Answer:
B = 13
Step-by-step explanation:
The tangent and cotangent are equal when the angles are complementary.
(3B +35) +(2B -10) = 90
5B = 65
B = 13
___
<em>Check</em>
For B=13, the angles are 3B+35 = 39+35 = 74, and 2B-10 = 26-10 = 16. Both are acute angles.
Answer:
no. of senior citizens=x
no.of other people=7-x
cost=30=k(7-x)+(k/2)x. k is the cost of a ticket
k(7-x+x/2)
k(7-x/2)-30=0
k=60/(14-x)
now do trial and error substitution for (x<7) until u get a whole number for k also (k<30). if you have the skills you can suggest the number yourself
ie x= 2, k=5$
False, if a website is secure it will have a lock either infant of the name or behind.
Ervin sells 13 cars per 3 months so 13/3=4.3 cars per month.
this means that
___month___ ___cars sold___
1 4.3
2 2*4.3
3 3*4.3
: :
n n*4.3
the linear function representing the cars sold per month is f(n)=4.3*n
(Practically, this means that the expected number of cars sold after n months is a whole number close to 4.3*n.)
Answer:
the slope is 4.3 (13/3)
