Answer:
Rectangle 1: 84 ft^2 Rectangle 2: 8 ft^2
Step-by-step explanation:
Split the figure into two rectangles
Rectangle 1:
Width of rectangle 1 can be found by subtracting 8 ft from 15 ft
15-8=7 ft (width)
length is already given as 12 ft
So,
A = L x W
A = 12ft x 7 ft
A = 84 ft^2
Length is already given of one of the rectangles
Rectangle 2:
Finding the width of Rectangle 2 can be found by subtracting 11 ft from 12 ft to find the length of that dashed line or the width of rectangle 2.
12 ft - 11 ft = 1ft (width)
Length: 8 ft
Width: 1ft
A=l x w
A=8 x 1
A=8 ft^2

Answer: (47.51, 54.49)
Step-by-step explanation:
Confidence interval for population mean is given by :-
, where n= sample size .
= population standard deviation.
= sample mean
= Two -tailed z-value for
(significance level)
As per given , we have
n= 44
Significance level for 95% confidence =
Using z-value table ,
Two-tailed Critical z-value :
Now, the 95% confidence interval for the true population mean textbook weight will be :-
Hence, the 95% confidence interval for the true population mean textbook weight. : (47.51, 54.49)
Answer:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
Step-by-step explanation:
For this case we have the position function s(t) given by:
And we can calculate the instanteneous velocity with the first derivate respect to the time, like this:
And if we take the derivate we got:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
