Answer:
7.8
Step-by-step explanation:
The diameter is the full length across a circle. The radius is always half the diameter. if you divide 15.6 by 2 (to get half), we get 7.8. If this does not answer the question, let me know so I can edit
Given:
Roots:
![\begin{gathered} -3+\sqrt[]{6} \\ -3-\sqrt[]{6} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20-3%2B%5Csqrt%5B%5D%7B6%7D%20%5C%5C%20-3-%5Csqrt%5B%5D%7B6%7D%20%5Cend%7Bgathered%7D)
Point: (-1,4)
To determine the equation of the parabola with the given roots and point, we find the missing values first.
Since the roots are given, we can say that the equation is:
![y=a(x+3-\sqrt[]{6})(x+3+\sqrt[]{6})](https://tex.z-dn.net/?f=y%3Da%28x%2B3-%5Csqrt%5B%5D%7B6%7D%29%28x%2B3%2B%5Csqrt%5B%5D%7B6%7D%29)
Next, we expand the terms.

Then, we plug in x= -1, and y=4 into the equation to get the value of a.

So,
64 hours per hour average
350 miles ÷5.25 hours in which it took= 63.63 rounded is 64 mph average
Answer:
- An <em>independent</em> variable can be assigned any value. The variable that changes depending on the <em>independent</em> variable is called the <em>dependent</em> variable.
- If x is the independent variable, then <em>y</em> would be considered the dependent variable and will change depending on the value of <em>x</em>.
Step-by-step explanation:
The key word is "depending". The <em>dependent</em> variable changes depending on the <em>independent</em> variable.
Answer: 61
<u>Step-by-step explanation:</u>
Multiplying the two largest numbers will produce the greatest value, then add the smaller number.
8 × 7 + 5
Use order of operations (multiply first, then add):
56 + 5
= 61
