Given the quadrant of theta in standard position and a trigonometric function value of theta , find the exact value for the indicated function. I, cos theta = 0.25; tan theta
Answer:
[tex]\sqrt{15}[/tex]
Step-by-step explanation:
[tex]\cos(\theta)=\frac{1}{4}[/tex] is given.
My attempt will to be to use the Pythagorean Identity:
[tex]\cos^2(\theta)+\sin^2(\theta)=1[/tex]
[tex](\frac{1}{4})^2+\sin^2(\theta)=1[/tex]
[tex]\frac{1}{16}+\sin^2(\theta)=1[/tex]
Subtract 1/16 on both sides:
[tex]\sin^2(\theta)=\frac{15}{16}[/tex]
We have the following quotient identity:
[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\tan^2(\theta)[/tex]
[tex]\frac{\sin^2(\theta)}{\cos^2(\theta)}=\frac{\frac{15}{16}}{\frac{1}{16}}[/tex]
Multiply the numerator and denominator by 16. This is multiplying the fraction by 1 so this doesn't change the value of the fraction.
[tex]\tan^2(\theta)=\frac{15}{1}[/tex]
[tex]\tan^2(\theta)=15[/tex]
Square root both sides:
[tex]\tan(\theta)=\pm \sqrt{15}[/tex]
Since we are in the first quadrant then all 6 trigonometric functions are positive there so the answer is [tex]\sqrt{15}[/tex].

When Lucy was one month old her grandparents put $25
into a safety deposit box. The next month they put $30,
followed by $35 the month after that. They continued
adding money like this, each month adding $5 more than
the previous month. Her grandparents told her they would
continue doing so until her 18th birthday, at which point
she could use the money to attend college.
a) How much was added into the deposit box on
Lucy’s 10th birthday?
b) How much was added for the final deposit on
Lucy’s 18th birthday?
And
Luke’s father has told him that if Luke walks around the
neighborhood for a whole day to pick up trash then he will
pay him for doing so. He will pay Luke $0.20 for the first
piece and increase the pay by 5% for each piece after that.
This way Luke will get paid more for the pieces that are
harder to find. (round answers to the nearest penny)
a) How much money will Luke be paid for his 100th
piece of trash?
b) If Luke picks up 150 pieces total, then what is the
payment he receives for that final piece?
And
Rewrite the series in summation notation and find the total sum.
-2+1+4+7+….+88
Answer: 95$
Step-by-step explanation:
First you have to add 25 +30 and then you get 55
So 55 dollars was added to Lucy deposit box on her 10th birthday
Now for her 18 birthday
You have to do 55+35and you get 90 then add 90+5 which is 95
So there was 95 dollars added in her deposit box on her 18 birthday
Michelle is having a poster printed from a picture that is 4 inches wide by 6 inches tall. The enlarged poster is 20 inches wide and 30 inches tall. Which proportion can be used to represent the picture sizes?
StartFraction 6 over 4 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 20 over 30 EndFraction
StartFraction 4 over 6 EndFraction = StartFraction 30 over 20 EndFraction
StartFraction 4 over 30 EndFraction = StartFraction 6 over 20 EndFraction
Answer:
The correct answer is:
Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]
Step-by-step explanation:
Given that
Width of picture = 4 inches
Length of picture = 6 inches
Now
Width of poster = 20 inches
Length of poster = 30 inches
The proportion of the picture will be:
[tex]\frac{width}{length} = \frac{4}{6}[/tex]
Similarly the proportion of poster can be written as:
[tex]\frac{width}{length} = \frac{20}{30}[/tex]
Both proportions when combined can be written as:
[tex]\frac{4}{6} = \frac{20}{30}[/tex]
Hence,
The correct answer is:
Option 2: [tex]\frac{4}{6} = \frac{20}{30}[/tex]
Answer:
B
Step-by-step explanation:
This is becuase 30 and 6 are both the inches in height so their units must line up same goes with 4 and 20 becuase they are the same unit they must line up accordingly in the equation.

Mary is five times as old as Fred. In three years Mary will be 4 times as old as Fred. Find their present ages?
ans
here let mary age be x and fred be y
1st equation
x= 5y
2nd equation
x+3 =4(y+3)
now from 1st equation putting value of x in equation 2
x+3 = 4y+12
5y+3 = 4y +12
y = 9
so fred is 9 and mary is 45
Austin is 69 years younger than Jamie. 3 years ago, Jamie's age was 4 times Austin's age. How old is Austin now?
Answer: 26 years old
Step-by-step explanation:
Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3Simplify the equations --> 4x-12=x+66Solve the equation: 3x-12=66 --> 3x=78 --> x=26This is the same as other age problems, just with the extra step of distributing the multiplication.

