Answer:
False
Step-by-step explanation:
cos(x) = adjacent side divided by hypotenuse, not the other way around.
The hypotenuse is always the longest side in a righ triangle, so cos(x) will never be greater than 1.
Answer:
1. y=-5x+5
2. y=3x
3. the slope is 6 and the y-intercept is 7
Step-by-step explanation:
Answer:
Sx = 3 units
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = h
b = 8/2 = 4
c = 5
plugin values into the formula:
h² + 4² = 5²
h² = 5² - 4²
x = √9
x = 3
For this case we have the following polynomial:
Rewriting the exponent term equal to 1 we have:
Then, grouping terms we have:
By doing 3x common factor in the first parenthesis we have:
Then, by making the expression common factor within the parentheses we have:
Answer:
The factors that jenna needs to model for the sides are:
<span>A 5.0 L vessel holds 3.0 mol N2, 2.0 mol F2, and 1.0 mol H2 at 273 K. What is the partial pressure of fluorine?
P = nRT /V
P = 6(0.08206)(273) / 5.0
P = 26.88 atm
x(F2) =2/6 = 0.33
Partial pressure = 8.96 atm = 907 kPa
