Find the surface area of the figure shown,<br> correct to 2 decimal places.

agasfer [191]

Answer:

$230.73m^2$

Step-by-step explanation:

$A=2a^2+4ah=2*4^2+4*4*4=96m^2$ (square prism)

$A=2\pi rh+2\pi r^2=2*\pi *4*9+2*\pi *4^2 = 326.73m^$ (cylinder)

$326.73-96=230.73m^2$ ( $\frac{3}{4}$ cylinder)

Find the square of the following without actual multpliation .<br><br> 43

devlian [24]

I'll explain how I found it without actual multiplication,

${40}^{2} = 1600 \\ {3}^{2} = 9 \\ 2 \times 40 \times 3 = 240 \\$

So,

${43}^{2} = 1600 + 240 + 9 \\ = 1849$

Hope this will help....

Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x2?

Aliun [14]

Answer:

The last choice is the one you want

Step-by-step explanation:

First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.

The second one factored becomes:

$g(x)=4(x-3)^2+1$

which reflects a shift to the right 3 and up 1. Not what we are asked to find.

The fourth one factored becomes:

$g(x)=8(x-3)^2-5$

which reflects a shift to the right 3 and down 5. That's what we want!
