assuming 7/10 eom means 7 - 10 days after, your answer would be A. April 18th, 2012.

Answer:

Option A. April 18,2012.

Step-by-step explanation:

This invoice of stationary  is dated 8 April 2012, and terms written on it 7/10 EOM.

It means 7% discount of the payment within 10 days or full payment at the End of the Month (EOM)

Therefore, the last day Sharon can take advantage is 10 days after the date of invoice.

Date of invoice = April 8, 2012

after 10 days = April 18, 2012

Option A. is the correct answer.

Answer:

[tex]f^{-1}(x)=-\frac{1}{5} x-\frac{4}{5}[/tex]

Step-by-step explanation:

It is called an inverse or reciprocal function of [tex]f[/tex] to another function [tex]f^{-1}[/tex] that fulfills that:

If [tex]f(a)=b[/tex], then [tex]f^{-1} (b)=a[/tex]

The inverse of [tex]f(x)=-5x-4[/tex] is:

We change the x for the y

[tex]x=-5y-4[/tex]

Now, let's clear y

[tex]y=\frac{x+4}{-5}[/tex]

Ordering

[tex]y = -\frac{1}{5} x-\frac{4}{5}[/tex]

So, the inverse of the function [tex]f(x)=-5x-4[/tex] is:

[tex]f^{-1}(x)=-\frac{1}{5} x-\frac{4}{5}[/tex]

Answer:

The direction of the given vector is 45° N of W

Step-by-step explanation:

* Lets revise the four directions with the four quadrants

- The four directions are:

# North which represented by the positive part of y-axis

# South which represented by the negative part of y-axis

# East which represented by the positive part of x-axis

# West which represented by the negative part of y-axis

∴ The first quadrant is between the East and the North

∴ The second quadrant is between the West and the North

∴ The third quadrant is between the West and the South

∴ The fourth quadrant is between the East and the South

* The direction of any vector is tan Ф, where Ф is the angle between

 the vector and the x-axis, then:

- The direction of North of East is 45° ⇒ first quadrant

- The direction of North of West is 45° ⇒ second quadrant

- The direction of South of West is 45° ⇒ third quadrant

- The direction of South of East is 45° ⇒ fourth quadrant

* Now lets solve the problem

∵ The direction of the vector is between the North and the West

  (its vertex in the second quadrant)

∴ Its direction is 45° North of West

* The direction of the given vector is 45° N of W

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where h and k are the coordinates of the center of the circle and the radius is squared.  The radius is easy...take the square root of 25 to get that the radius is 5.  Since the pattern for the standard form is "x-" and "y-", if (x+2)^2 is the horizontal placement of the center, it actually was originally written as (x-(-2))^2, so the h coordinate is -2.  Same goes for the vertical movement of the center.  (y-(5))^2 means that the k coordinate is a positive 5.

Answer:

an = 10 (-8)^(n-1)

Step-by-step explanation:

In a geometric series, each term is multiplied by a common ratio to get the next term.  Such that:

an = a₁ (r)^(n-1)

Here, the first term, a₁, is 10.  The common ratio, r, is -8, because each term is multiplied by -8 to get the next term.  So:

an = 10 (-8)^(n-1)

Your answer is correct, well done!

The recursive rule of the geometric sequence is [tex]a_{n+1}= -8a_n[/tex] where a1 = 10

The geometric sequence is given as:

10, −80,  640, −5120, ...

Start by calculating the common ratio (r)

[tex]r = \frac{a_{n-1}}{a_n}[/tex]

Substitute 2 for n

[tex]r = \frac{a_{2}}{a_1}[/tex]

Substitute known values

[tex]r = \frac{-80}{10}[/tex]

Evaluate the quotient

[tex]r = -8[/tex]

Substitute -8 for r in [tex]r = \frac{a_{n+1}}{a_n}[/tex]

[tex]-8 = \frac{a_{n+1}}{a_n}[/tex]

Cross multiply

[tex]a_{n+1}= -8a_n[/tex]

Hence, the recursive rule of the geometric sequence is [tex]a_{n+1}= -8a_n[/tex] where a1 = 10

The directions tell you what you need to know. It is a matter of adding up the values shown and finding the missing number to make the total be -20. Of course, it works best to start with a row, column, or diagonal that has 4 numbers already.Then, you're only finding the 5th number.

You can start with either diagonal, column 1 or 4, and row 4 or 5. Filling the missing numbers in those spots (red) will let you find the remaining missing numbers (green, then blue).

The square at row 2, column 2 can be filled on the first round using the down-right diagonal. I have shown it as filled on the second round after row 5 column 2 is filled.

