Answer:

B (there is a negative correlation)

Step-by-step explanation:

Complete the square and give a substitution (not necessarily trigonometric) which could be used to compute the integral. ∫1x2+2x

Ugo [173]

Answer:

Substitution of x+1

Step-by-step explanation:

We are given that

$\int \frac{1}{x^2+2x+2}dx$

$\int\frac{1}{(x^2+2x+1)+1}dx$

$\int\frac{1}{(x+1)^2+1^2}dx$

By using identity

$(a+b)^2=a^2+b^2+2ab$

Substitute x+1=t

Differentiate w.r.t x

dx=dt

Substitute the values

$\int\frac{1}{t^2+1^2}dx$

$\frac{1}{1}tan^{-1}\frac{t}{1}+C$

By using formula : $\int\frac{1}{x^2+a^2}dx=\frac{1}{a}tan^{-1}\frac{x}{a}+C$

$tan^{-1}(x+1)+C$

A candy shop sells a box of chocolates for $30. It has $29 worth of chocolates plus $1 for the box. The box includes two kinds o

sergey [27]

Answer:

There are 3 lbs of candy in the box.

The caramels are $8 per pound.

12y represents the total cost of truffles in the box.

8x + 12y + 1 represents the cost of caramels in the box + the cost of truffles in the box + the cost of the box.

Step-by-step explanation:

x = the number of pounds of caramels

y = the number of pounds of truffles

x + y = total lbs. and we know x + y = 3

We know x is the number of pounds of caramels.

8x = (cost per pound of caramels) × (number of pounds of caramels)

So 8 = cost of caramels

We know y = number of pounds of truffles. So 12 is the cost of truffles by pound, and 12y is the total cost of truffles in the box.

Based on all the above,

The cost of caramels in the box + the cost of truffles in the box + the cost of the box is = total cost of the box. 8x + 12y + 1 = 30
