Answer:
B
Step-by-step explanation:
seeing input/ output boxes= function
y is proportional to some constant (k)(constant of proportionality) times x
y=kx
y=0.9(x)

Answer:
sin(x) = cos(90°-x)
Step-by-step explanation:
Looking at the graphs of sin(x) and cos(x), you can see that the peaks of the graph are separated by a value of pi/2. If you convert that value into degrees, then the two graphs are separated by 90°. Another way of thinking is from the unit circle. sin(x) = 1 at 90°, and cos(x)=1 at 0°. The difference is still 90°
Answer:
Step-by-step explanation:
We have to get
from the number that goes IN
to the number that goes OUT
using addition and subtraction.
Note:
To get from a small number to a big number will use addition and
to get from a big number to a small number will use subtraction.
1.
from IN: 11 to OUT: 26
11 + ? = 26
Compare the two numbers by making the difference 26 - 11= 15
11 + 15 = 26
Rule: Add 15
See picture for the rest of the rules.
Answer:
x= 128
Step-by-step explanation:
x and 128 are vertical angles and vertical angles are equal
x= 128
