Answer:
The answer is below
Step-by-step explanation:
Trigonometric functions are functions used in right angled triangles to relate an angle in the triangle to the ratio of two side. The most common trigonometric functions are the sine, the cosine, and the tangent.
Some trigonometric identities are:
secθ = 1/ cosθ, cosecθ = 1 / sinθ, tanθ = sinθ / cosθ, cotθ = 1 / tanθ = cosθ / sinθ.
Hence simplifying the question:
[tex]\frac{sin\theta}{cos\theta tan\theta} =\frac{sin\theta}{cos\theta *\frac{sin\theta}{cos\theta} }\\\\=\frac{sin\theta}{sin\theta}\\\\=1[/tex]

Help me to solve chart
Answer:
Here,
the given expression is:
3x-15
when x=1
then
=3×1-15
=3-15
=-12
when x=2
then
=3×2-15
=6-15
=9
when x=3
then
=3×3-15
=9-15
=6
the value of x in expression 3x-15 is -12,9 and 6.
Answer:
1 = (3 x 1) - 15
2= (3 x 2)- 15
3= (3 x 3)- 15
Step-by-step explanation:
1= -12
2= 9
3= 6
Mary wants to buy 8 pounds of
grapes. Each pound costs $1.89.
Mary has $15. Does she have enough
money to buy the grapes? Explain.
Answer:
No, he does not have enough money to buy the grapes because he only has 15$ when in total the the grapes are $28.35.

A 22 km walk is completed in 5 hours and 30 min.
What is the average speed?
Answer:
121 km\hr
Step-by-step explanation:
displacement=speed÷time
then. speed = displacement×time
= 22 × 5.5
= 121 km\hr
write the equation for the line in slope-intercept form (2,-3) (-1/2) ( HELP PLEASE )
Answer:
A linear equation is a fancy term for a straight line, which can be created by joining 2 points.
A point can be defined by (x, y), where x and y are the horizontal distance and the vertical distance respectively from point (0,0) (called the origin).
There are 3 ways to define a line:
(1) The slope-intercept form
y = mx + b, in which m is the slope, b is the y-intercept, where the line crosses the vertical axis at (0, b). If values of m and b are given, you can substitute and write the equation right away.
The slope, m, is calculated by rise (vertical difference between 2 points on the line) divided by run (horizontal difference between the 2 points on the line)
Step-by-step explanation:
or example, if 2 points on the line are
(x1, y1) and (x2, y2)
Then slope = (y1– y2)/(x1 — x2)
If m > 0, then the line rises to the right.
If m = 0, then the line is horizontal.
If m < 0, then the line rises to the left.
If the line is in the form x = c, where c is a constant, then the line is vertical.
(2) Point slope form
m = (y — y1)/(x — x1), when (x1, y1) and m are given.
In other words,
m(x — x1) = y — y1
mx — m(x1) = y — y1
y = mx — m(x1) + (y1)
Note that b = -m(x1) + (y1)
(3) linear form
ax + by + c = 0, where a, b, and c are constants.

Answer:
y = 30200
x = -29950
Step-by-step explanation:
1.)
Let x represent children and y for adults.
200x + 450y = 7,600,000
x + y = 250
2.)
200x + 450y = 7,600,000
x + y = 250
-200(x + y = 250)
-200x + -200 = -50000
200x + 450y = 7,600,000
+ -200x + -200 = -50000
——————————————-
250y = 7550000
y = 30200
x + 30200 = 250
x = -29950
Uhm so I don’t know why for children I got a negative number? The wording for this question is very weird.

Step-by-step explanation:
Greg’s mother fills the tank of her car with gas on Saturday morning. She uses 1/4 of the tank on Saturday and another 2/5 of the tank on Sunday. How much gas remains in the gas tank?
Answer:
7/20
Step-by-step explanation:
You would do one whole tank minus how much she used on Saturday and minus how much of the tank she used on Sunday.
1-(1/4)-(2/5)=7/20
Inverse Trigonometry solve the questions below
Answer:
1. θ = 34.85°
2. x = 36.31°
3. x = 39.80°
Step-by-step explanation:
1. Determination of θ.
Adjacent = 11.9
Hypothenus = 14.5
Angle θ =?
Cos θ = Adjacent /Hypothenus
Cos θ = 11.9 / 14.5
Cos θ = 0.8207
Take the inverse of Cos
θ = Cos¯¹ 0.8207
θ = 34.85°
2. Determination of x
Opposite = 9 m
Hypothenus = 15.2 m
Angle x =?
Sine x = Opposite /Hypothenus
Sine x = 9 / 15.2
Sine x = 0.5921
Take the inverse of Sine
x = Sine¯¹ 0.5921
x = 36.31°
3. Determination of x
Opposite = 10 in
Adjacent = 12 in
Angle x =?
Tan x = Opposite / Adjacent
Tan x = 10 / 12
Tan x = 0.8333
Take the inverse of Tan
x = Tan¯¹ 0.8333
x = 39.80°

Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25
A broker charges customers a fixed fee of 150 plus 5.50% of the amount of all investments made. If a customer invests £40000 through the broker what is the total brokerage payable.
Answer:
£2350
Step-by-step explanation:
Commission on the £40,000 = 0.055 x £40000 = £2,200
Total brokerage payable = £2,200 + £150 = £2350

You flip a fair coin 8 times in a row. What is the probability that it will land on tails every single time? Write the answer as a fraction.
Answer:
50/100 chance
Step-by-step explanation:
It would be a 50/50 chance, because the coin has two sides, so it's a 50/50 chance that it'll land on tails all 8 times.
