To find the surface area you need to find the area of each face and add them together

2 (W L+H L+H W) = surface area  

2·(4·7+3·7+3·4)=122

Answer:

Step-by-step explanation:

Given dimensions of the rectangular prism ,

4"×3"×7"

We know, Total surface area of a cuboid= 2(lb+bh+hl)

where, l=length of the cuboid

 b= breadth " " "

 h= height " " "

Since, a rectangular prism holds the shape of a cuboid, therefore it's surface area should also be 2(lb+bh+hl)

Now, surface area of the rectangular prism = 2(4×3+3×7+7×4)

 =2(12+21+28)

 =2×61

 =122 square inches.

The ladder reaches the height of approximately 16.03 feet up the wall. (Rounded to the nearest hundredth of a foot)

We can use trigonometry to solve this problem. Let h be the height up the wall that the ladder reaches, and let θ be the angle that the ladder makes with the ground. We know that the length of the ladder (hypotenuse) is 16 feet and the angle θ is 78 degrees.

We can use the trigonometric function tangent (tan) to find the height h:

tan(θ) = opposite/adjacent

In this case, the opposite side is the height h, the adjacent side is the distance from the ladder to the wall (which is the same as the distance from the wall to Lauren), and the angle θ is 78 degrees. So we have:

tan(78°) = h/x

where x is the distance from the ladder to the wall. Solving for h, we get:

h = x * tan(78°)

We don't know the value of x, but we can use the fact that the ladder is 16 feet long to find it. Using the Pythagorean theorem, we have:

x^2 + h^2 = 16^2

Substituting h = x * tan(78°), we get:

x^2 + (x * tan(78°))^2 = 16^2

Simplifying, we get:

x = 16 / √(1 + tan^2(78°))

x ≈ 3.83 feet

Finally, we can substitute x into our equation for h:

h = x * tan(78°)

h ≈ 16.03 feet

Therefore, the ladder reaches approximately 16.03 feet up the wall. Rounded to the nearest hundredth of a foot, the answer is 16.03 feet.

6. f(x)g(x)+h(x) = 20x3-4x. This answer is arrived at by using the rules of algebra and the values of the given functions.

7. f(x)g(x) = -15x2 - 18x - 15

Polynomials are algebraic expressions consisting of variables and coefficients that are combined through addition, subtraction, multiplication and division operations. For example, the polynomial 4x² + 3x - 5 can be written as the sum of 4x², 3x and -5.

6. In order to calculate f(x) g(x)+h(x), it is necessary to first multiply f(x) and g(x). Since f(x)=4x and g(x) = 5x2-4, it follows that f(x)g(x)=20x3-4x. Next, it is necessary to add h(x) to this product. Since h(x) = 9x, it follows that f(x)g(x)+h(x) = 20x3-4x+9x = 20x3-4x. Since each coefficient is correctly represented in the answer, it follows that the correct answer is 20x3-4x.

Multiplying f(x) and g(x) gives the product of 20x3-4x, and adding h(x) to this product gives the sum of 20x3-4x. As each coefficient is correctly represented in the answer, the correct answer is 20x3-4x.

7. The product of two polynomials is found by multiplying each term of one polynomial by each term of the other polynomial. This is known as the FOIL method (First, Outer, Inner, Last).

The first term is the product of the first terms of each polynomial, which is 3x x 4x = 12x2.

The second term is the product of the outer terms, which is 3x x -5x = -15x2.

The third term is the product of the inner terms, which is 5 x -5x = -25x.

Finally, the fourth term is the product of the last terms of each polynomial, which is 5 x -3 = -15.

We can now combine the terms to get the product of the two polynomials, which is:

f(x)g(x) = -15x2 - 18x - 15.

Therefore, the correct coefficient for each term is -15x2 for the first term, -18x for the second term, and -15 for the third term.

To enlarge Shape A by a scale factor of 1.5 with the center of enlargement (0, 0), we have to multiply every length by 1.5.

Enlargement of Shape A

Enlargement of a shape is when it is either stretched or shrunk in one or both directions. The original shape is called the pre-image, while the new shape is called the image. What is the centre of enlargement?

The center of an enlargement is the point about which all of the points of the pre-image are scaled to obtain the image. When the scale factor is greater than 1, the image of the pre-image is an enlargement. When the scale factor is between 0 and 1, the image of the pre-image is a reduction.In an enlargement, each point on the pre-image is mapped onto a corresponding point on the image along a straight line which goes through the centre of enlargement.

The new shape has a larger size than the original shape. To expand shape A by a scale factor of 1.5, you need to multiply each length by 1.5. You have to create new points. It's easy to use a scale ruler to make sure each length is multiplied by 1.5.

