Answer:

  18 units

Step-by-step explanation:

The distance formula is used to find the distance between two points:

  d = √((x2 -x1)² +(y2 -y1)²)

For AB, the distance is ...

  d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5

The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.

6. 24

7. 0

8. 46

9. -1

10. 42

11. -4

13. 30

14. -5

When an equation says something like 23 - (-23) then you actually add them together because you multiply the inside by -1 to get 23 + 23

Answer:

25.12

Step-by-step explanation:

Circumference (C) = 2πr

Where r = radius

We want to find the circumference of a circle with a radius of 4m ( this means that r = 4 )

To do so we simply plug in the value of r into the circumference formula

Formula: C = 2πr

r = 4 ( note that it says use 3.14 for π )

plug in values

C = 2(3.14)(4)

Simplify

C = 25.12

Answer:

b = -2

Step-by-step explanation:

[tex] - 2b - ( - 7) = 11[/tex]

[tex] - 2b + 7 = 11[/tex]

[tex] - 2b + 7 - 7 = 11 - 7[/tex]

Answer:

x = 5.5 inches.

Step-by-step explanation:

The perimeter is the sum of the 3 sides, so:-

x + x + 3 + 2x + 5 = 30

4x + 8 = 30

4x = 22

x = 5.5.

Answer:

13,236 minor earthquakes occurred

Step-by-step explanation:

[tex]\frac{Part}{Total}[/tex]

"x" part amount of earthquakes

14,905 total amount of earthquakes

88.8 % part percentage of earthquakes

100% total percentage of earthquakes

[tex]\frac{x}{14905}[/tex] = [tex]\frac{88.8}{100}[/tex]

x = 14,905 × [tex]\frac{88.8}{100}[/tex]

Answer:

  264x³-66x

Step-by-step explanation:

The order of operations requires this be evaluated as ...

  11x(96x÷4x -6) . . . . given

  11x(24x·x -6) . . . . . . division inside parentheses

  11x(24x² -6) . . . . . . multiplication inside parentheses

  264x³ -66x . . . . . multiply by outside factor (use the distributive property)

_____

Additional comment

The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...

  ((96x)÷4)x = 24x²

You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...

  (for x=2) 11×2×(96×2÷4×2-6)

it should give you the result 1980, not 396.

Answer:

= 198x

Step-by-step explanation:

11x × { 96x ÷ 4x -6}

11x × { 24x -6}

264x - 66x

= 198x

Answer:

W = 24cm

Step-by-step explanation:

p of a rectangle = 92

L = 22cm and W = ?

p = 2(L+W)

92 = 2(22+W)

92 = 44 + 2W

2W = 92 - 44

2W = 48

W = 48/2

W = 24cm

9514 1404 393

Answer:

Step-by-step explanation:

Consider a zero at x=1.

If it has multiplicity 1, the corresponding factor is (x -1). Now consider the sign of that factor for x = 1.1. The value is (1.1 -1) = 0.1, a positive number.

When the value of x is 0.9, the factor is (0.9 -1) = -0.1, a negative number.

This tells you that values to the left of a zero make the factor(s) associated with that zero be negative. For x-values to the right of the zero, the factor(s) will be positive.

If the multiplicity is even, the product of those factors is positive on either side of the zero. (A negative number to an even power is a positive number.) That is, the graph will not change sign from one side of an even-multiplicity factor to the other. At an odd-multiplicity factor, the graph changes sign.

__

For the problem at hand, the only even-multiplicity factor is (x -1), so the graph will not change sign at x=1. It will touch the axis (be tangent to the x-axis), but will not cross. The other zeros have odd multiplicity (1 or 3), so the graph will change sign there.

It is worthwhile to note that the higher the multiplicity, the "flatter" the graph is at the zero. You can see this in the attachment by comparing the shape of the graph at x=6 with the shape at x=2 (also an upward zero crossing).

_____

Additional comment

You may wonder why the curve is below the x-axis at x=1 when the product of the factors in that neighborhood is always positive. The reason is that there are an odd number of zeros to the right of x=1, so the product of those factors is negative.

Answer:

105 hours

Step-by-step explanation:

first you do 12 times 8 which equals to 96 then you add 9 to it which equals 105 hours

12 days x 8 hours = 96 hours

96 hours + 9 additional hours = 105.

(12x8)+9 = 105

Answer: Choice B

[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]

===============================================================

Explanation:

Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is

c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)

This represents the length of the vector <-4,7>

Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.

The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

AAS (Angle Angle Side) shows congruence.
