What is the Pythagorean Theorem?The Pythagorean Theorem states that in the case of a right triangle, the square of the length of the hypotenuse, which is the longest side, is equals to the sum of the squares of the lengths of the other two sides.
Hence the equation for the theorem is given as follows:
c² = a² + b².
In which:
c > a and c > b is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.For the triangle in this problem, we have that:
The sides are d ft and 90 ft.The hypotenuse is of 409 ft.Hence the distance is obtained as follows:
d² + 90² = 409²
\(d = \sqrt{409^2 - 90^2}\)
d = 399 ft.

A flat circular plate has the shape of the region x squared plus y squared less than or equals 1.The plate, including the boundary where x squared plus y squared equals 1,is heated so that the temperature at the point (x comma y )is Upper T (x comma y )equalsx squared plus 2 y squared minus three halves x.Find the temperatures at the hottest and coldest points on the plate.
Answer:
We have the coldest value of temperature \(T(\frac{3}{4},0) = -9/16 \). and the hottest value is \(T(-(3/4),\frac{\sqrt{7}}{4})=\frac{5}{16}\).
Step-by-step explanation:
We need to take the derivative with respect of x and y, and equal to zero to find the local minimums.
The temperature equation is:
\(T(x,y)=x^{2}+2y^{2}-\frac{3}{2}x\)
Let's take the partials derivatives.
\(T_{x}(x,y)=2x-\frac{3}{2}=0\)
\(T_{y}(x,y)=4y=0\)
So, we can find the critical point (x,y) of T(x,y).
\(2x-\frac{3}{2}=0\)
\(x=\frac{3}{4}\)
\(4y=0\)
\(y=0\)
The critical point is (3/4,0) so the temperature at this point is: \(T(\frac{3}{4},0)=(\frac{3}{4})^{2}+2(0)^{2}-(\frac{3}{2})(\frac{3}{4})\)
\(T(\frac{3}{4},0)=-\frac{9}{16}\)
Now, we need to evaluate the boundary condition.
\(x^{2}+y^{2}=1\)
We can solve this equation for y and evaluate this value in the temperature.
\(y=\pm \sqrt{1-x^{2}}\)
\(T(x,\sqrt{1-x^{2}})=x^{2}+2(1-x^{2})-\frac{3}{2}x\)
\(T(x,\sqrt{1-x^{2}})=-x^{2}-\frac{3}{2}x+2\)
Now, let's find the critical point again, as we did above.
\(T_{x}(x,\sqrt{1-x^{2}})=-2x-\frac{3}{2}=0\)
\(x=-\frac{3}{4}\)
Evaluating T(x,y) at this point, we have:
\(T(-(3/4),\sqrt{1-(-3/4)^{2}})=-(-\frac{3}{4})^{2}-\frac{3}{2}(-\frac{3}{4})+2\)
\(T(-(3/4),\frac{\sqrt{7}}{4})=\frac{5}{16}\)
Now, we can see that at point (3/4,0) we have the coldest value of temperature \(T(\frac{3}{4},0) = -9/16 \). On the other hand, at the point \(-(3/4),\frac{\sqrt{7}}{4})\) we have the hottest value of temperature, it is \(T(-(3/4),\frac{\sqrt{7}}{4})=\frac{5}{16}\).

The order of operations (PEMDAS) states that we should perform multiplication and division before addition and subtraction. Using this order, we get:
244 - (33456 / 3456) * 345 + 13.55 - 2
= 244 - 97.02 * 345 + 13.55 - 2
= 244 - 33494.1 + 13.55 - 2

