~7)~
$(3×4×5)
=1.585 + 2 + 2.322
=5.907$
~8)
$(3÷2÷5)
=1.585 - 1 - 2.322
=-1.737$
9) $3log7(2) -2log7(3) + 4log7(3) -2log7(2)
=0.356+2(0.565)
=1.486$
9) $x(x+2)=8
x=2$
10) $x/(2x+3)=1/9
9x=2x+3
x=3/7$

$f(x)= \frac{x}{2} -2$ and $g(x)=2 x^{2} +x-3$
(f+g)(x) = $\frac{x}{2} -2+2 x^{2} +x-3$
combining like terms gives you answer choice B

The diameter of a circular tablecloth is 72 inches. Find the area and circumference. Use 3.14 as an approximation for pi.

nalin [4]

Answer:

Part 1) The area is $A=4,069.44\ in^{2}$

Part 2) The circumference is $C=226.08\ in$

Step-by-step explanation:

step 1

Find the area

we know that

The area of a circle (circular tablecloth) is equal to

$A=\pi r^{2}$

we have

$r=72/2=36\ in$ ------> the radius is half the diameter

$\pi =3.14$

substitute

$A=(3.14)(36)^{2}$

$A=4,069.44\ in^{2}$

step 2

Find the circumference

we know that

The circumference of a circle (circular tablecloth) is equal to

$C=\pi D$

we have

$D=72\ in$

$\pi =3.14$

substitute

$C=(3.14)(72)$

$C=226.08\ in$