A Centre of enlargement is a point in the coordinate plane that enlarges or shrinks a figure by some scale factor. In the problem, the center of enlargement is (0, 0).

Thus, we have to extend every length of Shape A by 1.5, and our scale factor is 1.5. We get Shape B by doing so. Now, we can conclude that to enlarge Shape A by a scale factor of 1.5 with the center of enlargement (0, 0), we have to multiply every length by 1.5.

Step-by-step explanation:

There are 1960 different ways to distribute 8 identical pieces of candy to the five children, where the twins get an equal amount of candy.

First, distribute the candy to the twins.

Split the 8 pieces of candy into two equal parts for the twins using combinations:

C(8, 4)

This means selecting 4 pieces of candy from the 8 identical pieces for one twin, and the remaining 4 pieces will automatically go to the other twin.

C(8, 4) is calculated as:

[tex]^8C_4 = \dfrac{8!}{4!(8-4)!}[/tex]

     = 8! / (4! * 4!)

     = (8 * 7 * 6 * 5) / (4 * 3 * 2 * 1)

     = 70

Now, you have distributed 4 pieces of candy to each of the twins. Y

In this case, you have 6 pieces of candy to distribute among 3 children, and you can use two dividers (bars) to separate the candy for each child.

This can be represented as:

OO|OO|OO

The two bars split the 6 pieces of candy into three sections for the three children.

So, you have C(6 + 2, 2) ways to distribute the remaining candy:

[tex]^{6+2}C_2 = \dfrac{8!}{2!(8-2)!}[/tex]

         = 8! / (2!(8 - 2)!)

         = 8! / (2! * 6!)

         = (8 * 7) / (2 * 1)

         = 28

Now, the total number of ways to distribute the candy

Total ways = C(8, 4) * C(8, 2) = 70 * 28 = 1960

The equation representing the situation is 4x = y - 1, where x is the number of households with one pet and y is the total number of households. This can be answered by the concept of Simple equation.

Let's assume that there are x households with a single pet. The number of households with no pets is given as one-fourth of the number of households with multiple pets, which means there are 4 times as many households with multiple pets as there are households with no pets. Let's represent the total number of households as y.

Therefore, we can say that the number of households with no pets is (y - x)/4, and the number of households with multiple pets is 3(y - x)/4 since there are 4 times as many households with multiple pets as there are households with no pets.

Now, we can use the given information that the number of households with no pets is one-fourth of the number of households with multiple pets to write the equation:

(y - x)/4 = x/3

Solving for y, we get:

y = 4x + 3x/4 = 16x/4 + 3x/4 = 19x/4

But we are given that the total number of households y includes the households with one pet, so we can write:

y = x + (y - x)/4 + 3(y - x)/4 = x + y/4

Substituting the value of y from the previous equation, we get:

19x/4 = x + 19x/16

Solving for x, we get:

x = 16/3

Therefore, the equation representing the situation is 4x = y - 1, where x = 16/3 and y = 19x/4, which simplifies to:

4(16/3) = y - 1

y = 21

Therefore, there are 16 households with one pet and 5 households without any pets.

What is trapezoid?

In geometry, a trapezoid is a four-sided polygon that has at least one pair of parallel sides. The parallel sides of a trapezoid are called bases, while the non-parallel sides are called legs.

The image below appears to be a trapezoid with vertices at A(2,2), B(4,5), C(6,5), and D(8,2). There are several ways to obtain this image, but here are two possible methods:

Method 1: Plotting the Points

One way to obtain the image is to plot the points A, B, C, and D on a coordinate plane, and then connect them in the correct order to form the trapezoid. Here are the steps:

Draw a coordinate plane with x and y axes.

Plot the point A at (2,2).

Plot the point B at (4,5).

Plot the point C at (6,5).

Plot the point D at (8,2).

Connect the points A, B, C, and D in the order ABDC to form the trapezoid.

Method 2: Transformations

Another way to obtain the image is to start with a reference trapezoid with known vertices, and then apply a sequence of transformations to obtain the desired trapezoid. Here are the steps:

Start with a reference trapezoid with vertices at (0,0), (2,3), (4,3), and (6,0). This trapezoid has the same shape as the desired trapezoid, but is located in a different position on the coordinate plane.

Translate the reference trapezoid 2 units to the right and 2 units up by adding (2,2) to each vertex. This results in a trapezoid with vertices at (2,2), (4,5), (6,5), and (8,2), which is the desired trapezoid.

(Optional) Rotate or reflect the trapezoid as desired to obtain different orientations or symmetries.

If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).

However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.

To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.

C(7,2) = 7!/(2!(7-2)!) = 21

So there are 21 possible plans, regardless of whether they meet the conditions or not.

Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.

Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.
