A Ferris wheel has a diameter of 100 feet. The highest point of the wheel is 125 feet. The y-axis represents the center of the w

Free_Kalibri [48]

Answer: $x^2+(y-125)^2=2500$

Step-by-step explanation:

Given: The diameter of the Ferris wheel= 100 feet

therefore, the radius of the Ferris wheel= 50 feet

Also, the highest point of the wheel is 125 feet.

Since , y axis represents the center of the wheel.

The center of the wheel= (0,125)

The equation of circle with center (h,k) and radius 'r' is given by :

$(x-h)^2+(y-k)^2=r^2$

Thus, the equation of the circle with center (0,125) and radius=50 is given by :-

$(x-0)^2+(y-125)^2=(50)^2\\\Rightarrow\ x^2+(y-125)^2=2500$

Question:

The quantities x and y are proportional.

$x\ \ \ \ \ \ \ \ \ \ y \\1\frac{2}{9}\ \ \ \ \ \ \ 2\frac{1}{3}$

Find the constant of proportionality (r)

Answer:

$r = 1\frac{10}{11}$

Step-by-step explanation:

Given

$x\ \ \ \ \ \ \ \ \ \ y \\1\frac{2}{9}\ \ \ \ \ \ \ 2\frac{1}{3}$

Required

Determine the constant of proportionality (r)

Constant of proportionality (r) is calculated as

$y = rx$

When

$y = 2\frac{1}{3}$ $x = 1\frac{2}{9}$

Substitute these values in the given formula

$2\frac{1}{3} = r * 1\frac{2}{9}$

Convert both fractions to improper fractions

$\frac{7}{3} = r * \frac{11}{9}$

Multiply both sides by $\frac{9}{11}$

$\frac{7}{3} * \frac{9}{11}= r * \frac{11}{9} * \frac{9}{11}$

$\frac{7}{3} * \frac{9}{11}= r$

Reorder

$r = \frac{7}{3} * \frac{9}{11}$

$r = \frac{7 * 9}{3 * 11}$

Divide the numerator and denominator by 3

$r = \frac{7 * 3}{11}$

$r = \frac{21}{11}$

Convert to mixed fraction

$r = 1\frac{10}{11}$

Hence, the constant of proportionality is $1\frac{10}{11}$

|5x|+5=45 can you explain this absloute value equation i have a midterm

Ymorist [56]

So first, you get the absolute value to one side:
$|5x|+5=45\\
|5x|=40$

Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:
$|5x|=40\\5x=40\\x=\frac{40}{5}=8\\\\-5x=40\\x=\frac{40}{-5}=-8$

Your answers are 8 and -8, or +-8.
