Answer:

geometric sequences are given below

1,3,9,27,81

5,10,20,40,80,160

10,5,205,1.25,0.625,0.3125

Step-by-step explanation:

geometric sequences are those sequences whose common ratio are same

so that \frac{3}{1}=\frac{9}{3}=\frac{27}{9}=\frac{81}{27}

           \frac{10}{5}=\frac{20}{10}=\frac{40}{20}=\frac{80}{40}=\frac{160}{80}

\frac{5}{10}=\frac{2.5}{5}=\frac{1.25}{2.5}=\frac{0.625}{1.25}=\frac{0.3125}{0.625}

1,3,9,27,81

5,10,20,40,80,160

10,5,2.5,1.25,0.625,0.3125

these are in geometric sequences

Firlakuza [10]

Answer:

x = 6.6

Step-by-step explanation:

Data obtained from the question include the following:

Angle X = 15°

Angle Y° = 23°

Side y = 10

Side x =..?

The value of side x can be obtained by using the sine rule as shown below:

x/Sine X = y/Sine Y

x/Sine 15 = 10/Sine 23

Cross multiply

x × Sine 23 = 10 × Sine 15

Divide both side by Sine 23

x = (10 × Sine 15) / Sine 23

x = 6.6

Therefore, the value of x is 6.6.

Take any three digit number. Reverse its digits and subtract the smaller of the two numbers from the larger. Determine what numb
rjkz [21]

Answer: 11 is the required number that always divides such differences for the following types of numbers.

Step-by-step explanation:

Take any 3 - digit number, say, 325

On reversing its digit it becomes, 523

On subtracting the smaller of the two numbers from the larger,523-325\\\\=198

we can see that 198 is an even number.

take another number say, 629

On reversing its digit, it becomes = 926

On subtracting , we get that

926-629=297

But 297 is not an even number.

But there is one common in both the cases is that both the differences are divisible by 11.

Hence, 11 is the required number that always divides such differences for the following types of numbers.

In your own words, explain why when we multiply terms that have the same bases, we add the exponents.
Doss [256]

When multiplying exponents, remember the first rule: when multiplying similar bases, add powers together. 52% + 56% =? The bases of the equation remain unchanged, while the exponents' values are added together. Adding the exponents is only a quick way to get at the answer. Simply add the exponents to multiply exponential expressions with the same base. Simplify. The product rule applies because the base of both exponents is a. With a common basis, add the exponents.
