Answer:

Soccer = 120

Tennis = 220

Step-by-step explanation:

The total number of students enrolling for soccer and tennis classes is, 340.

The ratio number of students enrolling for soccer and tennis classes is, 6:11.

Then,

6x + 11x = 340

17x = 340

x = 20

The number of students enrolled for soccer class is, 6x = 6 × 20 = 120.

The number of students enrolled for tennis class is, 11x = 11 × 20 = 120.

Please Help! What is the distance between points (2, 8) and (7, 5)? Round to the nearest tenth of a unit.

zavuch27 [327]

Distance formula is like pythagoren ahtoerem
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
the distance between oints (x1,y1) and (x2,y2) is
D= $\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$
(2,8) and (7,5)
D= $\sqrt{(7-2)^{2}+(5-8)^{2}}$
D= $\sqrt{(5)^{2}+(-3)^{2}}$
D= $\sqrt{25+9}$
D= $\sqrt{34}$
apxos
D=5.8309....

round
D=5.8 units

The function of (x) varies directly with x^2, and f(x)=96 when x=4 what is the value of f(2)

makkiz [27]

$\bf \qquad \qquad \textit{direct proportional variation}
\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \textit{f(x) varies directly with }x^2\qquad f(x)=kx^2
\\\\\\
\textit{we also know that }
\begin{cases}
f(x)=96\\
x=4
\end{cases}\implies 96=k(4)^2\implies 96=16k
\\\\\\
\cfrac{96}{16}=k\implies 6=k\qquad therefore\qquad \boxed{f(x)=6x^2}
\\\\\\
\textit{now, when }\stackrel{f(2)}{x=2}\textit{ what is \underline{f(x)}?}\qquad f(2)=6(2)^2$
