The temperature of coffee 10 minutes after it was poured (120 F) will help in solving the constant “a”.
<span>120 = 120(2 ^ 10a) + 60 </span>
<span>2 ^ -1 = 2 ^ 10a </span>
<span>a = -1/10 </span>
<span>The temperature of coffee 30 minutes after it was poured is: </span>
<span>F = 120 ( 2 ^ -30/10) + 60 </span>
<span>F = 120 * 1/ 8 + 60 </span>
<span>F = 15 + 60 </span>
<span>F = 75</span>
Answer and Explanation:
The value of 5 in 2,458,973 is less than the value of 5 in 4,538,629. This is because within 2,458,973, the 5 is in the ten-thousands place, its value being 50,000. While in 4,538,629, the 5 is in the hundred-thousands place, its value being 500,000, which is much greater than 50,000.
Value of 5 in 2,458,973 < Value of 5 in 4,538,629

Answer:
y=1/4x+3
Step-by-step explanation:
Slope intercept form is written as (y=mx+b)
<u>To define those variables:</u>
- m is the slope
- b is the y-intercept
We have been given both the slope, and the y intercept, therefore just plug in the numbers into the form:
y=1/4x+3
