Which of the following expressions are also equal to
? Select all that apply.
A. Cos(x)
B. Cos(x - 459)
C. cos(90° - x)
D. Cos(60° - x)
E. COS(45° - x)
Step-by-step explanation:
I feel there is important information lost in the way you provided the problem statement.
e.g. "... also equal to ?"
equal to what ?
sin x = what ?
so, I can only guess some things.
answer C is definitely correct for any angle up to 180 degrees.
answer A is only correct for an angle of 45 or 225 degrees, where sin(x) and cos(x) are both 1/sqrt(2) or both -1/sqrt(2).
answer B is always wrong (459 degrees is no special number, this is a full circle of 360 degrees and then additional 99 degrees there is no special relationship between sine and cosine for 99 degrees, so sine and cosine cannot have the same value for any x).
answer D is always wrong, as there is always a 30 degree difference between the arguments for sine and cosine, and that can never lead to an equal value.
answer E is also always wrong, as these 45 degrees difference also block equal values.
Belle buys 80 pencils with fuzzy tops. She gives 4 to each of her 16 classmates. The expression for the number of pencils she has left is 80-(4-16). Complete each sentence to identify the parts of the expression.
Answer:

(Quadratic Regressions)
A rocket is shot off from a launcher. The accompanying table represents the height of
the rocket at given times, where x is time, in seconds, and y is height, in feet. Write a
quadratic regression equation for this set of data, rounding all coefficients to the
nearest hundredth. Using this equation, find the height, to the nearest foot, at a time
of 6.4 seconds.
Answer:
y = - 15.57x² + 179.32x + 0.20
510
Step-by-step explanation:
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20
Where, height = y
x = time
Using the model obtained ; the height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20
y = - 15.57(6.4^2) + 179.32(6.4) + 0.20
y = 510.1008
y = 510
The quadratic model obtained using a quadratic regression solver with Coefficient rounded to the nearest hundredth is :
y = - 15.57x² + 179.32x + 0.20height = y
x = time
Using the model obtained;
The height, to the nearest foot, at a time, x = 6.4 seconds.
y = - 15.57x² + 179.32x + 0.20 y = - 15.57(6.4^2) + 179.32(6.4) + 0.20 y = 510.1008 y = 510Thus, the correct answer is 510.

17. Find the volume of the figure below. 3 mm 9.7 mm 7.2 mm
Answer:
70.2
Step-by-step explanation:
The volume of the given figure will be 104.76 mm³. Volume is the product of the area of the length/height.
What is volume?
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
The volume of the given figure is;
Volume=Area×Length
Area=(1/2)×9.7×7.2
Area=34.92 mm²
Volume=Area×Length
Volume=34.92×3
Volume=104.76 mm³
Hence,the volume of the given figure will be 104.76 mm³.

Trapezoid A and trapezoid B as shown on the coordinate grid.
Describe three basic transformations on trapezoid A which show trapezoid B is similar to trapezoid A. In your response, be sure to identify the transformations in the order they would be performed.
Answer:
Step-by-step explanation:
The missing diagram showing the trapezoids is attached in the diagram below.
There are three stages by which trapezoid A must be transformed into trapezoid B.
We can see three fundamental differences as follows:

Answer:
soccer: $50.31hockey: $57.78Step-by-step explanation:
Let s represent the FCI for soccer. The given values tell us ...
s + (s +7.47) = 108.09
2s = 100.62 . . . . . . . . . . subtract 7.47
s = 50.31
s+7.47 = 57.78
The FCI for soccer was $50.31; the FCI for hockey was $57.78.
