The values of Radius PQ if PQ = 24 and OR = 5. is 13 and The radius if PQ has length 24 and 9 units aways from center is 15 .

What is area of circle ?

Area of circle can be defined as  product of pi and square of radius.

Given,

In the chord PQ of O , point R is choosen so that OR is perpendicular to PQ.

The radius if PQ = 24 and OR = 5.

r = [tex]\sqrt{(24/2)^2 +5^2 }[/tex]

r = [tex]\sqrt{144+25}[/tex]

r = [tex]\sqrt{169}[/tex]

r = 13.

The radius if PQ has length 24 and 9 units aways from center.

radius  = [tex]\sqrt{(24/2)^2 + 9^2}[/tex]

= [tex]\sqrt{(12)^2 + 9^2}[/tex]

= [tex]\sqrt{144+81}[/tex]

= [tex]\sqrt{225}[/tex]

r = 15 .

The far from PQ from the center if it has length 16 and the circle has radius 10 is

PQ = [tex]\sqrt{10^2 - (16/2)^2}[/tex]

PQ = [tex]\sqrt{100-64}[/tex]

PQ = [tex]\sqrt{36}[/tex]

PQ = 6

The value of OR if PQ has length 6[tex]\sqrt{5}[/tex] and radius 9 .

OR = [tex]\sqrt{(9^2) - (3\sqrt{5})^2 }[/tex]

OR = [tex]\sqrt{81-45}[/tex]

OR = [tex]\sqrt{36}[/tex]

OR = 6 .

The value of OP .

OP = [tex]\sqrt{QR^2 + OR^2 }[/tex]

OP = [tex]\sqrt{(2\sqrt{3})^2 + (2\sqrt{2})^2 }[/tex]

OP = [tex]\sqrt{12+8}[/tex]

OP = 2[tex]\sqrt{5}[/tex]

Hence, the values of Radius PQ if PQ = 24 and OR = 5 is 13 and The radius if PQ has length 24 and 9 units aways from center is 15 .

What is Pythagoras theorem?

The hypotenuse's square is equal to the sum of the squares of the other two sides if a triangle has a straight angle (90 degrees), according to the Pythagoras theorem. Keep in mind that BC2 = AB2 + AC2 in the triangle ABC signifies this. Base AB, height AC, and hypotenuse BC are all used in this equation. The longest side of a right-angled triangle is its hypotenuse, it should be emphasized.

Here given in the question that one side of the wall 5 feet

So as it is a rectangular bedroom it can be split into 2 right-angled triangles.

So the hypotenuse of the triangle is 13 feet

Now using the Pythagoras theorem we can find out the length of the other wall

b²=h²-p²

(x-4)²+(x+6)² = (x+10)²

x²+16-8x+x²+36+12x = x²+100+20x

Answer: Let's call the present age of Emma x, the present age of Carson y, and the present age of their dad z.

From the information provided we know that:

x + y = (1/2)z + 4

We can find the value of z by isolating it:

x + y = (1/2)z + 4

x + y + 4 = (1/2)z + 4 + 4

x + y + 4 = (1/2)z + 8

2(x + y + 4) = z

We don't know the actual age of Emma, Carson and their dad, we only know the relationship between them.

The velocity of the ball when it returns to the ground is -8 m/s

An equation is an expression composed of variables and numbers linked together by mathematical operations.

The distance of a ball thrown upward is given by:

h(t) = -2t² + 12t - 10

The ball hits ground when h(t) = 0, hence:

-2t² + 12t - 10 = 0

t = 5 or 1

The velocity (V) of the ball is:

V = dh/dt

V = (d/dt)(-2t² + 12t - 10) = -4t + 12

V = -4t + 12

The ball hits ground when t = 5 or 1 s, hence:

The point corresponding to the transformed function y=f(x/x)+1 is approximately (-4, 4.25), (-2, 2.5), (0, 1), (1, -0.5), (3, 1). 

we need to substitute x/x = 1 for the argument of the function f(x) and add 1 to the result.

