The answer is <span>b. y=3x^2-5x+9
</span><span>
The general formula for quadratic function is:
y = ax</span>² + bx + c
Among all choices only b. is correct:
y = ax² + bx + c
y = 3x² - 5x + 9
The dot means to multiply
so 43 x 10025 -50
since BEDMAS is applied,
we would do the multiplication first
43 x 10025 = 431075
and <span>431075 - 50 is 431025
FINAL ANSWER: 431025</span>
we are given
An air-filled rubber ball


we can use formula of the average normal strain in the rubber

now, we can plug values
and we get

51+21+x=107
21+x=86
x=65
