What is the exact value of tan
(19pie/12)
Answer:
[tex]\displaystyle -\sqrt{3} - 2[/tex]
Explanation:
If you recall the unit circle [from the polar graph], you would have no trouble at all figuring this out, but sinse you have trouble, do not worry about it. So, here is what you should have realised:
[tex]\displaystyle \boxed{1\frac{1}{2}\pi} = \frac{18}{12}\pi[/tex]
If you did not notise, [tex]\displaystyle 1\frac{7}{12}\pi,[/tex]or [tex]\displaystyle \frac{19}{12}\pi,[/tex]is just [tex]\displaystyle \frac{\pi}{12}[/tex]more than [tex]\displaystyle 1\frac{1}{2}\pi,[/tex]which means the exact value will either be a radical, followed by an integer or just a radical. In this case, accourding to the unit circle, you will have a radical, followed by an integer, and that will be this:
[tex]\displaystyle \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi} = tan\:1\frac{7}{12}\pi \\ \\ \boxed{-\sqrt{3} - 2} = \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi}[/tex]
It is all about memorisation of the unit circle, which I know is difficult, but you will get used to it soon.
*Now, if you had to find [tex]\displaystyle cos\:\frac{7}{12}\pi,[/tex]then the exact value would be the OPPOCITE of the exact value of [tex]\displaystyle sin\:\frac{7}{12}\pi,[/tex]which is [tex]\displaystyle -\frac{\sqrt{2} + \sqrt{6}}{4},[/tex]because you would be crossing into the second quadrant where the x-coordinates are negative, accourding to both the cartesian and polar graphs. In addition, sinse you ALREADY have both values for sine and cosine [accourding to your PREVIOUS QUESTION ASKED], all you need to do is divide both values in the order given above to arrive at the exact value for [tex]\displaystyle tan\:1\frac{7}{12}\pi.[/tex]

gerad wrote down the sum of the swuares of two numbers as shown. Unfortunately sone of the digits cannkt be seen because they are covered in ink. What is the last digit of the first number? Please I really need this for a test.
The equation of the sum of any two squares x and y is x^2 + y^2 = (x + y)^2 - 2xy
How to determine the last digitThe question is incomplete, as there are no parameters to determine the last digit of the first number.
So, I will give a general explanation
The sum of squares of two numbers x and y is:
[tex]x^2 + y^2 = (x + y)^2 - 2xy[/tex]
Assume the numbers are 5 and 6, then the equation becomes
[tex]5^2 + 6^2 = (5 + 6)^2 - 2*5*6[/tex]
Evaluate
[tex]5^2 + 6^2 = 61[/tex]

Anja simplified the expression StartFraction 10 x Superscript negative 5 Baseline Over Negative 5 x Superscript 10 Baseline EndFraction to StartFraction 15 Over x Superscript 15 Baseline EndFraction. What mistake did Anja make? She divided the exponents instead of subtracting them. She divided the coefficients instead of subtracting them. She subtracted the coefficients instead of dividing them. She subtracted the exponents instead of dividing them.
The mistake that Anja made during the simplification of the considered expression is given by: Option C: She subtracted the coefficients instead of dividing them
What are coefficients?Constants who are in multiplication with variables are called coefficients of those variables.
For example, in [tex]10x^2[/tex] we have 10 as coefficient of [tex]x^2[/tex]
Those variables who have got no visible coefficient has 1 as their coefficient. Thus, [tex]x^2[/tex] has got its coefficient as 1. It is true since 1 multiplied with any number is that number itself.( [tex]x^2 = 1 \times x^2[/tex] )
What are some basic properties of exponentiation?If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c[/tex]
For the considered situation, the expression that Anja is simplifying is:
[tex]\dfrac{10x^{-5}}{-5x^{10}}[/tex]
Anja simplified it to [tex]\dfrac{15}{x^{15}}[/tex]
She performed operations with variable 'x' correctly since
[tex]\dfrac{x^{-5}}{x^{10}} = \dfrac{1}{x^5} \times \dfrac{1}{x^{10}} = \dfrac{1}{x^{15}}[/tex]
But coefficients will also get divided. Instead of dividing 10 by -5, she subtracted them (as 10 - (-5) = 10 + 5 = 15)
This was her mistake.
The correct simplification would be: [tex]\dfrac{10x^{-5}}{-5x^{10}} = \dfrac{10}{-5} \times \dfrac{x^{-5}}{x^{10}} = -2 \times \dfrac{1}{x^{15}} = \dfrac{-2}{x^{15}} = -2x^{-15}[/tex]
Thus, the mistake that Anja made during the simplification of the considered expression is given by: Option C: She subtracted the coefficients instead of dividing them

