Answer:
Step-by-step explanation:
Find the limit of x to 0 of 4•Sec(4x)^-2
We know that, Sec4x = 1 / Sin4x
Then,
Lim x → 0: 4•(1 / Sin4x)^-2
Lim x → 0: 4•(Sin4x)²
Then,
Lim x → 0: 4(Sin(4×0))²
Lim x → 0: 4(Sin0)²
Lim x → 0: 4
Then, the limit as x → 0 is 4.
The correct answer is 4

Answer:
53x - 4 = 30
53x = 30 +4
53x = 34
x= 34/53

Answer:
0.15-0.75p? YES
-0.45-0.6+0.75P? NO
-3(-0.05+0.25p)? YES
-3(0.15)+(-3)(0.2)+(-3)(0.25p)? NO
Step-by-step explanation:
-3(0.15-0.2+0.25p)
=-0.45+0.6-0.75p
=0.15-0.75p
1. 0.15-0.75p=0.15-0.75p? YES
2. -0.45-0.6+0.75P=0.15-0.75p?
-1.05+0.75p=0.15-0.75p? NO
3. -3(-0.05+0.25p)=0.15-0.75p?
0.15-0.75=0.15-0.75p? YES
4. -3(0.15)+(-3)(0.2)+(-3)(0.25p)=0.15-0.75p?
-0.45-0.6-0.75p=0.15-0.75p?
-1.05-0.75p=0.15-0.75p? NO
 
        
             
        
        
        
Since .68 is 68/100, you can simplify to 17/25.
