12. The cost, in dollars, of operating a
machine per day is given by the formula
C = 3t2 – 96t + 1014, where t is the time
the machine operates, in hours. What is
the minimum cost of running the machine?
For how many hours must the machine run
to reach this minimum cost?
The minimum cost of running the machine is $246. The time for minimum cost will be 16 hours.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the cost, in dollars, of operating a machine per day is given by the formula C = 3t² – 96t + 1014.
The minimum cost will be calculated as:-
d/dt ( 3t² – 96t + 1014 ) = 0
6t -96 = 0
6t = 96
t = 16 hours
The minimum cost is calculated as:-
C = 3t² – 96t + 1014
C = 3 ( 16)² - 96 x 16 + 1014
C = 768 - 1536 + 1014
C = $246

A man leaves home at 20:15 hrs and
reaches his destination at 06:00 hrs the
following day. How many hours did the
journey take?
Answer:
9 hours and 45 mins
Step-by-step explanation:
First, this is in army time. (Just so you know!) Also, it goes to 24 hours.
What you would do is add 45 mins to get to a single hour: so 20:15 + 45 = 21:00, then add 3 to get to 24:00 or 12:00 am, then add 6 more hours to get to 6:00 hours. So the final answer is 9 hours and 45 mins

The price of an article is increased from Rs 75 to Rs 78. Find the percentage increase in the price of the article.
WITH FULL CALCULATION PLEASE!!!!!
======================================================
Work Shown:
A = old value = 75
B = new value = 78
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (78-75)/75 ] * 100%
C = (3/75) * 100%
C = 0.04 * 100%
C = 4%
The positive C value means we have a percent increase.
The price has increased by 4%

what is the degree of polynomial
f (x) = 2x² - 5x+6 ?
Answer:
2
Step-by-step explanation:
The degree of a polynomial is its highest exponent value: in this case, thats just two!
Answer:
degree 2
Step-by-step explanation:
The degree of a polynomial is determined by the largest value of the exponent attached to the variable.
f(x) = 2x² - 5x + 6 ← has the term 2x² with exponent 2 ( largest ), then
f(x) is a polynomial of degree 2

What is the image point of (2,7) after a translation left 4 units and up 2 units?
Please hurry ASAP no links
Answer:
Coordinates of the image point → (-2, 9)
Step-by-step explanation:
If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,
(x, y) → (x - h, y + k)
Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,
(2, 7) → (2 - 4, 7 + 2)
→ (-2, 9)
Coordinates of the image point → (-2, 9)

Three candidates were running for class president. Of the 250 students eligible to vote, 75 voted for Carlos and 32% of the students voted for LaToya. Of thsoe who didn't vote for Carlos or LaToya, 60% voted for Stephanie and the rest of the students chose not to vote.
Part 1: What percent of the eligible students voted for Carlos?
Part 2: How many votes did LaToya receive?
Part 3: How many votes did Stepanie recieve?
Part 4: Who won the election?
Answer:
Part 1) 30%
Part 2) 80 students
Part 3) 57 votes
Part 4) LaToya
Step-by-step explanation:
75 divided by 250 = 0.30 = 30%
32% = 0.32 and then 0.32 times 250 = 80 students
250 - 75 - 80 = 95 students that didn't vote for Carlos or LaToya. Then 0.60 times 95 = 57
LaToya had 80 votes, the most votes.
Which expression is equivalent to 5(a + b) ?

B. a + 5b
C. 5a + b
D. a(5 + b)
Answer:
A is the answer

Step-by-step explanation:
Her location is not specified beyond living near a river, therefore we cannot be sure of earthquakes, she does not live near a body of water large enough to cause a tsunami, and it did not specify that she was near a volcano therefore we make the assumption that she is not at risk for that. Therefore, leaving a flood as our option.

Harold found a job through a friend that works in HR for a large company. The job pays a yearly salary of $39K. What is the weekly salary based on this annual salary?
Answer:
Weekly salary of Harold = $750 (Approx.)
Step-by-step explanation:
Given:
Annual salary of Harold = $39K = $39,000
Find:
Weekly salary of Harold
Computation:
Number of weeks in a year = 365 / 7
Number of weeks in a year = 52.1425
Number of weeks in a year = 52 week (Approx.)

Weekly salary of Harold = 39,000 / 52
Weekly salary of Harold = 750
Weekly salary of Harold = $750 (Approx.)
A counter top is in the shape of a trapezoid. The lengths of the bases are 70 1/2 and 65 1/2 inches long. The area of the counter top is 1,244 square inches. Write and solve an equation to find the height
Answer:
height = (area x 2) / sum of bases
18.29 inches
Step-by-step explanation:
height = area x 2 / sum of bases
sum of lengths = 70 1/2 = 65 1/2 = 136
(1244 X 2) / 136 = 18.29
