Graph 3x2 + 3y2 = 75

Answer:

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

Step-by-step explanation:

First we will define the perimeter.

The continuous line which forms the boundary of a closed geometric figure.

To find the perimeter of any geometrical shape the lengths of its outer boundary lines are added.

So for the first shape with sides 10ft, 4ft, 3ft and 9ft, we don't know the lengths of two sides

1. The side parallel to the 10ft side

and

2. The side parallel to 9ft side.

So the lengths of side will be:

For 1,

10-3 = 7ft

For 2,

9-4= 5ft

the perimeter will be:

=> 10+4+3+9+5+7

=> 38 ft

And for the second shape with sides 6 in ,5 in, 4 in, 3 in, 2 in and 10 in,

the length of one unknown side will be 6 inches as it is parallel and equal in length to the side with 6 in length,

And the length of side that is parallel to the side with length 4 inches will be same.

The perimeter will be:

=>6+5+4+3+2+10+6+4

=> 40 inches

So,

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

1. The perimeter of shape is 33 ft.

2. The perimeter of the shape is 40 in ( option B)

The perimeter of a shape is the total length of its boundary or the sum of all its sides. It measures the distance around the shape and is calculated by adding the lengths of its individual sides.

1. The unknown side of the figure is calculated as;

10-3 = 7ft.

The perimeter of the figure is obtained by adding all the sides;

Perimeter = 10+7 + 4 + 3 + 9

= 33 ft.

Therefore the perimeter of the figure is 33ft.

2. The perimeter of the shape = 6 + 6+ 10+5+4+3+2+4 = 40 in

Answer:

x = 5.5

Step-by-step explanation:

Given 2 secants intersecting the circle from a point outside the circle then

The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

x(x + 14) = 6(6 + 12)

x² + 14x = 6 × 18 = 108 ( subtract 108 from both sides )

x² + 14x - 108 = 0 ← in standard form

with a = 1, b = 14 and c = - 108

Using the quadratic formula to solve for x

x = ( - b ± [tex]\sqrt{b^2-4ac}[/tex] ) / 2a

  = ( - 14 ± [tex]\sqrt{14^2-(4(1)(-108)}[/tex] ) / 2

  = ( - 14 ± [tex]\sqrt{196+432}[/tex] ) / 2

  = ( - 14 ± [tex]\sqrt{628}[/tex] ) / 2

  x = [tex]\frac{-14-\sqrt{628} }{2}[/tex] or x = [tex]\frac{-14+\sqrt{628} }{2}[/tex]

  x = - 19.5 or x = 5.5 ( to 1 dec. place )

However x > 0 ⇒ x = 5.5

Angie’s current equity on her car is 2,000

Answer:

[tex]\$2,000[/tex]

Step-by-step explanation:

Equity is defined by difference between total value of the asset and total liabilities.

Value of Angie's car is [tex]\$22,000[/tex] and she owes [tex]\$20,000[/tex] which means:

Total value of asset (car) = [tex]\$22,000[/tex]

Total liability = [tex]\$22,000[/tex]

∴ Equity = [tex]22000 - 20000 = 2000[/tex]

Hence Angie's current equity is [tex]\$2,000[/tex]

Answer:

10

Step-by-step explanation:

you can add the short section (AB) and the longer section (BC) to get AC which is 3+7=10

According to basic geometric principles, the length of a continuous straight line is the sum of the lengths of its segments. Therefore, if AB = 3 and BC = 7, then AC = AB + BC, which equals 10.

In Mathematics, specifically in geometry, when we talk about points and lines, if AB = 3 and BC = 7, then the whole length of the line AC, which includes AB and BC, is simply the sum of AB and BC. Therefore, AC = AB + BC.

To calculate it, just add these two lengths together, 3 + 7, which equals 10. So, AC = 10.

This is a fundamental principle in math that when you have a continuous straight line divided into segments, the total length of the line is equal to the sum of the lengths of its segments. This can be easily visualized if you imagine a ruler, with AB being the first 3 units, and BC being the next 7 units. The total length AC represents all 10 units.

To find the vertex of a parabola given an equation, you can use the formula x = -b/2a to find the x-coordinate and then substitute it back to find the y-coordinate.

The equation of the parabola is given as y = -1/4x² + 4x - 19. To find the coordinates of the vertex, we use the formula x = -b/2a to find the x-coordinate, and then substitute it back into the equation to find the y-coordinate.

Here, a = -1/4 and b = 4. Plugging these values into x = -b/2a, we get x = -4/(2×(-1/4)) = 4. Substituting x = 4 back into the equation gives us y = -1/4(4)² + 4(4) - 19 = -1.

Therefore, the coordinates of the vertex of the parabola are (4, -1).

Step-by-step explanation:

Answer:

Step-by-step explanation:

(Tangent Length)^2 = y*(y + 11)   You are going to have to use the quadratic formula on this.

Tangent Length = 7

7^2 = y * (y + 11)

49 = y^2 + 11y  

0 = y^2 + 11y - 49

a = 1

b = 11

Step-by-step explanation:

The two benches divide the length of the path into thirds.  The length of each third is 2.4 miles / 3, or 0.8 mile.