Transformed point on point y on f(x) = f(x/x) + 1

(x, f(x)) (x, f(x/x) + 1)

(-4, 5) (-4, f(-2) + 1) ≒ (-4, 4.25)

(-2, 3) (-2, f(-1) + 1) ≈ (-2, 2.5)

(0, 0) (0, f(0) + 1)

= (0, 1)

(1, -2) (1, f(1) + 1) ≈ (1, -0.5)

(3, -4) (3, f(3/3) + 1) ≈ (3, 1)

Note that for the point (-4,5) you have to substitute x/x = -1/2 instead of x/x = 2. This gives x = -8. So the corresponding transformed point is (-4, f(-8) + 1) ≈ (-4, 2.75).

f(x) and g(x) are inverses using composition

A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

To confirm the inverse relationship using composition.

For valid inverse f(g(x)) must be equal to g(f(x))

f(x) = ∛(x) + 13; g(x) = (x - 13)³:

f(g(x)) = f((x - 13)³)

f(g(x)) = ∛((x - 13)³) + 13

f(g(x)) = x - 13 + 13

f(g(x)) = x

g(f(x)) = g(∛(x) + 13)

g(f(x)) =  (∛(x) + 13 - 13)³

g(f(x)) =  (∛(x))³
g(f(x)) =  x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

f(x) = x³ + 1; g(x) = ∛(x - 1):

f(x) = x³ + 1; g(x) = ∛(x - 1)

f(g(x)) = f(∛(x - 1))

f(g(x)) =  (∛(x - 1))³ + 1

f(g(x)) =  x - 1 + 1

f(g(x)) =  x

g(f(x)) = g(x³ + 1)

g(f(x)) = ∛((x³ + 1) - 1)

g(f(x)) = ∛(x³)

g(f(x)) = x

Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

Answer:Slope=5

Step-by-step explanation

Answer:

Out of 50 students in a class, 40% are girls, meaning there are 50 x 40% = 20 girls in the class.

And the number of boys is 50 - 20 = 30 students.

If 30% of the girls wear spectacles, that means 30/100 x 20 = 6 girls wear spectacles.

And the number of girls not wearing spectacles is 20 - 6 = 14.

So the total number of girls wearing spectacles is 6, and the number of boys is 30, and the number of girls not wearing spectacles is 14.

This means that, in addition to what the employee contributes, the employer will match up to 6% of an employee's total compensation to his or her 401k account.

Employee compensation is the total remuneration that an organisation pays to an employee in exchange for the work that employee performed during the accounting period, whether that payment is made in cash or in kind. Taxes less subsidies on production include those due or owed on goods or services produced as outputs as well as other taxes or subsidies on production, such as those due on labour, equipment, buildings, or other assets used in production.

Employee compensation consists of two main parts:

(a) Salary and wages paid in cash or kind;

(b) Social insurance contributions that employers are required to pay, including contributions to social security programmes, actual social contributions to other employment-related social insurance programmes, and imputed social contributions to those same programmes.

0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)

Where:

If we know that P1(x, y) = (- 6, 4) and M(x, y) = (- 5, 6), then the coordinates of the other endpoint are:

0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)

r(p(x)) = r(p(38)) = r(38 * (1 - 0.25)) = r(28.5) = 28.5 - $5 = $23.50

p(r(x)) = p(r(38)) = p(38 - $5) = p(33) = 33 * (1 - 0.25) = $24.75

Answer:

CD = 15

Step-by-step explanation:

We are given two quadrilaterals: CDEF and GIJH.

We know that CD = 3x - 6, and GI = x + 8.

We want to find the length of CD.

Notice how CD and GI both have one tick mark on them.
This indicates that these two are congruent, meaning that they have the same length.

Because of that, CD = GI.

If we substitute 3x - 6 for CD and x + 8 for GI, we get:

3x - 6 = x + 8

Now, we can solve this like a regular equation.

Add 6 to both sides.

3x - 6 = x + 8

    +6       +6

_________________

3x = x + 14

Subtract x from both sides.

3x = x + 14

-x    -x

_____________-

2x = 14

Divide both sides by 2.

2x = 14

÷2    ÷2

x = 7

We found the value of x.

Now, substitute 7 as x in 3x-6 (the length of CD).

CD = 3x - 6 = 3(7) - 6 = 21 - 6 = 15

Therefore, CD = 15.
