I’m not sure but I think it is 13
Answer:
-420
Step-by-step explanation:
let the two consecutive integers be
x and (x + 1)
The product of two consecutive integers is 420
x(x + 1) = 420
Distribute
x² + x = 420
Subtract 420 from both sides
x² + x - 420 = 0
The constant is
-420
Let's explain this by using an example. Let's take the square root of 4.
sqrt(4)
You'd think the answer is 2, and you are correct, but the answer is also -2.
Remember that a square root means that the two numbers must be the same, and multiply back up to 4. In this case, the number is 2.
2•2=4
BUT
-2•-2 ALSO =4
therefore there are two square roots...
2 is a square root
AND
-2 is a square root.
This goes with all positive numbers!
I hope this helps! Best wishes :)
Answer:
3.84 feets
Step-by-step explanation:
Given that:
θ = 88°
Radius, r = 2.5
The length of section of the wire, L ; Length of an arc
L = θ / 360° * 2πr
L = 88/360 * 2*π*2.5
L = (88/360) * 15.707963
L = 3.8397
Length of section of wire = 3.84 feets
7. Continuous. and your other answers are correct for all i know. good luck
