Answer:
11: A 12: B
Step-by-step explanation:
-29 <-21 and a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
We are given:
u+v
t=---------- and are to solve for u.
2
First, multiply both sides by 2; this will eliminate fractions:
2t = u + v. We want to solve this for u.
Subtracting v from both sides, we get 2t - v = u. Thus, u = 2t - v (answer)
The answers would be 1 and 5.
Answer:
892 ft (3 sf)
Step-by-step explanation:
Sin(48) = x/1200
x = 891.7737906 ft
Remember that the quadratic formula is: 
.
stands for the coefficient of the first term, the one associated with the 
, 
stands for the coefficient of the second term, the one associated with 
, and 
stands for the value of the constant.
In 
, our a-value is 1, our b-value is also 1, and our c-value is also 1.
Thus, when we plug in our values into our formula, we get the answer:
Simplifying this answer using 
, we get our final answer of:
