Answer:

[tex](x-7)^2+(y-2)^2=34[/tex]

Step-by-step explanation:

We want to find the equation of a circle with a center at (7, 2) and a point on the circle at (2, 5).

First, recall that the equation of a circle is given by:

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

Where (h, k) is the center and r is the radius.

Since our center is at (7, 2), h = 7 and k = 2. Substitute:

[tex](x-7)^2+(y-2)^2=r^2[/tex]

Next, the since a point on the circle is (2, 5), y = 5 when x = 2. Substitute:

[tex](2-7)^2+(5-2)^2=r^2[/tex]

Solve for r:

[tex](-5)^2+(3)^2=r^2[/tex]

Simplify. Thus:

[tex]25+9=r^2[/tex]

Finally, add:

[tex]r^2=34[/tex]

We don't need to take the square root of both sides, as we will have the square it again anyways.

Therefore, our equation is:

[tex](x-7)^2+(y-2)^2=34[/tex]

Answer:

Total amount = £500

Step-by-step explanation:

Let the amount for the runner up be = x

Let the amount for winner be =  x + 250

Let the total amount be x + x + 250 = 2x + 250

Ratio of  the amount is 3 : 1

Sum of the ratio = 3 + 1  = 4

Amount for the winner is

                                     [tex]\frac{3}{4} \ of \ (2x + 250) = (x + 250)\\\\\frac{3}{4}\times(2x + 250) = x + 250\\\\\frac{6x}{4} + \frac{750}{4} = x + 250\\\\\frac{6x}{4} - x = 250 - \frac{750}{4}\\\\\frac{6x - 4x}{4} = \frac{1000 - 750}{4}\\\\\frac{2x}{4} = \frac{250}{4} \\\\2x = 250\\\\x = 125[/tex]

Therefore, Amount won by runner - up = x = £125

                       Amount won by winner = x + 250 = 125  + 250 = £375

Therefore, total amount = 375 + 125 = £500

Answer:

3x-8

Step-by-step explanation:

9x²-64  is the same as

(3x)² - 8²

now we have the difference of 2 squares, a²-b² =(a -b)(a +b), where a=3x, b=8

9x²-64 =  (3x-8)(3x+8)

Answer:

ans: x> -9

Step-by-step explanation:

if you multiply

-2x < 18 by -1 than inequality sign changes as

2x > -18

divide both side by 2 to free 2x to x i.e

2x/2 > (-18/2)

so

x> -9

Answer:

no

Step-by-step explanation:

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

longest side = 18, and 18² = 324

11² + 16² = 121 + 256 = 377 ≠ 324

Then triangle is not right.

Answer:

3540

2

Step-by-step explanation:

Total number of members = 60

Number of members to be elected = 2

Since the order of selection matters as the first is president and second is vice president ;

Using the permutation formula :

nPr = n! ÷ (n-r)!

60P2 = 60! ÷ (60 - 2)!

60P2 = 60! ÷ 58!

60P2 = 3540

B.) 2 members A and B will accept to serve only if they are selected to serve together ;

Since only 2 members (president and vice president) are to be chosen ; Hence, only the tow of them (A and B) will be chosen, to do this ;

2P2 = 2! /(2 - 2)! = 2! / 0! = (2*1)/1 = 2

Answer:

29 ft

Step-by-step explanation:

We solve using the Trigonometric function of Tangent

tan θ = h - 5/20

θ = 50°

Hence

tan 50 = h - 5/20 feet

Cross Multiply

tan 50 × 20 feet = h - 5

23.8350718518842 + 5= h

h = 28.8350718518842

h = 29 ft

b

Step-by-step explanation:

Answer:

(a) (0.9240,  0.956)

(b) (0.6383, 0.7017)

Step-by-step explanation:

The number of internet users involved in the survey, n = 846

The percentage of the respondents that said the internet has been good thing for them personally, [tex]\hat p[/tex] = 94%

(a) The confidence interval of a percentage is given as follows;

[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

The z-value for 95% confidence interval = 1.96

We get;

[tex]CI=0.94\pm 1.96\times \sqrt{\dfrac{0.94 \times (1-0.94)}{846}} \approx 0.94 \pm 1.6003 \times 10^{-2}[/tex]

CI = 0.9240 ≤ [tex]\hat p[/tex] ≤ 0.956 = (0.9240,  0.956)

(b) The percentage of the internet users that said the internet has directly strengthened their relationship with their families, [tex]\hat p[/tex] = 67% = 0.67

The 95% confidence interval is therefore;

[tex]CI=0.67\pm 1.96\times \sqrt{\dfrac{0.67 \times (1-0.67)}{846}} \approx 0.67 \pm 3.1686\times 10^{-2}[/tex]

From which we have;

CI = 0.6383 ≤ [tex]\hat p[/tex] ≤ 0.7017 = (0.6383, 0.7017)

Answer:

g(x) = [tex]3x^{4} + 6[/tex]

Step-by-step explanation:

To move a function up or down along the y-axis all you would have to do is add or subtract the numbers of units that you want the graph to move up or down. Adding a value to the entire function moves it up, while subtracting moves it down. Therefore, in order to move f(x) up 6 units we simply add 6 to the function. Therefore, g(x) will be the following

g(x) = [tex]3x^{4} + 6[/tex]

Both f(x) and g(x) can be seen in the attached picture below
