Answer:
94.2 in squared
Step-by-step explanation:
lateral area plus area of both flat sides
37.68 + 2(3.14*3^2)
37.68 + 56.52 = 94.2 in squared
<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM
</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.
anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.
there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.
Answer:
B
Step-by-step explanation:
Both B and C are right btw. Ratios can be both fractions and in the (x:Y) format.

Answer:
see the attachment
Step-by-step explanation:
The vertex form of the equation of a parabola is ...
y = a(x -h)^2 +k . . . . . . vertical scale factor "a", vertex (h, k)
For the given points, we have ...
1 = a(0 -3)^2 +5
-4 = 9a . . . . . . subtract 5 and simplify
-4/9 = a
So, the equation of the parabola is ...
y = (-4/9)(x -3)^2 +5
Its graph is shown below.
When you add up the measures of all three angles in a triangle,
they always add up to 180 degrees. It doesn't matter how large
or small the triangle is, or how skinny or fat it is. It's a triangle thing.
The angles always add up to 180 degrees.
An 'obtuse' angle is an angle that measures more than 90 degrees
but less than 180 degrees, so it's possible to have 1 obtuse angle
in a triangle. But if you have one, then that leaves less than 90 degrees
for the other two angles put together.
So both of the other ones must be less than 90 degrees each.
