Answer:
The slope is 25 and the y-intercept is 100
Step-by-step explanation:
With linear equations (y = mx + b), m<em> </em>is always the slope, which, in this case, is 25. It could also be written as , although it's not necessary here
B is always the y-intercept, which is 100 here
Answer:
{x | x ∈ N and 10 ≤ x ≤ 178} or [10,178]
Step-by-step explanation:
This can be written using interval notation as {x | x ∈ N and 10 ≤ x ≤ 178}. Set notation uses {} for the set, defines the variable as x ∈ N and adds any constraints like 10 ≤ x ≤ 178.
Answer: -8.93
Step-by-step explanation:
Given the function:
N(X) = 90(0.86)^x+ 69
X in the interval [0, 6]
For X = 0
N(0) = 90(0.86)^0 + 69
90 + 69 = 159
For X = 6
N(6) = 90(0.86)^6 + 69
90(0.404567235136) + 69
= 105.41105116224
Therefore, average change of change in temperature ;
(temp 2 - temp 1) / ( time 2 - time)
(105.41105116224 - 159) / (6 - 0)
= - 53.58894883776 / 6
= - 8.93149147296
= - 8.93
160 km - 100%
100%+30%=130%
160*130%:100%=208 (km) - <span>the number sought</span>
