Answer:

1/45

Step-by-step explanation:

There are 10 marbles

P ( yellow) = yellow marbles / total = 2/10 = 1/5

We do not replace the marble

There are 9 marbles, 1 of which is yellow

P ( yellow) = yellow marbles / total = 1/9

P ( yellow, no replacement, yellow) = 1/5 * 1/9 = 1/45

The answer is 1/45 because you multiply 2/10 by 1/9, which are the probabilities of both situations.

If f(x)=4x^2+1 and g(x) =x^2-5 find (f-g)(x)
docker41 [41]

Answer:

\huge\boxed{(f-g)(x)=3x^2+6}

Step-by-step explanation:

(f-g)(x)=f(x)(x)\\\\\text{substitute}\ f(x)=4x^2+1\ \text{and}\ g(x)=x^2-5\\\\(f-g)(x)=(4x^2+1)-(x^2-5)=4x^2+1-x^2-(-5)=4x^2+1-x^2+5\\\\\text{combine like terms}\\\\(f-g)(x)=(4x^2-x^2)+(1+5)=3x^2+6

A cylinder has a radius of 10cm and a height of 9cm. A cone has a radius of 10cm and a height of 9 cm. Show that the volume of t
nlexa [21]

Answer:

The answer in the procedure

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

V=\pi r^{2} h

we have

r=10\ cm

h=9\ cm

substitute

V=\pi (10)^{2}(9)=900\pi\ cm^{2}  

step 2

Find the volume of the cone

The volume of the cone is equal to

V=(1/3)\pi r^{2} h

we have

r=10\ cm

h=9\ cm

substitute

V=(1/3)\pi (10)^{2}(9)=300\pi\ cm^{2}  

therefore

we have

Vcylinder=900\pi\ cm^{2}  

Vcone=300\pi\ cm^{2}  

so

Vcylinder=3Vcone
