Answer:
Since ΔABC ~ ΔQRS, we know that:
=> AB/QR = BC/RS
=> 2/n = 6/15
=> n = (2 × 15)/6 = 5
*You can also use AB/QR = AC/ QS to calculate n
Answer:
The vertex of the function is
Step-by-step explanation:
Suppose we have a quadratic equation in the following format:
The vertex of the function is the point , in which
In this problem:
This means that
So
The vertex of the function is
Answer:
6.5 feet
Step-by-step explanation:
Based on the Cosines Law, we have:
If we isolate b (which is our x in this problem), we have
We have
a: 2
c: 5
B: 131 (since it's the complement of the 49 degrees angle: 180 - 49).
So, we plug these numbers in the formula....
We round it up to the tenth of the unit... to get 6.5
Exact form: 107/14
mixed number form: 7 9/14
