Answer:
<u>a. Symbolic names made up by the programmer that represents locations in the computer's RAM.</u>
Step-by-step explanation:
Note that in programming, variables value can change, depending on the instructions of the programmer.
For example, if two values 10 and 20 are to be stored in a program and used.
The Programmer would do the following:
-
Create variables with symbolic names,
- Store the values in those two variables,
- Retrieve and use the stored values from the variables.
<em>A variable name could be like age, sex, salary, year 2020 etc.</em>

X + 4 = 4x + 2
let’s put the x’s on one side and the numbers on the other
(whatever you do to one side, you have to do to the other)
x + 4 = 4x + 2
- 4 - 4x
x - 4x = 2 - 4
-3x = -2
—— ——
-3 -3
x = 2/3
to check this, we can put 2/3 in for x
(2/3) + 4 = 4(2/3) + 2
4 2/3 = 8/3 + 2
4 2/3 = 2 2/3 + 2
and there we can see both sides equal 4 and 2/3, making it true
Answer:
a = -0.5
b = −1.73
c = −0.70
d = 
≈ -0.70710678
Step-by-step explanation:
EXPLAIN Q(a):
sin(−30)
Use the property sin(−x)=−sin(x).
−sin(30)
Get the value of sin(30) from trigonometric values table.
-0.5
5w + 3.8 = 16.3
5w + 3.8 - 3.8 = 16.3 - 3.8
5w = 12.5
5w ÷ 5 = 12.5 ÷ 5
w = 2.5
Hope this helps!!
