Answer:

384π cm³ ≈ 1206.37 cm³

Insert the values the problem gives to us.

V = π(12)²(8)/3

⇒ π(144)(8)/3

⇒ 384π ≈ 1206.37

A garden has 8 white roses and 11 red roses. One rose is plucked from the garden and then one more rose is plucked without repla
liberstina [14]
P(r/w) is the probability of picking a red rose at first picking and a white rose at second picking.
P(w/r) is the probability of picking a white rose at first picking and a red rose at second picking.

P(r/w) = \frac{11}{19}×\frac{8}{18} = \frac{88}{342}
P(w/r) = \frac{8}{19}×\frac{11}{18}=\frac{88}{342}

Notice that the second fraction is out of 18 because the second picking of rose will be out of 18 since the first rose is not replaced.

P(r/w) equals to P(w/r)

What is the answer to this problem
Tpy6a [65]

Step One

Solve for CE as a numerical value

CE = 1/2 * CD = 1/2 66 = 33

CE = 33

Step Two

Solve for x

CD also equals x^2 - 3     which is given.

x^2 - 3 = 33                       Add 3 to both sides

x^2 = 33 + 3

x^2 = 36                            Take the square root of both sides

sqrt(x^2) = sqrt(36)

x = 6

Step 3

Find the length of AE

AE is given as 6x - 10

x = 6

AE = 6*6 - 10

AE = 36 - 10

AE = 26

Step 4

Find AB

AE = 1/2 AB                  Definition of bisect

26 = 1/2 AB                  Multiply by 2

2*26 = AB

AB = 52       <<<<<<<<Answer

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at
aksik [14]
The formula for the area of a triangle is
A=\frac{1}{2}bh
\rightarrow\frac{dA}{dt}=\frac{1}{2}(b\frac{dh}{dt}+h\frac{db}{dt})

We are given:
\frac{dh}{dt}=2
\frac{dA}{dt}=4.5
h=9.5
A=92

Plug in:
4.5=\frac{1}{2}(b*2+9.5\frac{db}{dt})
We can find b with:
A=\frac{1}{2}bh\rightarrowb=\frac{2A}{h}=\frac{2*92}{9.5}=\frac{184}{9.5}
So 4.5=\frac{1}{2}(2*\frac{184}{9.5}+9.5\frac{db}{dt})
\rightarrow9=\frac{368}{9.5}+9.5\frac{db}{dt}
\rightarrow9-\frac{368}{9.5}=9.5\frac{db}{dt}
\rightarrow\frac{db}{dt}=\frac{9-\frac{368}{9.5}}{9.5}\approx-3.130

So the base is decreasing at a rate of 3.130 cm/minute.
