THIRD TIME ASKING FOR HELP PLEASE HELP ME!!!!!!!!!!!!!!!!!!!Given Right Triangle ABC With Altitude BD

Answers

Answer 1
Answer:  9 units

========================================================

Explanation:

For now, focus on triangle ABD. This is a right triangle due to BD being an altitude.

Use the pythagorean theorem to find that...

(AD)^2 + (BD)^2 = (AB)^2

(1)^2 + (BD)^2 = (3)^2

1 + (BD)^2 = 9

(BD)^2 = 9-1

(BD)^2 = 8

Normally we would isolate BD itself, but I'll stop short and use that last line instead.

------------------

The triangles ABD and BCD are similar triangles (we can prove this using the AA similarity theorem).

Since we have similar triangles, we can form the proportion shown below

AD/BD = BD/CD

This cross multiplies to

AD*CD = (BD)^2

We know that AD = 1 and (BD)^2 = 8, so,

AD*CD = (BD)^2

1*CD = 8

CD = 8

This then means,

x = CD+DA

x = 8+1

x = 9

AC is 9 units long.

determine the equation of the circle graphed below.

( please help me )

Answers

Answer:

(x - 3)² + (y + 5)² = 10

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (3, - 5 ) , then

(x - 3)² + (y - (- 5) )² = r² , that is

(x - 3)² + (y + 5)² = r²

r is the distance from the centre to a point on the line

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (6, - 4)

r = [tex]\sqrt{(6-3)^2+(-4+5)^2}[/tex]

  = [tex]\sqrt{3^2+1^2}[/tex]

  = [tex]\sqrt{9+1}[/tex]

   = [tex]\sqrt{10}[/tex] ⇒ r² = ([tex]\sqrt{10}[/tex] )² = 10

(x - 3)² + (y + 5)² = 10 ← equation of circle

isosceles right

Step-by-step explanation:

It is an isosceles right angled triangle because according to the figure it's two sides are equal which means it is isosceles triangle and there is 90 degree symbol which denotes right angle.

An Isosceles Right Triangle is a right triangle that consists of two equal length legs. Since the two legs of the right triangle are equal in length, the corresponding angles would also be congruent. Thus, in an isosceles right triangle, two legs and the two acute angles are congruent.

64, 16, 4, 1 converging or diverging

Answers

Answer:

The series 64, 16, 4, 1 is convergent.

Step-by-step explanation:

Let be [tex]\{x_{1}, x_{2},...,x_{n}\}[/tex] the set of values of the series. A series is convergent if and only if:

[tex]\frac{x_{i + 1}}{x_{i}} < 1, \, \forall\,i\in \mathbb{N}[/tex] (1)

If we know that [tex]x_{1} = 64[/tex], [tex]x_{2} = 16[/tex], [tex]x_{3} = 4[/tex] and [tex]x_{4} = 1[/tex], then the convergence ratio of each pair of consecutive values are, respectively:

[tex]\frac{x_{2}}{x_{1}} = \frac{1}{4}[/tex], [tex]\frac{x_{3}}{x_{2}} = \frac{1}{4}[/tex], [tex]\frac{x_{4}}{x_{3}} = \frac{1}{4}[/tex]

Hence, the series 64, 16, 4, 1 is convergent.

∠aangle, a and \angle b∠bangle, b are complementary angles. \angle a∠aangle, a measures 55^\circ55 ∘ 55, degrees. What is the measure of \angle b∠bangle, b? \Large{^\circ} ∘

Answers

Answer:

35

Step-by-step explanation:

Cause they both add up to a right angle which is 90 degrees. so 90-55=35

angle, a and ∠angle, b are complementary angles. ∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees. so we can conclude that ∠b = 35.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

angle, a and ∠angle, b are complementary angles.

∠ an ∠angle, a measures 5 5 ∘ 55 ∘ 55, degrees.

we want to measure ∠ b

We know that the sum of Complementary angles is equal to 90 degrees.

so to find the measure of angle B we subtract the given angle from 90

∠ b + ∠ a = 90

∠ b + 55 = 90

∠ b = 90-55

∠ b =35

so we can conclude that ∠b = 35.

