Answer:  D. Yes ; -8

Step-by-step explanation:

An arithmetic sequence is given by :-

a_1, a_2, a_3, a_4 , ........., a_n , where n is a natural number .

Here ,  differences between the successive terms is equal (d).

i.e. Common difference = d=a_2-a_1= a_3-a_2=a_4-a_3 and so on.

The given sequence : 19,11,3,-5

a_2-a_1=11-19=-8

a_3-a_2=3-11=-8

a_4-a_3=-5-3=-8

Since the differences between the successive terms are equal as -8.

So, the given sequence is an Arithmetic sequence with common difference = -8

Hence, the correct answer :  Yes , given sequence is an Arithmetic ; common difference =-8

Peter put $8,000 into a savings account that pays 6% interest, compounded continuously. After five years, Peter will have $ 8,00
Natasha2012 [34]
We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e^(r t ). We know that r = 0.06; t = 5; e = 2.71 and P = $8,000. A = 8,000 * 2.718^( 0.06 * 5 ) = 8,000 * 2,718^( 0.3 ) = 8,000 * 1.3488158 = 10,798.53. Answer:<span> B. $10,798.53.</span>

Determine the values of n
N76 [4]
<h2>Answer:</h2><h3>b. n is odd</h3><h2>Step-by-step explanation:</h2>

In this problem, we assume that n is a whole number. The definition of inverse functions tells us that a function f has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of f at more than one point. This only happens if n is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:

FIRST:

n=2 \\ \\ f(x)=x^2

Since n is even, an horizontal line will pass through two points as indicated in the first figure below.

SECOND:

n=3 \\ \\ f(x)=x^3

Since n is odd, an horizontal line will pass through just one point as indicated in the second figure below.

What’s the expression for “seven times x is no more than 15”
Andru [333]
The answer is 7x≤15 because 7 times x (7x) can't be greater than 15, so the inequality would be less than or equal to because it had to be less than or equal to 15.

Explain how to find the missing exponent given the base and the value
drek231 [11]

Answer:

To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.

On both sides, powers have the same base, so their exponents must be equal.

Step-by-step explanation:

<h3>Problem 1:</h3>

Write the missing exponent:

25=5^x

Let x be the missing exponent.

To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.

That is,

25=5*5 or 5^2

Now,

5^2=5^x

Powers have the same base so their exponent must be equal.

Hence the missing exponent is 2
