A student states that natural resources could be saved if people made everything they need in labs. What is the main problem with this idea?(1 point)
There are not enough synthetic resources yet to make what people need.
People might think it is fine to waste a lot of the materials since they just came from a lab.
The materials made in labs will still pollute the environment and destroy natural resources.
Anything made in the lab requires natural resources to produce it.

Step-by-step explanation:
We have the equation y = 2x - 5
To complete the table of values substitute each of the x values into the equation
When x = 0
y = 2(0) - 5 which means y =(2 × 0) - 5 = -5
The coordinates you plot are (0,-5)
When x = 1
y = 2(1) - 5 which means y = (2 × 1) - 5 = -3
The coordinates you plot are (1,-3)
When x = 2
y = 2(2) - 5 which means y = (2 × 2) - 5 = -1
The coordinates you plot are (2,-1)
When x = 3
y = 2(3) - 5 which means y = (2 × 3) - 5 = 1
The coordinates you plot are (3,1)
When x = 4
y = 2(4) - 5 which means y = (2 × 4) - 5 = 3
The coordinates you plot are (4,3)
When x = 5
y = 2(5) - 5 which means y = (2 × 5) - 5 = 5
The coordinates you plot are (5,5)

The formula of perimeter of a rectangle is b + b+ H + H= here they gave us 7 and 5 so we just multiply 7 by 2 and multiply 5 by 2 then add the digits together now we get 24
Answer:
24 ft
Step-by-step explanation:
To find the perimeter of a rectangle we use the formula
P = 2(l+w) where l is the length and w is the width
P = 2 ( 7+5)

A student draws three vertices of a square on the coordinate plane. The three vertices are X ( − 10 , − 1 ) , Y ( − 10 , 5 ) , and Z ( − 4 , − 1 ) . Which coordinate pair could be the fourth vertex of the square?
Answers
The coordinate pair (-4,5) could be the fourth vertex of the square.
QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus and trapezoid. Each type is defined accordingly to its length of sides and angles. For example, the square has all side equals and angles equal to 90°.
For solving this question, you should plot the given points as shown in attached image. Note that you have only two sides of a square, and you need a point (W) for completing the square.
As you have a square, all sides should have the same dimensions and all angles should equal to 90°. Therefore, the coordinates for the point W should result in equal and parallel sides XY and XZ. For this, from the attached image, you can see that the x-coordinate for the point W should be equal to the x-coordinate for the point Z. And, the y-coordinate for the point W should be equal to the y-coordinate for the point Y.
Thus, coordinate pair (-4,5) would be the fourth vertex of the square.

Yes, they are.a) The kind of design which was used to collect these data is:
Quantitative Research Design:b) The appropriate hypotheses is:
People who are depressed are more likely to die from cardiac arrest than people who are not depressed.c) Are the assumptions and conditions necessary for inference satisfied?
No, it is not. More tests and samples need to be concluded to make sure that it is not a chance occurrence.d) Test the hypothesis and state your conclusion,
The hypothesis made is consistent with the statistical data but there needs to be more observation and independent variables used.e) The best explanation of this context based on what your P-value means is:

The floor of a moving van is 3 feet off of the ground. The ramp into the van makes a 22. 3 angle with the ground. How long is the ramp?
12. 0 feet
7. 3 feet
3. 2 feet
7. 9 feet
Answers
Answer:
(d) 7.9 ft
Step-by-step explanation:
The geometry of the problem can be represented by a right triangle whose hypotenuse is the ramp, and the side opposite the given angle is 3 feet. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
Solving for Hypotenuse, we find ...
Hypotenuse = Opposite/Sin
ramp length = (3 ft)/sin(22.3°) ≈ 7.9 ft
The ramp is about 7.9 feet long.

Substitue c = 1.8 in, we get :

[tex][Hello,BrainlyUser][/tex]
Answer:
y = -8
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases.
[tex]2^3^y=2^4^(^y^+^2^)[/tex]
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
[tex]3y=4(y+2)[/tex]
Simplify
[tex]4(y+2).[/tex]
Apply the distributive property.
[tex]3y=4y+4*2[/tex]
Multiply 4 by 2
[tex]3y=4y+8[/tex]
Subtract 4y from both sides of the equation.
[tex]3y-4y=8[/tex]
Subtract 4y from 3y.
[tex]-y=8[/tex]
Multiply each term in −y=8 by −1
[tex]y=-8[/tex]
Hence, Answer is y = -8
