Answers

Answer:

∠ RQS = 138°

Step-by-step explanation:

Since PR and PS are tangents to the circle, then

∠ QRP = ∠ QSP = 90°

The sum of the interior angles of PRQS = 360°

Subtract the sum of the interior angles from 360° for ∠ RQS

∠ RQS = 360° - (90 + 90 + 42)° = 360° - 222° = 138°

Zahra runs a 500-meter race at a constant speed. Which graph shows her distance from the finish line during the race?

Answers

Answer: The answer is the third figure. Attached the image.

Step-by-step explanation: Given that Zahra runs a 500-meter race at a constant speed. We are to select the correct graph from the four options that will show her distance from the finish line during the race.

We can see in graph 2, the distance covered by Zahra in metres increases at the same rate as the time increases in minutes.

But, since we are considering from the finish line, so option (#) will be right, because Zahra starts at 500 metres, decreases in the same manner as the increase of time and goes down to 0 on the positive X-axis.

Also,

Thus, the attached graph, which is the third option is the correct graph.

a. 4,669,920
b. 311,875,200
c. 154,440
d. 6,497,400

Answer:

Step-by-step explanation:

The possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .

What is permutation?

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol [tex]P_{r} ^{n}[/tex] is used to denote the number of permutations of n distinct objects, taken r at a time.

Formula of permutation

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

According to the question

Remove all of the hearts from a normal deck of cards.

i.e,

Total normal deck of cards = 52

On Removing hearts cards(n) = 13  

Now, with this new hearts-only deck, how many possible five-card hands can you draw .

Card to draw (r)= 5

Applying formula of  permutation

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

n = 13

r = 5

Substituting the values

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13!)}{(13-5)!}[/tex]

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13*12*11*10*9*8!)}{(8)!}[/tex]

[tex]P_{r} ^{n}[/tex] = 15,4440

Hence, the possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .
