1) Find the missing side. Give your
answer in simplest radical form.
Answer:
x = 4
y = 4√3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = 8
Adjacent = y
Opposite = x
Recall: SOHCAHTOA
✔️To find x, apply SOH:
Sin 30 = Opp/Hyp
Sin 30 = x/8
x = 8 × sin 30
x = 8 × ½ (sin 30 = ½)
x = 4
✔️To find y, apply CAH:
cos 30 = Adj/Hyp
Cos 30 = y/8
y = 8 × Cos 30
y = 8 × √3/2 (cos 30 = √3/2)
y = 4 × √3
y = 4√3

analia wants to know which school has higher athletic achievement relative to the budget per student
Answer:
SAT average divided by budget per student
Graduation rate divided by budget per student
No. The definitions have opposite results.
Step-by-step explanation:
DID IT ON KHAN and
The key understanding here is that there isn't a single way to define "academic achievement." Graduation rate can be a good measure of that. Average SAT is also a good measure. The rate of students who are accepted into college can also be a good measure, but we are not given information about that.
Now let's go over the options and see which of them might be used to describe "academic achievements relative to the budget per student."
Hint #22 / 4
Definition Analysis Appropriate?
SAT average divided by budget per student "SAT average" is a measure of academic achievement. Dividing this by the budget per student gives us a good definition.

Hint #33 / 4
We are left with two definitions for academic achievements relative to the budget per student:
SAT average divided by budget per student

Circle A is located at (6, 5) and has a radius of 3 units. What is the equation of a line that is tangent to circle A from point C (9, 8)?
y = −x + 14
x = 9
y = x − 1
x = 4
Answer:
2nd
Step-by-step explanation:
The equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.
How to get straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
Given; Circle A is located at (6, 5) and has a radius of 3 units.
The slope;
m = (8- 5)/(9 -6) = 1
Substitute in the equation of line;
y = mx +c
8 = 1(9) + c
8 - 9 = c
c = -1
So, We get
y = x − 1
Hence the equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.

Is the coordinate pair (3, 3) a solution to the inequality y > 2x - 3?
Given:
The inequality is:
[tex]y>2x-3[/tex]
The point is (3,3).
To find:
Whether the coordinate pair (3, 3) is a solution to the given inequality or not.
Solution:
We have,
[tex]y>2x-3[/tex]
Check the inequality for the point (3,3). Substituting [tex]x=3,y=3[/tex], we get
[tex]3>2(3)-3[/tex]
[tex]3>6-3[/tex]
[tex]3>3[/tex]
This is a false statement because 3 is not greater than itself.
Since (3,3) does not satisfy the given inequality, therefore (3,3) is not a solution to the given inequality.
Now we can check the solution graphically. From the graph it is clear that the point (3,3) lies on the boundary line.
The boundary line is a dotted line, it means the point on the boundary line are not included in the solution set.
Therefore, (3,3) is not a solution to the given inequality.

Using the unit circle, the answer is C.
If you want a full in depth, answer:
The unit circle has a radius of 1.
3pi/4 is located in the 2nd quadrant.
That radian measures 135 degrees.
The 2nd quadrant start after 90 degrees.
To find the terminal angle, subtract 90 from 135.
Which gives you 45.
This means we are dealing with a 45-45-90 triangle.
Since our hypotenuse is 1, our y and x have to be
[tex] \frac{ \sqrt{2} }{2} [/tex]
Sin is positve in the 2nd quadrant so C is the answer.

Answer:
The team is measuring at 364 ft below the surface
Step-by-step explanation:
Here, we want to get the depth at which the pressure was measured at
to get this, we will have to use the equation that relates the pressure to the depth
From the question, we have this as;
P = 13 + 8/13(d)
From the question, P is 237
Substituting this into the equation, we have
237 = 13 + 8/13(d)
237-13 = 8/13(d)
224 = 8/13(d)
8d = 13 * 224
d = (13 * 224)/8
d = 364 ft

So, at this point, I don't even know what I'm doing, so I'm not going to guarantee that this is right, I'm sorry, but let's do some random math:
So we know that the length (the top and bottom) of the rectangle is 7 cm, we just have to figure out the width (the sides), and we're gonna do that by:
0.5 x 2 = 1
7 - 1 = 6
So now we just do the basic rectangle area calculation:
7 x 6 = 42
So, I hope that the area of the shaded area is 42cm²
