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.

Answer:

109200

Step-by-step explanation:

Jessica needs another 52.8 cm^3 of material to make the other prism.

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.

Answer:

y=-3/2x-3

Step-by-step explanation:

For perpendicular lines,the product of their slopes is -1 this m1•m2=-1

For the given line 3y=7+2x

y=7/3+⅔x,the slope is ⅔

For the unknown line since the y-intercept is -3 then y=mx-3

compare the slopes of both lines

m•⅔=-1

m=-3/2

hence the the perpendicular line has the equation

y=-3/2x-3

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:

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]

Answer:

g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)

Step-by-step explanation:

So g(x) has the greater value when x = 2, g(2) is 7 greater than f(2)

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%.

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.

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.
