Answer:
Measure of fourth angle of quadrilateral is:
100
Step-by-step explanation:
We know that the sum of angles in a quadrilateral is 360°
Three of the angles of a quadrilateral are 120 48 and 92
we have to find the sum of the fourth angle of the quadrilateral
Let measure of fourth angle be x
120+48+92+x= 360
i.e. 260+x = 360
Subtracting both sides by 260, we get
x= 100
Hence, Measure of fourth angle of quadrilateral is:
100

1). Take care of the (x+1)² . . .
(x + 1)² = x² + 2x + 1
2). Take care of the (x-1)² . . .
(x - 1)² = x² - 2x + 1
The problem says that (the first expression) minus (the second expression) is 32 .
(x² + 2x + 1) - (x² - 2x + 1) = 32
Can you handle this ?
Only one more touchy point to take care of . . . removing the second parentheses.
Since there's a negative sign before it, that changes the sign of everything inside:
(x² + 2x + 1) PLUS (- x² + 2x - 1) = 32
Now you can just erase all the parentheses:
x² + 2x + 1 - x² + 2x - 1 = 32
Now I'm just going to write the things on the left side in a different order,
without changing anything:
x² - x² + 2x + 2x + 1 - 1 = 32
Isn't that neat ? ! ?
What you have now is:
4x = 32
Divide each side by 4 :
x = 8
Just watch how slick that works:
(x + 1)² - (x - 1)² = ?
(x + 1) = 9 (x - 1) = 7
(9)² - (7)² = 81 - 49 = . . . . . . . . 32 !

Step-by-step explanation:
f(0) = 4 and g(–2) = 4
f(2) = 0 and g(–2) = 0
f(–2) = 0 and g(–2) = 0
Answers
Answer:
C. f(2) = 0, and g(-2) = 0
Step-by-step Explanation:
From the graph given, the line for f(x) and g(x) intercept each other at x = 0, when y = 4, that is f(0) = 4 and also g(0) = 4.
From the graph, on the line of g(x), when x = -2, y = 0, that is g(-2) = 0.
Also for f(x), when x = 2, y = 0. That is, f(2) = 0.
Therefore, the statement that is true about the graphed function is:
f(2) = 0, and g(-2) = 0

Answer: the expected population of the city in 30 years is 5470781
Step-by-step explanation:
The population growth is exponential. The growth rate is exponential. We would apply the formula for exponential growth which is expressed as
A = P(1 + r)^t
Where
A represents the population after t years.
t represents the number of years.
P represents the initial population.
r represents rate of growth.
From the information given,
P = 3.5 × 10^6
r = 1.5% = 1.5/100 = 0.015
t = 30 years
Therefore,
A = 3.5 × 10^6(1 + 0.015)^30
A = 3.5 × 10^6(1.015)^30
A = 5470781
