Answer:

44cm

Step-by-step explanation:

Since, diameter d=14cm

C=πd= 22/7 ×14= 44cm

The equation of the given circle with points  P(-10,10) and Q(6,-2) gives the diameter of a circle will be (x-2)² +(y-4)² = 100.

A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.

In our daily life, we always see circle objects for example our bike wheel.

The longest line which can be drawn inside the circle will be the diameter.

Area of circle = πr²  and the perimeter of circle = 2πr where r is the radius of the circle.

Given that diameter of the circle is bounded by points P(-10,10) and Q(6,-2).

Centre coordinate = midpoint of P(-10,10) and Q(6,-2).

Midpoint of P(-10,10) and Q(6,-2)  

[(-10 + 6)/2 , (10-2)/2 ] = (-2,4 )

Diameter of circle = length between P(-10,10) and Q(6,-2).

lenth between P(-10,10) and Q(6,-2) = 10 units can be calculated by length formula.

The equation of a circle with a center (-2,4 ) and diameter of 10 is given by

(x-2)² +(y-4)² = 10² hence it will be correct.

Answer: As a fraction it is 1/5 but as a percent 20%

Step-by-step explanation:

this is because 12/60=1/5 or 20%

answer is 20%

heres why

ok so if there is 60 balls all together out of all the color and you want to get a blue ball but the blue has less balls out of all the other colored balls so there is would be a less percent of getting a ball of that color out of 100%

you would need to take the blue color of balls and put in a fraction with the amount of balls together

so that would be 12/60

you half 12/60 and you would need to get the percent which is 20% so you have a 20% of getting a blue colored ball

Answer:

[tex]x=\frac{5}{2}[/tex]     or     x= -4

Step-by-step explanation:

To solve the quadratic equation, start by factorizing it.

[tex]2x^{2} +3x-20=0[/tex]

(2x -5)(x +4)= 0

Since the equation equals to zero, either one of its factor, i.e. (2x -5) or (x +4), can be equal to zero.

2x -5= 0     or     x +4= 0

Solve for x:

2x= 5         or           x= -4

[tex]\bf{x=\frac{5}{2}}[/tex]

_______

Alternatively, the quadratic formula can be used to solve the equation.

[tex]\boxed{x=\frac{-b\pm\sqrt{b^{2}-4ac } }{2a} }[/tex]

This is especially useful when the quadratic equation cannot be factorized. To use the formula, ensure that the equation is in the form of [tex]ax^{2} +bx +c=0[/tex].

Answer:

(5,4)

Step-by-step explanation:

What is the solution of two function?

The solution of a system of equations is simply where the value of x ( input ) creates an output ( y value ) equal to each other regarding the two functions.

How do identify the solution via graph.

We can identify the solution of a system of equations via graph by looking at where the two functions intersect.

Identifying the solution.

Looking at the graph, the two lines intersect at (5,4)

The answer choices are asking for the value of x of the solution which would be 5 as x = 5 in (5,4)

The rule is

If two lines are graphed then their solution is their intersection point .

Here both f(x) and g(x) are intersecting at

So (5,4) is solution

Option C is correct

Answer:

Step-by-step explanation:

1. Given that $53000 represents 100% of the original cost. You know that 6.9% as a percentage is equivalent to 0.069 as a decimal.

Increase in price:

           = 53000 * 0.069

           = $3657

2. The question states that the price of the car model is increasing, so you must add the original cost to the increase in price.

Price of next model:

           = 53000 + 3657

           = $56657

Answer:

63.62 inches squared

Step-by-step explanation:

The formula for the area of a circle is πr^2

r (Radius) is half of the diameter

r = 9/2

r = 4.5in

π x 4.5^2=

π x 20.25 = 63.6172512352

to 2 dp: 63.62 inches squared.

Answer:

The area of a plate with a diameter of 9 is 63.585

Step-by-step explanation:

A = πr²  use 3.14 as pi

r = [tex]\frac{1}{2}[/tex] d

[tex]\frac{1}{2}[/tex] × 9 = 4.5

r = 4.5

A = 3.14 × 4.5²

A = 3.14 × 20.25

A = 63.585

Answer: 4105.5

Step-by-step explanation:

The number of tickets sold in the previous year is 3723.

The percentage is a ratio that can be expressed as a fraction of 100.

Given that, the theater group sold 4380 tickets and which was 15% more than the tickets sold the previous year.

Therefore, the tickets sold in the previous year is:

4380 - 15% of 4380

= 4380 - 15×4380/100

= 4380 - 657

= 3723

Hence, the number of tickets sold in the previous year is 3723.

Hi Student!

In the question we are given two numbers and told to find the geometric mean of them.  A normal mean would be just taking the average by multiplying them against each other and dividing by two.  However, for geometric mean we multiply them against each other but put them inside of a square root.

[tex]mean = \sqrt{a*b}[/tex]

[tex]mean = \sqrt{40*30}[/tex]

[tex]mean = \sqrt{1200}[/tex]

[tex]mean = \sqrt{20^2*3}[/tex]

[tex]mean = 20\sqrt{3}[/tex]

Therefore, our geometric mean is [tex]34.64[/tex] or [tex]20\sqrt{3}[/tex].
