Answer:
csc theta = 5/4
Step-by-step explanation:
cos theta = 3/5
cos theta = adjacent side/ hypotenuse
Let adjacent side = 3 and the hypotenuse = 5
csc theta = hypotenuse/ opposite side
We need to find the opposite side
We know that this is a right triangle, so we can use the Pythagorean theorem
(adj)^2 + (opp)^2 = (hyp)^2
3^2 + (opp)^2 = 5^2
9+ (opp)^2 = 25
Subtract 9 from each side
9-9+ (opp)^2 = 25-9
(opp)^2 = 16
Take the square root of each side
sqrt( (opp)^2) = sqrt(16)
opp = 4
csc theta = hypotenuse/ opposite side = 5/4
Answer:
5 units
Step-by-step explanation:
Calculate the length using the distance formula
d =
with (x₁, y₁ ) = (B(- 3, - 2) and (x₂, y₂ ) = C(0, 2)
BC =

Answer:
y = -16.25
Step-by-step explanation:
It can also be written as
-8y = 26 * 5
-8y = 130
y = 130/-8 = - 65/4 = -16.25
Answer:
The ball will hit the floor after 3 seconds.
Step-by-step explanation:
Step-by-step explanation:
(a) 15% of $ 6000 = 5/100 × 600= &30
value after x years =$ 6000 -$ 30x
(b) value after 6 years = $ 600 - & 180 = $ 5820
