Answer:

20.04 units

Step-by-step explanation:

The diagram shows right triangle ABC. Use the definition of the cosine:

\cos \angle C=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}\\ \\\cos \angle C=\dfrac{BC}{AC}\\ \\\cos 51^{\circ}=\dfrac{BC}{27}\\ \\BC=27\cdot \cos 51^{\circ}\\ \\BC\approx 20.04\ units

Investment increase exponentially by about 26% every 3 years. if you start with $2,000 investment how much money would you have
TEA [102]

Using an exponential function, it is found that you would have an amount of $64,060 in 45 years.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, considering the initial value of A(0) = 2000, with a growth rate of r = 0.26 each 3 years, the equation is given by:

A(t) = 2000(1.26)^{\frac{t}{3}}

In 45 years, the amount will be given by:

A(45) = 2000(1.26)^{\frac{45}{3}} = 64060

Answer:

we have:

(xy²)³ = x³.(y²)³ = x³y⁶ (1)

(xy³)² = x².(y³)² = x²y⁶ (2)

from (1)(2) => (xy²)³ isnt the same as (xy³)²
