If sin theta= 4/5 and theta is in quadrant 2, the value of cot theta is . if necessary, use the slash mark ( / ) for a fraction bar.
Answers
a^2 + 4^2 = 5^2
a = 3
cos = -3/5
so tan would be -4/3
and then cot would be -3/4
i think that’s right ^
If sin θ= 4/5 and theta is in quadrant 2, the cot θ would be -3/4.
Which trigonometric functions are positive in which quadrant?
In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Given information; If sin θ= 4/5 and theta is in quadrant 2, we need to find the value of cot theta.
Since it’s in second quadrant, cos is going to be negative.
So, a^2 + 4^2 = 5^2
a^2 + 16 = 25
a^2 = 25 - 16 = 9
a = 3
therefore, we can conclude that cos θ = base / hypotenuse
cos θ =-3/5
Also, tan θ would be -4/3 and then cot θ would be -3/4.

Answers
Answer:
12(4) +6
48+6 = 54
y=54
Step-by-step explanation:
Step-by-step explanation:
Given function: y = 12x + 6
Input: x = -4
Replacing the value of x in function y,
y = 12 x (-4) + 6
y = -48 + 6
y = -42
If a cylinder with height 9 inches and radius 4 inches is filled with water, it can fill a certain pitcher. How many of these pitchers can a cylinder with the same height and a radius twice as large fill.
Answers
Answer:
We will need 4 pitchers to fill with water the new cylinder.
Step-by-step explanation:
The volume of the first cylinder is:
[tex]V_{1}=\pi r^{2}h[/tex] (1)
Where:
r is the radiush is the heightUsing the values of the problem we have:
[tex]V_{1}=\pi 4^{2}9[/tex]
[tex]V_{1}=452.4\: in^{3}[/tex]
We know that it can fill a certain pitcher, so the volume of the pitcher is 452.4 in³.
Let's find the new volume of the second cylinder to find how many of these pitchers can this cylinder.
We know that the cylinder has the same height and the radius is 2 times the older one.
[tex]V_{2}=\pi (2r)^{2}h[/tex]
[tex]V_{2}=\pi (2*4)^{2}9[/tex]
[tex]V_{2}=1809.6\: in^{3}[/tex]
Now, we just need to divide V(2) by V(1) to find the number of pitchers (np).
[tex]np=\frac{1809.6}{452.4}=4[/tex]
Therefore, we will need 4 pitchers to fill with water the new cylinder.
I hope it helps you!

21 x 21 = 441
Step-by-step explanation:
Whenever there is an exponent that is the many times you multiply the base by itself to.
Power is the result of multiplying two numbers together. The value of 21^2 is 441.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.
21^2
= 21²
= 21 × 21
= 441
Hence, the value of 21^2 is 441.

What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answers
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph

What is the equation of the line that passes through the points (0, 6) and (-3, 0) and is parallel to y = 2x + 5
Answers
answer:
y=2x+6
solution:
Alright, since the line is PARALLEL, the slope will remain the same. let call the # we will add to that b (like the 5 in y=2x+5).
so the formula will be y=2x+b
to find be, we will plug in one of the ordered pairs
6=2(0)+b
6=0+b
b=6
So, our equation is y=2x+6
to check:
(-3,0)
0=2(-3)+6
0=-6+6
0=0
Answer:
y = 2x + 6
Step-by-step explanation:
The equation for this is y=mx+b, m being for slope and b being the y-intercept.
The first and easiest way to figure out this first is by finding the slope. Now because you have the information that it needs to be parallel, it's very fast and simple. Parallel means that it has the same slope and the lines will never cross each other. So, since the slope for this is 2, the new line you will be making will also have a slope of 2.
EXTRA NOTE- if it were perpendicular, you'd want to do the opposite reciprocal. Instead of being 2, it'd be -1/2, but luckily we're just dealing with parallel.
Now we need to find what the y-intercept is. Since math basically has a formula for everything, you will be using y-y(1)= m(x-x(1)). Now that looks slightly confusing, but basically you will just plug your y value into the y(1) and x coordinate into x(1) to simplify into slope intercept form (don't forget your slope!). It's always easier to use positive numbers for this, so I'll be using the coordinates (0, 6) and plug it in.
REMEMBER- coordinates are (x, y). Don't get it mixed up!
1. Write out your equation: y - 6 = 2 ( x - 0 )
2. Distribute: y - 6 = 2x - 0
3. Add 6 to the other side to get into your slope intercept form: y = 2x + 6
And that's how you get your line. Hope this helped and made at least some sense. :)

Step-by-step explanation:
Based on the directions we know that both figures are similar, meaning there is a dilation factor changing the overall size of the figures. In order to find this dilation factor we can give it the value of x and multiply it to the various lengths of the smaller figure. Once this is done, we make these values equal to their the corresponding counterparts on the larger figure.
32x=40
x=5/4
Now that the dilation factor is found substitute its value for x
24(5/4)=30
