Answer:
(7√6)/2
Step-by-step explanation:
The side ratios in these special triangles are ...
30°-60°-90° triangle: 1 : √3 : 2
45°-45°-90° triangle: 1 : 1 : √2
This tells you the length of the horizontal line is 7√3, and the value of x is ...
(7√3)/√2 = (7√6)/2
_____
<em>Additional comment</em>
Call the length of the horizontal line "y". Then the given ratios tell you ...
7 : y = 1 : √3 ⇒ y/7 = √3/1 ⇒ y = 7√3
and
x : y = 1 : √2 ⇒ x/y = 1/√2 ⇒ x = y/√2
When we rationalize the denominator, we get ...
x = (y√2)/2 = ((7√3)√2)/2 = (7√6)/2
Answer:dy/dx=3x^2 + 2
Step-by-step explanation:
y=x^3 + 2x - 1
dy/dx=3x^2 + 2
80% decrease. because 1% of 300 is 3 which you multiply 3*20 and which means 20 percent equals $60 the leftover percent is the decrease
Answer:
29, 19, 11, 77, 37, 23. I made prime number from given digit.
I hope you got it .
The x is a value you have 2 hours m for minutes and your x what u do is draw the shape write the numbers beside the shape and find the area look at the pic for a example.
