4) The answer is D, 20-35
5) The answer is B
Answer:
A. y = cos x
Step-by-step explanation:
The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.
Step-by-step explanation:
Answer:
the third one, CDE = ZED or DEC= EDZ
Step-by-step explanation:
you need one more angle for AAS and either of those would work.
Answer:
189 = W
Step-by-step explanation:
-21 = -w/9
-21 * 9 = -w/9 * 9
The denominator and numerator in the right side cancel out.
-189 = -w
189 = w
Answer:
((X_2 - X_1)/4, (Y_2 - Y_1)/4)
Step-by-step explanation:
C = The new point
X_1 = The x coordinate of A
X_2 = The x coordinate of B
X_3 = The x coordinate of C
Y_1 = The y coordinate of A
Y_2 = The y coordinate of B
Y_3 = The y coordinate of C
The distance between A and the new point, C, is equal to 1/4 the distance from the X coordinate of A to the X coordinate of b.
So, X_3 = (X_2 - X_1)/4
The Y is the same thing but for the Y coordinate.
Y_3 = (Y_2 - Y_1)/4
This means that the coordinates of C are equal to ((X_2 - X_1)/4, (Y_2 - Y_1)/4)
