Using the Pythagorean Theorem, it is found that:
a) The hypotenuse is of 9.49 cm.
b) The new area of the triangle is of 30 cm².
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
For this problem, the sides are given as follows:
3 cm and 9 cm.
Hence the hypotenuse is given by:
h² = 3² + 9²
h = sqrt(3² + 9²)
h = 9.49 cm.
The hypotenuse is of 9.49 cm.
What is the area of a right triangle?The area of a right triangle of sides a and b is given by half the multiplication of the sides, as follows:
A = 0.5ab.
For this problem, we have that:
The side of 3 cm is increased by 2 cm, hence a = 5 cm.The side of 9 cm is increased by 3 cm, hence b = 12 cm.Then:
A = 0.5 x 5 x 12 = 30 cm².
The new area of the triangle is of 30 cm².

Jan and Dinah both ran for 20 seconds, each at a constant speed. Jan ran 50 mefers and Dingh ran 60 meters. 1. Who was moving faster? Explain how you know. 2. How far did each person move in 1 second?
Answers
By calculating speed of each person we can find who is faster.
What is Speed?Speed can be defined as the distance covered with respect to time. It is a scalar quantity. It is calculated as follows
Speed = Distance / Time taken
The time taken by each person is 20 seconds.
Distance covered by Jan = 50 meter
Speed of Jan = Distance / Time taken
Speed of Jan = 50 / 20
Speed of Jan = 2.5 meters per second
Distance covered by Dingh = 60 meter
Speed of Dingh = Distance / Time taken
Speed of Dingh = 60 / 20
Speed of Dingh = 3 meters per second
Since the speed of Dingh is more than Jan, we can say that Dingh is faster.
Distance = Speed × Time taken
Here, time taken = 1 second
This implies Distance Covered = Speed
Therefore, Jan covers 2.5 meters in one second while Dingh covers 3 meters in one second.

Write a coordinate proof to prove that Δ A B C is an isosceles triangle if the vertices are A(0,0), B(a, b) , and C(2 a, 0) .
Answers
An isosceles triangle is one with two equal-length sides. ΔABC is an isosceles triangle.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²] units.
Given that the coordinates of the vertices of the triangle are A(0,0), B(a, b), and C(2a, 0). Now, to prove that the given triangle is an isosceles triangle we need to find the length of each side of the triangle.
AB = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(a - 0)² + (b - 0)²]
= √(a² + b²)
BC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - a)² + (0 - b)²]
= √(a² + b²)
AC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - 0)² + (0 - 0)²]
= √4a²
= 2a
Since the length AB and BC are the same, while the length of AC is different, therefore, ΔABC is an isosceles triangle.

The geometric mean of a number and four times the number is 22 . What is the number?
Answers
If 22 is the geometric mean of a number and four times the number, then the number is 11.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Let x = x1 = unknown number
y = x2 = four times the number = 4x
Using the formula in solving geometric mean, plug in the values and variables.
GM = n√x1 x2 . . . xn
22 = √xy
22 = √x(4x)
22 = √4x^2
22 = 2x
x = 11
y = 4x
y = 44
Hence, the number is 11. 22 is the geometric mean of 11 and 44.

Write the equation of the circle that passes through the given point and has a center at the origin. (Hint: You can use the distance formula to find the radius.) (-2,3)
Answers
The equation of the circle that passes through the point (-2 , 3) and has a center at the origin is x^2 + y^2 = 13.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-2 , 3).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-2 - 0)^2 + (3 - 0)^2
radius= √4 + 9
radius = √13
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = √13

Two tents are in the shape of hemispheres, with circular floors. The ratio of their floor areas is 9: 12.25 . If the diameter of the smaller tent is 6 feet, what is the volume of the larger tent? Round to the nearest tenth.
Answers
The volume of the larger tent in the shape of hemispheres, with circular floors, is 89.8 cubic feet.
If the diameter of the smaller tent is 6 feet, then its radius is 3 feet. Solving for the area of its circular floor,
A = πr^2
A = π(3 feet)^2
A = 9π square feet
Using the ratio of the floor areas of the two tents, calculate the area of the circular floor of the larger tent.
9 : 12.25 = 9π square feet : x
where x = area of the circular floor of the larger tent
9x = 12.25(9π)
x = 12.25 π square feet
If the area of the circular floor of the larger tent is 12.25 π square feet, then solving for its radius,
A = πr^2
12.25 π square feet = πr^2
r = 3.5 feet
Hemisphere refers to half of a sphere and its volume is given by the formula V = 2/3πr^3, where r is the radius.
V = 2/3πr^3
V = 2/3 π (3.5 feet)^3
V = 89.79719002 cubic feet
