the width of an architects desk is represented by four times x squared and the length is represented by the expression 2x cubed. what represents the area of the tabletop

Answers

You will use the formula A=lw to find the area. Substitute 2x^3 in for the length and 4x^2 for the width. You would multiply both of these. 2×4 = 8, and x cubed times x squared equals X to the fifth power. You will add the exponents together because the exponent tells you how many times to multiply that value. If there are three x multiplied together (in x cubes) and two x multiplied together(in x squared) that makes five x multiplied together. The answer is represented as A=8x^5. ^ means to the power of.

The cost, c(x), for a taxi ride is given by c(x) = 3x + 2.00, where x is the number of minutes. On a piece of paper, graph c(x) = 3x + 2.00. Then determine which answer matches the graph you drew, including the correct axis labels.

Answers

Since this is time and cost, we have no need for negatives, so we begin our graph at the origin (0, 0).  At 0 minutes, the cost would be $2.00, so 2 is our y-intercept.  For each successive minute, the cost goes up $3, so we go from (0, 2) to (1, 5), then to (2, 8), etc.

The y-intercept of 2.00 indicates that even if the ride was 0 minutes, there is still a flat fee of $2.00.

What is a slope?

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

The characteristics of the graph of the equation c(x) = 3x + 2.00.

The graph of c(x) = 3x + 2.00 is a straight line with a slope of 3 and a y-intercept of 2.00.

The x-axis represents the number of minutes, and the y-axis represents the cost in dollars.

The slope of 3 indicates that for every additional minute of the taxi ride, the cost increases by $3.

The y-intercept of 2.00 indicates that even if the ride was 0 minutes, there is still a flat fee of $2.00.

An investment of $750 will be worth $1500 after 12 years of continuous compounding at a fixed interest rate. What percent is the interest rate?

Answers

Final answer:

The interest rate is 100%, or 1 as a decimal, for continuously compounded interest.

Explanation:

To find the interest rate, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount ($1500)P is the principal amount ($750)r is the interest rate (unknown)n is the number of times interest is compounded per year (continuously compounded)t is the time in years (12)

Using the given information, we can plug in the values and solve for r:

$1500 = $750(1 + r/1)^(1*12)$2 = 1 + rr = $2 - 1 = $1

The interest rate is 100%, or 1 as a decimal, for continuously compounded interest.

The interest rate, for continuous compounding, is approximately 5.775%.

To find the interest rate for continuous compounding, we can use the formula for compound interest:

[tex]\[ A = P \times e^{rt} \][/tex]

Where:

- [tex]\( A \)[/tex] is the final amount of money,

- [tex]\( P \)[/tex] is the principal amount (initial investment),

- [tex]\( r \)[/tex] is the interest rate (annual rate in decimal),

- [tex]\( t \)[/tex] is the time the money is invested for (in years),

- [tex]\( e \)[/tex] is the base of the natural logarithm, approximately equal to 2.71828.

Given:

- [tex]\( P = $750 \)[/tex],

- [tex]\( A = $1500 \)[/tex],

- [tex]\( t = 12 \)[/tex] years.

We need to solve for [tex]\( r \)[/tex], the interest rate.

Step 1 :

**Substitute the Given Values into the Formulaa :

[tex]\[ 1500 = 750 \times e^{12r} \][/tex]

Step 2 :

**Divide Both Sides by 750**:

[tex]\[ \frac{1500}{750} = e^{12r} \][/tex]

[tex]\[ 2 = e^{12r} \][/tex]

Step 3 :

**Take the Natural Logarithm of Both Sides**:

[tex]\[ \ln(2) = \ln(e^{12r}) \][/tex]

[tex]\[ \ln(2) = 12r \ln(e) \][/tex]

[tex]\[ \ln(2) = 12r \][/tex]

Step 4 :

**Solve for [tex]\( r \)[/tex]**:

[tex]\[ r = \frac{\ln(2)}{12} \][/tex]

[tex]\[ r = \frac{0.693}{12} \][/tex]

[tex]\[ r = 0.05775 \][/tex]

Step 5 :

**Convert the Interest Rate to a Percentage**:

[tex]\[ r_{\text{percentage}} = 0.05775 \times 100\% \][/tex]

[tex]\[ r_{\text{percentage}} = 5.775\% \][/tex]

So, the interest rate is approximately 5.775%.

A field project superintendent earns an annual salary of $72,800, and she contributes $7900 per year to her 401(k) plan. If she has a required deduction for income taxes (federal, state, and local combined) of 28% of pretax income, how much does she have withheld in income taxes per year?

Answers

Contributions to one's 401K plan are taken out without paying tax on them (they are pre-tax contributions). In the end, when you retire you will pay taxes on the money but it is deferred for now.

What this means in terms of the question is that we should deduct the $7,900 first and then take 28% of what is left for taxes.

This person's salary is $72,800 a year and they set aside $7,900 for their retirement account (401K) so that leaves $72800-$7900 = $64,900

She now pays taxes of 28% on this amount ($64,900). Percent means "out of 100" so 28% means [tex] \frac{28}{100}=.28 [/tex] and to find 28% of 64900 we multiply (64900)(.28) = $18172.

That is she has $18,172 withheld in taxes each year.

Problem 1. Write the sum using summation notation, assuming the suggested pattern continues.
1 - 3 + 9 - 27 + ...

