Algebra

Since the numbers are the same, you are allowed to add the exponents.

{7}^{7}  \times  {7}^{3}  =  {7}^{10}

Answer:

7^{10}

Step-by-step explanation:

The laws of exponents state that if two terms share a base they can be simplified. Specifically, the product exponent law says that if 2 like bases are being multiplied then the exponents can be added together. So, because the two bases are like and 7+3=10, the final answer is 7^{10}.

The infinite geometric sum formula can be used to write 0.126126126...as a fraction. What is the numerator of this reduced fract
Kryger [21]

Answer:

B. 14

Step-by-step explanation:

The sum of infinite geometric series is given by

\frac{a}{1-r}

0.126126126... = \frac{126}{1000}+\frac{126}{1000000}+\frac{126}{1000000000}

Here a =126/1000, r= 1/1000

0.126126126... = \frac{126/1000}{1-1/1000} =126/999 = 14/111

∴ 0.126126126... = 14/111

So, the numerator of the reduced fraction is 14.

Find the 13th term of the arithmetic sequence whose common difference is d=7 and whose first term is a1=-3
timama [110]

Answer:

81

Step-by-step explanation:

the formula for an arithmetic sequence:

aₙ = a₁ + (n-1)d

where aₙ = the nth term

a₁ = the 1st term = -3

n = the term number = 13

d = the common difference = 7

Plugging in those values into the formula to find a₁₃:

a₁₃ = -3 + (13-1)7

= -3 + (12)7

= -3 + 84

= 81

Y=−5x+7 coordinates of x intercept
Allushta [10]

Answer:

The x intercept is (7/5,0)

Step-by-step explanation:

y=−5x+7

To find the x intercept, set y=0 and solve for x

0 = -5x+7

Subtract 7 from each side

0-7 = -5x+7-7

-7 = -5x

divide each side by -5

-7/-5 = -5x/-5

7/5 =x

The x intercept is (7/5,0)
