The correct graph of the relationship is shown in Option D.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Mr. Mole left his burrow that lies below the ground and started digging his way at a constant rate deeper into the ground.

Now, Let y represent Mr. Mole's altitude (in meters) relative to the ground after x minutes.

Hence, The graph of line goes down with constant rate.

Thus, The correct graph of the relationship is shown in Option D.

Answer:

Step-by-step explanation:

The function will be linear if the differences in y-values are proportional to the differences in x-values. The constant of that proportionality is the slope of the line. A linear equation can be written using the point-slope form:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

__

Table 1

x-differences: 2-0 = 2, 4-2 = 2, 6-4 = 2

y-differences: -19-6 = -25, -44-(-19) = -25, -69-(-44) = -25

m = -25/2; (h, k) = (0, 6)

  linear relation: y -6 = (-25/2)x

__

Table 2

x-differences: 2, 4, 2

y-differences: 10, 20, 10

m = 10/2 = 20/4 = 10/2 = 5; (h, k) = (2, 13)

  linear relation: y -13 = 5(x -2)

__

Table 3

x-differences: 2, 2, 2

y-differences: 20, 20, 20

m = 20/2 = 10; (h, k) = (2, -4)

  linear relation: y +4 = 10(x -2)

[tex]4 \times 3 = 12 \\ 5 \times 3 = 15 \\ 6 \times 3 = 18 \\ 7 \times 3 = 21 \\ \\ y = 3 \times x[/tex]

Step-by-step explanation:

first finding the area of the triangle by Heron's formula.

s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.

s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .

Now, the Heron's formula : √s(s-a)(s-b)(s-c)

> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]

we have use √2's value ; 1.414 to simplify.

please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,

> √196.0000 > 14(units)².

Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.

Area = ½(base)(height)

=>14= ½(7)h. (after cross multiplication)

=>(14×2)/7=h. (after cancellation)

=>2×2=h.

=> 4units = h.

Therefore, CM that is the height is 4units.

I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.

Answer: You can have 7 different 2/3 Pieces

Step-by-step explanation:

The reason you can have more than the amount of feet is because each cut is less than one foot.

Answer:

Point A is -0.5

Point B is 0.75

Point C is -1.75

If y = -0.025x^2 + 4x, then

y' = -0.05x + 4

Set y' = 2:

2 = -0.05x + 4

-2 = -0.05x

40 = x

Go back to y to find the point:

y = -0.025(40)^2 + 4(40) = 120

So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.

Answer:

  21.1%

Step-by-step explanation:

Adding 402 g of salt to a solution whose volume is 130 × 100 mL will increase the concentration by (402/130)%, or about 3.09%.

When the concentration of 18% has 3.09% added to it, the concentration of the new mixture is about 21.1%.

_____

Additional comment

We understand the units of concentration used here to be (1 g)/(100 mL) = 1%. These units are often used for a solution with a dissolved solid.
