Answer:

To find the perimeter of a regular pentagon, you need to know the length of one side and the number of sides. In a regular pentagon, all sides have the same length and the shape has 5 sides.

Let's say the length of one side of the regular pentagon is 's'.

The formula for the perimeter of a regular pentagon is:

Perimeter = 5s

This is because a regular pentagon has 5 sides of equal length, so you can simply add the length of each side together 5 times.

Therefore, the perimeter of a regular pentagon with a side length 's' is 5s.

Working backward, the number that Lara started with in performing the mathematical operations was 15.

We can use mathematical operations to determine the initial number that Lara started with.

Mathematical operations include addition, subtraction, division, multiplication, etc.

Let the number that Lara started with = x

x < 20

x ÷ 2 + 6 = y

y ÷ 3 = 4.5

y = 13.5 (4.5 x 3)

x ÷ 2 + 6 = 13.5

x ÷ 2 = 7.5

x = 15 (7.5 x 2)

Thus, Lara started performing the mathematical operations with 15 and got a final result of 4.5.

B) Wx is equal to WX.

When a shape is rotated 90 degrees, the length of its sides and angles do not change. Therefore, the length of Wx in the original trapezoid will be the same as the length of WX in the rotated trapezoid.

Note that given the factors above, Orr should replace the above plant. This has to do with depreciation and book value.

We need to first compute the current total cost of keeping the old plant.

Book value = $4,500,000 - $1,000,000/year x 4 years

= $500,000

Thi smean that the current total cost of keeping the old plan tfor the reamining 10 year is

Total cost of keeping old plant = $1,000,000/year x 10 years - $500,000 + $150,000

= $9 650 000

Now lets calculate the total cost of purchasing the new plant for 10 years.

$600,000 - $150,000

= $450,000 per year.

The salvage value after 10 years is $0.

Total cost of new plant = $3,500,000 + $450,000/year x 10 years = $8,000,000

Since the cost of keeping is higher than the new one, then Orr should get a new plant.

$9 650 000 > $8,000,000

Answer:

Step-by-step explanation:

The given expression is
[tex]\left(2x^2\:+\:23x\right)\:-\:\left(3x\:-\:18\right)[/tex]

and we are asked to factor it

Step 1
Remove parentheses
[tex]\left(2x^2\:+\:23x\right) = 2x^2 + 23x\\\\-\:\left(3x\:-\:18\right) = - (3x) - (-18) = -3x + 18\\\\[/tex]

Step 2
Add the individual terms to correspond to the original expression:
[tex]\left(2x^2\:+\:23x\right)\:-\:\left(3x\:-\:18\right) \\\\= 2x^2 + 23x -3x + 18\\\\= 2x^2 + 20x + 18[/tex]

Step 3
Factor out common term 2

[tex]2x^2+20x+18 \\\\= 2\left(x^2+10x+9\right)[/tex]

Step 4
Factor [tex]x^2+10x+9[/tex]

To do this find two numbers such that their sum = 10 and product = 9
We can easily see that these two numbers are 1 and 9 because 1 + 9 = 10 and 1 x 9 = 9

Therefore, splitting the expression into groups we get
[tex]x^2 + 10x + 9 = x^2 + 1x + 9x + 9\\\\[/tex]

Step 5

Factor:

[tex]x^2 + 1x = x(x+ 1)\\9x + 9 = 9(x + 1)\\\\[/tex]

Therefore
[tex]x^2 + 1x + 9x + 9 = x(x + 1) + 9(x + 1)\\\\[/tex]

Step 6

Factor common term (x + 1) from the expression
[tex]x(x + 1) + 9(x + 1) = (x + 1)(x + 9)[/tex]

Step 7
Putting it all together
Remember we factored out the 2 in step 3 so we got to put it back into the factored expression giving the final factored expression as

[tex]2 (x + 1)(x + 9)[/tex]

If Frank spends $90 on his $1800 monthly income, then 95 percent of monthly check does not go toward food.

Let's say Frank spends $90 on food and has a monthly income of $1800. We can calculate the percentage of his monthly check that does not go towards food as follows:

Percentage = (Total Income - Food Expenses) / Total Income

Percentage = (1800 - 90) / 1800

Percentage = 0.95 = 95%

Therefore, 95% of Frank's monthly check does not go towards food.

Here are the steps in detail:

Subtract the food expenses from the total income to get the amount of money that is not spent on food.

Divide the amount of money that is not spent on food by the total income to get the percentage.

In this case, the amount of money that is not spent on food is $1800 - $90 = $1710. The percentage of the monthly check that is not spent on food is $1710 / $1800 = 0.95 = 95%.