Answer: option C) summation of one times negative three to the power of n from n equals zero to infinity

Explanation:

1) Sequence: 1 - 3 + 9 - 27: given

2) ratio of two consecutive terms:

- 3 / 1 = - 3

9 / (-3) = - 3

-27 / (9) = - 3

=> ratio = - 3 means that every term is the previous one multiplied by - 3

3) terms

First term: 1 * (-3)^0 = 1

Second term: 1* (-3)^1 = - 3

Third term: 1 * (-3)^2 = 9

Fourth term: 1 * (-3)^3 = - 27

So, the summation is:

∞
∑ 1 * (-3)^n ,
n=0

which is read summation of one times negative three to the power of n from n equals zero to infinity => option C.



Problem 2. Write the sum using summation notation, assuming the suggested pattern continues.

- 4 + 5 + 14 + 23 + ... + 131

Answer: option  A) summation of the quantity negative four plus nine n from n equals zero to fifteen

Probe the statement A):

15
∑ (- 4 + 9n)
n=0

Now develop that summation: - 4 +9(0) - 4+ 9(1) - 4 + 9(2) - 4 + 9(3) +....+ - 4 + 9(15) = - 4 + 5 + 14 + 23 + 131

Which is the very same sequence given.Therefore, the first statement if right.


Problem 3. Write the sum using summation notation, assuming the suggested pattern continues.
25 + 36 + 49 + 64 + ... + n^2 + ...

Answer: option A) summation of n squared from n equals five to infinity

Explanation

First term: 25 = 5^2
Second term: 36 = 6^2
Third term: 49 = 7^2
Fourth term: 64 = 8^2

nth term n^2

last term: the sequence is infinite

So, you can see that the sequence is the sum of the square of the integers from n = 5 to infinity =
∞
∑  (n^2)
n = 5

which is what summation of n squared from n equals five to infinity means.


Problem 4. Find the sum of the arithmetic sequence.
-1, 2, 5, 8, 11, 14, 17

Answer: option A) 56

Explanation:

You just have to sum all the terms (since they are few numbers that is the best way): - 1 + 2 + 5 + 8 + 11 + 14 + 17 = 56

Answer: 56


Problem 5. Find the sum of the geometric sequence.
1, one divided by four, one divided by sixteen, one divided by sixty four, one divided by two hundred and fifty six

Answer: option D) 341 / 256

Explanation:
Write in form of fractions: 1 + 1/4 + 1/16 + 1/64 + 1/256

You'd better use the formula for the summation of a geometric sequence

k
∑  A * (r^n) = A * (1 - r^k) / (1 - r)
n=1

In this case: r = 1/4 (the ratio)
k = 5 (the number of terms)
A = 1 (the first term)

=> The sum = 1 * [1 - (1/4)^5 ] / [ 1 - 1/4], which when you simplify turns into 341 / 256 which is the option D.

Problem 6. Find the sum of the first 8 terms of the sequence. Show all work for full credit.
1, -3, -7, -11, ...

Answer: - 104

Explanation:

You can either sum the 8 terms or use the formula for the sum of an aritmetic sequence.

I will sum the 8 terms.

Note the the constant distance to sum is - 4, so the sum of the first eight terms is:

1  - 3 - 7 - 11 - 15 - 19 - 23 - 27 = - 104

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

The inequality for the sentence "Fifteen less than a number is at most 6" can be written as:

x - 15 ≤ 6

where x represents the unknown number.

To solve for x, we will add 15 to both sides of the inequality:

Does the equation x2 - 4x + y2 = -3 intersect the x-axis?

Answers

To find out whether or not the equation x^2 - 4x + y^2 = -3 intersects the x-axis, we must set y = 0 in the equation (because at every point on the x-axis, y = 0). 

x^2 - 4x + 0 = -3

We then want to solve for x. We can do this by factoring.

x^2 - 4x + 3 = 0

By factoring...

(x - 3)(x - 1)

We can set each of these equations = 0 to solve where the function crosses the x-axis.

x - 3 = 0
x = 3

x - 1 = 0
x = 1

So we know at x = 1 and x = 3, the function x^2 - 4x + y^2 = -3 intersects the x-axis.

Answer:

Yes, because the center is on the x-axis.

Step-by-step explanation:

First, write the equation in standard form by completing the square.

x2 - 4x + y2 = -3

x2 - 4x + 4 + y2 = -3 + 4

(x - 2)2 + y2 = 1

The circle is centered at (2, 0) with a radius of 1. Since the circle is centered on the x-axis, it intersects the x-axis two times, at (3, 0) and (1, 0).

X = Sqrt(13600)
X = 116.619

Diagonal = 116.62 yards
60^2 + 100^2 = c^2
3600 + 10000 = c^2
13600 = c^2
c = 116.62 yd

Which graph represents y – 1 = 2(x – 2)?

Answers

Answer:

The graph is attached below

Step-by-step explanation:

y – 1 = 2(x – 2)

y-1 = 2x - 4

add 1 on both sides

y = 2x - 3

To graph the given equation we make a table

Plug in some number for x and find out the value of y

x      y = 2x-3

-1       2(-1)-3= -5

0        2(0) -3= -3

1          2(1) -2= -1

The point to get the graph of the given equation is

(-1,-5)   (0,-3) (1,-1)

The graph is attached below

Answer:

The answer is the first graph or graph A.

BTW this is just the short answer...

Steve ordered plastic cases for storing his baseball cards. Each case has a length of 12 centimeters, a width of 6.5 centimeters ,and a height of 1.25 centimeters, what is the volume, in cubic centimeters, of one baseball card case?

Answers

For this case you should see the box as a rectangular prism.
 The volume of a rectangular prism is given by:
 V = (L) * (W) * (H)
 Where,
 L: length
 W: width
 H: height.
 Substituting the values we have:
 V = (12) * (6.5) * (1.25)
 V = 97.5 cm ^ 3
 Answer:
