Answer:
x = 9.83
Step-by-step explanation:
Reference angle = 55°
Opposite = x
Hypotenuse = 12
Apply trigonometric function SOH:
Sin 55 = Opp/Hyp
Sin 55 = x/12
12 × Sin 55 = x
9.82982453 = x
x = 9.83 (nearest hundredth)

If f(x) = 3LX-2], what is f(5.9)? 9 10 11 12
Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9 , we have
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12
The value of the function f(5.9) will be 12. The correct option is D.
What is a function?In mathematics, a function is a rule that assigns a unique output value to each input value in a specified domain. A function is often denoted by a letter such as f, and we write f(x) to represent the output value associated with an input value x.
We know that the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.

If sally invests $400 into the Bank of Reyonds that offers her a 6% interest, compounded monthly, how much money will she have in the bank in 5 years?
Given:
Principal = $400
Rate of interest = 6% compounded monthly
Time = 5 years.
To find:
The amount in the bank after 5 years.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest, n is the number of time interest compounded in an year and t is the number of year.
Interest compounded monthly. So, [tex]n=12[/tex].
Putting [tex]P=400, r=0.06, n=12[/tex] and [tex]t=5[/tex], we get
[tex]A=400\left(1+\dfrac{0.06}{12}\right)^{12(5)}[/tex]
[tex]A=400\left(1+0.005 \right)^{60}[/tex]
[tex]A=400\left(1.005 \right)^{60}[/tex]
[tex]A\approx 539.54[/tex]
Therefore, the amount of money in the bank after 5 years is $539.54.

if m<AFC= 150°, what is m<CFD
Answer:
30
Step-by-step explanation:
These are djacent angles ( two angles that have the same vertex, share a side, and do not overlap) The 2 angles form a linear pair The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
If one angle is 150 then the other angle must be 30
150+30 = 180

from the top of the tower the angle of depression of a bottom of a pillar on the same surface of height is 20 metre is 60 degree. if the angle of depression from the top of the pillar to the bottom of a tower is 22 degree. find the height of the tower.
Answer:
85.74 m.
Step-by-step explanation:
tan 22 = 20/x where x is the distance between the tower and the pillar.
x = 20 tan 22 = 49.50.
tan 60 = h/49.50 where h is height of the tower
h = 49.5 tan 60
= 85.74 m.

Answer:
p = 1
Step-by-step explanation:
4 - 5(p + 3/5) = -4
Find P
4 - 5(p + 3/5) = -4
4 - 5p -15/5 = -4
4 - 5p - 3 = -4
-5p + 1 = -4
-5p = -4 - 1
-5p = -5
p = -5/-5
p = 1
Check:
4 - 5(p + 3/5) = -4
4 - 5(1 + 3/5) = -4
4 - 5 - 15/5 = -4
4 - 5 - 3 = -4
4 - 8 = -4
-4 = -4

Cho has sold 28 bags and his goal is to sell 100 bags write an inequality to show how many more bags he needs to sell
Answer:
x ≤ 72
He needs to sell 72 more bags.
Step-by-step explanation:
Cho has sold 28 bags and his goal is to sell 100 bags write an inequality to show how many more bags he needs to sell
Let x represent the number of bags he needs to sell
28 + x ≤ 100
x ≤ 100 - 28
x ≤ 72
Therefore he needs to sell 72 more bags.
156 people said they spent the night in Wal-Mart the night before Black Friday to get the good deals! This number represented 39% of the total number of shoppers at Wal-Mart. How many shoppers were at Wal-Mart?
Answer: 400 Shoppers
Step-by-step explanation:
Given
156 people spent the night in Wal-mart
These 156 people represent 39% of total shoppers at Wal-mart
Suppose x is the total no of shoppers at Wal-mart
So, we can write
[tex]\Rightarrow 39\%\ \text{of}\ x=156\\\Rightarrow 0.39\times x=156\\\\\Rightarrow x=\dfrac{156}{0.39}=400\ \text{People}[/tex]
