Using unitary method, the manufacturing company will take 1 hour 40 minutes to create a total of 180 products.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of products generated by old assembly line in 60 minutes = 48
Number of products generated by old assembly line in 1 minute = 48/60 = 0.8
Number of products generated by new assembly line in 60 minutes = 60
Number of products generated by new assembly line in 1 minutes = 60/60 = 1
Total production in 1 minute = 1 + 0.8 = 1.8
Time taken to produce 180 products = 180/1.8 = 100 minutes = 1 hour 40 minutes

g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)
Step-by-step explanation:
From the graph, f(2) = 1
g(2) = 0.5(4)² = 8
So g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)

Step-by-step explanation:
Alejandro bought a bond with a face value of $5,000. The term of the bond is 2 years. He bought the bond at a 4 percent discount from the face value. The bond pays 4 percent annual interest, and Alejandro will receive four semiannual payments. When the bond is redeemed at maturity, the total return (profit) will be $______.00. The total return on investment will be _____%. (Round return on investment percentage to one decimal place.)
1. When the bond is redeemed at maturity, the total return (profit) for Alejandro will be $600.00.
2. The total return on investment will be 12.5%.
What is the return on investment?The return on investment is a profitability measure that shows the rate of an investment's profit versus the cost.
The return on investment can be computed by subtracting the initial investment cost from the terminal value of the investment, then dividing the net return by the initial investment cost, then multiplying it by 100.
Data and Calculations:Face value of bond = $5,000
Price paid for bond = $4,800 ($5,000 x 96%)
Bond discount = $200 ($5,000 x 4%)
Maturity period = 2 years
Interest rate = 4%
Semi-annual interest receipts = $100 ($5,000 x 4% x 1.2)
Total interest receipts = $400 ($100 x 4)
Total return (profit) from the bond = $600 ($400 + $200)
Total return on investment = 12.5% ($600/$4,800 x 100)
Thus, the bond investment yields $600 at the end of the maturity period, which is 12.5% of the initial investment.

Factor the greatest common factor (GCF) from each polynomial. 2x^4 +8x^3+2x
Answer:
2x(x^3+4x^2+1)
Step-by-step explanation:
Answer:
2x(x³ + 4x² + 1)
Step-by-step explanation:
The coefficients are 2, 8, 2.
The GCF of the coefficients is 2
The variable parts are x^4, x^3, x
The GCF of the variable parts is x
The GCF of the entire polynomial is 2x
Now we factor out 2x:
2x^4 + 8x^3 + 2x = 2x(x³ + 4x² + 1)
Jessica has 300 cm³ of material. She uses 12.6 cm³ to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 3. How much more material does Jessica need in order to make the second prism? Select from the drop-down menu to correctly complete the statement. Jessica needs an additional Choose... cm³ of material to make the second prism.
Jessica needs another 52.8 cm^3 of material to make the other prism.
How much material will she use?For a right triangular prism of base B, height H, and length L, the volume is:
V = (1/2)*B*L*H
Now, we know that the first triangle has a volume of 12.6cm^3, then we can write:
V = 12.6cm^3 = (1/2)*B*L*H
If we dilate the prism with a scale factor of 3, the new dimensions are:
B' = 3B
L' = 3L
H' = 3H
Then the new volume is:
V' = (1/2)*(3B)*(3L)*(3H) = 27*(1/2)*B*L*H
And (1/2)*B*L*H is the original volume, so we can write:
V' = 27*V = 27*(12.6cm^3) = 340.2 cm^3
And she has 300cm^3 and she used 12.6cm^3, so the amount of material that she has left is:
M = 300 cm^3 - 12.6 cm^3 = 287.4 cm^3
Then the amount of material that she needs is:
340.2 cm^3 - 287.4 cm^3 = 52.8 cm^3
So Jessica needs another 52.8 cm^3 of material to make the other prism.

=============================================
Explanation:
Recall that the pythagorean trig identity is [tex]\sin^2 x + \cos^2x = 1[/tex]
If we were to isolate sine, then,
[tex]\sin^2 x + \cos^2x = 1\\\\\sin^2 x = 1-\cos^2x\\\\\sin x = \sqrt{1-\cos^2x}\\\\[/tex]
We don't have to worry about the plus minus because sine is positive when 0 < x < pi/2.
Through similar calculations, [tex]\cos x = \sqrt{1-\sin^2x}\\\\[/tex]
Cosine is also positive in this quadrant.
-------------
So,
[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}\\\\\frac{\sin x}{\sin x}+\frac{\cos x}{\cos x}\\\\1+1\\\\2[/tex]
Therefore,
[tex]\frac{\sqrt{1-\cos^2x}}{\sin x}+\frac{\sqrt{1-\sin^2x}}{\cos x}=2[/tex]
is an identity as long as 0 < x < pi/2
Answer:
2
Step-by-step explanation:
[tex]=\frac{\sqrt{1-cos^{2}x }}{sinx} +\frac{\sqrt{1-sin^{2}x } }{cosx} \\\\When \:0 < x < \frac{\pi }{2} \\\\=\frac{\sqrt{sin^{2}x } }{sinx} +\frac{\sqrt{cos^{2}x } }{cosx} \\\\=\frac{sinx}{sinx} +\frac{cosx}{cosx} \\\\=1+1\\\\=2[/tex]
Here we use the formula sin²x=1-cos²x and cos²x=1-sin²x.

In 2010, the population of a city was 108,000. From 2010 to 2015, the
population grew by 7.7%. From 2015 to 2020, it fell by 6.1%. To the nearest
100 people, what was the population in 2020?
Answer:
109,200 people
Step-by-step explanation:
First change all the percentages into decimals. Then multiply 108,000 by 1.077, because it is 7.7% of the population, while also including the original population. The product of this is 116,316. Then, if you want to find the percent decrease, it would be something out of 100, so 100-6.1=93.9. Changing that into decimal form, 0.939, and multiplying it by 116,316, you get 109,220, which rounds to 109,200.

109200
