Answer:

Step-by-step explanation:

g(x) = x² + 2x+4

h(x) = -3x+2

(g*h)(1) is the same as

g(h(1)) , next solve for h(1) first by substituting in h(x), x with 1

g( h( x= 1)) = g( -3*1 +2) = g( -1) so substitute in g(x) , x with -1

g(x= -1) = (-1)² +2(-1) +4 =1-2+4 =3

Find the volume of the figure.

jeka57 [31]

Hello from MrBillDoesMath!

Answer:

1283.3

Discussion:

Volume of figure =

volume of cone + volume of cylinder =

(1/3) Pi r^2 h + Pi r^2 h =

(1/3) Pi (7)^2* 7 + Pi (7)^2 * 6 =

Pi * 7^2 ( (1/3) *7 + 6) = => using PI is approx 22/7

(22/7) * 7^2 ( 7/3 + 6) =

(22/7)* 49 (25/3) = 1283.3

Thank you,

Three years ago, the annual tuition at a university was $2,000. The following year, the tuition was $2,200, and last year, the t

blondinia [14]

It grows by 10% each year. multiply the number by 0.1, then add. so 0.1×2420 is 242. add 242+2420=2662.

short answer:
this years tuition is $2662.
next years tuition is $2928.

Find the value of a and b if root3-1/root3+1+ root3+1/root3-1=a+root3 b

Digiron [165]

Answer:

a=4 and b = 0

Step-by-step explanation:

Given : $\dfrac{\sqrt 3 -1}{\sqrt 3+1}+\dfrac{\sqrt 3+1}{\sqrt 3-1}=a+\sqrt 3 b$

To find, The value of a and b

Solution,

Solving LHS of the given equation,

$\dfrac{(\sqrt 3-1)^2+(\sqrt3+1)^2}{(\sqrt 3+1)(\sqrt 3-1)}=a+\sqrt 3 b$

Since,

$(a-b)^2=a^2+b^2-2ab\\\\(a+b)^2=a^2+b^2+2ab\\\\(a-b)(a+b)=a^2+b^2$

So,

$\dfrac{3+1-2\sqrt 3+3+1+2\sqrt 3}{3-1}=a+\sqrt 3 b\\\\4=a+\sqrt 3 b$

$4+0=a+\sqrt 3 b$

On comparing we get :

a = 4 and b = 0
