Answer:
Ralphie's dad can eat 8 fruit bars without going over his calorie allotment.
Step-by-step explanation:
Given,
Per day calorie intake limit = less than 2126 calories
Calories are already taken = 1586 calories
Calories in each fruit bar = 66 calories
Let,
x be the number of fruit bars that Ralphie's dad can consume.
Calories in each fruit bar*Number of fruit bars + calories already taken < per day limit
Dividing both sides by 66
17²-8²=225
√225= 15
therefore both x and y are 15 ft
Answer:
1845 years
Step-by-step explanation:
Decay of Carbon-14 is usually modeled by an exponential function. It x is the number of years since the original amount was brought into existence, then the fraction remaining (y) is modeled by ...
... y = (1/2)^(x/5730)
We want to find the value of x when y = 80% = 0.80. The equation is then ...
... 0.80 = 0.50^(x/5730)
Taking logarithms, we get
... log(0.80) = (x/5730)·log(0.50)
Multiplying by the inverse of the coefficient of x, we have
... x = 5730·log(0.80)/log(0.50) ≈ 1845 . . . . years
