Answer:
week 1 < week 2
The graph in the attached figure
Step-by-step explanation:
we know that
<em>Week 1</em>
The water level is 1.4 cm
<em>Week 2</em>
The water level is 1 1/2 cm
Convert to decimal number
Remember that
![1\frac{1}{2}=1+\frac{1}{2}=1+0.5=1.5\ cm](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D1%2B0.5%3D1.5%5C%20cm)
<em>Week 3</em>
The water level is -2.1 cm
Compare the values of week 1 and week 2
1.4 cm is less than 1.5 cm
so
The symbol is <
1.4 < 1.5
week 1 < week 2
The graph in the attached figure
6*6 =36
14/2 =7
36+7= 43
100-82= 18
43 > 18
therefore A is truw
Answer:
Options B and D.
Step-by-step explanation:
The general form of sine function
![h(x)=A\sin (Bx+C)+D](https://tex.z-dn.net/?f=h%28x%29%3DA%5Csin%20%28Bx%2BC%29%2BD)
where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
The general form of cosine function
![h(x)=A\cos (Bx+C)+D](https://tex.z-dn.net/?f=h%28x%29%3DA%5Ccos%20%28Bx%2BC%29%2BD)
where, |A| is amplitude,
is period,
is phase shift and D is y-intercept.
In function, ![f(x)=-\sin x-1](https://tex.z-dn.net/?f=f%28x%29%3D-%5Csin%20x-1)
Amplitude : ![|A|=1](https://tex.z-dn.net/?f=%7CA%7C%3D1)
y-intercept : -1
In function, ![f(x)=-2\sin x-1](https://tex.z-dn.net/?f=f%28x%29%3D-2%5Csin%20x-1)
Amplitude : ![|A|=2](https://tex.z-dn.net/?f=%7CA%7C%3D2)
y-intercept : -1
In function, ![f(x)=-\cos x](https://tex.z-dn.net/?f=f%28x%29%3D-%5Ccos%20x)
Amplitude : ![|A|=1](https://tex.z-dn.net/?f=%7CA%7C%3D1)
y-intercept : 0
In function, ![f(x)=-2\cos x-1](https://tex.z-dn.net/?f=f%28x%29%3D-2%5Ccos%20x-1)
Amplitude : ![|A|=2](https://tex.z-dn.net/?f=%7CA%7C%3D2)
y-intercept : -1
Therefore, the correct options are B and D.
Answer: it is linear
Step-by-step explanation: A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1
Equation of circle:
(x+2)^2 + (y+8)^2 = 17
Point (-6, -7)
(-6+2)^2 + (-7+8)^2 = 17
(-4)^2 + (1)^2 = 17
16 + 1 = 17
17 = 17
Answer is YES
