Answer:

<h3>x =11</h3>

Step-by-step explanation:

Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle

From the diagram

Interior angles = 5x +10 and 58

Interior angle = 11x+2

Equate both expressions

5x + 10 + 58 = 11x+2

5x - 11x = 2 - 10 - 58

-6x = 2-68

-6x = -66

x = -66/-6

x = 11

<em>Hence the value of x is 11</em>

Find the domain of -1/x^2-4

Ipatiy [6.2K]

Answer:

$\mathbb{R}-\{0\}$

$(-\infty,0)\ U\ (0,+\infty)$

Step-by-step explanation:

<u>The domain of a Function</u>

Given a real function f(x), the domain of f is made of all the values x can take, such that f exists. The function given in the question is

$\displaystyle f(x)=-\frac{1}{x^2}-4$

Finding the domain of a function is not possible by giving x every possible value and check if f exists in all of them. It's better to find the values where f does NOT exist and exclude those values from the real numbers.

Since f is a rational function, we know the denominator cannot be 0 because the division by 0 is not defined, so we use the denominator to find the values of x to exclude from the domain.

We set

$x^2=0$

Or equivalently

x=0

The domain of f can be written as

$\mathbb{R}-\{0\}$

Or also

$(-\infty,0)\ U\ (0,+\infty)$

In 1989 a locally-owned car company sold 2,881 cars.

Rufina [12.5K]

D. <u>103 12/13</u> or about <u>104</u>

First sort the data into two sets of points, (1989,2881), (2002, 4232).

Now use the slope equation with your numbers.

(y2-y1)/(x2-x1)

(4232-2881)/(2002-1989)

1351/13=

Answer:

The similar triangles are $\triangle BPE$ and $\triangle BCG$

$BE = 321$ and $PE =286$

Step-by-step explanation:

Given

See attachment for the required figure

Solving (a): The similar triangles

The similar triangles are $\triangle BPE$ and $\triangle BCG$

Solving (b): Why they are similar

Both triangles are similar because $\triangle BCG$ is dilated (i.e. enlarged) and then reflected to give $\triangle BPE$ .

Solving (c): Calculate BE and PE

The following are equivalent ratios

$BP: BC = BE : BG$

and

$BP: BC = PE : CG$

Solving for BE, we have:

$BP: BC = BE : BG$

Substitute the known values

$250:350 = BE:450$

Express as fraction

$\frac{250}{350} = \frac{BE}{450}$

Multiply both sides by 450

$450 * \frac{250}{350} = BE$

$321 = BE$

$BE = 321$ -- approximated

Solving for PE, we have:

$BP: BC = PE : CG$

Substitute known values

$250:350 = PE:400$

Express as fraction

$\frac{250}{350} = \frac{PE}{400}$

Multiply both sides by 400

$400 * \frac{250}{350} = PE$

$286 = PE$

$PE =286$

An arithmetic sequence is described by the function f(n) = -3n + 7.

Maru [420]

Answer:

the first five terms are: 4, 1, -2, -5, -8

Step-by-step explanation:

To find the first five terms, you simply input the numbers (1-5) into the equation.

$-3(1)+7=4$

$-3(2)+7= 1$

$-3(3)+7=-2$

$-3(4)+7=-5$

$-3(5)+7=-8$
