Let
<span>p ----------------> is the perimeter of the base
</span><span>h ---------------> is the height
</span><span>BA------------->  is the area of the bases
</span><span>LA--------------> is the lateral area

we know that surface area is </span><span>the sum of base areas plus lateral areas 
</span><span>then
SA=[BA]+P*h
but remember that
LA=P*h
then
SA=</span>[BA]+LA----------> SA=BA+LA

the answer are the options B.) SA=BA+LA and the option D.) SA=BA+ph

please help :) What is 7.7 x 10 to the 8 power written in standard form? A. 770,000,000 B. 77,000,000,000 C. 77,000,000 D. 7,700
Serjik [45]

Answer:

A. 770,000,000

Step-by-step explanation:

7.7x10^8 First step is to simplify

7.7x100,000,000 Then, multiply

770,000,000

Hope this helps, if it does, please consider giving me brainliest, it will help me a lot. If you still have any questions, feel free to ask.

Have a good day! :)

1.Use the diagram of the regular hexagon to support an explanation showing why the formula accurately yields the area of the hex
alekssr [168]
Even though im not giving you the whole answer, let me give you something that will definitely help you:
a regular hexagon is made of 6 identical triangles with the apothem as the height of the triangle A = 6 * 1/2 base * apothem which can be simplified to A = 1/2 perimeter * apothem
This in itself is a big part of what you need. I hope this is enough info for you to keep going

Use Lagrange multipliers to find the maximum and minimum values of f(x,y)=x+4y subject to the constraint x2+y2=9, if such values
Vesnalui [34]

The Lagrangian is

L(x,y,\lambda)=x+4y+\lambda(x^2+y^2-9)

with critical points where the partial derivatives vanish.

L_x=1+2\lambda x=0\implies x=-\dfrac1{2\lambda}

L_y=4+2\lambda y=0\implies y=-\dfrac2\lambda

L_\lambda=x^2+y^2-9=0

Substitute x,y into the last equation and solve for \lambda:

\left(-\dfrac1{2\lambda}\right)^2+\left(-\dfrac2\lambda\right)^2=9\implies\lambda=\pm\dfrac{\sqrt{17}}6

Then we get two critical points,

(x,y)=\left(-\dfrac3{\sqrt{17}},-\dfrac{12}{\sqrt{17}}\right)\text{ and }(x,y)=\left(\dfrac3{\sqrt{17}},\dfrac{12}{\sqrt{17}}\right)

We get an absolute maximum of 3\sqrt{17}\approx12.369 at the second point, and an absolute minimum of -3\sqrt{17}\approx-12.369 at the first point.
