$45.50 ÷ 26% = $175
Total sales for the day is $175.
Answer:
A) 10.38hours
B) 617.95 is the concerntration of CO
Step-by-step explanation:
A) when x=600
T= 0.0002x^2 - 0.316x + 127.9
T= 0.0002(600)^2 -0.316(600) + 127.9
T= 10.38secs
B) to find the concerntration, use Almighty formular
X=-b+-sqrt(b^2-4ac)/2a
0.0002x^2-0.316x-127.9=9
0.0002x^2 - 0.316x + 118.9=0
X= 0.316 +- sqrt(0.316^2) -4(0.0002×118.9)/(2×0.0002)
X= 0.316+(0.68817/0.0004)=962.05 or
X=-0.316 -0.68817/0.0004 =617.95
Therefore X is within the domain of 617.95 is the concerntration
The magnitude of a vector has to do with the vector length that is used to show the initial and final position of the vector.
<h3>What is a Vector?</h3>
This refers to the quantity that has a magnitude and direction and can be used to show position.
Hence, we can see that the vector, magnitude, and the directional angle values are not given so a general overview was given.

Answer:
There is no image
Step-by-step explanation:
Try isolating the variable in the equation
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
