Step-by-step explanation:

The half diagonals of a rhombus are the legs of a right triangle with the hypotenuse being the side of the rhombus.

EG and FH are the diagonals of the rhombus. The half-diagonals measure 8 and 6.

We can use the Pythagorean theorem to find the hypotenuse length with is the length of the side of the rhombus.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = c^2

100 = c^2

c^2 = 100

c = 10

Answer: 10 units

The length of one side of the rhombus is 10 units.

A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.

Given that,

EFGH is a rhombus.

Length of the two diagonals are also given.

EG = 16 and FH = 12

In a rhombus, the diagonals bisect each other at right angles.

Let the intersection point of the diagonals be O.

Consider ΔOFG.

Using Pythagoras Theorem,

(FG)² = (OG)² + (OF)²

OG = EG / 2 = 16 / 2 = 8

OF = FH / 2 = 12 / 2 = 6

(FG)² = 8² + 6²

        = 100

FG = √100 = 10

Hence the length of one side of the rhombus is 10 units.

3 waters  

2.75s + 2(3) ≤ 15  

2.75 + 6 ≤ 15  

Subtract 6 from both sides

Hope this helps?

Inequality which represents the number of sodas is 0 ≤ s ≤ 3.

Given:

Alexandra has $15.

Cost of soda = $2.75

Cost of bottled water = $2.00

2.75s + 2w ≤ 15

Let, number of sodas be s.

number of bottled water be w.

Three Alexandra's friends asked for water.

∴ w = 3

⇒ 2.75s + 2(3) ≤ 15

⇒ 2.75s + 6 ≤ 15

Subtracting 6 from the both sides, we get:

⇒ 2.75s ≤ 15 - 6

⇒ 2.75s ≤ 9

Divide both sides by 2.75, we get:

⇒ s ≤ 9/2.75

⇒ s ≤ 3.27

But the number of sodas (s) should be a whole number and not an integer.

⇒ s ≤ 3

⇒ 0 ≤ s ≤ 3

Therefore, the inequality which represents the number of sodas she can

The probability of drawing three queens in a row from a standard deck of cards, starting with the first card drawn as a queen and with no replacement, is approximately 0.0181% or 0.000181.

The probability of drawing a queen from a deck of 52 cards, given that the first card drawn was a queen and that cards are not replaced, involves a combination of multiplying probabilities for independent events:

To find the total probability of drawing three queens in a row, we multiply these independent probabilities together: (1/13) * (3/51) * (2/50). This totals to approximately 0.000181, or 0.0181%, which is the probability of drawing three queens in a row from a standard deck of cards without replacement after drawing the first queen.

Answer: X=16

Step-by-step explanation: Add 90 and 22 and you will get 112. Since the beginning of the equation is "7x" which is multiplication you use Inverse Operations. So, you divide the sum, 112, by 7. Your answer will be 16.

Step-by-step explanation:

If (p, 0) and (q, 0) are x-intercepts, then p and q are zeros.

The intercept form of an equation of a quadratic function:

y = a(x - p)(x - q)

p, q - x-intercepts (zeros).

We have the equation: y = 2(x + 4)(x - 6) = 2(x - (-4))(x - 6)

Therefore the x-intercepts are -4 and 6.

The zeros are -4 and 6 too.

Answer:

Around $93.65

Step-by-step explanation:

(1 - 37%)(x) = 59

(0.63)(x) = 59

x = 93.65

Final answer:

To find the original price of the printer before a 37% discount, we set up an equation and solve for the original price. After solving, the original price is found to be approximately $93.65.

Explanation:

To calculate the original price of the printer before the discount, we need to understand that the sale price represents 100% - the discount percentage of the original price. Given that the sale price is $59 after a 37% discount, we set up an equation where the original price (which we'll call P) minus 37% of P equals $59.

The equation looks like this: P - 0.37P = $59. We can simplify this equation by combining like terms, which gives us 0.63P = $59. To find P, we then divide both sides of the equation by 0.63, leading us to the original price.

Let's do the math:

The original price of the printer is calculated to be approximately $93.65.

