Which is true about the triangles’ perimeters?
2 triangles labeled Triangle A and Triangle B.
Triangle A has 3 sides, each labeled 9 kilometers.
Triangle B's base is labeled 15 kilometers. Its other 2 sides are each labeled 8 kilometers.
The perimeter of Triangle A is equal to the perimeter of Triangle B. The perimeter of Triangle A is 3 kilometers less than the perimeter of Triangle B. The perimeter of Triangle A is 4 kilometers less than the perimeter of Triangle B. The perimeter of Triangle A is 9 kilometers less than the perimeter of Triangle B.

Answers

Answer:

Step-by-step explanation:

let x be the common ratio / or scale factor

the sides of the triangle are

5x, 12x and 13x

sum of the sides defines perimeter

that is

5x + 12x + 13x = 15

30x = 15

x = 15/30

x = 0.5

The sides of the triangle are 0.5(5) = 2.5

0.5(12)=6

0.5(13) = 6.5

2.5, 6, 6.5 all in inches

f(x) = 3r2 + 12x + 5
What is the value of the discriminant of f?
D
How many distinct real number zeros does
f(x) have?

Answers

Answer:

The value of the discriminant is 84.

i.e. b²- 4ac = 84

b²- 4ac > 0

Therefore, there are two distinct real number zeros.

Step-by-step explanation:

We know that the discriminant of the quadratic equation ax²+bx+c=0 is equal to b²- 4ac.

We also know that:

When b²- 4ac = 0 there is one real root.When b²- 4ac > 0 there are two real roots.When b²- 4ac < 0 there are two complex roots.

We are given

f(x) = 3x² + 12x + 5

comparing with the quadratic function ax²+bx+c=0

a = 3, b = 12, c = 5

Discriminant = b²- 4ac

= (12)²-4(3)(5) ∵ a = 3, b = 12, c = 5

= 144 - 60

= 84

Thus, the value of the discriminant is: 84

b²- 4ac > 0

Therefore, there are two distinct real number zeros.

What is the value of x

Answers

Answer:

x=23.1822

Step-by-step explanation:

Since x is adjacent to the angle, and 24 is the hypotenuse, you use cosine. The equation would be cos(15)=x/24, which you cross multiply to make it x=24(cos(15)). 24(cos(15))=23.1822

Q5. Asif is 5 years younger than Qasim. Four years later, Qasim will be twice as old as
Asif. Find their present ages.

Answers

Answer:

Age of Qasim = 6 year

Age of Asif = 1 year

Step-by-step explanation:

Let :

Age of Qasim = x

Age of Asif = x -5

After 4 years there age will be:

Age of Qasim = x+4

Age of Asif = x-5+4 = x-1

We are given: Four years later, Qasim will be twice as old as Asif.

Age of Qasim = 2 (Age of Asif)

x+4=2(x-1)

x+4=2x-2

2x-x=4+2

x=6

So, We get x = 6

The present ages will be:

Age of Qasim = x = 6 year

Age of Asif = x -5 = 6-5 = 1 year

2. Simplify -9-15 to -24.

[tex] - 24 = 6m[/tex]

3. Divide both sides by 6.
