Method A: I think is 31 because you first have to get out of the negatives which is already 12, then you have to go to positive 19 which is 19 more, so add those and you get 31.
Method B: The absolute value of the difference between the two numbers is positive 31. This is because the absolute value of -12 is 12 and the absolute value of 19 is 19. Just add.

A ladder reaches 2m up a wall. The foot of ladder is 0.4m from the wall. For safety reasons, the slope should be between 6.3 and

NeTakaya

Answer:

The slope of ladder is not within the safe range .

Step-by-step explanation:

Given as :

The height of the ladder up a wall = h = 2 meters

The distance of base of ladder from the wall = x = 0.4 meters

The estimated safety range of slope of ladder is between 6.3 and 9.5

Let The slope of the ladder = x

<u>According to question</u>

slope of the ladder = $\dfrac{\textrm height of ladder up wall}{\textrm distance of base of ladder from wall}$

Or, x = $\dfrac{2 meters}{0.4 meters}$

Or, x = 5

So, The slope of the ladder = x = 5

Since The estimated range of slope between 6.3 and 9.5

And The calculate slope of ladder = 5

Hence, The slope of ladder is not within the safe range . Answer

What is the 25th term given a₁ = 8 and r = 2?

kondaur [170]

Answer:

134217728

Step-by-step explanation:

The geometric sequence formula is:

$\displaystyle{a_n = a_1r^{n-1}}$

We know that $\displaystyle{a_1=8}$ and $\displaystyle{r=2}$ , we also want to find the 25th term, substitute n = 25:

$\displaystyle{a_{25}=8\cdot 2^{25-1}}\\\\\displaystyle{a_{25}=8\cdot 2^{24}}\\\\\displaystyle{a_{25}=134217728}$

Therefore, the 25th term of sequence is 134217728
