Answer:

Center: (0,0)

Radius: [tex]r=\sqrt{10}[/tex]

Step-by-step explanation:

The given circle has equation

[tex]10x^2+10y^2=100[/tex]

In order to complete the square, we must make sure the coefficient of the quadratic terms are unity.

We divide through by 10 to obtain;

[tex]x^2+y^2=10[/tex]

The coefficient of the linear terms of both variables are zero.

Therefore the equation can be rewritten as;

[tex](x-0)^2+(y-0)^2=10[/tex]

Comparing to [tex](x-h)^2+(y-k)^2=r^2[/tex]

We have (h,k)=(0,0) to the center of the circle and [tex]r=\sqrt{10}[/tex] to be the radius of the circle.

Answer:

Equation: x²  + y² = 10

center = (0, 0)

  radius = √10

Step-by-step explanation:

The general equation of a circle is ;

(x - a)²  + (y - b)² = r²

Where (a, b) is the coordinate of the center of the circle, and r is its radius.

Where the center is (0,0), the equation becomes,

x²  + y² = r²

In our case we have;

10x² + 10y² = 100

dividing both side by ten,

x²  + y² = 10

∴ center = (0, 0)

  radius = √10

Formula

i = prt

Givens

P = 500

i = 25

r = 5% = 5/100

t = ?

Solution

25 = 500 * 5/100 * t       Cancel out 100 on the right

25 = 5*5*t                        Combine the right

25 = 25 * t                       Divide by 25

Answer:   " 1 year . "

_________________________________________________

Step-by-step explanation:

_________________________________________________

Use the formula/equation:

        I = Prt ;   that is;  " I = P × r × t "  ;

in which:  

" Interest (in dollars) =

     Principal amount ("P" ; in dollars) * r ["rate"]   *  time ("t", in years) ]  ;

Note: the rate, "r" ; refers to the interest rate.

We wish to solve for the "time, "t" .

_________________________________________________

 I = Prt ;

_________________________________________________

Let us isolate "t" one one side of the equation;

    by rearranging the formula;

We know:  I = Prt   ;

Divide each side of the equation by "Pr" :

I/ (Pr) = [ (Prt) / (Pr) ]  ;

to get:

I / (Pr) = t ;

↔  t = I (P * r ) ;

Now, plug in our given values, and solve for "t" ; time, in years.

Given:  P = 500 (dollars) ;

            I  = 25 (dollars) ;  

           r = 5% ;  Note, for the purposes of this formula; we write this as a "decimal" ;

           r = 5% = 5/100 = 0.05 ;

_________________________________________________

 t  =  I / (P * r)  ;

t = 25  / (500 * 0.05) ;

t =  25 / (25) ;

t = 1  yrs.

Step-by-step explanation:

Given equation is [tex]f(x)= x(x+1)^2 (2x-3)(x+2)^2[/tex].

Now we need to find about what is the degree of the give function.

We know that degree of polynomial function is the highest exponent of the variable (x).

So we can either expand the whole equation or count the degree of each factor then add those to get the degree of the given function.

Second choice will be easier.

Degree of [tex]x[/tex] = 1

Degree of [tex](x+1)^2[/tex] = 2

Degree of [tex](2x-3)[/tex] = 1

Degree of [tex](x+2)^2[/tex] = 2

Hence degree of the given polynomial function = 1+2+1+2=6

Martha walked for 0.67 hours.

Here's how we can calculate it:

Total time spent hiking:

12:30 AM - 11:30 PM = 1 hour (since 12:30 AM is midnight and the same as 00:30 AM)

Convert hours to minutes: 1 hour * 60 minutes/hour = 60 minutes

Time spent running:

Subtract the walking time from the total time: 60 minutes - 20 minutes = 40 minutes

Convert running time to hours:

Divide minutes by minutes per hour: 40 minutes / 60 minutes/hour = 0.67 hours

Therefore, Martha walked for 0.67 hours.

Question

If Martha went on a hiking trip at 11:30 PM, and walked for 20 minutes, and ran the rest, and came back at 12:30 AM, how many hours did Martha WALK?

Step-by-step explanation:

The surface area of the rectangular prism is the sum of all the 6 faces.

