hypotenuse is C in 5^2+4^2 = C^2 (pythagorean theorem)

5^2 = 25, 4^2 = 16

25+16 = 41

sqrt 41 is the hypotenuse

cosecant is hypotenuse/opposite

cos is adjacent/hypotenuse

and

tan is opposite/adjacent

[tex]2x^2 - 4x - 240 = 2(x + 10) (x - 12)[/tex]

Step-by-step explanation:

Given

[tex]1.\ x^4 - 1[/tex]

[tex]2.\ 2x^2 - 4x - 240[/tex]

Required

Factor

[tex]1.\ x^4 - 1[/tex]

Express as difference of two squares

[tex]x^4 - 1 = (x^2 - 1)(x^2 + 1)[/tex]

Express [tex]x^2 - 1[/tex] as difference of two squares

[tex]x^4 - 1 = (x- 1)(x + 1)(x^2 + 1)[/tex]

[tex]2.\ 2x^2 - 4x - 240[/tex]

Expand

[tex]2x^2 - 4x - 240 = 2x^2 -24x + 20x - 240[/tex]

Factorize

[tex]2x^2 - 4x - 240 = 2x(x -12) + 20(x - 12)[/tex]

Factor out x - 12

[tex]2x^2 - 4x - 240 = (2x + 20) (x - 12)[/tex]

Factor out 2

[tex]2x^2 - 4x - 240 = 2(x + 10) (x - 12)[/tex]

Answer:

We want to find the first 3 terms of the Taylor's series expansion for f(x) = sin(x) around x = 0.

Remember that a Taylor's series expansion of a function f(x) around the point x₀ is given by:

[tex]f(x) = f(x_0) + \frac{1}{2!}f'(x_0)*(x - x_0) + \frac{1}{3!}*f''(x_0)*(x - x0)^2 + ...[/tex]

Where in the formula we have the first 3 terms of the expansion (but there are a lot more).

So, if:

f(x) = sin(x)

x₀ = 0

The terms are:

[tex]f(x_0) = sin(0) = 0[/tex]

[tex]\frac{1}{2!}*f(x_0)'*(x - x_0) = \frac{1}{2} cos(0)*(x - 0) = x/2[/tex]

[tex]\frac{1}{3!}*f(x_0)''*(x - x_0)^2 = \frac{1}{6}*-sin(0)*(x - 0)^2 = 0[/tex]

[tex]\frac{1}{4!}*f(x_0)'''*(x - x_0)^3 = \frac{1}{24}*-cos(0)*(x- 0)^3 = -\frac{x^3}{24}[/tex]

We already can see that the next term is zero (because when we derive the cos part, we will get a sin() that is zero when evaluated in x = 0), then the next non zero term is:

[tex]\frac{1}{6!}*f(x_0)''''*(x - x_0)^5 = \frac{1}{2*3*4*5*6} *(x - 0)^5 = \frac{x^5}{720}[/tex]

Then we can write:

[tex]sin(x) = \frac{x}{2} - \frac{x^3}{24} + \frac{x^5}{720}[/tex]

Evaluating this in x = 0.2, we get:

[tex]sin(0.2) = \frac{0.2}{2} - \frac{0.2^3}{24} + \frac{0.2^5}{720} = 0.099667[/tex]

Solution :

Let, the equation on the line representing the given situation is :

y = mx + c

Here, m is the slope and c is the y-intercept .

Putting, ( 3, 2450 ) in above equation, we get :

2450 = m(3) + c

3m + c = 2450   ...1 )

Also, putting ( 7, 3050 ) in above equation, we get :

3050 = m(7) + c

7m + c = 3050   ...2)

Solving equation 1) and 2) , we get :

4m = 600

m = 150 and c = 2000

So, equation of line will be :

y = 150x  + 2000

A.)

Putting, x = 11 in above equation, we get :

y = ( 150 × 11 ) + 2000

y = $3650

B)

4100 = 150x + 2000

150x = 1100

x = 7.33

Since,  number of appliances sold cannot be in decimals.

So, x = 7

Hence, this is the required solution.
