Answer:
amplitude = 4
Step-by-step explanation:
the amplitude is the maximum subtract the minimum divided by 2
maximum = 1 and minimum = - 7
amplitude =
=
= 4
Answer:
8x-15y=84
Step-by-step explanation:
Multiply 12 to both sides to get rid of the fractions.
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
Answer:

Step-by-step explanation:
If the length of the square side is a units, then the area of the square is

In your case, the side length is

then the area is

Answer:
C
Step-by-step explanation:
how i figured this out was not by using the table, but you can use the table
i just asked myself what two numbers multiplied together has a product of -12, one number must me negative
the two numbers must also add up to -4, meaning the bigger number had to be negative
the only answer that worked was 2 and -6
