1 answer:

5 0

<h2>Domain: {0, 2}</h2><h2>Range: {0, 1, 1}</h2><h2 /><h3>When dealing with the domain, remember that no numbers can repeat in the domain so if there is more than one of the same number, we only list it one.</h3><h3 /><h3>When dealing with the range, it's ok if numbers repeat because it's the y-value not the x-value.</h3><h3 /><h3 />

igomit [66]

Answer:

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

$a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2$

#We then calculate the campus' map area in square ft:

$A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2$

Ratio is a comparison between two dimensions:

$Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4$

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4

Simplify this expression: cos t(sec t − cos t)

Nostrana [21]

$\cos t \, (\sec t - \cos t)$
$= \cos t \, (\frac{1}{\cos t} - \cos t)$
$= 1 - \cos^2 t$
$= \bf sin^2 t$

What is the value of the exponential expression 36 1/2

garik1379 [7]

For this case we have an exponential expression of the form:
$36^{ \frac{1}{2}}$
We can rewrite the exponential expression using power properties.
We have then:
$\sqrt{36}$
From here, we take the square root of 36.
We have then:
$\sqrt{36} = 6$
Answer:
The exponential function is given by:
$36^{ \frac{1}{2}}=6$