Preliminary data analyses indicate that you can reasonably apply the z-interval procedure. Find a 90% confidence interval for the mean number of tongue flicks per 20 minutes for all juvenile common lizards. Assume a population standard deviation of 190.0. Note: The sum of the data is 8551.
Confidence interval:
We can see here that the 90% confidence interval will be: 420.2 to 585.8.
What is confidence interval?An interval of values known as a confidence interval is one that is likely to include the real value of a population parameter. A confidence interval of 95%, for instance, indicates that there is a 95% likelihood that the population parameter's real value falls inside the interval.
We will find the sample mean first:
Sample mean = sum of data points / number of data points
Sample mean = 8551 / 17 = 503
Then the standard error will be:
Standard error = population standard deviation / square root of number of data points
Standard error = 190 / √(17) = 41.7
Confidence interval = Sample mean ± 1.645 × standard error.
where 1.645 is the z-score for a 90% confidence interval.
Confidence interval = 503 ± 1.645 * 41.7 = 420.2 to 585.8

In the given parallelogram ABCD the values for variables are - g = 6, y = 5 and x = 4.
What is a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side.
We know that in a parallelogram, opposite sides are congruent and parallel, and diagonals bisect each other.
Using this information, we can set up equations to solve for the variables.
From the given information, we have -
AE = CE = 2x - 5 = 5x - 17 (since diagonals bisect each other at point E)
BE = x + 2
DE = BE = (x + 2) = g (since diagonals bisect each other at point E)
We also know that opposite sides of a parallelogram are parallel.
Therefore, 10 is parallel to 2y, which means they have the same slope. We can write this as -
10/1 = 2y/1
10 = 2y
y = 5
Now we can use equation (1) to solve for x -
2x - 5 = 5x - 17
12 = 3x
x = 4
Finally, we can use x to solve for g -
(x + 2) = g
(4 + 2) = g
g = 6
Therefore, the values of x, y, and g are 4, 5, and 6, respectively.

Seventy percent of the children went on the excursion. If 27 stayed at school, how many went?
By using the Unitary Method we get the number of children who went on an excursion was 63. Thus, the total number of children at school is 90.
We are given that,
No. of children who stayed at school is 27,
Also, 70% of the children went on an excursion.
Suppose, the total number of children in percentage is 100%
Out of which 70% went on an excursion
Thus, the children who stayed at school is 100% - 70% = 30%
By using the Unitary method, we can find out the number of 70% of children.
If 30% of the children are 27
Then 70% of the children are = 27 × 100

The length of a rectangle is four times its width. If the perimeter of the rectangle is 180 ft, find its area
The area of the rectangle is 1296 square feet.
Let's denote the width of the rectangle as "w" and its length as "4w" since the length is four times the width.
The formula for the perimeter of a rectangle is given by:
P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
Given that the perimeter of the rectangle is 180 ft, we can write the equation as:
180 = 2(4w + w)
Simplifying the equation:
180 = 2(5w)
180 = 10w
w = 18
So, the width of the rectangle is 18 ft.
Now, we can find the length of the rectangle:
Length = 4w = 4(18) = 72 ft
The area of a rectangle is given by the formula:
\(A = l \times w,\)
where A is the area,
l is the length,
and w is the width.
Substituting the values we found:
Area \(= 72 ft \times 18 ft = 1296 ft^2\)

If the area of a square inscribed in a circle is
25, what is the area of the circle?
The area of a square inscribed in a circle is 25, then the area of the circle is 25π/2 or approximately 39.27 square units.
To solve this problem, we can use the relationship between the area of a square inscribed in a circle and the area of the circle itself.
When a square is inscribed in a circle, the diagonal of the square is equal to the diameter of the circle. Let's assume that the side length of the square is 's' and the radius of the circle is 'r'.
We are given that the area of the square is 25, so we can find the side length of the square:
Area of square = \(s^2 = 25\)
Taking the square root of both sides, we get:
s = √25 = 5
Since the diagonal of the square is equal to the diameter of the circle, we can find the diameter of the circle:
Diagonal = Diameter = s√2 = 5√2
The radius of the circle is half the diameter, so:
Radius = 5√2 / 2 = (5√2)/2
Now, we can calculate the area of the circle using the formula:
Area of circle = \(\pi r^2\)
Substituting the value of the radius, we get:
Area of circle = π((5√2)/\(2)^2\) = π(25/2) = 25π/2
Therefore, the area of the circle is 25π/2 or approximately 39.27 square units.
