Answer:
B. x < -1
Step-by-step explanation:
Hello!
Let's put them in order from greatest to least:
Given our possible inequalities, we need to find the inequality that contains all of these values.
The inequality that works is x < -1, as <u>all values are less than -1.</u>
Therefore, the answer is B. x < -1.
Answer:
it is b
Step-by-step explanation:
1. Observe that the f(t) is change by 4 per time t => there's a acceleration of 4 => f''(t) = 4; Take the derivative of it we can get a velocity function. f'(t) = 4t + c. Since the velocity from 100 to 80 is -20 (average), this means at t = 0, f'(0) = -22 => f'(t) = 4t - 22; Take the derivative again to get the position function: f(t) = 2t^2 - 22t + d, here d = 100 should be trivial. So, the function that models the relationship is f(t) = 2t^2 - 22t + 100.
2. By the compound interest formula:
A = P (1 + r/n)^(nt) , since it's yearly, so n = 1;
results A(t) = 100 (1+0.12)^t.
3. The average rate of change is basically finding the slope, m = y1 - y2 / x1 - x2.
Answer:
The answer is B.
Step-by-step explanation:
Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :
their relative speed is 4 mph. so we put
4 mph = (25 mi)/x => x=25/4.
