Answer:

[tex]2a - b -c[/tex]

Step-by-step explanation: We know that:

[tex]log_{2} 5 = a\\log_{2} 3 = b\\log_2 7 = c\\[/tex]

and we want:

[tex]log_2 \frac{25}{21}[/tex].

We can form the numerator using just the first fact (since 5^2 is 25) and the denominator using the latter two (since 3*7 = 21).

[tex]log_2 \frac{25}{21} = log_2 \frac{5^2}{3*7}.[/tex]

The logarithm of a division can be expanded by subtracting the numerator and denominator (while still keeping the log). The logarithm of a product can be expanded by adding the terms while keeping the log. If the logarithm is raised to a power, we can bring it down as a factor:

[tex]log_2 \frac{5^2}{3*7} = log_2(5)^2 - log_2 (3*7) = 2 log_2(5) - (log_2 3 + log_2 7)[/tex]

[tex]= 2 log_2(5) - log_2 3 - log_2 7[/tex] .

Substituting the variables:

[tex]2 log_2(5) - log_2 3 - log_2 7 = 2a - b - c[/tex]

Answer:

0.78125g

Step-by-step explanation:

Since there are 35 days in 5 weeks, 7 half-lives of Bismuth-210 will take place. To solve for that, you can divide 100g by 2, 7 times or simply: [tex]\frac{100}{2^{7}}[/tex]

[tex]\frac{100}{2} =50\\\frac{50}{2} =25\\\frac{25}{2} =12.5\\\frac{12.5}{2} =6.25\\\frac{6.25}{2} =3.125\\\frac{3.125}{2} =1.5625\\\frac{1.5625}{2} =0.78125[/tex]

Answer:

2142

Step-by-step explanation:

The range is the difference between the biggest and smallest number so for this set it would be 3113-971=2142.

Answer:

The answer is "[tex]x_k= -\frac{9}{16} (-2)^k + \frac{9}{16} 2^k +\frac{3}{8} k\times 2^k\\\\[/tex]"

Step-by-step explanation:

[tex]\to F(Z)=\frac{3z(z-1)}{z^3-2z^2-4z+8}\\\\\to \frac{F(Z)}{z}=\frac{3z(z-1)}{z(z^3-2z^2-4z+8)}\\\\\to \frac{F(Z)}{z}=\frac{3(z-1)}{(z^3-2z^2-4z+8)}\\\\\to \frac{F(Z)}{z}=-\frac{9}{16} \frac{1}{z+2} + \frac{9}{16} \frac{1}{z-2} +\frac{3}{4} \frac{1}{(z-2)^2}\\\\\to F(Z)=-\frac{9}{16} \frac{z}{z+2} + \frac{9}{16} \frac{z}{z-2} +\frac{3}{4} \frac{z}{(z-2)^2}\\\\\to x_k= -\frac{9}{16} (-2)^k + \frac{9}{16} 2^k +\frac{3}{8} k\times 2^k\\\\[/tex]

Answer:

f(0) is approximately equal to 7.07

Step-by-step explanation:

All you need to do here is substitute a zero wherever you see an x in the equation, giving us:

[tex]f(0) = 2(0)^2 + 5\sqrt{0 + 2}\\f(0) = 5\sqrt{2} \\f(0) \approx 5 \times 1.414\\f(0) \approx 7.07[/tex]

Answer:

  3)  (0, 0)

  4)  (-1, 2)

Step-by-step explanation:

I find a graphing calculator provides a quick solution to a system of linear equations.

3) The solution is (x, y) = (0, 0)

4) The solution is (x, y) = (-1, 2)

__

In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.

Answer:

$551.25

Step-by-step explanation:

1. Encuentre el 25% de $735:

0.25 x 735 = 183.75

2. Reste este número del precio original, $735:

735 - 183.75 = 551.25

The lady paid $551.25 after the 25% discount on merchandise.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a 25% discount is advertised on all merchandise. A lady bought a merchandise for $735.

Assume that she paid $x after the 25% discount. Then, we can write -

[x] = 735 - 25% of 735

[x] = 735 - (25/100) x 735

[x] = 735 - (1/4) x 735

[x] = 735(1 - 1/4)

[x] = 735 x 3/4

[x] = 551.25

Therefore, the lady paid $551.25 after the 25% discount on merchandise.
