F(x) = 3x2 - 7 and g(x) = x3 + 1, evaluate f(g(2)). NEED HELP PLEASEE??
Triss [41]
F(g(2)) = 3(x^3 + 1)^2 - 7 = 3(x^6 + 2x^3 + 1) - 7 = 3x^6 + 6x^3 + 3 - 7 = 3x^6 + 6x^3 - 4

I need to know what the answer is the question is Josie bikes 40 miles each months for five months she multiplies 40×5 what unit
sleet_krkn [62]
The product would be 200 obliviously it would be miles because it says five months so it’s implying that you need to find the amount biked in 5 months

So it’s should be miles

Answer. To verify that the decimals are lined up correctly, we must ensure that they are both lined up at the same point. The reason this is done is so that whole numbers will be subtracted from other whole numbers, not decimals.
Extra. Hope this helped, if it’s correct let me know so others can use it :)
Good luck :)

A punch bowl is in the shape of a hemisphere​ (half of a​ sphere) with a radius of 10 inches. The cup part of a ladle is also in
prisoha [69]

Answer:

There are 4 full ladles of punch in the bowl.

Step-by-step explanation:

Given the radius ''R'' the volume of a sphere is :

V=\frac{4}{3}(\pi)R^{3}

Therefore, the volume of half of a sphere is :

V(HalfOfASphere)=\frac{V(Sphere)}{2}

V(HalfOfASphere)=\frac{2}{3}(\pi)R^{3}

Let's start calculating the volume of the punch bowl (inches = in) :

V(PunchBowl)=\frac{2}{3}(\pi)(10in)^{3}=\frac{2000}{3}(\pi)in^{3}

Now we calculate the volume of the cup part of the ladle :

V(Ladle)=\frac{2}{3}(\pi)(6in)^{3}=144(\pi)in^{3}

Finally we divide the volume of the punch bowl by the volume of the ladle

\frac{V(PunchBowl)}{V(Ladle)}=\frac{\frac{2000}{3}(\pi)in^{3}}{144(\pi)in^{3}}=4.63

They are 4.63 ladles in the punch bowl. Therefore, there are 4 full ladles of punch in the bowl.
