False as the difference between two consecutive numbers is not a constant

Ainat [17]3 years ago

Answer:

False

Step-by-step explanation:

Given sequence,

1, 2, 3, 4, 1, 2, 3, 4, .........

Since, a sequence is called Arithmetic sequence if the difference in consecutive terms is constant,

∵ 2 - 1 = 3 - 2 = 4 - 3 = 1 - 4 ≠ 2 - 1 = 3 - 2 = 4 - 3 .......

Hence, the difference in consecutive terms is not constant,

Therefore, given sequence is not an Arithmetic sequence.

Which of the following is true about the function y=4*3^x

Trava [24]

Answer:

option-c

Step-by-step explanation:

we are given

$y=4(3)^x$

we will verify each options

option-A:

we can see that exponent is over 3

and it is positive and greater than 1

so, this function is increasing

so, this is FALSE

option-C:

At x=1:

$y=4(3)^1$

$y=12$

At x=2:

$y=4(3)^2$

$y=36$

$\frac{y_2}{y_1} =\frac{36}{12}$

$\frac{y_2}{y_1} =3$

$y_2=3y_1$

So, it is getting tripled

so, this is TRUE

option-b:

we can plug x=0

$y=4(3)^0$

$y=4$

so, this is FALSE

option-d:

we can plug x=1

$y=4(3)^1$

$y=12$

so, this is FALSE

85 kilometers is equal to how many meters

Anna71 [15]

Answer:

85 kilometers is equal to 85 000 meters

Step-by-step explanation:

1 kilometer is equivalent to 1000 meters. Then to convert from kilometers to meters use the following conversion factor

$x\ kilometers * \frac{1000\ meter}{1\ kilometers }$

In this case $x=85$

Then

$85\ km* \frac{1000\ m}{1\ km} =85,000\ m$

Finally 85 kilometers = 85,000 meters
