Given:
(3,6) and (4,10)
a) f(x) = 4x - 6
f(3) = 4(3) - 6 f(4) = 4(4) - 6
f(3) = 12 - 6 f(4) = 16 - 6
f(3) = 6 f(4) = 10
b) f(x) = x + 4
f(3) = 3 + 4 f(4) = 4 + 4
f(3) = 7 f(4) = 8
c) y = x + 4
y = 3 + 4 y = 4 + 4
y = 7 y = 8
d) y = 4x - 6
y = 4(3) - 6 y = 4(4) - 6
y = 12 - 6 y = 16 - 6
y = 6 y = 10
Among the choices, choice A and D have the same value. However, the problem says functions notation. Choice A. is the function notation. A.) f(x) = 4x - 6
Answer:
(2, 1).
Step-by-step explanation:
x^2 - 4x + 5 = 0
(x - 2)^2 - 4 + 5 = 0
(x - 2)^2 + 1 = 0
The vertex is at (2, 1).

The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
- The scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).
Step-by-step explanation:
You can observe in the figure attached that "AC" is the distance between the Sun and the shooting star.
Knowing the distance between the Earth and the Sun "y" and the angle x°, the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.
This is:
cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
In this case:
\begin{gathered}\alpha=x\°\\\\adjacent=BC=y\\\\hypotenuse=AC\end{gathered}
α=x\°
adjacent=BC=y
hypotenuse=AC
Therefore, the scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=
hypotenuse
adjacent
, and solve for the distance between the Sun and the shooting star "AC":
cos(x\°)=\frac{y}{AC}cos(x\°)=
AC
y
AC=\frac{y}{cos(x\°)}AC=
cos(x\°)
y
For most questions asking for the area of a part of a figure, you first have to find the area of the figure then divide to get the part. Because the water level is 2/3 up, we can divide by 3 and that would make it the needed 1/3.
Volume of a rectangular prism: L*W*H
3 3/4 * 3 3/8 * 13 1/3
Becomes
168 3/4
Then divide by 3
56 1/4
or
56.25
