Answer:
b
Step-by-step explanation:
Remove full rotations of
2
π
until the angle is between
0
and
2
π
.
sin
(
5
π
6
)
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
sin
(
π
6
)
The exact value of
sin
(
π
6
)
is
1
2
.
1
2
The result can be shown in multiple forms.
Exact Form:
1
2
Decimal Form:
0.5
You multiply vectors and scalar simply by multiplying each component by that scalar:
Finally, you sum two vectors by summing the correspondent coordinates:
Answer:
round it then divide it by 5
Step-by-step explanation:
Easy question.
So, the slope is -x and the y-intercept is at -4.
y = -x - 4
Use this equation and you will find:
y = -2 - 4
y = -6
Answer: (2, -6)
Answer:
D (3,1)
Step-by-step explanation:
solving simultaneous equations
Arrange equations
2x+y=7
3x-4y=5
make y side cancell by addition by multiplying by 4 and 1 as shown
4{2x+y=7}
1{3x-4y=5}
8x+4y=28
3x-4y=5
11x=33
x=33/11=3
substitute for x=3 in 3x-4y=5
9-4y=5
4=4y
y=1
