Well a perfect square looks like this:

6 x 6
2 x 2

So the number 72 is between the PRODUCT of two perfect squares such as those.

One product has to be above 72, and the other below it.

So lets multiply.

8 x 8 = 64
9 x 9 = 81

Oh look at that, 72 is between 64 and 81.

64=8^2
81 = 9^2

72 is between what two perfect squares 64=8^2 and 81 = 9^2

Which is equivalent to sin^-1(.75)

Neko [114]

<h2>Answer: 0.85 radians</h2>

Step-by-step explanation:

We have the following trigonometric expression:

$sin^{-1}(0.75)=arcsin(0.75)$

The result of this calculation is:

$sin^{-1}(0.75)=48.59\°$ where the angle is in degrees

If $360\°=2\pi rad$ then:

$48.59\°(\frac{2\pi rad}{360\°}=0.848 rad \approx 0.85 rad$

Therefore the answer is 0.85 radians

PLEASE HELP ME ...........Julie was looking at the architect's blueprint of her house. The scale on blueprint was 1/4 inch = 1 f

MAVERICK [17]

Answer:

On the blueprint the dimensions are <u>48 inches by 64 inches</u>.

Step-by-step explanation:

Given:

The scale on blueprint was 1/4 inch = 1 foot.

The actual dimensions of her bedroom are 12 feet by 16 feet.

Now, to find the dimensions on the blueprint.

Let the dimensions on the blueprint be $x$ by $y.$

As, given the scale on blueprint:

$\frac{1}{4}\ inch=1\ foot$

So, $\frac{1}{4}\ inch$ is equivalent to 1 foot.

Thus, $x$ is equivalent to 12 feet.

And, $y$ is equivalent to 16 feet.

Now, solving by cross multiplication method:

$\frac{\frac{1}{4}}{1} = \frac{x}{12}$

$\frac{4}{1} =\frac{x}{12}$

<em>By cross multiplying we get:</em>

$48=x$

$x=48\ inches.$

Now, again:

$\frac{\frac{1}{4}}{1} =\frac{y}{16}$

$\frac{4}{1} =\frac{y}{16}$

<em>By cross multiplying we get:</em>

$64=y$

$y=64\ inches.$

Therefore, on the blueprint the dimensions are 48 inches by 64 inches.
