The rectangular coordinates form of r = 12 sinθ is x² + y² - 12y = 0

Given r = 12 sinθ and we are asked to convert this equation into rectangular coordinates.

The relation between polar coordinates (r,θ) and rectangular coordinates (x, y) is given by

                          x = r cosθ and y = r sinθ

Also, r² = (x² + y²)

r = 12 sinθ

Multiplying r both sides

r x r = 12 sinθ x r

   r² = 12r sinθ

We know r sinθ = y and r² = (x² + y²)

So, x² + y² = 12y

x² + y² - 12y = 0

Hence, the rectangular coordinates form is x² + y² - 12y = 0

A rashguard costs $25 at full price, which is calculated as 3x - 15 = 60.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given Blue Tide Swim Shop is having its annual summer sale,

rashguards sell for $5 less than the full price,

let the actual price of rashguards be x

price to be payed = x - 5

Miguel purchases 3 rashguards,

at cost  = $60

cost of 3 rashguards is 3(x - 5) = 3x - 15

3x - 15 = $60

3x = 60 + 15

3x = 75

x = 75/3

x = 25

cost of rashguards is $25.

Hence the actual cost is $25, and the equation is 3x - 15 = 60.

129 students had a private scholarship.

Out of the 843 students,

To calculate the total number of students with a private scholarship, we need to add the number of students who had a private scholarship (112) and the number of students who had both scholarships (17). This gives us a total of 129 students with a private scholarship. The rest of the students, who had either a government scholarship (80) or no scholarship (651), do not have a private scholarship.

209 students had only one of the two scholarships, so 209 - 129 = 80 students had a government scholarship.

So in total, 112 + 80 = 192 students had either a private or a government scholarship.

Therefore, 843 - 192 = 651 students did not have either a private or a government scholarship.

Using the definition of big o notation, t(n) = 32 * 4^n is O(f(n)) = 5^n with c = 26 and n0 = 1.

The definition of Big O notation states that a function t(n) is said to be O(f(n)) if there exist positive constants c and n0 such that |t(n)| <= c * |f(n)| for all n >= n0. In other words, t(n) grows no faster than f(n) as n becomes large.

To find the constants c and n0 that show that t(n) = 32 * 4^n is O(f(n)) = 5^n, we need to find a value of c and an n0 such that:

|32 * 4^n| <= c * |5^n|

for all n >= n0.

Let's start by finding a value for c that works for n = 1. We have:

|32 * 4^1| = 128 <= c * |5^1| = 5c

So, c >= 128 / 5 = 25.6.

Now let's try c = 26. We have:

|32 * 4^n| <= 26 * |5^n|

for all n >= 1.

Since 26 * |5^n| is an increasing function as n increases, we can conclude that:

t(n) = 32 * 4^n is O(f(n)) = 5^n

with c = 26 and n0 = 1.

The critical values for a two-sample z-test with a level of significance of 0.10 are -1.28 and 1.28.

This test is used to compare the proportions of two groups (males and females) who answered "yes" to the question "do you enjoy shopping for clothing?" The null hypothesis is that the proportion of males who enjoy shopping for clothing is equal to the proportion of females who enjoy shopping for clothing. The alternative hypothesis is that they are not equal.

To find the critical values, we use a standard normal table and find the z-scores that correspond to a cumulative probability of 0.05 (0.10/2) in both tails of the distribution. These values are -1.28 and 1.28.

In other words, if the calculated z-statistic is less than -1.28 or greater than 1.28, we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that the proportions of males and females who enjoy shopping for clothing are not equal.

You were on the right track, I totally understand why you'd get stuck where you are currently in the process. To start with, you technically found the wrong ratio between the two triangles. Your ratio is just 2x, while it should be 2x/5.

To start, let's find the ratio between triangle FEG and ABC by dividing angle F by and A:

[tex]R=\frac{2x}{5}[/tex]

Now, multiply angle B by this ratio:

[tex](x+4)(\frac{2x}{5} )=\frac{2x^2}{5}+\frac{8x}{5}=\frac{2x^2+8x}{5}[/tex]

We can now set this expression equal to angle E, as we have multiplied by the common ratio:

[tex]\frac{2x^2+8x}{5} =18[/tex]

This looks rather daunting, but let's keep calm... you can do this!!

Start by subtracting 18 from both sides:

[tex]\frac{2x^2+8x}{5}-18=0[/tex]

Now, let's get the whole expression under the denominator 5:

[tex]\frac{2x^2+8x-90}{5}=0[/tex]

Notice that the denominator can now be removed:

[tex]2x^2+8x-90=0[/tex]

Now, factor the equation (you could also use the quadratic eq if you want)

[tex]2(x-5)(x+9)=0[/tex]

Notice that we have two potential values for x (5 and -9).

Think about this logically... If we use -9 and plug it in for x, we will end up with values of -5 degrees for an angle, which is impossible! Therefore 5 is the only valid answer!

I encourage you to also approach the problem from a different angle and use the common factor (5/2x) and multiply it by 18 :)

Step-by-step explanation: A square root function has a range of y greater-than-or-equal-to 0.

For example, the function f(x) = √x has a domain of x greater-than-or-equal-to 0 and a range of y greater-than-or-equal-to 0. This is because the square root of a positive number is always positive, and the square root of 0 is equal to 0. So, for any value of x greater-than-or-equal-to 0, the corresponding value of y will always be greater-than-or-equal-to 0.

Other functions that have a range of y greater-than-or-equal-to 0 include:

the absolute value function: f(x) = |x|

exponential functions with positive bases: f(x) = e^x, f(x) = 2^x, etc.

This dilemma arises because oscillation requires two degrees of freedom while a equation one-dimensional system can never have more than one. An example of a constrained system is a basic harmonic oscillator.

This paradox results from the fact that oscillation needs two degrees of freedom whereas a one-dimensional system only has one. Position is the only variable in a one-dimensional system, hence oscillation is not feasible. But one example of a restricted system, where a constraint provides an additional degree of freedom, is a straightforward harmonic oscillator. The constraint in this scenario is a spring's force, which acts as a restoring force whenever the system deviates from its equilibrium state. The system can oscillate and move back and forth along the x-axis thanks to this restoring force. Thus, although having only one degree of freedom, the basic harmonic oscillator is an example of a one-dimensional system that can oscillate.
