A puzzle contains a triangular piece with a base of 3 in. and a height of 4 in. A manufacturer wants to make 80 puzzles. Find the amount of wood used if each puzzle contains 20 triangular pieces.

Answers

Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used

Answer:

9600 square inches.

Step-by-step explanation:

We have been given that a puzzle contains a triangular piece with a base of 3 in. and a height of 4 in.

The would used for each triangular piece would be equal to area of triangle.

[tex]\frac{1}{2}\times 3\text{ in}\times 4\text{ in}=3\text{ in}\times 2\text{ in}=6\text{ in}^2[/tex]

Each puzzle contains 20 triangular pieces, so wood used for each piece of puzzle would be 20 times 6 square inches.

[tex]\text{Wood used for each puzzle}=20\times 6\text{ in}^2[/tex]

[tex]\text{Wood used for each puzzle}=120\text{ in}^2[/tex]

[tex]\text{Wood used for 80 puzzles}=80\times 120\text{ in}^2[/tex]

[tex]\text{Wood used for 80 puzzles}=9600\text{ in}^2[/tex]

Therefore, 9600 square inches of wood is needed to make 80 puzzles.

Which of the following is an odd function? f(x) = x3 + 5x2 + x mc023-1.jpg f(x) = x2 + x f(x) = –x

Answers

Given the functions
(a) f(x) = x³ + 5x² + x
(b) f(x) = x² + x
(c) f(x) = -x

Function (a)
f(-x) = (-x)³ + 5(-x)² + (-x)
       = -x³ + 5x² - x
       = -(x³ - 5x² + x)
The function is neither even nor odd.

Function (b)
f(-x) = (-x)² + (-x)
        = -(-x² + x)
The function is neither even nor odd.

Function (c)
f(-x) = -(-x)
       = x
       = -f(x)
Because f(-x) = -f(x) the function is odd.

Answer: f(x) = -x is an odd function.

By evaluating each function in -x, we will see that the only odd one is:

f(x) = -x

What is an odd function?

We say that a function is odd if:

f(-x) = f(x)

Then we just need to check that for the given functions, let's see what we get:

1) f(-x) = (-x)^3 + 5*(-x)^2 + (-x) = -x^3 + 5x^2 - x ≠ -f(x)

2) f(-x) = (-x)^2 - x= x^2 - x ≠ -f(x)

3) f(-x) = -(-x) = x = -f(x)

So the only odd function is the third one, one useful thing that you may need to know is that usually when you see even exponents, that function will not be odd.

You have just won the lottery and will receive $1,000,000 in one year. you will receive payments for 30 years, and the payments will increase 3 percent per year. if the appropriate discount rate is 7 percent, what is the present value of your winnings?

Answers

Final answer:

The student's question involves determining the present value of annuity payments from a lottery winning, which increase over time and are discounted by a particular rate. The present value is calculated using a formula for a growing annuity, taking into account factors like the growth rate of the payments, the discount rate, and the number of periods. An example with a simple bond issue is provided to illustrate the process of calculating present value at different discount rates.

Explanation:

The student's question pertains to calculating the present value of annuity payments that increase at a fixed percentage rate over time, using a specified discount rate. This is a common exercise in finance and economics, especially related to determining the value of future cash flows given a particular rate of return (or discount rate). To solve the problem, we use the present value formula for a growing annuity.

For the lottery winnings scenario, we would calculate the present value of each individual payment and then sum them up. The first payment of $1,000,000 is received in one year, and it increases by 3 percent each year for 30 years. The discount rate is 7 percent. To analyze this, we must consider the effects of inflation and the time value of money, which is why the payments are 'discounted' back to their present value at the prevailing discount rate.

The general formula for the present value of a growing annuity is:

PV = P * [(1 - ((1 + g)/(1 + r))^n) / (r - g)]

where PV is the present value, P is the first payment, g is the growth rate of the payments, r is the discount rate, and n is the number of periods.

Using the simple two-year bond example provided, the present value calculations at an 8% discount rate are:

$240/(1+0.08) = $222.22

$3,240/(1+0.08)^2 = $2,777.78

Total present value = $222.22 + $2,777.78 = $3,000

If the discount rate increases to 11%, the new present values would be calculated using the higher rate, resulting in a lower total present value for the bond. The calculations reflect the principle that if the cost of borrowing money increases (higher discount rate), the present value of future payments decreases.

The given four consecutive even integers are 2, 4, 6, 8

What are even numbers and  how can we write consecutive even numbers?

Even numbers are numbers which are divisible by two.

Any even number can be written as 2n , where n is any integer

If we increase n by 1 then next even number will be obtained. Then the consecutive even numbers be 2n , 2 (n+1), 2(n +2) , 2 (n+3), ....... so on.

