Let f(x) = sin(x) + icos(x). Show that |f(x)| = 1.

Oksanka [162]

F(x) = sin(x) + icos(x)
|f(x)| = sqrt(sin^2(x) + cos^2(x)) = sqrt(1) = 1

Therefore, |f(x)| = 1

Solve the quadratic equation 3x² + 2x-4=0<br> Give your answers to 2 decimal places.

GalinKa [24]

3x² + 2x - 4 = 0

Δ = b² - 4.a.c

Δ = 2² - 4 . 3 . -4

Δ = 4 - 4. 3 . -4

Δ = 52

x = (-b +- √Δ)/2a

x' = (-2 + √52)/2.3

x'' = (-2 - √52)/2.3

x' = 0,8685170918213297

x'' = -1,5351837584879966

2 Decimal places

x' = 0,87

x'' = -1,54

Equations for height of trapezoid

devlian [24]

Answer:

$h= \frac{\sqrt{(-a+b+c+d)(a-b+c+d)(a-b+c-d)(a-b-c+d)}}{2|b-a|}$

Step-by-step explanation:

The height (or altitude) is the perpendicular distance between the bases.
In the case that the two bases have different lengths (a ≠ b), the height of a trapezoid h can be determined by the length of its four sides using the formula

$h= \frac{\sqrt{(-a+b+c+d)(a-b+c+d)(a-b+c-d)(a-b-c+d)}}{2|b-a|}$

where c and d are the lengths of the legs.
