As the question is written, the correct answer is:
19519.
Explanation:
Our question states
y = 143.3(5)² + 1823.3(5) + 6820
To evaluate this, we use the order of operations (PEMDAS). There is nothing to be evaluated in parentheses, so P is taken care of.
The E part, exponents, is 5². This is 25, which gives us:
y = 143.3(25) + 1823.3(5) + 6820
Next we have M and D, multiplication and division (in the order they appear). Our multiplication is:
143.3(25) = 3582.5; and
1823.3(5) = 9116.5.
This gives us:
y = 3582.5 + 9116.5 + 6820
Lastly, we add these:
y = 12699 + 6820
y = 19519
There were 12561 taxi accidents occurred in 1997
A quadratic function is a function that has the term x²
The quadratic function forms a parabolic curve
The general formula is
f (x) = ax² + bx + c
where a, b, and c are real numbers and a ≠ 0.

The number of taxi accidents is approximated by y equals negative 143.3 x squared plus 1823.3 x plus 6820 y = −143.3x2 + 1823.3x + 6820 and the number of injuries is approximated by y equals negative 416.72 x squared plus 4416.7 x plus 8500 y = −416.72x2 + 4416.7x + 8500. Let x equals = 0 represent 1990, x equals = 1 represent 1991, and so on.
According to the equation for the number of accidents, if the trend continues, how many taxi accidents occurred in
1997?
If we look at the value of x = 0 for 1990 and x = 1 for 1991, than the value of x = 7 for 1997.
We enter the value x = 7 in the equation:
y = −143.3x² + 1823.3x + 6820
y = −143.3 (7²) +1823.3 (7) +6820
y = -143.3 (49) + 12763.1 + 6820
y = -7021.7 + 19582.4
y = 12561.4, round up to 12561
