What is the solution to 1/2 |x| = -3?

Two or more figures are said to be similar when they have common properties. The value of MP is 18 units.

More than one figure are said to be similar if they have some relatable common properties, either considering their length of sides or measure of their internal angles. But similarity is not the same as congruence.

In the given question, it can be deduced that ΔMNP is similar to ΔQRP. Thus, relating the corresponding sides of the two triangles we have;

[tex]\frac{12}{30}[/tex] = [tex]\frac{5x-2}{11x+1}[/tex]

cross multiply to have

30(5x-2) = 12(11x+1)

150x - 60 = 132x + 12

collect like terms

150x - 132x = 12 + 60

18x = 72

x = 4

So that,

MP = 5x - 2

      = 5(4) - 2

      = 20 -2

MP = 18 units

Answer:

[tex]y = \frac{1}{10}x[/tex]

Step-by-step explanation:

⭐ What is slope-intercept form?

First, we need to find the value of "m" using the slope formula.

⭐ What is the slope formula?

Substitute the two coordinates you are given into the slope formula.

[tex]m = \frac{1-2}{10-20}[/tex]

[tex]m = \frac{-1}{-10}[/tex]

[tex]m = \frac{1}{10}[/tex]

Substitute the value of "m" into the slope-intercept form equation.

[tex]y = \frac{1}{10}x + b[/tex]

Next, we need to find the value of "b". To do so, substitute a coordinate that you are given into the equation and solve for "b".

I am going to use (10,1), but you can also use (20,2).

[tex]1 = \frac{1}{10} (10) + b[/tex]

[tex]1 = 1 + b[/tex]

[tex]0 = b[/tex]

Substitute the value of "b" into the slope-intercept form equation.

[tex]y = \frac{1}{10}x[/tex]

The polynomial 25x² + 36y²  is the sum of the squares.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, 25x² + 36y² which can be written as,

= 5²x² + 6²y².

= (5x)² + (6y)² it is the sum of the squares, The difference of squares would be (5x)² - (6y)².

The value of ∠JKI is  107⁰.

What is an angle of a triangle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that ∠JKI = (5x−3)⁰, ∠KIJ=(2x+8)⁰, and ∠IJK=(x−1)⁰.

The sum of all angles of a triangle is 180⁰.

(5x−3)⁰ + (2x+8)⁰ + (x−1)⁰ = 180⁰

(5x + 2x + x) + ( - 3 + 8 -1) = 180

8x + 4 = 180

Subtract 4 from both sides:

8x = 176

x = 22

Putting x = 22 in ∠JKI = (5x−3)⁰:

∠JKI = (5×22 − 3)⁰

∠JKI = 107⁰

[tex]\textsf{b)} \quad \dfrac{(y+3)^2}{25}-\dfrac{(x-1)^2}{15}=1[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Standard equation of vertical hyperbola}\\\\$\dfrac{(y-k)^2}{a^2}-\dfrac{(x-h)^2}{b^2}=1$\\\\where:\\\phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $(h, k\pm a)$ are the vertices. \\\phantom{ww}$\bullet$ $(h\pm b, k)$ are the co-vertices. \\\phantom{ww}$\bullet$ $(h, k\pm c)$ are the foci where $c^2=a^2-b^2$.\\\end{minipage}}[/tex]

Given:

As the x-values of the given center, vertex and focus are the same, the hyperbola is vertical (opening up and down).

Given the center is (1, -3):

Use the vertices formula (h, k±a) to find a:

[tex]\begin{aligned} (h, k \pm a) = (1, -3 \pm a) &= (1, 2)\\\implies -3 \pm a &= 2\\a &= 5\end{aligned}[/tex]

Use the foci formula (h, k±c) to find c:

[tex]\begin{aligned} (h, k \pm c) = (1, -3 \pm c)&=(1, -3 \pm 2\sqrt{10})\\c &= 2 \sqrt{10}\end{aligned}[/tex]

Use the found values of a and c with Pythagoras Theorem to find b²:

[tex]\begin{aligned}c^2 &=a^2+b^2\\\implies (2 \sqrt{10})^2&=5^2+b^2\\40&=25+b^2\\b^2&=15\end{aligned}[/tex]

Therefore:

Substitute the found values into the hyperbola formula to create an equation of the hyperbola with the given parameters:

[tex]\dfrac{(y+3)^2}{25}-\dfrac{(x-1)^2}{15}=1[/tex]

Hence, the population increases to [tex]72860102.5[/tex] in the year [tex]2001[/tex] which is nearest to the [tex]8000000000[/tex].

Rate of change (ROC) refers to how quickly something changes over time. It is thus the acceleration or deceleration of changes (i.e., the rate) and not the magnitude of individual changes themselves.

Here given that,

In [tex]2000[/tex], the world population was calculated to be [tex]6,071,675,206[/tex]. The world population increases at a rate of about [tex]1.2[/tex]% annually.

As the population increases [tex]1.2[/tex] % in every year

The expression is x-12.

12 less than a number means subtracting 12 from that number.

So, 12 less than 20 is 8, because is 20−12, 12 less than 12 is 0, because it's 12−12, and so on.

But since the number you need to subtract from is unknown, it's a variable, and you can call it as you like, suppose x. So, using the variable we can write an expression that holds for any number, which always means "take 12 away from my number". If your number is x, the expression would be x-12

This means that the probability of getting exactly 3 heads in ten flips is about 24.1%.

The probability of getting a specific number of heads in a given number of flips follows a binomial distribution, which describes the probability of getting a certain number of successes in a given number of independent trials. The probability of getting a specific number of heads in ten flips can be calculated using the formula:

P(x heads in n flips) = (n choose x) * p^x * (1-p)^(n-x)

where p is the probability of getting a head on each flip and x is the number of heads.

For example, the probability of getting exactly 3 heads in ten flips is:

P(3 heads in 10 flips) = (10 choose 3) * 0.35^3 * (1-0.35)^(10-3) = 0.241

Answer:

The map is displaying 600 miles of land.

Step-by-step explanation:

To find the number of miles of land being displayed on the map, you need to multiply the length of the map in inches by the conversion factor, which is the ratio of inches to miles. In this case, the conversion factor is 2 inches per 200 miles.

So, to find the number of miles of land being displayed on the map, you would do the following calculation: 12 inches * (200 miles / 2 inches) = 600 miles.
