Answer:
f(x) = 6x² - 24x + 21
Step-by-step explanation:
The equation of a quadratic function in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (2, - 3 ) , then
f(x) = a(x - 2)² - 3
To find a substitute (1, 3 ) into the equation
3 = 1(1 - 2)² - 3
3 = a(- 1)² - 3
3 = a - 3 ( add 3 to both sides )
6 = a
f(x) = 6(x - 2)² - 3 ← in vertex form
= 6(x² - 4x + 4) - 3
= 6x² - 24x + 24 - 3
f(x) = 6x² - 24x + 21 ← in standard form
3 ones = 3
7 hundredths = 7/100
So equivalent fraction is 3 7/100 or 307/100.
Equivalent decimal is: 3.07
Top left and bottom right yes the rest no
Answer:
from the given info
you can know that there were 16 red ones. (2/3)*24
and 8 green apples
and her classmates ate 3/4 of red ones i.e.
(3/4)*16
=12
and 1/2od green
i.e.
(1/2)*8
=4
and now the total eaten apples
= 12+4
=16
and the remaining number are
24-16
=8
what do u need help w lol
