Hey guys please help? Trigonometry
So, the task is: find cos a, if:
1) sin a = (3√11)/10, a ∈ (0; π/2)
2) sin a = (3√11)/10, a ∈ (π/2; π)
Could someone please explain how to solve it? I can't figure out what difference a ∈ (0; π/2) and a ∈ (π/2; π) make in the way I have to solve it mmh... I'll pin my attempt to do the first one (failed for some reason)
Step-by-step explanation:
a ∈ (0; π/2) here means that our angle, a must lie between 0 and pi/2, exclusive.
So this mean our angle must be in between 0 and pi/2, but can not be neither 0 and pi/2.
Here we have
[tex] \sin( \alpha ) = \frac{3 \sqrt{11} }{10} [/tex]
We must find cos.
Using the Pythagorean theorem
[tex]( \sin( \alpha ) ) {}^{2} + ( \cos( \alpha ) ) {}^{2} = 1[/tex]
It is mostly notated as this,
[tex] \sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1[/tex]
But they mean the same thing, we know
[tex] \sin( \alpha ) = \frac{3 \sqrt{11} }{10} [/tex]
So we plug that in for sin a.
[tex]( \frac{3 \sqrt{11} }{10} ) {}^{2} + \cos {}^{2} ( \alpha ) = 1[/tex]
[tex] \frac{99}{100} + \cos {}^{2} ( \alpha ) = 1[/tex]
[tex] \cos {}^{2} ( \alpha ) = \frac{100}{100} - \frac{99}{100} [/tex]
[tex] \cos {}^{2} ( \alpha ) = \frac{1}{100} [/tex]
Since cos is Positve over the interval (0; π/2), we take the positive or principal square root.
[tex] \cos( \alpha ) = \frac{1}{10} [/tex]
2. We would get the same work for the second part, the only difference is that cosine is negative over the interval
(π/2, π)
So the answer for 2 is
[tex] \cos( \alpha ) = - \frac{1}{10} [/tex]
Disclaimer: Your work you did was correct, just remember for fractions like
[tex]1 - \frac{99}{100} [/tex]
Convert 1 into a fraction that has a denominator of 100.
[tex] \frac{100}{100} - \frac{99}{100} = \frac{1}{100} [/tex]
Brayden has 24 feet of fence available to build a rectangular fenced in area. If the width of the rectangle is xx feet, then the length would be \frac{1}{2}(24-2x). 2 1 (24−2x). A function to find the area, in square feet, of the fenced in rectangle with width xx is given by f(x)=\frac{1}{2}x(24-2x).f(x)= 2 1 x(24−2x). Find and interpret the given function values and determine an appropriate domain for the function.
The maximum area is achieved when the rectangle is a square of side 6 feet, with a domain, 0 < x < 12.
The perimeter available with Brayden is 24 feet.
The width of the rectangle is assumed to be x feet.
The length can be calculated using the formula:
2(length + width) = perimeter,
or, 2length + 2width = perimeter,
or, 2length = perimeter - 2width,
or, length = (1/2)(perimeter - 2 width).
Substituting the values, we get:
length = (1/2)(24 - 2x).
The area can be calculated using the formula:
Area = length*width.
Substituting the values, we get:
Area = (1/2)(24 - 2x)x = (1/2)x(24 - 2x).
Now, we need to maximize the area for the given perimeter.
For that, we differentiate the area function, with respect to its width x.
d(Area)/dx = (1/2)(24 - 2x) + (1/2)x(-2),
or, d(Area)/dx = 12 - x - x = 12 - 2x ... (i).
To check for the point of inflection, we equate this to zero, to get:
12 - 2x = 0,
or, 2x = 12,
or, x = 6.
To check whether this is maximum or minimum, we differentiate (i) with respect to x to get:
d²(Area)/dx² = -2 which is less than 0, implying area is maximum at x = 6.
Thus, the maximum area is achieved when the width is 6 feet.
Length = (1/2)(24 - 2x) = (1/2)(24 - 2*6) = (1/2)12 = 6.
Thus, the maximum area is achieved when the length is 6 feet.
The area function is, area = (1/2)x(24 - 2x).
We know that the area is always greater than 0, thus, we can show that:
(1/2)x(24-2x) > 0,
or, x(24 - 2x) > 0,
or, x(12 - x) > 0, which is true when 0 < x < 12.
Thus, the domain of the area function is 0 < x < 12.
Thus, the maximum area is achieved when the rectangle is a square of side 6 feet, with a domain, 0 < x < 12.

