In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse.
If b = 5.4 yards and c = 7.5 yards, what is the perimeter? If necessary, round to the nearest
tenth.
The perimeter of the triangle would be 18.1 yards.
What is Pythagorean theorem ?
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between the three sides of a right triangle in Euclidean geometry. It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.
Given the information in the problem, we can use the Pythagorean theorem to find the length of the other leg, a:
[tex]c^2 = a^2 + b^2\\\\7.5^2 = a^2 + 5.4^2\\\\56.25 = a^2 + 29.16\\\\56.25 - 29.16 = a^2\\\\27.09 = a^2\\\\a = \sqrt{27.09} \\\\a = 5.2\ yards[/tex]
The perimeter of the triangle is the sum of the lengths of all its sides:
Perimeter = a + b + c
Perimeter = 5.2 + 5.4 + 7.5
Perimeter = 18.1 yards (rounded to the nearest tenth)
Therefore, The perimeter of the triangle would be 18.1 yards.

What are all values of x for which the function f defined by f(x) = (x2 - 3)e-x is increasing?.
The function f is increasing for x > 3/2.
To determine the values of x for which the function f is increasing, we need to find the critical points of f, which are the values of x where the function changes from increasing to decreasing or vice versa.
The first step is to find the derivative of f:
f'(x) = (2x - 3)e-x
Next, we need to find the critical points by setting f'(x) = 0 and solving for x:
(2x - 3)e-x = 0
2x - 3 = 0
x = 3/2
This is the only critical point of f. To determine the behavior of f near this critical point, we need to find the second derivative of f:
f''(x) = (2 - 3e-x)
For x < 3/2, f''(x) < 0, which means f is concave down and f'(x) is decreasing. This means that f is decreasing for x < 3/2.
For x > 3/2, f''(x) > 0, which means f is concave up and f'(x) is increasing. This means that f is increasing for x > 3/2.

The perimeter of square ABCD is 8 [tex]\sqrt{13}[/tex] units.
Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)
A square's perimeter is equal to the sum of its four sides or the product of four and one of its sides.
Therefore, the square's perimeter is equal to a + b + c + d.
4 × any of the sides because the sides of a square are equal to one another.
Since ABCD is a square:
Perimeter of a square = 4 × (length of a side)
=4 × AB
Formula to calculate the distance between two points [tex]$\left(x_1, y_1\right)$[/tex] and [tex]$\left(x_2, y_2\right)$[/tex] is, [tex]$\mathrm{d}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$[/tex]
Therefore, distance between two points A(-2, 1) and B(2, 7) will be,
AB = [tex]\sqrt{(2+2)^2+(7-1)^2} \\[/tex]
AB = [tex]\sqrt{4^2+6^2} \\[/tex]
AB = [tex]\sqrt{52} \\[/tex]
AB = 2[tex]\sqrt{13}[/tex]
Hence the perimeter of square ABCD can be calculated as 4 × AB
Now Perimeter of a square ABCD = 4 × 2[tex]\sqrt{13}[/tex]

Z is a vector space over F with the operations(v1, w1)+(v2, w2)=(v1 + v2, w1 + w2) and c(v1, w1)=(cv1, cw1) is proved.
A vector is a mathematical object that can be added and multiplied by a number, also known as a scalar.
In this case, we have two vector spaces, V and W, which are sets of vectors that can be added and scaled in a certain way, with the scalars taken from a field F.
=> (v1, w1)+(v2, w2)=(v1 + v2, w1 + w2)
We then define a new set, Z, which consists of ordered pairs of vectors, one from V and one from W. With the operations of adding two vectors element-wise and scaling a vector by a scalar, we can show that Z is also a vector space over F.
=> c(v1, w1)=(cv1, cw1).
To do this, we need to verify that Z satisfies the properties of a vector space, such as closure under addition and scalar multiplication, associativity and commutativity of addition, the existence of an additive identity and inverse, and distributivity of scalar multiplication over vector addition.

