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
Problem 4
Answer: 47
------------------------
Work Shown:
f(x) = x^2 - 7x + 3
f(x) = (x)^2 - 7(x) + 3
f(-4) = (-4)^2 - 7(-4) + 3 ... replace each x with -4
f(-4) = 16 - 7(-4) + 3
f(-4) = 16 + 28 + 3
f(-4) = 44 + 3
f(-4) = 47

Problem 5
Answer: See the attached image for the table
------------------------
Work Shown:
Plug in n = 27 and we get...
C = 26 + 10*n
C = 26 + 10*27
C = 26 + 270
C = 296
The input n = 27 leads to the output C = 296. This means that 27 people will have the cost be $296
Do the same for n = 39
C = 26 + 10*n
C = 26 + 10*39
C = 26 + 390
C = 416
The input n = 39 leads to the output C = 416. This means that 39 people will have the cost be $416
and also n = 43 as well
C = 26 + 10*n
C = 26 + 10*43
C = 26 + 430
C = 456
The input n = 43 leads to the output C = 456. This means that 43 people will have the cost be $456
Answer:
1.30 N
Step-by-step explanation:
All zero's preceding the first integers are never significant. For example: 0.0078 has two significant figures. All zero's after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures
Answer:
7
Step-by-step explanation:
13-6=7 the other line doesn't affect the answer because it isn't negative
