First distribute: 8(4n)+8(13)
32n+104=6n
-32n      -32n
104=-26n
/-26  /-26
-4=n
8(4(-4)+13)=6(-4)
8(-3)=-24
-24=-24

8(4n + 13) = 6n
Use distributive property so :8 (4n) = 32n and 8(13) = 104
32n + 104 = 6n
Subtract 32n from each side and you will get:
104 = 26n
then you divide each side by 26 and your answer will be:
n = 4

Find the area of a sector with a central angle of 170° and a diameter of 9.1 cm. Round to the nearest tenth.
Nesterboy [21]
A central angle:
α = 170°
d = 9.1 cm
r = 9.1 : 2 = 4.55 cm
Area of a sector:
A = r² π α / 360°
A = ( 4.55 )² · 3.14 · 170° / 360°
A = 30.7 cm²

Describe a relationship modeled by the function f(x) = 4x3 − 72x2 + 320x
solmaris [256]

Answer:

  • A relationship modeled by the function f(x) = 4x³ - 72x² + 320x is the volume of a right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.

Explanation:

To find a relationship modeled by the given function it is recommendable to factor it.

The function is:

  • f(x)=4x^3-72x^2+320x

The first step to factor it is to extract common factor 4x:

  • f(x)=4x(x^2-18x+80)

The second step is to factor the quadratic trinomial.

That is made by writting it as a product of two binomials, for which the two constant terms add up - 18 and their product is 80. Those terms are -10 and - 8; so the two factors are (x - 10) and (x - 8), and the factored form is:

  • f(x)=(4x)(x-10)(x-8)

Then, a relationship modeled by that polynomial is the volume of right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.

  • x is the desired (unknown) length
  • 4x is 4 times the desired length
  • x - 10 is 10 less than the desired length
  • x - 8 is 8 less than the desired length

Thus, the volume of the prism is the product of the three factors:

  • Volume = (4x)(x-10)(x-8)
