The surface area of the triangular prism is 672 square millimeters.
what is surface area ?
Surface area is a metric used to determine how much overall space an object occupies. the total volume of the area of surface of a three-dimensional shape. The term "surface area" refers to a three-dimensional shape's entire surface area.
The triangular base has a height of 7 mm and a base of 24 mm, so its area is:
[tex]1/2 * base * height = 1/2 * 24 \ mm * 7\ mm = 84 \ mm^2[/tex]
There are two identical triangular faces, so their combined area is:
[tex]2 * 84 \ mm^2 = 168\ mm^2[/tex]
The three rectangular faces are all the same size, with a length of 24 mm and a height of 7 mm, so the area of each is:
[tex]length * height = 24 \ mm * 7 \ mm = 168 \ mm^2[/tex]
There are three rectangular faces, so their combined area is:
[tex]3 * 168\ mm^2 = 504\ mm^2[/tex]
To find the total surface area, we add the area of the two triangular faces to the area of the three rectangular faces:
[tex]168 \ mm^2 + 504 \ mm^2 = 672 \ mm^2[/tex]
Therefore, the surface area of the triangular prism is 672 square millimeters.

lo. Rebecca found the length and width of the 6. garage door. She used the measurements to find the perimeter of the garage door. Which of the following could be the perimeter of Rebecca's garage door? F 48 square feet /G 48 square inches/ H 48 feet/ J 48 cubic feet
H 48 feet could be the perimeter of Rebecca's garage door.
We know,
Perimeter is the distance around a two-dimensional shape. It is measured in units of length, such as feet or inches.
Rebecca found the length and width of the garage door, which are both measurements of length. Let's say she found that the length was 8 feet and the width was 6 feet.
To find the perimeter, she would add up the lengths of all four sides of the rectangle:
Perimeter = 2(length) + 2(width)
Perimeter = 2(8 feet) + 2(6 feet)
Perimeter = 16 feet + 12 feet
Perimeter = 28 feet
So the perimeter of Rebecca's garage door is 28 feet. None of the answer choices given match this value exactly, but H 48 feet is a possible perimeter if the garage door was much larger than the example given above. However, it is important to note that the term "cubic feet" (answer choice J) does not apply to perimeter, as cubic feet is a unit of volume and not length.

What is quotient rule ?The quotient rule is a formula used in calculus to find the derivative of a function that is the quotient of two other functions. Specifically, it gives the formula for finding the derivative of a function of the form f(x) = g(x) / h(x), where g(x) and h(x) are both functions of x.
We can use the quotient rule to find the derivative of h(x):
h(x) = (x+2)/(x-2)
h'(x) = [ (x-2)(1) - (x+2)(1) ] / (x-2)^2 (apply quotient rule)
Simplifying the numerator, we get:
h'(x) = [ x-2 - x-2 ] / (x-2)^2
h'(x) = -4 / (x-2)^2

m + 2(m + 1) = 14 {4}
The supplied value of 4 is a solution to the equation m + 2(m + 1) = 14.
Is the supplied value a solution or not?Given the equation in the question;
m + 2(m + 1) = 14

Find the least common multiple (LCM) of 24 and 6.
To find the LCM of 24 and 6, we can use the prime factorization method.
First, we find the prime factorization of each number:
24 = 2 x 2 x 2 x 3
6 = 2 x 3
Then, we identify the highest power of each prime factor that appears in either number.
The prime factor 2 appears three times in 24, but only once in 6. Therefore, we take the highest power of 2, which is 2 x 2 x 2 = 8.
The prime factor 3 appears once in both numbers, so we take the highest power of 3, which is 3.
Finally, we multiply these together to get the LCM:
LCM(24, 6) = 8 x 3 = 24
Therefore, the LCM of 24 and 6 is 24.

The amount Troy charges to mow a lawn is proportional to the time it takes him to mow the lawn. Troy charges 30 to mow a lawn that took him 1.5 hours to mow.
Which equation models the amount in dollars, d, Troy charges when it takes him h hours to mow a lawn?
The amount Troy (D, in dollars) charges to mow a lawn is proportional to the time (H, in hours) it takes him to mow the lawn.
Hence, we can write [tex]\text{D = kH}[/tex] ......... (1), where k is a constant.
Now, given that Troy charges $30 to mow a lawn that took him 1.5 hours to mow.
So, from equation (1) we get
[tex]{30 = 1.5\text{k}[/tex]
[tex]\rightarrow \text{k = 20}[/tex].