Together, teammates Pedro and Ricky got 2690 base hits last season. Pedro had 284 more hits than Ricky. How many hits did each player have?
Subtract the difference:
2690 - 284 = 2406
Divide by 2:
2406 / 2 = 1203
Ricky Had 1,203
Pedro had 1203 + 284 = 1,487

For which equation does the point (2, 6) represent a possible solution?
part one is -3 and 7
part two is -3
Answer:
Given equation:
[tex]\sqrt{30-2x} =x-3[/tex]
Square both sides:
[tex]\implies (\sqrt{30-2x})^2 =(x-3)^2[/tex]
[tex]\implies 30-2x =(x-3)^2[/tex]
Expand the right side:
[tex]\implies 30-2x =x^2-6x+9[/tex]
Add [tex]2x[/tex] to both sides:
[tex]\implies 30 =x^2-4x+9[/tex]
Subtract 30 from both sides:
[tex]\implies x^2-4x-21=0[/tex]
Factor:
[tex]\implies (x-7)(x+3)=0[/tex]
Therefore,
[tex]x-7=0 \implies x =7[/tex]
[tex]x+3=0 \implies x=-3[/tex]
Substitute both values of [tex]x[/tex] into the original equation to check:
[tex]x=7 :[/tex]
[tex]\implies\sqrt{30-2(7)} =7-3[/tex]
[tex]\implies 4=4[/tex]
correct!
[tex]x=-3[/tex]
[tex]\implies\sqrt{30-2(-3)} =-3-3[/tex]
[tex]\implies 6 \neq =-6[/tex]
incorrect!
Therefore, [tex]x=7[/tex] is the only correct solution, and [tex]x=-3[/tex] is the extraneous solution
**Extraneous solution: a root of a transformed equation that is not a root of the original equation**
A banner is hung for a party. The distance from a point on the bottom edge of the banner to the floor can be determined by using the function f(x) = 0.25 x2 − x + 9.5 , where x is the distance, in feet, of the point from the left end of the banner. How high above the floor is the lowest point on the bottom edge of the banner? Explain.
That's possible when function tends to zero
[tex]\\ \rm\hookrightarrow 0.25x^2-x+9.5=0[/tex]
[tex]\\ \rm\hookrightarrow 1/4x^2-x+19/2=0[/tex]
[tex]\\ \rm\hookrightarrow x^2-x+38=0[/tex]
[tex]\\ \rm\hookrightarrow x=\dfrac{1\pm\sqrt{1-152}}{2}[/tex]
[tex]\\ \rm\hookrightarrow x=\dfrac{1\pm\sqrt{151}i}{2}[/tex]
Answer:
8.5 ft
Step-by-step explanation:
[tex]f(x) = 0.25x^2 - x + 9.5[/tex]
To find the minimum point of the function, differentiate:
[tex]f'(x) = 0.5x - 1[/tex]
set to zero and solve for x:
[tex]f'(x) =0\\ \implies0.5x - 1=0\\\implies x=2[/tex]
Substitute found value of x into function to find y (height):
[tex]f(2) = 0.25(2)^2 - 2 + 9.5=8.5[/tex]
Therefore, the lowest point on the bottom edge of the banner is 8.5 ft above the floor.
