Answer:6.37%
Step-by-step explanation:
Currently, the total number of computer programmers employed in a certain country is approximately
455000
By next decade, this number is expected to increase to 484000
To determine the increase in the number of computer programmers in a decade, we will subtract the current number of computer programmers from the expected number of computer programmers in the next decade. It becomes
484000 - 455000 = 29000
To determine the percent increase, we will divide the increase in computer programmers by the number of computer programmers currently and multiply by 100. It becomes
29000/455000 × 100
= 6.37%
Answer: x = H(x) + 3
Step-by-step explanation: The inverse function is x expressed with H(x). There aren't always inverse functions but in this case you just put the fraction from the right hand side to the left hand side. After the divison you get what I wrote.
Answer:
y=-2x+1
Step-by-step explanation:
to find the slope use the formula (y2-y1)/(x2-x1)
-5-3= -8
3-(-1) = 4
-8/4 = -2
Answer:
θ = π n + π/2 for n element Z
Step-by-step explanation:
Solve for θ:
1 + 2 cos(2 θ) + cos^2(2 θ) = 0
Write the left hand side as a square:
(cos(2 θ) + 1)^2 = 0
Take the square root of both sides:
cos(2 θ) + 1 = 0
Subtract 1 from both sides:
cos(2 θ) = -1
Take the inverse cosine of both sides:
2 θ = 2 π n + π for n element Z
Divide both sides by 2:
Answer: θ = π n + π/2 for n element Z
