A triangular pyramid has an isosceles triangular base. The base edge of the triangular base is 10

Mathematics
1 answer:
tester [92]3 years ago
7 0

Answer:

h=94.87

Step-by-step explanation:

1. Volume of pyramid formula:

v=\frac{1}{3}*a^{2}*h

a=b*h Base Edge * Height of Pyramid

2. We have variables:

V = 480, Base Edge = 10, Height of Base = 16 (Inch)

3. Plug into formula + Rearrange:

\frac{3V}{h} =(b*h)^{2} [b^{2} *h^{2} ]

\frac{3V*b^{2} }{h} =h^{2}

h^{2}=\frac{3*480*10^{2} }{16}

h=\sqrt{9000}

h≅94.868

A paddle wheel on a boat is 12 feet in diameter. The fins along the outer edge travel at
irina1246 [14]

Answer:

Explanation:

First, we must determine the circumference of the paddle wheel.

The formula for the circumference of a circle is:

c

=

2

π

r

Where  

r

is the radius of the circle.

However, we know  

d

=

2

r

where  

d

is the diameter of the circle.

Therefore:

c

=

2

r

π

=

d

π

Substituting  

12

ft

for  

d

gives a circumference of:

c

=

12

π

ft

The time it takes to complete 1 revolution can be found using the formula:

t

=

d

s

Where:

t

is the time it takes: what we are solving for in this problem.

d

is the distance traveled: we calculated this as  

12

π

ft

s

is the speed traveled: from the problem we know this is  

7.2

ft

sec

Substituting and calculating  

t

gives:

t

=

What is the quotient of the synthetic division problem below, written in polynomial form?
iris [78.8K]

Answer:

Step-by-step explanation:

If we have 5 terms to the right of the -1 outside the box thing, that means that our original polynomial is a 4th degree (the degree is one lower than the number of terms in order to allow for the constant which has no variable). Set up the synthetic division as shown in the problem. The rule is to bring down the first term, the 1 to the right of the box, multiply it by the number outside, -1, and put that product up under the next number in line inside the box. Like this:

-1 |   1    7     15     9     7

<u>           -1                        </u>

      1  

Now add straight down, multiply the sum by -1 and put that product up under the next term in line, the 15:

-1 |   1     7     15     9     7

<u>             -1     -6               </u>

      1     6  

Then add straight down again, multiply the sum by -1 and put that product up under the next term in line, the 9:

-1 |     1     7     15     9     7

<u>               -1     -6    -9       </u>

        1     6     9

Then do the same thing. Add straight down, multiply the sum by -1 and put the product up under the next term in line, the 7:

-1 |     1     7     15     9     7

<u>               -1     -6    -9     0</u>

        1     6      9     0     7

This is the final result. The last number, the 7 is the remainder, but the rest of it makes up what we call the depressed polynomial and is a polynomial that is one degree less than the degree we started with. So this depressed polynomial is a 3rd degree. The numbers are the coefficients on the x terms:

1x^3+6x^2+9x+0R7 or more simply stated:

x^3+6x^2+9xR7
