Irina-Kira [14]

Answer:

$\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }$

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

$f(g(x))=f(x+1)=4(x+1)^2$

so C is the correct answer

Martine’s town is building a volleyball court based on a scale drawing that is 40cm to 80cm and uses the scale 1cm:22.5cm write

never [62]

Answer:

$y=22.5x$

Step-by-step explanation:

we have that

The scale drawing is

$\frac{1}{22.5}\frac{cm}{cm}$

we know that

Using proportion find out the actual dimensions of the volleyball court

Let

x -----> drawing court lengths in cm

y ----> court lengths in cm

For x=40 cm

$\frac{1}{22.5}\frac{cm}{cm}=\frac{40}{y}\frac{cm}{cm}\\\\y=40*22.5\\\\y=900\ cm$

For x=80 cm

$\frac{1}{22.5}\frac{cm}{cm}=\frac{80}{y}\frac{cm}{cm}\\\\y=80*22.5\\\\y=1,800\ cm$

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

For x=40 cm, y=900

substitute

$k=y/x$ -----> $k=900/40=22.5$

The equation is

$y=22.5x$

\log_{4} x + \log_{4} (x+5) = 6

irina1246 [14]

log(4)x + log(4)(x + 5) = 6
log(4)x + log(4)x + log(20) = 6
 log(8)x + log(20) = 6
 - log(20) - log(20)
 log(8)x = 6 - log(20)
 log(8) log(8)
 x ≈ 0.999
