Answer:

(x-3)²+(y-1)²=50

Step-by-step explanation:

we know,

general eqn of circle passing through a point is

r²=(x-h)²+(y-k)²------($)

then,at (-4,2) the eqn becomes

r²=(-4-h)²+(2-k)²----(1)

at (-2,6),

r²=(-2-h)²+(6-k)²-----(2)

at (4,8),

r²=(4-h)²+(8-k)²-------(3)

Now,

from (1) and(2),

(-4-h)²+(2-k)²=(-2-h)²+(6-k)²

or,16+8h+h²+4-4k+k²=4+4h+h²+36-12k+k²

or,h²-h²+8h-4h+k²-k²-4k+12k+16+4-4-36=0

or,4h+8k-20=0

or,4(h+2k)=20

or,h+2k=5------(4)

also,from (2) and (3),

(-2-h)²+(6-k)²=(4-h)²+(8-k)²

or,4+4h+h²+36-12k+k²=16-8h+h²+64-16k+k²

or,h²-h²+4h+8h+k²-k²-12k+16k+4+36-64-16=0

or,12h+4k-40=0

or,4(3h+k)=40

or,3h+k=10-------(5)

Now,multiplying eqn (5)by 2 then subtracting from (4),we get

h+2k=5

6h+2k=20

- - -

_________

-5h=-15

.:h=3

putting value of h in (4),we get

3+2k=5

or,2k=2

.:k=1

Now,putting value of k and h in eqn(1),

r²=(-7)²+(1)²

or,r²=49+1

.:r²=50

Now putting value of h,k and r² in eqn($),we get

(x-3)²+(y-1)²=50,which is required eqn of circle

Answer: No, 2/4 is not greater than 2/3

Step-by-step explanation: To find an easy way to calculate their values we have 2 options. So, the 1st option is to turn them into a decimal. I already calculated their values which are:

2/4 = 0.5

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.5 is not greater than 0.667.

The 2nd way is to find a common denominator, which would look like this:

2/4 =  6/12

2/3 =  8/12

8/12 is greater than 6/12, so that also proves that 2/4 is not greater than 2/3.

The change in the  angular velocity and number of revolutions  is given as,

when the angular velocity decreases the number of revolutions also decreases.

The rotation rate, which refers to how quickly an item rotates or circles in relation to another point, is measured vectorially by angular velocity.

Angular velocity can be defined as the speed at which an item rotates or revolves around an axis. The Greek letter omega stands for angular velocity. The SI unit of angular velocity is radians per second because it is measured in angle per unit time.

The only distinction between revolution and rotation is that the axis of rotation in a revolution is located outside the body. Both motions of an item or body in space are circular.

Answer:

perimeter of a triangle is the total

Step-by-step explanation:

p=48cm

Length=3x

width=x

Now P= 2(L+W)

48 =2(3x+x)

48=2(4x)

48=8x

dividing both sides by 8

we have x=6

and so length=18 and width =6

3) The rate of change on the interval [1, 7] is -1, so the correct option is A.

4) By using the rate of change formula, we will see that h(9) = 40

We know that for a function f(x), the average rate of change on the interval [a, b] is:

r = ( f(b) - f(a))/(b - a)

Here the interval is [1, 7]

Using the graph we can see that:

f(1)= 6

f(7) = 0

Then the average rate of change is:

r = ( f(7) - f(1))/(7 - 1)

r = (0 - 6)/6 = -1

The correct option is A.

4) Which will be value of h(9)?

We know that the average rate of change of h(x) is 7 on the interval [5, 9]

Then we can write:

7 = ( h(9) - h(5))/(9 - 5)

We know that h(15) = 12, then we have the equation:

7 = (h(9) - 12)/4

Now we can solve that for h(9), we will get:

7 = (h(9) - 12)/4

7*4 = h(9) - 12

28 = h(9) - 12

28 + 12 = h(9)

40 = h(9)

The solutions to the quadratic linear system equations are (11, 41) and (3, 9).