Limit, (4 + b)² - 8², Algebraically Determining Limits, h approaches 0, Expansion Formula for Square, Lim [(4 + b + h)² - 8² = (4 + b)² - 64.
To algebraically determine the limit, we can use the definition of a limit.
The limit of (4 + b)²-8² as h approaches 0 is equal to the limit of (4 + b + h)² - 8² as h approaches 0 minus (4 + b)² - 8².
Using the expansion formula for a square, we can write:
(4 + b + h)² - 8² = (4 + b)² + 2(4 + b)h + h² - 64
Now, taking the limit as h approaches 0:
lim [(4 + b + h)² - 8²] = lim [ (4 + b)² + 2(4 + b)h + h² - 64 ] = (4 + b)² - 64
So,
lim (4 + b)² - 8² as h approaches 0 = lim [(4 + b + h)² - 8²] - (4 + b)² + 64 = lim [(4 + b + h)² - 8²]
Hence,
lim (4 + b)² - 8² as h approaches 0 = lim [(4 + b + h)² - 8² = (4 + b)² - 64.

What is another way to write the expression x(14 + 19) + 30
Answer:
The answer could be x * 33 + 30.
Step-by-step explanation:
In this expression, the parentheses indicate that 14 and 19 are to be added together first, which equals 33. The expression x * 33 means that 33 is being multiplied by x. Finally, 30 is being added to this product. So both expressions represent the same mathematical operation.
Here's how to check our answer:
First, we simplify the expression inside the parentheses:
x(33) + 30
Next, we multiply x and 33:
x * 33 + 30
Finally, we add 30 to the product of x and 33:
x * 33 + 30
So, the expression x * 33 + 30 is equivalent to the expression x(14 + 19) + 30.

The variance is calculated by first finding the difference between each value in the dataset and the mean, squaring these differences, and then averaging the squared differences.
The result is a non-negative number that indicates how far, on average, each value deviates from the mean. If the variance is small, it means that most of the values are close to the mean, while a large variance indicates that the values are widely spread out.
One important use of variance is in statistical inference, where it is used to make predictions about a population based on a sample of data. Variance also plays a role in hypothesis testing, where it is used to determine whether the differences between two sets of data are statistically significant.

A hemisphere fits snugly inside a cylinder with a radius of 8 cm. A cone fits snugly inside the same hemisphere.
a. What is the volume of the cylinder?
b. What is the volume of the cone?
c. Estimate the volume of the hemisphere by calculating the average of the volumes of the cylinder and cone.
Answer:
guys i have no idea
Step-by-step explanation:
The volumes of the cylinder, the cone and the hemisphere are 512π cm³, 170.6π cm³ and 341.3π cm³ respectively.
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
Given that, a hemisphere fits snugly inside a cylinder with a radius of 8 cm. A cone fits snugly inside the same hemisphere.
Since, all of them are tightly packed in one another therefore, radius of all them will be equal,
And, and the radius of the cylinder is 6 cm, the radius of the hemisphere equals the radius of the cylinder. Also, the height of the cylinder equals the radius of the hemisphere.
r = radius of cylinder = 8 cm and
h = height of cylinder = radius of hemisphere = 8 cm
We know that,
Volume of a cylinder = π × radius² × height
Volume of a cone = 1/3 × π × radius² × height
Therefore,
a) The volume of cylinder =
π × 8² × 8 = 512π cm³
b) The volume of cone =
1/3 × π × 8² × 8 = 170.6π cm³
c) Volume of the hemisphere = (512π + 170.6π) / 2
= 341.3π cm³
Hence, the volumes of the cylinder, the cone and the hemisphere are 512π cm³, 170.6π cm³ and 341.3π cm³ respectively.

1. After 32 minutes the two pools will have the same amount of water.
2. 2,280 liters of water will be in each pool when they have the same amount.
Let's call the time in minutes when the two pools have the same amount of water "t". Getting into variables here.
At time t, the first pool will have 1272 + 31.5t liters of water, and the second pool will have 1600 + 21.25t liters of water.
For the two pools to have the same amount of water, we need:
1272 + 31.5t = 1600 + 21.25t
10.25t = 328
t = 32 minutes
I underlined all the answers if you don't want to read the entire thing, lol.
Question 1: So, 32 minutes after starting, the two pools will have the same amount of water.
Question 2: The amount of water in each pool will be:
1272 + 31.5 * 32 = 1600 + 21.25 * 32 = 1600 + 680 = 2,280 liters.
