Answer:

K5.60.

Step-by-step explanation:

The vector v can be decomposed into v₁ = -2i - 2j and v₂ = -6i + 6j.

The decomposition of the vectors is calculated as follows;

v₁ = (v · w / |w|²) w

v₂ = v - v₁

The dot product of v and w is calculated as;

v · w = (-8)(1) + (4)(1)

v · w = -4

The magnitude of w is calculated as;

|w| = √1² + 1²)

|w|= √2

|w|² = 2

The value of v₁ is calculated as;

v₁ = (-4 / 2) (i + j)

v₁  = -2i - 2j

The value of v₂ is calculated as follows;

v₂ = v - v₁

v₂  = (-8i + 4j) - (-2i - 2j)

Sure, I'd be happy to help you with this problem!

Given that the ratio of boys to girls in the school is 4:3, we can say that for every 4 boys, there are 3 girls.

Let's start by finding the total number of students in the school, using the information that there are 18 girls.

If 3 girls represent a part of the whole, then we can find the total number of parts by dividing the total number of girls by 3:

18 girls ÷ 3 = 6 parts

So, there are 6 parts in the whole.

Now, since there are 4 boys for every 3 girls, we know that for every 7 parts (4 boys + 3 girls), there are 4 boys.

To find the total number of boys, we need to figure out how many groups of 7 parts there are in the whole.

6 parts ÷ 7 = 0 with a remainder of 6

This tells us that there are 0 groups of 7 parts in the whole, with 6 parts left over.

Since we know that for every 7 parts there are 4 boys, we can find the number of boys in the remaining 6 parts by multiplying 4 by the fraction of 6/7:

4 boys × 6/7 = 24/7 boys

This tells us that there are 24/7 boys in the remaining 6 parts.

To find the total number of boys in the school, we need to add the number of boys in the groups of 7 parts and the number of boys in the remaining 6 parts:

0 groups of 7 parts × 4 boys per group = 0 boys

6 parts × 4 boys per 7 parts = 24/7 boys

Total number of boys = 0 boys + 24/7 boys = 24/7 boys

So, there are 24/7 boys in the school. We can simplify this fraction by dividing both the numerator and the denominator by 3:

24/7 ÷ 3/3 = 8/7 boys

Therefore, there are 8/7 boys in the school, which is approximately 1.14 boys.

However, since we cannot have a fraction of a person, we can round this number to the nearest whole number, which is 1.

Therefore, there is 1 boy in the school for every 3 girls, making a total of:

1 boy × 18 girls = 18 boys

So, there are 18 boys in the school.

Given that:

Points, (-3, -4) and (6, -10)

The equation of the line in slope-intercept form is written as,
y = mx + b

The slope of the line is calculated as,

m = (y2 - y1) / (x2 - x1)

m = (-10 - (-4)) / (6 - (-3))

m = -6 / 9

m = -2/3

For given function function f(x)=-x+3-2, the domain is x > -3 and the range is y ≤ 2. So, correct option is D.

The function f(x)=-x+3-2 is a linear function in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is -1 and the y-intercept is 1. Therefore, the graph of the function is a straight line that intersects the y-axis at (0,1) and has a slope of -1, meaning that it decreases by 1 for every 1 unit increase in x.

The domain of the function is the set of all possible values of x for which the function is defined. Since there are no restrictions on the value of x in the equation f(x)=-x+3-2, the domain is all real numbers, or (-∞, ∞).

The range of the function is the set of all possible values of y that the function can output. In this case, the lowest possible value of y occurs when x approaches positive infinity, and the highest possible value of y occurs when x approaches negative infinity. Therefore, the range is all real numbers less than or equal to 2, or y ≤ 2.

So, the domain is x ∈ (-∞, ∞) and the range is y ≤ 2. Alternatively, the domain can also be expressed as x > -3, since that is the minimum value of x at which the function is defined.

Correct option is D.

Answer:

h(t) = 11 * sin(π/6 * t) + 15

Step-by-step explanation:

To find the height function h(t) for the piece of gum, we'll use a sinusoidal function since the height of the gum changes in a periodic manner as the tire rotates. The general formula for a sinusoidal function is:

h(t) = A * sin(B * (t - C)) + D

where A is the amplitude, B is the angular frequency, C is the horizontal shift, and D is the vertical shift.

1. Amplitude (A): The amplitude is half the distance between the highest and lowest points of the gum. Since the diameter of the tire is 22 inches, the radius is 11 inches. Thus, the amplitude is 11 inches.

2. Angular frequency (B): Since the gum completes 1 full revolution in 12 seconds, the period of the function is 12 seconds. The angular frequency, B, is found by dividing 2π by the period: B = 2π / 12 = π/6.

3. Horizontal shift (C): Since the gum starts at the three o'clock position, and we want the height to be at its maximum at t = 0, there is no horizontal shift. So, C = 0.

4. Vertical shift (D): The platform is 4 inches above the ground, and the radius of the tire is 11 inches. Therefore, the midpoint of the gum's motion is 4 + 11 = 15 inches above the ground. So, D = 15.