The given equations are y=x²-10x+30 and y=4x-3.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, y=x²-10x+30 -------(I) and y=4x-3 -------(II)

Substitute equation (II) in the equation (I), we get

4x-3=x²-10x+30

⇒ x²-10x+30-4x+3=0

⇒ x²-14x+33=0

⇒ x²-11x-3x+33=0

⇒ x(x-11)-3(x-11)=0

⇒ (x-11)(x-3)=0

⇒ x=11 and x=3

So, y=4(11)-3=41 and y=4(3)-3=9

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.

Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.

(a) Substituting 25 for t in the expression, we get:

[tex]A(25) = 200e^{0.0541 \times 25}[/tex]

         [tex]= 200e^{1.3525}[/tex]

Answer: 6.

Step-by-step explanation: We can solve this problem by using the combination formula:

C(n, r) = n! / (r! * (n - r)!)

In this case, n is the number of choices (the digits 2, 3, 4, 5, 6, and 9) and r is the number of items in each combination (4 digits).

Plugging in the values, we get:

C(6, 4) = 6! / (4! * 2!) = (6 * 5 * 4 * 3) / (4 * 3 * 2) = 30

Therefore, there are 30 four-digit odd numbers that can be formed using the digits 2, 3, 4, 5, 6, and 9. However, not all of these numbers will be less than 5000, so we need to further filter the list to only include those that meet this requirement.

The four-digit odd numbers that can be formed using these digits are:

2359, 2395, 2539, 2593, 2935, 2953, 3259, 3295, 3529, 3592,

Out of these numbers, only 2359, 2539, 2935, 3925, 5239, and 9523 are less than 5000. Therefore, there are 6 four-digit odd numbers less than 5000 that can be formed using the digits 2, 3, 4, 5, 6, and 9.

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.

An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.

It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as

f(x) = 0.48 ln(x+2) + 27

Here x is the distance in miles from the eye of the hurricane.

f(x) is the pressure of the mercury in a barometer in inches

So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is

(Here f(x) = 28)

f(x) = 0.48 ln(x+2) + 27

⇒ 28 = 0.48 ln(x+2) + 27

⇒ 0.48 ln(x+2) = 28 - 27

⇒ ln (x+2) = 1/0.48

⇒ ln(x+2) = 2.0833

Applying exponential base "e" on both sides, we get

(x+2) = [tex]e^{2.0833}[/tex]

⇒ x + 2 = 8.0309

⇒ x = 8.0309 - 2 = 6.0309

When the result is rounded to the nearest whole number, we get x = 6 miles.

Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

Answer: To find out how many seconds it will take for the egg to hit the ground, we need to find the value of x when the height of the egg is 0 feet. We can do this by setting the height of the egg equal to 0 in the equation 27 - 16x^2 and solving for x.

The equation for the height of the egg in feet x seconds after being dropped is given as:

27 - 16x^2 = 0

Subtracting 27 from both sides of the equation gives us:

-16x^2 = -27

Dividing both sides of the equation by -16 gives us:

x^2 = 27/16

Taking the square root of both sides of the equation gives us:

x = sqrt(27/16)

Plugging this value into the equation for the height of the egg gives us:

27 - 16(sqrt(27/16))^2 = 0

Simplifying this equation gives us:

27 - 16(27/16) = 0

Which simplifies to:

27 - 27 = 0

This equation is true, so the value of x that we found is a solution to the equation. This means that the egg will hit the ground after sqrt(27/16) seconds.

⇒ Hypotenuse = 132.35

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The values are,

⇒ θ = 20° opposite = 45

Now,

Since, The values are,

⇒ θ = 20° opposite = 45

We know that;

⇒ sin θ = Opposite / Hypotenuse

⇒ sin 20° = 45 / Hypotenuse

⇒ Hypotenuse = 45 / sin 20°

⇒ Hypotenuse = 45 / 0.34

⇒ Hypotenuse = 132.35

Thus, The value of hypotenuse will be;

⇒ Hypotenuse = 132.35
