4 0

Answer:

Neither

Step-by-step explanation:

The slope of PQ is -3.

The slope of RS is 3.

Parallel lines have the same slope. The slopes for perpendicular lines are the opposite of the reciprocal. PQ and RS are intersecting lines, but not parallel or perpendicular.

For every 13 birds born there are 2 animals born. There were 44 fewer birds born last month, so how many animals were born?
bagirrra123 [75]
For every thirteen birds born there are 2 animals. 
so
13:2 is your ratio

There are fewer than 44 birds, so x > 44
43/13 = 3.3, or 3 birds for every 2 animals
2 x 3 = 6

There are 6 animals that were born

What is the end behavior of f(x)=4x^4-3x^2?
galben [10]

Answer:

as x→∞, y→∞

as x→-∞, y→∞

Step-by-step explanation:

To tell what the end-behavior is, look at the x with highest exponent value in the function.

f(x) = 4x⁴ - 3x²

The highest power is x⁴.

Our highest exponent value is 4.

If the highest power is an even number, the end behavior is:

  as x→∞, y→∞

  as x→-∞, y→∞

this is always true. It's part of the rule for end-behavior.

The end behavior graph for an even power will look like the graph for x².

This is also always true. It will always look like this if the highest power is an even number.

Electromagnetic radiation is more common than you think. Radio andTV stations emit radio waves when they broadcast their program
gladu [14]

Answer:

a) They have different wavelengths.

b) They have different frequencies.

Step-by-step explanation:

Electromagnetic waves (EM waves) refer to waves carrying electromagnetic radiant energy which are propagated through vacuum or non-vacuum (material medium). They range from radio waves to gamma rays; they travel through space at the speed of light (about 300 million metres per second) and they are measured in photons.

The EM waves have the following characteristics:

1. They have different wavelengths

2. They have different frequencies

3. They travel at the speed of light independent of the medium of propagation (vacuum or material medium)

4. They do not require a media to be propagated

<u>Based on the explanation above, Options </u><u>a</u><u> (They have different wavelengths) and </u><u>b</u><u> (They have different frequencies) are the correct answers</u>

What is the greatest common factor of 42, 30, and 45​
Crank

Answer:

GCF = 3

Step-by-step explanation:

Express the numbers as a product of their primes.

42 = 2 × 3 + 7

30 = 2 × 3 × 5

45 = 3 × 3 × 5

Identify the prime factors common to all 3 numbers.

common prime factor = 3 , thus

GCF = 3
