Segments <em>AB</em> and <em>CD</em> are perpendicular.
Answer:
12³
Step-by-step explanation:
A number in the <u>exponential form</u> has a small number on the top right of the base, looking like this, if "x" is the exponent and "B" is the base.
Bˣ
Value of an number in exponential form:
"x" is the number of time you multiply the base, "B" by itself.
Examples:
3² = 3 * 3
3⁴ = 3 * 3 * 3 * 3
5¹ = 5
The formula for the volume of a cube is V = s³; "s" is the length of one side.
If the length is 12, substitute 12 for "s".
V = 12³ Volume of cube in exponential form
Other answers:
12 x 12 x 12
This expression also gives you the volume of the cube, but it is not in exponential form. It is in expanded form, (V = l x w x h; length times width times height).
3¹²
This option switches the base with the exponent.
12
This option only gives the length of one edge.
Answer:
b = 6
Step-by-step explanation:
solve the second equation for 'y':
-3x + 1/2y = -3
add 3x to each side to get:
1/2y = 3x - 3
multiply all terms by 2 to eliminate the denominator to get:
y = 6x - 6
now compare '6x-6' with '6x-b'
you want both expressions to be equal because then there are an infinite number of solutions:
b = 6
