Answer:
sin x = -5/13
csc x = -13/5
sec x = 13/12
cot x = -12/5
tan x = -5/12
Step-by-step explanation:
**x is in quadrant iv because 3pi/2<x<2pi
if cos x=12/13, then 12 is the adjacent value and 13 is the hypotenuse value. to find sin, or opposite/hypotenuse, use the pythagorean identity. opposite=5 and hypotenuse is given as 13. & since it's in quad iv, the sine (or y) value is negative bc it's below the x axis. thus, sin x = -5/13csc is cosecant, or the reciprocal of sine. so csc x = -13/5sec is secant, or the reciprocal of cosine. so sec x = 13/12tan is opp/adj, so tan x = -5/12. it's negative bc tan is negative in quad ivcot is cotangent, or the reciprocal of tangent. so cot x = -12/5Answer:
8. sin x = -5/13
9. csc x = -13/5
10. sec x = 13/12
11. cot x = -12/5
12. tan x = -5/12
Step-by-step explanation:
The mnemonic SOH CAH TOA can help you with the sine and tangent. You need to rely on your memory (or notes) to find the reciprocal functions.
The dimensions are such that you can recognize this as a 5-12-13 right triangle. Or, you can use the Pythagorean theorem to find the third side from ... O = -√(H² -A²) = -√(169 -144) = -√25 = -5
The given quadrant tells you that O is negative.
__
8. Sin = Opposite/Hypotenuse
Here, the opposite is -5. The hypotenuse is always taken to be positive.
sin x = -5/13
__
9. Csc = 1/Sin
csc x = -13/5
__
10. Sec = 1/Cos
sec x = 13/12
__
11. Cot = 1/Tan = Adjacent/Opposite
cot x = 12/-5
cot x = -12/5
__
12. Tan = Opposite/Adjacent
tan x = -5/12
2×2×3×5 and 2×2×5×5 LCM=_____________=_____
60, 100 = 300
hope this helps
Answer:
Step-by-step explanation:
LCM - Least common multiple
2 * 2 * 3 * 5 = 2² * 3 * 5
2 * 2 * 5 * 5 = 2² * 5 * 3
LCM = 2² * 3 * 5
= 4 * 3 * 5
= 60

A: 49,
B: -49,
C: -1/49,
D: 1/49.
Answer:
Option B -49
Step-by-step explanation:
-(7^-3)(7^5)
-1/7^3×7^5
-7^2
-49
So option B is correct
Answer:
B
Step-by-step explanation:
-(7^-3) = -1/343
(7^5) = 16807
16807*-1/343 = -49

Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?
Answer:
Riley rakes 1/4 of the lawns per hour.
Step-by-step explanation:
It is given that,
Riley rakes 1/6 of a lawn in 2/3 hour.
We need to find how many lawns can Riley rake per hour.
In 2/3 hour Riley rakes 1/6 of a lawn
In 1 hour Riley rakes [tex]\dfrac{1}{6}\times \dfrac{3}{2}=0.25[/tex] = 1/4 of a lawn.
Hence, Riley rakes 1/4 of the lawns per hour.

A ball is shot upward such that its height (in feet) above the ground after t seconds is h(t) = -16t2 + 96t + 5. What is the ball's maximum height?
Answer:
149 feet
Step-by-step explanation:
you have a quadratic equation and you need to fid it's vertex because that is the max height
h(t)= -16t² +96t +5
the x coordinate of the vertex is x= -b/2a for f(x)= ax²+bx+c so in our case
x= [tex]\frac{-96}{2*(-16)}[/tex]= 3 , now we know that the vertex bbelongs to the graph so should verify the equation so we substitute t of the value of x=3 to find y
y= -16*3²+96*3+5= -144+288+5=149
the max height is the coordinate of y because it tels us how much it went up

Jada have a monthly budget for her cell phone bill last month she spent 120% of her budget and the bill was $60 what is Jada monthly budget
Assume that the budget is n.
Now we are given that 120% of the budget is equal to $60.
This means that:
60 = 1.2n
Solve the equation for n to know the budget:
60 = 1.2n
n = 60 / 1.2 = 50
Based on the above calculations, Jada's budget is 50$

So you have 21 people that you want to have meet in groups of 3. How many rounds of meeting would it take to have them all meet?
Answer:
1330 rounds of meetings
Step-by-step explanation:
You have a total of 21 people, and they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does not matter.
Formula for combination:
ₙCᵣ = [tex]\frac{n!}{r!(n-r)!}[/tex]
where n is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).
We plug in and get:
-> [tex]\frac{21!}{3!(21-3)!}[/tex]
-> 1330 different meetings for everyone to meet with each other in groups of 3.

A vector has a horizontal component of 14 and a vertical component of 36. Find the direction angle and the magnitude. Direction angle?
Answer:
The direction angle is 68.73 degrees and its magnitude is 38.62.
Step-by-step explanation:
Given that,
The horizontal component of a vector = 14
The vertical component of a vector = 36
Let the magnitude of a vector is v. So,
[tex]v=\sqrt{14^2+36^2} \\\\=38.62[/tex]
For direction,
[tex]\tena\theta=\dfrac{y}{x}\\\\=\dfrac{36}{14}\\\\\theta=\tan^{-1}(2.57)\\\\=68.73^{\circ}[/tex]
So, the direction angle is 68.73 degrees and its magnitude is 38.62.

Answer:
y = -5/2x + 7
Step-by-step explanation:
The line is perpendicular, so mx is the reciprocal of 2/5 which would be -5/2. Then you plug that and (4, -3) into the equation y = mx + b, which will come out as -3 = (-5/2)(4) + b. Multiply mx to get -3 = -10 + b. Add 10 to both sides to get 7 = b. Plug in mx and b into the equation and you have your answer.

3 + 2x = -6x + 4
what’s x
100 points
Answer:
x = 1/8
Step-by-step explanation:
Add 6x to both sides:
3 + 2x = -6x + 4
3 + 8x = 4
Subtract 3 from both sides:
8x = 1
Divide each side by 8:
x = 1/8
So, x = 1/8
