industrial costs A power plant is located near a river, where the river is 800 ft wide. Running a cable from the plant to a location in the city, 2 miles (mi) downstream on the opposite side, costs $ 180 per ft across the river and $ 100 per ft ashore along the riverbank .
a) Suppose the cable runs from the plant to point Q, on the opposite side, which is x ft from point P, directly opposite the plant. Write a function C (x) that indicates the cost of laying the cable in terms of the distance x.
b) Generate a table of values to determine if the cheapest location for point Q is less than 2000 ft or greater than 2000 ft from point P.
Answer:
See attached
Step-by-step explanation:
All answers in one graph, refer to attached
The function we need is
C(x) = 100(2*5280 - x) + 180[tex]\sqrt{800 +x^2}[/tex], where 2*5280= 2 milesTable included as well
The vertex is about x = 19 ft which corresponds the minimum cost
Any other value, including negative reveal greater cost
Note. there is a bit confusion over 2 miles or 2000 ft, but the graph is going to be same in shape and vertex for x, the value for cost will be differentFind the linear function,

82(9) = 18(x)
x = 738 / 18
x = 41 y/o
in the diagram the value of sin P is
You divide the opposite over the hypotenuse
sin(angle) = opposite/hypotenuse
With respect to reference angle P, the opposite side is QR = 5 since it is the leg furthest from the angle P.
The hypotenuse is always the longest side and always opposite the 90 degree angle (the largest angle of any right triangle).
2. Find the product of 2/7 x 5/6
A. 5/21
B. 7/42
C. 9/16
D. 10/13
3. Find (-4/6) (7/10)
A. -28/45
B. -14/25
C. -7/50
D. 17/50
Multiply the numerators together and the denominators:
2/7 x 5/6 = (2x 5) / (7x6) = 10/42 this can be reduced to 5/21
The answer is 5/21
-4/5 x 7/10 = (-4x7) / (5x 10) = -28/50
This can reduce to -14/25

If one student is chosen at random, Find the probability that the student got a C: Correct Find the probability that the student was female AND got a "C": Correct Find the probability that the student was male OR got an "B": Correct If one student is chosen at random, find the probability that the student got a 'C' GIVEN they are female:______.
Answer:
Kindly check explanation
Step-by-step explanation:
________A___ B___ C___ Total
Male____ 9___13___ 6____ 28
Female_ 20__ 19___ 2____ 41
Total___ 29__ 32___ 8____ 69
If one student is chosen at random,
Find the probability that the student got a C:
P(getting C) = (number of C's) / total number
P(getting C) = 8 / 69
Find the probability that the student was female AND got a "C":
P(female and C):
(number of female who got C / total number)
= 2 / 69
Find the probability that the student was male OR got an "B":
P(male OR B) :
(Number of males or B) = (28 + 32) - 13 = 47
= 47 / 90
find the probability that the student got a 'C' GIVEN they are female:______.
P(C given they are female) :
This is the proportion of females who got C
Total Number of females = 41
Females who got C = 2
Hence,
P(C given they are female) = 2 / 41
In an assessment of the quality of the electrical power system, one measure of quality is the degree to which voltage fluctuations cause light flicker in the system. The perception of light flicker x when the system is set at 380kV was measured periodically (over 10-minute intervals). For transformers supplying heavy industry plants, suppose the light flicker distribution was found to follow (approximately) a normal distribution with % and . If the perception of light flicker exceeds %, the transformer is shut down and the system is reset. How likely is it for a transformer supplying a heavy industry plant to be shut down due to light flicker?

An older person is 5 years older than six times the age of a younger person. The sum of their ages is 26. Find their ages.
Let x be the age of the younger person.
The older person would be 6x +5 (5 years older than 6 times)
Now add to equal the sum:
x + 6x +5 = 26
Combine like terms:
7x +5 = 26
Subtract 5 from both sides:
7x = 21
Divide both sides by 7:
x = 3
Now you can subtract the age of the younger person from the total age:
26-3 = 23
The ages are 3 and 23
Answer:
3 and 23

Como puedo poner 2 3/5 en decimal
When turning a fraction into a decimal, any whole numbers comes before the "." and the fraction will become after the ".".
To make it simple, turn the fraction into a "over 100" fraction to make it easier.
Multiple both numeriator and denominator by a specific number, to turn the denominator into a 100. You must times the numeriator as well since your changing the denominator.
100 / 5 = 20
So now, multiple both sides of the fraction by 20.
3 x 20 = 60
5 x 20 = 100
2 60/100
Now, put the whole number in front of the decimal symbol.
2.___
Now, take the numeriator and put it behind the decimal symbol.
2.60
So, when turning 2 3/5 into a decimal, it is 2.60.
