Answer:
5+4x=-11
Step-by-step explanation: First it says "The sum of 5 and four times a number" which going to be 5+4x because 4 time a number so it's going to be 4x. Then the last thing you will need to do is to add in the equal sign which the whole equation going to be 5 + 4x = -11.
<span>Ans : Note that:
sin(x) = sum(n=0 to infinity) [(-1)^n * x^(2n + 1)]/(2n + 1)!.
Then, since the series is alternating, the error in the approximation found by taking the first n terms of the series is no bigger than the n+1'th term. In other words:
E ≤ a_n+1 = x^(2n + 3)/(2n + 3)!.
(Note that a_n does not include (-1)^n, the alternating part)
We need that 1/6 ≤ x^(2n + 3)/(2n + 3)!. Given |x| < 1, n = 2 will be the least integer solution. Thus, we need 2 + 1 = 3 terms.</span>
Answer:
9/2 inches or 4 1/2
Step-by-step explanation: Try to find the unit rate FIRST. Divide 2 on both sides and you will get that ONE INCH = 3/2 miles.
Since you need to know the distance for 3 inches, MULTIPLY both SIDES by 3, and you will get 3 INCHES = 9/2 MILES.
4 is the answer :) I hope you
Answer:C
Step-by-step explanation:
I would say D or C but d is the identity property. And C is the distributive property.
