Which describes the number and type of roots of the equation x^3 + 121x = 0?
a. 2 real roots, 1 imaginary root
b. 1 real root, 2 imaginary roots
c. 3 real roots
d. 3 imaginary roots
Answer:
b; 1 real root and 2 imaginary roots
Step-by-step explanation:
From here, we have
x(x^2 + 121) = 0
x = 0 (1 real root)
or
x^2 + 121 = 0
x^2 = -121
x = √(-121) (2 imaginary roots)
so is would be two complex numbers from above

Joseph's workshop is 12 feet by 7 feet. If the drawing of the workshop has a scale of 1inch = 2 feet, what are the dimensions of the drawing? (enter your answer with a comma separating the two numbers)
Answer:
6, 3.5.
Step-by-step explanation:
Start with the 12 foot measurement. 1 inch of the drawing represents 2 feet, so divide 12 feet by 2 to find out how many inches represent 12 feet. 12/2 is 6. Do the same with the 7 foot measurement. 7/2 is 3.5, so the drawing of the 7 foot side will be 3.5 inches.
According to a medical study, 15% of people will experience an adverse side effect
within one hour after taking a particular experimented drug. Suppose you survey 12
people who participated in the study. What is the probability at most 2 people will
have adverse side effect?
A)O 0.594
B)0.646
C)0.736
D)0.264
Answer:
c
Step-by-step explanation: trust me
The probability that the people that would have adverse effect are at most 2 is 0.736
What is probability?This is the theory that is used in statistics to explain the chances of an event occuring.
To solve for the probability of at most 2, we solve for 1- P(1) + P(2)
= 1/12 + 2/12
= 1 - 0.083+0.167
= 0.73
Therefore the probability that the most people with adverse effect is 2 is 0.736. Option c is correct.

First, let's start with the formula for the surface area of a rectangular prism.
A = 2(wl + hl + hw)
Plug in everything that you know.
A = 2[(4 · 5) + (7 · 5) + (7 · 4)]
Simply the equation.
A = 2(20 + 35 + 28)
A = 2(73)
A = 146

Answer:
the total of angle's in traingle is 180
so 85+53+c=180
c=180-138
c=42
Step-by-step explanation:
180° = m∠A + m∠B + m∠C
180° = 85° + 53° + m∠C
180° = 138° + m∠C
m∠C = 180° - 138°
= 42°
