Using Squeeze/Sandwich Theorem,
Calculate the limit of : lim [(x,y) -> (0,0)] (3 . x^2 . y / (x^2 + y^2))
Using Squeeze theorem, the limit of the function is 0
What is the LimitThe Squeeze Theorem states that if f(x,y) <= g(x,y) <= h(x,y) for all x,y in a region around (x0,y0) and lim (x,y)->(x0,y0) g(x,y) = L, then lim (x,y)->(x0,y0) f(x,y) = lim (x,y)->(x0,y0) h(x,y) = L.
We can use the Squeeze Theorem to find the limit of the given function by finding two other functions that bound it and have known limits as (x,y) approaches (0,0).
We can see that
(x^2+y^2)/(x^2+y^2) <= 3x^2y/(x^2+y^2) <= (3xy)/(x^2+y^2)
As x,y approaches 0, the first inequality approaches 1 and the second one approaches 0, so the limit of the given function is also 0.
Therefore, lim [(x,y) -> (0,0)] (3 . x^2 . y / (x^2 + y^2)) = 0.

given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or
significantly high. For such data, would a brain volume of 1386.4 cm³ be significantly high?
If the brain volumes (cm³) of 20 brains have a mean of 1085.2 cm³ and a standard deviation of 125.6 cm³. For such data: it is significantly low for a brain because 1386.4 cm³ is less than the upper limit.
How to find the lower and upper limits?Mean = 1085.2 cm³
Standard deviation = 125.6 cm³
Hence,
Lower limit = Mean - 2 x Standard deviation
Lower limit =1085.2 - 2 x 125.6
Lower limit =1161.2 - 251.2
Lower limit =910
Upper Limit = Mean + 2 x Standard deviation
Upper Limit = 1161.2 + 2 x 125.6
Upper Limit =1161.2 +251.2
Upper Limit =1412.4
The limit of values is from 910 to 1412.4.
A value below 910 will be is considered low and a value above 1412.4 will be considered high

f(g(f(1))) = 45 — needs to use the equationg(f(g(0))) = 3Step-by-step explanation:
You want to use the graph to evaluate the compositions ...
f(g(f(1)))g(f(g(0)))where f(x) = x² -2x -3, and g(x) = x -2.
Reading the graphTo find the value of a graphed function, locate the function argument on the x-axis and find the point of intersection of that vertical line with the graph. The y-coordinate of that point is the function value.
f(g(f(1)))Here, we're asked to read the graph to find f(1), use that value to find g(f(1)), then use that value to find f(g(f(1))). This last value is f(-6), which is off the top of the graph. We need to use the equation to find the value:
f(x) = (x -2)x -3
f(-6) = (-6 -2)(-6) -3 = 48 -3 = 45
The value of f(g(f(1))) is 45. The equation must be used for this.
g(f(g(0)))Reading the graph for g(0), we find the value to be -2. Then f(-2) is 5, and g(5) is 3.
The value of g(f(g(0))) is 3.

The rate of change is $ 0.75 per attraction.
The table on the number of tickets and total cost is:
Number of tickets 1 5 10 15
Total cost $ 10. 75 $ 13.75 $17.50 $ 21. 25
How to find the cost of tickets ?The number of tickets that Sam can buy when he has $ 37 is:

Winston leaned a 32-foot ladder against the side of a building. The
base of the ladder is 3 feet from the base of the building. The top of
the ladder is 15 feet from the top of the building. How tall is the
building? Provide an answer accurate to the nearest tenth of a foot.
Answer:
the building is approximately 28.3 feet tall, accurate to the nearest tenth of a foot.
Step-by-step explanation:
The height of the building can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the building is the hypotenuse, and the base of the ladder and the top of the ladder form the other two sides.
The height of the building can be found using the following formula:
h = √(32^2 - 15^2)
h = √(1024 - 225)
h = √(799)
h ≈ 28.3 ft

