I need help with this ​

Mathematics
1 answer:
Korvikt [17]2 years ago
7 0

Answer:

D.

Step-by-step explanation:

According to converse of the Pythagorean Theorem, that if the square of the third side (longest side) of a triangle equals the sum of the other two shorter sides, therefore, the triangle formed must be a right triangle.

From the side lengths given, the following satisfies the Pythagorean triple:

5² + 12² = 13².

Therefore, the procedure to use to confirm the converse of the Pythagorean Theorem would be to draw the two shortest side, 5 cm and 12 cm, so that a right angle will be between them. The side measuring 13 cm should therefore fit in to form a right triangle.

A car travels 60 miles per hour, and a plane travels 15 miles per minute. How far does the car travel while the plane travels 60
lara [203]

Answer:

The car travels 40 miles while the plane travels 600 miles.

Step-by-step explanation:

This problem can be solved by rules of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

In this problem, all the measures have direct relationship.

The first step is knowing how much the plane travels in a hour.

The problem states that in a minute, the plane travels 15 miles. How much does it travel in 60 minutes.

1 minute - 15 miles

60 minutes - x miles

x = 60*15

x = 900 miles

In a hour, the plane travels 900 miles.

Then we need to know how long it takes for the plane to travel 600 miles.

1 hour - 900 miles

x hours - 600 miles

900x = 600

x = \frac{600}{900}

x = 0.667 hours = 40 minutes.

Finally, we discover how much the car travels in 40 minutes.

The problem states that in a hour(60 minutes), the car travels 60 miles, so:

60 miles - 60 minutes

x miles - 40 minutes

60x = 2400

x = \frac{2400}{60}

x = 40 miles.

The car travels 40 miles while the plane travels 600 miles.

What is the range of the given function?
bazaltina [42]

Answer:

C. y = -9, -3, 0, 5, 7

Step-by-step explanation:

The given function is represented by the set of ordered pairs

{(-2,0,) (-4, -3,) (2, -9,) (0,5,) (-5,7)}

The range of this function is the set of all the y-values.

The set of the y-values are:

{-9,-3,0,5,7}

Therefore the range is y = -9, -3, 0, 5, 7

The correct option is C
