Answer:
A
Step-by-step explanation:
We are given:
[tex]\displaystyle \cos(\theta)=-\frac{12}{13},\,\theta\in\text{QIII}[/tex]
Since cosine is the ratio of the adjacent side over the hypotenuse, this means that the opposite side is (we can ignore negatives for now):
[tex]o=\sqrt{13^2-12^2}=\sqrt{25}=5[/tex]
So, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.
And since θ is in QIII, sine/cosecant is negative, cosine/secant is negative, and tangent/cotangent is positive.
Cosecant is given by the hypotenuse over the opposite side. Thus:
[tex]\displaystyle \csc(\theta)=\frac{13}{5}[/tex]
Since θ is in QIII, cosecant must be negative:
[tex]\displaystyle \csc(\theta)=-\frac{13}{5}[/tex]
Our answer is A.

⚠︎ 65 IS YOUR ANSWER!Step-by-step explanation:
180-50 = 130
130 / 2= 65
Answer:
x=65
Step-by-step explanation:
you can set up a equation
50 + x+x =180 = 50 + 2x =180
then minus the 50
2x= 130 and the divide by 2
x=65
Determine if \sqrt{3}
3
is rational or irrational and give a reason for your answer.
Answer:
Irrational
Step-by-step explanation:
The square root of 3 is not a perfect square, therefore it is irrational. Another way you could see if it is rational is if it can be put in a fraction, if it can't, then it is irrational.

Answer:
[tex]7xy^{2} \sqrt[3]{2xy}[/tex]
Step-by-step explanation:
[tex]\sqrt[3]{686x^{4} y^{7}}[/tex]
[tex]686 = 343 * 2[/tex]
[tex]x^{4} = x^{3} * x[/tex]
[tex]y^{7} = y^{3} * y^{3} * y[/tex]
[tex]\sqrt[3]{343} =7[/tex]
[tex]\sqrt[3]{x^{3}} = x[/tex]
[tex]\sqrt[3]{y^{3}* y^{3}}[/tex] = [tex]y^{2}[/tex]
so you're left with 2, x, and y inside the cube root, and 7, x, and y^2 outside
[tex]7xy^{2} \sqrt[3]{2xy}[/tex]
| 2. On rectangle ABCD below, if A is located at
(3, 4) and B is located at (7,6), is the slope
of BC ?
necal ve
rec
Answer:
-2
Step-by-step explanation:
Given that:
A = (3, 4) ; B = (7, 6)
In triangle ABCD, AB and BC are Perpendicular lines :
Slope AB = Rise / Run = (y2 - y1) / (x2 - x1)
y2 = 6 ; y1 = 4 ; x2 = 7 ; x1 = 3
Slope AB = (6 - 4) / (7 - 3) = 2 / 4 = 1 / 2
To obtain the slope of BC:
RECALL:
product of the slope of 2 Perpendicular lines = - 1
Slope AB * Slope BC = - 1
1 / 2 * slope BC = - 1
Slope BC = - 1 ÷ 1/2
Slope BC = - 1 * 2/1
Slope BC = - 2
HENCE, slope of BC = - 2

Step-by-step explanation:
Rewrite the rational function g(x) =x-9/x in the form g(x) = c+ r/x, where c and r are constants.
Answer:
g(x) = 1 - 9/xStep-by-step explanation:
Given the rational function g(x) =(x-9)/x, we are to express in the form g(x) = c+ r/x, where c and r are constants.
g(x) = (x-9)/x
Expressing as partial fraction since they have the same denominator
g(x) = x/x - 9/x
Since x/x = 1, hence;
g(x) = 1 - 9/x
Comparing with g(x) = c+ r/x, c= 1 and r = -9
Hence the equivalent expression is g(x) = 1 - 9/x

Define the variables for the situation. Then enter an equation.
Jana's age plus 8 equals her sister's age.
j = Jana's age B
s = sister's age e
Enter an equation:

Answer:
Definitions of the variables in the situation:
J = Jana's age
S = Sister's age
The Equation:
J + 8 = S
Step-by-step explanation:
Explanation:
In the equation we will use the variable J for Jana and S for Janna's sister. Since we know Jana's age plus 8 equals her sister's age, the equation will be J + 8 = S

Marcos buys 20 folders and 10 binders for a total of $100. Alicia buys 10 folders and 20 binders for $110. What is the price of each folder and each binder?
Answer:
folder is $3 binder is $4
Step-by-step explanation:
Let folder be x and binders be y
Marcos
20x+10y= 100----------1
Alicia
10x+20y= 110-------------2
solve 1 and 2
20x+10y= 100 X 1
10x+20y= 110 X 2
20x+10y= 100
-20x+40y= 220
-30y= -120
y= 120/30
y= 4
put y= 4 in 1
20x+10y= 100
20x+10(4)= 100
20x+40=100
20x=100-40
20x=60
x= 60/20
x=3
Company A charges $125 annual fee plus $5 per hour car share fee.
Company B charges $80 plus $10 per hour. What is the minimum number of
hours that a car share needs to be used per year to make company A a better
deal?
Answer:
Greater than 9 hours.
Step-by-step explanation:
Company A annual fees = $125
Company A share fee = $5 per hour
Let number of hour be x, then
Company A total fee = $125 + 5x
Similarly, Company B annual fees = $80
Company B share fee = $10 per hour
Let number of hour be x, then
Company B total fee = $80 + 10x
If company A is a better deal, then
125 + 5x < 80 + 10x
= 125 - 80 < 10x - 5x
= 45 < 5x
= x > 45÷ 5
= x > 9
So, number of hours must be greater than 9 hours.

Answer:
y = 4.375x + 2.5
Step-by-step explanation:
The equation of the line is expressed as y = mx+c
m is the slope
c is the intercept
Using the coordinate points (0, 2.5), (4, 20)
Slope m = 20-2.5/4-0
m = 17.5/4
m = 4.375
Get the intercept
Substitute (0, 2.5) and m = 4.375 into y - mx+c
2.5 = 4.375(0) + c
2.5 = c
Get the equation required
y = 4.375x + 2.5
