Answer:

The area of each of the bases will be m2 answer; (1)(3)=3

The area of the right and left lateral faces will be m2. answer; (1)(2)=2

The area of the front and back lateral faces will be m2. answer; (2)(3)=6

The lateral area of the prism will be m2. answer ; 16

Step-by-step explanation:

Area of each bases = 3 m²

Area of the right and left lateral faces = 2 m²

Area of the front and back lateral faces = 6 m²

Lateral area = 16 m²

Surface area of the rectangular prism = 22 m²

Lateral area = 2(l + w)h

Surfacea area = 2(wl+hl+hw)

We are given a rectangular prism that has the following dimensions:

Length (l) = 1 m

Width (w) = 3 m

Height (h) = 2 m

Area of each bases = l × w = 1 × 3 = 3 m²

Area of the right and left lateral faces = 1 × 2 = 2 m²

Area of the front and back lateral faces = 2 × 3 = 6 m²

Lateral area of the rectangular prism = 2(l + w)h = 2(1 + 3)2 = 16 m²

Surface area of the rectangular prism = 2(wl+hl+hw) = 2(3 × 1 + 2 × 1 + 2 × 3) = 22 m²

See the attached picture.

The given function f(x) = -3(x-2)^2 + 14 is a quadratic equation shown in vertex form. To find an equivalent equation in standard form or solve for its roots, one can expand and simplify or use the quadratic formula with the appropriate coefficients.

The equation f(x) = -3(x-2)^2 + 14 is a quadratic equation in vertex form. In standard form, a quadratic equation is represented as at^2 + bt + c = 0. To express f(x) in this standard form, we simply need to expand the squared term and simplify. The given equation already shows that the parabola has been reflected vertically due to the negative sign before the coefficient of the squared term, and it is shifted 2 units to the right and 14 units up from the origin.

Transformations of the independent variable such as multiplying by a constant or adding a number, like in f(2x) or f(-2x), will affect the graph of the quadratic function. They result in horizontal scaling or reflection, while transformations like f{-2(x+1)} involve horizontal shifting.

To solve a quadratic equation that is set equal to zero, we can use the quadratic formula, which employs the coefficients a, b, and c. As an example, for a quadratic equation with constants a = 4.90, b = 14.3, and c = -20.0, the roots can be found through this formula.

First simply the inside bracket using distributive property:

7(a + 2b)

7(a) + 7(2b)

7a + 14b

5(4a + 7a + 14b)

5(11a + 14b)

Use distributive property again

5(11a) + 5(14b)

55a + 70b

Answer:

x= -2

Step-by-step explanation:

An example could be

10 ( x+2) + 3(x+4) = 6(x+3)

Distribute

10x+20 +3x+12 = 6x+18

Combine like terms

13x +32 = 6x+18

Subtract 6x from each side

13x-6x +32 = 6x-6x+18

7x +32 = 18

Subtract 32 from each side

7x +32-32 = 18-32

7x =-14

Divide by 7

7x/7 = -14/7

Answer:

B

Step-by-step explanation:

The volume of a square pyramid can be found using:

v=1/3 bh

Where b is the area of the base, and h is the height

First, let's find the area of the base

a=l*l

We know the length is 5, so we can substitute it in

a=5*5

a=25

Now we know b(area), is 25, and we know the volume is 75, so we can substitute them in

v=1/3 bh

75=1/3(25)h

Divide both sides by 1/3, or multiply both sides by the reciprocal, 3/1

225=25h

Divide both sides by 25

h=9

So, the height is 9 feet , or choice B

Answer:

C - 9 cm

Step-by-step explanation:

We can use the Pythagorean theorem to figure out the missing side length, in this case, X.

The Pythagorean theorem states: a^2 + b^2 = c^2, with c being the hypotenuse. We have the side length of the hypotenuse which is 15, and we have another side length of 12. Let's put these back in our equation:

a^2 + 12^2 = 15^2;

If we simplify the squares by simply doing them: a^2 + 144 = 225;

Now let's subtract 144 from both sides to isolate the variable, a:

a^2 = 81;

Now we square both sides to find a:

a = 9

The missing side length is 9 cm.

2. -33x^7 + 10x^6  - 14x^5 + 4x^4 + 11x^2 - 5x + 32

Step-by-step explanation:

Problem 1.

How much greater is -20x^2 + 5x + 17 than -19x^2 + 20x + 18

Problem 1. Solution:

Subtract the second polynomial from the first polynomial.

-20x^2 + 5x + 17 - (-19x^2 + 20x + 18) =

To simplify the parentheses, think of the negative sign left of the parentheses as the number -1, and distribute it using the distributive property.

= -20x^2 + 5x + 17 -1(-19x^2 + 20x + 18)

We multiply -1 by each term in the parentheses.

= -20x^2 + 5x + 17 + 19x^2 - 20x - 18

Now we combine like terms. First, group each set of like terms together.

= -20x^2 + 19x^2 + 5x - 20x + 17 - 18

Now combine like terms.

= -x^2 - 15x - 1

Answer to Problem 1.: -x^2 - 15x - 1

Problem 2.

How much greater is -20x^7 + 10x^6 - 5x + 15 than 13x^7 + 14x^5 -4x^4 -11x^2 - 17

Problem 2. Solution:

Subtract the second polynomial from the first polynomial.

-20x^7 + 10x^6 - 5x + 15 - (13x^7 + 14x^5 - 4x^4 - 11x^2 - 17) =

To simplify the parentheses, think of the negative sign left of the parentheses as the number -1, and distribute it using the distributive property.

= -20x^7 + 10x^6 - 5x + 15 -1(13x^7 + 14x^5 - 4x^4 - 11x^2 - 17)

We multiply -1 by each term in the parentheses.

= -20x^7 + 10x^6 - 5x + 15 - 13x^7 - 14x^5 + 4x^4 + 11x^2 + 17

Now we combine like terms. First, group each set of like terms together.

= -20x^7 - 13x^7 + 10x^6 - 14x^5 + 4x^4 + 11x^2 - 5x + 15 + 17

Now combine like terms.

= -33x^7 + 10x^6  - 14x^5 + 4x^4 + 11x^2 - 5x + 32

98-76+54+3+21=100

Step-by-step explanation:

Possible Variants are:

[tex]98 - 76 + 54 + 3 + 21 = 100\\9 - 8 + 76 + 54 - 32 + 1 = 100\\98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100\\98 - 7 - 6 - 5 - 4 + 3 + 21 = 100\\9 - 8 + 76 - 5 + 4 + 3 + 21 = 100\\98 - 7 + 6 + 5 + 4 - 3 - 2 - 1 = 100\\98 + 7 - 6 + 5 - 4 + 3 - 2 - 1 = 100[/tex]

[tex]98 + 7 - 6 + 5 - 4 - 3 + 2 + 1 = 100\\98 - 7 + 6 + 5 - 4 + 3 - 2 + 1 = 100\\98 - 7 + 6 - 5 + 4 + 3 + 2 - 1 = 100\\98 + 7 - 6 - 5 + 4 + 3 - 2 + 1 = 100\\98 - 7 - 6 + 5 + 4 + 3 + 2 + 1 = 100\\9 + 8 + 76 + 5 + 4 - 3 + 2 - 1 = 100\\9 + 8 + 76 + 5 - 4 + 3 + 2 + 1 = 100\\9 - 8 + 7 + 65 - 4 + 32 - 1 = 100\\[/tex]

From:

98-76+54+3+21=100

The least number of plus and minuses needed to make 100 are 1 and 3 respectively.

The least number of pluses and minuses needed to arrange the numbers 9 8 7 6 5 4 3 2 1 to equal 100 is four. A valid combination resulting in 100 is 98 - 7 + 65 + 43 - 21 which uses two minuses and two pluses.

Your question asks how many pluses and minuses can be inserted in the string 9 8 7 6 5 4 3 2 1 without altering its order to make 100. An interesting mathematical challenge problem indeed!

Remember, this question pertains to arithmetic operations of addition (+) and subtraction (-). A possible solution can be 98 - 7 + 65 + 43 - 21. This results in 100 with four total operations interspersed (two minuses and two pluses).

By using the arithmetic operations strategically, the least number of pluses and minuses (total four) you need to yield 100 is produced. Hence, this combination of digits and operators achieve the intended sum balancing positive and negative values.

The area of Brian's cake's top = base x height

                                                  = 13 x 9

                                                  = 117 square inches

Area of Nancy's cake's top = [tex]\frac{1}{2\\}[/tex] x base x height

                                             = [tex]\frac{1}{2}[/tex] x 15 x 12

                                             = 6 x 15

                                             = 90 square inches

Therefore, Brian's cake's top has a greater area than Nancy's.

Answer:

Brian's parallelogram-shaped cake top had the greater area. It was 27 in² greater than Nancy's cake top.

Step-by-step explanation:

To find the area of a parallelogram, use the formula A = b × h, where A is the area, b is the base and h is the height. Substitute the base and height into the equation.

A = 13 × 9

Then work out the equation to get:

117 = 13 × 9

This means that Brian's cake top has an area of 117 in².

Next, find the area of a triangle using the formula A = [tex]\frac{bh}{2}[/tex], where A is the area, b is the base, and h is the height. Substitute the base and height into the equation.

A = [tex]\frac{15*12}{2}[/tex]

The * symbol means the same as multiply.

Then work out the equation to get:

180 = [tex]\frac{15*12}{2}[/tex]

This means that Nancy's cake top has an area of 90 in².

We can see that Brian's cake top has a greater area than Nancy's already, but to find out how much greater, just subtract 90 from 117:

117 - 90 = 27

Hence, Brian's cake top has a greater area of 27 in².

Let x represent Kim's age

"Bob is 4 years older than twice Kim's age"

Thus, Bob's age =

4 + 2x years

"Paul is 1 year younger than 3 times Kim's age."

Thus. Paul's age is

(3x - 1) years

If Bob's age and Paul's age is equal, we can write:

2x + 4 = 3x + (-1)

Thus, the required expression is

Option D)

The equation can be used to determine Kim’s age will be 2x + 4 = 3x + (–1). Then the correct option is D.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Use the information to write an equation with variables on both sides. Let x represent Kim’s age.

Bob is 4 years older than twice Kim’s age. Then the age of the Bob will be in terms of x.

B = 2x + 4

Paul is 1 year younger than 3 times Kim's age. Then the age of the Paul will be in terms of x.

P = 3x – 1

Bob and Paul are the same age.

B = P

Put the value of B and P, then we have the equation will be

2x + 4 = 3x – 1

2x + 4 = 3x + (–1)

Then the correct option is D.

Answer:

Last month

Step-by-step explanation:

Just look at the numbers.

The first number is (167.94 + 21.41) / 7 and the second number is (77.23 + 6.49) / 7. We see that they both have the denominator of 7, so we can just focus on comparing the numerators.

Look at 167.94 + 21.41. Clearly, 167.94 is bigger than 77.23 from the second number. We also see that 21.41 is clearly bigger than 6.49. If both numbers of the first number are bigger than both numbers from the second number, we know that the sum of the first two numbers will be bigger than the second sum.

Thus, the bigger the numerator, the bigger the amount paid, even including the dividing 7 at the end.