Using a spreadsheet can make this easier, because you can write formulas for the sums in each row, column, and diagonal. Then you're just making those sums be -20.

Following PEMDAS, we should do 320/80 first which is 4

Then the equation becomes 4+3=7

The remaining 4600 numbers are neither multiples of 2 nor 5.

There are 10,000 total four-digit numbers (1000 through 9999).

Multiples of 2 end in 0, 2, 4, 6, and 8.

4-digit numbers are those numbers that consist of only 4 digits in which the first digit should be 1 or greater than 1 and the rest of the digits can be any number between 0 and 9.

There are 9*10*10*5 = 4500 four-digit multiples of 2.

Multiples of 5 end in 0 or 5.

There are 9*10*10*2 = 1800 four-digit multiples of 5.

There is redundancy between the two sets of numbers, namely those that end in 0, which are both multiples of 2 and 5.

There are 9*10*10*1 = 900 four-digit multiples of both 2 and 5.

Then there are 4500 + 1800 - 900 = 5400

total four-digit numbers that are either multiple of 2 or 5,

Answer:

Third choice is the one you want

Step-by-step explanation:

First off, we need to remember that for a line to be perpendicular to another line, its slope is the opposite reciprocal to the other line. The slope of our line is -1/4, so the opposite reciprocal slope is +4/1 or just 4. Now we know that m = 4.

The point-slope form of a line is

[tex]y-y_{1}=m(x-x_{1})[/tex]

where m is the slope, y1 is the y coordinate of the point, and x1 is the x coordinate of the point. Filling in:

[tex]y-5=4(x-(-3))[/tex] which simplifies to

[tex]y-5=4(x+3)[/tex] which simplifies further to

[tex]y-5=4x+12[/tex]

Add 5 to both sides to get the equation into slope-intercept form:

y = 4x + 17

choice 3

Answer:

30

Step-by-step explanation:

We need to find the greatest common factor of 120 and 144.

First, write the prime factorization of both:

120 = 2³×3×5

144 = 2⁴×3²

Both have 2³ and 3 in common, so the GCF is:

GCF = 2³×3

GCF = 24

So the side length is 24 cm.  The number of squares along the width is:

120 / 24 = 5

And the number of squares along the length:

144 / 24 = 6

So the number of squares need to fill the entire area is 5×6 = 30.  This is the least number of squares with whole-number side lengths that he can use.

Answer:

• arc PS = 40°

• arc UV = 24°

Step-by-step explanation:

There are relationships between the arcs intercepted by secant lines and the angle the secant lines make with each other. In these problems, you are expected to make use of these relationships, along with others you have learned about triangles.

The relationships are basically these:

• when the secants intersect inside the circle, the angle between them is half the sum of the intercepted arcs.

• when the secants intersect outside the circle, the angle between them is half the difference of the intercepted arcs.

__

First problem:

The angle between the secants QS and PR is shown to be 50°. Intercepted arc QR is shown to be 60°. You are asked to find the other intercepted arc, PS. Based on the above, we know ...

∠POS = (1/2)(arc PS + arc QR)

50° = (1/2)(arc PS + 60°)

Multiplying by 2, we get ...

100° = arc PS + 60°

Subtracting 60°, gives ...

40° = arc PS

__

Second problem:

We need to name a couple of points so we can describe more clearly what is going on. Call the point on arc PS where line QT intersects it point R. Call the point where line QT crosses line SU point X. (Point X is the vertex of the 99° angle.)

The relations described above tell us ...

angle W = (1/2)(arc PS - arc UV)

In this equation, we only know the value of arc PS = arc PR + arc RS = 20° + 94° = 114°.

But, we know two of the angles in triangle QWX. They are angle Q = 36° and angle X = 99°. Then angle W must be ...

angle W = 180° -36° -99° = 45°

Now, we can finish the above equation involving arc UV:

45° = (1/2)(arc PS - arc UV) . . . . . put the values we know in the secant relation

90° = 114° -arc UV

arc UV = 114° -90° = 24° . . . . . . . .solve for arc UV

Coefficient of middle term that contains x, in [tex]x^2-7x+c[/tex] -7.

Take half of that so we get [tex]-\frac{7}{2}[/tex].

Then take square of the half value.

We get [tex]\left(-\frac{7}{2}\right)^2=\frac{49}{4}[/tex].

We add the square value to make perfect square trinomial.

Hence final answer is [tex]\frac{49}{4}[/tex].

Answer:

D. [tex]\frac{49}{4}[/tex].

Step-by-step explanation:

We have been given a trinomial [tex]x^2-7x+c[/tex]. We are asked to find the value of c, which will make the expression a perfect square trinomial.

We know that a perfect trinomial is in form [tex]a^2\pm2ab+b^2[/tex].

