Answer:
[tex] \frac { 5\sqrt{21} }{ - 7} [/tex]
Step-by-step explanation:
Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r
[tex] {7}^{2} + {24}^{2} = {r}^{2} [/tex]
49+576=
[tex] {c}^{2} [/tex]
525=c^2
[tex] \sqrt{525} = 5 \sqrt{21} [/tex]
So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals
[tex] \frac{x}{r} [/tex]
cos=
[tex] \frac{ - 7}{5 \sqrt{21} } [/tex]
then we find secant which is the reciprocal of cos so we flip the numbers and that equals
[tex] \frac{5 \sqrt{21} }{ - 7} [/tex]

Your math teacher loves to collect markers and pencils. If she has 9 more markers than pencils and has a total of 41 writing utensils, how many pencils does your teacher have? please explain pleaseee
Answer:
16
Step-by-step explanation:
There is a total of 41 writing utensils, if you have 9 more pencils than markers you need to subtract 9 from 41. Then half that number so you will get the total amount of pencils.
41-9=32
32/2=16

Answer:
4x+2=22
4x=22-2
4x=20
x=20/4
x=5
Answer:
x = 5
Step-by-step explanation:
First step - subtract 2 from both sides:
4x + 2 - 2 = 22 - 2 which simplifies to 4x = 20
Second step - divide both sides by 4:
4x ÷ 4 = 20 ÷ 4 which simplifies to x = 5

The traffic lights at three different road crossings change after every 48 seconds, 72
seconds and 108 seconds respectively. If they change simultaneously at
7 a.m., at what time will they change simultaneously again?
please tell step by step
Answer:
7 : 7 : 12 am
Step-by-step explanation:
This question pretty much requires us to obtain the lowest number that is common to all three times. The qay to obtain this is by finding the LCM of all three numbers.
This is given as;
48 = 2 × 2 × 2 × 2 × 3
72 = 2 × 2 × 2 × 3 × 3
108 = 2 × 2 × 3 × 3 × 3
The LCM is = 2 × 2 × 2 × 2 × 3 × 3 × 3 = 432 seconds.
Converting to minutes by dividing by 60, the time is = 432 ÷ 60 min = 7 min 12 sec
The next time they would change simultaneously is; 7am + 7 min 12 sec = 7 : 7 : 12 am

Store A cost $6 for 3 boxes. Store B costs $5 for 2 boxes. Which store has the better deal? How do you know? please hurry
Hi there! Your answer to the problem would be Store A..
Step By Step Explainaction:
So we know that store A’s boxes cost $6 for each 3 boxes, and store be cost 5$ for 2 boxes.
Divide 6 with 3 since you want to know how much one would cost. 6 divide 3=6. Let check again by doing multiplication. 3x2 is also 6. This means that the cost for each box for Store A would be 2$.
Store B is the same but dividing 5$ with 2. 2x2=4 but we need to know 5. But 1 is actually .5 or 50% of 2. So it would be 2.5 or 2 and a remainder of 1. Same things...
So it would be Store A that gives cheaper cost. $2>$2.5
Given:
Store A costs $6 for 3 boxes. Store B costs $5 for 2 boxes.To find: Which store has the better deal.
Answer:
In order to do so, we'll need to divide the cost by the number of boxes to retrieve the cost of 1 box. The store with the lowest price for 1 box will have the better deal.
Let's first see what a box costs in Store A.
[tex]\sf \dfrac{Cost}{Number\ of\ boxes}\ =\ Cost\ of\ one\ box\\\\\\\dfrac{6}{3}\ =\ 2[/tex]
At Store A, the cost of a box is $2.
Now let's see what a box costs in Store B.
[tex]\sf \dfrac{Cost}{Number\ of\ boxes}\ =\ Cost\ of\ one\ box\\\\\\\dfrac{5}{2}\ =\ 2.5[/tex]
At Store B, the cost of a box is $2.5.
Since the cost at Store B seems to be a slightly higher price, Store A has the better deal.
Hope it helps. :)

Domain is the set of x-values that can be inputted into function f(x) Range is the set of y-values that are outputted by function f(x) Vertical Line Test - no function can have the same x-value for different y-coordinatesStep-by-step explanation:
According to the graph, our x-values span from 0 to 4. Since both are closed dot, they are inclusive in the domain:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
According to the graph, our y-values span from 0 to 4. Since both are closed dot, they are inclusive in the range:
Interval Notation - [0, 4]
Inequality Notation - 0 ≤ x ≤ 4
Since we see that each x-value has a unique y-value and passes the vertical line test.
∴ the relation is a function.
find the glide reflection image of the image of the black triangle for the composition
(R x-1 °T <0,-7>)
Answer
-17
Step-by-step explanation:
i used a calculator
The glide reflection of the figure is given below. Therefore, option D is the correct answer.
What is a glide reflection?Glide Reflection is a composition of transformations. In glide reflection, a translation is first performed on the figure then it is reflected over a line.
From the given figure, labelled the black triangle as A, B and C.
The coordinates of triangle ABC are; A= (2,8) , B= (2,5) and C=(6,5)
To find the glide reflection image of the triangle ABC.
Given: The rule of translation is: (x, y)→(x, y-7) and the line of reflection is x= 1.
Now, apply the rule of translation to the black triangle, and we get;
A(2, 8)→(2, 8-7)=A'(2, 1)
B(2, 5)→(2, 5-7)=B'(2, -2)
C(6, 5)→(6, 5-7)=C'(6, -2)
Now, apply the rule of reflection over the line x =1.
That is, (x, y)→(-x+2, y)
A'(2, 1)→(-2+2, 1)=A''(0, 1)
B'(2, -2)→(-2+2, -2)=B''(0, -2)
C'(6, -2)→(-6+2, -2)=C''(-4, -2)
You can see the graph of the Glide reflection as shown below.
Therefore, option D is the correct answer.
