Right triangle 30 60 90
short leg = 1/2 hypo = 4√2 / 2 = 2√2
so x = 2√2
long leg = short leg times √3 = 2√2 * √3 = 2√6
so y = 2√6
answer C.
x = 2√2 ; y = 2√6
Hello there! The cost of the item is $40, which makes up 100% of the price. There is 8% tax applied on the item. Let's add both percentages. 100 + 8 is 108. That's 108%. Let's multiply that by 40 to get the total price. 40 * 108% (1.08) is 43.2. There. The final cost of an item is $43.20.
Answer:
Step-by-step explanation:
7/12-2/5
We will find the LCM of it to make the denominators same.
Which is 60
Now to make denominators same
7/12×5/5
= 35/60
2/5×12/12
= 24/60
Now using these like values
35/60-24/60
= 11/60
The fraction is already in lowest terms

Answer: Last option.
Step-by-step explanation:
For this exercise you need to find the Discriminant.
The formula used to find the Discriminant, is the following:
In this case, given the Quadratic equation:
You can identify that:
Knowing those values, you must substitute them into the formula and then you must evaluate in order to find the Discriminant.
You get that this is:
By definition, if:
Then the Quadraitc equation has 2 nonreal solutions.
