If O is an angle in standard position and its terminal side passes through the point
(8,5), find the exact value of cot 0 in simplest radical form.
Answer:
8/5
Step-by-step explanation:
Since the angle passes through 8,5. The horizontal side length is 8. The vertical length is 5 so now we must find the hypotenuse or radius side. Using the pythagorean theorem, that can be accomplished.
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
[tex] {8}^{2} + {5}^{2} = {r}^{2} [/tex]
[tex]64 + 25 = {r}^{2} [/tex]
[tex] \sqrt{89} [/tex]
So know me gonna to find our trig functions. Cot or cotangent is x/y so we plug that as x=8, y=5.
[tex] \frac{8}{5} [/tex]
so the answer. is 8/5

Answer:
C. -38
Step-by-step explanation:
We know that if the denominator is not given, then it is 1
So,
(-5/1) = (y-7/9)
Now, cross-multiply and set them equal
-45 = y - 7 Add both sides by 7
-38 = y

The product of two consecutive positive integers is 812. What is the value of the lesser integer? a. 7 b. 28 c. 58 d. 203
Answer:
The value of the lesser integer is [tex]28[/tex]
Step-by-step explanation:
Let two consecutive positive integers be [tex]x,x+1[/tex].
Product of two consecutive positive integers = [tex]x(x+1)=x^2+x[/tex]
Also, product of two consecutive positive integers is 812
So,
[tex]x^2+x=812\\x^2+x-812=0\\x^2+29x-28x-812=0\\x(x+29)-28(x+29)=0\\(x-28)(x+29)=0\\x=28,-29[/tex]
As [tex]x[/tex] is a positive integer,
[tex]x=-29[/tex] is rejected.
So,
[tex]x=28\\x+1=28+1=29[/tex]
Two positive integers are [tex]28,29[/tex]
The value of the lesser integer is [tex]28[/tex]

Answer:
x = 6
Step-by-step explanation:
Segment representing 2x - 1 is the mid segment of the given triangle.
Therefore, by mid segment theorem:
2(2x - 3) = 18
2x - 3 = 18/2
2x - 3 = 9
2x = 9 + 3
2x = 12
x = 12/2
x = 6
Answer:
x = 6
Step-by-step explanation:
D is the mid-point of AB (given)
E is the mid-point of AC (given)
Therefore, by mid-point theorem,
DE = 1/2 BC
=> 2x - 3 = 1/2 × 18
=> 2x - 3 = 9
=> 2x = 12
=> x = 6

(0,-9)after a rotation of 180 counterclockwise about the origin
The coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
The given coordinate is (0, -9).
Rotation rule:
Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise or counterclockwise direction, produces a point that has the coordinates (-x,-y).
Now, (0, -9) → (0, -(-9))
(0, -9) → (0, 9)
Therefore, the coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).

equivalent Find the number that makes the ratio equivalent to 1:7. 4:
Answer:
28
Step-by-step explanation:
Ratios are like fractions. Since you're finding an equivalent ratio, u can set them up like equivalent fractions and put an x where the missing number would go:
[tex]\frac{1}{7} = \frac{4}{x}[/tex]
You can either cross multiply and then solve for x, but it's easier to just think about it. The fractions are equivalent, right? So for them to be the same you'd have to do to the bottom what u do to the top.
To get from 1 to 4, you multiply by 4. By that logic, to get from 7 to x you'd have to multiply by 4 as well. Therefore x = 7x4, which is 28.
So x = 28
Write the equation of a line that passes through the point (0, 3) and (-4, 11). *
Answer:
[tex] \large \boxed{y = - 2x + 3}[/tex]
Step-by-step explanation:
Goal
Write the equation of a line with given coordinate pointsGiven
Coordinate points which are (0,3) and (-4,11).Step 1
Use the slope formula also known as rise over run to calculate the slope.[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
Substitute coordinate points in.
[tex]m = \frac{11 - 3}{ - 4 - 0} \\ m = \frac{8}{ - 4} \longrightarrow \frac{2}{ - 1} \\ m = - 2[/tex]
Step 2
Substitute the value of slope in the slope-intercept form.[tex] \large \boxed{y = mx + b}[/tex]
where m = slope and b = y-intercept.
[tex]y = - 2x + b[/tex]
Step 3
Substitute any given coordinate points in the new equation to find the value of b.Substitute both coordinate points still give the same solution.
Step 3.1 — (0,3)
[tex]y = - 2x + b \\ 3 = - 2(0) + b \\ 3 = 0 + b \\ 3 = b[/tex]
Step 3.2 — (-4,11)
[tex]y = - 2x + b \\ 11 = - 2( - 4) + b \\ 11 - 8 = b \\ 3 = b[/tex]
Therefore, the value of b is 3.
Step 4
Substitute the value of b in the equation.[tex]y = - 2x + b \\ y = - 2x + 3[/tex]
Hence, the equation of a line is y = -2x+3.

Partes de una potenciación:
La base es la cantidad que se multiplica por sí misma tantas veces como lo indique el exponente, en este caso la base es el número 6.
El exponente indica la cantidad de veces que la base se tiene que multiplicar por sí misma, en este ejemplo el exponente es el 3, el cual indica que el número 2 se tiene que multiplicar 3 veces por sí mismo, es decir 2 x 2 x 2. (Ojo: multiplicar 2 x 3 es un procedimiento equivocado en este caso de la potenciación).
La potencia es el 8; es el resultado de multiplicar 2 x 2 x 2

Every 10 min it goes down 10 degrees.
We need it to go down 205-180=25 degrees.

Answer:
Step-by-step explanation:
Noma cleans 12 pools in 8 hours
How many pools in how many minutes?
8 x 60= 480
He cleans 12 pools in 480 minutes
How many minutes does he take to clean a pool?
480/12 = 40
He cleans a pool in 40 minutes.
How much does he earn to clean a pool?
since he cleans 12 pools to earns $270
then 270/12 =22.5
Therefore, he charges $22.5 to clean a pool in 40 minutes.
Albert 9 pools in 7.5 hours
How many pools in how many minutes?
7.5 x 60= 450
He cleans 9 pools in 450 minutes
How many minutes does he take to clean a pool?
450/9 = 50
He cleans a pool in 50 minutes.
How much does he earn to clean a pool?
since he cleans 9 pools to earns $195.75
then 195.75/9 =21.75
Therefore, he charges $21.75 to clean a pool in 50 minutes.