Write the equation of the line that passes at the point (-8,5) with the slope m=-1 in slope-intercept form.
Answer:
y = -x - 3
Step-by-step explanation:
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
Given that the point (-8,5) lies on the line and the slope of the line is m=-1, we can use the point-slope form of a linear equation to write the equation of the line.
The point-slope form of a linear equation is y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
So substituting the given point (-8,5) and slope m=-1 into the point-slope form, we get:
y - 5 = -1(x + 8)
Simplifying, we get:
y = -x - 3
This equation is the slope-intercept form of the line that passes through the point (-8,5) and has a slope of -1.

Find an ordered pair (x, y) that is a solution to the equation.
-x+2y=7
(x, y) = (_, _)
To answer this, you get to pick any x-value and then solve for y OR you can pick any y-value and solve for x.
For this one, let's pick x = 3. We'll then substitute 3 in for x in the equation:
- (3) + 2y = 7
and then solve for x:
-3 + 2y = 7
Add 3 to both sides:
2y = 10
Divide by 2 on both sides:
y = 5
This shows that (3,5) is a solution for the equation.
Again, you could pick any x-value and solve for y OR pick any y-value and solve for x. There are an infinite number of solutions.
Assuming a Perfectly Competitive firm has the following cost function: TC = 1000 + 600Q – 10Q2 + 0.05Q3 . Minimum AVC is
Therefore , to calculate the average AVC, use the formula: TC at 0 output is 5, which equals fixed cost (FC) of 5.
How are AVC, AFC, and TC calculated?The fixed cost per unit of output is known as the AFC, and the variable cost per unit of output is known as the AVC. We previously stated that Bob's Bakery can produce 100 loaves with FC = 40, VC = 500, and TC = 540. ATC = TC/Q = 540/100 = 5.4 as a result. Additionally, AVC = 500/100 = 5 and AFC = 40/100 = 0.4.
Here,
Total cost is equal to total fixed cost plus total variable cost, or TC.
In order to obtain the VC at each output, we must first subtract 5 from the TCs for all subsequent output levels.
AVC is now equal to VC divided by Q.

Driving down a mountain, Bob Dean finds that he descends 3200 feet in elevation by the time he is
3.9 miles (horizontally) away from the high point on the mountain road. Find the slope of his descent. (1 mile = 5280 feet).
Answer:
-0.155
Step-by-step explanation:
You want the slope of Bob's descent when he descends 3200 feet in a horizontal distance of 3.9 miles.
SlopeTo find the slope of Bob Dean's descent, we can use the formula:
slope = (change in elevation) / (change in horizontal distance)
ApplicationIn this case, the change in elevation is 3200 feet and the change in horizontal distance is 3.9 miles.
slope = -3200 feet / (3.9 miles)
To convert the horizontal distance to feet, we multiply by 5280 (the number of feet in a mile)
slope = -3200 feet / (3.9 * 5280 feet)
slope = -3200 / 20,592
slope ≈ -0.1554
The slope of Bob Dean's descent is about -0.155.

b) Three interior angles of an n-sided polygon are 136', 138' and 146'. The remaining angles are 165' each. Find the value of n.
By solving a linear equation we will see that the polygon has 19 sides.
How to find the number of sides of the polygon?Remember that for a polygon of n sides, the sum of the interior angles is equal to:
(n - 2)*180°
Here we also know that 3 angles are:
136°, 138°, and 146°
And the rest of the angles (n - 3) angles are of 165° each.
Then the sum of the interior angles gives:
136° + 138° + 146° + (n - 3)*165°
And that must be equal to the expression above, so we can write the linear equation:
136° + 138° + 146° + (n - 3)*165° = (n - 2)*180°
420° + n*165° - 495° = n*180° - 360°
n*165° - 75° = n*180° - 360°
360° - 75° = n*180 - n*165
285° = n*15°
285°/15° = n
19 = n
