C. 1/root2

Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.

Answer:

I think the answer is that Best Market sells strawberries at a higher unit price, and that you would have to pay $5.40 more at that store than the other.

Step-by-step explanation:

If we take a look at the graph, we can see that 1 pound of strawberries is worth 2$. That makes the unit price, or the price of per one unit of the item, 2$ for  Fine Foods.

In thd directions, they gave us the equation y = 2.9x for strawberries at Best Market. To find the unit price for Best Market, we would have to substitute x for 1 since x represent pounds, and we're trying to find how much 1 pound costs to find the unit price. It would look like this:

y = 2.9 (1)

y = 2.9

So, the unit price at Best Market would be 2.90$.

Comparing the unit prices, 2.90$ is bigger than &2. So, Best Market sells strawberries at a higher unit price. To find out how much 6 pounds of strawberries at Best Market is, all we have to do is substitute x for 6 in y = 2.9x like so:

y = 2.9 (6)

y = 17.40

So, the price for 6 pounds of strawberries is 17.40$ at Best Market. If we refer to the graph for the cost of 6 pounds at Fine Foods, then we know that 6 pounds of strawberries is 12$. 17.40 - 12 = 5.4. So, you would have to pay $5.40 more for 6 pounds at Best Market than Fine Foods.

Two lines have slopes of 1/2 and 2. Are the lines perpendicular? Explain.
Natali [406]

Answer:

The lines are not perpendicular

Step-by-step explanation:

m1=1/2

m2=2

m1*m2=1/2*2=1

Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular
