What the slope between 2,0 and-1,6

icang [17]

Answer: The slope is -2

Step-by-step explanation:

-First, you need the formula in order to find the slope:

$m=\frac{y2-y1}{x2-x1}$

-Place the two points onto the equation:

$m=\frac{6-0}{-1-2}$

-Then, you solve:

$m=\frac{6-0}{-1-2}$

$\frac{6-0}{-1-2}= \frac{6}{-3}=-2$

Result:

$m=-2$

4. What is the rule of the nth term of the geometric sequence with <img src="https://tex.z-dn.net/?f=a_%7B4%7D" id="TexFormula1"

hram777 [196]

Answer:

$\text{d.}\quad a_n=-2.25(2)^{n-1}$

Step-by-step explanation:

The common ratio is given as 2, so the base of any exponential must be 2 (not -2 or 2.25). The 4th term is negative, so the initial value must be negative (since the multiplying factor is positive). The only selection matching these requirements is d.

You know the general term is ...

... an = a1·r^(n-1)

so the 4th term is

... -18 = a1·2^(4-1) = 8·a1

Then the first term is ...

... a1 = -18/8 = -2.25 . . . . . confirms our choice of answer d.

vladimir2022 [97]

Answer:

D. 1/2

Step-by-step explanation:

Coin tosses are independent. Past results don't affect future probabilities. So the probability of getting heads on the fourth toss is still 1/2.
