Tcecarenko [31]

Answer:

a. Arithmetic

b. $a_{n} = a_{n-1} + 15$

c. $a_{n} = 15n + 125$

Step-by-step explanation:

A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.

In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is ARITHMETIC ✔️

The recursive formula will be the following: $a_{n} = a_{n-1} + 15$

The explicit formula is the following: $a_{n} = 15n + 125$

Solve the multiplication problem -5/8 times 2/3

wel

Answer:

$\frac{-5}{8}\times \frac{2}{3}=\frac{-5}{12}$ or -0.42

Step-by-step explanation:

Given:

The statement says -5/8 times 2/3

Solution:

$=\frac{-5}{8}\times \frac{2}{3}$

$=\frac{-5\times 2}{8\times 3}$

$=\frac{-10}{24}$

the numerator and denominator is divided by 2

$=\frac{-5}{12}$

Therefore, The multiplication of $\frac{-5}{8}$ and $\frac{2}{3}$ is $\frac{-5}{12}$ or -0.42

Answer:

d=100

Step-by-step explanation:

.99d=10 + .89d

subtract .89d from both sides

.1d=10

divide by .1 on both sides

d=100

to check plug in 100 in place of d

Why is it necessary to use the absolute value of the difference when finding the distance on a number line, but not necessary wh

padilas [110]

Remember that the distance on a number line is given by the formula: $d=|x_{2}-x_{1}|$
where
$d$ is the distance between the points.
$x_{2}$ is the second point in the number line.
$x_{1}$ is the first point in the number line.
Now, suppose we are trying to find the distance between the points -1 and -5; our first point is -1, so $x_{1}=-1$ , and our second point is $-5$ , so $x_{2}=-5$ . Suppose we are going to find the distance between the two point without using absolute value:
$d=x_{2}-x_{1}$
$d=-5-(-1)$
$d=-5+1$
$d=-4$
Look what we have here, a negative distance! Since distances cannot be negative, we must use absolute value to always get postie distances between two point on a umber line:
$d=|x_{2}-x_{1}|$
$d=|-5-(-1)|$
$d=|-5+1|$
$d=|-4|$
$d=4$

Now, the distance between two coordinates on a plane is given by the formula: $d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}$
$where$
$d$ is the distance between the two coordinates
$(x_{1},y_{2})$ are the coordinates of the first point
$(x_{2},y_{2})$ are the coordinates of the second point
Notice that $(x_{2}-x_{1})^2$ and $(y_{2}-y_{1})^2$ are squared, so it doesn't matter if we get a negative distance because a negative number raised to an even power (like 2) is always positive; therefore we don't need absolute value in this case because we won't ever get a negative distance.
