2. Given that tan 25º = a, express each of the following in terms of a.
tan 205
sin 25°
cos 65
cos 245
Answers
9514 1404 393
Answer:
tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)Step-by-step explanation:
The tangent function is periodic with a period of 180°. So ...
tan(205°) = tan(25°) = a
__
The identity relating sine and tangent is ...
sin(x) = tan(x)/√(tan²(x)+1)
Rationalizing the denominator gives ...
sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)
sin(25°) = a√(a²+1)/(a²+1)
__
cos(65°) = sin(25°) = a√(a²+1)/(a²+1)
__
cos(245°) = -sin(25°) = -a√(a²+1)/(a²+1)

Answers
Answer:
C
Step-by-step explanation:
They are complementary which means they add to 90. I take it that the c is a typo and you meant x
6x + 3 + 4x + 7 = 90 Combine like terms.
10x + 10 = 90 Subtract 10 from both sides
10x = 90 - 10
10x = 80 Divide by 20
x = 80/10
x = 8

Answer:
1007
Step-by-step explanation:
Divide the expression by two parts: the first one with all positive integer (the integer which can't be divided by two), 1+3+5+...2013 and the rest -2-4-6-...-2012
If you notice both parts are arithmetical sequences
Explore the first one 1+3+5...+2013
a1=1 d=3-1=2 an=2013
a1+d(n-1)=an
1+2(n-1)=2013
2(n-1)=2012
n-1=1006
n=1007
Sn=( 1/2)*(a1+an)*n= 0.5*2014*1007=1007*1007=1014049
-2+(-4)-...-2012
a1=-2
d=a2-a1= -4-(-2)=-2
a1+d(n-1)=an
-2+(-2)(n-1)=-2012
n=1006
Sn= (a1+an)/2*n=(-2-2012)/2*1006=-1007*1006
-1007*1006+1007*1007= 1007- the answer
The second mean
1-2=-1
3-4=-1
5-6=-1
There are 2012/2=1006 couples and every of them has sum -1

B. 64
C. 77
84
Answers
Answer:
a. 62
Step-by-step explanation:
use the Bodmas method
=3×9-5+20×2
=62
The value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.
How to evaluate a given mathematical expression with variables if values of the variables are known?We can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
So, use the Bodmas method
=[3 × 9 - 5 ]+ 20 × 2
= [27 -5] + 40
= 22 + 40
=62
Therefore, the value of the expression {[3 x (3+6) - 5] + 20 x 2 will be 62. so option A is correct.
