tan of theta= -12/5 and it’s in quadrant 4
Find the exact values of sin theta/2 and the tan of theta/2
Answers
Answer:
sin θ/2 = ± √2/13
Step-by-step explanation:
tan θ = - 12/5 (in quadrant 4) sin θ = - 12/13 and cos θ = 5/13
sin θ/2 = ± (√1 - cos θ) / 2 = ± (√1 - 5/13) / 2 = ± √8/13 / 2 = ± √2/13
tan θ/2 = (1 - cos θ) / sin θ = sin θ / (1 + cos θ)
Let you to calculate the tan θ/2 part by yourself
The first, third and thirteenth terms of an arithmetic sequence are the first 3 terms of a geometric sequence. If the first term of both sequences is 1, determine:
1.) the first three terms of the geometric sequence if r > 1
2.) the sum of 7 terms of the geometric sequence if the sequence is 1, 5, 25
Answers
Answer:
The first three terms of the geometry sequence would be [tex]1[/tex], [tex]5[/tex], and [tex]25[/tex].
The sum of the first seven terms of the geometric sequence would be [tex]127[/tex].
Step-by-step explanation:
1.Let [tex]d[/tex] denote the common difference of the arithmetic sequence.
Let [tex]a_1[/tex] denote the first term of the arithmetic sequence. The expression for the [tex]n[/tex]th term of this sequence (where [tex]n\![/tex] is a positive whole number) would be [tex](a_1 + (n - 1)\, d)[/tex].
The question states that the first term of this arithmetic sequence is [tex]a_1 = 1[/tex]. Hence:
The third term of this arithmetic sequence would be [tex]a_1 + (3 - 1)\, d = 1 + 2\, d[/tex]. The thirteenth term of would be [tex]a_1 + (13 - 1)\, d = 1 + 12\, d[/tex].The common ratio of a geometric sequence is ratio between consecutive terms of that sequence. Let [tex]r[/tex] denote the ratio of the geometric sequence in this question.
Ratio between the second term and the first term of the geometric sequence:
[tex]\displaystyle r = \frac{1 + 2\, d}{1} = 1 + 2\, d[/tex].
Ratio between the third term and the second term of the geometric sequence:
[tex]\displaystyle r = \frac{1 + 12\, d}{1 + 2\, d}[/tex].
Both [tex](1 + 2\, d)[/tex] and [tex]\left(\displaystyle \frac{1 + 12\, d}{1 + 2\, d}\right)[/tex] are expressions for [tex]r[/tex], the common ratio of this geometric sequence. Hence, equate these two expressions and solve for [tex]d[/tex], the common difference of this arithmetic sequence.
[tex]\displaystyle 1 + 2\, d = \frac{1 + 12\, d}{1 + 2\, d}[/tex].
[tex](1 + 2\, d)^{2} = 1 + 12\, d[/tex].
[tex]d = 2[/tex].
Hence, the first term, the third term, and the thirteenth term of the arithmetic sequence would be [tex]1[/tex], [tex](1 + (3 - 1) \times 2) = 5[/tex], and [tex](1 + (13 - 1) \times 2) = 25[/tex], respectively.
These three terms ([tex]1[/tex], [tex]5[/tex], and [tex]25[/tex], respectively) would correspond to the first three terms of the geometric sequence. Hence, the common ratio of this geometric sequence would be [tex]r = 25 /5 = 5[/tex].
2.Let [tex]a_1[/tex] and [tex]r[/tex] denote the first term and the common ratio of a geometric sequence. The sum of the first [tex]n[/tex] terms would be:
[tex]\displaystyle \frac{a_1 \, \left(1 - r^{n}\right)}{1 - r}[/tex].
For the geometric sequence in this question, [tex]a_1 = 1[/tex] and [tex]r = 25 / 5 = 5[/tex].
Hence, the sum of the first [tex]n = 7[/tex] terms of this geometric sequence would be:
[tex]\begin{aligned} & \frac{a_1 \, \left(1 - r^{n}\right)}{1 - r}\\ &= \frac{1 \times \left(1 - 2^{7}\right)}{1 - 2} \\ &= \frac{(1 - 128)}{(-1)} = 127 \end{aligned}[/tex].

