Answer:
37) m∠x = 5.25
39) m∠x = 0.5236 and m∠x = 2.62
Step-by-step explanation:
37)
∵ cotx = -0.6 and 3π/2 ≤ x ≤ 2π
∴ tanx = -1/0.6
∵ ∠ x in the fourth quadrant ⇒ ∴ m∠x = 2π - α where α is an acute angle
∵ tanα = 1/0.6 ⇒ α =
∴ α = 1.03038
∴ m∠x = 2π - 1.03038 = 5.25
39)
∵ cscx = 2 and 0 ≤ x ≤ 2π
∴ sinx = 1/2 ⇒ +ve value
∴ ∠x is in the first quadrant or the second quadrant
∴ m∠x = α or m∠x = π - α
∵ sinα = 1/2 ⇒ ∴ α =
∴ α = 0.5236
∴ m∠x = 0.5236
∴ m∠x = π - 0.5236 = 2.6216 ≅ 2.62
Answer:
<h2>brainiest me</h2>
Step-by-step explanation:
The value returned is TRUE if all of the values in x are TRUE (including if there are no values), and FALSE if at least one of the values in x is FALSE. Otherwise the value is NA (which can only occur if na.rm = FALSE and ... contains no FALSE values and at least one NA value).
Answer:
A=0.51
B=0.73
C=0.41
D=A student taking algebra II is dependent on whether they prefer it and a student being in 10th grade is dependent on their age
Step-by-step explanation:
These answers are all in fractions btw
A)5/255+20/245+65/225+90/725=0.514267 which rounds to 0.51
B)100+65=165
165/225=0.73
C)100/245=0.41
Hope it helps !