Answer:

B. ΔABD, ΔADC, ΔDBC

Step-by-step explanation

Step -1 In ΔABD and ΔADC (from figure).

∠DAB=∠CAD (common in both triangles) ,

∠DBA=∠CDA =90 degree, and

∠BDA=∠DCA (rest angle of the two triangles).

therefore ΔABD similar to ΔADC (by AAA similarity theorem).

Step -2 In ΔDBC and ΔADC (from figure).

∠DCB=∠ACD (common in both triangles) ,

∠DBC=∠ADC =90 degree, and

∠CDB=∠CAD (rest angle of the two triangles).

therefore ΔDBC similar to ΔADC (by AAA similarity theorem).

Step -3 In ΔABD and ΔDBC (from figure).

∠BDA=∠BCD (because , ∠ACD=ADB from stap-1 and ∠ACD=∠BCD from figure) ,

∠DBA=∠CBD =90 degree, and

∠BAC=∠BDC (rest angle of the two triangles).

therefore ΔABD similar to ΔDBC (by AAA similarity theorem).

In the above step- ΔABD similar to ΔADC, ΔDBC similar to ΔADC and ΔABD similar to ΔDBC.

Hence ΔABD, ΔADC, ΔDBC similar to each other in the given figure.

Based on the diagram shown above, the three similar right triangles are: B. ΔABD, ΔADC, ΔDBC.

The Right Triangles Similarity Theorem states that when the altitude of a  triangle is drawn to the hypotenuse of a right angled triangle, then, the two triangles that are formed would be similar to each other, as well as the original triangle.

Based on triangles ABD and ADC, we can logically deduce the following congruent angles;

m∠DAB ≅ m∠CAD

m∠DBA ≅ m∠CDA = 90°

m∠BDA ≅ m∠DCA

ΔABD ~ ΔADC (AAA similarity theorem).

Based on triangles DBC and ADC, we can logically deduce the following congruent angles;

m∠DCB ≅ m∠ACD

m∠DBC ≅ m∠ADC = 90°

Answer:

C

Step-by-step explanation:

The measure of angle BC of the triangle is given by BC = 130°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔBCD , where it is isosceles

And , the measure of BC ≅ BD

where Isosceles triangle C B D has points on the circle.

The measure of arc CD = 100°

Now , arc length is twice the inscribed angle.

2 x ∠B = CD

2 x ∠B = 100

∠B = 100/2

∠B = 50

Now, in an isosceles triangle, the angle opposite to the equal sides must be equal.

The sum of the three angles must be 180.

x + x + 50 = 180°

2x = 180 - 150

2x = 130°

Hence , the measure of angle BC = 130°

Final answer:

The explicit formula for the sequence 2, 6, 18, 54, 162, ... is [tex]an = 2 imes 3^(n-1),[/tex] where an represents the nth term of the sequence.

Explanation:

The sequence given is 2, 6, 18, 54, 162, ..., which can be recognized as a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio (r). To find the explicit formula for the nth term of a geometric sequence, we use the formula an = a1  imes r(n-1), where a1 is the first term and r is the common ratio.

Looking at our sequence, the first term a1 is 2. The common ratio r can be found by dividing the second term by the first term (or any term by the previous term), which is 6/2 = 3. Now that we have both the first term and the common ratio, we can plug these values into our formula to get the explicit formula for the nth term of the sequence: an = 2  imes 3(n-1).

Final answer:

The function f(x) = 2x^3 – x^2 – 6x is found by factoring the function, resulting in the zeros at x = 0, x = -3/2, and x = 2.

Explanation:

To find the zeros of the function f(x) = 2x^3 – x^2 – 6x, we must set the function equal to zero and solve for x. If possible, this can be done by factoring the function or using synthetic division. In this case, the function can be factored by taking out a common factor of x:

f(x) = x(2x^2 - x - 6) = 0

Next, we can factor the quadratic equation 2x^2 - x - 6 to find the remaining zeros:

2x^2 - x - 6 = (2x + 3)(x - 2)

This gives us the following zeros for the function:

x = 0

x = -3/2

x = 2

Therefore, f(x) has three zeros: 0, -1.5 (or -3/2), and 2.
