Write an appropriate inverse variation equation if y = 9 when x = 3.
pav-90 [236]
\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad  y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
y=9\\
x=3
\end{cases}\implies 9=k3\implies \cfrac{9}{3}=k\implies \boxed{3=k}

What is 7.3 as a fraction
Snezhnost [94]
To write 7.3 as a fraction you have to write 7.3 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
7.3 = 7.3/1 = 73/10

And finally we have:
7.3 as a fraction equals 73/10

Match each function with its domain.
kari74 [83]

What you meant was range. The range scales from top to bottom. You can know this by graphing and practicing memorizing these function's domain and range.

Function:                  Range:

f(x) = -√x                    y ≤ 0

p(x) = ∛2-x          All real numbers

w(x) = 2 + √x             y ≥ 2

r(x) = -2 + √2-x          y ≥ -2

k(x) = 2 - √x               y ≤ 2

v(x) = √-x                   y ≥ 0

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.​
Debora [2.8K]
<h3>Question:</h3>

The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x.

<h3>To find:</h3>

  • Area in terms of x

<h3>Given:</h3>

  • Perimeter = 30 cm

  • L = x

<h3>Answer :</h3>

<u>To</u><u> </u><u>find</u><u> </u><u> </u><u>area</u><u> </u><u>first</u><u> </u><u> </u><u>we</u><u> </u><u>should</u><u> </u><u>know</u><u> </u><u> </u><u>value</u><u> </u><u> </u><u>of</u><u> </u><u>with</u><u>.</u>

So first Let's find width by using this formula:

\blue{\boxed { \sf \underline {Perimeter=2(Length+Width)}}}

Insert Value of length and perimeter.

:  \implies \sf 30 = 2(x + width)

:  \implies \sf  \dfrac{30}{2} = (x + width)

:  \implies \sf{}x + width =  \dfrac{ { \cancel{30}}^{ \: 15} }{ { \cancel{2}}^{ \: 1} }

:  \implies \sf{}x + width = 15

:  \implies \sf{}  \star \underline{\underline{ width = 15 - x}} \star

Now Let's find Area by using this formula

\blue{\boxed { \sf \underline {Area=Length \times Width }}}

: \implies \sf{}Area = x \times (15 - x)

:  \implies \sf{}  \star \underline{\underline{ Area = 15x -  {x}^{2}  \: cm {}^{2} }} \star

hope it helps!

Forces with magnitudes of 2000 newtons and 900 newtons act on a machine part at angles of +30degrees and -45degrees respectively
mote1985 [20]

To get the resultant magnitude and direction of the forces we need to separate the force into its x and y components. For the x components it is the sum of 2000cos(30) and 900cos(45), which is 2368.4469 N. For the y components it will be the sum of 2000sin(30) and -900sin(45), the value for the second force is negative because it is pointing downwards, their sum would be 363.6038 N. The magnitude for the resultant force can be determined using the pythagorean theorem R=sqrt(2368.4469^2 + 363.6038^2) while its direction is found using tan^-1(363.6038/2368.4469). The final answer would be 2396.1946 N with an angle of 8.7279 degrees from the right side of x axis.
