Answer:

Get the equation in the form y = ax2 + bx + c.

Calculate -b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

Step-by-step explanation:

∠ PAR is an angle at the centre of the circle subtended by the arc PR

The central angle is equal to the arc that subtends it, thus

∠ PAR = arc PH + arc HR = 80° + 45° = 125° → D

In isosceles triangle ABC with AB=AC=4, and AH=3HC, the length of BC is [tex]\( \frac{4\sqrt{5}}{5} \)[/tex] units, determined using the Pythagorean Theorem and the given relationship between AH and HC.

In isosceles triangle ABC, let BH be the altitude from B to side AC. Given AB = AC = 4 and AH = [tex]3 \cdot[/tex] HC, we can use the Pythagorean Theorem in right triangle ABH:

[tex]\[ BH^2 + AH^2 = AB^2 \][/tex]

Substitute the given values:

[tex]\[ BH^2 + (3HC)^2 = 4^2 \][/tex]

Simplify:

[tex]\[ BH^2 + 9HC^2 = 16 \][/tex]

Since BH = HC in an isosceles triangle, substitute BH with HC:

[tex]\[ HC^2 + 9HC^2 = 16 \][/tex]

Combine like terms:

[tex]\[ 10HC^2 = 16 \][/tex]

Solve for HC :

[tex]\[ HC^2 = \frac{8}{5} \][/tex]

Now, use the Pythagorean Theorem in right triangle BHC:

[tex]\[ BC^2 = BH^2 + HC^2 \][/tex]

Substitute the known values:

[tex]\[ BC^2 = HC^2 + HC^2 \]\[ BC^2 = 2HC^2 \]\[ BC^2 = 2 \cdot \frac{8}{5} \]\[ BC^2 = \frac{16}{5} \][/tex]

Therefore, BC is the square root of [tex]\( \frac{16}{5} \)[/tex], which simplifies to [tex]\( \frac{4}{\sqrt{5}} \)[/tex] or [tex]\( \frac{4\sqrt{5}}{5} \)[/tex].

The length of BC in an isosceles triangle with sides AB=AC=4 and altitude BH, where AH=3(HC), is 2√2 units.

To determine the length of BC in an isosceles triangle ABC with sides AB=AC=4 and altitude BH, where AH=3(HC), we can use the properties of similar triangles and the Pythagorean theorem.

Since the triangle is isosceles, the altitude BH will bisect the base AC at H, creating two right triangles ABH and CBH. We know that AH=3(HC), which can be expressed as AH=3x and HC=x for some value x. Therefore, AC = AH + HC = 3x + x = 4x.

Using the Pythagorean theorem (a² + b² = c²), in triangle ABH, we get:

And in triangle HBC, we have:

Since we want to find BC, we first solve for BH from the first right triangle:

Substitute BH² into the second equation:

To find x, we use AC = 4x = 4, thus x = 1. Substituting x into the equation for BC, we get:

Answer:

-14>-1 2/3

Step-by-step explanation:

Step-by-step explanation:

After the translation, rotation and reflection position of the image may differ but the side lengths, angle, orientation remains the same, so that the congruence is maintained, but in dilation the size of the image may get enlarged or reduced, so that congruence is not there.

Parallelograms are congruent when

Reflect across the y- axis and then translate 1 unit left.

Reflect across the y- axis then rotate 45° counterclockwise.

Translate 4 units up then rotate 180° counterclockwise

Parallelograms are non-congruent when

Translate 5 units right then dilate by a factor of 2

Rotate 90° clockwise then dilate by a factor of 6

Dilate by a factor of 3 then reflect across the x- axis

Answer:

[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] - 7

Step-by-step explanation:

Note the common difference d between consecutive terms in the sequence, that is

d = - 35 - (- 28) = - 42 - (- 35) = - 49 - (- 42) = - 7

Thus to obtain a term in the sequence subtract 7 from the previous term

[tex]a_{n+1[/tex] = [tex]a_{n}[/tex] - 7 with a₁ = - 28

Elle experienced a 22.22% decrease in earnings from babysitting, from $45 to $35. This is calculated by finding the difference between the two amounts, dividing by the original amount, and then multiplying by 100 to convert to a percentage.

Elle's decrease in earnings can be calculated using the formula for calculating the percentage decrease, which is [(Original value - New value)/(Original value)] * 100.

In Elle's case, the original value is $45 (the amount she earned last month), and the new value is $35 (the amount she earned this month). So, follow the formula:

So, Elle experienced a 22.22% decrease in her earnings from babysitting.

Length of the rectangle is 8m and width is 6m

Step-by-step explanation:

48 = x (x - 2)

48 = x² - 2x

x² - 2x - 48 = 0

x² - 8x + 6x - 48 = 0

x(x - 8) + 6(x - 8) = 0

(x + 6)(x - 8) = 0

x = -6, 8 (neglecting the negative value)

∴ Length of the rectangle = 8m

∴ Width of the rectangle = 8 - 2 = 6m

The solution to the system of equations is (7, 13/3).

We have Equations,

y= 1/3x + 2,

y= 4/3 x - 5

Solving above two equations we get

1/3 x + 2 = 4/ 3 x - 5

1/3 x - 4/3 x = -5 - 2

-3/3 x = -7

-x = -7

x = 7

and, y = 4/3(7) - 5 = 28/3-5 = 13/3

Thus, the solution of equation is (7, 13/3).

Option D:

x = 8

Solution:

Given data:

m∠FGH = 148° , m∠FGL = (x + 12)°  and m∠LGH = (16x)°

To find the value of x:

m∠FGL + m∠LGH = m∠FGH

⇒ (x + 12)°  + (16x)° = 148°

⇒ x° + 12°  + 16x° = 148°

⇒ 17x° + 12° = 148°

Subtract 12° from both sides of the equation.

⇒ 17x° = 136°

Divide by 17 on both sides, we get

⇒ x° = 8°

⇒ x = 8

The balance after four years is $1129.27

Step-by-step explanation:

The formula for compound interest, including principal sum, is [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

∵ $800 is deposited in an account

∴ P = 800

∵ The account pays 9% annual interest

∴ r = 9% = 9 ÷ 100 = 0.09

∵ The interest is compounded annually

∴ n = 1

∵ The time is 4 years

∴ t = 4

- Substitute the values of P, r, n, and t in the formula above

∵ [tex]A=800(1+\frac{0.09}{1})^{(1)(4)}[/tex]

∴ [tex]A=800(1.09)^{4}[/tex]

∴ A = 1129.265

∴ The balance after four years is $1129.27
