Find the scale factor where the pre-image is the small triangle and the image is the large triangle.
Oduvanchick [21]

Answer:

The scale factor is \frac{9}{7}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

so

\frac{18}{14}=\frac{27}{21}=\frac{9}{7}

therefore

The scale factor is 9/7

Find the value of x

The value of x is equal to  

\frac{x}{28}=\frac{9}{7}

x=28(\frac{9}{7})=36\ units

Which expression is equivalent to log Subscript 5 Baseline (StartFraction x Over 4 EndFraction) squared?
SIZIF [17.4K]

Answer:

\log_5(\frac{x}{4})^2 = 2\log_5(x) - 2\log_5(4)

Step-by-step explanation:

Given

\log_5(\frac{x}{4})^2

Required

The equivalent expression

To do this, we apply the following law of indices:

\log_a(b)^c = c\log_a(b)

So, we have:

\log_5(\frac{x}{4})^2 = 2\log_5(\frac{x}{4})

To further simplify:

\log(\frac{a}{b}) = \log(a) - \log(b)

So, we have:

\log_5(\frac{x}{4})^2 = 2(\log_5(x) - \log_5(4))

Open brackets

\log_5(\frac{x}{4})^2 = 2\log_5(x) - 2\log_5(4)
