The surface area of the triangular prism is approximately 44.29 square millimeters.
What is surface area?
Surface area is the total area that the surface of a three-dimensional object covers. It is a measure of the amount of space that the surface of an object occupies. Surface area is usually measured in square units such as square meters, square centimeters, square inches, or square feet.
What is the area?
The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area.
The area of a plane figure is the space enclosed by its boundary.
According to the given information:
To find the surface area of a triangular prism, we need to add up the area of all the faces. A triangular prism has three rectangular faces and two triangular faces.
Let's start by finding the area of the triangular faces. The base of the triangular prism is a right triangle with base 4 millimeters, height 4 millimeters, and hypotenuse 5.7 millimeters. We can use the Pythagorean theorem to find the missing side:
[tex]a^2 + b^2 = c^2\\4^2 + 4^2 = 5.7^2[/tex]
16 + 16 = 32.49
32 = 32.49 - 0.49
32 = 32
So the missing side has length [tex]\sqrt{(5.7^2 - 4^2)} =3.69 millimeters.[/tex] This is the base of each triangular face.
The height of the triangular prism is 3 millimeters, so the height of each triangular face is also 3 millimeters.
The area of each triangular face is:
(1/2) × base × height
= (1/2) × 3.69 × 3
≈ 5.54 square millimeters
So the total area of the two triangular faces is:
2 × 5.54= 11.08 square millimeters
Now let's find the area of each rectangular face. The length of each rectangular face is the same as the base of the triangular face, which is 3.69 millimeters. The width of each rectangular face is the height of the triangular prism, which is 3 millimeters.
The area of each rectangular face is:
length × width
= 3.69 × 3
≈ 11.07 square millimeters
So the total area of the three rectangular faces is:
3 × 11.07
= 33.21 square millimeters
To find the surface area of the triangular prism, we add up the area of all five faces:
11.08 + 33.21
= 44.29 square millimeters
Therefore, the surface area of the triangular prism is approximately 44.29 square millimeters.

Express all real numbers greater than 2 in interval notation
The interval-notation for "all real-numbers" greater than 2 is (2, ∞).
The "Interval-Notation" is a way of expressing a set of real numbers using brackets to show which numbers are included in the set. In the case of all real numbers greater than 2, we can write this as:
(2, ∞)
The open-bracket "(" indicate that the number 2 is not included in the set, while the symbol "∞" represents all real numbers greater than 2.
This notation is used to express an open interval, meaning that the endpoints (in this case, 2 and infinity) are not included in the set.
Therefore, the required interval-notation is (2, ∞).

How to know number of bracelets madeIf Ava made an even number of bracelets using the 72 beads, then the total number of beads used in each bracelet must be an even number.
One way to check if the total number of beads used in each bracelet is even is to find out if the sum of the digits in the number 72 is even or odd. If the sum of the digits is even, then it is possible that Ava made an even number of bracelets. If the sum of the digits is odd, then it is not possible that Ava made an even number of bracelets.
The sum of the digits in 72 is 7 + 2 = 9, which is an odd number. Therefore, it is not possible for Ava to have made an even number of bracelets using the 72 beads, without dividing the beads.

An equation that models the trigonometric graph is:
y = 4 sin 4x
How to interpret the trigonometric graph?The general form for an equation that models a wave is this:
±a (sin/cos) (2π(x - p)/T)
where:
a is the amplitude
p is the phase shift
T is the period.
The ±ve will turn into +ve if the graph tends to start from the positive direction, and then turns -ve if it the graph tends to start from the negative direction.
The (sin/cos) will definitely become sine if the graph starts at 0 before it is being shifted. Then, it becomes cosine if the graph begins at the amplitude.
In this problem, we see that the graph begins as positive, and then at the amplitude with no phase shift, we see that the ±ve becomes +ve, (sin/cos) becomes sin, and p becomes zero. Plugging in the given values in the problem, we see that a = 4 and T = π/2.

8. A car wheel with a diameter of 18 inches spins at the rate of 10 revolutions per second. (i) What is the car's angular speed in radians per hour? (ii) What is the car’s linear speed in miles per hour?
Answer:
the car's angular speed is 72,000π radians per hour.
the car's linear speed is approximately 100.53 miles per hour.
Step-by-step explanation:
To find the car's angular speed in radians per hour, we can start by finding the angular speed in radians per second.
The formula for angular speed is:
ω = 2πf
where ω is the angular speed in radians per second, and f is the frequency or rate of rotation in revolutions per second.
In this case, the wheel is spinning at a rate of 10 revolutions per second, so:
ω = 2π(10) = 20π radians per second
To convert this to radians per hour, we can multiply by the number of seconds per hour:
20π radians per second × 3600 seconds per hour = 72,000π radians per hour
To find the car's linear speed in miles per hour, we can use the formula:
v = rω
where v is the linear speed, r is the radius of the wheel, and ω is the angular speed in radians per second.
The radius of the wheel is half the diameter, or 9 inches. To convert this to miles, we can divide by 12 and then by 5280:
9 inches ÷ 12 inches per foot ÷ 5280 feet per mile = 0.000142045 miles
Now we can substitute the values we have found:
v = (0.000142045 miles) × (18/2 inches) × (20π radians per second)
v ≈ 100.53 miles per hour
Answer:
(i) 10 revolutions = 10(2π) = 20π radians
10 revolutions/sec =
(20π radians/sec)(3,600 sec/hr) =
72,000π radians/hr
(ii) C = 18π inches
10 revolutions × 18π inches =
180π inches
(180π in./sec)(3,600 sec/hr) =
(648,000π in./hr)(1 mi./63,360 in.)
= 225π/22 miles/hour
= about 32.13 miles/hour

What is a proportional and non-proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other.
The difference between proportional and non-proportional linear relationships is that, although both have constant rates of change the proportional relationship has constant output to input ratios, and the non-proportional relationship does not.
In this problem, to determine the proportional relationship, we can also check for both values of x and y.
1. y = -0.75x + 5
When x = 1
y = -0.75(1) + 5
y = 4.25
when x = 2
y = -0.75(2) + 5
y = 3.5
The relationship is not proportional since as one variable increase, the other decreases.
2. y = 4x - 1
When x = 1
y = 4(1) - 1
y = 4 - 1
y = 3
when x = 2
y = 4(2) - 1
y = 8 - 1
y = 7
This relationship is proportional since the variables increases or decreases with one another.
3. y = (3/4)x

Polynomial Functions
a) Yes, the function is in standard form.
Degree = 2
Exponent = 2
Constant term = -1
b) No, the function is not in standard form.
And it doesn't have the degree, exponent and constant term.
Firstly, let's consider the function f(x) = x(x-1). To determine if it is a polynomial function, we need to check if all of its terms have non-negative integer exponents. In this case, we see that f(x) can be written as x² - x, which has only two terms, and each term has a non-negative integer exponent. Therefore, f(x) is a polynomial function.
In this case, the degree of f(x) is 2 because the highest exponent of x is 2.
In this case, the leading term of f(x) is x², and its leading coefficient is 1.
Finally, the constant term is the term that does not have the variable in it. Here, the constant term of f(x) is -1.
Next, let's consider the function f(x) = 3 - 1/2 x. We can see that f(x) is not a polynomial function because it has a term with a negative exponent.
Polynomial functions must have non-negative integer exponents on all terms.
Therefore, the answer to the first question is 'no.'
Since f(x) is not a polynomial function, it does not have a degree, leading term, or constant term.
