Step-by-step explanation:

The domain of a function is the range of x such that the function is defined.

Now we know the function

[tex]f(x) = \frac{1}{ {x}^{2} + 3x - 4 }[/tex]

is only defined when the denominator is not zero, in other words, when

[tex] {x}^{2} +3x - 4 \neq \: 0[/tex]

or

[tex](x + 4)(x - 1) \neq0[/tex]

[tex]x \ne-4 [/tex]

and

[tex]x \neq +1[/tex]

Answer:

[tex]\boxed {\boxed {\sf ( -9, \frac{11}{2}) }}[/tex]

Step-by-step explanation:

We are asked to find the midpoint of a segment. We essentially calculate the average of the x-coordinates and the y-coordinates using the following formula.

[tex]( \frac {x_1+x_2}{2}, \frac{ y_1 + y_2}{2})[/tex]

In this formula, (x₁ , y₁) and (x₂ , y₂) are the endpoints of the segment. For this problem, the 2 endpoints are (-12, 12) and (-6, -1). If we match the variable and the corresponding value, we see that:

Substitute the values into the formula.

[tex]( \frac{-12 + -6}{2}, \frac{12 + -1} {2} )[/tex]

Solve the numerators.

[tex]( \frac{-18}{2}, \frac{11}{2})[/tex]

Divide.

[tex]( -9, \frac{11}{2} )[/tex]

The midpoint of the segment is [tex]\bold {( -9, \frac{11}{2} )}[/tex].

Not counting y as a vowel: 5/26  or a  19.23% chance

Step-by-step explanation:

There are a total of 26 letters in the alphabet.

There are 5 vowels (a, e, i, o, u)

Picking a vowel has a 5 in 26 chance of occurring.

Answer:

Angle ABD = 60

Step-by-step explanation:

Angle ABD = angle ABC + angle CBD

We are given that angle ABC = 25 and angle CBD = 35

So angle ABD = 25 + 35 = 60

Answer:

60

Step-by-step explanation:

to find the length of the entire angle, you will have to add both seperated sides to find it.

<ABC = 25

<CBD = 35

25 + 35 = 60

So, <ABD = 60

[tex]\sf 12 \cdot 2^{\frac{1}{2}}+16 \cdot 5^{\frac{1}{2}}+8 \cdot 6^{\frac{1}{2}}[/tex]

Step-by-step explanation:

Perimeter of a rectangle

Perimeter = 2(width + length)

Given information:

  [tex]\textsf{width} = 3\sqrt{8}[/tex]

  [tex]\textsf{length} = 4\sqrt{20}+2\sqrt{24}[/tex]

Equivalent Expression 1

Substitute the given information into the formula:

[tex]\sf Perimeter = 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})[/tex]

Equivalent Expression 2

Using the distributive property law, this can also be written as:

[tex]\sf Perimeter = 2(3\sqrt{8})+2(4\sqrt{20}+2\sqrt{24})[/tex]

Equivalent Expression 3

Distribute the parentheses and simplify the radicals:

[tex]\begin{aligned}\sf Perimeter & = \sf 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})\\& = \sf 6\sqrt{8}+8\sqrt{20}+4\sqrt{24}\\& = \sf 6\sqrt{4 \cdot 2}+8\sqrt{4 \cdot 5}+4\sqrt{4 \cdot 6}\\& = \sf 6\sqrt{4}\sqrt{2}+8\sqrt{4}\sqrt{5}+4\sqrt{4}\sqrt{6}\\& = \sf 6 \cdot 2 \sqrt{2}+8 \cdot 2 \sqrt{5}+4 \cdot 2 \sqrt{6}\\& = \sf 12 \sqrt{2}+16 \sqrt{5}+8 \sqrt{6}\end{aligned}[/tex]

Equivalent Expression 4

Distribute the parentheses and rewrite the square roots as [tex]\sf \sqrt{a}=a^{\frac{1}{2}}[/tex] :

