Answer:

The surface area is $0.64\ m^{2}$

Step-by-step explanation:

we know that

The surface area of a square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces.

so

$SA=b^{2}+4[\frac{1}{2}(b)(l)]$

we have

$b=0.4\ m$

$l=0.6\ m$

substitute the values

$SA=0.4^{2}+4[\frac{1}{2}(0.4)(0.6)]=0.64\ m^{2}$

What is the area of polygon LMN? <br><br> A. 50<br> B. 60<br> C. 65<br> D. 70<br> E.80

Verdich [7]

Answer:

c:65

Step-by-step explanation:

The area of a triangle can be found almost the same way as a sqaure L*W (Length times width). Except the area of a triangle is one half that of a square, so it is $\frac{1}{2}$ L*W. The length is 13 and the width is 10, so 13*10=130, than 1/2 that is 65.

What does this mean? Test the residuals of two other points to determine how well the line of best fit models the data.

kiruha [24]

A residual is a measure of how well a line fits an individual data point. Testing the two other points can really help to see how well the line fits.

Rewrite in simplest rational exponent form <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%2A%20%5Csqrt%5B4%5D%7Bx%7D" id="T

The given expression written in the simplest rational exponent form is $x^{\frac{3}{4} }$

<h3>Writing an Expression in Exponent form</h3>

From the question, we are to write the given expression in exponent form

The given expression is

$\sqrt{x} \times \sqrt[4]{x}$

In exponent form,

$\sqrt{x} = x^{\frac{1}{2} }$

and

$\sqrt[4]{x} = x^{\frac{1}{4} }$

Thus, $\sqrt{x} \times \sqrt[4]{x}$ becomes

$x^{\frac{1}{2} } \times x^{\frac{1}{4} }$

Applying the multiplication law of indices, we get

$x^{\frac{1}{2} + \frac{1}{4} }$

= $x^{\frac{3}{4} }$

Hence, the given expression written in the simplest rational exponent form is $x^{\frac{3}{4} }$