Given that the sum of four consecutive even integers is 20

Let the four consecutive even integers are :

2n , 2(n+1) , 2(n+2), 2( n+3)

Then

⇒2n + 2(n+1) + 2(n+2) + 2( n+3) = 20

⇒ 2n + 2n +2 +2n +4 + 2n +6  =20

⇒ 8n + 12 =20

⇒ 8n = 20-12

⇒ 8n = 8

n =8/8 = 1

Therefore, the given four consecutive even integers are 2, 4, 6, 8

Which statement describes the translation of . y= -1/2(x-2) ^2 from standard position? A) Moved up and to the right. B) Moved up and to the left. C) Moved down and to the left. D) Moved down and to the right. .

Answers

The answer D) Moved down and to the right is correct.

Answer:  The correct option is

(D) Moved down and to the right.

Step-by-step explanation:  We are given to select the statement that best describes the translation of the following function from the standard position.

[tex]y=-\dfrac{1}{2}(x-2)^2~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

This is an equation of a parabola.

The standard position of a parabola of this type is

[tex]y=x^2,[/tex]

where the vertex is at (0, 0). Since the coefficient of x² is positive, so the parabola opens upwards.

Now, from equation (i), we have

the vertex of the parabola is at (2, 0) and since the coefficient of x² is negative, so the parabola opens downwards.

Also, the vertex (0, 0) has been shifted to (2, 0), so the parabola is moved 2 units to the right.

Therefore, the given parabola is moved down and 2 units to the right as compared to the standard position.

The images of the given parabola (i) and the standard parabola are shown in the attached figure below.

Thus, (d) is the correct option.

A diver descends from an elevation of 6 feet below sea level to an elevation
of 98 feet below sea level in 4 equal intervals. What was the diver’s change in
elevation in each interval? Explain how you solved this problem.

Answers

So first, we want to find how much in total did his elevation change. So we want to subtract the him starting from 6 feet below sea from the 98 feet below sea level, to get 92 feet.

Now, since he descended in four equal intervals, we can just divide 92 into four equal parts, or divide by 4, to get 23 feet.

So the diver's change in elevation in each interval was (negative?) 92 feet.

the product of the binomial by the trinomial is [tex]y^3+27[/tex].

Step-by-step explanation:

Binomial is the term having two different term and trinomial  having three different terms.

Here, Binomial is [tex]y+3[/tex] and trinomial is [tex]y^2-3y+9[/tex]

We have find the product of the binomial by the trinomial.

[tex](y+3)(y^2-3y+9)[/tex]

Multiply each term of binomial with trinomial,

[tex]\Rightarrow y(y^2-3y+9)+3(y^2-3y+9)[/tex]

[tex]\Rightarrow y^3-3y^2+9y+3y^2-9y+27[/tex]

Combining like term, we get,

[tex]\Rightarrow y^3+(3-3)y^2+(9-9)y+27[/tex]

[tex]\Rightarrow y^3+27[/tex]

Thus, the product of the binomial by the trinomial is [tex]y^3+27[/tex].

Hence, option (1) is correct.

If a car travels 23 miles on 1.0 gal of gas, how many liters of gasoline are needed for a 135 mile trip?

Answers

Solution can be gained by using "Product of means = Product of extremes" concept. So the information we have is 23 miles on 1 gal and 135 mile on 'x' gal. 23 : 1 :: 135 : x As per Product of means = Product of extremes, 23 multiplied x = 135 multiplied by 1. And x will be 135 divided by 23 which is 5.86 gal Now, we have to convert gal to liters, 1 gal = 3.78 liters, so 5.86 gal = 5.86 multiplied by 3.78, which is 22.15 liters. Hence, 22.15 liters of gasoline are needed for a 135 mile trip

Three orders are placed at a pizza shop. two small pizzas, a liter of soda, and a salad cost $14; one small pizza, a liter of soda, and three salads cost $15; and three small pizzas, a liter of soda, and two salads cost $22. how much does each item cost?

Answers

To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:

let x cost of small pizzas
     y cost of soda
     z cost of salad
 
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14

one small pizza, a liter of soda, and three salads cost $15

x + y + 3z = 15

three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22

Solving for x, y and z, we will have:

x = $ 5
y = $ 1
z = $ 3
Final answer:

We can solve this problem by setting up a system of equations using the given information and using algebraic methods to solve for each variable, which represent the cost of the individual items.

Explanation:

This question can be solved by using the method of linear equations. Let's denote the cost of a small pizza as P, a liter of soda as S, and a salad as A. From the given information, we can create three equations:

2P + S + A = $14 P + S + 3A = $15 3P + S + 2A = $22

By solving these equations, we can determine the prices of the individual items. The details of solving these equations may vary based on your level of comfort with algebra and systems of equations, but the general method involves isolating one variable in one equation and then substituting it into the other equations to eventually solve for each variable.
