Answer: c 17.9°
Step-by-step explanation:
Answer:
the answer is c
Step-by-step explanation:
I took the test
y=3cos pi x
y=2 sin 3x
y=-4 sin 2x
Answer:
Option 2. y = 3 cos πx is the answer.
Step-by-step explanation:
If the function is in the standard form of y = acos(bx+c) or y = asin(bx+c)
Then period of the given function will be = 2π/b
1) For y = cos(x - π/2)
Therefore period of the function will be = 2π/1 = 2π
2) For y = 3cos πx
Period = 2π/π = 2
Correct option.
3) y = 2 sin 3x
Period of the function = 2π/3
4). y = -4sin 2x
Period of the function = 2π/2 = π
So option 2 is the answer.
Answer:
2n-7
Step-by-step explanation:
the product of 2 and a number is 2 times a number, so number is n. (this is multiplicaiton) it then becomes 2n. 7 less than that is 2n-7. (If it's less than, it goes after the variables 2n)
Explanation:
7 less --> -7
product of 2 and a number --> 2x
Answer:
2x-7
I hope this Helps!!
Select one:
O a. 1
b. 2
O c. 1 or -2
O d. -1 or 2
Answer:
x=1
Step-by-step explanation:
Steps:
1: Step 1: Subtract 2 from both sides.
4x+2−2=6−2
4x=4
2: Step 2: Divide both sides by 4.
4x4=44x=1
Answer: x=1
Hope this helps.
Answer:
1
Step-by-step explanation:
Given expression:
4x+2=6
Bringing 2 to the other side, it becomes negative..
4x=6-2 = 4
4x=4
again 4 brought to rhs n divided..
x=4/4
x= 1
So the correct option is (a)
