James defines a circle as the set of all the points equidistant from a given point. His statement is not precise enough because he should specify that.

Answers

A circle has a center, radius, diameter and points in a plane. Depending on the context, the definition of a circle must contain at least one of the following terms:

Center

Radius

Diameter

Points in a plane

The complete question is as follows:-

James defines a circle as "the set of all the points equidistant from a given point." His statement is not precise enough

because he should specify that

A circle includes its diameter

The set of points is in a plane

A circle includes its radius

The set of points is collinear

What is a circle?

A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.

Based on James' definition of a circle, he needed to specify that the points are in a plane (option c).

As presented in his definition "the set of all the points" can be interpreted in several ways. Some of which are:

the set of points on a line

the set of points in a plane

the set of points in a region

Etc

Of these numerous possible interpretations, James should have specified that the set of points is in a plane

Answers

Since the paper representing her desk is 1 1/4 inches by 2 1/4 inches, the actual dimensions of her desk are D: 2 ¹/₂ ft by 4 ¹/₂ ft

To answer the question, we need to know what scale is

What is a scale?

A scale is the ratio of two dimension and it is given on a scale drawing.

Given that Chelsea makes a scale drawing of the room and cuts out pieces of paper to represent her furniture, and the paper representing her desk is 1 1/4 inches by 2 1/4 inches.

Since on the scale, we have 1/2 in = 1 foot ⇒ 1 in = 2 ft

Actual dimensions of desk

So, the actual dimensions of her desk are

1 ¹/₄ in by 2 ¹/₄ in = 5/4 in by 9/4 in

= 5/4 × 1 in by 9/4 × 1 in

= 5/4 × 2 ft by 9/4 × 2 ft

= 5/2 ft by 9/2 ft

= 2 ¹/₂ ft by 4 ¹/₂ ft

So, the actual dimensions of her desk are D: 2 ¹/₂ ft by 4 ¹/₂ ft

y=4(3)^x complete a table showing y values for values of x from 0 to 5

To solve this problem, we just have to substitute the values into the exponential equations and solve.

Exponential Equation

In the given exponential equation, we simply need to plug in the values of x from 0 to 5

[tex]y = 4(3)^x[/tex]

when x = 0

[tex]y = 4(3)^x\\y = 4(3)^0\\y = 4[/tex]

when x = 1

[tex]y = 4(3)^x\\y = 4(3)^1\\y = 12\\[/tex]

when x = 2

[tex]y = 4(3)^2\\y = 36[/tex]

when x = 3

[tex]y = 4(3)^3\\y = 108[/tex]

when x = 4

[tex]y = 4(3)^4\\y = 324[/tex]

when x = 5

[tex]y = 4(3)^5\\y = 972[/tex]

From the calculations above, the value of y when x is from 0 to 5 are

x = (N - 3)/2

The probability that she will take a black pen followed by a red pen is;

Write an equation of the parabola in vertex form that passes through ( 3 , -2 ) and has a vertex of ( 5,8 )

Answers

Answer:

Parabola in vertex form: y = a(x - h)2 + k

Vertex: (h, k) = (3, 2) and (x, y) = (13, 8)

y = a(x - h)2 + k

y = a(x - 3)2 + 2 <== with substitution (h, k) = (3, 2)

8 = a(13 - 3)2 + 2 <== with substitution (x, y) = (13, 8)

8 = a(10)2 + 2

100a = 8 - 2 ==> 100a = 6 ==> a = 6/100 ==> a = 3/50

Parabola in vertex form: y = a(x - h)2 + k

y = (3/50)(x - 3)2 + 2  (Final Answer - Parabola in vertex form)

Step-by-step explanation:

Answer:

Hi,

Step-by-step explanation:

Parabola has the equation:

y=k*(x-5)²+8

if x=3, y=-2: -2=k*(-2)²+8 ==> 4k=-10==> k=-5/2

So y=-5/2(x-5)²+8

(3+13-10)+14÷2+4 how do you solve this ?

Answers

Answer: 17

Step-by-step explanation:

Don't forget about PEMDAS. (parentheses, exponents, multiplication, division, addition, subtraction)

Start with parentheses

(3+13-10)... 13+3= 16, 16-10=6 ...

so (3+13-10)=6

Now we have...

6 + 14 / 2 + 4

No exponents so we go on.

no multiplication so we go on

Now division...

14 / 2 = 7 because 7 x 2 = 14

Now we have...

6 + 7 + 4

now we do addition, addition is commutative so you can add it in any order you want

6 + 7 = 13, 13 + 4 = 17

therefore, the answer is 17

8^x = 64^-1

2^3(x) = 2^6(-1)

3x = -6

x = -6/3
