plzz help me...tomorrow there is opt math test in my school...If I fail then i have to leave opt classes and go to eco....our teacher only taught trigonometry and I was absent 2 3 days due to sickness...plzz help me
Answer:
The steps are :
[tex] {tan}^{2} θ - {cot}^{2} θ = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]
[tex]RHS = {sec}^{2} θ(1 - {cot}^{2} θ)[/tex]
[tex]RHS = (1 + {tan}^{2} θ)(1 - \frac{1}{ {tan}^{2} θ} )[/tex]
[tex]RHS = (1 + {tan}^{2} θ)( \frac{ {tan}^{2}θ - 1}{ {tan}^{2} θ} )[/tex]
[tex]RHS = - \frac{(1 + {tan}^{2}θ)(1 - {tan}^{2} θ)}{ {tan}^{2} θ}[/tex]
[tex]RHS = - \frac{(1 - {tan}^{4} θ)}{ {tan}^{2} θ} [/tex]
[tex]RHS = \frac{ {tan}^{4} θ - 1}{ {tan}^{2}θ } [/tex]
[tex]RHS = {tan}^{2} θ - \frac{1}{ {tan}^{2}θ } [/tex]
[tex]RHS = {tan}^{2} θ - {cot}^{2} θ[/tex]
[tex]RHS = LHS (proven)[/tex]

Patrick leaned a 30-foot ladder against the side of a building. The
base of the ladder is 17 feet from the base of the building. The top of
the ladder is 11 feet from the top of the building. How tall is the
building? Provide an answer accurate to the nearest tenth of a foot.
The distance between the bottom of the ladder and the ground's surface is 24.7 feet.
Given that a is the ground, b is the building, and c is the ladder.
Also the ground is perpendicular to the building, the ladder, the building, and the ground form a right triangle.
Therefore, the Pythagorean theorem can be applied as follows:
c² = a² + b²
According to the information in the problem, c is 30 feet, b is 17 feet, and we solve for a as follows:
(30 ft)² = a² + (17 ft)²
900 ft² = a² ₊ 289 ft²
900 ft² ₋ 289 ft² = a²
611 ft² = a²
a² = 611 ft²
a = √611 ft²
a = 24.71
rounding off to nearest tenth, so a = 24.7
Hence the bottom of the ladder is 24.7 feet far away from the base of the ground.

Morgan throws a ball up into the air. The height of the ball above the ground, in feet, is modeled by the function h(t) = −16t 2 + 24t, where t represents the time, in seconds, since the ball was thrown. What is the appropriate domain for this situation?
Answer:
I will give you the link below to a PDF that one of my young friends made for someone who had this exact question.
Step-by-step explanation:
The appropriate domain for this situation is [tex]\{t : 0 \leq t \leq 1.5\ \& \: t \in \mathbb R \}[/tex] (that means t can be any real number and between 0 and 1.5 (both endpoints included)
What is domain and range of a function?Domain is the set of values for which the given function is defined.
Range is the set of all values which the given function can output.
For this case, we have only those values of 't' as appropriate value, which are from t = 0 till the time when ball hits the ground, since after that the height will be constantly 0, but the height function will give negative values which doesn't model the situation correctly.
Thus, those values of t for which the equation [tex]h(t) = -16t^2 + 24t[/tex] correctly models the real world situation are said to be appropriate values of domain of this function.
The time when the ball will reach the ground will be when the height will be 0, thus,:
[tex]0 = -16t^2 + 24t\\2t^2 - 3t = 0\\(2t-3)(t) = 0\\t = 0, t = 3/2 = 1.5 \: \rm sec[/tex]
The height is 0 when ball starts going up(t=0), and when t = 1.5 the ball reaches ground.
Thus, the appropriate domain for modelling the situation is values of t in the interval [0, 1.5] (both endpoints are inclusive, as shown by big bracket).

Write a linear function f with the values f(-1)=-3 and f(2)=6.
Answer:
y = 3x
Step-by-step explanation:
Equation of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are given the following values of the function: f(-1)=-3 and f(2)=6. The points are (-1,-3) and (2,6). The slope is:
[tex]\displaystyle m=\frac{6+3}{2+1}=\frac{9}{3}=3[/tex]
Now find the equation of the line using the second point:
y - 6 = 3 ( x - 2 )
Operating:
y - 6 = 3x - 6
Simplifying:
y = 3x

What does "how many times greater" mean in math? Like do you subtract, multiply, add, divide? Are there steps, I have to follow? Help lol
Answer:
multiplication
Step-by-step explanation:
cuz it says "times greater"
Answer:
It means how may times can the other variable fit into that variable, so you would divide.
- For example: Bob has 6 flowers in his basket, but Sally has only 2 flowers in her basket.
Q: How many times greater is Bob's basket of flowers than Sally's?
A: Bob's basket is 3 times greater than Sally's (bc 6/2 = 3, or 2 can fit into 6 three times)

The youth group at the church decided to plant geraniums and
daisies around the church grounds as a group project. Geraniums
in 6" pots cost $4 each and daisy plants cost $6 each. The youth
group spent $410 on 80 plants. How many geraniums and how many
daisy plants did the group buy?
Answer:
The youth group bought 35 geraniums and 45 daisy plants.
Step-by-step explanation:
We can solve this using a system of equations:
x + y = 80
4x + 6y = 410
X = Geraniums
Y = Daisies
First, let's solve for a variable in the first equation. I am going to solve for y in the first equation:
x + y = 80
y = -x + 80
Now that we have solved for y we can plug that back in to the 2nd equation:
4x + 6(-x + 80) = 410
4x - 6x + 480 = 410
-2x + 480 = 410
-2x = -70
x = 35
Now that we have found the amount of geraniums we can plug it back into the first equation and solve for y:
35 + y = 80
y = 45
Therefore the youth group bought 35 geraniums and 45 daisy plants.
Check:
(35) + (45) = 80
80 = 80
4(35) + 6(45) = 410
140 + 270 = 410
410 = 410

A book is marked down by 28 percent from an original price of $19.50. What is the new price?
Step-by-step explanation:
First find 28% of $19.50:
($19.50) / (100) × (28) = $5.46
Now minus the 285 from the original price:
($19.50) - ($5.46) = $14.04
