A box is made of wood with its external dimensions of 154 cm x 100 cm x 84 cm and thickness of 2 cm.
How much wood was used to make it?

Step-by-step explanation:

f(x) = —x^2 – 3x

f(10)={-10}²-3×10=100-30=70

Answer:

f(10) = 70

Step-by-step explanation:

In this question, plug in "10" to "x" and solve.

Solve:

f(10) = -(10)^2 - 3(10)

f(10) = 100 - 3(10)

f(10) = 100 - 30

f(10) = 70

Your final answer would be f(10) = 70

Step-by-step explanation:

Answer:

[tex]y-1=6(x+5)[/tex]

Step-by-step explanation:

The given point is (-5, 1) and the slope is 6.

Point-slope form is given by:

[tex]y-y_1=m(x-x_1)[/tex]

We will let (-5, 1) be (x₁, y₁) and we will substitute 6 for m. Therefore:

[tex]y-(1)=6(x-(-5))[/tex]

Simplify:

[tex]y-1=6(x+5)[/tex]

Answer:

-1/36

Step-by-step explanation:

18=-1/(2k)

2k=-1/18

k=(-1/18)/2

k=(-1/18)(1/2)

k=-1/36

Answer:

Infinitely many solutions.

Step-by-step explanation:

Multiply the second equation by -2, then add the equations together

(20x+2y=18)

−2(10x+y=9)  

20x+2y=18

−20x−2y=−18

Add these equations to eliminate x

0=0

Infinitely many solutions.

Answer:

1.918

Step-by-step explanation:

1 then do 459/500 x 2 to make 918/1000 then add and convert

Answer:

Alternate Interior ∠s: 3 & 5, 4 & 6.

Corresponding ∠s: 1 & 5, 2 & 6, 3 & 8, 4 & 7.

Alternate Exterior ∠s: 1 & 8, 2 & 7.

Consecutive ∠s: 3 & 6, 4 & 5.

Step-by-step explanation:

Alternate interior angles must both be in between the parallel lines, it is almost like you are flipping the angle over the line, then moving it down, if that makes any sense.

Corresponding angles correspond, which means that they are the same (of course), but it is like you go directly down to the similar angle. You can visually see that angles are the same, an example is 1 & 5.

Alternate exterior angles are similar to alternate exterior angles, but they must be on the exterior of the parallel lines. Once again, it is like you are flipping the angle of the line, then turning it downwards, if it makes any sense that way to you.

Consecutive angles are always in between the two parallel lines on the same side. They add up to 180. So 4 & 5 is a good example.

Good luck.

Answer:

In this case, the side lenghths don't even form a triangle. Since that is not an option, the triangle would be acute.

Step-by-step explanation:  

if c^(2 )> a^(2)+b^(2) then the triangle is obtuse.

if c^(2 )< a^(2)+b^(2) then the triangle is acute.

if c^(2 )= a^(2)+b^(2) then the triangle is right

Hope this helps :)

Answer:

[tex]\vec v = 2\cdot \vec a = \langle -4,6 \rangle[/tex]

Step-by-step explanation:

Let [tex]\vec a = \langle -2, 3 \rangle[/tex], we need to determine [tex]\vec v = 2\cdot \vec a[/tex], which can be found by applying the following property:

[tex]\alpha \cdot \langle x,y \rangle = \langle \alpha \cdot x, \alpha \cdot y\rangle[/tex], [tex]\forall \,\alpha,x,y\in \mathbb{R}[/tex] (1)

Then,

[tex]\vec v = 2\cdot \langle -2,3 \rangle[/tex]

[tex]\vec v = \langle -4,6 \rangle[/tex]

Answer: A is right. B is acute, C is obtuse, and D is right.

Step-by-step explanation:

The right triangles have the square in the corner.

Triangle C is a little bit bigger than a right triangle.

Triangle B is acute because its smaller than a right triangle.

Option 2  [tex]\frac{4\sqrt{6} }{3}[/tex]

Step-by-step explanation:

[tex]\frac{4\sqrt{2} }{\sqrt{3} } = \frac{4\sqrt{2} \sqrt{3} }{\sqrt{3}\sqrt{3} } = \frac{4\sqrt{6} }{3}[/tex]

Answer:

5.5

Step-by-step explanation:

2x -3 = 8

then

2x = 8 + 3 = 11

means

2x = 11

then

x = 11 ÷ 2

x = 5.5

___________________

we change the sign (- or +)

then take the number to the other side of the equal (with the changed sign)

leaving the x alone so that we can answer the equation..

Answer:

(-2, -1, 0, 3,3)

Step-by-step explanation:

The domain simply refers to the possible x-values the function can take

so by listing out all the x-values of the individual points, we have all the domains

That will be ;

(-2, -1, 0, 3,3)

Answer:

6 students.

Step-by-step explanation:

3v +  c = 22  ---> c = 22 - 3v

2v + 4c = 28 ---> 2v + 4(22 - 3v) = 28

                         2v + 88 - 12v = 28

                       -10v + 88 = 28

                               - 88  - 88

                        - 10v = - 60

                              v = 6 students
