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:

B and E are the correct answers.

Step-by-step explanation:

By using the slope formula of y₂₋y₁ / x₂₋x₁ you can find out that the slope is ₋7/4.

Next pick a point to put into point-slope form.

Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope.

Substitute both points into the formula (separately) to get B and E as your answers.

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

which is the general form of the equation of circle

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.

Answer:

y = 2x - 1

Step-by-step explanation:

So we can use the formula Y2 - Y1 / X2 - X1

So 7- 3 = 4 and 4 - 2 is 2 and 4/2 is 2 so the slope is 2.

If we keep using the slope we can tell that the y intercept is 1.

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:

A. 1

Step-by-step explain

You put the number in order and it will be only the 6 from the 6-10.

The value that should be placed in the second column for the range 6-10 is 1. Thus, the correct option is A.

The frequency is the number of times an event happens. Therefore, frequency is the number of repetition of a digit or an event.

For the given data set 3, 12, 25, 2, 3, 6, 17, 17, 15, 13, 20, 12, 21, 18, 19. The frequency table can be made as,

1 - 5  ⇒  3

6 - 10  ⇒  1

11 - 15  ⇒  4

16 - 20  ⇒  5

21 - 25  ⇒  2

Hence, the value that should be placed in the second column for the range 6-10 is 1. Thus, the correct option is A.

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%

2) The parameters given are;

The number of ways Karla can choose her shorts =  6 ways

The number of ways Karla can choose her pair of sandals =  3 ways

The total combination of outfits Karla can make = 10 × 6 × 3 = 180 combinations

3) We have;

The number of permutations of 10 numbers taking 4 at a time is given as follows;

n!/(n-r)! = 10!/(10-4)! = 10!/6! = 5040 pin numbers can be chosen

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.

Number of possible outcomes

This question represent selection; i.e. selecting candidates for job positions;  

This question can be solved by using Permutations/Selection formula

Given that 3 man are to be selected from 14 men and 2 women from a total of 6 women

Let M represent Men and W represent Woman

Number of ways = M + W

Calculating M

[tex]M = nPr[/tex]

Substitute nPr with its formular

[tex]M = \frac{n!}{(n-r)!}[/tex]

Where n = 14 men and r = 3 applied

[tex]M = \frac{14!}{(14 - 3)!}[/tex]

[tex]M = \frac{14!}{11!}[/tex]

[tex]M = \frac{14*13*12*11!}{11!}[/tex]

[tex]M = 14*13*12[/tex]

[tex]M = 2184[/tex]

Calculating W

[tex]W = nPr[/tex]

Substitute nPr with its formula

[tex]W = \frac{n!}{(n-r)!}[/tex]

Where n = 6 men and r = 2 applied

[tex]W = \frac{6!}{(6-2)!}[/tex]

[tex]W = \frac{6!}{2!}[/tex]

[tex]W = \frac{6*5*4*3!}{2!}[/tex]

[tex]W = 6*5*4[/tex]

[tex]W = 120[/tex]

Recall that Number of ways = M + W

Number of Ways = 2184 + 123

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
