Answer:
5.2
Step-by-step explanation:
To find the height of the plant after 7 weeks, we need to find out the equation of the line of best fit and plug in 7 for x. We already have our y - intercept, which is 1, and we have a point on the x axis for which the y coordinate is an integer, (5, 4). Since we already have the y - intercept of +1 we have y = mx + 1. Since this applies to (5,4) we can plug this in to our equation. This is then 4 = 5m + 1. Subtracting 1 from both sides, we get 3 = 5m. Dividing by 5, we receive m = 3/5. Since now we have our slope, we can plug in 7 and find out our answer. Plugging in 7 we receive, y = 3/5 * 7 + 1, which is equal to y = 4.2 + 1. This means that y = 5.2, so 5.2 is our answer.
Average rate of change = (f(29) - f(15))/(29 - 15) = (87 - 45)/14 = 42/14 = 3m/s^2
I’d say 21 tbh unless the sum is half of the brothers age then it would be 9
You do the brackets first so 3x8 = 24 - 7 = 17
You then do divide so 34/17 = 2
You then do the multiplication so 2x3= 6
Then you have 1-2-6 = - 7
The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction
So the answer is - 7
they are all quadrilateral s
hope this helps ;)
