Write the equivalent logarithmic equation to 10^a = x+b

MA_775_DIABLO [31]

Answer:

The answer to your question is log₁₀ x + b = a

Step-by-step explanation:

General formula

Logarithmic function Exponential function

log ₐ b = c $b^{c} = a$

a = antilogaritm c = exponent

b = base b = base

c = logaritm a = power

In your problem

10 = base

a = exponent

x + b = power

Exponential function log₁₀ x + b = a

While sailing, Jacob is 150 feet from a lighthouse. The angle of elevation from his feet on the boat (at sea level) to the top o

Vlada [557]

Answer:

The height of the lighthouse is approximately 166.6 feet.

Step-by-step explanation:

Let the height of the lighthouse be represented by s, then;

Tan 48° = (opposite) ÷ (adjacent)

Tan 48° = s ÷ 150

⇒ s = 150 × Tan 48°

= 150 × 1.1106

= 166.59

s ≅ 166.6 feet

Therefore, the height of the lighthouse is approximately 166.6 feet.
