Answer:

Option A is correct

1008 \pi \text{units}^3

Step-by-step explanation:

Volume of cylinder(V) is given by:

V = \pi r^2h

where,

r is the radius of the cylinder and h is the height of the cylinder respectively.

As per the statement:

Radius of the cylinder(r) = 12 unit and height of the cylinder(h) = 7 units

Substitute the given values in [1] we have;

V = \pi \cdot 12^2 \cdot 7

⇒V = \pi \cdot 144 \cdot 7 = 1008 \pi cubic units.

Therefore, the volume of the cylinder is, 1008 \pi \text{units}^3

The volume:
Pi x r^2 x h

V = pi x 12^2 x 7
V = 1008pi units^3

Dennis decided he wanted to go to the carnival. The carnival charges $6.00 for entry and $1.50 for each ride.
myrzilka [38]

We want to create a linear equation to model the given situation.

A) c(r) = $6.00 + $1.50*r

B) 19 rides.

We know that the carnival charges $6.00 for entry plus $1.50 for each ride.

A) With the given information we can see that if you ride for r rides, then the cost equation will be:

c(r) = $6.00 + $1.50*r

Where c(r) is the cost for going to the carnival and doing r rides.

B) If you have $35.00, then we can solve:

c(r) = $35.00 =  $6.00 + $1.50*r

Now we can solve the equation for r.

$35.00 =  $6.00 + $1.50*r

$35.00 -  $6.00 = $1.50*r

$29.00 = $1.50*r

$29.00/$1.50 = r = 19.33

Rounding to the next whole number we get: r = 19

This means that with $35.00, Dennis could go to 19 rides.

The roots of x2 − ( ) + 34 are 5 ± 3i.
Angelina_Jolie [31]
Use quadratic formula
if you had ax^2+bx+c=0, then
x=\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}
a=1
b=?
c=34
subsitute
\frac{-b+/- \sqrt{b^{2}-4(1)(34)} }{2(1)}=5+/-3i
\frac{-b+/- \sqrt{b^{2}-136} }{2}=5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2
\frac{-b+/- \sqrt{b^{2}-136} }{2}=(10+/-6i)/2
multiply both sides by 2
-b+/- \sqrt{b^{2}-136}=10+/-6i
we conclude that -b=10
b=-10

ok so equaton is
x^2-10x+34

What is the slope of a line that is perpendicular to the line with equation 12x+3y=9?
Masteriza [31]

Answer:

perpendicular slope= 1/4

Step-by-step explanation:

you have to make the equation equal to y so that would be -4x+3=y

and then you just find the negative reciprocal of the slope -4 which would be 1/4
