Wow thx. I just started trig as a freshman and I couldn’t understand it at all. I’ll be sure to save this lol
Answer:
w + w + L + L= 84 or 2w + 2L= 84
Step-by-step explanation:
Answer:
The answers are that x = 8 and y = 7%
Step-by-step explanation:
To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).
1.36/17% = 8
And now to find y, we divide 1.05 by 15
1.05/15 = 7%
Factors of -12 that have a sum of +1 are: -3 and 4.
Answer:
Axis of symmetry: ![x=\frac{5}{6}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5%7D%7B6%7D)
Vertex: ![(\frac{5}{6} ,\frac{73}{12} )](https://tex.z-dn.net/?f=%28%5Cfrac%7B5%7D%7B6%7D%20%2C%5Cfrac%7B73%7D%7B12%7D%20%29)
Step-by-step explanation:
Recall that the formula for the axis of symmetry of a quadratic function of the form:
is that of a vertical line of the form ![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
Since for our case,
then the equation for the axis of symmetry is:
![x=-\frac{5}{2(-3)} \\x=\frac{5}{6}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B5%7D%7B2%28-3%29%7D%20%5C%5Cx%3D%5Cfrac%7B5%7D%7B6%7D)
The horizontal (x) coordinate for the vertex is therefore 5/6, and the y coordinate can be obtained by replacing 'x" with the value "5/6" in the function's expression:
![y=-3x^2+5x+4\\y=-3(\frac{5}{6} )^2+5(\frac{5}{6} )+4\\y=-\frac{25}{12} +\frac{25}{6} +4\\y=-\frac{25}{12} +\frac{50}{12} +\frac{48}{12} \\y=\frac{73}{12}](https://tex.z-dn.net/?f=y%3D-3x%5E2%2B5x%2B4%5C%5Cy%3D-3%28%5Cfrac%7B5%7D%7B6%7D%20%29%5E2%2B5%28%5Cfrac%7B5%7D%7B6%7D%20%29%2B4%5C%5Cy%3D-%5Cfrac%7B25%7D%7B12%7D%20%2B%5Cfrac%7B25%7D%7B6%7D%20%2B4%5C%5Cy%3D-%5Cfrac%7B25%7D%7B12%7D%20%2B%5Cfrac%7B50%7D%7B12%7D%20%2B%5Cfrac%7B48%7D%7B12%7D%20%5C%5Cy%3D%5Cfrac%7B73%7D%7B12%7D)
