Answer:

A = 60 cm²

Step-by-step explanation:

Finding BC using Pythagorean Theorem:

=> [tex]c^2= a^2+b^2[/tex]

=> [tex]13^2 = a^2+5^2[/tex]

=> 169-25 = [tex]a^2[/tex]

=> [tex]a^2[/tex] = 144

Taking sqrt on both sides

=> BC = 12

So,

BC = CD = 12

=> BD = BC+CD

=> BD = 12+12

=> BD = 24

Now, The area:

=> Area of a Triangle = [tex]\frac{1}{2} (Base)(Height)[/tex]

Where BASE = 24, HEIGHT = 5

=> A = 1/2(5)(24)

=> A = 1/2(120)

=> A = 60 cm²

Step-by-step explanation IN triangle abc,

AC² = AB² + BC² (Phythogoras theorem)

13² = 5² + BC²

169 - 25 = BC²

144 = BC²

BC² = 144

BC = 12 (APPLAYING SQAURE ROOT)

Then in triangle ADC,

AD² = AC² + CD²

AD² = 13² + 12² (CD = BD - BC)

AD² = 169 + 144

AD = 17cm (aprox.)

Therefore area of triangle abd = 1/2× length × side = 1/2× 5 ×24 = 5 × 12 = 60cm

Answer:

2 and 6

Step-by-step explanation:

Well if the are is 12ft^2 and the perimeter is 16 ft then the length is 6 ft and the width is 2 ft.

So 6+6+2+2=16

6*2 is 12

Answer:

Step-by-step explanation:

hello,

we can assume that the table is a rectangle

so let's note x , y its length and width, we can write

(1 ) 2(x+y)=16

(2) xy=12

x and y are different from 0 and from (2) we can write

y =12/x we replace it in (1)

x+12/x=16/2=8

[tex]<=> x^2+12=8x\\<=> x^2-8x+12 = 0\\<=> x^2 -2x-6x+12=0\\<=> x(x-2)-6(x-2)=0\\<=> (x-6)(x-2)=0\\<=> x = 6 \ \ or \ \ x=2[/tex]

for x = 6 y = 2

for x = 2 y = 6

so the dimensions of the table is 2ft x 6ft

hope this helps

Answer:

4

Step-by-step explanation:

Answer:

option C.

G = {1, 2, 3}

H = {2, 4, 9}

1 = {4, 5, 6}

Step-by-step explanation:

From the diagram given above, we obtained the following information:

1. G Intercession H (G n H) has members i.e (G n H) is not epmty

G n H ≠ empty.

2. H Intercession I (H n I) has members i.e (H n I) is not empty

H n I ≠ empty.

3. G Intercession I (G n I) is empty i.e

G n I = empty.

Please note: Intercession of sets talks about elements or members common to the sets.

With the above information, we can suggest the answer to the question as follow:

For option A:

G = {odd numbers} = {1, 3, 5, 7,.. }

H = {even numbers} = {2, 4, 6, 8,.. }

I = {prime numbers} = {2, 3, 5, 7,...}

Therefore:

G n H = {} = empty

H n I = {2}

G n I = {3, 5, 7,..}

For option B:

G = {a,b,c}

H = {d, e, f}

I = {a, d, g}

Therefore:

G n H = {} = empty

H n I = {d}

G n I = {a}

For option C:

G = {1, 2, 3}

H = {2, 4, 9}

I = {4, 5, 6}

Therefore:

G n H = {2}

H n I = {4}

G n I = {} = empty

For option D:

G = {a, -13, 7}

H = {-13, -15, s}

I = {s, a, 23}

Therefore:

G n H = {-13}

H n I = {s}

G n I = {a}

From the above illustrations, only option C is correct.

Answer:

1) The probability that a person who tests positive actually has the disease is 0.1056 or 10.56%

2) 180 combinations

3) 5040 pin numbers can be chosen

4) 54439560 ways

5) 389283935040 ways

Step-by-step explanation:

1) From Bayes' theorem, we have;

[tex]P(A\mid B) = \dfrac{P(A)P(B\mid A)}{P(A)P(B\mid A)+P\left (\overline{A} \right )P\left (B\mid \overline{A} \right )}[/tex]

Where:

[tex]P(A\mid B)[/tex] = Percentage of the population that tests positive for the disease that actually have the disease

P(A) = Incidence rate = 0.5% = 0.005

[tex]P(B\mid A)[/tex] = Percentage of the population that have the disease and will tests positive = 1 - 0.06 = 0.94

[tex]P\left (\overline{A} \right )[/tex] = P(no disease) = 1 - 0.005 = 0.995

[tex]P\left (B\mid \overline{A} \right )}[/tex] = P(positive [tex]\mid[/tex] no disease) = False positive = 0.04

From which we have;

