4 0

Answer:

f(-2) = 19

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² - 3x + 1

f(-2) is x = -2

<u>Step 2: Solve</u>

  1. Substitute:                    f(-2) = 3(-2)² - 3(-2) + 1
  2. Exponents:                    f(-2) = 3(4) - 3(-2) + 1
  3. Multiply:                        f(-2) = 12 + 6 + 1
  4. Add:                              f(-2) = 19

Katarina [22]

Complete Question

The length of the guy wire supporting a cell tower is 120 m. The guy wire is anchored to the ground at a distance of 80 m from the base of the tower to the nearest hundredth of a meter how tall is the tower?

Answer:

89.44m

Step-by-step explanation:

We solve this question using the Pythagoras Theorem

This is given as:

Hypotenuse² = Opposite ² + Adjacent ²

Hypotenuse = Length of the guy wire = 120m

Adjacent = Distance from the base of the tower = 80m

Opposite = Height of the building = x

Hence:

120² = x² + 80²

Collect like terms

x² = 120² - 80²

x = √120² - 80²

x = √(8000)

x = 89.4427191 m

Approximately the height of the tower is = 89.44m

F(x)=3cos2x-2sinx olduğuna göre f(3π\2) ifadesinin değeri kaçtır​
HACTEHA [7]

Cevap:

-1

Adım adım açıklama:

F (x) = 3cos2x-2sinx fonksiyonu verildiğinde, f (3π \ 2) bulacağız.

Vekil;

f (3π / 2) = 3kos2 (3π / 2) -2sin (3π / 2)

f (3π / 2) = 3cos3π - 2sin (3π / 2)

f (3π / 2) = 3 (-1) -2 (-1)

f (3π / 2) = -3 + 2

f (3π / 2) = -1

Dolayısıyla f (3π / 2) değeri -1'dir
