Answer:

(C) 8x^{a+b} + 4x^{a+3} - 10x^{a+1}

Step-by-step explanation:

-2x^a(-4x^b -2x^3 +5x)=-2x^a(-4x^b)-2x^a(-2x^3)-2x^a(5x)=\\\\=8x^{a+b} + 4x^{a+3} - 10x^{a+1}

Answer: The correct option is

(C) 8x^{a+b}+4x^{a+3}-10x^{a+1}.

Step-by-step explanation:  We are given to find the following product :

P=-2x^a(-4x^b-2x^3+5x)~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following property of exponents :

x^a\times x^b=x^{a+b}.

From (i), we get

P\\\\=-2x^a(-4x^b-2x^3+5x)\\\\=(-2x^a)\times(-4x^b)-2x^a\times(-2x^3)-2x^a\times5x\\\\=8x^{a+b}+4x^{a+3}-10x^{a+1}.

Thus, the required product is 8x^{a+b}+4x^{a+3}-10x^{a+1}.

Option (C) is CORRECT.

Answer:

The correct option is A.

Step-by-step explanation:

The given number is

\frac{5}{11}

Where 5 is dividend and 11 is divisor.

Since dividend is less than divisor we add a decimal place and the first zero. Notice the decimal point which has appeared on the answer line and by the dividend. It does not appear anywhere else.

Now the dividend is 50. Divide the number by divisor.

11\times 4=44

Subtract 44 from 50.

50-44=6

Therefore remainder is 6. Place a zero after 6.

Now the new dividend is 60. Divide the number by divisor.

11\times 5=55

Subtract 55 from 60.

60-55=5

Therefore remainder is 5.

\frac{5}{11}=0.454545

\frac{5}{11}\approx 0.45

Therefore option A is correct.

Compounded anually means
if you put x in at y percent then 
you calculate like this
if you put in x at y percent then  the money you earn is
x +(x times y)=z=first year
second year=z+(z times y)=s
third year=s+(s times y)=t

percent means parts out of 100 so 5%=5/100=0.05
'of' can be translated as multiply
so

3000 +(3000 times 0.05)=3150=fisrt year
3150+(3150 times 0.05)=3307.5=second year
3307.5 +(3307.5 times 0.05)=3472.88=tird year

he will have 3472.88  at end of 3 years

hammer [34]
The answer would be positive if all 3 signs were the same. Yes, the product of two integers with the same sign will be positive, but that goes for any number of integers as long as they still have the same sign.