The first bench is at 0.8 mile from the beginning, and the second is at 2(0.8 mile), or 1.6 mile from the beginning.

Answer:

D, B

Step-by-step explanation:

Remember SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

In the first triangle, for angle A, 11 is the adjacent leg, 60 is the opposite leg, and 61 is the hypotenuse.  Therefore:

sin A = 60/61 = 0.98

cos A = 11/61 = 0.18

tan A = 60/11 = 5.45

So the correct answer is D.

In the second triangle, for angle Y, 16 is the adjacent leg and 65 is the hypotenuse.  To find the sine, we need to know the opposite leg.  So first, use Pythagorean theorem to find the opposite leg.

c² = a² + b²

65² = 16² + b²

4225 = 256 + b²

b² = 3969

b = 63

So the sine of Y is:

sin Y = 63 / 65

Answer B.

1. From the given right angle triangle, the adjacent side of angle A is 11 units.

The hypotenuse is 61 units.

We use the cosine ratio to get:

[tex] \cos(A) = \frac{adjacent}{hypotenuse} [/tex]

We substitute to obtain;

[tex]\cos(A) = \frac{11}{61} [/tex]

[tex]\cos(A) = 0.18[/tex]

[tex]A=\cos^{ - 1} (0.18)[/tex]

The correct choice is D.

2. From the given right triangle,

[tex]XZ^2 + {16}^{2} = {65}^{2} [/tex]

[tex]XZ^2 + 256 =4225[/tex]

[tex]XZ^2 =4225 - 256[/tex]

[tex]XZ^2 =3969[/tex]

Take positive square root

[tex]XZ=\sqrt{3969}[/tex]

[tex]XZ=63[/tex]

[tex] \sin(Y) = \frac{opposite}{hypotenuse} [/tex]

[tex]\sin(Y) = \frac{63}{65} [/tex]

The correct answer is B

Answer:

31.9 degrees

Step-by-step explanation:

tan(A) = 5.1/8.2

A = tan^-1 (5.1/8.2) = 31.9 degrees

The measure of angle A is 31.1 degrees.

To find the measure of angle A, we can use the following trigonometric function:

tan(A) = opposite over adjacent

In this case, the opposite side is 5.1 and the adjacent side is 8.2. Plugging these values into the formula, we get:

tan(A) = 5.1 / 8.2

A = tan⁻¹(5.1 / 8.2)

A ≈ 31.1 degrees

Therefore, the measure of angle A is 31.1 degrees (rounded to one decimal place).

Answer:

302 m³

Step-by-step explanation:

The volume (V) of a cone is calculated using the formula

V = [tex]\frac{1}{3}[/tex] πr²h

where r is the radius and h the height

Consider the right triangle from the vertex of the cone to the midpoint of the base and the radius

with hypotenuse = 10 cm

h² + 6² = 10²

h² + 36 = 100 ( subtract 36 from both sides )

h² = 64 ( take the square root of both sides )

h = [tex]\sqrt{64}[/tex] = 8

Hence

V = [tex]\frac{1}{3}[/tex] π × 6² × 8

  = [tex]\frac{1}{3}[/tex] π × 36 × 8

   = [tex]\frac{36(8)\pi }{3}[/tex] ≈ 302 m³

This is a secant-tangent problem.

(Whole)(outside) = (tangent)^2

(x + 12)(x) = 8^2

x^2 + 12x = 64

x^2 + 12x - 64 = 0

In this quadratic equation, we see that a = 1, b = 12 and c = -64.

Plug those values into the quadratic formula and solve for x.

Answer:

x = 4

Step-by-step explanation:

Given a secant and a tangent drawn from an external point to the circle, then

The square of the measure of the tangent is equal to the product of the external part and the entire secant, that is

x(x + 12) = 8²

x² + 12x = 64 ( subtract 64 from both sides )

x² + 12x - 64 = 0 ← in standard form

with a = 1, b = 12 and c = - 64

Using the quadratic formula to solve for x

x = ( - 12 ± [tex]\sqrt{12^2-(4(1)(-64)}[/tex] ) / 2

  = ( - 12 ± [tex]\sqrt{144+256}[/tex] ) / 2

  = ( - 12 ± [tex]\sqrt{400}[/tex] ) / 2

Answer:

The correct answer option is C. . \

Answer:

Choice c.

Step-by-step explanation:

The domain of a rational function is found where the denominator of the fraction is equal to 0.  These are the values that are NOT allowed.  We have to factor the denominator completely to find these values that make the denominator equal 0.  In other words, our denominator right now is:

[tex]x(x^2-16)[/tex]

we set each factor equal to 0:

x = 0 or

[tex]x^2-16=0[/tex]

The left side of that quadratic is the difference of perfect squares, so it factors into the 2 binomials:

(x + 4)(x - 4)

Setting each of those equal to 0 we can solve for the values of x that are not allowed:

If x + 4 = 0, then

x ≠ 4.

If x - 4 = 0, then

x ≠ -4

So the domain for this rational function is:

{x I x ≠ ±4, x ≠ 0},

which is c.
