A rectangle is 60 cm long and 20 cm wide. Find, to the nearest tenth of a degree, the acute angle formed at the intersection of
Yakvenalex [24]

Answer:

36.9°

Step-by-step explanation:

As shown in the diagram attached,

θ is the acute angle formed at the intersection of the diagonals of the rectangle.

From the diagram,

tan(θ/2) = 10/30

tan(θ/2) = 1/3

θ/2 = tan⁻¹(1/3)

θ/2 = 18.43

Therefore,

θ = 18.43×2

θ = 36.87

θ = 36.9°

Hence the acute angle formed is 36.9°

Logarithmic and Exponential Forms of Equations In Exercise, write the logarithmic equation as an exponential equation, or vice v
gavmur [86]

Answer:

\log_e(4.4816) = 1.5

Step-by-step explanation:

We are given the following in the question:

e^{1.5} = 4.4816...

We have to convert this equation into logarithmic equation.

Relation between exponent and logarithmic:

  • Logarithmic functions are the inverses of exponential functions.
  • The logarithmic function y = \log_ax is defined to be equivalent to the exponential equation x = a^y

For the given expression a = e, y = 1.5 and x = 4.4816...

We can express them as:

e^{1.5} = 4.4816...\\\text{Taking log on both sidses}\\\log(e^{1.5}) = \log(4.4816)\\\log_e(4.4816) = 1.4998 \approx 1.5\\\log_e(4.4816) = 1.5
