Answer:
Perimeter of Triangle:
Step-by-step explanation:
The perimeter is the sum of all of the sides of the triangle.
Hence, the perimeter
Since the perimeter is 90, .
Subtract 15 from both sides:
Divide both sides by 6:
Answer:
i think the answer is -18x^(2)+9x+5
-18x^(2)+9x+5
Subtract 4x^2 from −14x^2
According to the oxford dictionary, the word taxes defines as a compulsory contribution to state revenue, levied by the government on workers' income and business profits, or added to the cost of some goods, services, and transactions.
Money is taken from your yearly earnings to pay for services such as the Police, Emergancy Services, Military, Schools, Postal Service ect. It is also used to pay workers who work in a federal agency such as Postal Workers and the FBI. Citizens of the United States are taxed on items that are non-edible, such as a TV, and phones in stores. Tax percentages differ in every state.
Taxes are destributed to states so the states could build roads, schools, police stations and a lot more stuff.
The country can run Social Programs such as Social Security from taxes.
When b=0
f(x)=ax^2+c
test each
A. with x^2-1, A is false
B. with -x^2-1, B is false
C. cannot find contradiction
D. the axis is actually x=0, 0 is nithere positive nor negative, false
answer is C
Part A:
Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.
Let the length of the other side be x, then
Thus, if the length of one of the side is x, the length of the other side is 8 - L.
Hence, the area of the rectangle in terms of L is given by
Part B:
To find the domain of A
Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.
Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.
Hence the domain of the area are the set of values between 0 and 8 not inclusive.
Therefore,
