Answer:

h = 3\sqrt{3}

c = 4\sqrt{2}

Step-by-step explanation:

✔️Finding h using trigonometric ratio:

Reference angle = 60°

Opposite = h

Adjacent = 3

Thus:

tan(60) = \frac{h}{3}

\sqrt{3} = \frac{h}{3} (tan 60 = √3)

Multiply both sides by 3

3\sqrt{3} = h

h = 3\sqrt{3}

✔️Finding c using trigonometric ratio:

Reference angle = 45°

Hypotenuse = 8

Adjacent = c

Thus:

cos(45) = \frac{c}{8}

\frac{\sqrt{2}}{2} = \frac{c}{8} (cos 45 = √2/2)

Multiply both sides by 8

\frac{\sqrt{2}}{2} \times 8 = c

\sqrt{2} \times 4 = c

c = 4\sqrt{2}

Find the following products:
baherus [9]

Answer:

i. x^2 – 1

ii. x^3 – 1

iii. x^4 - 1

Step-by-step explanation:

Products are obtained by multipliyng each left term by each rigth term as follows:

i. (x- 1)(x+ 1) = (x^2  – x + x - 1) = x^2 – 1 (equal terms with opposite sign substracts and the result is 0)

ii. (x- 1)(x^2 + x + 1) = (x^3 – x^2 + x^2 – x + x – 1) = x^3 – 1

iii. (x- 1)(x³ + x² + x + 1) = (x^4 – x^3 + x^3 – x^2 + x^2 – x + x – 1) = x^4 - 1

Inverse Function:<br> f-¹ (- 3)<br> f(x) = 6x - 12
sp2606 [1]
       f(x) = 6x - 12
          y = 6x - 12
  y + 12 = 6x - 12 + 12
  <u>y + 12</u> = <u>6x</u>
      6         6
¹/₆y + 2 = x
          y = ¹/₆x + 2
     f⁻¹(x) = ¹/₆x + 2
    f⁻¹(-3) = ¹/₆(-3) + 2
    f⁻¹(-3) = -¹/₂ + 2
    f⁻¹(-3) = 1¹/₂
(x, f⁻¹(x)) = (-3, 1¹/₂)
