Answer:
x=7/4
Step-by-step explanation:
13x-17x+7=0
-4x+7=0
-4x+7-7=0-7
-4x=-7
-4x/-4=-7/-4
x=7/4

Answer:
number of taxi accidents = 12235.2 which is approximately approximately 12235 accidents
Explanation:
The equation for the number of accidents is given as:
y = -143.3 x² <span>+1823.3 x + 6820
We are given that:
x = 0 represents 1990
x = 1 represents 1991
Therefore:
x = 8 represents 1998
Now, all we have to do is substitute with the value of x = 8 in the equation of accidents to get the number of taxi accidents in 1998 as follows:
y = </span>-143.3 (8)² +1823.3 (8) + 6820
y = -143.3 (64) + 1823.3 (8) + 6820
y = -9171.2 + 14586.4 + 6820
y = 12235.2
If we are asked to approximate the answer, then it would be approximately 12235 accidents
Hope this helps :)
F(x) = x^4 + 9x^2 = x^2(x^2 + 9) = x^2(x^2 - (-9)) = x^2(x - sqrt(-9))(x + sqrt(-9)) = x^2(x + 3i)(x - 3i)
Answer:
The sum is 
Step-by-step explanation:
we know that
The formula of the sum in a geometric sequence is equal to
![S=a1[\frac{1-r^{n}}{1-r}]](https://tex.z-dn.net/?f=S%3Da1%5B%5Cfrac%7B1-r%5E%7Bn%7D%7D%7B1-r%7D%5D)
where
a1 is the first term
r is the common ratio
n is the number of terms
we have
a1=-11
r=-4
n=8
substitute the values
![S=(-11)[\frac{1-(-4)^{8}}{1-(-4)}]](https://tex.z-dn.net/?f=S%3D%28-11%29%5B%5Cfrac%7B1-%28-4%29%5E%7B8%7D%7D%7B1-%28-4%29%7D%5D)
![S=(-11)[\frac{1-(65.536)}{5}]](https://tex.z-dn.net/?f=S%3D%28-11%29%5B%5Cfrac%7B1-%2865.536%29%7D%7B5%7D%5D)
