From right triangle trigonometry, we have the following:

\displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side }, 


where the "opposite side" means the opposite side to angle with measure 35^o, and "adjacent side" means the adjacent side to angle with measure 35^o.

tan(35^o) is a constant which can be found using a calculator.

In the calculator of the pc press: view - scientific - 35 - tan.

 This gives tan(35^o)=0.7


Thus, back in the equation \displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side } we substitute as follows and solve:


\displaystyle{0.7= \frac{x }{12 }\\\\

x=0.7\cdot12=8.4

The population of a town is 20,000 and is decreasing at a rate of 5% per year. What is the population after 23 years?
AVprozaik [17]
I believe the answer should be approximately 6,147 because you would plug into the equation y=20,000(.95)^t, where t=23.

Can the vertex also be a solution of a graphed parabola?
stiv31 [10]
One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.

Answer:

Circumference is 18.84 feet. Area is 28.26 square feet.

Step-by-step explanation:

Given:

Radius of the circle, r=3\textrm{ ft}

The value of \pi is 3.14.

Now, circumference of a circle of radius r=3 is given as:

Circumference=2\pi r=2\times 3.14\times 3=18.84\textrm{ ft}

Also, area of the circle of radius r=3 is given as:

Area=\pi r^{2}=3.14\times (3)^{2}=3.14\times 3\times 3=28.26\textrm{ }ft^{2}

Therefore, the circumference of the circle is 18.84 feet and area of the circle is 28.26 square feet.
