Answer:
The answer to your question is the second choice tan Ф = -3/4
Step-by-step explanation:
Data
sin Ф = -3/5
cos Ф > 0
Process
1.- The sin Ф is negative, which means that is in the third or fourth quadrant.
2.- sin Ф = -3/5 and sin Ф = Opposite side/hypotenuse
then, Opposite side = 3 hypotenuse = 5
3.- Calculate the adjacent side using the Pythagorean theorem
c² = a² + b²
b² = c² - a²
b² = 25 - 9
b² = 16
b = 4
4.- If cos Ф is in the third quadrant
cos Ф = -4/5 and cos Ф < 0 This is incorrect
5.- If cos Ф is in the fourth quadrant
cos Ф = 4/5 and cos Ф > 0 This is correct
Then, this angle is in the fourth quadrant
6.- Calculate tan Ф
tan Ф = -3/4
To solve this problem, there are a couple things we need to do. First of all, we need to figure out how much more she's running every day. On day 1, she ran 3/16 of a mile. On day 2, she ran 3/8 of a mile. On day 3, she ran 9/16 of a mile.
How much are we adding each time? To find that out, we need all of our fractions to have the same denominator so we can compare. Let's give 3/8 a denominator of 16. 8*2=16. What you do on one side of the fraction bar, you MUST do to the other: 3*2=6. So, 3/8 = 6/16.
Day 1: 3/16. Day 2: 6/16. Day 3: 9/16. Now do you see the pattern? Every day, she runs 3/16 of a mile more. That's the answer to part 1: 3/16.
So, how long will it take her to get over 1 mile? Let's continue. Day 3: 9/16. Day 4: 9+3=12, so that's 12/16. Day 5: 15/16. Day 6: 18/16! Since the numerator is bigger than the denominator, guess what? That's more than one mile!! So on the 6th time she runs, she ran 18/16 miles. Keep in mind that 18/16 = 9/8 = 1 1/8 miles.
Answers: 3/16; 6th; 1 1/8 (or 9/8)
Answer:
180=2^2×3^2×5
Step-by-step explanation:
We have to obtain the factors of 180 which are prime numbers
A prime number being a number with only 2 factors.That is 1 and the number itself.
For example 5 only has 2 factors 1 and 5⇒5=1×5
Here are the first few prime numbers
2,3,5,7,11,13,.....
A number which is not prime is a composite number. Composite numbers have more than 2 factors. All composite numbers can be expressed as a product of prime factors.