Area = 2 (3*3.4) = 20.4

Area = 2 (3*4.1) = 24.6

Area = 2 (3.4*4.1) = 27.88

Thus, Surface Area = 20.4 + 24.6 + 27.88 = 72.88 ft ^2

Answer:

The correct answer option is D. 72.88 ft^2.

Step-by-step explanation:

Answer:

23°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

3x + 1 +2x - 3 + 9x = 180 ( simplify left side )

14x - 2 = 180 ( add 2 to both sides )

14x = 182 ( divide both sides by 14 )

x = 13

The 3 angles are

3x + 1 = (3 × 13) + 1 = 39 + 1 = 40°

2x - 3 = (2 × 13) - 3 = 26 - 3 = 23° ← smallest angle

9x = 9 × 13 = 117°

Answer: OPTION B

Step-by-step explanation:

 Use the following formula:

[tex]SA=\frac{pl}{2}+B[/tex]

Where p is the perimeter of the base, l is the slant height and B is the area of the base.

The perimeter is:

[tex]p=6*s=6*3m=18m[/tex]

Where s is the lenght of a side.

The slant height is given:

[tex]l=6,2m[/tex]

The area of the base is:

[tex]B=\frac{3\sqrt{3}s^2}{2}=\frac{3\sqrt{3}(3m)^2}{2}=23.382m^2[/tex]

Where s is the length of a side.

Substitute values. Then, the result is:

[tex]SA=\frac{(18m)(6.2m)}{2}+23.382m^2=79.18m^2[/tex]

Answer:

The correct answer option is B. 79.18 m^2.

Step-by-step explanation:

We are given a diagram of a regular hexagonal pyramid with height 5.6 m, slant height 6.2 m and base edge length 3m.

We know that the surface area of a regular hexagonal pyramid is given by:

[tex]\frac{PI}{2} +B[/tex]

where P = perimeter of the base, I = slant height and B = base area.

Perimeter of base = [tex]3 \times 6[/tex] = 18 m^2

Base area (area of hexagon) = [tex]\frac{3\sqrt{3} }{2} a^2[/tex] =  [tex]\frac{3\sqrt{3} }{2} 3^2[/tex] = 23.38 m^2

Surface area of hexagonal pyramid = [tex]\frac{18 \times 6.2}{2} +23.38[/tex] = 79.18 m^2

Answer:

b

Step-by-step explanation:

well, in the election, the losing candidate received 10200 votes, and we know that's 30% of the whole votes cast, le's say the whole amount is "x" or namely 100%.

B)

[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 10200&30\\ x&100 \end{array}\implies \cfrac{10200}{x}=\cfrac{30}{100}\implies \cfrac{10200}{x}=\cfrac{3}{10} \\\\\\ 102000=3x\implies \cfrac{102000}{3}=x\implies 34000=x[/tex]

A)

Dorian's 3060 is really 30% of 10200, however, the losing candidate received 30% of the total votes cast, and that is 10200, so Dorian mistakenly is using 30% of the 30% received by the losing candidate as point of reference for her total.

Final answer:

Dorian's claim is incorrect because dividing 10,200 votes by 30% (or 0.30) gives 34,000 votes, which is the correct total number of votes cast in the mayoral election. Therefore, the calculation shows that the total votes are much higher than Dorian's claim of 3,060 votes.

Explanation:

A. Dorian's claim that the total number of votes cast in the mayoral election was 3,060 is not reasonable because if the losing candidate received 10,200 votes which represented 30%, then the total votes should be much higher than 3,060. To find the total, you would divide the number of votes the candidate received by the percentage they represent.

B. To find the total number of votes cast in the mayoral election, you would set up the equation 10,200 = 0.30 * Total Votes. Dividing 10,200 by 0.30 gives the total number of votes cast, which is 34,000.

Equation: Total Votes = 10,200 votes / 0.30 = 34,000 votes

The equation x + y = 10 represents a linear relationship that spans all real numbers in both x and y directions. Thus, the domain and the range for this function are both all real numbers.

