Answer: (6,11π/6).

Step-by-step explanation:We need to find the radius r and the angle θ. Remember that r2=x2+y2, so

because of the signs of x and y, our angle is in quadrant IV. Therefore, we find that θ=11π/6.

So the final answer is (6,11π6).

The perimeter of Stephanie's triangle is 12.5 ft.

According to the statement

we have to find the perimeter of Stephanie's triangle.

So, For this purpose,we know that the

The perimeter of a triangle is the sum of all side lengths of the triangle.

From the given information:

Let the sides of Juan's triangle be x, y and z. So:

x =5, y =8,z =12.

Then

The perimeter (J) of Juan's triangle is calculated by adding all sides.

Perimeter = x+y+z

So:

perimeter = 5+8+12

Perimeter = 25

From the question, we understand that:

The perimeter (S) of Stephanie's triangle is half that of Juan.

Answer:

$10,579, assuming that 22% is the rate per month

Step-by-step explanation:

Here, I'll assume that the interest rate is per month.

The simple interest formula is \(I=Prt\) (Interest = principal * rate * time). The rate and time need to use the same units.

The principal is $3550, the rate is 0.22, and the time is 9, so \(I=(3550)(0.22)(9)\). The product is 7029.

This is added to how much money he already has: 7029+3550=10579

Step-by-step explanation:

Answer:

His son present age is 20 years

His present age is 40 years

Step-by-step explanation:

Assume that this son's age now is x years

∵ His son's age now = x years

∵ Ankit age is twice as old as his son

→ Twice means × 2

∴ Ankit age = 2 × x = 2x years

→ In for years means after 4 years (add)

∵ His age in four years = 2x + 4

→ 9 years ago means before 9 years (subtract)

∵ His son 9 years ago = x - 9

∵ In 4 years he will be four times as old as what his son was 9 years ago

→ That means 2x + 4 = 4 × (x - 9)

∴ 2x + 4 = 4(x - 9)

→ Let us solve the equation to find x

∴ 2x + 4 = 4(x) - 4(9)

∴ 2x + 4 = 4x - 36

→ Subtract 4 from both sides

∵ 2x + 4 - 4 = 4x - 36 - 4

∴ 2x = 4x - 40

→ Subtract 4x from both sides

∵ 2x - 4x = 4x - 4x - 40

∴ -2x = -40

→ Divide both sides by -2

∵ \(\frac{-2x}{-2}\) = \(\frac{-40}{-2}\)

∴ x = 20

∵ x represents the present age of his son

∴ His son present age is 20 years

∵ 2x represents his present age

∵ 2(20) = 40

∴ His present age is 40 years

The length of the two segments, written as radicals, are:

AB = √117

PQ = √244

Remember that for a segment whose endpoints are (x₁, y₁) and (x₂, y₂), the length of the segment is:

L = √( (x₂ - x₁)² + (y₂ - y₁)²)

First, for the segment AB the endpoints are:

A = (-4,  -4)

B = (2, 5)

Then the length is:

L =  √( (-4 - 2)² + (-4 - 5)²)

L = √117

For the segment PQ the endpoints are:

Q = (6, -2)

The length is:

Step-by-step explanation:

The radius of the cone is 3ft

The base area of the cone is 28.26ft²

The volume of the given cone is 75.36ft³

The formula for calculating the volume of a cone is expressed as:

\(V = \frac{1}{3} \pi r^2 h\)

r is the base radius

h is the height of the cone

V is the volume of the cone

From the diagram, the base diameter is 6 ft

Base radius = 6/2 = 3ft

The area of the base of the cone is \(\pi r^2 h\)

Base area = \(3.14 \times 3^2\ = 28.26ft^2\)

Get the required volume of the cone

Volume = Base area/3

Volume = \(\frac{1}{3} \times 28.26 \times 8 = 75.36ft^3\)

Hence the volume of the given cone is 75.36ft³

44.125 inches

Step-by-step explanation:

Given that:

Length of picture = 32 1/2 inches

Length of wall = 120 3/4 inches

Hence, to center picture horizontally ;

Distance from the edge of the wall in which the picture should be placed :

(Length of wall - length of picture) / 2

(120 3/4 - 32 1/2) / 2

(483/4 - 65/2) / 2

Take the L. C. M of 4 and 2 = 4

((483 - 130) / 4) ÷ 2

(353 / 4) ÷ 2

(353 / 4) * (1 / 2)

= 353 / 8

= 44 1/8

= 44 1/8

= 44.125 inches

The space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.

Answer:

The possible values are a = -2.5 or a = 4.5.

Step-by-step explanation:

Composite function:

The composite function of f(x) and g(x) is given by:

\((f \circ g)(x) = f(g(x))\)

In this case:

\(f(x) = 4x^2 - 8x - 20\)

\(g(x) = 2x + a\)

So

\((f \circ g)(x) = f(g(x)) = f(2x + a) = 4(2x + a)^2 - 8(2x + a) - 20 = 4(4x^2 + 4ax + a^2) - 16x - 8a - 20 = 16x^2 + 16ax + 4a^2 - 16x - 8a - 20 = 16x^2 +(16a-16)x + 4a^2 - 8a - 20\)

Value of a so that the y-intercept of the graph of the composite function (fog)(x) is (0, 25).

This means that when \(x = 0, f(g(x)) = 25\). So

\(4a^2 - 8a - 20 = 25\)

\(4a^2 - 8a - 45 = 0\)

Solving a quadratic equation, by Bhaskara:

\(\Delta = (-8)^2 - 4(4)(-45) = 784\)

\(x_{1} = \frac{-(-8) + \sqrt{784}}{2*(4)} = \frac{36}{8} = 4.5\)

\(x_{2} = \frac{-(-8) - \sqrt{784}}{2*(4)} = -\frac{20}{8} = -2.5\)

The possible values are a = -2.5 or a = 4.5.
