Answer:
Y= -1.5x+3
Step-by-step explanation:
(Y-Y1)=m(x-x1)
0-3=m(2-0)
m= -1.5
Y= -1.5x+B
when y=3 and x=0 b=3
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mv

=

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v

Step-by-step explanation:
Answer:
40.1 < μ < 43.3
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
At 99% confidence and 38 degrees of freedom, CV = 2.712.
SE = s / √n
SE = 3.86 / √39
SE = 0.618
So the margin of error is:
ME = 2.712 × 0.618
ME = 1.7
So the 99% confidence interval of the population mean is:
μ = 41.7 ± 1.7
40.0 < μ < 43.4
Closest answer is the first one.