Which of these is a simplified form of the equation 7p 4 = − p 9 2p 3p? 13p = 13 3p = 5 7 = 4 11 = 15
Answer:
[tex]\boxed{\sf{3p=5}}[/tex]Step-by-step explanation:
To find:
The value of pGiven:
7p + 4 = −p + 9 + 2p + 3p[tex]\sf{7p+4=-p+9+2p+3p}[/tex]
Isolate the term of p, from one side of the equation.
Combine like terms.
[tex]\rightarrow \sf{7p+4=-p+2p+3p+9}[/tex]
Add the numbers from left to right.
-p+2p+3p=4p
7p+4=4p+9
Then, you subtract by 4 from both sides.
[tex]\sf{7p+4-4=4p+9-4}[/tex]
Solve.
7p=4p+5
Subtract by 4p from both sides.
7p-4p=4p+5-4p
Solve.
[tex]\boxed{\sf{3p=5}}[/tex]
Divide by 3 from both sides.
3p/3=5/3
Solve.
p=5/3
Divide is another option.
5/3=1.6666
So, the final answer is 3p=5.

Assume that adults have iq scores that are normally distributed with a mean of μ=100 and a standard deviation σ=15. find the probability that a randomly selected adult has an iq less than 130
The probability that a randomly selected adult has an IQ less than 130 is 0.9332
For given question,
We have been given adults IQ scores that are normally distributed with a mean of μ = 100 and a standard deviation σ = 15.
We need to find the probability that a randomly selected adult has an IQ less than 130
Sketch the curve.
The probability that X < 130 is equal to the area under the curve which is less than X = 130
Since μ = 100 and σ = 15 we have:
⇒ P ( X < 130 ) = P ( X- μ < 130 - 100 )
⇒ P ( X < 130 ) = P((X− μ)/ σ < 130 - 100/20 )
Since (X-μ)/σ = Z and (130 - 100)/20 = 1.5 we have:
P (X < 130) = P (Z < 1.5)
Now, we use the standard normal table to conclude that:
P (Z < 1.5) = 0.9332

Round the angle measure to the nearest whole degree. ( Picture is not drawn to scale )
Answer:
4 degrees ( to nearest degree).
Step-by-step explanation:

A company estimates that its cost and revenue can be modeled by the functions C)-0.75x+20,000
and R(x)-1.50x where x is the number of units produced. The company's profit, P, is modeled by
P(z) R(x)-C(z). Find the profit function P(x).
Let C(x) = -0.75x + 20,000 and R(x)= -1.50x then the profit function exists noted as P(x) = R(x) - C(x)
P(x) = -1.50x - (-0.75)x + 20,000
P(x) = -0.75x + 20000
Therefore, the profit function exists -0.75x + 20000.
How to find profit function?
The profit function can be estimated by subtracting the cost function from the revenue function. Let profit be expressed as P(x), the revenue as R(x), the cost as C(x), and x as the number of items traded. Then the profit function exists noted as P(x) = R(x) - C(x).
Given:
C(x) = -0.75x+20,000 and R(x)= -1.50x
P(x) = R(x) - C(x)
= -1.50x - (-0.75)x + 20,000
= -1.50x + 0.75x + 20,000
Apply rule -(-a) = a
= -1.5x + 0.75x + 20000
Add similar elements:
-1.5 x + 0.75x = -0.75x
P(x) = -0.75x + 20000

38% of e
is 190.
Equation:
e=
Answer:
Step-by-step explanation:
400*60% can be rewriten as 400×0.6 which is 240, so a is false.
the same steps can be repeated for b and c
b) 200*0.6=120, therefore is false
c) 120*0.6=72, therefore is false
2)
[tex]60 percent * x=87\\0.6x=87\\x=\frac{87}{0.6} \\\\x=145[/tex]
Now we check the answer by using the same steps in problems a,b,c
[tex]145*0.6=87\\87=87[/tex]
3)
[tex]0.6c=43.2\\c=\frac{43.2}{0.6} \\c=72[/tex]
and finally
[tex]0.38e=190\\e=\frac{190}{0.38} \\e=500[/tex]

use substitution to solve the system 3x+8y = -56 2x-y = 7
Answer: x = 0 ; y = -7
Step-by-step explanation:
Given equation:
1) 3x + 8y = -56
2) 2x - y = 7
Subtract 2x on both sides of 2) equation to isolate y-value
2x - y - 2x = 7 -2x
-y = 7 - 2x
Divide -1 on both sides of 2) equation
-y / -1 = (7 - 2x) / -1
y = 2x - 7
Current system
1) 3x + 8y = -56
2) y = 2x - 7
Substitute 2) equation into the y-value of 1) equation
3x + 8 (2x - 7) = -56
Simplify by distributive property
3x + 8 × 2x - 8 × 7 = -56
3x + 16x - 56 = -56
Combine like terms
19x - 56 = -56
Add 56 on both sides
19x - 56 + 56 = -56 + 56
19x = 0
Divide 19 on both sides
19x / 19 = 0 / 19

Substitute the x-value into one of the equations to find the y-value
2x - y = 7
2 (0) - y = 7
0 - y = 7
-y = 7
[tex]\Large\boxed{y=-7}[/tex]
Hope this helps!! :)
