Let the angle of elevation is x and the height of the rocket from the ground is y
tanx = y/15
by differentiating both sides with respect to T
sec²x·dx/dt = (dy/dt)/15
at y = 30 , the hypotenuse of the triangle = 15√5
sec²x=(15√5/15)²=5
5 dx/dt = 11/15
dx/dt = 11/75 rad/sec
Answer:
Mom === 10.25
Daughter === 3.25
Step-by-step explanation:
Let’s the mom age be 7+x and the daughters age be x. Put it in a linear equation 7+x=5(4+x).
open the bracket which will give you 7+x=20+5x.
collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25
Answer:
x < -8
Step-by-step explanation:
3 - (2x - 5) < -4(x + 2)
-2x + 8 < -4x - 8
-2x < -4x - 16
2x < -16
x < -8
Best of Luck!
State A:
21,22,22,23,23,23,24,24,25
minimum = 21
Q1 = 22
Q2(median) = 23
Q3 = 24
maximum = 25
IQR = Q3 - Q1 = 24 - 22 = 2
state B:
20,20,21,22,23,23,24,46,50
minimum = 20
Q1 = (20 + 21)/2 = 20.5
Q2(median) = 23
Q3 = (24 + 46)/2 = 35
maximum = 50
IQR = 35 - 20.5 = 14.5
I do not believe they are symmetrical....I think state B is skewed to the right
