Answer:
![y=2x^2-\frac{4}{3}x-\frac{10}{3}](https://tex.z-dn.net/?f=y%3D2x%5E2-%5Cfrac%7B4%7D%7B3%7Dx-%5Cfrac%7B10%7D%7B3%7D)
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
![y=a(x+1)(x-\frac{5}{3})](https://tex.z-dn.net/?f=y%3Da%28x%2B1%29%28x-%5Cfrac%7B5%7D%7B3%7D%29)
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
![40=a(5+1)(5-\frac{5}{3})](https://tex.z-dn.net/?f=40%3Da%285%2B1%29%285-%5Cfrac%7B5%7D%7B3%7D%29)
![40=a(6)(\frac{10}{3})](https://tex.z-dn.net/?f=40%3Da%286%29%28%5Cfrac%7B10%7D%7B3%7D%29)
![40=20a\\a=2](https://tex.z-dn.net/?f=40%3D20a%5C%5Ca%3D2)
substitute
![y=2(x+1)(x-\frac{5}{3})](https://tex.z-dn.net/?f=y%3D2%28x%2B1%29%28x-%5Cfrac%7B5%7D%7B3%7D%29)
apply distributive property
![y=2(x^2-\frac{5}{3}x+x-\frac{5}{3})\\\\y=2(x^2-\frac{2}{3}x-\frac{5}{3})\\\\y=2x^2-\frac{4}{3}x-\frac{10}{3}](https://tex.z-dn.net/?f=y%3D2%28x%5E2-%5Cfrac%7B5%7D%7B3%7Dx%2Bx-%5Cfrac%7B5%7D%7B3%7D%29%5C%5C%5C%5Cy%3D2%28x%5E2-%5Cfrac%7B2%7D%7B3%7Dx-%5Cfrac%7B5%7D%7B3%7D%29%5C%5C%5C%5Cy%3D2x%5E2-%5Cfrac%7B4%7D%7B3%7Dx-%5Cfrac%7B10%7D%7B3%7D)

Answer: 64%
Step-by-step explanation:
Given the following :
Current price of stock = $50
Probability of increase per day = 40% = 0.4
Probability of decrease = 60% = 0.6
Value of increase = $11
Value of decrease = $13
Probability that stock is greater than $30 in two days :
For stock to be greater than $30 in two days ;
It either increases in both days or increases in a day and falls the other
Hence, probability that stock is greater than $30
P(increase and increase) OR P(increase and decrease) OR P(decrease and increase)
(0.4 × 0.4) + (0.4 × 0.6) + (0.6 × 0.4)
0.16 + 0.24 + 0.24 = 0.64
0.64 × 100 = 64%

Answer:
Error
Step-by-step explanation:
(-94)/5+22/22 Given
-18.8+1 PEMDAS (do -94/5 and 22/2)
-17.8 Add the numbers
After you add the numbers, you take the square root. you will get the answer "Error" because you cannot take the square root of a negative number
