X can be any number, so the domain is all real numbers (-∞, +∞)
y is always larger than 0 in this case, so the range is all real numbers larger than 0 (0, +∞)

Answer:

Step-by-step explanation:

because if you input 18.25 into the equation and solve you get and non-whole number of 2.608.

A state map has a circle-shaped compass. If the radius of the compass is 15 millimeters, what is the approximate area of the com

GuDViN [60]

The area of a circle by definition is given by:
A = pi * r ^ 2
Where,
r: radius
Substituting the values we have:
A = (3.14) * (15) ^ 2
A = 706.5 mm ^ 2
Answer:
The approximate area of the compass is:
A = 706.5 mm ^ 2

4a – 16 = a - 15 how do I solve

miv72 [106K]

Answer:

a = $\frac{1}{3}$

Step-by-step explanation:

4a -16 = a - 15

both left and right -a

then

4a - 16 -a = a - 15 -a

then

4a -a -16 = a -a -15

then

3a -16 = -15

both left and right + 16

then

3a -16 + 16 = -15 + 16

then

3a = 1

both left and right ÷3

then

3a ÷ 3 =1 ÷ 3

then

a = $\frac{1}{3}$
