660 feet
given distance varies directly with time (t) then
d = kt ( k is the constant of variation )
find k using the condition d = 264 when t = 0.5
k = 
= 
= 528
thus d = 528t
when t = 1.25
d = 528 × 1.25 = 660 feet
Answer:
1 and -5
Step-by-step explanation:
0 divided by anything is 0
the numerator can equal zero if one factor =0
so
x-1=0
or
x+5=0
solving, we get x=1 or x=-5

6 9
Answer:
a) It's a quadratic
b) f(x) = A(x-3)(x-7)
c) she is right
Step-by-step explanation:
(0-12)/(3-1) = -6
(-4-0)/(5-3) = -2
Since the slope is not constant, it can't be a linear.
Therefore a quadratic
Since the zeroes are 3 and 7,
Factors are (x - 3) and (x - 7)
f(x) = A(x - 3)(x - 7)
Use any one point besides the x-intercepts to find A
12 = A(1-3)(1-7)
12 = 12A
A = 1
f(x) = (x - 7)(x - 3)
f(x) = x² - 7x - 3x + 21
f(x) = x² - 10x + 21
She is right
Answer:
the answer for the first is the second one
and the answer for the second is 9>6
Step-by-step explanation:
9 is greater than (>) six
and when plotted you can see that 9 is to the right of -6
hope i helped!
