Answer:
6π inches/min
Step-by-step explanation:
he tip of the second hand makes a complete circle in
60 sec, or 1min
The length of this circle is the circumference, C
C=2πr
Given: r=8 in
C= 2π×8 =16π
C= 16π
The linear velocity is 6π/1 = 6π inches/min

Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
Answer:
Test statistic =1.30
Step-by-step explanation:
Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.
Men Women Difference
Sample size n 60 120
Proportion p_1, p_2 0.45 0.35 0.10
60 120 180
0.45 0.35 0.383333333
27 42 69
p = 0.3833
Std error for proportion difference = 
Test statistic =

Answer:
x = -8 please mark brainliest
Step-by-step explanation:
Pull out like factors :
-x - 8 = -1 • (x + 8)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-8 = 0
Add 8 to both sides of the equation :
-x = 8
Multiply both sides of the equation by (-1) : x = -8
