Answer:
k=9
Step-by-step explanation:
![slope = \frac{y2 - y1 }{x2 - x1} \\ \frac{ - 5}{2} = \frac{ - 11 - k}{6 - ( - 2)} \\ - ( \frac{5}{2} ) = - ( \frac{11 + k}{8} ) \\ \frac{5}{2} = \frac{11 + k}{8} \\ 5 \times 8 = 2(11 + k) \\ 40 = 22 + 2k \\ k = \frac{40 - 22}{2} \\ k = 9](https://tex.z-dn.net/?f=slope%20%3D%20%20%5Cfrac%7By2%20-%20y1%20%7D%7Bx2%20-%20x1%7D%20%20%5C%5C%20%20%5Cfrac%7B%20-%205%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B%20-%2011%20-%20k%7D%7B6%20-%20%28%20-%202%29%7D%20%20%5C%5C%20%20-%20%20%28%20%5Cfrac%7B5%7D%7B2%7D%20%29%20%3D%20%20-%20%28%20%5Cfrac%7B11%20%2B%20k%7D%7B8%7D%20%29%20%5C%5C%20%20%5Cfrac%7B5%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B11%20%2B%20k%7D%7B8%7D%20%20%5C%5C%205%20%20%5Ctimes%208%20%3D%202%2811%20%2B%20k%29%20%5C%5C%2040%20%3D%2022%20%2B%202k%20%5C%5C%20k%20%3D%20%20%5Cfrac%7B40%20-%2022%7D%7B2%7D%20%20%5C%5C%20k%20%3D%209)
Yvette wants to earn a profit of $360, then. That means she has to make a total of $480. 480 divided by 18 is 26 and 2/3. That basically rounds up to $26.67.
480 = 18x
360 = 18x - 120
120(3) = 18x - 120
(I'm not that good at this, so don't take my word for it)
Answer:
6.41
Step-by-step explanation:
if u subtract 6.38 from 6.41 you have .03 left over.
Answer:
(a) 0.4
(b) a = 3
Step-by-step explanation:
(a) The area under the curve from x=4 to x=6 is 0.2 units high and 2 units wide, so is 0.2·2 = 0.4. (The area of a rectangle is the product of length and width.)
(b) The area is 0.2 and the height of the curve is 0.2, so the width of the region of concern is 0.2/0.2 = 1. (Again, area = height·width, or width = area/height.) 1 unit from the left end is found at X=3, so a = 3.
By scientific notation I am assuming you mean standard form, as that is used primarily in scientific calculations. The answer in standard form would be
![4.954 \times {10}^{ - 7}](https://tex.z-dn.net/?f=4.954%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%207%7D%20)
I hope this helps!
