Assume that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year. Find when the sale of cars will be more then the sale of motorcycles.

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:

93.66 but you can’t use only .66 of a container so I would say round up so 94

Step-by-step explanation:

The number of containers that Casey used will be 94 containers.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

Casey has 281 tennis balls. She will put them in containers that hold 3 tennis balls.

Then the number of containers that Casey used will be given by the division of the numbers 281 and 3.

⇒ 281 / 3

⇒ (279 + 2) / 3

⇒ 279 / 3 + 2 / 3

⇒ 93 + 2/3

⇒ 93 + 0.667

⇒ 93.667 or 94

The number of containers that Casey used will be 94 containers.

u=(14/3  ,-13,23/3)

Step-by-step explanation:

Given

u=3v-2/3 w+2z

And

v=(4,-3,5)

w=(2,6,-1)

z=(3,0,4)

Putting the values of v,w and z

u=3(4,-3,5)-2/3 (2,6,-1)+2(3,0,4)

u=(12,-9,15)-(4/3,12/3,-2/3)+(6,0,8)

=(12,-9,15)-(4/3,4,-2/3)+(6,0,8)

We will perform the addition first..

=(12,-9,15)-(4/3+6 ,4+0,-2/3+8)

= (12,-9,15)-(22/3,4,22/3)

Subtraction will give us:

=(14/3  ,-13,23/3)

Final Answer:

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].

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

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.

7 is a prime number so that can't be factored more.

There is no common factor of 7 and 4 except 1.

there is no common factor of w and [tex]m^3[/tex].

Hence required greatest common factor of given algebraic expressions 7w and [tex]4m^3[/tex] is 1.

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

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

Answer:

It changes negative numbers to positive.

Step-by-step explanation:

Absolute value is the measure of a numbers distance from 0. You can't have negative distance, so absolute value of negative numbers is positive and absolute value of positive numbers is always positive. The absolute values of 5 and -5 are both 5 because they are both 5 units away from 0 on a number line, just in opposite directions.

Final answer:

The absolute value of a number measures its distance from zero, ignoring direction. For vectors, it describes the magnitude without considering direction, remaining positive even when multiplied by a negative scalar. The concept is vital in many areas of math and science, such as physics in calculating displacement and in sound when determining beat frequency.

Explanation:

The absolute value of a number or an expression essentially measures its distance from zero on a number line, without considering direction. For vectors, the concept is similar; the magnitude of the vector becomes the absolute value of cA, which indicates its size irrespective of its direction. If the scalar c is positive, the vector maintains its direction. In contrast, if c is negative, the direction is reversed. However, the magnitude, given by the absolute value, remains positive.

For instance, in physics, the concept of absolute value is important when dealing with displacements since displacement is a vector. If the total displacement is a negative value, like -2 m, its magnitude is the absolute value, which is 2 m; thereby indicating that the actual 'size' or length of displacement is 2 m. Likewise, in the context of statistics, the absolute value of a z-score (deviation from the mean) indicates how far a score is from the mean, regardless of whether it's above or below it.

In the field of sound, the concept of absolute value becomes important when calculating beat frequencies, because frequencies cannot be negative. Hence, the beat frequency is the absolute value of the difference between two frequencies, ensuring that the result is always a positive number, indicative of a real-world, physical attribute.
