Answer:

Step-by-step explanation:
Mr.Mole's digging can be described by a linear model of general equation:

Where "m" is the rate at which he descends. Note that since the function A(t) measure his altitude relative to the ground, the rate "m" must be negative.


The constant "c" is his starting position. To find this value, assign the given data at t = 5 min to the equation above

Therefore, the function A(t) is described by the following formula:

Answer:
n = s/180 +2
Step-by-step explanation:
180(n-2)=s
Distribute
180n - 360 =s
Add 360 to each side
180n -360+360 = s+360
180n = s+360
Divide each side by 180
180n/180 = s/180 + 360/180
n = s/180 +2
Answer:
B 34
Step-by-step explanation:
The arc is 1/2 the same measure of the angle.
<y = 1/2 arc xz
<y = 1/2 (68)
<y = 34
Answer:
huh? I don't understand but if it is 3+1= 4
Step-by-step explanation:
12 is the answer because you subtract 8 from 20
