There are 14 girls in class five.
<h3>How many of the students are girls?</h3>
28 students were present in class five, such that 18 of them were boys.
The number of girls on Sunday is given by the difference:
28 - 18 = 10
And we know that 4 girls did not go to school on that day, so the total number of girls on class five is:
10 + 4 = 14

Answer:
5 miles
Step-by-step explanation:
If there is 2 people and it costs 12 dollars you will first subtract 2 dolars for each person leaving you with 10 dollars. After that you will divide 10 by 2 for the miles because each mile costs 2 bucks. that will get you to 5 miles
Answer: 2sin^2x+sin2x+cos2x=0 ..... (1).
By using the trigonometric identities below :
sin2x=2sinxcosx
cos2x=cos^2x-sin^2x
We substitute the trigonometric identities into (1).
2sin^2x+2sinxcosx+cos^2x-sin^2x=0
By combining like terms .
sin^2x+2sinxcosx+cos^2x=0.....(2)
The equation (2) is equivalent to the following expression (3).
(sinx+cosx)(sinx+cosx)=0 .....(3).
sinx+cosx=0
cosx=-sinx
divide both sides by cosx
1=-sinx/cosx
-1=sinx/cosx
sinx/cosx=tanx
substitute
-1=tanx
tanx=-1
tangent is negative in 2nd and 4th quadrants
tan135º=-1 (one answer)
tan315º=-1 (second answer)
Step-by-step explanation:
Please refer to the trigonometric identities used and explained above .
