If sina-Cosa= o find coseca.​

Mathematics
1 answer:
oee [108]2 years ago
6 0

Answer:

cscα=√2

Step-by-step explanation:

Problem: If sinα-cosα=θ find cscα

Solution:

sinα-cosα=θ

sinα=cosα

sinα=sin(90-α)

If α<90, then:

α=90-α

2α=90

α=45°

sin(45°)

1/sin(45°)

csc(45°)

√2

Therefore, cscα=√2 if sinα-cosα=θ

If xy=0 what must be true about either x or y?
Anettt [7]

Answer:

D. either x or y must equal 0​

Step-by-step explanation:

Its given that xy = 0

Remember that product of two numbers can be zero only if:

Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.

So, if the product of x and y is equal to 0 there are two possibilities:

  • Both x and y are equal to 0
  • Either x or y must be equal to 0

Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.

Hence, the condition which has to be true in all cases for xy = 0 is:

D. either x or y must equal 0​

Monroe Reservoir, it cost $25 per hour plus $100 deposit to rent a pontoon boat. a. Write an equation that describes the cost c,
makkiz [27]
C = 25h + 100 ......renting for 2 hrs...sub in 2 for h
c = 25(2) + 100
c = 50 + 100
c = 150 <===

if u spend 325...so sub in 325 for c
325 = 25h + 100
325 - 100 = 25h
225 = 25h
225/25 = h
9 = h <=== it was rented for 9 hrs

Please help me!! This is math 7th grade
Musya8 [376]

Answer:

14) false

15) false

Step-by-step explanation:

14) 120% of a positive whole number is always greater than the number. If the number is 1, 120% of it would give us 1.2 which is greater than 1. However if the number is a negative whole number, 120% of it would give us a smaller number. Let's try -1. 120% of -1 would give us -1.2, which is smaller than -1. Hence the statement is false.

15) 0.5% of a number is 0.5/100 of the number so we should multiply the number by 5/1000. 5/100 is only 5% of the number. Hence the statement is also false.
