Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
Answer:
![f(5)=3.5](https://tex.z-dn.net/?f=f%285%29%3D3.5)
Step-by-step explanation:
![f(x)=\frac{3}{2}x-4\\f(5)=\frac{3}{2}(5)-4\\f(5)=7.5-4\\f(5)=3.5](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B3%7D%7B2%7Dx-4%5C%5Cf%285%29%3D%5Cfrac%7B3%7D%7B2%7D%285%29-4%5C%5Cf%285%29%3D7.5-4%5C%5Cf%285%29%3D3.5)
Hope this helped!! Have an amazing day :D
Step 1: calculate the cube roots, convert the decimal into a fraction, and calculate the cube roots again
10 + 3 square root 27/1000 - 5
Step 2: calculate the cube root
10 + 3/10 -5
Step 3: subtract the #’s
5 + 3/10
Step 4: calculate and you get
53/10
Answer: 53/10
Answer: See the answers below.
The first equation that needs to be solve is: 10 = -16t^2 + 18
If you use the quadratic equation, you will get 0.707 seconds.
For the second equation, you need to solve 0 = -16t^2 + 18.
If you use the quadratic equation, you will get 1.061 seconds.
No, the rate of change is not constant because this is a quadratic equation.
