Step-by-step explanation:
it just means that the parabola never touches the x axis is all
Answer:
if y is the normal number of sweets then the normal number plus 40 percentage equals 42
y+4y=42
1.4y=42
y=42/1.4=30

Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = ![(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%2C-%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%29)
OP.Cosθ = 1×Cosθ = ![\frac{1}{\sqrt{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D)
Cosθ =
θ =
,
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -![\frac{1}{\sqrt{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D)
Sinθ = -![\frac{1}{\sqrt{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%20%7D)
θ =
,
where n = integer
Common value of θ will be, θ = ![\frac{7\pi }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B7%5Cpi%20%7D%7B4%7D)
Option B will be the answer.
You have 3 whole units and 62 hundreths. So the 3 is a whole number. It stands for 3 whole
