The number of taxi accidents is approximated by y equals negative 143.3 x squared plus 1823.3 x plus 6820 and the number of inju
vagabundo [1.1K]
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 :)

Write a linear factorization of the function.
gregori [183]
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)

what is the sum of an 8-term geometric series if the first term is -11, the last term is 180, 224, and the common ratio is -4​
ExtremeBDS [4]

Answer:

The sum is 144,177

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}]

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)}]

S=(-11)[\frac{1-(65.536)}{5}]

S=144,177
