Since the scale factor is 4:3 then every dimension of triangle WXY is (3/4) of every dimension of triangle CDE.
The perimeter of triangle CDE = 13 + 22 + 29 = 64.
So, the perimeter of triangle WXY = (3/4) * 64 = 48

Let f(x) = <br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B11x%20-%203%20%5C%3A%7D%20determine%20%5C%3A%20%20%7Bf%7D%5

Step-by-step explanation:

Set up f(x).

$\sqrt[3]{11x - 3} = f(x)$

Replace f(x) with y

$\sqrt[3]{11x - 3} = y$

Swap x and y

$\sqrt[3]{11y - 3} = x$

Solve for y

Cube both sides

$11y - 3 = {x}^{3}$

Add 3 to both sides

$11y = {x}^{3} + 3$

Divide both sides by 11

$y = \frac{x {}^{3} + 3 }{11}$

$f {}^{ - 1} (x )= \frac{ {x}^{3} + 3}{11}$

a cup was filled at a constant rate. it started empty. after 2 seconds, it held 70 cm cubes of water. the radius is 4 and te hei

Viktor [21]

Answer:

89.51%

Step-by-step explanation:

Assuming given units are in cm

Tge rate of filling the cup is 70/2= 35 cm3/s

Volume of the cup is $\pi r^{2}\frac {h}{3}$ and replacing r with 4 cm and h with 7 cm then the volume is equivalent to

$\pi*4^{2}*\frac {7}{3}= 117.3 cm^{3}$

Volume filled after 3 seconds will be 3*35=105 cm3

Percentage filled is $\frac {105}{117.3}\times 100\approx 89.51$
