Find the value of x.

1 + 8x

Answer:

The rate of change is -300 meters per minute

Step-by-step explanation:

Here, we want to get the rate of change for the given situation

Firstly, we will need to collate the points

Let us have the points as:

(time, height)

The points are;

(10,4500) and (15,3000)

The formula for the slope m representing the average rate of change is;

m = (y2-y1)/(x2-x1)

m = (3000-4500)/(15-10) = -1500/5 = -300 meters/minutes

Answer: I’m pretty sure it’s y=1/x+5 +2

Step-by-step explanation:

The graph of Function  [tex]y = \frac{1}{x-5}+2[/tex] is same as the graph of [tex]y = \frac{1}{x}[/tex]

"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner."

"Function, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)."

We have

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

The function is shifted 5 units right

⇒[tex]y = \frac{1}{x-5}[/tex]

The function is shifted 2 units up

⇒[tex]y = \frac{1}{x-5}+2[/tex]

Hence, function becomes  [tex]y = \frac{1}{x-5}+2[/tex]

Step-by-step explanation:

2 pi radians = 360 deg

(360 deg)/(2pi rad) = 1

3 pi * (360 deg)/(2 pi rad) = 3 * 180 deg = 540 deg

Answer:

Infinitely many

Step-by-step explanation:

Equation: 5x + 3(x - 1) = 10x - 2x - 3

1) 5x + 3x - 3 = 10x - 2x - 3

2) 8x - 3 = 8x - 3

3)  8x = 8x

4) x = x

Based on this information, it seems that the best answer would be infinitely many solutions.

The ratio is equivalent to 3:18 is 7:42.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Ratio = 3:18

         = 1: 6

1. 6:21

= 3:7

2. 5:20

= 1:4

3. 7:42

= 1:6

4. 12:2

= 6:1

Hence, the ratio is equivalent to 3:18 is 7:42.

Answer:

Acute triangle

Step-by-step explanation:

All of the triangles vertices are under 90 degrees.

For future reference:

Vertex (plural: vertices)= corner

Acute triangle: each vertex <90 degrees

Right triangle: One vertex = 90 degrees

Obtuse triangle: All vertices >90 degrees

Question 1)

The expression:

11 more than one third of a number

Lets split this is up into parts to make it easier

"11", "more", "one third", "of a", "number"

Lets form the expression for each part,

"11" = 11

"more" = +

"one third" = 1/3

"of a" = *

"number" = n

That forms

11 + (1/3) * n or (1/3) * n + 11

Therefore the answer is D) (1/3)n + 11

Question 2)

Equation,

[tex]\frac{6+5*3}{2+1} = 11[/tex]

Left Hand Side

=[tex]\frac{6 + 15}{3}[/tex]                      (multiplication is first then addition)

=[tex]\frac{21}{3}[/tex]

= 7

7  [tex]\neq[/tex] 11

So, Left Hand Side [tex]\neq[/tex] Right Hand Side

Therefore the answer is false

Answer:

AB ≈ 1095 yards

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² + BS² = AS²

AB² + 1300² = 1700²

AB² + 1690000 = 2890000 ( subtract 1690000 from both sides )

AB² = 1200000 ( take the square root of both sides )

AB = [tex]\sqrt{1200000}[/tex] ≈ 1095 yd ( to the nearest yard )

Have a wonderful day!

Answer:

127.5

Step-by-step explanation:

First, we need to find the value of x

since the two angles are connected to a straight line, their sum will be 180 (degrees)

[tex](2x+7)+(6x-9)=180^{o}[/tex]

add the angles together

[tex]\therefore 8x-2=180[/tex]

add 2 to both sides

[tex]\therefore 8x=182[/tex]

divide out by 8

[tex]\therefore x = 22.75[/tex]

now we must determine which angle has the greater value (not visually)

[tex]angle A = 2x+7[/tex]

[tex]\therefore \angle{A} = 2(22.75)+7[/tex]

[tex]\therefore \angle{A} = 45.5+7[/tex]

[tex]\therefore \angle{A} = 52.5[/tex]

[tex]angle B = 6x-9[/tex]

[tex]\therefore \angle{B} = 6(22.75)-9[/tex]

[tex]\therefore \angle{B} = 136.5-9[/tex]

[tex]\therefore \angle{B} = 127.5[/tex]

[tex]\angle{B}>\angle{A}\ \because\ 127.5>52.5[/tex]

so the answer would be 127.5

Answer:

50.27

Step-by-step explanation:

The shape is a circle

Radius is 4

Diameter is 8  (diameter is always double of the radius)

π * r^2 = π * 16 ft^2 = 50.27 ft^2

(16 = 8 * 2)

Answer:

(-3)^2

Step-by-step explanation:

You add 7 on both sides, giving you x^2 - 6x = 7

Then, take half of b, and square it. Giving you x^2 - 6x +(-3)^2 = 7

The answer will be (-3)^2 for this question, but this is not the full solution.

Hope this helped. Good luck on the rest!

Answer:

Step-by-step explanation:

a) Let's [tex]x[/tex] the length of the side of the small square.

Thus,

[tex]x^{2} + (\sqrt{40})^2 = (\sqrt{50})^2[/tex]

[tex]x^{2} + 40 = 50[/tex]

[tex]x^{2} = 50 - 40[/tex]

[tex]x^{2} = 10[/tex]

[tex]x = \sqrt{10}[/tex]

[tex]x=3.16[/tex]

b) Now, the area of the small square is

[tex]A= x^{2}[/tex]

[tex]A=(3.16)^2[/tex]

Answer:

15/2

Step-by-step explanation:

5 3/4 - 1/6x = 4 1/2

move the variable to it's own side.

5 3/4 - 4 1/2 = 1/6x

change the subtracting side to have common denominators

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)

30/4 = x

reduce: 15/2 = x

The value of x should be 15/2.

Since

5 3/4 - 1/6x = 4 1/2

So, it can be like

5 3/4 - 4 1/2 = 1/6x

Now

5 3/4 - 4 2/4 = 1/6x

1 1/4 = 1/6 x

Now we have to divide both sides by 1/6

So,

30/4 = x

x = 15/2
