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]

hey buddy,

●15x + 5y = 25

5y = 25-15x

y = (25 - 15x) /5

y = 5 - 3x

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:

[tex]m = \frac{5}{7}[/tex]

[tex]m_2 = \frac{5}{21}[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (7,5)[/tex]

[tex](x_2,y_2) = (21,15)[/tex]

Using the available details, the solution goes thus:

Solving (a): The slope (m) of this line:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

This gives:

[tex]m = \frac{15 - 5}{21 - 7}[/tex]

[tex]m = \frac{10}{14}[/tex]

Simplify:

[tex]m = \frac{5}{7}[/tex]

Solving (b): Another line with 1/3 of the slope.

This is calculated using:

[tex]m_2 = \frac{1}{3} * m[/tex]

[tex]m_2 = \frac{1}{3} * \frac{5}{7}[/tex]

[tex]m_2 = \frac{5}{21}[/tex]

Answer:

The southwest corner of the garden will be 2 feet south and 3 feet west of the tree. A circle has a center at (3,5). What is the area of the circle to the nearest tenth of a square unit? Which of the following could be the vertices of the triangle? A garden that is 5 feet by 6 feet has a walkway that is 2 feet wide around it.

Answer:

7 months.

Step-by-step explanation:

1250-800=450. so more than 450 has to be spent and that comes out to 7 months where you'll spend 455

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.

Step-by-step explanation:

Answer:

96π

Step-by-step explanation:

The transformation x = au , y = bv (a>0, b>0) can be re-written as;

[tex]\dfrac{x}{a}= u , \dfrac{y}{b}=v ;[/tex] which maps the circular region u² + v² ≤ 1 into the elliptical region

[tex]\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}\le 1[/tex]

Integrating and transforming the elliptical region into a circular region;

[tex]\int \int _R \sqrt{16x^2+9y^2}\ dA[/tex]

here;

R = region enclosed by the ellipse.

[tex]\dfrac{x^2}{9}+\dfrac{y^2}{16}=1[/tex]

Let x = 3u ; y = 4v

Jocobian = J(x,y)

                [tex]= \left[\begin{array}{ccc}\dfrac{\partial x}{\partial u}&\dfrac{\partial x}{\partial v}\\\dfrac{\partial y}{\partial u}&\dfrac{\partial y}{\partial v}\\\end{array}\right] \\ \\ \\ \\ = \left[\begin{array}{ccc}3&0\\0&4\\\end{array}\right] \\ \\ \\ = 12[/tex]

So;

[tex]\int \int_R \sqrt{16x^2+9y^2 \ dA}= \int \int _D\sqrt{16(4u)^2+9(3v)^2} \ |J| dudv \\ \\ \\= 12 \int \int _D \sqrt{x^2 +v^2} \ \ (12) dudv \\ \\ \\ =144 \int \int _D \sqrt{x^2 +v^2} \ \ dudv[/tex]

Using polar coordinates;

[tex]u = rcos \theta ; v = rsin \theta \\ \\ \implies u^2+v^2 = r^2 ; dudv = rdr \theta \\ \\ limits :\\ \\ 0 \le r \le 1, 0\le \theta \le 2 \pi[/tex]

∴

[tex]\int \int _R \sqrt{16x^2 + 9y^2 }\ dA[/tex]

[tex]= 144 \int ^{2 \pi}_{0} \int ^{1}_{0} \ r (rdrd \theta) \\ \\ = 144 \int ^{2 \pi}_{0} \int ^{1}_{0} \ r^2drd \theta \\ \\ = 144 \int ^{2 \pi}_{0}(\dfrac{r^3}{3})^1_0 r d \theta \\ \\ = 144 ( \dfrac{1}{3}) \int ^{2 \pi}_{0} \ d \theta \\ \\ = 144(\dfrac{1}{3}) ( 2 \pi) \\ \\ \mathbf{= 96 \pi}[/tex]

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

14
