First you do 35.5ft2 – 26.5ft2 to find the area of the square.
You get 9ft2 as your answer.

Then you would find the square root of 9, which just happens to be 3.

Each side of the square = 3ft

Janice is thinking of two numbers. She says that two times the first number plus the second number is 41. In addition, the firs

Rudiy27

Let one of the number be x and the other be y

<span>two times the first number plus the second number is 41
</span>2x + y = 41

<span>the first number plus three times the second number is 73
x + 3y = 73

</span>2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)

From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21

Ans: x = 10, y = 21

Analyzing a Graph In Exercise, analyze and sketch the graph of the function. Label any relative extrema, points of inflection, a

vivado [14]

Answer:

analyzed & sketched

Step-by-step explanation:

We are given the function: y = In(x + 3)

So first we need to take the first derivative to find the interval of increase and decrease, then the second derivative to find the interval of concave up and concave down.

$y'=\frac{1}{x+3}$

$y''=-\frac{1}{(x+3)^2}$

So it is always increasing function, and always concave down function.

Since it is a logarithmic function, x>3.

So, x = 3 is vertical asymptote.

I attached the sketch as a picture.
