Answer:

At 10:05 a.m., there are 2 microscopic bacteria cells in the bottle. How many cells will be in the bottle at 10:15 a.m.?

Step-by-step explanation:

Answer:

a = 3x

b = -6x^2

c = 4

Step-by-step explanation:

to find b we have to multiply (x - 3) with 2x^2

= 2x^3 - 6x^2

b = - 6x^2

to find a

in the second step of division to get -9x

we have to multiply x - 3 with 3x

a = 3x

to find c we have to add next term after x in the first equation that is 4

in equation 8x + 4

so c = 4

Answer:

  4 : 1

Step-by-step explanation:

Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:

The velocity of the particle at the first instance it is at the origin (approximately t ≈ 2.944) is approximately 16.885 units per time unit.

To find the velocity of the particle at the first instance it is at the origin, we need to find the value of t when x(t) = 0.

Since the particle is at the origin when x(t) = 0, we have:

[tex]0.5t^4 - 1.5t^3 - 2t^2 + 6t - 1 = 0[/tex]

Using numerical methods or graphing the equation, we find that the roots are approximately t ≈ -0.618, t ≈ 1.532, t ≈ 3.143, and t ≈ 2.944.

Since t > 0, the first instance the particle is at the origin corresponds to t ≈ 2.944 (the smallest positive real root).

Now, to find the velocity of the particle at this instance, we need to find the derivative of the position function x(t) with respect to time t, which gives us the velocity function v(t):

v(t) = dx/dt

[tex]v(t) = d/dt (0.5t^4 - 1.5t^3 - 2t^2 + 6t - 1)\\v(t) = 2t^3 - 4.5t^2 - 4t + 6[/tex]

Now, we can find the velocity at t ≈ 2.944:

[tex]v(t = 2.944) = 2(2.944)^3 - 4.5(2.944)^2 - 4(2.944) + 6[/tex]

v(t ≈ 2.944) ≈ 16.885

So, the velocity of the particle at the first instance it is at the origin (approximately t ≈ 2.944) is approximately 16.885 units per time unit.

Answer:

C. 213.65 = 12.3(I+ 4.3)​

Step-by-step explanation:

Original length: l

New length: l + 4.3

area: LW

area: 213.65 m²

area = LW = (l + 4.3)(12.3)

(l + 4.3)(12.3) = 213.65

12.3(l + 4.3) = 213.65

Answer: C. 213.65 = 12.3(I+ 4.3)​

Step-by-step explanation:

23 x 98 x 45 x 1 equals 101,430, but the real trick of the question is whether it is positive or negative.

23(-98) forms a negative number (-2,254)

-2254(-45) forms a positive number (101,430)

101,430(-1) forms a negative number (-101,430)

The two tangent theorem states that if we draw two lines from the same point which lies outside a circle, such that both lines are tangent to the circle, then their lengths are the same.

Which means that DB = CB

Which means that 10x + 16 = 5x + 20

10x - 5x = 20 - 16

5x = 4

x = 4/5

And so the length of CB is

5 * 4/5 + 20 = 4+20 = 24

The three points that represents the proportional relationship will be;

⇒ (2 , 4) (3, 6) and (5, 10)

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

The number cards are,

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Now,

Since the proportions represents the equivalent ratios.

Hence,

We can take the points which represents the equivalent ratio.

So, We get the points as;

⇒ (2 , 4) (3, 6) and (5, 10)

Because all the ratio between every points represents the equivalent ratio.

That is;

2 : 4 = 1 : 2

3 : 6 = 1 : 2

5 : 10 = 1 : 2

Therefore,

The three points that represents the proportional relationship will be;

⇒ (2 , 4) (3, 6) and (5, 10)
