What is Trigonometry?Trigonometry is a discipline of mathematics that studies the relationship between the sides of a triangle (right triangle) and their angles. There are six trigonometric functions that define the relationship between sides and angles.
1. Using Trigonometry
sin 60 = P/H
√3/2 = x/ 12
x = 12√3 / 2
x= 6√3
2. Using Trigonometry
sin 60 = P/H
1/√2 = 7√2 / x
x/√2 = 7√2
x = 14 unit
3. Using sine law
sin 75 /11 = sin 54 / x
0.965 / 11 = 0.809 / x
0.0877 = 0.809 / x
x = 9.224 miles

Give an example of a linear equation perpendicular to y=5
Final answer:
A linear equation perpendicular to y=5 is a vertical line, expressed as x=c, where c is any real number. For instance, x=2 is perpendicular to y=5.
Explanation:
A linear equation perpendicular to y=5 would need to have an undefined slope, meaning it's a vertical line. Since y=5 is a horizontal line, a perpendicular line will have no slope value that we can put in terms of y=mx+b, where m represents the slope and b represents the y-intercept. Thus, the equation will be of the form x=c, where c is any real number. This represents a vertical line that crosses the x-axis at the point (c,0).
For example, the linear equation x=2 is perpendicular to y=5 and crosses the x-axis at the point (2,0).

please show me how to solve ... -12x - 17 = -89
which number is a solution of the inequality 12 < y(8-y)
The solution to the inequality 12 < y(8 - y) is y such that 2 < y < 6.
The solution of the inequality 12 < y(8 - y), you can start by simplifying the expression on the right side: y(8 - y)
Distribute the y on the right side: 8y - [tex]y^2[/tex]
Now, substitute this expression back into the original inequality: [tex]12 < 8y - y^2[/tex]
Rearrange the terms to form a quadratic inequality: [tex]y^2 - 8y + 12 > 0[/tex]
Now, factor the quadratic expression: (y - 2)(y - 6) > 0
To solve for y, set each factor equal to zero and find the critical points: y - 2 = 0 or y - 6 = 0
Solving these equations gives y = 2 and y = 6.
Now, create intervals using these critical points and test a value in each interval:
1. Test y = 1: (1 - 2)(1 - 6) = (-1)(-5) = 5 > 0
2. Test y = 3: (3 - 2)(3 - 6) = (1)(-3) = -3 < 0
3. Test y = 7: (7 - 2)(7 - 6) = (5)(1) = 5 > 0
The solution is y such that 2 < y < 6
ab is tangent to the circle ad=4 and bc=3 solve for x
Answer:
Step-by-step explanation:
alright, lets get started.
bc and cd will be same as both are radius of the circle.
[tex]bc=cd=3[/tex]
[tex]ac=ad+cd[/tex]
[tex]ac=4+3[/tex]
[tex]ac=7[/tex]
as we know ab is tangent to the circle so, triangle abc will be a right triangle.
Using Pythagorean theorem
[tex]a^2+b^2=c^2[/tex]
[tex]3^2+x^2=7^2[/tex]
[tex]9+x^2=49[/tex]
Subtracting 9 from both sides
[tex]x^2=49-9=40[/tex]
[tex]x=\sqrt{40} =2\sqrt{10}[/tex]
So, the answer is [tex]2\sqrt{10}[/tex] : answer

Chad owns twice as many cds as carlin owns. if you add 6 to the number of cds chad owns and then divide by 7, you get the number of cds bryce owns. bryce owns 30 cds. how many cds does carlin own?
An equation is formed of two equal expressions. The number of CDs owned by Carlin is 102.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the following points:
Chad owns twice as many CDs as Carlin owns. if you add 6 to the number of CDs chad owns and then divide by 7, you get the number of CDs Bryce owns. Bryce owns 30 CDs.Let the variables represent the following numbers as shown,
CDs owned by Chad = M.Cds owned by Carlin = NCDs owned by Bryce = OThe number of CDs owned by Chad.
M = 2N ______(1)
The number of CDs owned by Carlin.
= N ________(2)
The number of CDs owned by Bryce.
O = (6+2N) / 7
And O = 30
30 = (6 + 2N) / 7 ________(3)
From (3), the value of N can be written as,
30 = (6 + 2N) / 7
Multiply both sides by 7
30 x 7 = 6 + 2N
210 = 6 + 2N
Subtract 6 on both sides.
210 - 6 = 6 + 2N - 6
204 = 2N
Divide both sides by 2.
102 = N
N = 102
Thus, the number of CDs owned by Carlin is 102.

