Satellites KA-12 and SAL-11 have spotted a UFO. Scientists want to determine its distance from KA-12 so they can later determine its size. The distance between these satellites is 900 km. From KA-12's perspective, the angle between the UFO and SAL-11 is 60∘. From SAL-11's perspective, the angle between the UFO and KA-12 is 75∘. How far is the UFO from KA-12?

Answer:

g = 48

Step-by-step explanation:

60/3 = g-8/2

20 = g-8/2

40 = g-8

g = 48

Answer:

g = 28

Step-by-step explanation:

60 ÷ 3 = g - 8 , that is

20 = g - 8 ( add 8 to both sides )

28 = g

a) The number of ways that she can arrange the 9 paintings is; 362880 ways

b)  If she only wants to display 5 of the paintings, the number of ways can she choose the paintings she wishes to display is; 126

c) The number of ways can she arrange 5 out of 9 paintings is; 120

a) If we take 9 paintings to be hung in 9 spaces arranged side by side, then it means that the first space can have any one of the 9 paintings, the second space can have any one of the remaining 8 paintings (as 1 is already hung), the third space can have any one of the remaining 7 paintings (as 2 already hung) e.t.c

Thus;

Number of ways to arrange all the paintings from left to right = 9! = 362880

b) We are now told that she only wants to display 5 of the paintings. Thus;

Number of ways she can choose the paintings she wishes to display is done by the combination formula;

nCr = n!/(r!(n - r)!)

9C5 = 9!/(5!(9 - 5)!)

= 126 ways

c) Any 5 of the 9 paintings can be arranged in;

5! = 120 ways

By solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

In a mathematical equation, the equals sign is used to express that two expressions are equal.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.

For instance, the expressions 3x + 5 and 14 make up the equation 3x + 5 = 14, with the word "equal" separating them.

So, we know that:

Apple and mango are worth $13.50.

Each mango costs $0.75, but each apple costs $1.50.

Let the number of apples be x and the number of mangoes be y, so that:

1.50x + 0.75y = 13.50

Fewer apples than mangoes by six That is to say,

x = y + 6

x - y = 6

The two resulting equations are:

1.50x + 0.75y = 13.50

x - y = 6

The simultaneous equation's solution provides

x = 8

y = 2

Therefore, by solving equations, we know that the number of apples and mangoes purchased is 8 and 2, respectively.

Step-by-step explanation:

Explanation:

Angle R = angle A = 41 since both angles involve a single arc marking.

Angle S = angle B = 74, both involve a double arc

For any triangle, the inside angles always add to 180 degrees.

R+S+T = 180

The value of the angle x will be equal to 36°.

A circle's arc is defined as a portion or segment of its circumference. A chord of a circle is a straight line that can be created by connecting the two ends of an arc. A semicircular arc is one whose length is exactly half that of a circle.

Given that the minor arc is 144. The value of angle x will be calculated by the ratio of the difference between the major arc and the minor arc to the 2.

The angle x will be calculated as,

x = ( Major arc - Minor arc) / 2

x = ( 360-144-144) / 2

x = 72 / 2

The age of Mark, Taylor, & Brian's ages will be Whole numbers 36,37, and 38 respectively.

What exactly is a whole number?

Whole numbers are a collection of positive integers and zero that do not contain any fractions.

                       It is denoted by the letter "W," and its corresponding set of numbers are "0," "1, 2, 3,,","5,,"6,,"7,","8,"..."

It is given that Mark, Taylor, & Brian's ages are consecutive whole numbers, Mark is the youngest, and Brian is the oldest and the sum of their ages is 111.

Suppose the age of mark is x as a result the age of Taylor and brian will be x + 1 and x + 2 respectively.

From the given condition the sum of their ages is 111,

⇒x + x + 1 + x + 2 = 111

⇒3x + 3 = 111

⇒3x = 111 - 3

⇒3x = 108

⇒x = 108/3

⇒x = 36

When we reject the null hypothesis and the null hypothesis is true, we have made a Type I error.

In statistical hypothesis testing, the null hypothesis is a statement that represents the anticipated or "normal" outcome of a specific experiment. Unless there is evidence to the contrary, the null hypothesis, which is generally represented by the symbol "H0," is taken to be true.

A Type I mistake, sometimes known as a "false positive," arises when the null hypothesis is correct but is rejected based on the evidence. Applying a statistical test with a strong significance level increases the likelihood of rejecting the null hypothesis even when it is correct, which frequently leads to this mistake.

Making a Type I error can have major repercussions since it can result in judgments being formed based on flawed information and wrong inferences being drawn.

Create a square on paper by using a pencil. Tw dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

According to our question-

V' equals (4 pi x r' x r'2) (4 pi x (.9 3) x r2 x r')

This equation expresses how quickly the rind volume changes over time.

As stated in the issue, r' = 2.

Answer:

y = [tex]x^2+2x+12[/tex] (x and y intercepts under "Step-by-step explanation" section)

Step-by-step explanation:

We can start by finding the vertex form and then expand it to the standard form.

The vertex form of the quadratic equation is

[tex]y=a(x-h)^2+k[/tex], where a is a constant and (h, k) is the vertex.

By plugging in 1 for a, -1 for h, and 11 for k, we have:

[tex]y=1(x-(-1))^2+11\\y=(x+1)^2+11[/tex]

Now we simply expand this vertex form to get the standard form:

[tex]y = (x+1)^2+11\\y=(x+1)(x+1)+11\\y=x^2+x+x+1+11\\y=x^2+2x+12[/tex]

We can find the x and y-intercepts using the vertex form.

To find the x-intercept, we plug in 0 for y:

[tex]0=(x+1)^2+11\\-11=(x+1)^2\\\sqrt{-11}=x+1;-\sqrt{11}=x+1\\ x_{intercepts}:(-1+\sqrt{-11}, 0); (-1-\sqrt{-11})[/tex]

The x-intercepts are non-real answers, so the quadratic equation never intersects the x-axis.

To find the y-intercept, we plug in 0 for x:

[tex]y=(0+1)^2+11\\y=1^2+11\\y_{intercept} =(0,12)[/tex]
