D:x\geq-5 \wedge x\geq10\\
D:x\geq10\\\\
\sqrt{n+5}-\sqrt{n-10}=1\\
\sqrt{n+5}=1+\sqrt{n-10}\\
n+5=1+2\sqrt{n-10}+n-10\\
2\sqrt{n-10}=14\\
\sqrt{n-10}=7\\
n-10=49\\
n=59

What is the total area of this composite figure rounded to the nearest hundredth?
Alex777 [14]

Answer:

39.53 ft^2

Step-by-step explanation:

We can find the area of the rectangle

A = l*w

   = 12*3 = 36

And the area of the semicircle

A = 1/2 pir^2

The diameter is 3, the radius is 3/2

   =1/2 pi* (3/2)^2

   = 1/2 *3.14 * 9/4

3.5325

Add the two areas together

36+3.532539.5325

Rounding to the nearest hundredth

39.53 ft^2

IRINA_888 [86]

Step-by-step explanation:

step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.

step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.
