Plz help with this problem!<br><br> x^4 + x^2 + 1
TEA [102]

Answer:

You cannot simplify this problem down anymore; it is at its simplest form.

Step-by-step explanation:

You cannot add together x^4 and x^2 due to the simple fact that they do not share similar exponents.

For example you could add together x^4 and x^4 to get 2x^4. But you cannot add x^4 and x^2.

cynthia invests some money in a bank which pays 5% compound interest per year. She wants it to be worth over £8000 at the end of
exis [7]

Answer:

The smallest amount is \£6,911

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=3\ years\\ A=\£8,000\\ r=5\%=5/100=0.05\\n=1  

substitute in the formula above

8,000=P(1+\frac{0.05}{1})^{1*3}  

solve for P

8,000=P(1.05)^{3}  

P=8,000/(1.05)^{3}  

P=\£6,910.70  

Round to the nearest pound she can invest

The smallest amount is \£6,911

  • Given this, there can be a relationship between the ideological group and the support of the moderate consideration act.
  • that various ideological groups may support various types of government disability conspiracies and might have various goals.
  • A few gatherings might focus on a list of topics or problems and might provide serious thought at some random time.
  • which might facilitate the implementation of the Affordable Care Act, while others would be gradually forgiving toward such arrangements.

Fiona's Fashion Store is world renowned for its buttoned uniforms. A collection of 36 shirts and 42 jackets contains 842buttons.
Oduvanchick [21]
To solve the problem, what you must do is a system of two equations with two Ingonites that describe the problem.
 Let:
 x = number of shirt buttons.
 y = number of buttons on jackets.
 Writing the system:
 36x + 42y = 842
 6x + 7y = 137
 We observe that the system is linearly dependent, therefore, it can not be solved.
 However, the solution is to solve the system of two equations with two unknowns.
In order to solve it, the system must be linearly independent.
