we have the number
![6-\sqrt[]{-40}](https://tex.z-dn.net/?f=6-%5Csqrt%5B%5D%7B-40%7D)
Remember that
i^2=-1
so
substitute
![6-\sqrt[]{(i^2)40}](https://tex.z-dn.net/?f=6-%5Csqrt%5B%5D%7B%28i%5E2%2940%7D)
![6-2i\sqrt[]{10}](https://tex.z-dn.net/?f=6-2i%5Csqrt%5B%5D%7B10%7D)
therefore
the real part is 6
the imaginary part is -2√10
Direct variation is of the form: y=kx (inverse variation is of the form y=k/x)
Assuming that k is positive :)
y increases as x increases and y decreases as x decreases. There is a direct ratio that is described by k. k=y/x.
Answer:
a. This data best fits an exponential model.
b. The regression equation would be: y = 8385(1.12)^x
c. The y-intercept would be the starting value of the account.
d. Yes, the correlation coefficient is 0.9983.
e. If you input 6 into the equation, you will get a value of $16,550.
Step-by-step explanation:
I hope this helps, and I would appreciate the brainiest asap.
Answer:
Step-by-step explanation:
(68+75+74+82+88+x)/6=70
(387+x)/6=70
x= 33