AC congruent to DF because AC = 13.5 in. and DF = 13.5 in, EF congruent to BC because EF = 12 in. and BC = 12 in., ∠C congruent to ∠F. The triangles ACB and DEF congruent by the SAS Triangle Congruence Theorem only when x = 7
Step-by-step explanation:
If two sides in a triangle congruent to two sides in other triangle and the including angles between the two sides are congruent in the triangles, then the two triangles are congruent by the SAS postulate of congruency
In the given figure
→ If ∠C ≅ ∠F
∵ m∠C = m∠F
∵ m ∠ C = (2x + 14)°
∵ m∠F = (4x)°
→ Equate them to find x
∴ 4x = 2x + 14
→ Subtract 2x from both sides
∴ 2x = 14
→ Divide both sides by 2
∴ x = 7
→ In Δs ABC and DEF
∵ AC congruent to DF because AC = 13.5 in. and DF = 13.5 in
∵ EF congruent to CB because EF = 12 in. and CB = 12 in.
∵ ∠C congruent to ∠F
∴ The triangles ACB and DEF congruent by the SAS Triangle Congruence
Theorem only when x = 7

solve x then find each angle measure
Answer:
(7x-32) + (5x-27) = 9x -8
Exterior angle of a triangle is equal to the sum of two opposite interior
on solving
12x-59 = 9x -8
12x-9x= 59 -8
3x = 51
x = 17
n0w
(7x-32) = 7*17- 32 = 87
(5x-27) = 5*17 - 27 = 58
9x -8 = 9*17 -8 = 145
Step-by-step explanation:
Answer:
x = 17
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
7x - 32 + 5x - 27 = 9x - 8 add like terms
12x - 59 = 9x - 8
12x - 9x = 59 - 8
3x = 51 divide both sides by 3
x = 17
measure of angle K 7x - 32 ➡ 7 × 17 - 32 = 87°
measure of angle J 5x - 27 ➡ 5 × 17 - 27 = 58°
measure of angle L 9x - 8 ➡ 9 × 17 - 8 = 145°
To the man and women who adopted a helpless child when she was brought to them;
To the teachers who never really cared and ignored my problems;To those who never cared, never spoke, probably never knew my name;To the one true friend, whose caring was the only thing that prevented this even from happening sooner; Do not weep for me, or mourn my passing. I say this not because I expect to be missed, but to allow those who truly did not care go on with their lives with a clean conscience and dry eyes. I know you don’t want to weep for me. So don’t. But I do ask you to listen to the final words of a young girl who has taken charge of her own destiny.Perhaps my parents might feel something inside which causes them to shed tears. They may pretend that it’s sorrow for their “loss”, but I hope it is something else. Perhaps sorrow for bringing a child into this world when they really didn’t have the time or desire to raise her. I wasn’t the product of love, born of a desire to prepare another human being to grow and lead the human race. I was merely the next acquisition, the next task, the next project on their list of things that bring significance.No child should be brought into this world for the mere purpose of being just another possession. Why can’t you accept the things that make other people different rather than insisting everyone conforms to your will?Sure, some did offer friendly gestures. Drew Wilson often would greet me and ask about my life. Not that I ever felt comfortable enough to tell her anything; I never trusted her enough to give her the chance. What was the purpose? You left me isolated and alone, and no words I could say can convey to you the suffering you caused. I could name names, but in doing so, I would do more now for you than you ever did for me in life.I do not know if what awaits me when I get down off this rope. Will there be a void? Or will I come face to face with God? I just don’t care anymore. If you’re anything like your people, I wouldn’t want to know you. You preached to love one another, yet I’ve felt everything except love from Christians. Even if I could know you were different, well, I still reject you. You have left your “followers” to treat people like me poorly. You have allowed so many of the people you “love”, including me, to suffer. So you want me to trust you with my life? I don’t want to spend eternity with a careless deity like you, or with the company you keep.As my final moments tick away, I wonder what impact these words will create. It depends first on this web site being found, as I doubt whether school administration will want such venom spoken publicly about their lack of caring. Still, the Internet is a remarkable place where even the least significant individual can be heard. Will anyone listen? Will anyone take action? Will students pause and pay attention to the hur*ing hearts around them? And even if they do, will it be a temporary salve for their egos, to convince themselves they’re really not bad people or will real change happen?My heart certainly goes out to my fellow outsiders. With me gone, some of you will certainly feel more of the pain and h*rt that I did. No one understands you. No one cares how your day is going. No one bothers to get to know you as anything more than a nerd, a geek, a loser. You can do nothing for their social status, save the occasional boost to the ego they get from putting you in your place. Some of you, like Chloe Strum, will find outlets in music. Some, like Matthew Ohlson, will have an escape in Dr*gs. Some, like Hailie Duncan, will live their lives pursuing unicorns that they will never, ever catch. I never had a talent to lose myself in, or a dream or unicorn to chase, and so I have taken the path most dreaded. Some of you may soon join me, and I look forward to welcoming a brother or sister to the land where you will never su*fer the loneliness and rejection that faces you now.Farewell forever. I am going to another place. Where, I do not know. But logic dictates that it can only be an improvement. Perhaps my passing will only prove a footnote in a school yearbook. Then again, perhaps the sacrifice of one might bring hope to others. If my d*ath makes life for one person a little more bearable, or a little more enlightened, do I really d*e in vain?“The needs of the many outweigh the needs of the few, or the one.”

1/4 (y + 24) = 32
Answer:
y = 104
Step-by-step explanation:
1/4y + 1/4(24) = 32
1/4y + 6 = 32
1/4y = 32-6
1/4y = 26
1/4y ×4 = 26 × 4
y = 104
-2, 1, 4, 7, 10
find next two term
The next two term is 13 and 16 respectively.
Step-by-step explanation:
here,
a1 = -2
a2 = 1
a3 = 4
a4 = 7
a5 = 10
So, d = a2 - a1 = 1 - (-2) = 3
= a3 - a2 = 4 - 1 = 3
Here, Common difference is same everywhere and the value of d is 3
Then,
To find 6th term of this sequence
a6 = a5 + d
= 10 + 3
a6 = 13
To find 7th term of this sequence
a7 = a6 + d
= 13 + 3
a7 = 16
Thus, The next two term is 13 and 16 respectively.