Daniel is creating a rectangular garden in his back yard. The length of the garden is 14 feet. The perimeter of the garden must be at least 58 feet and no more than 66 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.

Answers

Answer:

15 ≤ w ≤ 19

Step-by-step explanation:

Given that :

Length of garden = 14 feets

Perimeter must be atleast 58 but no more than 66

The range of value for the width ;

Perimeter = 2 length + 2 width

Perimeter = 2(14) + 2w

If perimeter = 58

58 = 28 + 2w

58 - 28 = 2w

30 /2 = w

w = 15

If perimeter = 66

66 = 28 + 2w

66 - 28 = 2w

38 = 2w

w = 38 / 2

w = 19

Range of the width should be atleast 15 and not more Than 19

Hence,

15 ≤ w ≤ 19

5x² = 180

x² = 36

Answer:

x = - 6, x = 6

Step-by-step explanation:

Given

h(x) = - 5x² + 180

To find the zeros let h(x) = 0 , that is

- 5x² + 180 = 0 ( subtract 180 from both sides )

- 5x² = - 180 ( divide both sides by - 5 )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] = ± 6 , then

lesser x = - 6

Which equations can pair with y = 3x – 2 to create a consistent and independent system? x = 3y – 2 y = –3x – 2 y = 3x + 2 6x – 2y = 4 3y – x = –2

Answers

Answer:

[tex](a)\ x = 3y - 2[/tex]

[tex](b)\ y = -3x - 2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Step-by-step explanation:

Given

[tex]y =3x -2[/tex]

Required

Equations that can create consistent and independent systems

For a pair of equation to have consistent and independent systems, the equations must have different slopes.

An equation of the form [tex]y = mx + c[/tex] has m has its slope.

In [tex]y =3x -2[/tex]

[tex]m = 3[/tex] --- slope

Considering the options

[tex](a)\ x = 3y - 2[/tex]

Make y the subject

[tex]x = 3y - 2[/tex]

[tex]3y = x+2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x+\frac{2}{3}[/tex]

The slope is:

[tex]m_1 = \frac{1}{3}[/tex]

Hence, (a) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](b)\ y = -3x - 2[/tex]

The slope is:

[tex]m= -3[/tex]

Hence, (b) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](c)\ y = 3x + 2[/tex]

The slope is:

[tex]m=3[/tex]

Hence, (c) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](d)\ 6x - 2y = 4[/tex]

Make y the subject

[tex]2y = 6x -4[/tex]

Divide by 2

[tex]y = 3x -2[/tex]

The slope is

[tex]m =3[/tex]

Hence, (d) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Make y the subject

[tex]3y = x -2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x -\frac{2}{3}[/tex]

The slope is:

[tex]m = \frac{1}{3}[/tex]

Hence, (e) can make a consistent and independent system with [tex]y =3x -2[/tex]

A grocery store has a sale on apples. Shoppers can buy 3 bags of apples for $5. Each bag contains 6 apples. Which of the following statements is true?

Answers

Answer:

i dont know

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

3b = 5$

3b = 6a

3b = 3 bags

6a = 6 apples

A. It costs 3.60 for 1 bag of apples

3.60 + 3.60 = 60 + 60 = 120 + 3 = 123 + 3 = 126

Meaning it would cost 126 for 3 bags of apples making this a incorrect option

B. It costs 3.60 for 1 apple

B is wrong because its one apple and if we were to subtract the apple would probably only cost a few change not 3$ and 60 cents.

C. The cost of 9 bags of apples is 30$

9b = 21a, its either c or d but I'm pretty sure its D!

D. The cost of 108 apples is 30$

D is correct

The sum of a number and two times a smaller number is 62. Three times the bigger number exceeds the smaller number by 116. What are the numbers?

Answers

Answer:

SMALLER NUMBER = 14

BIGGER NUMNER = 34

Step-by-step explanation:

Two equations can be derived from the question

a + 2b = 62 equation 1

3a - b = 116  equation 2

a = bigger number

b = smaller number

multiply equation 1 by 3

3a + 6b = 186 equation 3

subtract equation 2 from 3

5b = 70

b = 14

substitute for b in equation 1

a + 28 = 62

a = 34
