Answer:
y = (1/2) cos (x)
Step-by-step explanation:
It has the same period as cos x but only goes half as high and half as low. Normalyy, cos(x) goes up to 1 and down to -1.
Is john 16?
Since samantha is 48 and she is 2 times older than me, that means im 24 (48/2) and since 3 times older than john that means 48/3= 16. John is 16
Answer:
Yes, he is correct, just divide any number by 4 and you'll get 25% of that number.
Step-by-step explanation:
Answer:
3 quarts
Step-by-step explanation:
4/1 = 12/3 so 12 cups =3 quarts
16)
(4x + 2) is equal to 150 because they are vertical angles. When two lines intersect, on the opposite sides of the x like these are will be equal to one another. So let’s make them equal to each other.
4x + 2 = 150
Subtract 2
4x = 148
Divide by 4
x = 37
So it will be A
17)
The two angles added up with each other
34 + 146 = 180
Since these two add up to 180 degrees, they would be supplementary angles.
So, H
18)
The two angles will make a 90 degree angle (as shown with the little box formed in the corner)
When angles add up to make 90 degrees, they will be complimentary angles.
So, C.
