<h3>Answer ↓</h3>

option B.

Calculations ↓

First, let's think of two numbers so that :

  • if we multiply these numbers, we'll get 4
  • if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)

Find g(x) where g(x) is the translation 3 units right of f(x)=x^2
Fed [463]

Answer:

  g(x) = x^2 -6x +9

Step-by-step explanation:

A function f(x) translated right h units and up k units will become ...

  g(x) = f(x -h) +k

You want the function f(x) = x^2 to be translated right h=3 units, so it will become ...

  g(x) = f(x -3) = (x -3)^2

  g(x) = x^2 -6x +9

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centim
Daniel [21]
The answer is 1808.64 ft²

To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2

The blueprint:
d = 18 cm
r = 18/2 = 9 cm

<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft

The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft

A = 24² * 3.14
A = 1808.64 ft²
