Answer:
1) 3 2) y=73x
Step-by-step explanation:
For number 1):
(y2-y1)/(x2-x1)= (-4-[-1])/(-2-[-1])= (-3)/(-1) = 3
For number 2):
Speed=miles/hour= miles per hour
Speed= 146 miles/2 hours= 73 miles per hour
Answer:
Step-by-step explanation:
8.50*40=340

Using the combination formula, it is found that there are 495 ways to choose a 4-topping sandwich.
The order in which the toppings are chosen is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
4 toppings are chosen from a set of 12, hence the number of ways is given by:

Since you're only given the one vector, I assume you're supposed to find the magnitude of <em>v</em>, or ||<em>v</em>||, using the dot product.
We have
<em>v</em> • <em>v</em> = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5
so that
||<em>v</em>|| = √(<em>v</em> • <em>v</em>) = √(5)
and the answer is C.
