The length of the square pool is 8. 49cm

<h3>How to determine the area</h3>

Note that the formula for finding the area of a square is given as;

Area = length^2

We have

Area = 72 m²

Substitute into the formula

I^2 = 72

Find the square root of both sides

I= √72

I = 8. 49cm

The length of the square pool given as I is 8. 49cm

Thus, the length of the square pool is 8. 49cm

Tamiku [17]

The parameterize is  128 \pi

In mathematics, and extra in particular in geometry, parametrization (or parameterization; additionally parameterization, parametrization) is the method of locating parametric equations of a curve, a surface, or, greater typically, a manifold or an expansion, described by using an implicit equation.

"To parameterize" by means of itself method "to specific in terms of parameters". Parametrization is a mathematical technique that includes expressing the state of a system, system, or model as a feature of some independent portions referred to as parameters.

Instance 1. find a parametrization of the road through the points (three,1,2) and (1,0,5). answer: the road is parallel to the vector v=(3,1,2)−(1,0,five)=(2,1,−3). subsequently, a parametrization for the line is x=(1,0,five)+t(2,1,−3)for−∞

Does a rectangle have one line of symmetry
Thepotemich [5.8K]

No, it has more than one. A rectangle is symmetric with respect to its diagonals, and the lines connecting the midpoints of two opposite sides.

Which function is equivalent to y=x2-10x+9?
Mashcka [7]

Figure out the equation for each of the multiple choice.

Then you will get the answer .

For example:

a. (x+5)(x+5) +16

= x^2 + 5x+5x+25+16

= x^2+10x+41

30° + 180° (2n + 1), its radian measure is equivalent to?​
Nuetrik [128]

Answer:

Example: Find the radian measure of the angles −70° and 120°.

Solution: To find the radian measure of −70° we multiply −70 by the conversion factor /180. We get

Similarly, for 120° we obtain

Note that when we write an angle as a fractional amount of , for example 2/3 times  we write the result either as the numerator times  divided by the denominator or as the fraction times . So the two values

are equivalent ways of writing the same number. You will see both methods used in the text and in the exercises.

Example: Find the degree measure of /12.

Solution: The conversion factor for going from radians to degrees is 180/. We get

and so the radian measure of /12 is 15°.
