Answer:

Step-by-step explanation:

1. The problem preamble gives you the two ways to name the vector. You can use either its name, or the two end points. (The starting point is named first, as it is with a ray.)

The vector shown can be referred to by the names ...

  u  or  AB

__

2. The right triangle has legs 4 and 5, so the length is ...

  length = √(4² +5²) = √41

  length ≈ 6.4

__

3. Typically, you're given the leg lengths. The ratio of these is the tangent of the angle. The angle can be found using the inverse tangent function.

__

4. The tangent of the angle is the slope of the vector:

  tan(A) = 5/4

  A = arctan(5/4) ≈ 51°

__

5. The first letter named is the starting point of the vector. Vector MN starts at point M and ends at point N. Vector NM starts at N and ends at M. The directions of the two vectors are opposites.

__

6. A ray is like a vector of infinite length. The name of a ray includes a point on the ray. The name of a vector includes both end points. It is of finite length.

Additional comment

A lot of math is invented to describe how things work in the real world. A vector is often used to represent velocity or force and other things that can be described by a magnitude and direction in the real world. A ray is more often used in problems in geometry, where that abstract concept serves a useful purpose.

Answer:

y=3x-11

Step-by-step explanation:

slope-1-(-5)/4-2=6/2=3

y=mx+b

y=3x+b

so plugging the values in

1=12+b

b=-11

y=3x-11

Answer:

(3,8)

Step-by-step explanation:

First, you need to graph a triangle using the points given.

Then reflect across y = x

R is (3,0) which when reflected across y = x is (0,3)

S is (3,3) which when reflected across y = x is (3,3)

R is (4,0) which when reflected across y = x is (0,4)

Answer:[tex]\dfrac{6}{17}[/tex]

Step-by-step explanation:

Reciprocal of  [tex]3-x\ \text{is}\ \dfrac{1}{3-x}[/tex]

Reciprocal of [tex]1-2x\ \text{is}\ \dfrac{1}{1-2x}[/tex]

According to question

[tex]\Rightarrow \dfrac{1}{3-x}+\dfrac{1}{1-2x}=6\times \dfrac{1}{3-4x}\\\\\Rightarrow \dfrac{(1-2x)+(3-x)}{(1-2x)(3-x)}=\dfrac{6}{3-4x}\\\\\Rightarrow \dfrac{4-3x}{(1-2x)(3-x)}=\dfrac{6}{3-4x}[/tex]

[tex]\Rightarrow (4-3x)(3-4x)=6(1-2x)(3-x)\\\Rightarrow 12-16x-9x+12x^2=18-6x-36x+12x^2\\\Rightarrow 12x^2-25x+12=18-42x+12x^2=0\\\Rightarrow 42x-25x=6\\\Rightarrow 17x=6\\\Rightarrow x=\dfrac{6}{17}[/tex]

Answer:

  g(x) = (5x +26)/(x+5)

Step-by-step explanation:

To translate the function right h units and up k units, the transformation is ...

  f(x -h) +k

You want h=-4 (4 units left) and k=-1 (1 unit down). So, the translated function is ...

  [tex]f(x+4)-1=\dfrac{6(x+4)+7}{(x+4)+1}-1\\\\=\dfrac{6x+31}{x+5}-1=\dfrac{6x+31-(x+5)}{x+5}\\\\=\dfrac{5x+26}{x+5}[/tex]

The translated function is ...

  g(x) = (5x +26)/(x+5)

__

The original function is in red with asymptotes shown in orange. The translated function is in purple with the asymptotes shown in blue. You can see that the function has been moved 4 left and 1 down.

Answer:

18 inches or 1 foot 6 inches/1 foot and a half

Step-by-step explanation:

one foot is 12 inches long so you take the number of feet given (7—we'll worry about the half later) and multiply by the number of inches that are in a foot (12)

7×12=84

then half a foot is 6 inches so 84+6=90 inches

then we take 90 and divide it by 5 (to get the length of one piece)

90/5=18 inches

you can keep it as 18 inches or convert it into feet which you subtract 12 from 18, and you have 6 inches left which is 1 foot and a half

Answer:

Andrew is wrong

Step-by-step explanation:

You need to add the fractions together. To add fractions you need a common denominator, so for mike 2/4 changes to 6/12 and 1/3 changes to 4/12 meaning he read 10/12 of the book. Andy read 1/2 or 5/10 and 1/5 or 2/10 so 7/10. By cross multiplying we see that 10/12 is greater so mike read more.

Answer:

Mike read more of the book

Step-by-step explanation:

I made 1/3 and 1/5 into a equal fraction and 1/3 would be 5/15 and 1/5 would be 3/15 and 2/4 and 1/2 are the same so it just comes to to 1/3 and 1/5. Mike read more of the book than Andy

Answer:

6x³ + x² - 9x +10

Step-by-step explanation:

This one uses typical FOIL multiplication.