Now we can write the height function h(t):

h(t) = 11 * sin(π/6 * t) + 15

The solution to all parts from a to f is shown below.

A) Matrix A:

C) Matrix X:

[ -34  3 ]

D) The determinant of matrix X is:

det(X) = (-8*3) - (-3*-34) = -24 - 102 = -126

E) Matrix Y:

[ 2  -8 ]

[ 4  -34 ]

F) The determinant of matrix Y is:

det(Y) = 2(-34) - (-8) (4) = -68 + 32 = -36

G) Using Cramer's rule, we can solve for x and y as follows:

x = det(X) / det(A) = -126 / 18 = -7

y = det(Y) / det(A) = -36 / 18 = -2

To answer the questions:

a. To find the number of students who read comics and novel only (region A), we need to add up the number of students who read both comics and novel (5) and subtract from it the number of students who also read textbook (2).

So, the number of students who read comics and novel only is 5 - 2 = 3.

b. To find the number of students who read textbook and novel only (region B), we follow the same process.

We add up the number of students who read both textbook and novel (3) and subtract from it the number of students who also read comics (2).

So, the number of students who read textbook and novel only is 3 - 2 = 1.

c. To find the number of students who read none of the three categories, we start with the total number of students (50) and subtract from it the number of students who read at least one category.

To find the latter number, we add up the number of students who read only novel (3), only comics (9), only textbook (2), and all three (5), which gives us 19. So, the number of students who read none of the three categories is 50 - 19 = 31.

Answer:

AB = 90° , AC = BC = 135°

Step-by-step explanation:

the arc AB is equal to the measure of the central angle it subtends, then

AB = 90°

the sum of the arcs in a circle = 360° , then since AC and BC are congruent

AB + AC + BC = 360° ( since AC = BC ), then

90° + 2AC = 360° ( subtract 90° from both sides )

subtract 90° from both sides

2AC = 270° ( divide both sides by 2 )

AC = 135°

since AC = BC , then

AC = BC = 135°

The length of the hypotenuse is 7m.

Let the side opposite to 30° be the shortest leg.

The side opposite to 60° is the longest leg.

So, the side opposite to 90° is hypotenuse.

Length of the shortest side is x.

Length of longest side is [tex]\sqrt{3}x[/tex]

Length of the hypotenuse is 2x.

We know x = 7

So, [tex]\sqrt{3}(x)=\sqrt{3}(7)[/tex]

Thus, the length of the longer leg is [tex]\sqrt{3}(7)[/tex] m

Length of hypotenuse = 2x = 2(7) = 14m

[tex]x^{2} +(\sqrt{3} x)^2 =(2x)^2\\\\(7)^2+(\sqrt{3} (7))^2=(2x)^2\\\\49 + (3(49)) = (2x)^2\\\\49 + 147= (2x)^2\\\\(2x)^2=196[/tex]

Taking square root on both sides:

[tex]2x = \sqrt{196}[/tex]

2x = 14

x = 7

If Olivia followed either of those two methods, then she is correct. Both Angelica and Michael have incorrect methods.

Problem 1

One method Olivia could have used is to reflect over the x axis and then translate 10 units to the right.

Let's apply this set of steps to point C.

C = (-2,-4)

C' = (-2,4) after reflecting over the x axis; y coordinate flips in sign

C'' = (8,4) after shifting to the right 10 units; add 10 to the x coordinate

Point C(-2,-4) moves to C''(8,4) which is shown in the diagram. I'll let you check the other four points.

-----------

Another method Olivia could have used is to shift to the right 10 units first, then reflect over the x axis. In this case, the order doesn't matter. Though for some other combinations of transformations, order does matter.

============================================================

Problem 2

Reflecting over the y axis will have the point (x,y) turn into (-x,y). Only the x coordinate changes, and we flip the sign here. The y coordinate stays the same.

A point like C(-2,-4) becomes C'(2,-4) after the y axis reflection. Shifting up 8 units means we add 8 to the y coordinate to arrive at C''(2,4) but this does not match what the diagram shows. Therefore, Angelica's method is incorrect.

You should find other inconsistencies for the other four points as well.

============================================================

Problem 3

Michael's method isn't correct either. He does not apply an x axis reflection and instead relies entirely on translations to move ABCDE to A''B''C''D''E''

At a quick glance, it looks like Michael may be correct. But upon a much closer look, you'll see that things don't line up perfectly.

Instead of point C, we'll pick on point D this time.

D is located at (-6,-2). If we shift up 8 units, then we add 8 to the y coordinate to get to D'(-6,6). Then add 10 to the x coordinate to shift 10 units to the right. This leads us to D''(4,6).

However, the diagram shows D'' is actually at (4,2)

Feel free to examine the remaining points. It will become apparent that merely C and E are accurately plotted; however, the others are not. This is, once again, due to Michael's failure in implementing an x-axis reflection.

The A''B''C''D''E'' diagram he produced is essentially inverted compared to its intended form.

============================================================

To summarize, the methods described in problem 1 are the correct way to get ABCDE to move to A''B''C''D''E''.