I have a math question
For
the first question; we have a problem dealing with translations.
Our goal is to translate
the word problem into an algebraic one. So our numbers are
60, 2, and 5. Our variable, or the letter holding the unknown
number's place
value, is
N.
The
problem states that 60 is MORE THAN the PRODUCT of 5 and N. Focus
on the words I bolded and capitalized. These are your key words that
tells you what operations
you need to use. Note that 'product' signals the operation of
multiplication (Since the answer you get from multiplying numbers is
called the 'product'.) and
'more than' signals the operation of addition (Because you are left
off with more than you originally had before adding).
Now
that we know that our algebraic expression contains multiplication,
addition, letter N and the numbers 2 and 5; we can start plugging the
numbers in.
60
= 2 (more than) + (product of) 5N. The answer for the first
attachment is
B.
_____________________________________________________________
All
we need to do for the AB problem (Question 25 on your material) is
solve AB.
Note
1: When a problem has no operation separating two letters or numbers,
this means multiplication.
Note
2: A and B are variables. Variables are letters that stand for and
hold the place of our unknown quantities. However, the values are not
unknown anymore given the fact that the question tells us that A= 42
and B = 2. Thus we substitute A with 42 and B with 2, then work from
there. 42 * 2 =84. Answer = A.
____________________________________________________________________
And
finally, for question 26, we use PEMDAS. P = parenthesis (), E =
exponent x^2, M/D = x or /, A/S means + or subtraction.
According to PEMDAS, we first solve what's parenthesis, which is 77 – 32. Using mental math, 77 – 32 = 45. ( 7 – 3 = 4 and 7 – 2 = 5.). 5/9 * 45 is what we have left. 5 divided by 9 =0.5555555555555556. 0.5555555555555556 * 45 = 25. Answer is D.

(750/512)^1/3
what is equivilant to this??
Answer:
[tex]\frac{5\sqrt[3]{6}}{8}[/tex]
Step-by-step explanation:
We have been given an exponential number. We are supposed to simplify our given number.
[tex](\frac{750}{512})^{\frac{1}{3}[/tex]
Using fractional exponent rule [tex]x^\frac{m}{n}=\sqrt[n]{x^m}[/tex], w ecan write our given number as:
[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{(\frac{750}{512})^1}[/tex]
[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{750}{512}}[/tex]
We can rewrite 512 as [tex]8^3[/tex] and 750 as 125*6.
[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{125*6}{8^3}}[/tex]
We can rewrite 125 as [tex]5^3[/tex]
[tex](\frac{750}{512})^{\frac{1}{3}}=\sqrt[3]{\frac{5^3*6}{8^3}}[/tex]
Using radical rule [tex]\sqrt[n]{a^n}=a[/tex], we will get:
[tex](\frac{750}{512})^{\frac{1}{3}}=\frac{5\sqrt[3]{6}}{8}[/tex]
Therefore, [tex]\frac{5\sqrt[3]{6}}{8}[/tex] is equivalent to our given number.

the volume of the sphere is increased by 72.8%. what is the percentage increase in the radius?
Final answer:
The volume of a sphere increases by 72.8%, which after calculations, results in a 20% increase in the radius of the sphere.
Explanation:
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. An increase in volume by 72.8% implies that the new volume V' is equal to 1.728 times the original volume V. To find the percentage increase in the radius, we use the relationship between volume and radius:
V' = (4/3)πr'^3, where r' is the new radius after increase. Since V' = 1.728V, we have:
1.728 (4/3)πr³ = (4/3)π[tex]r'^3[/tex]Therefore, [tex]r'^3[/tex] = 1.728r³.After taking the cube root of both sides, we obtain:
r' = ∛1.728 * r ≈ 1.200 * rThus, the new radius is approximately 120% of the original radius, which means there is a 20% increase in the radius.
Final answer:
To calculate the percentage increase in the radius of the sphere when the volume is increased by 72.8%, we can use the formula for volume and solve for the new radius in terms of the original radius. The percentage increase in radius is then calculated by comparing the new and original radius.
Explanation:
The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius of the sphere. If the volume of the sphere is increased by 72.8%, we can calculate the new volume by multiplying the original volume by 1 + 0.728. Let's denote the original radius as r1 and the new radius as r2.
The formula for volume can be written as V = (4/3)πr³. Substituting r1 and r2 into the formula, we get:
Original volume: V1 = (4/3)πr1³New volume: V2 = (4/3)πr2³Since the two volumes are related by the percentage increase (1 + 0.728), we can write the equation:
(1 + 0.728)V1 = V2
Now, let's solve for r2 in terms of r1:
(1 + 0.728)V1 = (4/3)πr2³
r2 = ([(1 + 0.728)V1] * (3/4π))^(1/3)
Finally, we can calculate the percentage increase in the radius by comparing r2 to r1:
Percentage increase in radius = (r2 - r1) / r1 × 100%
