Answer:
-16
Step-by-step explanation:
Independent, x-coordinate, input, domain.
Dependent, y-coordinate, output, range.
Domain: {0.5, 1, 4, 6, 8}
Range: {1, 1.5, 10, 12, 18}
The arc length of the circle is 5π/9 units
<h3>How to determine the arc length?</h3>
From the question, we have the following parameters
Angle, ∅ = 5π/9
Radius, r = 1 unit
The arc length (x) is calculated as
x = r∅
Substitute the known values in the above equation
x = 5π/9 * 1
Evaluate the product
x = 5π/9
Hence, the arc length of the circle is 5π/9 units

Answer:
Switch to the other streaming service
Step-by-step explanation:
So, 96$ with a 12% increase is $107.52.
But if you do 8.75×12 you get $105.
So Clare should switch to the other music stream.
Answer:
Step-by-step explanation:
[...] if you can write the LHS as a perfect square, or if you can't spot a factorization of it right away, if and only if the discriminant 
(or, if b is an even number, 1/4 of it) is zero.
<u>I see it! I see it!</u>
Stare at it for a while. First term is 
, third term is 
, we are missing a double product, but we can play with k. For the LHS to be 
you just need 
.
<u>I don't see it...</u>
Then number crunching it is. Set the discriminant to 0, solve for k
