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]

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:

x = 12

Step-by-step explanation:

a² + b² = c²

Answer:

Step-by-step explanation:

Fourth row is least accurate.

Answer:

B x 0.16 = T

If the bill is $ 145, the tip will be $ 23.2.

Step-by-step explanation:

Since Jack’s BBQ has a policy of adding a 16% tip if there is a party of 8 or more, to write an equation to represent the relationship between tip (t) and the bill (b), the following reasoning must be performed:

B x 0.16 = T

B is the value of the bill after consumption.

In turn, to determine how much the tip would be if the bill is $ 145, the following calculation must be performed:

145 x 0.16 = T

23.2 = T

Thus, if the bill is $ 145, the tip will be $ 23.2.

Answer:

49

Step-by-step explanation:

Let  be the unknown number. Twice means times 2. So, the mathematical sentence should be .

Divide both sides by 2.

To remove the radical symbol, raise both sides to the second power.

Thus, the answer is 49. Twice the square root of 49 is equal to 14.

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:

For Example:  Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.

Step-by-step explanation:

To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:

a2 b

(    )2 (  )

(–2)2 (3)

(4)(3)

12

Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.

By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.

Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.

In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:

(–2) – (–4)(4)

–2 – (–16)

–2 + 16

16 – 2

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.