The equation for the set F is x + y = 10, which is a straight line on a graph. This line extends infinitely in both directions, meaning that there is no restriction on the possible values of x (the domain) and y (the range). Therefore, the correct answer for both domain and range would be 'All Real Numbers'.

To visualize this, imagine you plug in any number for x and solve the equation for y. Similarly, you can do the same, guessing a y-value and solving for x. No matter the number chosen, there will always be a corresponding number on the other side, whether positive, negative, or zero.

Remember that a domain is the set of all inputs (or 'x' values) that a function can accept, and a range is the set of all possible outputs (or 'y' values) that the function can produce. In this example, the function can handle and generate all real numbers, so its domain and range are all real numbers.

The difference is [tex]\( \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \)[/tex].

To subtract the two rational expressions [tex]\( \frac{5x}{x^2-x-6} \) and \( \frac{4}{x^2+4x+4} \)[/tex], we need to find a common denominator.

First, factor the denominators:

1. x²-x-6 = (x-3)(x+2)

2. x²+4x+4 = (x+2)²

The common denominator will be (x-3)(x+2)(x+2).

Now, rewrite the expressions with the common denominator:

1. [tex]\( \frac{5x}{(x-3)(x+2)} \)[/tex]

2. [tex]\( \frac{4}{(x+2)^2} \)[/tex]

To subtract, the numerators remain the same, so the expression becomes:

[tex]\[ \frac{5x}{(x-3)(x+2)} - \frac{4}{(x+2)^2} \][/tex]

To combine the fractions, we need to rewrite the first fraction with the common denominator:

[tex]\[ \frac{5x(x+2)}{(x-3)(x+2)(x+2)} - \frac{4(x-3)}{(x-3)(x+2)(x+2)} \][/tex]

Now, we can subtract the fractions:

[tex]\[ \frac{5x(x+2) - 4(x-3)}{(x-3)(x+2)(x+2)} \\\[ = \frac{5x^2 + 10x - 4x + 12}{(x-3)(x+2)(x+2)} \\\[ = \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \][/tex]

So, the difference is [tex]\( \frac{5x^2 + 6x + 12}{(x-3)(x+2)(x+2)} \)[/tex].

To find the difference between the two rational expressions, we first need to factorize the denominators and simplify where possible. Let's break it down step by step:

1. Factorize the denominators:

[tex]\(x^2 - x - 6 = (x - 3)(x + 2)\) \(x^2 + 4x + 4 = (x + 2)^2\)[/tex]

2. We rewrite the expressions with common denominators:

  [tex]\(\frac{5x}{(x - 3)(x + 2)} - \frac{4}{(x + 2)^2}\)[/tex]

3.  To simplify these, we need a common denominator, The least common denominator is [tex]\((x - 3)(x + 2)^2\).[/tex], so to get it, we multiply (x + 2) with Expression 1 and  (x - 3) with Expression 2 on both numerator and denominator. We get:

  [tex]\(\frac{5x(x + 2)}{(x - 3)(x + 2)^2} - \frac{4(x - 3)}{(x - 3)(x + 2)^2}\)[/tex]

4. We combine the fractions:

[tex]\(\frac{5x(x + 2) - 4(x - 3)}{(x - 3)(x + 2)^2}\)[/tex]

  [tex]\(= \frac{5x^2 + 10x - 4x + 12}{(x - 3)(x + 2)^2}\) \(= \frac{5x^2 + 6x + 12}{(x - 3)(x + 2)^2}\)[/tex]

So, the difference between the two rational expressions is [tex]\(\frac{5x^2 + 6x + 12}{(x - 3)(x + 2)^2}\).[/tex]

Answer:

so A = 45degrees because tan^-1(1) = 45 and c = 30 because the half triangle is a 30-60-90 triangle so d = 105

Since its a 30-60-90 triangle and you know that one of the sides is 6, you can now infer that the rest of the sides are 8, and 10.

Also using the 6 side you can use a 3-4-5 triangle by dividing 6 by 4 wich equals 1.5 then multiply that by 3 to get the other sides by using Pythagorean therom. so the sides are 10, 7.5 and 12.5 witch gives you the bas and since area = 1/2bh area= 1/2(12.5 times 6)= 37.5
