Answer:
Question A: 14
Question B: 30min
Step-by-step explanation:
is x(4x^2+8x+12) completely factored? If not how else can it be factored ?
A. Yes the polynomial is completely factored
B. No 4 can be factored from each term of the trinomial and the resulting trinomial can be factored into two binomials.
C.no 4 can be factored from each term of the trinomial
D. No the trinomial 4x^2+8x+12 can be factored into two binomials
No 4 can be factored from each term of the trinomial. Therefore, option C is the correct answer.
What is factorization?The factorization method uses basic factorization formula to reduce any algebraic or quadratic equation into its simpler form, where the equations are represented as the product of factors instead of expanding the brackets. The factors of any equation can be an integer, a variable, or an algebraic expression itself.
The given polynomial is x(4x²+8x+12).
Here, in the trinomial 4x²+8x+12, 4 is common factor in each term.
So, group and factor out the greatest common factor (GCF), then combine.
That is, 4(x²+2x+3)
Now, x(4x²+8x+12)= 4x(x²+2x+3)
Therefore, option C is the correct answer.

The Law and Order detectives enter a house at 11:30 am and found a man on the floor murdered. They take his body temperature finding to be 91.8 F. The body is taken to the morgue and at 12:30 pm the body temperature is 84.4 F. Using an exponential model for the body temperature, to the nearest minute, what time was he killed. Normal body temperature is 98.6.
Answer:
Time of murder = 10:39 am
Step-by-step explanation:
Let the equation of exponential function representing the final temperature of the body after time 't' is,
f(t) = [tex]a(e)^{nt}[/tex]
Here, a = Initial temperature
n = Constant for the change in temperature
t = Duration
At 11:30 am temperature of the body was 91.8°F.
91.8 = [tex]98.6(e)^{nt}[/tex] --------(1)
Time to reach the body to the morgue = 12:30 pm
Duration to reach = 12:30 p.m. - 11:30 a.m.
= 1 hour
Therefore, equation will be,
84.4 = [tex]91.8(e)^{n\times 1}[/tex]
eⁿ = [tex]\frac{84.4}{91.8}[/tex]
ln(eⁿ) = ln(0.9194)
n = -0.08403
From equation (1),
91.8 = [tex]98.6(e)^{-0.08403t}[/tex]
[tex](e)^{0.08403t}=\frac{98.6}{91.8}[/tex]
[tex]ln[(e)^{0.08403t}]=ln[\frac{98.6}{91.8}][/tex]
0.08403t = 0.07146
t = 0.85 hours
t ≈ 51 minutes
Therefore, murder was done 51 minutes before the detectives arrival.
Time of murder = 11:30 - 00:51
= 10:90 - 00:51
= 10:39 am

Vincent Pancozzi borrowed $750 on a one-year simple interest loan at 17% interest. The monthly payments were $63.57. Find the amount of interest, amount applied to the principal, and the new balance for the first monthly payment.
Answer:
Amount of interest = 127.5
Amount applied to main = 877.5
New balance for the first monthly payment = 813.93
Step-by-step explanation:
Since Vincent Pancozzi borrowed $ 750 on a one-year simple interest loan at 17% interest and the monthly payments were $ 63.57, to find the amount of interest, amount applied to the principal, and the new balance for the first monthly payment the following calculations must be made:
Amount of interest: 750 x 0.17 = 127.5
Amount applied to main: 750 + 127.5 = 877.5
New balance for the first monthly payment: 877.5 - 63.57 = 813.93

A study of the career paths of hotel general managers sent questionnaires to an SRS of 160 hotels belonging to major U.S. hotel chains. There were 103 responses. The average time these 103 general managers had spent with their current company was 11.7 years. Give a 99% confidence interval for the mean number of years general managers of major-chain hotels have spent with their current company. (Take it as known that the standard deviation of time with the company for all general managers is 3.6 years.)
Answer:
(10.78483, 12.61517)
Step-by-step explanation:
It is given that the genera mangers of few hotels were sent some questionnaires for conducting a study for the career paths in the major hotel chains of the United States.
Number of hotels = 160
Number of response received = 103
The average number of years these general mangers was in their current hotels, [tex]$\bar x$[/tex] = 11.7 years
Confidence Interval, CI = 0.99
Therefore,
a = 0.01, |Z(0.005)| (from standard normal table)
∴ 99% of CI = [tex]$\bar x \pm Z \times \frac{s}{\sqrt n}$[/tex]
[tex]$= 11.7 \pm 2.58 \times \frac{3.6}{\sqrt {103}}$[/tex]
[tex]$(10.78483, 12.61517)$[/tex]

Answer:
242 ft²
Step-by-step explanation:
The shape can be decomposed to give us a trapezium and a rectangle
Area of the shape = area of the trapezium + area of the rectangle
✔️Area of the trapezium = ½(a + b)h
a = 14 ft
b = 20 ft
h = 13 - 7 = 6 ft
Area = ½(14 + 20)*6
Area of trapezium = 102 ft²
✔️Area of rectangle = L*W
L = 20 ft
W = 7 ft
Area = 20*7 = 140 ft²
✔️Area of the shape = 102 + 140 = 242 ft²

9x = 5x + 12. We have to make sure it's right.
9x3= 27.
27x3=27.
5x3= 15.
27=15+12.

The following formula gives the temperature's measure in degrees Fahrenheit F, where C is the measure
in degrees Celsius:
F=
9
C + 32
5
Rearrange the formula to highlight the measure in degrees Celsius.
Answer:
The rearrenged formula is [tex]C = \frac{5(F - 32)}{9}[/tex]
Step-by-step explanation:
Celsius to Fahrenheit:
To realize the conversion of the temperature in degrees Celsius to degrees Fahrenheit, we use the following equation:
[tex]F = \frac{9C}{5} + 32[/tex]
Rearrange the formula to highlight the measure in degrees Celsius.
We want to find C in function of F. So
[tex]F = \frac{9C}{5} + 32[/tex]
[tex]\frac{9C}{5} = F - 32[/tex]
[tex]C = \frac{5(F - 32)}{9}[/tex]
