21 its 21 because it is 21
Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Answer:
B. rotation 90° counterclockwise about the origin.
Step-by-step explanation:
Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.
Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.
In the given question, ∆ABC is mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.
Answer:
Unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. Some common unit rates are miles, per hour, cost per item, earnings and per week
Step-by-step explanation:
Answer:
0.5b + 1.5p ≤ 8
Step-by-step explanation:
The inequality function is as follows:
Let us assume the number of bananas acquired be b
And, the number of peaches acquired be p
Cost of each banana be $0.50
ANd, the cost of each peach be $1.50
Also the total would be $8
The possible values of banana is 0.5b
And, for peaches it would be 1.5p
So, the inequality function is
0.5b + 1.5p ≤ 8
