  • Yes, it is function
  • x-values are unique and each has one corresponding y-value

#2

  • No, it is not a function
  • x-values are repeated with different y-value: (13, 4) and (13, -4)

#3

  • Yes, it is a function
  • If you put a vertical line, there will always be one intersection with the graph

Find the tangent of both angle A and angle B. Ignore what the picture says the numbers are the same.
Elena-2011 [213]
For the angle A we have:
 tan (A) = C.O / C.A
 tan (A) = 10/24
 Simplifying we have:
 tan (A) = 5/12
 For angle B we have:
 tan (B) = C.O / C.A
 tan (B) = 24/10
 Simplifying we have:
 tan (B) = 12/5
 Answer:
 
The tangent of angles A and B is given by:
 
tan (A) = 5/12
 
tan (B) = 12/5

What is the sum of the first 10 terms in the geometric sequence -3 6 -12 24 -48
vlada-n [284]
Use the formula for the sum of a geometric sequence:
Sum = (a(r^n - 1))/(r - 1)
where a is the first term, -3
r is the common ratio, -2
and n is the number of terms

Thus,
Sum = ((-3)((-2)^10 - 1))/(-2-1) = 1023

The interval​ time, I, in​ minutes, between appointments is related to total number of minutes T that a doctor spends with patie
zmey [24]

Answer:

Approximately 5.19 hours.

Step-by-step explanation:

The question is asking that you solve for T (the amount of time spent with patients in a day). To do so, simply input the values which it has given you for your variables. We can substitute 16 for I as that is the doctor's preferred interval time and we can substitute 21 for N as that is the amount of appointments the doctors wishes to have per day.

16=1.08(\frac{T}{21} )

To solve, start by multiplying both sides by 21.

336=1.08T

Next, divide both sides by 1.08.

311.11=T

Your answer comes out to 311.11 minutes. The question is asking for this to be translated into hours per day, which equates to approximately 5.19 hours.