[tex]P(A\mid B) = \dfrac{0.005 \times 0.94}{0.005 \times 0.94 +0.995 \times0.04} = 0.1056[/tex]

Therefore, the probability that a person who tests positive actually has the disease = 0.1056 or 10.56%

Option C. Substitute -x for x and simplify f(-x)

Step-by-step explanation:

The rule for reflection over y axis is:

Substitute -x for x and simplify f(-x)

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given:

While reflecting a point with coordinates as (x, y), over y axis, the rule followed is

(x, y) = (-x, y)

The given function is,

f(x) = x²

So, reflecting it over y axis, we have to replace x with -x

(x, f(x)) = (-x , f(x))

So, the new reflected function is

f(-x) = -x²

Answer:

The correct option is A

Step-by-step explanation:

The standard form of equation of circle is written as:

(x - a)² + (y - b)² = r²

Where centers is given as (a,b)

The equation of the circle given in the question is:

x² + y² = 7

If the circle is translated T(-8,4), it means that the centre of translated circle lies at (-8,4).

So standard form of equation of circle is:

(x + 8)² + (y - 4)² = 7

Simplifying the equation:

(x² + 64 + 2(x)(8)) + (y² + 16 - 2(y)(4)) = 7

x² + 64 + 16x + y² + 16 - 8y = 7

x² + y² + 16x - 8y + 80 = 7

x² + y² + 16x - 8y + 80 - 7 = 0

x² + y² + 16x - 8y + 73 = 0

Answer:

C. 9.6 cm

Step-by-step explanation:

This is all about unit rate. In this scenario the unit rate is 50/1 and for 480 km that fraction would be 480/x so we could either do cross multiplication or divide across the numerator and denominators.  Let's divide. 480/50 is equal to 9.6. Seeing as that is what helped us get from numerator a to numerator b we would then multiply that in our denominators. So, 1*9.6 is equal to 9.6 so the amount of cm for 480 km is 9.6 cm.

Answer:

$5000

Step-by-step explanation:

Hours until midnight = 3 1/2

Hours until 1am = 1

3 1/2 x 1000 = 3500 = $3500

1 = ( 1000 x 0.50 = 500 (+1000) ) = 1500= $1500

3500+1500 = $5000

Answer:

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Step-by-step explanation:

In a triangle, the sum of all inside angles must be 180 degrees.

In this question:

The inside angles are: x, x + 50 and 180 - 3x.

Then

x + x + 50 + 180 - 3x = 180

2x - 3x = -50

x = 50

So

x degrees = 50 degrees.

x + 50 degrees = 50  + 50 = 100 degrees

(180 - 3x) degrees = (180 - 3*50) = 30 degrees.

Answer:

-15,20

Step-by-step explanation:

I do not know how to explain how I did it lol :) , but I am very sure that it is correct.

I hope this help you :)

Answer:

-15, 20

Explanation:

To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.

Take a look at the sequence given:

5, -5, 10, -10, 15,...

Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.

5 - first term

-5 - second term

5 ? ? = -5

5 × -1 = -5

So, this means the sequence multiplied negative one by the first term to get the second term. Therefore, the pattern should be 'multiply negative one' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.

5, -5, 10, -10, 15,...

5 × -1 = -5 [correct; provides the next term]

-5 × -1 = 5 [incorrect; does not provide the next term]

10 × -1 = -10 [correct; provides the next term]

-10 × -1 = 10 [incorrect; does not provide the next term]

According to the calculations shown above, the pattern we have identified ('multiply negative one') only works on every other term. Therefore, we must figure out the rest of the pattern for the remaining terms. To do that, identify what basic operation and number must be applied.

-5 - second term

10 - third term

-5 ? ? = 10

-5 × -2 = 10

So, this means the sequence multiplies negative two every other term. Therefore, the pattern should be:

multiply by negative one, multiply by negative two

However, to be sure the pattern we have identified is correct, apply it to the sequence.

5 × -1 = -5 [correct; provides the next term]

-5 × -2 = 10 [correct; provides the next term]

10 × -1 = -10 [correct; provides the next term]

-10 × -2 = 15 [correct; provides the next term]

Now that we have identified the correct pattern, let's apply it to the last term to find the next two terms.

5, -5, 10, -10, 15....

15 × -1 = -15

-15 × -2 = 20

Therefore, the next two terms in the sequence is -15, 20.

A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.

Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.

The volume of a right triangular prism is derived as follows;

Volume = 1/2 * b * h * l

Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.

Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;

(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.

Volume = 1/2 * 7 * 9 * 6

Volume = 189 cubic metres

(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.

Volume = 1/2 * 6 * 13 * 5

Volume = 165 cubic metres

(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.

Volume = 1/2 * 11 * 8 * 8

Volume = 352 cubic metres

(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.

Volume = 1/2 * 10 * 9 * 8

Volume = 360 cubic metres
