$\pi r ^{2} = \pi (5) ^{2}=78.54" ^{2}$

The area of a circle of radius r is pi*r^2

Hence here the area is A=5^2*pi=25pi~78.5 square inches

Katena32 [7]

Okay so first I am taking it that you have to subtract 24k from the 104k which brings it to 80,000.
I am also taking it that the 8.5% is suppose to be in decimal form which makes it .085%
Take the 80,000 and use the monthly payment formula, which is really easy to use.
Monthly payment should be 644.18

Solve for x in the given interval.<br><br> sec x= -2√3/3, for π/2 ≤x≤π

drek231 [11]

Answer:

b. $x=\frac{5\pi}{6}$

Step-by-step explanation:

The given function is

$\sec x=-\frac{2\sqrt{3} }{3},\:\:for\:\:\frac{\pi}{2}\le x \le \pi$

Recall that the reciprocal of the cosine ratio is the secant ratio.

This implies that;

$\frac{1}{\cos x}=-\frac{2\sqrt{3} }{3}$

$\Rightarrow \cos x=-\frac{3}{2\sqrt{3} }$

$\Rightarrow \cos x=-\frac{\sqrt{3}}{2}$

We take the inverse cosine of both sides to obtain;

$x=\cos^{-1}(-\frac{\sqrt{3}}{2})$

$x=\frac{5\pi}{6}$

The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +

prisoha [69]

Let

x------> the first even integer

x+2---->the second even integer

x+3---->the third even integer

we know that

$x+(x+2)+(x+4)=36$ -----> equation that represent the situation

solve for x

Combine like terms in the left side

$(x+x+x)+(2+4)=36$

$3x+6=36$

therefore

<u>the answer is the option B</u>

$3x+6=36$