Rohan bought an almirah for Rs 15,600 and spent Rs 400 on its transportation. The total C.P is __________
Answers
From the question,
Rohan bought an almirah for =Rs.13600= cost price
Transportation cost =Rs.400
The total cost price of almirah =Rs.(13600+400)
The total cost price of almirah =Rs.(13600+400)=Rs.14000
He sold it for =Rs.16800= selling price
By comparing SP and CP=SP>CP, so there is a gain
Gain=SP−CP
=16800−14000
=Rs.2800
Gain %={(gain/CP)×100}
={(2800/14000)×100}
={2800/140}

Surface area ⇒ area of 2 triangles + area of 3 rectangles
[tex](8 \times 3 \times 0.5 \times 2)+(20 \times 5 \times 2+20 \times 8)=384[/tex]
Answer:
Surface Area = 384 m²
Step-by-step explanation:
The given figure is a triangular prism.
The surface area of a triangular prism is made up of:
2 congruent triangles (the bases of the prism).3 rectangles.From inspection of the diagram, the dimensions of the triangular bases are:
Base = 8 mHeight = 3 m[tex]\boxed{\begin{aligned}\textsf{Area of a triangle}&=\dfrac{1}{2} \times \sf base \times height\\\\\implies \textsf{Area of triangular base}&=\dfrac{1}{2} \times 8 \times 3\\&=4 \times 3\\&=12\; \sf m^2 \end{aligned}}[/tex]
From inspection of the diagram, there are two congruent rectangles with dimensions:
Length = 20 mWidth = 5 mand one rectangle with dimensions:
Length = 20 mWidth = 8 m[tex]\boxed{\begin{aligned}\textsf{Area of a rectangle}&=\sf width \times length\\\\\implies \textsf{Area of rectangle 1}&=5 \times 20\\&=100\; \sf m^2 \\\\\implies \textsf{Area of rectangle 2}&=8 \times 20\\&=160\; \sf m^2\end{aligned}}[/tex]
Therefore, the total surface area of the given triangular prism is:
[tex]\begin{aligned}\textsf{Total Surface Area}&=\sf 2\;Triangles + 2\;Rectangle\;1+Rectangle\;2\\& = 2 \times 12+ 2 \times100+160\\& = 24+200+160\\& = 224+160\\& = 384\; \sf m^2\\\end{aligned}[/tex]

Consider the following pair of equations:
y = x + 4
y = −2x − 2
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. There is no pic pls help xd
Answers
Answer:
x is equal to -2, and y is equal to 2.
Step-by-step explanation:
You can solve this type of question by solving one of the equations for a given variable, and substituting it into another.
Because both of these are definitions of y, we could simply say, y = y, and thus:
x + 4 = -2x - 2
3x = -6
x = -2
This tells us also that y, being equal to x + 4, must equal 2
We can find the same solution by solving one of them for x, then substituting that into the other. We know:
y = x + 4
so we can also say:
x = y - 4
If we substitute that into the other:
y = -2x - 2
y = -2(y - 4) - 2
y = -2y + 8 -2
3y = 6
y = 2
which we can then plug into either of the original equations to solve for x:
y = x + 4
2 = x + 4
x = -2
When Jeremiah does 7 push-ups and 15 sit-ups, it takes a total of 66 seconds. In comparison, he needs 48 seconds to do 7 push-ups and 9 sit-ups. How long does it take Jeremiah to do each kind of exercise?
Answers
Answer:
3.43 seconds to do push ups and 2.66 seconds for him to do sit ups in the given time of 48 seconds ( to find the difference of time of each exercise done in the two different time, subtract each time unit from each other)
Step-by-step explanation:
for him to do 7 push ups and 15 sit ups in 66 seconds it would take time 4.71 second (5 seconds rounded) to do push ups. it would take him 2.20 seconds (2 seconds rounded) for him to do 15 sit ups in 66 seconds. for him to do it in 48 seconds, it would take him 3.43 (3 seconds rounded) to do 7 push ups in 48 seconds. for him to do 9 sit ups in 48 seconds it would take in 2.66 seconds ( 3 seconds rounded) for him to complete them in the given time.

Solve a0 = 0, a1 = 1 and an = an−1 + an−2 + 2n , for n ≥ 2. Hints: This one involves a lot more algebra than the problems above. Solving the homogeneous problem will involve using the quadratic formula. The characteristic roots turn out to be 1 ± √ 5 2 (but show the work!). For a particular solution, try an = A2 n . You should find A = 4 (but show the work!). Put those two pieces together to write down the general solution an = A( (1 + √ 5 )/2 )^n + B( (1 − √ 5)/ 2 )^n + 4(2^n ) and the determine the values for A and B by using the two initial conditions, a0 = 0 and a1 = 1. The necessary arithmetic will be somewhat complicated, but not impossible.

Answers
Answer:
Step-by-step explanation:
circumference of cylinder = πd = 5π in
lateral area of cylinder = 5π×9 = 45π in²
Each colored face has a matching face on the other side of the figure.
green areas = 2(17×15) = 510 in²
blue areas = 2(12×17) = 408 in²
gray areas = 2(5×6) = 60 in²
yellow areas = 2(5×12) = 120 in²
red areas = 2(12×15) = 360 in²
total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
