This is very easy just alot of terrible numbers lol.
If she goes "down" for 90 SEC that means she is moving Negative.
So she moves for 90 seconds at a Rate of 3.5 Feet per second
Which means every second she goes down she will subtract 3.5 Ft
Since she is moving for 90 SEC then this will be the equation
Feet will be negative because she is going down.
-3.5 X 90=? You might need a calculator.
Now that she has gone down she decided to go up. For 30 seconds at a different rate. 2.2 Seconds. So now since she is going up it is Increasing.
Feet will be Positive because she is going up now.
This is the equation
2.2 X 30=?
First you want to add both the equations you solved so far.
Now she wants to go to Exactly 0 . So she decides to go up really fast!
So when you get the amount. She wants to Increase by 4.8 FT Per SEC
So you take the amount you added which should be negative
And put it into an equation.
4.8 Divided by ( the equation you added) = ? SEC
SEC= SECONDS FT= FEET
Answer:
f(x) = -2x +9
Step-by-step explanation:
We can use the slope intercept form
y= mx +b where m is the slope and b is the y intercept
y = -2x +9
Replacing y with f(x)
f(x) = -2x +9
Answer:
The answer is one solution because the graphs are together in one specific point.
Step-by-step explanation:
You use the I = PRN formula
P = 11 500
R = 7.25% but you have to 7.25 divide by 100 so it becomes a decimal so it should be 0.0725
N = 2 years and 6 months. This can be 2.5 years because half of 12 is 6
the solution is 11 500 × 0.0725 × 2.5 = 2084.38
The answer are below, the work is show step by step.
