Answer:
#1 d= 49t
Step-by-step explanation:
#2 Since the greatest value of n is 9, it means that the value of n is less than or equal to 9. But the values of n cannot be greater than 9. So, we will be using the sign of less than or equal to in the inequality. Thus, (D) is the correct option.
#3 is (29)
#4 is n=15
#5 is y = 7x
#6 is y=7x
Correct question:
Evaluate and simplify the expression when a = 3 and b = 2,
given expression = 3b-2(1 - b)a - 2
Answer:
3b-2(1 - b)a - 2 at the given values is 10.
Step-by-step explanation:
Given;
3b-2(1 - b)a - 2
The expression is simplified as;
3b-2(1 - b) a - 2 = 3b - 2a(1 - b) - 2
= 3b - 2a + 2ab - 2
When a = 3 and b = 2; then, substitute these values in the simplified expression above;
3b - 2a + 2ab - 2 = 3(2) - 2(3) + 2(3 x 2) - 2
= 6 - 6 + 12 - 2
= 10
Therefore, 3b-2(1 - b)a - 2 at the given values is 10.
Answer:
If you need to find how deep Lake Michigan is, it is 280 meters below the surface
Step-by-step explanation:
In order to find the concentration after 11 minutes, let's use the value of t = 11 in the function C(t) and then calculate its value:
Rounding to three decimal places, we have a concentration of 0.036.
