Which student correctly translated the phrase ""twice the sum of a number cubed and nine"" and evaluated it for r = 3? Antonio's work. 2 (r cubed 9) = 2 (3 cubed 9) = 2 (9 9) = 2 (18) = 36. Jessica's work. 2 (r cubed 9) = 2 (3 cubed 9) = 2 (27 9) = 2 (36) = 72. Maria's work. 2 r cubed 9 = 2 3 cubed 9 = 2 27 9 = 29 9 = 38. Mark's work. 2 3 r 9 = 2 3 (3) 9 = 2 9 9 = 11 9 = 20.

The parabola y=x^2 is shifted down by 6 units and to the right by 5 units. What is the equation of the new parabola
Answer:
y = (x - 5)^2 - 6
Step-by-step explanation:
If you slide a parabola up or down, that translation will show up in the equation just tacked on to the end of the equation. Down 6 will be a MINUS 6.
A horizontal shift will show up in the equation tucked in close to the x in a set of parenthesis. BUT it will look less intuitive...a right shift will be a MINUS.
Untransformed:
y = x^2
Shift down 6:
y = x^2 - 6
Shift right 5:
y = (x - 5)^2
Down6 AND Right5:
y = (x - 5)^2 - 6
The diameter of a circle is 22 millimeters. What is the circle's area?
Use 3.14 for PI
please answer i will give brainliest
Solution:
We know that:
Radius: Diameter/2Area of circle: (π)(r²)Step-1: Find the radius:
Diameter = 22 mm=> Radius: 22 mm/2=> Radius: 11 mmStep-2: Find the area of the circle:
Area of circle = (π)(r²)=> Area of circle = (3.14)(11²)=> Area of circle = (3.14)(121)=> Area of circle = 3.14 x 121 = 379.94 mm²[tex]\\ \rm\Rrightarrow Area=\pi r^2[/tex]

State the period, midline, amplitude, and range of the given graph. (I will mark brainliest, my answers were wrong!)
Answer:
Period: [tex]4\pi[/tex]
Midline: y = 2
Amplitude: 3
Range: [-1, 5]
Step-by-step explanation:
Period - from one peak to the next (or from one trough to the next)
⇒ Period: [tex]2\pi - (-2\pi )=4\pi[/tex]
Midline - center line
Range = -1 ≤ f(x) ≤ 5
[tex]\implies \sf midline =\dfrac{5-(-1)}{2}+(-1)=2[/tex]
⇒ Midline: y = 2
Amplitude - height from the center line to the peak (or to the trough)
Maximum height: y = 5
center line: y = 2
Therefore, amplitude = 5 - 2 = 3
Range - the set of all values that the function takes
-1 ≤ f(x) ≤ 5 → [-1, 5]
Period:-
Only one peak is shown so we take distance between troughs

Answer:
y = x/2 means that it's whatever x is and that divided by 2
Step-by-step explanation:
For example for 8 it would be y=8/2 which is 4
14 would be 7
3 would be y= 3 x 2 your multiplying because the value is y so it's 6
Answers (from top to bottom)
y = 4y = 7x = 6Reasoning:
The rule says if you know what x is, divide by 2 to get y
In the first row, if x = 8, then y = x/2 = 8/2 = 4.
In the second row, x = 14 leads to y = 7 since 14/2 = 7.
The third row has us go in reverse. We multiply the y value by 2 to find x
This is because y = x/2 solves to x = 2y. So if y = 3, then x = 2y = 2*3 = 6.
We can then check this to get y = x/2 = 6/2 = 3.

If sine theta almost-equals negative 0.7660, which of the following represents an approximate value of tangent theta, for 180 degrees less-than-theta less-than 270 degrees? 0.7660 0.8392 1.1916 1.4198
The value of the tangent when the angle is from 180 to 270 is 0.9392. Then the correct option is B.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
If sine Θ almost equals negative 0.7660.
Then the angle will be
[tex]\theta = sin ^{-1} (-0.7660)\\\\\theta = -49.996^o[/tex]
The interval of the angle is from 180 degrees to 270 degrees. Then we have to add 270 degrees in the angle. Then the angle will be
[tex]\theta = -49.996^o + 270^o\\\\\theta = 220.0039^o[/tex]
Then the tangent of Θ will be given as
[tex]tan \theta = tan \ (220.0039^o) = 0.8392[/tex]