We are given the expression (3x + 5) (2[tex]x^{2}[/tex] – 3x + 2)

Using FOIL, we multiply every term in all ways. We can rewrite the expression as (3x · 2[tex]x^{2}[/tex]) + (3x · -3x) + (3x · 2) + (5 · 2[tex]x^{2}[/tex]) + (5 · -3x) + (5 · 2)

Which simplifies to 6x³ - 9x² + 6x + 10x²- 15x + 10

Which we can further simplify to 6x³ + x² - 9x +10

Answer:6x³ + x² - 9x +10

Answer:

The Answer is B.

Step-by-step explanation:

Answer:

B. 0.75x +1.5 = 10

Step-by-step explanation:

We know the first that no matter what we will have to pay $1.50 for the first mile. So if we were to try to figure how many miles you can drive in a taxi for $10 you'd multiply $0.75 by X. Therefore the answer is B. because 0.75 multiplied by x plus one will give you the answer.

Let x represent the number of hours that he spent washing cars.

Let y represent the number of hours that he spent landscaping.

In a week, he can work no more than 19 total hours. This means that

x + y ≤ 19- - - - - - - - - - - -1

Jacob is working two summer jobs, making $10 per hour washing cars and making $8 per hour landscaping. He must earn at least $170. This means that

10x + 8y ≥ 170 - - - - - - - - - -2

If Jacob worked 4 hours landscaping, it means that

x + 4 ≤ 19    x ≤ 19 - 4    x ≤ 15

Also,  10x + 8 × 4 ≥ 170     10x + 32 ≥ 170

10x ≥ 170 - 32          10x ≥ 138

10x ≥ 138/10             x ≥ 13.8

The minimum number of hours is 14

Answer:

36 days

Step-by-step explanation:

Total distance driven = 4 1/2 miles = 9/2 miles

Months of June and July ;

Miles driven per day = 1/8

Number of days Parker went driving :

Total miles driven / miles driven per day

9/2 miles ÷ 1/8 miles

9 /2 * 8 /1

(9 * 8) / (2 * 1)

72 / 2

= 36 days

Hence, Parker drove for 36 days

Answer:

3 comparisons

Step-by-step explanation:

Given:

[tex]List: 1 , 5 ,10 , 13 , 48 , 68 , 100 , 101[/tex]

Required

Determine the number of comparisons to get to 101

The length of the list is 8. So, the first index is 0 and the last is 7.

We have:

[tex]List[0] = 1[/tex]   [tex]List[1] = 5[/tex]   [tex]List[2] = 10[/tex]     [tex]List[3] = 13[/tex]    

[tex]List[4] = 48[/tex]    [tex]List[5] = 68[/tex]    [tex]List[6] = 100[/tex]    [tex]List[7] = 101[/tex]

Initially:

[tex]begin = 0[/tex] -- first index

[tex]end = 7[/tex] --- last index

Start by calculating the mid-item

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(0 + 7)[/tex]

[tex]mid = \frac{1}{2}(7)[/tex]

[tex]mid = 3.5[/tex]

[tex]mid = 4[/tex] --- approximated.

The mid-index is 4 and the item is:

[tex]List[4] = 48[/tex]

101 is on the right of 48.

So, we calculate the new begin index.

[tex]begin = mid + 1[/tex]

[tex]begin= 4 +1[/tex]

[tex]begin = 5[/tex]

Calculate mid

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(5 + 7)[/tex]

[tex]mid = \frac{1}{2}(12)[/tex]

[tex]mid= 6[/tex]

The mid-index is 6 and the item is:

[tex]List[6] = 100[/tex]

101 is on the right of 100.

So, we calculate the new begin index.

[tex]begin = mid + 1[/tex]

[tex]begin = 6 +1[/tex]

[tex]begin= 7[/tex]

Calculate mid

[tex]mid = \frac{1}{2}(begin + end)[/tex]

[tex]mid = \frac{1}{2}(7+7)[/tex]

[tex]mid = \frac{1}{2}(14)[/tex]

[tex]mid = 7[/tex]

At this point, the mid-index is at 101

i.e.

[tex]List[7] = 101[/tex]

This implies that, we have located 101.

So far, we made 3 comparisons

[tex]4[/tex] comparisons are needed to find the number [tex]101[/tex] in the list.

Binary search algorithm searches for a number in a sorted list/array. It does this by first comparing the number in the middle of the array with the number searched for, then recursively continuing the search on either the left-half or right-half of the array if the middle comparison failed.

The element [tex]101[/tex], is at the rightmost end of the array. This means that the algorithm will have a worst case running time. The worst case running time of a binary search algorithm is given by

[tex]T_n=\lfloor log_2(n)+1\rfloor[/tex]

where [tex]\lfloor x \rfloor[/tex] is the floor function that gives the greatest integer less than or equal to [tex]x[/tex], and [tex]log_2(n)[/tex] is the logarithm of [tex]n[/tex] to base [tex]2[/tex]

In our case, the number of elements in the array, [tex]n=8[/tex]. So,

[tex]T_n=\lfloor log_2(n)+1\rfloor\\\implies T_8=\lfloor log_2(8)+1\rfloor = 4\\[/tex]

So, the algorithm will need to make [tex]4[/tex] mid-array comparisons to get to [tex]101[/tex].
