Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:
Lets expand this in the form , so we have:
We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:
We know a and b, let's find the seconds, x,
Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
It can't fit.
Step-by-step explanation:
If it has a right angle then c^2 = a^2 + b^2 where c = the longest side.
c^2 = 9^2 = 81
a^2 + b^2 = 6^2 + 8^2 = 100
- so It cant have a right angle.
$50 minus $24 equals $26 which means that she spent a total amount of $24 on rides 24 divided by 12 equals 2 which means each ride costs $2
We could represent the equation this way I guess ?
50 - ? = 26
?/12 = ?
Or maybe you could replace the question marks with an x
Rate of change is the slope.
6x - 7y = 21
Convert to slope-intercept form(y = mx + b):
Subtract 6x to both sides:
-7y = -6x + 21
Divide -7 to both sides:
y = 6/7x - 3
Now it's in the form of y = mx + b, where 'm' is the slope. So the slope here is 6/7.
y = 2x - 2
This is already in slope-intercept form, so the slope here is 2.
For function C, take any two points and plug them into the slope equation.
m = y2-y1/x2-x1
(2, 7)
(3, 1)
m = (1 - 7)/(3 - 2)
m = -6/1
m = -6
So the slope of function C is -6.
(1, 2) and (-1, -4)
m = y2-y1/x2-x1
m = (-4 - 2)(/(-1 - 1)
m = -6/-2
m = 3
So function D has the highest rate of change.
