Answer:
n = (1/9)u
Step-by-step explanation:
This is a direct variation relationship of the form
n = ku
For n = 2, u = 18.
2 = k * 18
We solve for k.
k = 2/18
k = 1/9
Now we use k in the equation of the relationship.
n = (1/9)u

Answer:
sec A = 5/4
Step-by-step explanation:
Sec of an angle is hypotenuse/adjacent side
In your problem, sec A = 25/20 = 5/4
It helps if you can draw a figure of the problem. Make sure you memorize the definition of each trig function
Answer:
If you expand that, it comes out to 200000000, or in scientific notation, 2.0 × 10⁸.
Step-by-step explanation:
Starting with:
(7 × 10⁵) × (3 × 10²)
Since everything is multiplied, we can drop the brackets:
= 7 × 10⁵ × 3 × 10²
Now we can multiply seven by three, and both powers of ten:
= 20 × 10⁷
We can expand this now as
200000000
or in proper scientific notation:
2.0 × 10⁸
