50.16 cause it says 5 ten times the value
Answer:
35
Step-by-step explanation:
60 - 25 = 35
(x,y) -> (-x, y) because the triangle was reflected over the y-axis
Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.
But these things will change direction of the inequality:
Don't multiply or divide by a variable (unless you know it is always positive or always negative)
Answer:
5536 calculators
Step-by-step explanation:
We integrate the function dx/dt to obtain the number of new calculators between beginning of the 3rd week and end of week 4. Note that beginning of 3rd week is the same as end of 2nd week. So, 
= 
Let u = t + 12, then 
= 1. So, du = dt. We also change the limits of our integration. So, when t = 2, u = 2 + 12 = 14 and when t = 4, u = 4 + 12 = 16
Then 
= ∫₁₄¹⁶ ![{5000(1 -\frac{100}{u^{2} } )} \, du = 5000[ u + \frac{100}{u} ]](https://tex.z-dn.net/?f=%7B5000%281%20-%5Cfrac%7B100%7D%7Bu%5E%7B2%7D%20%7D%20%29%7D%20%5C%2C%20du%20%3D%205000%5B%20u%20%2B%20%5Cfrac%7B100%7D%7Bu%7D%20%5D)
₁₄¹⁶ = ![5000[16 + \frac{100}{16} - (14 + \frac{100}{14} )] = 5000 [16 - 14 + \frac{100}{16} - \frac{100}{14} ] = 5000 [2 + \frac{100}{16} - \frac{100}{14} ] = 5535.7](https://tex.z-dn.net/?f=5000%5B16%20%2B%20%5Cfrac%7B100%7D%7B16%7D%20-%20%2814%20%2B%20%5Cfrac%7B100%7D%7B14%7D%20%29%5D%20%3D%205000%20%5B16%20-%2014%20%2B%20%5Cfrac%7B100%7D%7B16%7D%20-%20%5Cfrac%7B100%7D%7B14%7D%20%20%5D%20%3D%205000%20%5B2%20%2B%20%5Cfrac%7B100%7D%7B16%7D%20-%20%5Cfrac%7B100%7D%7B14%7D%20%20%5D%20%3D%205535.7)
