Part A:
If (7^2)^x = 1 then the value of x is equal 0
Because when x = 0 the
(7^2)^0 = 1 ; 7^0 = 1
Any number with 0 exponent is always equal 0, except 0.
Part B:
If (7^0)^x = 1, then the value of x is all real number
Because when 0 multiplies any number, it is always equal 0. So then 7^0 is always equal 1.
Example
if x = 1 then (7^0)^1 = 7^0 = 1
if x = -1 then (7^0)^(-1) = 7^0 = 1
if x = 1000 then (7^0)^(1000) = 7^0 = 1
Given:
JK is tangent to a circle with center H
To find:
The length of HK.
Solution:
The image is attached below.
JK = 8 mi, HJ = 15 mi
JK is tangent to a circle.
The tangent is always perpendicular to the radius.
Therefore, m∠J = 90°
Using Pythagoras theorem:
HK² = JK² + HJ²
HK² = 8² + 15²
HK² = 64 + 225
HK² = 289
HK² = 17²
Taking square root on both sides.
HK = 17
The length of HK is 17 mi.
We are going to want to change any mixed number into an improper fraction. 2 3/4 is 11/4 and 1 2/5 is 7/5.
We are going to set up a proportion where the lbs are on the top and the money is on the bottom. x is going to be how much it costs for 2 3/4 lbs of lunch meat.
(7/5)/3.36 = (11/4)/x
Cross multiplication \/
7/5x = 9.24
x = 6.60
As a final answer, the 2 3/4 lbs of lunch meat cost $6.60
