Answer:
a . 9.66 cm
Step-by-step explanation:
a. rule MDAS
multiple first
4(1)=4
4(√2)=5.66
(4+5.66)=9.66cm
It was 210 cm.
The function she used is h(t) = 210 + 33t. This is a linear function, since it is of the form f(x) = mx+b. In a linear function, we have the slope, m, which tells us how much the height increases per year, and the y-intercept, b, which tells us how tall it was when we began measuring. Our m value would be 33 and our b would be 210, so the original height was 210.
We need to find mean of given integers.
We have -16,39,-10,-16,12,31.
In order to find mean, we need to add all the given inetgers.
Therefore, putting plus sign in between integers.
-16+ 39+ (-10)+(-16)+12+31 .
We will add all positive number 39+12+31 = 82
We will add all negative numbers by negative numbers, -16-10-16 = -42.
Therefore, -16+ 39+ (-10)+(-16)+12+31 = 82 - 42 = 40.
We have given total 6 integers.
So, in order to find the mean, we need to apply following formula
Mean = 
We get,
Mean = 40/6 = 6.66666......
We can round it to 6.67.
Therefore, mean of the given integers = 6.67 (approximately) .

Answer:
y=-4/9x+11/3
Step-by-step explanation:
Reminder: slope intercept form is y=mx+b where m= slope and b=y intercept
Two points are given; (6,1) and (-3,5)
First, find the slope
Reminder: slope is y2-y1/x2-x1
You can plug the numbers given into the equation to get 5-1/-3-6 which equals 4/-9
Now, we can use slope point form which is y-y1=m(x-x1)
Once again, plugging the numbers in (any one of the two points will work) will get
y-1=4/-9(x-6)
Simplifying it will get y=-4/9x+11/3.
