Answer:

When a point is reflected across the x axis, it has the same x axis but the y axis is multiplied by -1. Think about the x axis as a mirror and the point is projected across the x axis.

Hence the x coordinate is -1 and the y coordinate is -5.

The total cost of trip for 37 people will be $1194.

Step-by-step explanation:

Given,

Rent of bus = $750

Cost of one ticket = $12

Let,

x be the number of people.

T be the total cost of the trip for people.

According to given statement;

Total cost = Rent of bus + (Cost of one ticket * number of people)

[tex]T=750+12x[/tex]

For 37 people, x=37

[tex]T=750+12(37)\\T=750+444\\T=\$1194[/tex]

The total cost of trip for 37 people will be $1194.

Answer:

20.8

Step-by-step explanation:

Using Pythagorean theorem, you can find 1/2 of x.

12²= 6² +1/2x²

From this we find 1/2 x is ≈ 10.4

Then x itself would be 2 times that, resulting in 20.8, that is your answer

Answer:

FG = 47

Step-by-step explanation:

The opposite sides of a parallelogram are parallel and congruent, thus

EH = FG, that is

5z - 18 = 3z + 8 ( subtract 3z from both sides )

2z - 18 = 8 ( add 18 to both sides )

2z = 26 ( divide both sides by 2 )

z = 13

Hence

FG = 3z + 8 = (3 × 13) + 8 = 39 + 8 = 47

Based on the property of a parallelogram, the measure of FG is: 47.

Based on the properties of a parallelogram, the opposite sides of a parallelogram are equal in length.

Therefore:

EH = FG

5z - 18 = 3z + 8

5z - 3z = 18 + 8

2z = 26

z = 13

FG = 3z + 8

FG = 3(13) + 8

FG = 47

Answer:

The maximum height reached by the golf ball when v = 35 is 24.5 meters.

Step-by-step explanation:

Given : A golf ball, thrown upwards, rises at a speed of v metres per second. The ball reaches a maximum height of h metres.  h is proportional to the square of v.  When v = 20, h = 8.

To find : Work out the maximum height reached by the golf ball when v = 35 ?

Solution :

h is proportional to the square of v i.e. [tex]h\propto v^2[/tex]

[tex]h=kv^2[/tex]

Where, k is the constant of proportionality

When v = 20, h = 8,

[tex]8=k(20)^2[/tex]

[tex]8=400k[/tex]

[tex]k=\frac{8}{400}[/tex]

[tex]k=0.02[/tex]

The equation became [tex]h=0.02v^2[/tex].

Now, when v = 35 the value of h is

[tex]h=0.02(35)^2[/tex]

[tex]h=0.02\times 1225[/tex]

[tex]h=24.5[/tex]

Therefore, the maximum height reached by the golf ball when v = 35 is 24.5 meters.

Answer:

x<-8

Step-by-step explanation:

four more than twice a number = 4+2X

is less than negative twelve = <-12

4+2X<-12

(4-4)+2X< -12-4

2x<-16

X<-8

To find the numbers that make the statement true, we need to solve the equation 2x + 4 < -12 for x. Any number less than -8 will make the statement true.

To find the numbers that make the statement true, we need to translate the given sentence into a mathematical equation. Let's denote the unknown number as 'x'. The sentence 'Four more than twice a number is less than negative twelve' can be written as 2x + 4 < -12. Now, we can solve this equation for x:

Subtracting 4 from both sides, we get 2x < -16.

Dividing both sides by 2, we have x < -8.

Therefore, any number less than -8 will make the statement true.

Answer:

5/9

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

Now we need to make our denominators match.

9 goes into 3 evenly, so we only need to multiply one term to get a common denominator.

Multiply 1 by 3, and get 3, then we multiply 3 by 3 and get 9.

Since our denominators match, we can add the numerators.

2 + 3 = 5

That gives us the sum, which is

5/9

Now, do we need to simplify this fraction?

First, we attempt to divide it by 2...

Nope! So now we try the next greatest prime number, 3...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

No good. 7 is larger than 5. So we're done reducing.

There you have it! Here's the final answer to 2/9 + 1/3

Correct option:

c.f(x-3)+1

From the options we have either vertical or horizontal shift. So, for this type of transformation we have:

For any real positive number [tex]c[/tex], vertical and horizontal shift in the graph [tex]y=f(x)[/tex] are expressed as follows:

[tex]\bullet \ Vertical \ shift \ c \ units \ \mathbf{upward}: \\ h(x)=f(x)+c \\ \\ \bullet \ Vertical \ shift \ c \ units \ \mathbf{downward}: \\ h(x)=f(x)-c \\ \\ \bullet \ Horizontal \ shift \ c \ units \ to \ the \ right \ \mathbf{right}: \\ h(x)=f(x-c) \\ \\ \bullet \ Horizontal \ shift \ c \ units \ to \ the \ left \ \mathbf{left}: \\ h(x)=f(x+c)[/tex]

From these rules, we know that:

[tex]f(x-3)+1[/tex]

would move the graph of the function to the right of the coordinate plane because of [tex]f(x-3)[/tex]. In other words, the transformation is as follows:

[tex]f(x-3)+1[/tex] shifts the graph of [tex]f(x)[/tex] three units to the right and one unit up

The height of the observer can be taken negligible in case of big measurements. The height of the kite from the ground is 40 meters approximately.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Referring to the figure attached below, we have the vertical distance of the kite from the ground as the length of the side BC.

(assume that the height of the observer flying kite is negligible and that kite's string is straight, and some more basic assumptions)

Using the Pythagoras theorem as the triangle ABC is a right angled triangle as vertical distance means line perpendicular to the ground, we get the length of the line segment BC as:

[tex]|AC|^2 = |AB|^2 + |BC|^2\\\\|BC|^2 = |AC|^2 - |AB|^2\\\\|BC| = \sqrt{|AC|^2 - |AB|^2}\\[/tex]

(positive root since length is a non-negative quantity).

We have |AC| = length of the kite's string = 50 meters

|AB|  = distance of the observer from the point directly above which the kite is flying = 30 meters

Thus, we get the height of the kite from the ground as:

[tex]|BC| = \sqrt{|AC|^2 - |AB|^2}\\|BC| = \sqrt{50^2 - 30^2} = \sqrt{1600} = 40\: \rm \text{(in meters)}[/tex]

Thus,  the height of the kite from the ground is 40 meters approximately.

Answer:

The numbers are 40 and 49

Step-by-step explanation:

Smaller number = x

Larger number = y

Let's write our system of equations:

x + y = 89

3x = y + 71

***************************

x = 89 - y

Substituting x in the 2nd equation and solving for y:

3 (89 - y) = y + 71

267 - 3y = y + 71

-3y - y = 71 - 267 (Like terms)

-4y = - 196

y = -196/-4

y = 49

Solving for x in the 1st equation:

x + y = 89

x + 49 = 89

x = 89 - 49

x = 40

The numbers are 40 and 49
