Answer:
Step-by-step explanation:
If I'm not mistaken, the 76 degrees means that a is equal to 76 deg. Just visually, if you were to widen that angle, similarly, a would grow just as much.
If you know that a = 76d, b = 76d as well
Answer:
c 44
Step-by-step explanation:
We presume the temperature is decreasing at midnight, so reaches a low at 6 a.m.. The amplitude of the variation is (87-63)/2 = 12 degrees. We want the period to be 24 hours, so the argument of the sine function will be 2π(t/24) = πt/12. Then we can write
... d = 75-12sin(π·t/12)
P(5 on one throw) = 1/8
expected number of 5's in 400 throws = 1/8 * 400 = 50
You could say:
y = 4x + 10
John runs 10 miles a week, after every month he adds 4 miles.
y = 3x + 15
Mary runs 15 miles a week, after every month she adds 3 miles.
'y' would represent the total miles and 'x' would represent the number of months.
