Answer:
18.682
Step-by-step explanation:
Given that :
E = (-7, - 2) ; x1 = - 7 ; y1 = - 2
F = (11, 3) ; x2 = 11 ; y2 = 3
EF = √((x2 - x1)² + (y2 - y1)²)
EF = √((11 - -7)² + (3 - -2)²)
EF = √((11 + 7)² + (3 + 2)²)
EF = √(18² + 5²)
EF = √324 + 25
EF = √349
EF = 18.6815
EF = 18.682 units (3 decimal places )
Answer:
there is no solution
Step-by-step explanation:
y = 2x + 1
put into other equation
2x - 2x + 1 = 3
0x + 1 = 3
0x = 2
0/0x = 2/0
x = undefined

Step-by-step explanation:
if 1 inch equals 2.54 cm then 5ft will be:
=5*2.54
=12.7 cm
therefore, sara's height in centimeter:
=12.7+10
=22.7 cm
ANSWER

EXPLANATION
The frequency of a wave function refers to the number of times the graph repeats its cycle within the interval [0,2π]
We can observe explicitly from the graph that the frequency is half.
The period of the given function is 4π


Hence the frequency is half.
