Answer:
A. 10.125 minutes
Step-by-step explanation:
A stopwatch measures time to the hundredth of a second. Which of the following quantities is not possible using this measurement tool?
A. 10.125 minutes
B. 10.125 seconds
C. 10.12 seconds
D. 10.1 seconds
The stopwatch measures time to the hundredth of a second.
Option A. Measures the time to thousandth of a minutes
Option B. Measures time to thousandth of a second
Option C measures time to hundredth of a second
Option C measures time to tenth of a second.
Option A. 10.125 minutes is the quantity which is not possible using the stopwatch because it is in MINUTES.
Option B 10.125 seconds can be rounded up to 10.13 seconds (hundredth of seconds).

Answer:
x³ - 8x² - 11x + 148
Step-by-step explanation:
Given that x = 6 + i is a root then x = 6 - i is also a root
Complex roots occur as conjugate pairs.
The factors are therefore (x - (6 + i)) and(x - (6 - i))
Given x = - 4 is a root then (x + 4) is a factor
The polynomial is the product of the factors, that is
p(x) = (x + 4)(x - (6 + i))(x - (6 - i))
= (x + 4)(x - 6 - i)(x - 6 + i)
= (x + 4)((x - 6)² - i²)
= (x + 4)(x² - 12x + 36 + 1)
= (x + 4)(x² - 12x + 37) ← distribute
= x³ + 4x² - 12x² - 48x + 37x + 148
= x³ - 8x² - 11x + 148

Variation Constant: k = 7/6
y = 245/6 when x = 7 and z = 5
====================================
Explanation:
"y varies jointly as x and z" means that y = kxz
We have (x,y,z) = (4,14,3) as one triple, so,
y = kxz
14 = k*4*3
14 = 12k
12k = 14
k = 14/12
k = 7/6 is the variation constant
The equation goes from y = kxz to y = (7/6)xz
----------------
Plug in x = 7 and z = 5 to find y
y = (7/6)xz
y = (7/6)*7*5
y = (7/6)*(7/1)*(5/1)
y = (7*7*5)/(6*1*1)
y = 245/6
