Answer:
y=27.8
Step-by-step explanation:
- 8^2=17^2+16^2-2(16)(17)cosY
- 8^2-17^2-16^2/-2(17)(16)=cosY
- -481/-544=cosY
- 0.8842=cosY
- Y is about 27.8
 
        
             
        
        
        
Answer:
C. 66 square units
Step-by-step explanation:
The area of the middle rectangle would by base × height, or y × h, or 6 × 6. 
The area is 36.
The area for one triangle would 1/2 × base × height. 
(But since there are two triangles to solve for, the 1/2 is not necessary, and we can just do base × height again.)
 So, it would be x × h, or 5 × 6.
The area is 30.
Combine both areas to get the whole area of 66 units²
 
        
             
        
        
        
Answer: f(2) = 6
Step-by-step explanation: In this problem, we are given the function
f (x) = (x + 1) 2 and we are asked to find f(2). In other words, if we put an "x" into our function, we get a (x + 1) 2 out.
 f we put a 2 into the function, we get f(2) =  (2 + 1) 2 out. Now all we have to do is simplify on the right side.
 2 + 1 gives us 3 and if we multiply 3 by 2, we get a product of 6.
Therefore, f(2) is 6.
 
        
             
        
        
        
Answer:
The initial value in the word problem is the output value when input value is set to zero.
Step-by-step explanation:
- In the question, it is given that a problem uses a linear function.
- It is required to explain how to interpret the initial value in a word problem.
- In order to find the initial value in a world problem, find the output value when input value is set to zero.
- If the initial value is marked as b for a linear function f(x), find it as follow,