Part A) The vertex of the graph of the function, (t, h(t)) is (2, 68).

Part B) The t-coordinate of the vertex represent is the time it takes for the ball to reach its maximum height (option b)

Part C) The h(t)-coordinate of the vertex represent is the ball's maximum height (option a).

Part A asks for the vertex of the graph of the function, which is the point where the function reaches its maximum or minimum value. To find the vertex of a quadratic function like

=> h(t) = 4 + 64t – 16t²,

we can use the formula

=>  t = -b/2a,

where a, b, and c are the coefficients of the quadratic equation ax² + bx + c and t is the input variable (in this case, the time).

The t-coordinate of the vertex is simply the value we get when we plug this formula into our equation.

So, for

=> h(t) = 4 + 64t – 16t²,

we have a = -16, b = 64, and c = 4.

Plugging these values into the formula

=> t = -b/2a,

we get

=> t = -64/(2*(-16)) = 2.

The t-coordinate of the vertex is therefore 2.

To find the h(t)-coordinate of the vertex, we can simply plug t = 2 into the function h(t) = 4 + 64t – 16t² and evaluate it.

This gives us

=> h(2) = 4 + 64(2) – 16(2²) = 68.

Therefore, the vertex of the graph of h(t) is (2, 68).

Part B asks what the t-coordinate of the vertex represents. We know that the t-coordinate is the time at which the ball reaches its maximum height.

Therefore, the correct answer is B: the time it takes for the ball to reach its maximum height.

Part C asks what the h(t)-coordinate of the vertex represents. We just found that the h(t)-coordinate of the vertex is the maximum height of the ball.

Therefore, the correct answer is A: the ball's maximum height.

Step-by-step explanation:

As we used the distributive property of multiplication to rewrite 7+21 as a product of 7 x (1+3) or 7 x 4.

However, you are asked to express this sum as a product of two factors. A factor is a number that is multiplied by another number to produce a product. Therefore, to express 7+21 as a product of two factors, we need to find two numbers that, when multiplied together, give us the sum of 7+21.

One way to approach this problem is to use the distributive property of multiplication, which states that a(b+c) = ab + ac. We can apply this property by rewriting 7+21 as 7+3*7, since 21 is equal to 3 times 7. Then, we can factor out the common factor of 7 from the expression to get:

7+37 = 7(1+3)

Now, we have expressed 7+21 as a product of two factors: 7 and (1+3), or simply 7 and 4. Therefore, the expression that shows 7+21 written as a product of two factors is:

Therefore, the customer saved $2,448.45.

Step-by-step explanation:

To answer this question, we need to use the percentage discount formula to find the original price and the amount saved.

Let x be the original price of the product. Then, after applying the 12% discount, the price becomes 0.88x. If the total is over $10,000 after this discount, then an additional 3% discount is applied on the remaining balance, which means the final price becomes 0.97 * 0.88x.

We are given that the final price is $13,500, so we can set up an equation and solve for x:

0.97 * 0.88x = 13,500 x = 13,500 / (0.97 * 0.88) x = 15,948.45

Therefore, the original price was $15,948.45.

The amount saved is the difference between the original price and the final price:

Solving for x in each case, we get:

2x-8 = 4: 2x = 12 → x = 6

2x-8 = -4: 2x = 4 → x = 2

So the zeros of the equation are x=6 and x=2. The distance between them is:

In triangle ACE, with BD parallel to CE, using similar triangles and ratios, we get a quadratic equation with two possible solutions. Only the positive one is chosen, so AC is approximately 30.96 units long.

Since BD is parallel to CE, we can use the property of similar triangles to find the length of AC.

Triangles ABD and ACE are similar because they have the same corresponding angles. This means that the ratios of their corresponding side lengths are equal.

We know that AB = 10, AD = 16, and DE = 22.

Let x be the length of AC. Then, we have

AB/AD = CE/EA (by similarity of triangles ABD and ACE)

10/16 = CE/(x-16+22) (substituting CE = EA - DE and simplifying)

5/8 = CE/(x-6)

CE = (5/8)(x-6)

We also know that

BD/DE = AB/AE (by similarity of triangles ABD and ADE)

BD/22 = 10/(x-22) (substituting BD = CE and AE = AC - CE - DE, and simplifying)

CE = (220 - 10x)/(x-22)

Since CE is equal in both expressions, we can equate them and solve for x

(5/8)(x-6) = (220 - 10x)/(x-22)

5x² - 196x + 1320 = 0

x² - 39.2x + 264 = 0

Using the quadratic formula, we get

x = 30.96 or x = 8.54

The length of AC must be positive, so we choose x = 30.96.
