What is the total area of the regions between the curves y = 6x2 − 18x and y = −6x from x = 1 to x=3?.
kvasek [131]

Using integration, it is found that the area between the two curves is of 22 square units.

<h3>What is the area between two curves?</h3>

The area between two curves y = f(x) and y = g(x), in the interval from x = a to x = b, is given by:

A = \int_{x = a}^{x = b} |f(x) - g(x)| dx

In this problem, we have that:

f(x) = 6x^2 - 18x, g(x) = -6x, a = 1, b = 3.

Hence, the area is:

A = \int_{1}^3 |6x^2 - 12x| dx

A = |x^3 - 6x^2|_{x = 1}^{x = 3}

Applying the Fundamental Theorem of Calculus:

A = |3^3 - 54 - 1^3 + 6|

A = 22

The area between the two curves is of 22 square units.

Four cups of a salad blend containing 40% spinach is mixed with an unknown amount of a salad blend containg 55% spinach. The res
Klio2033 [76]

Answer: 12 cups of salad blend are in the resulting mixture

Explanation:

Since we have given that

4 cups of a salad blend contains 40% spinach

Using mixture allegation method, we get that

8 cups of a salad blend contains 55% spinach as shown in the figure below.

Now, we need to find the number of cups of salad in the resulting mixture,

0.4\times 4+0.55\times 8=0.5\times x\\\\1.6+4.4=0.5x\\\\6=0.5x\\\\\frac{6}{0.5}=x\\\\12=x

Hence, 12 cups of salad blend are in the resulting mixture .
