Answer: t = 3seconds
Step-by-step explanation:
To find the zero means we will equate the function to zero and then solve, that is
+ 32t + 48 = 0
by factorizing , we have
(t+1)(-16t+48) = 0
Therefore:
t = -1 or t = 3
since time can not be negative , then , t = 3 seconds
Answer:
Balance = $124.53 – $57.49 + $103.49 = $170.53
Step-by-step explanation:
-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept
To find "m", you can use the slope formula and plug in the two points:




The slope is 0 so:
y = mx + b
y = 0x + b [any number multiplied by 0 is 0]
y = b
To find "b", you plug in either of the points into the equation (since both of their y values are 1]
y = b
1 = b
Your equation is:
y = 1 (This is a horizontal line)
Y - 9 = -1/4 ( x + 2)
