Refrection of a function across the y-axis, changes the sign of x in the function.
Thus, given the function:
Refrection of the function across the y-axis will result in the function:
Refrecting a function across the x-axis, changes the sign of the function.
Thus, refrecting the function:
across the x-axis will result in the function:
The graph of
and
is attached.
The green curve represents the graph of the function
, while the orange curve represents the graph of the function
.
They are inversely proportional hence v=s/t
The long way to compute the sum is to expand each number completely, then add:
3.61 * 10^5 = 3.61 * 100,000 = 361,000
6.05 * 10^6 = 6.05 * 1,000,000 = 6,050,000
Then
3.61 * 10^5 + 6.05 * 10^6 = 6,411,000 = 6.411 * 10^6
A shorter way would be to expand the larger of the two numbers until the powers of 10 match up, then add:
6.05 * 10^6 = 60.5 * 10^5
Then
3.61 * 10^5 + 60.5 * 10^5 = (3.61 + 60.5) * 10^5 = 64.11 * 10^5 = 6.411 * 10^6
Answer:
y = 40x
Step-by-step explanation:
Given - Alex walks from her home to the bus stop at a rate of 40 steps per minute.
To find - Write a rule they gives her from home in steps as a function of time after she leaves her home.
Proof -
The function will be a linear function.
The linear function is in the format of y(x) = mx + c
Let x be the total minutes
y be the total steps
So, the rule becomes
y(x) = 40x + 0
⇒y = 40x
As she walks 40 steps in 1 minutes
So, rate of change will be 40 and constant term will be 0.
