If you start from the "standard" sine function, i.e.
You can change its graph in four ways:
Amplitude: you can multiply the whole function by a constant to stretch/squeeze it vertically. The transformation looks like
Phase: you can add a constant to the argument translate it horizontally. The transformation looks like
Period: you can multiply the argument by a constant to stretch/squeeze it horizontally. The transformation looks like
Shift: you can add a constant to the whole function to translate it vertically. The transformation looks like
In your case, we're changing the period of the function. If the function is squeezed, so you're squeezing the graph horizontally by a factor of 7/4
Answer:
65.5 feet per second
Step-by-step explanation:
In order to calculate the rate of descent we first need to find the difference in heigh that the hot air balloon descended. We do this by subtracting the initial height from the end height like so...
6,039 - 3,288 = 2,751 ft
Now that we have the difference in height we need to divide this by 42 since that is the amount of time it took for this descent to occur.
2,751 ft / 42s = 65.5 ft/s
Finally we can see that the rate of descent was 65.5 feet per second
Answer:
Angle 1= 147
Angle 2= 33
Step-by-step explanation:
(4a+7) + (a-2) = 180
4a+7+a-2=180
5a+5=180
5a=175
a= 35
plug in 35 for A to find measurements
4(35) +7 = 147
(35) -2= 33
25g = r , i think.
I would give an explanation but you seem in a hurry! Have a good day and good luck!
3/5 * 3/3 = 9/15
4 3/5 = 4 9/15
1/3 * 5/5 = 5/15
2 1/3 = 2 5/15
Subtract = 2 4/15
