The density d kg/m3 of a cube of mass m kilograms and side length x meters is given by the formula:  What is the value of d if m = 40 and x = 0.2?​

Answers

Answer 1

Answer:

5000kg/m3

Step-by-step explanation:

Its easy to get the answer of a question from the unit.

So, it will be mass over metre cube.

Therefore, m=40kg x= (0. 2)^3 =0. 008m

40/0. 008 = 5000kg/m^3

Answers

Answer:

A. 158

Step-by-step explanation:

Angle ABC and Angle ECF have the same tick mark(little line over the angle). The means they are congruent, the same. Since Angle ECF + Angle DCE = 180 degrees, 180 - 22 is the measure of angle DCE, or 158. You're welcome, and brainliest me.

A rectangle has a height of 3 cm and width of 5cm. A proportional rectangle has a height of 12cm. What would be the width?

Answers

Step-by-step explanation:

a proportional or similar shadow uses the same factor for each line/dimension.

so, since the height of the proportional rectangle is 4 times longer than the height of the original rectangle, then also the width must be 4 times longer.

heightP = 12 cm = f × height = f × 3 cm

f = 12/3 = 4

widthP = f × width = 4 × 5 = 20 cm

Integral of x"2+4/x"2+4x+3

Answers

I'm guessing you mean

[tex]\displaystyle \int\frac{x^2+4}{x^2+4x+3}\,\mathrm dx[/tex]

First, compute the quotient:

[tex]\displaystyle \frac{x^2+4}{x^2+4x+3} = 1 + \frac{4x-1}{x^2+4x+3}[/tex]

Split up the remainder term into partial fractions. Notice that

x ² + 4x + 3 = (x + 3) (x + 1)

Then

[tex]\displaystyle \frac{4x-1}{x^2+4x+3} = \frac a{x+3} + \frac b{x+1} \\\\ \implies 4x - 1 = a(x+1) + b(x+3) = (a+b)x + a+3b \\\\ \implies a+b=4 \text{ and }a+3b = -1 \\\\ \implies a=\frac{13}2\text{ and }b=-\frac52[/tex]

So the integral becomes

[tex]\displaystyle \int \left(1 + \frac{13}{2(x+3)} - \frac{5}{2(x+1)}\right) \,\mathrm dx = \boxed{x + \frac{13}2\ln|x+3| - \frac52 \ln|x+1| + C}[/tex]

We can simplify the result somewhat:

[tex]\displaystyle x + \frac{13}2\ln|x+3| - \frac52 \ln|x+1| + C \\\\ = x + \frac12 \left(13\ln|x+3| - 5\ln|x+1|\right) + C \\\\ = x + \frac12 \left(\ln\left|(x+3)^{13}\right| - \ln\left|(x+1)^5\right|\right) + C \\\\ = x + \frac12 \ln\left|\frac{(x+3)^{13}}{(x+1)^5}\right| + C \\\\ = \boxed{x + \ln\sqrt{\left|\frac{(x+3)^{13}}{(x+1)^5}\right|} + C}[/tex]

What is the difference?
2x+5 3x+ 5 X+ 1
x² – 3x X² – 9x x²-g

Answers

Answer:

(x + 5)(x + 2) / (x³ - 9x)

Step-by-step explanation:

We need to find a common denominator.

factor each denominator

x² - 3x = x(x - 3)

x³ - 9x = x(x² - 9) = x(x + 3)(x - 3)

x² - 9 = (x + 3)(x - 3)

As the factors of the first and third denominators are subsets of the second, the second is the LCD. This immediately eliminates the last two options as possible solutions.

Now we multiply each term by the missing factor over itself (1)

(2x + 5)(x + 3) - (3x + 5) - (x + 1)(x)]

(x² - 3x)(x + 3)   (x³ - 9x)  (x² - 9)(x)

[(2x² + 11x + 15) - (3x + 5) - (x² + x)] /  (x³ - 9x)

[2x² + 11x + 15 - 3x - 5 - x² - x] /  (x³ - 9x)

(x² + 7x + 10) /  (x³ - 9x)

(x + 5)(x + 2) / (x³ - 9x)

Suppose y varies inversely with x, and y = -1 when x = 6. What inverse variation equation relates x and y?

NO LINKS OR ANSWERING QUESTIONS YOU DON'T KNOW!!!
a. y = 6/x
b. y = -12x
c. y= -6x
d. y= -6/x​

Answers

Answer:

[tex]\displaystyle \text{d. }y=\frac{-6}{x}[/tex]

Step-by-step explanation:

If two values [tex]x[/tex] and [tex]y[/tex] are inversely proportional, their product is always some maintained constant (the product of [tex]x[/tex] and [tex]y[/tex] is always maintained). This way, if one goes up, the other must go down by the same extent. By definition, this represents an inversely proportional relationship.

Therefore, we can simply find this constant by multiplying the given values of [tex]x[/tex] and [tex]y[/tex]:

[tex]xy=k,\\6\cdot (-1)=-6[/tex]

The constant [tex]-6[/tex] must be maintained as the product of [tex]x[/tex] and [tex]y[/tex] for all values of [tex]x[/tex] and [tex]y[/tex] for them to be inversely proportional. Thus, we have the equation:

[tex]xy=-6[/tex]

Divide both sides by [tex]x[/tex] to isolate [tex]y[/tex]:

[tex]\boxed{y=\frac{-6}{x}}[/tex]

Answer:

d. [tex]\displaystyle y = \frac{-6}{x}[/tex]

What is the y-intercept of the graph of the equation ?

Answers

Tryna boost my score for college math could you give me the brainiest and a thanks? Hope you find your answer your looking for!

Answer:

Step-by-step explanation:

It is the point where the graph passes through the y-axis.

So if it passes through the point where y = 2,  the y-intercept is (0, 2) - note the x coordinate is 0 at this point.

If we are asked to find the y-intercept of the graph of the equation y = 3x - 4

we put  x = 0 and work out y as follows:

y = 3(0) - 4 = 0 - 4

y = -4

so the y-intercept is (0, -4).

in filing his income​ tax, raul reported annual contributions of ​$350 350 to a public radio​ station, ​$210 210 to a public tv​ station, ​$100 100 to a local food​ bank, and ​$294 294 to other charitable organizations what's the monthly expense?

Answers

Answer:

$79.50

Step-by-step explanation:

1. $350 + $210 + $100 + $294 = $954

2. $954 ÷ 12 = 79.50

Raul monthly expense is $79.50.

Here,

In filing his income​ tax, Raul reported annual contributions of ​$350 350 to a public radio​ station, ​$210 210 to a public tv​ station, ​$100 100 to a local food​ bank, and ​$294 294 to other charitable organizations.

We have to find Raul's monthly expense.

What is total amount?

A total is a whole or complete amount.

Now,

Raul's annual expense = $350 + $210 + $100 + $294

                                   = $954

Hence,

Raul's monthly expense =  954/12

                                     = 79.50

So, Raul monthly expense is $79.50.
