Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n

1)4a^3-2b^2+5= 4* 3^3 - 2*(-2)^2+5= \\ \\ =4*27-2*4+5= \\ \\ =108-8+5= \\ \\ =100+5 \\ \\ =\boxed{105}

2) 33*35=1155

A= 3⁻²= 1/3²= 1/9

B=3²=9

C=3⁸= 6561

D=3¹⁵=  14.348.907

The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legi
Romashka [77]

Answer:

We can not solve for a unique cost for each soldier.

Step-by-step explanation:

Let x be the daily cost for legionaries and y be the daily cost for archers.  

Upon using our given information we will get a system of linear equations as:

3x+3y=10...(1)

x+y=3...(2)

Now we will solve for x from our 2nd equation,

x = 3-y

Now we will substitute this value in our 1st equation.

3(3-y)+3y=10

9-3y+3y=10

We can see that -3y cancels out with 3y  and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.

xz_007 [3.2K]
The formula is
A=p (1+r)^t
A future value 572.6
P present value 560
T time 6/12 =1/2=0.5
R interest rate?
We need to solve for r
R=(A/p)^(1/t)-1
R=(572.6÷560)^(1÷0.5)−1
R=0.0455×100
R=4.55%
