F(x) = x² - 10x + 24
opens up because coefficient of x² is positive
crosses x-axis at x = 6 and x = 4
crosses y-axis at y = 24
vertex is a minimum at (5, -1)
To check if two vectors are orthogonal(perpendicular), simply check their dot product, if their dot product is 0, then they're perpendicular, let's check.

to check if two vectors are parallel, simply check their slope by doing a b/a check, if the slopes are the same, then they're indeed parallel to each other, let's check.

well, there you have it, the slopes are the same.
Answer: A) 15
Step-by-step explanation:
Because of Pythagorean Theorem, 9^2+12^2=BC^2. Thus, 81+144=BC^2. Thus, 225=BC^2. Thus, 15=BC.

- <em>combined mass in scientific notation can be written as</em> 97.2×
kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x
kg )
Mercury= (3.3x
kilograms)
Then we add together
(6.42x
)+ (3.3x
) kilograms.
= 9.45 ×
kilograms
Therefore, combined mass in scientific notation can be written as 97.2×
kg

Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number
