Answer:
52: 8-Z
54: 18+X
60: 12.3
64: 2.5
52: 8 subtracted from z, the equation will only be 8-z because we do not know what z is.
54: 18 more than a number, we do not know what the number is so we will name it X, more than is adding, so the equation will look like this, 18+X
60: Since y is 6.7, all you have to do is subtract 19-6.7.
64: Since n is 7.5 just divide 7.5 from 3 and you will get 2.5.
Answer:
7.5 min/ mile
Step-by-step explanation:
Divide the time taken in minutes by the distance in miles
3 hours = 3 × 60 = 180 mins
3 hours 15 min = 180 + 15 = 195 mins
Average time = 
= 7.5 min/ mile
Answer:
B) Maximums: (0, 1), (2π, 1);
Minimum: (π, -3)
To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula.
sq rt(-3^2+1^2)
sq rt(9+1)
sq rt(10) would be the length of the radius in this case.
Then we use the sine cosine and tangent fractions
sin:y/r
cos:x/r
tan:y/x
With the values plugged in the equations are
SIN:1/sqrt(10) Since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10
COS:-3/sqrt(10) Since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10
TAN:1/-3 This one can stay the same.
This would be the measures of SIN, COS, and TAN.
