Answer:
±1, ±2, ±7, ±14
Step-by-step explanation:
The rational root theorem tells you any rational roots will be of the form ...
±(divisor of the constant)/(divisor of the leading coefficient)
For this function, that means rational roots will be of the form ...
±(divisor of 14)

What is cos(338)? Solve by hand, no calculator.
Correct answer gets BRAINLIEST.
9514 1404 393
Answer:
0.927184
Step-by-step explanation:
Assuming you want cos(338°), it is equal to cos(22°). This value is an irrational root of a 26th-degree polynomial. (Neither the polynomial, nor the root are easy to find by hand.)
The values of trig functions for 30° and 45° are well-known, as are half-angle and angle sum/difference formulas. The nearest angle for which cosine is relatively easy to find is 22.5°. A 2nd-order Maclaurin series expansion of the cosine function about that angle gives the approximation ...
cos(x) ≈ cos(π/8)(1 -π²/128) +π/8·sin(π/8) +(π/8·cos(π/8) -sin(π/8))x -1/2·cos(π/8)x²
For your angle of 22°, the value of x needed in this expression is 11π/90. The values of cos(π/8) and sin(π/8) are the irrational numbers ...
cos(π/8) = √(2 +√2)/2 ≈ 0.92387953
sin(π/8) = √(2 -√2)/2 ≈ 0.38268343
If you use the approximation pi ≈ 355/113, both for the above formula and for the angle of interest, this reduces to the sum ...
cos(22°) ≈ 71√(2-√2)/16272 +132383951√(2+√2)/264777984
This would be tedious to calculate by hand, but is not impossible. The value this sum produces will be correct when rounded to 7 decimal digits.

Before calculators, trig function values were found in published tables. These days, tables are available on-line. Previously, they were published in books, usually along with information that helped with interpolation between table values, when necessary. The attachment shows a portion of an online cosine table suitable for answering your question.

Before calculators, mathematicians spent lifetimes calculating accurate trig tables. For all but a very few angles, the cosine function of rational degree values will be an irrational number, as it is for cos(22°).
check all that apply. if csc0 =13/12 then:
a:tan0= 12/5
b:sec0= 12/13
c: sin0=12/13
d: cos0=12/13
Answer:
a:tan0= 12/5
c: sin0=12/13
Step-by-step explanation:
cosec t(heta) = 13/12
1/sin t = 13/12
sin t = 12/13
cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169
cos t = 5/13
tan t = sin t/ cos t = (12/13) / (5/13) = 12/5
sec t = 1 / cos t = 13/5
Answer: A ) and C ) are correct:
tan theta = 12/5 and sin theta = 12/13

Answer:
Solution: (3,5)
Step-by-step explanation:
y = x + 2 and
y = - x + 8
y = y
x + 2 = -x + 8
x + x = 8 - 2
2x = 6
x = 6/2
x = 3
Substitute x for 3 in one of the equations to find y.
y = 3 + 2
y = 5

Consider the following vectors.
u = i + 4 j − 2 k, v = 4 i − j, w = 6 i + 7 j − 4 k
Find the scalar triple product u · (v ⨯ w).
u · (v ⨯ w) =
Are the given vectors coplanar?
Yes, they are coplanar.
No, they are not coplanar.
Need Help? Read It
The scalar triple product is 0.
If v = 4i - j and w = 6i + 7j - 4k, then their cross product is
v × w = (4i - j) × (6i + 7j - 4k)
v × w = 24 (i × i) + 28 (i × j) - 16 (i × k) - 6 (j × i) - 7 (j × j) + 4 (j × k)
v × w = 28k - 16 (-j) - 6 (-k) + 4i
v × w = 4i + 16j + 34k
and
u • (v × w) = (i + 4j - 2k) • (4i + 16j + 34k)
u • (v × w) = 4 + 64 - 68
u • (v × w) = 0
Yes, they are coplanar.
The vectors v and w together span a plane. v × w is a vector that is perpendicular to this plane. Since the dot product of u with this vector is 0, this means u is perpendicular to v × w, which in turn means that u is in the same plane as v and w.

You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?
The total money you have is $40.14.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
There are 7 times as many nickels as pennies
Let there are n nickles and p pennies.
⇒ p = 7n
Now, there are 16 nickels and pennies altogether
⇒ p + n = 16
Put p = 7n we get,
⇒ 7n + n = 16
⇒ 8n = 16
⇒ n = 16/8
⇒ n = 2
Therefore, p = 7*2
⇒ p = 14
Thus there 14 pennies and 2 nickels.
Now, since 1 penny = 0.01 dollars
and 1 nickel = 20 dollars
⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar
and, 2 nickel = 2*20 dollars = 40 dollars
So, Total money = $40 + $0.14
⇒ Total money = $40.14
Thus, the total money you have is $40.14.

Answer:

Step-by-step explanation:
1. We can use the exterior angle theorem to find the value of y. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote sides. This means that (y - 25) + (y + 12) = y + 43
2. (Solving)
Step 1: Simplify both sides of the equation.
[tex]y + 43 = y - 25 + y + 12[/tex] [tex]y + 43 = (y+y)+(-25+12)[/tex] [tex]y + 43 = 2y -13[/tex]Step 2: Subtract 2y from both sides.
[tex]y + 43 - 2y = 2y - 13 - 2y[/tex] [tex]-y + 43 = 13[/tex]Step 3: Subtract 43 from both sides.
[tex]-y + 43 - 43 = 13 - 43[/tex] [tex]-y = -56[/tex]Step 4: Divide both sides by -1.
[tex]\frac{-y}{-1} = \frac{-56}{-1}[/tex] [tex]y = 56[/tex]Step 5: Check if solution is correct.
[tex](56) + 43 = (56) - 25 + (56) + 12[/tex] [tex]109 = 31 + 56 + 12[/tex] [tex]99 = 87 +12[/tex] [tex]99 = 99[/tex]Therefore, y = 56.

Suppose the value of x varies from x = a to x = b . There are at least two ways of thinking about what percent x changed by. We'll explore two of them here. For each of the following questions, write an expression in terms of a and b to answer the question. Method 1 b is how many times as large as a ? times as large Therefore, b is what percent of a ? % Hence, if x varies from x = a to x = b , x changes by what percent?
The change in the value of x, as a percentage, is given by:
[tex]\frac{b - a}{a} \times 100\%[/tex]
The percentage change is given by the change multiplied by 100% and divided by the initial value.
In this question, x varies from [tex]x = a[/tex] to [tex]x = b[/tex], which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:
[tex]\frac{b - a}{a} \times 100\%[/tex]