Find the area of the indicated region. We suggest you graph the curves to check whether one is above the other or whether they cross, and that you use technology to check your answer. Between y = x2 − 4x + 1 and y = −x2 + 4x − 5 for x in [0, 3]
The areas of the region between the curves is -40/3square units.
We must first graph the curves in order to identify which one is on top in order to calculate the area of the region bounded by the curves for x in [0, 3]. y = x²− 4x + 1 and y = −x²+ 4x − 5
The vertex of the graph of y = x²− 4x + 1is at (2, -3), and it opens upward. The vertex of the graph of y =−x²+ 4x − 5 is at (2, -1), and it opens downward.
Thus, the curve y = x²− 4x + 1 is on top for x in [0, 1], and the curve y = −x²+ 4x − 5 is on top for x in [1, 3].
To determine which curve is on top, we can set them equal to each other and solve for x:
x²− 4x + 1 = −x²+ 4x − 5
2x² - 8x + 6 = 0
x² - 4x + 3 = 0
(x - 3)(x - 1) = 0
x = 1 or x = 3
Thus, the curves cross at x = 1 and x = 3. To find which curve is on top between these two points, we can test a point in between, such as x = 2:
y = x²− 4x + 1 = 1
y = −x²+ 4x − 5 = -1
Using integration, we can find the area of the region:
∫[0,1] (x²− 4x + 1) dx + ∫[1,3] (−x²+ 4x − 5) dx
= [(1/3)x³ - 2x² + x] from 0 to 1 + [(-1/3)x³ + 2x² - 5x] from 1 to 3
=[1/3-2+1]+[{-9+8-15}-{-1/3+2-5}]

An initial amount of $1200 is invested into an account earning 4.25% interest compounded annually.
Q1.1 Part a)
Write the equation for the amount of money in the account after t years. Hint: "compounded annually" means that the money will be compounded one time per year.
Q1.2 Part b)
How long will it be until the amount of money in the account reaches $3000 (use a logarithm to find the exact amount of time, and then round your answer to 2 decimal places)?
Q2 Logarithmic Functions
According to the CDC, the relationship between the median weight of a female child and the age of a female child (from 0 to 36 months) can be modeled approximately by W=7.5+5.9ln(M+1), where
M is the age in months and W is the median weight in pounds.
Q2.1
Graph this function in an appropriate window. Make sure to label axes, scale, and all important features of the graph.
Q2.2
Determine W ^−1(28). What does this mean in the given context?
This means that the median weight of a female child at 31.48 months is 28 pounds (approximately) base on logarithmic function.
Logarithmic function calculation.
Q1.1: The equation for the amount of money in the account after t years, compounded annually, can be given by:
A = P(1 + r/100)^t
where A is the amount of money in the account after t years, P is the principal amount invested, r is the annual interest rate, and t is the number of years.
Plugging in the values given in the problem, we get:
A = 1200(1 + 4.25/100)^t
Q1.2: We need to solve for t in the equation:
3000 = 1200(1 + 4.25/100)^t
Dividing both sides by 1200, we get:
2.5 = (1 + 4.25/100)^t
Taking the natural logarithm of both sides, we get:
ln 2.5 = t ln (1 + 4.25/100)
Solving for t, we get:
t = ln 2.5 / ln (1 + 4.25/100) ≈ 15.91 years
So, it will take approximately 15.91 years for the amount of money in the account to reach $3000.
Q2.1: To graph the function W = 7.5 + 5.9 ln(M + 1), we can use a graphing calculator or software. Here is a possible graph:
Graph of W = 7.5 + 5.9 ln(M + 1)
Q2.2: To find W ^−1(28), we need to solve the equation:
28 = 7.5 + 5.9 ln(M + 1)
Subtracting 7.5 from both sides, we get:
20.5 = 5.9 ln(M + 1)
Dividing both sides by 5.9, we get:
ln(M + 1) ≈ 3.474576
Taking the inverse logarithm of both sides, we get:
M + 1 ≈ e^3.474576
M ≈ e^3.474576 - 1 ≈ 31.48 months
So, W ^−1(28) ≈ 31.48 months. This means that the median weight of a female child at 31.48 months is 28 pounds (approximately).
