Step-by-step explanation:

a majority starts at half of the total mass + 1.

so,

2,500,000 / 2 = 1,250,000

and + 1 means then the majority would be

1,250,001 shares.

Answer:

A

Step-by-step explanation:

The statement that If p → q and q are true, then p is true which is the correct answer would be an option (A).

A conditional statement is defined as the two fundamental components that make up a conditional statement are Hypothesis (if) and Conclusion (then).

Let us consider the example to understand the parts of a conditional statement.

Conditional Statement: If today is Friday, then yesterday was Thursday.

Hypothesis: "If today is Friday."

In the given problem,

Conditional Statement: If p → q and q are true, then p is true,

Hypothesis: "If p → q and q are true"

Hence, the statement that If p → q and q are true, then p is true which is the correct answer would be option (A)

Answer:

  (x -1/4)(x -1)(x +1)

Step-by-step explanation:

Pairs of coefficients have the same ratio, so it is likely that you can factor this by grouping pairs of terms.

  x³ -x -1/4x² +1/4 = (x³ -x) -(1/4x² -1/4) . . . . . . note the signs

  = x(x² -1) -1/4(x² -1)

  = (x -1/4)(x² -1)

The difference of squares (x² -1) is a special form that has factors (x -1)(x +1)

Your factoring is ...

  (x -1/4)(x -1)(x +1)

Answer:

  the average speed is 50 10/13 mph

Step-by-step explanation:

The relationship between time, speed, and distance is ...

  distance = speed × time

The distance traveled in the first part of the car's journey is ...

  (45 mi/h)(2/3 h) = 30 mi

The distance traveled in the second part of the car's journey is ...

  (60 mi/h)(25/60 h) = 25 mi

Then the total distance is 30 mi +25 mi = 55 mi.

The total time is ...

  40 min +25 min = 65 min = 65/60 h = 13/12 h

The average speed for the trip is ...

  speed = distance/time = (55 mi)/(13/12 h) = 660/13 mi/h = 50 10/13 mi/h

The average speed of the journey is 50 10/13 mi/h, just over 50 mi/h.

2) if to solve this equation, then

t=32°

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km

We are given a Triangle PQR.

In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.

In Triangle SRT, Side RT = 33 kilometers.

Using concept of ratio of similar triangles, we can say that;

ST/RT = PQ/PR

Thus;

ST = RT * (PQ/PR)

ST = 33 * (16/24)

ST = 22 Km

Answer:

Find 9% of 250 by turning 9% into a decimal.

.09 x 250 gives you 22.50

add 22.50 to 250

now you have 272.50

now find 10% of 272.50 by converting 10% into a decimal.

.10 x 272.50 gives you 27.25

Add that to 272.50 and you total cost is

Answer:

Suppose NOL -> QRM is a reflection across the x-axis. If O(-3, 8) what is the y coordinate of R?

Step-by-step explanation:

Answer:

How do I help? This scenario makes no sense

The given curve has equation

r(θ) = 9 + 8 cos(θ)

and its derivative is

dr/dθ = -8 sin(θ)

When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.

Differentiate these with respect to θ :

dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)

dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)

In polar coordinates, we have

y(θ) = r(θ) sin(θ)

x(θ) = r(θ) cos(θ)

and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.

The slope of the tangent line to the curve is dy/dx. By the chain rule,

dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)

dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))

When θ = π/3, the slope is

dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))

dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))

dy/dx = - 1/(17√3)

So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is

y - 13√3/2 = -1/(17√3) (x - 13/2)

y = -(x - 338)/(17√3)
