First, tan(θ) = sin(θ) / cos(θ), so if cos(θ) = 3/5 > 0 and tan(θ) < 0, then it follows that sin(θ) < 0.
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Then
sin(θ) = -√(1 - cos²(θ)) = -4/5
and so
tan(θ) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(θ) = 1/cos(θ) = 5/3
csc(θ) = 1/sin(θ) = -5/4
cot(θ) = 1/tan(θ) = -3/4

2/3x - 7 < 9
help please
Answer:
x<24
*the answer will be incorrect if you meant 2/(3x) instead of (2/3)x
Step-by-step explanation:
First, add 7 to both sides of the inequality to get "2/3x<16." Then multiply both sides by 3 to get "2x<48." Finally, divide both sides by 2 to get "x<24"
Simplify (46)
Give your answer as a power of 4.

using 3.14 or 22/7. what is the circumference of these 3 circles.
Answer:
1) 6(3.14) = 18.84 in
2) 9(2)(3.14) = 56.52 cm
3) 1.5(3.14) = 4.71 ft
Is that right?
Please help
Answer:
yes x = 16
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
133 = x + 117 ( subtract 117 from both sides )
16 = x

Evaluate:
(15 +12) - 3 to the second power
Answer:
Step-by-step explanation: (15+12)-3^2 power ------> 27-3^2 power ----> 27-9 ----> equals 18
ANSWER:
18
SOLUTION:
(15+12) -3^2
(15+12) = 27
=27-3^2
=27- 9
=18
the lengths of the sides of a triangle are 2n, n^2 and n+5 for what value of n do these lengths not make a triangle ?
Answer:
Step-by-step explanation:
Try n = 2
2n = 4
n^2 = 4
n+5 = 7 That works. It will make a triangle since the 2 smallest numbers are bigger than 7
Try n = 3
2n = 6
n^2 = 9
n + 5 = 8 That works. Same reason as above.
n = 4
2n = 8
n^2 = 16
n + 5 = 9 That works. Same reason.
n = 5
2n = 10
n^2 = 25
n+5 = 10 Aha! That doesn't work. the two smaller numbers only = 20.
There are likely many numbers that don't work. I'll try one more
n = 6
2n = 12
n + 5 = 11
n^2 = 36 This won't work either. Same reason as n = 5.

A teacher lives 8 miles from school. She drives a 2015 Chevy Camaro that gets 19 miles per gallon of gas. How much fuel will she need to get TO AND FROM work for the week?
Answer:
Step-by-step explanation:
Technically we cannot solve this without knowing how many days a week that she works.
f=(16mi*d)(gal/19mi)
f=(16/19)d
We would have to assume that she works a certain amount of days. If we assume she works every day
f=7(16/19)=112/19, approximately 5.9 gal
for the table below, what is the range?
Answer:
second option

Step-by-step explanation:
2x + 8 = 14
2x = 6
x = 3
Answer:
3
Step-by-step explanation:
subtract 8 from both sides
then divide 2 from both sides to get x = 3

Answer: 0.9
Step-by-step explanation:
Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.4.
Independently, she then decides whether or not to buy a CD, with a probability of 0.3 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)
ANSWER = 0.58
Divide R2
848 in the ratio 3:5.
Answer:
1 = 3x = 3 x 356 = 1068
2 = 5x = 5 x 356 = 1780
Step-by-step explanation:
Rupees = 2848
3x + 5x = 2848
8x = 2848
x = 2848 / 8 = 356
1 = 3x = 3 x 356 = 1068
2 = 5x = 5 x 356 = 1780
