Answer:

x = 0, π/3, π, 5π/3, 2π

Step-by-step explanation:

2sinxcosx = sinx

2sinxcosx - sinx = 0

sinx(2cosx - 1) = 0

sinx = 0, 2cosx-1 = 0

sinx = 0

x = 0, π, 2π

cosx = ½

basic angle = π/3

x = π/3, 2π - π/3 = 5π/3

x = 0, π/3, π, 5π/3, 2π

Tanzania [10]

Answer:

Mercantilism is an economic policy that is designed to maximize the exports and minimize the imports for an economy. It promotes imperialism, tariffs and subsidies on traded goods to achieve that goal

Import is to bring in (merchandise, commodities, workers, etc.) from a foreign country for use, sale, processing, reexport, or services.

Export is to ship (commodities) to other countries or places for sale, exchange, etc.

enumerated article is under the English navigation Acts, those commodities that could be shipped only to England or other English colonies; originally included sugar, tobacco, cotton, and indigo.

legislature is a deliberative body of persons, usually elective, who are empowered to make, change, or repeal the laws of a country or state; the branch of government having the power to make laws, as distinguished from the executive and judicial branches of government.

An indentured servant or indentured laborer is an employee (indenturee) within a system of unfree labor who is bound by a signed or forced contract (indenture) to work without pay for the owner of the indenture for a period of time

The Navigation Acts, or more broadly the Acts of Trade and Navigation, was a long series of English laws that developed, promoted, and regulated English ships, shipping, trade, and commerce between other countries and with its own colonies.

The Dominion of New England in America was an administrative union of English colonies covering New England and the Mid-Atlantic Colonies.

The English Bill of Rights was an act signed into law in 1689 by William III and Mary II, who became co-rulers in England after the overthrow of King James II. The bill outlined specific constitutional and civil rights and ultimately gave Parliament power over the monarchy

The polynomial function f(x) = 3x5 – 2x2 + 7x models the motion of a roller coaster. The roots of the function represent when th
cupoosta [38]

Answer:

x=0

Step-by-step explanation:

We have been given that a polynomial function f(x)=3x^{5}-2x^{2}+7x models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.

In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:

f(x)=3x^{5}-2x^{2}+7x\\f(x)=x(3x^{4}-2x+7)\\

The zeroes of this polynomial occur when either x=0 or 3x^{4}-2x+7=0.

The equation 3x^{4}-2x+7=0 have no real solutions. Therefore, the only time when the roller coaster is at the ground is at x=0

What is the percent increase?Original quantity:50 new quantity 56
Semmy [17]

Answer:

This is a 12% change

Step-by-step explanation:

To find the percent change, use the percent change equation.

(New - Old)/(Old) * 100 = Percent Change

(56 - 50)/(50)*100 = Percent Change

6/50 * 100 = Percent Change

.12 * 100 = Percent Change

12% = Percent Change
