Answer:
the you run y=3
Step-by-step explanation:
The y-intercept of the trend line is (0,28). The slope of this line is
28-0
m = --------- = 2
14-0
Thus, the equation of the trend line, in variables K and J, is
K = 2J + 28
Answer:
The value of f is 80.6.
Step-by-step explanation:
We are given the equation and asked to solve for f.
If we are given a fraction with a variable in the numerator, we can multiply both sides of the equation by the denominator to isolate it.
For example, if you look at this equation:
![\displaystyle\frac{a}{26}=17.9](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7Ba%7D%7B26%7D%3D17.9)
We can multiply both sides by 26 to get the a by itself so the equation can be solved.
![\displaystyle26\times\frac{a}{26}=17.9\times26\\\\a = 465.4](https://tex.z-dn.net/?f=%5Cdisplaystyle26%5Ctimes%5Cfrac%7Ba%7D%7B26%7D%3D17.9%5Ctimes26%5C%5C%5C%5Ca%20%3D%20465.4)
Therefore, we can apply this same technique to the equation ![\frac{f}{13}=6.2.](https://tex.z-dn.net/?f=%5Cfrac%7Bf%7D%7B13%7D%3D6.2.)
![\displaystyle\frac{f}{13}=6.2\\\\13\times\frac{f}{13}=6.2\times13\\\\f = 80.6\ \text{or} \ \frac{403}{5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7Bf%7D%7B13%7D%3D6.2%5C%5C%5C%5C13%5Ctimes%5Cfrac%7Bf%7D%7B13%7D%3D6.2%5Ctimes13%5C%5C%5C%5Cf%20%3D%2080.6%5C%20%5Ctext%7Bor%7D%20%5C%20%5Cfrac%7B403%7D%7B5%7D)
Therefore, the value of f is 80.6.
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>Quadratic function </u>
with the roots:
<h3>To find </h3>
<h3>Solution</h3>
<u>As we know the sum of the roots is -b/a and the product of the roots is c/a. Substituting values and solving for b and c:</u>
- (-5 + 9i) + (-5 - 9i) = -b/-1
- -10 = b
- b = -10
And
- (-5 + 9i)(-5 - 9i) = c/-1
- (-5)² - (9i)² = -c
- 25 - 81(-1) = -c
- - c = 25 + 81
- - c = 106
- c = -106
g(x) = -x² -10x - 106
In order for this to be solved we need to know the angle of each side. This question cannot be solved unless you show us the Diagram. I'll be happy to help once that is settled<span />
