Answer:

800 centimeters:))

There is 800 cm in the room.

To convert a meter measurement to a centimeter measurement, multiply the length by the conversion ratio. The length in centimeters is equal to the meters multiplied by 100.

How many centimeters is the room?

A room is 8 meters long.

A room is 1 meter long = 100cm

A room is 8 metres long = 8*100cm = 800 cm.

428,000

Step-by-step explanation:

427,963

If the number behind what number you're trying to round is greater than 4 then the number you're rounding goes up once while everything behind it goes to zero. If it's below 5 than the it well stay the same. Ex. Round nearest tenth--> 14--->10  instead of it going up to 20 it stays 10.

427,963

      ^

This number is higher than 4 so the number in front or the thousand mark goes up a number.

1/2 is the slope

Step-by-step explanation:

By using the graph provided, you can count the lines and go up 1 and over 2. Hope this helped!

Given:

[tex]y=2x^2-8x-10[/tex]

To find:

The interval(s) on which the given function is positive.

Solution:

We have,

[tex]y=2x^2-8x-10[/tex]

[tex]y=2(x^2-4x-5)[/tex]

[tex]y=2(x^2-5x+x-5)[/tex]

[tex]y=2(x(x-5)+1(x-5))[/tex]

[tex]y=2(x+1)(x-5)[/tex]

For zeroes, [tex]y=0[/tex]

[tex]2(x+1)(x-5)=0[/tex]

[tex]x=-1,x=5[/tex]

-1 and 5 divide the number line in three parts [tex](-\infty , -1),(-1,5),(5,\infty )[/tex].

Interval        Selected Value      [tex]y=2(x+1)(x-5)[/tex]                      Sign

[tex](-\infty,-1)[/tex]                -2                  [tex]y=2(-2+1)(-2-5)=14[/tex]           +

[tex](-1,5)[/tex]                     0                   [tex]y=2(0+1)(0-5)=-10[/tex]              -

[tex](5,\infty)[/tex]                       6                  [tex]y=2(6+1)(6-5)=14[/tex]                 +

So, the function is positive for interval [tex](-\infty,-1)[/tex] and [tex](5,\infty)[/tex].

We can say that the function is positive for interval x < -1 and x > 5.

Therefore, the correct option is B.

Answer:

-1.4

Step-by-step explanation:

There are five increments between -2 and -1, so we find the difference between -2 and -1, which is 1. Divide 1 by five (increments)=.2

This means that every increment is worth 0.2.

If we see it from the left to right, from -2, there are 3 increments to the right, so multiply three by 0.2 which is 0.6, add 0.6 to -2, which is -1.4.

Answer:

5518

Step-by-step explanation:

Answer:

7.071inches

Step-by-step explanation:

The set up is a right angled triangle

Given 'angle of elevation = 45 degrees

The length of the frame = 10in (hypotenuse)

Required

Height of the truck h (opposite)

Using the SOH trig identity

sin theta = opposite/hyp

sin 45 = h/10

h = 10sin45

h = 10(0.7071)

h = 7.071 in

Hence the height of the truck is 7.071inches

Answer:

swings: 120 (50%)

obstacle course: 80 (1/3)

sandbox: 40

Step-by-step explanation:

we know by looking, that swings makes up 50%, so we divide 240 by 2 to get 120

the obstacle course makes up one-third, 1/3 of 240 is 80

add 120+80 to get 200

to find the sandbox amount, do 240 minus 200 and we get 40

The circle graph is used to show how variables measure against one another using a circle of different sectors.

There are 40 residents in sandbox, 80 in obstacle course, and 120 in the swings

The number of residents is given as:

[tex]n = 240[/tex]

From the given circle graph, we have the following proportions

[tex]Sandbox = 1/6n[/tex]

[tex]Obstacle = 1/3n[/tex]

[tex]Swings= 1/2n[/tex]

So, the number of residents in each equipment is:

[tex]Sandbox = \frac 16 \times 240[/tex]

[tex]Sandbox = 40[/tex]

[tex]Obstacle = \frac 13 \times 240[/tex]

[tex]Obstacle = 80[/tex]

[tex]Swings =\frac 12 \times 240[/tex]

[tex]Swings =120[/tex]

Hence, there are 40 residents in sandbox, 80 in obstacle course, and 120 in the swings

Answer:

46 of the sixth graders have green eyes.

Step-by-step explanation:

This question is asking what number of the 230 sixth graders have green eyes.

We know that one out of every five of them, or 20%, have green eyes.

1/5 = 0.2

If we multiply 0.2 by the total number of sixth graders, that leaves us with 46, meaning that 46/230 sixth graders have green eyes.

Answer:

(14 , -7)

Step-by-step explanation:

terminal points: A (-6,3)   B (4,-2)

u = x₁ + i y₁    u = -6 + i3

v =x₂ + iy₂ = 4 - i2       2v = 8 - i4

2v - u = (8 - i4) - (-6 + i3) = 14 -i7

Resulting terminal point: (14 , -7)

Position vectors u and v have terminal points of (-6, 3) and (4, -2), respectively. Find the resulting terminal point of 2v - u.