We will use complete the square process to solve for c.

To complete a square, we need to add square of half the coefficient of x term. We can see that coefficient of x is -7, so the value of c would be:

[tex](\frac{b}{2})^2=(\frac{-7}{2})^2=\frac{(-7)^2}{2^2}=\frac{49}{4}[/tex].

Therefore, the value of c required to make the given expression a perfect trinomial is [tex]\frac{49}{4}[/tex] and option D is the correct choice.

Answer:

A. 3:7

Step-by-step explanation:

The volume of the smaller cube is 216 m³.

The volume of the larger cube is 2744 m³

Let the  similarity ratio be [tex]l:L[/tex]

The volume of these two cubes are in the ratio:

[tex]l^3:L^3=216:2744[/tex]

This implies that:

[tex](\frac{l}{L})^3 =\frac{216}{2744}[/tex]

We take the cube root of both sides to obtain:

[tex]\frac{l}{L} =\sqrt[3]{\frac{216}{2744}}[/tex]

[tex]\frac{l}{L} =\frac{6}{14}[/tex]

This simplifies to:

[tex]\frac{l}{L} =\frac{3}{7}[/tex]

The ordered triple for vector u is then [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex]

Explanation:

To find the ordered triple that represents the vector u in the equation [tex]\( u = 3v - \frac{2}{3}w + 2z \)[/tex], we need to perform the vector operations on v = (4, -3, 5), w = (2, 6, -1) , and z = (3, 0, 4).
Step 1: Multiply vector v by 3.
[tex]\[ 3v = 3 * (4, -3, 5) = (3*4, 3*(-3), 3*5) = (12, -9, 15) \][/tex]
Step 2: Multiply vector w by [tex]\( -\frac{2}{3} \)[/tex].
[tex]\[ -\frac{2}{3}w = -\frac{2}{3} * (2, 6, -1) = (-\frac{2}{3}*2, -\frac{2}{3}*6, -\frac{2}{3}*(-1)) = (-\frac{4}{3}, -\frac{12}{3}, \frac{2}{3}) \\\\\[ -\frac{2}{3}w = (-\frac{4}{3}, -4, \frac{2}{3}) \\\\\[ -\frac{2}{3}w = (-1\frac{1}{3}, -4, \frac{2}{3}) \][/tex]
Step 3: Multiply vector \( z \) by 2.
[tex]\[ 2z = 2 * (3, 0, 4) = (2*3, 2*0, 2*4) = (6, 0, 8) \][/tex]
Step 4: Add the resulting vectors from steps 1, 2, and 3.
We add the corresponding components from each vector:
[tex]\[ (12, -9, 15) + (-1\frac{1}{3}, -4, \frac{2}{3}) + (6, 0, 8) \][/tex]
To add these, perform the addition component-wise:
- For the first component:
[tex]\[ 12 + (-1\frac{1}{3}) + 6 = 12 - 1\frac{1}{3} + 6 = 11\frac{2}{3} + 6 = 17\frac{2}{3} \][/tex]
- For the second component:
[tex]\[ -9 + (-4) + 0 = -9 - 4 = -13 \][/tex]
- For the third component:
[tex]\[ 15 + \frac{2}{3} + 8 = 15 + \frac{2}{3} + 8 = 23\frac{2}{3} \][/tex]
The ordered triple for vector u is then [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex].
However, to express this as a proper ordered triple, we usually write the components as fractions or decimals. So, let's convert the fractions into decimals:
[tex]\[ 17\frac{2}{3} = 17 + \frac{2}{3} = 17 + 0.666\ldots \approx 17.67 \\\\\[ 23\frac{2}{3} = 23 + \frac{2}{3} = 23 + 0.666\ldots \approx 23.67 \][/tex]
So the ordered triple for vector u in decimal form is approximately u = (17.67, -13, 23.67).

Please note that the approximation is to two decimal places. If exact values are desired, it is best to leave the answer in fraction form as [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex].

Final answer:

The expression 3 · (5 + 4)2 – 42 evaluates to 227, after applying the order of operations to add, square, multiply, and subtract the given numbers.

Explanation:

To evaluate the given exponential expression 3 · (5 + 4)2 – 42, we follow the order of operations, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we add the numbers inside the parentheses: (5 + 4), which equals 9.

Next, we raise this sum to the power of 2: 92, which is equal to 81.

Then, we calculate 42, which is 16.

Now, we multiply 3 by the result of 92: 3 · 81, giving us 243.

Lastly, we subtract 42 from this result: 243 – 16, yielding the final answer of 227.

The final result of the expression 3 · (5 + 4)2 – 42 is 227.
