If the factored form of a quadratic is 4(x - 3)(2x + 5) = 0, what are the roots? A. 2,-3, and 5/2 B. 3 and -5/2 C. -3 and 2/5 D. - 3 and 5/2​

Answers

Answer:

B. 3 and -5/2

Step-by-step explanation:

The roots of a quadratic equation make the value of the equation equal to 0

Here, the equation is :

4(x - 3)(2x + 5) = 0

So, whatever values of x makes the equation 0 are the roots.

Hence,

x - 3 = 02x + 5 = 0

1st x value

x - 3 = 0x = 3

2nd x value

2x + 5 = 02x = -5x = -5/2

The roots are 3 and -5/2.

Do the angle measurements 70, 90, 75 make a triangle?

Answers

Answer:

Yes.

Step-by-step explanation:

Because the sum of any 2 sides is greater than the third side.

Interior angles of a triangle always add up to 180 degrees, so no.
90 degree is a right triangle and it would have two acute angles. An obtuse triangle would have one angle larger than 90 degrees and two acute angles. An acute triangle would have all angles smaller than 90 degrees.

Answer:

Ok

Step-by-step explanation:

Angle GPF = 180( straight angle) - 38 = 142.

Opposite angle HPG and EPG = 38

Angle DPE = 180 - 90 - 38 = 52.

This line is going up by two.

To find the range just count the space between the Maximum and Minimum.

Or subtract the Minimum from the Maximum.

For this, the Minimum is 32.

The Maximum is 56.

Now that we know, let's subtract.

56 - 32 = 24

At a swim meet, 8 different swimmers compete in the 800- meter freestyle race. How many different ways are there for these swimmers to finish

Answers

Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.

What is the arrangements formula?

The number of possible arrangements of n elements is given by the factorial of n, that is:

[tex]A_n = n![/tex]

In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:

[tex]A_8 = 8! = 40320[/tex]

The sum of five consecutive integers is 46 less than 9 times the least of the integers. Find the largest consecutive integer.
Question 6 options:

A)

17

B)

10

C)

18

D)

19

Answers

Answer:

  C)  18

Step-by-step explanation:

Let x represent the largest of the five consecutive integers. Then (x -4) is the smallest, and the sum of the five of them is ...

  sum = 5((x +(x -4))/2 = 5x -10

That sum is 46 less than 9 times the smallest.

__

This relation can be written as ...

  5x -10 = 9(x -4) -46

  72 = 4x . . . . . . . . . . . . add 82-5x and simplify

  18 = x . . . . . . . . . divide by 4

The largest of the consecutive integers is 18.

_____

Additional comment

Here, we have used the variable to represent what the problem is asking for--the largest of the integers. Often, in consecutive integer problems, it is convenient to let a variable represent the middle (or average) value of the consecutive integers. If we do that here, then sum of the 5 integers would be 5x, and the relation to find x would be ...

  5x +46 = 9(x -2)

This resolves to 64=4x ⇒ x=16, so the largest integer is x+2=18. The number of steps is about the same, but the sum is easier to find, and there aren't as many constant terms to play with in solving for x.

Find a fraction that is more than 0 and less than 1/1000

Answers

Answer:

Any of these are correct:

1/1001, 1/1002, 1/1003

1/10000

2/3000= 1/1500

3/4000

so many!

Step-by-step explanation:

Anything that is positive and not negative will be bigger than zero.

Anything with a 1 on top (numerator) and LARGER than 1000 on the bottom (denominator) will be less than 1/1000.

OR you can change 1/1000 by multiplying 2/2 or 3/3 or 4/4 or 5/5 etc. Then lower the top number only. Example:

1/1000 × 5/5 = 5/5000

6x = 150 (Subtract 30 from both sides)

x = 25 (Divide both sides by 6)

m<RQS = 4(25) + 3

Work out the angle under

Answers

The value of two inner angle other than x can be find out by subtracting 130° and 96° from 180° differently , because a straight line always make an angle of 180°

So ,

180° - 130° = 50 °

180° - 96° = 84°

Therefore , 50° and 84° are the two internal angle other than x

To find x ,

as the sum of all angles inside a triangle is 180°

50° + 84° + x = 180°

x = 180° - 134°

x = 46°