[tex]\begin{aligned}\sf Perimeter & = \sf 2(3\sqrt{8}+4\sqrt{20}+2\sqrt{24})\\& = \sf 6\sqrt{8}+8\sqrt{20}+4\sqrt{24}\\ & = \sf 6 \cdot 8^{\frac{1}{2}}+8 \cdot 20^{\frac{1}{2}}+4 \cdot 24^{\frac{1}{2}}\end{aligned}[/tex]

Equivalent Expression 5

Rewrite the square roots as [tex]\sf \sqrt{a}=a^{\frac{1}{2}}[/tex] :

[tex]\sf Perimeter=12 \cdot 2^{\frac{1}{2}}+16 \cdot 5^{\frac{1}{2}}+8 \cdot 6^{\frac{1}{2}}[/tex]

She bought more polka dot fabric

Step-by-step explanation:

you can cross multiply so 9x11=99 and 12x7=84. Since 99>84, 11/12>7/9

It looks like the integral is

[tex]\displaystyle \int_C (3x+4y)\,\mathrm dx + (2x-3y)\,\mathrm dy[/tex]

where C is the circle of radius 2 centered at the origin.

You can compute the line integral directly by parameterizing C. Let x = 2 cos(t ) and y = 2 sin(t ), with 0 ≤ t ≤ 2π. Then

[tex]\displaystyle \int_C (3x+4y)\,\mathrm dx + (2x-3y)\,\mathrm dy = \int_0^{2\pi} \left((3x(t)+4y(t))\dfrac{\mathrm dx}{\mathrm dt} + (2x(t)-3y(t))\frac{\mathrm dy}{\mathrm dt}\right)\,\mathrm dt \\\\ = \int_0^{2\pi} \big((6\cos(t)+8\sin(t))(-2\sin(t)) + (4\cos(t)-6\sin(t))(2\cos(t))\big)\,\mathrm dt \\\\ = \int_0^{2\pi} (12\cos^2(t)-12\sin^2(t)-24\cos(t)\sin(t)-4)\,\mathrm dt \\\\ = 4 \int_0^{2\pi} (3\cos(2t)-3\sin(2t)-1)\,\mathrm dt = \boxed{-8\pi}[/tex]

Another way to do this is by applying Green's theorem. The integrand doesn't have any singularities on C nor in the region bounded by C, so

[tex]\displaystyle \int_C (3x+4y)\,\mathrm dx + (2x-3y)\,\mathrm dy = \iint_D\frac{\partial(2x-3y)}{\partial x}-\frac{\partial(3x+4y)}{\partial y}\,\mathrm dx\,\mathrm dy = -2\iint_D\mathrm dx\,\mathrm dy[/tex]

where D is the interior of C, i.e. the disk with radius 2 centered at the origin. But this integral is simply -2 times the area of the disk, so we get the same result: [tex]-2\times \pi\times2^2 = -8\pi[/tex].

Answer:

use phythagoras formula of calculating right angles

a^2=b^2+c^2

42^2=b^2+78^2 (substitution + transposement)

b^2=72^2-42^2

b^2=3420 (introduce a square root both sides)

what you do on the left .you also do it on the right

b is the unknown side of the triangle

b=58.48 inched

The lengths of the legs of the right angle triangle is 30 inches and 72 inches.

A triangle is a closed plane figure formed by joining three noncolinear points.

We know Pythagoras's theorem which states the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

Given one leg of a right-angle triangle is 42 inches longer than the other leg.

Assuming the smallest leg to be x inches.

∴ The other leg is (x + 42) inches also given hypotenuse is 78 inches.

∴ (x + 42)² + x² = 78².

x² + 84x + 1764 + x² = 6084.

2x² + 84x - 4320 = 0.

x² + 42x - 2160 = 0.

As length can not be negative value of x = 30 inches.

∴ The smaller leg is 30 inches and the larger leg is (30 + 42) = 72 inches.
