Answer:

The circle's centre is at the position (3, 5), and it has a radius of 2

Step-by-step explanation:

First let's put it in a useful format by completing the squares:

x² + y² - 6x - 10y + 30 = 0

x² - 6x + y² - 10y = -30

x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25

(x - 3)² + (y - 5)² = 4

This tells us that the centre position is (3, 5) and the radius is √4, or 2

The coordinates of the center will be - O(3, 5) and the radius will be - 2 units

We have the following equation of a circle -

[tex]x^{2} +y^{2} -6x-10y+30=0[/tex]

We have to find the radius and center coordinates of this circle.

A Circle is a curve traced out by a point that moves in a plane such that its distance from a given point is constant.

According to the question, we have the equation of circle -

[tex]x^{2} +y^{2} -6x-10y+30=0[/tex]

[tex]x^{2} +y^{2} -6x-10y=-30\\x^{2} -6x +y^{2} -10y = -30\\x^{2} -6x +(\frac{-6}{2} )^{2} +y^{2} -10y +(\frac{-10}{2} )^{2} = -30+(\frac{-6}{2} )^{2} +(\frac{-10}{2} )^{2}\\\\x^{2}-6x +9+y^{2} -10y+25 = -30 +9+25\\(x-3)^{2} + (y-5)^{2} =4[/tex]

Compare the above equation with the general equation of circle -

[tex](x-a)^{2} +(y-b)^{2} =r^{2}[/tex]

We get -

the coordinates of center will be - O(3, 5) and the radius will be = [tex]\sqrt{4}[/tex] = 2 units.

Hence, the coordinates of the center will be - O(3, 5) and the radius will be - 2 units

The amount to tax that the executive pays is 87,500 GBP.

Tax is a compulsory payment that is levied on the income or one the sales of certain goods and services. Tax is imposed by the government to achieve various macroeconomic objectives. Taxes reduces the income of an individual.

When tax is levied on the income of an individual, it is known as an income tax. There are various types of taxes, one of them includes progressive tax. Progressive tax levies a higher tax percentage on those that earn an higher amount of money. Thus, the tax rate increases as income increases.

The executive earns 175,000 GBP gross. 175,000 GBP is greater than 150,000 GBP, thus, he would be taxed at a rate of 50%. In order to determine the tax the executive would pay, multiply the income of the executive by the tax rate.

Multiplication is the mathematical operation that is used to calculate the product of two or more numbers. The sign that is used to represent multiplication is x.

Tax that would be paid = tax rate x gross income

175,000 x 0.5 =87,500 GBP

Answer:

Yes.  We can conclude that the percentage of the employed workers (p1), who have registered to vote, exceeds the percentage of unemployed workers (p2), who have registered to vote.

Step-by-step explanation:

Number of employed persons in the sample = 700

Number of unemployed person in the sample = 300

Number of employed persons who have registered to vote (p1) = 500

Number of unemployed persons who have registered to vote (p2) = 200

Proportion of registered voters who are employed = 500/700 = 71.4%

Proportion of registered voters who are unemployed = 200/700 = 28.6%

This implies that the percentage of registered voters who are employed is more than the percentage of registered voters who are employed.  71.4% (500/700) of the employed registered to vote as against 66.7% (200/300) of the unemployed who registered to vote.

We can conclude that of the 700 registered voters in the sample, 71.4% (500/700) are employed while 28.6% (200/700) are unemployed.

Therefore, the percentage of the employed workers (p1), who have registered to vote, exceeds the percentage of unemployed workers (p2), who have registered to vote.

Answer:

y = -6x + 6

Step-by-step explanation:

Unless you are asking for solving the linear equation itself, the answer would be y = -6x + 6.

If you were trying to set up systems and then solve for actual solutions, you would need two equations. I will go with solving the linear equation, but if you meant solving systems, the answer cannot be found.

Step-by-step explanation:

Abba grew 1 foot over the past year. He is now 5 feet tall. What was Abba's percent increase in height?

Step one:

given data

We are told that Abba grew 1 foot in the past year, and now he is 5 feet tall, this means that his previous height is 4 feet.

Step two:

We want to find the percent increase

%increase = change in height/ previous height *100

%increase =5-4/4*100

%increase = 1/41*100

%increase =0.25*100

%increase = 25%

Answer:

He grew 1/5 = 20%

he was 4/5 = 80%

now he is 5/5 = 100%

u as the subject of the given formula is, [tex]u = \sqrt{v^{2}-2as }[/tex]

Step-by-step explanation:

Given;

v² = u²+2as

To make u the subject of the formula, the following steps are taken;

v² = u²+2as

v²  - 2as = u²

take the square - root of both sides of the equation;

[tex]\sqrt{u^{2} } = \sqrt{v^{2}-2as } \\\\u = \sqrt{v^{2}-2as }[/tex]

Thus, u as the subject of the given formula is, [tex]u = \sqrt{v^{2}-2as }[/tex]

Answer:

x=62

Step-by-step explanation:

all angles should add to 180

180-56=124

124÷2=62

Answer:

Step-by-step explanation:

1st notice that two of the sides are the same length?   ( isosceles ) that mean the two angles at the "base" which is the side that both of the same size legs tie into... that's the side that is 4.5 in the picture.  soooo if both of those angles are the same.. and we know that the angles are going to add to 180 then....  we can say    the the 56° is the same as the one at the other end of the 4.5 side (base) so  2*56°=112°

and then 112° + x = 180°

x = 180-112

x = 68°

Answer:

a) 12cm

b) 360cm²

c) 2160cm cubed

Step-by-step explanation:

a)

you would use Pythagoras theorem  for A

so half of 18 is 9

15² - 9² = 144

the square root of 144 is 12

the height is 12cm

b)

18 x 20 = 360cm²

c)

csa x L

csa = b x h divide by 2

18 x 12 = 216cm²/2 = 108cm²

108xm² x 20cm = 2160cm cubed
